This article presents results from two studies of Washington State's prison work release program conducted between 1991 and 1994. The first study analyzed a cohort of all male prisoners released from Washington prisons in 1990 (N = 2,452) to describe how work release operates and how successfully inmates perform in the program. The second study compared the recidivism of 218 offenders, approximately half of whom participated in work release and half of whom completed their sentences in prison. Results of the evaluation were mostly positive. Nearly a quarter of all prisoners released made a successful transition to the community through work release. Few work release inmates committed crimes while on work release. Recidivism and correctional costs for work releases and nonwork releases were similar.

"A comparison of the release of a vasoactive-intestinal-peptide-like peptide and acetylcholine in the giant axon-Schwann cell preparation of the tropical squid Sepioteuthis sepioidea." Journal of Experimental Biology 202, no. 4 (1999): 417–28. http://dx.doi.org/10.1242/jeb.202.4.417.
Full textAbstract:
A vasoactive intestinal peptide (VIP)-like peptide is released by axonal stimulation in the giant axon-Schwann cell preparation from the tropical squid Sepioteuthis sepioidea. It is also released by direct application of l-glutamate, the giant axon-Schwann cell signalling molecule in this preparation. The release of the peptide parallels the release of acetylcholine from the Schwann cells themselves in this preparation in a number of different ways. The release of both acetylcholine and the VIP-like peptide have the same threshold (between 2×10(−10) and 5×10(−10)mol l-1) for l-glutamate application and the same recovery time after inhibition of release by exposure of the preparation to a prolonged pulse of l-glutamate. A prolonged l-glutamate pulse of 10(−8)mol l-1 releases both substances for as long as the pulse is applied to the preparation, whereas a prolonged pulse of 10(−9)mol l-1 l-glutamate releases acetylcholine in the same way but releases the VIP-like peptide only transiently. The VIP-like peptide is likely to be co-released with acetylcholine from the Schwann cells.

The braconid parasitoid Microctonus hyperodae was released in New Zealand for biological control of Argentine stem weevil Listronotus bonariensis The initial 1991 research introduction involved the release of 99000 parasitised L bonariensis Between 1991 and 1998 a further 660000 M hyperodae were released as part of commercial contracts and research programmes Commercial contracts resulted in the widespread release of the parasitoid in the North Island with South Island releases mainly confined to midCanterbury There were eight geographic populations originally collected from South America and these were maintained separately in the laboratory Excluding the Mendoza population which was founded on a single female an average of 91040 M hyperodae was released from each of the seven remaining populations Parasitised L bonariensis were released at a total of 121 sites and the parasitoid established at 118 (975) Based on the distribution of releases in New Zealand and the results of surveys it is estimated that M hyperodae is now very widely distributed in the North Island with more limited distribution in the South Island

Full textAbstract:
Fifty-three captive-bred New Zealand Shore Plover (Thinornis novaeseelandiae) were released on Motuora Island in the Hauraki Gulf, New Zealand in an attempt to establish a second population of this endangered shorebird in the wild. The birds were liberated in four releases between September 1994 and February 1997. In September 1997, eight (15%) of the released birds were still resident on Motuora Island. Dispersal to the mainland was the principal known cause of loss of birds from the island, with predation being the next most important cause. Differences were found between the use of adult and juvenile birds for release but there did not seem to be any difference between using hand- or parent-reared birds. Possible seasonal patterns of disappearance may become clearer once more birds have been released on the island. Recommendations for future management and research include continuing the transfer programme to Motuora Island with intensive monitoring during the first month after release, inclusion of more adult birds in releases, release of both hand- and parent-reared captive birds and conducting more research into Morepork predation of Shore Plover.

Full textAbstract:
ABSTRACTReleasing mosquito refractory to pathogens has been proposed as a means of controlling mosquito-borne diseases. A recent modeling study demonstrated that instead of the conventional male-only releases, adding blood-fed females to the release population could significantly increase the program’s efficiency, hastening the decrease in disease transmission competence of the target mosquito population and reducing the duration and costs of the release program. However, releasing female mosquitoes presents a short-term risk of increased disease transmission. To quantify this risk, we constructed a Ross–MacDonald model and an individual-based stochastic model to estimate the increase in disease transmission contributed by the released blood-fed females, using the mosquito Aedes aegypti and the dengue virus as a model system. Under baseline parameter values informed by empirical data, our stochastic models predicted a 1.1–5.5% increase in dengue transmission during the initial release, depending on the resistance level of released mosquitoes and release size. The basic reproductive number (R0) increased by 0.45–3.62%. The stochastic simulations were then extended to 10 releases to evaluate the long-term effect. The overall reduction of disease transmission was much greater than the number of potential infections directly contributed by the released females. Releasing blood-fed females with males could also outperform conventional male-only releases when the release strain is sufficiently resistant, and the release size is relatively small. Overall, these results suggested that the long-term benefit of releasing blood-fed females often outweighs the short-term risk.

Full textAbstract:
AbstractA field study was performed in southern Alberta, Canada, to assess the native wasp, Trichomalopsis sarcophagae (Gahan), as a potential biocontrol agent for house fly, Musca domestica L., and stable fly, Stomoxys calcitrans (L.). The wasp was readily reared in large numbers, which allowed for the cumulative release of an estimated 4.63 million wasps into three commercial feedlots during the 2-year study. Each of several releases predictably and repeatedly enhanced parasitism of sentinel house fly pupae, whereas parasitism remained low in three paired control feedlots where wasps were not released. Releases every 2nd week had a disproportionately greater effect than releases every 2nd month. In 1998, 1.2 million wasps were released into treatment feedlots resulting in the recovery of 3 952 T. sarcophagae from 31 500 sentinel pupae (0.13 wasps/pupa). In 1999, 3.43 million wasps were released into treatment feedlots, with the recovery of 37 763 wasps from 47 720 sentinel pupae (0.79 wasps/pupa). Hence, a 2.8-fold increase in the number of wasps released in 1999 resulted in a 6.1-fold increase in the recovery of wasps. This result supports industry recommendations of regular, repeated releases of wasps every 2nd or 4th week versus one or infrequent releases throughout the summer. There was no evidence that releases augmented overwintering populations of the wasp in subsequent years. These results provide proof-of-concept for the mass-rearing and release of T. sarcophagae as an inundative biocontrol agent for the control of pest flies in cattle confinements. Further studies will be required to assess the effect of T. sarcophagae releases on natural populations of pest flies.

Full textAbstract:
AbstractThe release and migration of gaseous carbon-14 has been identified as a key issue for geological disposal of intermediate-level radioactive wastes in the UK. A significant fraction of carbon-14 in the UK inventory is in irradiated graphite. This paper describes measurements of gaseous carbon-14 releases from irradiated graphite on immersion in alkaline solution. Apparatus has been developed to discriminate organic and inorganic (14CO/14CO2) species in the gas phase by means of selective oxidation and capture. In the initial experiment, small amounts of gaseous carbon-14 (∼4 Bq) were released from 9 g of crushed graphite within a two-week period. In a long-term experiment, cumulative releases were measured periodically from an intact specimen of graphite over a 14 month period. A small fraction of the graphite carbon-14 inventory was released to the gas phase (∼0.004% as CO/CO2 and ∼0.001% associated with organic compounds). A larger quantity of carbon-14, about 0.1%, was released to the solution phase and was thought to be mainly 14CO2, with some possible organic component. In general, the rate of gaseous carbon-14 release decreased with time. The results suggest a small initial release of relatively labile, accessible carbon-14, with longer term release occurring at a much slower rate. Tritium (T) releases were also measured.

Full textAbstract:
AbstractTwo systems for releasing the egg parasitoid, Trichogramma minutum Riley, from ground level in forest stands are described: (1) a gridded point-source release using parasitized host eggs attached to cards, and (2) a hand-held leafblower distributing parasitized eggs in bulk. Neither technique affected the emergence of the parasitoids released. Parasitoids emerging from eggs released in bulk had a similar sex ratio, longevity, and fecundity to those not released. Both methods of ground release achieved uniform parasitoid distribution and resulted in levels of parasitism similar to those achieved with aerial releases. Parasitism was greater in the mid- to upper canopy of trees than in the lower canopy. The difficulties associated with each technique and its comparative usefulness in experimental and operational programs are discussed.

Full textAbstract:
The aim of this work was to determine contents and turnover rates for dopamine (DA) and norepinephrine (NE) and to identify the catecholamine (CA) released during stimulation of the rat carotid body (CB). Turnover rates and the release of CA were measured in an in vitro preparation using a combination of HPLC and radioisotopic methods. Mean rat CB levels of DA and NE were 209 and 45 pmol/mg tissue, respectively. With [3H]tyrosine as precursor, rat CB synthesized [3H]CA in a time- and concentration-dependent manner; calculated turnover times for DA and NE were 5.77 and 11.4 h, respectively. Hypoxia and dibutyryl adenosine 3′,5′-cyclic monophosphate significantly increased [3H]CA synthesis. In normoxia, rat CB released [3H]DA and [3H]NE in a ratio of 5:1, comparable to that of the endogenous tissue CA. Hypoxia and high K+ preferentially released [3H]DA, nicotine preferentially released [3H]NE, and acidic stimuli released both amines in proportion to tissue content. Release of [3H]CA induced by hypoxia and high K+ was nearly fully dependent on extracellular Ca2+, whereas basal normoxic release was not altered by removal of Ca2+ from the incubating solution. We conclude that the rat CB is an organ with higher levels of DA than NE that preferentially releases DA or NE in a stimulus-specific manner.

Full textAbstract:
The fall migration of monarch butterflies, Danaus plexippus (L.), in the Pacific Northwest was studied during 2017–2019 by tagging 14,040 captive-reared and 450 wild monarchs. One hundred and twenty-two captive-reared monarchs (0.87%) were recovered at distances averaging 899.9 ± 98.6 km for Washington-released and 630.5 ± 19.9 km for Oregon-released monarchs. The greatest straight-line release to recovery distance was 1392.1 km. A mean travel rate of 20.7 ± 2.2 km/day and maximum travel of 46.1 km/day were recorded. Recovery rates were greater for Oregon-released monarchs (0.92%) than Washington-released (0.34%) or Idaho-released monarchs (0.30%). Most monarchs (106/122) were recovered SSW-S-SSE in California, with 82 at 18 coastal overwintering sites. Two migrants from Oregon were recovered just weeks after release ovipositing in Santa Barbara and Palo Alto, CA. Two migrants released in central Washington recovered up to 360.0 km to the SE, and recoveries from Idaho releases to the S and SE suggests that some Pacific Northwest migrants fly to an alternative overwintering destination. Monarchs released in southern Oregon into smoky, poor quality air appeared to be as successful at reaching overwintering sites and apparently lived just as long as monarchs released into non-smoky, good quality air. Migration and lifespan for monarchs infected with the protozoan parasite, Ophryocystis elektroscirrha (McLaughlin and Myers), appeared to be similar to the migration and survival of uninfected monarchs, although data are limited. Our data improve our understanding of western monarch migration, serving as a basis for further studies and providing information for conservation planning.

"Redox control of surface protein sulphhydryls in bovine spermatozoa reversibly modulates sperm adhesion to the oviductal epithelium and capacitation." REPRODUCTION 138, no. 1 (2009): 33–43. http://dx.doi.org/10.1530/rep-08-0514.
Full textAbstract:
Oviductal fluid molecules, such as sulphated glycosaminoglycans and disulphide-reductants, may represent periovulatory signals for the release of spermatozoa from the oviductal reservoir in the bovine species. Disulphide-reductants release spermatozoa through the reduction of sperm-surface disulphides to sulphhydryls (SH). Herein, we studied sperm-surface protein SH through labelling with maleimidylpropionyl biocytin in the initial sperm suspension, in the subpopulations able and unable to adhere to the in vitro cultured oviductal epithelium, and in spermatozoa released either through the disulphide-reductant penicillamine (PEN) or the sulphated glycosaminoglycan heparin (HEP). Adhesion assays were performed to study the ability of released spermatozoa to readhere to the oviductal epithelium. Results showed that the level of SH in sperm-surface proteins was: 1) low in adhering spermatozoa; 2) high in spermatozoa unable to adhere; and 3) markedly increased in released spermatozoa. Adhesion assays showed that: 1) PEN-released spermatozoa promptly recovered adhesion after removal of the disulphide-reductant and could be released again in response to PEN; 2) conversely, a limited number of HEP-released spermatozoa was able to readhere to the oviductal epithelium and this ability was not affected by HEP removal. Recovery of adhesion was associated to reoxidation of sperm-surface protein SH and to the reversal of capacitation. In conclusion, redox modulation of sperm-surface protein SH is involved in the release of spermatozoa adhering to the oviduct in vitro; the reversible action of disulphide-reductants might be responsible for intermittent phases of adhesions and releases; and the irreversible action of HEP indicates that it may represent a terminal releasing signal.

Full textAbstract:
Abstract The abilities of recombinant human interleukin 1 (IL-1) and IL-6 to induce release of FSH, LH and PRL from rat pituitary cells in vitro were examined. IL-1 and IL-6 induced significant releases of FSH, LH and PRL within 3 h. The extents of release of these compounds induced by IL-1 and IL-6 were similar to those induced by GnRH and TRH. Rat anterior pituitary cells released IL-6 spontaneously, and its release was enhanced by IL-1β. This effect of IL-1β was inhibited significantly by a rabbit anti-IL-1β antiserum. These findings suggest that IL-1 induced the release of IL-6 from rat pituitary, and that the released IL-6 stimulated the secretions of FSH, LH and PRL.

Full textAbstract:
Sterile males of Aedes aegypti were released once a week for 8 weeks to evaluate the dispersal efficiency of ground and aerial drone release methods in a rural village of 26 Ha in southern Mexico. Indoor and outdoor BG-Sentinel traps were placed in 13–16 houses distributed throughout the village. The BG traps were activated 48 h after the release of the sterile males and functioned for a 24 h period following each release. Over the 8-week period of simultaneous ground and aerial releases, an average of 85,117 ± 6457 sterile males/week were released at ground level and 86,724 ± 6474 sterile males/week were released using an aerial drone. The ground release method resulted in higher numbers of captured males (mean = 5.1 ± 1.4, range 1.1–15.7 sterile males/trap) compared with the aerial release method (mean = 2.6 ± 0.8, range 0.5–7.3 sterile males/trap) (p < 0.05). Similarly, the prevalence of traps that captured at least one sterile male was significantly higher for ground release compared to the aerial release method (p < 0.01). The lower numbers of sterile males captured in the aerial release method could be due to mortality or physical injury caused by the chilling process for immobilization, or the compaction of these insects during transport and release. However, aerial releases by a two-person team distributed insects over the entire village in just 20 min, compared to ~90 min of work for a five-person team during the ground release method. Ground release also resulted in higher aggregations of males and some villagers reported feeling discomfort from the presence of large numbers of mosquitoes in and around their houses. We conclude that modifications to the handling and transport of sterile males and the design of containers used to store males are required to avoid injury and to improve the efficiency of aerial releases for area-wide SIT-based population suppression programs targeted at mosquito vectors of human disease.

Full textAbstract:
The current work presents the preliminary results of the Cinereous Vulture (<i>Aegypius monachus</i>) releases in the Balkan Mountains in 2018–2022, aiming at the species re-introduction in Bulgaria, where it was listed as locally extinct since 1985. The first imports and releases of Cinereous Vultures in Bulgaria started in 2018. Until mid-2022, 72 individuals were released in the Eastern Balkan Mountains (Kotlenska Planina SPA and Sinite Kamani Nature Park) and Vrachanski Balkan Nature Park. Of them, 63 immatures imported from Spain were released from aviaries and nine juveniles captive-bred in European zoos were released by hacking (fledging from an artificial nest). We compared the success in survival and establishment between the different release sites and methods used to adjust the ongoing technics and tactics and to support knowledge improvement for future similar projects.From the nine Cinereous Vultures released by hacking, the results were as follows: 1.00 fledging success, but only 0.22 survival in the first six months – combined period of acclimation, first migration and the first winter. All survivors from that period reached maturity into the wild, but all emigrated from the release site and settled elsewhere.Of the 63 individuals released by aviaries, 32 individuals were released in the Eastern Balkan Mountains (18 individuals are still alive – 0.56 survival; 14 individuals settled in the area, which accounts for 0.44 of all released birds and 0.78 of the survivors). Thirty-one individuals were released in Vrachanski Balkan Nature Park (23 individuals are still alive – 0.74 survival; 22 individuals settled in the area – 0.71 of all released birds and 0.96 of the survivors). Based only on aviary method comparison, the settling of the individuals in the release area was alike in the two sites. However, the Vrachanski Balkan Nature Park performed better in survival – both in acclimation and establishment periods.While comparing the release methods – hacking and release from the aviary – the following results were observed: the survival rate during acclimation was 0.86. Due to more considerable losses during the first migration and dispersal in the individuals released by hacking, the survival rate of 0.22 was significantly lower compared to 0.73 for the birds released from the aviary. Additionally, in both methods, a similar pattern in the first winter and spring migration dispersal was observed. Although the survival was equal in the released-by-hacking or aviary birds after the first year onwards, it is essential to note that the emigration of the hacked birds from the release site was 1.00. In comparison, the birds released from aviaries largely remained and settled in the release area (> 0.77 of the survivors). The cost of release and related acclimation, settling, dispersal and the first winter was the greatest: 0.12–0.17 per period, or cumulatively, it was about 0.27. Survival increased and stabilised to > 0.90 after the first year in the wild and reached nearly 1.00 after two years in the wild onwards.Two distinct nuclei of the Cinereous Vulture were established along the Balkan Mountains – the Eastern Balkan Mountains with 18–23 individuals and four formed pairs using a territory of about 642.74 km<sup>2</sup> – 95% home range and 85.72 km<sup>2</sup> – 50% core area with center being the town of Kotel; and Vrachanski Balkan Nature Park with present 23–29 individuals, of which 2–3 pairs formed so far, using a territory of about 1,143.66 km<sup>2</sup> – 95% home range and 22.89 km<sup>2</sup> – 50% core area with center being the village of Zgorigrad. The species readily accepted breeding in artificial nest platforms built by professional arborists on different tree species – oak, beech, sycamore and pine. The only naturally built nests were on the ground (n = 2) (unsuccessful) and in Scots Pine (n = 1) (successful). In 2021 and 2022, in each of the two sites, the first successful reproductions were recorded, which marked the return of the Cinereous Vulture as breeding species – 28 years after the last occasional record of a single breeding pair in the country and 36 years after it was officially listed as locally extinct in Bulgaria.

Full textAbstract:
In late April of 1983, 1984, and 1985, 140 000 marked chinook salmon (Oncorhynchus tshawytscha) smolts (2–4 g) were transported by helicopter from Quinsam Hatchery to four release sites near Campbell River, B.C. (river, estuarine, transition, and marine), in an experiment to test the importance of estuarine residency to chinook survival. At the marine site, fish were released directly into seawater. These fish had high cortisol levels and larger interrenal nuclear diameters than those at the estuarine site, indicating a transitory stress response to seawater exposure. Nevertheless, there was little direct mortality due to stress or osmoregulatory shock at any of the release sites. Marine-released fish were exposed to more bird and fish predators. Mortality of caged chinook was higher at the marine location than at all other sites despite seawater challenge tests indicating that the chinook were smolted and "ready for sea." Beach seine data obtained biweekly for 4 mo after the releases showed that fish released directly into marine waters rarely dispersed to the Campbell River estuary. Fish released immediately adjacent to the mouth of the estuary (transition zone) had the widest immediate dispersal pattern, with many of them returning to the estuary. Estuarine zone fish displayed the most restricted distribution. Fish released to the river and estuary remained in the sampling area for a longer period (34–47 d) than those released in the marine or transition zone (20–23 d).

We describe two classes of software systems that release tabular summaries of an underlying database. Table servers respond to user queries for (marginal) sub-tables of the "full" table summarizing the entire database, and are characterized by dynamic assessment of disclosure risk, in light of previously answered queries. Optimal tabular releases are static releases of sets of sub-tables that are characterized by maximizing the amount of information released, as given by a measure of data utility, subject to a constraint on disclosure risk. Underlying abstractions — primarily associated with the query space, as well as released and unreleasable sub-tables and frontiers, computational algorithms and issues, especially scalability, and prototype software implementations are discussed.

AbstractThe mealybug Phenacoccus herreni Cox & Williams causes considerable damage to cassava Manihot esculenta Crantz. Field surveys conducted between 1988 and 1994 indicated the mealybug was present in 57 municipalities in six States in north-eastern Brazil, in some places reaching high levels of infestation. Several native natural enemy species were found associated with the pest in Brazil. Exotic encyrtid parasitoids were imported and released in fields in the States of Bahia and Pernambuco. Apoanagyrus diversicornis (Howard) was introduced from Colombia, and Acerophagus coccois Smith, and Aenasius vexans (Kerrich) were introduced from Venezuela. By the end of 1996, a total of 35,930 parasitoids had been released. In Bahia, Apoanagyrus diversicornis was recovered 130, 234, 304 and 550 km from its release site after 6, 14, 21 and 33 months, respectively. Acerophagus coccois was recovered at 180 km from its release site nine months after release. Aenasius vexans, however, did not disperse at all despite being consistently recovered at its release site. In Pernambuco, 9010 parasitoids were released from October, 1995 onwards. Acerophagus coccois and Aenasius vexans were recovered up to 40 km from the release sites after three and five months of their initial releases, respectively. The establishment and dispersal of these parasitoids are discussed.

Full textAbstract:
The success of phytoseiid mite releases to control spider mites [Eotetranychus carpini (Oudemans) and Panonychus ulmi (Koch)] on grapevines can be influenced by pesticide use and competition with local predatory mites. In field experiments we evaluated the effect of the release of Kampimodromus aberrans (Oudemans) and Typhlodromus pyri Scheuten strains showing field resistance to organophosphates and dithiocarbamates. Predatory mites were released in two vineyards infested by spider mites despite the occurrence of Amblyseius andersoni (Chant) and/or Phytoseius finitimus Ribaga. Single or mixed releases were planned. Spider mite populations were not effectively controlled by local predatory mites while successful control was achieved by released species. The effects of releases were higher in the second experimental year. In most cases A. andersoni densities were reduced by T. pyri and K. aberrans releases. Ph. finitimus suffered less than A. andersoni from intraguild predation. Among released species, the effect of the presence of a competitor was higher on T. pyri than on K. aberrans. Results suggest that the outcome of intraguild predation is prey-mediated. The equilibrium level between K. aberrans and T. pyri may depend on which spider mite species is the shared prey. The implications in management of spider mites on grapevines are discussed.

Full textAbstract:
Release rates at 21 °C were determined in sand columns for 12 commercially available soluble and controlled-release Mg fertilizers. Lutz Mg spikes, K2SO4, MgSO4, MgSO4·H2O, and MgSO4·7H2O released their Mg within 2 to 3 weeks. Within the first 6 weeks, MgO·MgSO4 released its soluble Mg fraction, but little release occurred thereafter. Dolomite and MgO released <5% of their Mg over 2 years while MagAmp released <20% of its Mg. Florikan 1N-0P-26K-4Mg types 100 and 180 exhibited typical controlled-release fertilizer characteristics, with most of their Mg release occurring during the first 15 weeks.

Full textAbstract:
Abstract Mark-recapture experiments were conducted in the tidal Nanticoke River (Chesapeake Bay) to determine how the salt front retains striped bass larvae and controls nursery production. During two spring spawning seasons, 25.1 million hatchery-produced, first-feeding larvae (5–12 days post-hatch) were released with chemically marked otoliths at selected locations and times. Surveys tracked the spatial and demographic fates of released and naturally spawned larvae. Released larvae dispersed rapidly within the freshwater tidal portion of the estuary and were retained above the salt front. Their distributions overlapped with natural larvae. Growth and mortality rates did not differ with respect to release location, but did vary with day of release, influenced by storm events and seasonal changes in temperature. In 1993, a group released during a storm event did not yield any recaptured larvae. Zooplankton concentrations in both years were likely sufficient for successful larval feeding. In spring 1993, a season of relatively high freshwater flow, nursery volume was 2.1-fold larger and juvenile production from larval releases was fourfold higher than in 1992. We propose that increased nursery volume reduces variance in water quality, enhances retention of larvae within the nursery, thus increasing production of larval striped bass.

Nickel-titanium archwires in orthodontic wires have nickel ion releases. The use toothpaste and saliva immersion time may cause its releases. This study aims to prove the difference and interaction between immersion time and toothpaste variations towards the amount of nickel ion releases at nickel-titanium archwires. The study was an experimental research with a post-test only control group design. Twenty seven nickel-titanium archwires were divided into three groups, i.e., K group, which were immersed in artificial saliva. P1 was immersed in artificial saliva and 1.5 gram of toothpaste A, and P2 was immersed in artificial saliva, and 1.5 gram of toothpaste B. The samples were incubated (37 °C) for 1 and 1.5 months. Nickel ion released was analyzed using SSA. Two Way ANOVA and Post Hoc LSD test were the statistic test used. The results of this study were the K group which released 0.112 mg/l and 0.685 mg/l, P1 which released 0.093 mg/l and 0.670 mg/l, and P2 which released 0.099 mg/l and 0.657 mg/l. There were differences in toothpaste variations (p = 0.029), differences in immersion time (p = 0.000) and there was no interaction between immersion time and toothpaste variations (p = 0.505) on the amount of nickel ion release. There was a significant difference in K-P1 (p = 0.038), K-P2 (p = 0.013), P1-P2 (p = 0.049). There was a difference in immersion time and toothpaste variation, but there was no interaction between immersion time and toothpaste variation towards the amount of nickel ion releases.

Full textAbstract:
ABSTRACTLeaching tests were carried out in aerobic and anaerobic conditions to assess the 14C released from TRIGA irradiated graphite. Both total 14C and inorganic and organic fractions in the leachant solutions were measured. The experimental results obtained from the leaching tests confirm the low 14C release rate in alkaline environment. Less than 2% of the total 14C inventory in the specimens subject to the leaching tests was released as dissolved species. Both inorganic and organic 14C species are released in alkaline conditions, with more inorganic 14C release under aerobic conditions (around 68% of the total 14C released was released as inorganic dissolved species), and more organic 14C species in anaerobic conditions (around 65% of the total 14C released was released as organic dissolved species). Both for anaerobic and aerobic conditions, the leaching rates are high in the first days of immersion and decrease after that, indicating a two stage process: an initial quick release (less than 9 × 10–02 % of inventory/day for the first 48 days) followed by a slower release rate (around 4 × 10–03 % of inventory/day).

Full textAbstract:
The reintroduction of missing mammal species in former habitats has recently been of high interest. In Mexico, there have been several attempts to reintroduce Antilocapra since 1967, but until now none of the trials has been successful. Nowadays, different releasing methods have been practiced for mammal species, including soft and hard release ones. The aim of this study was to provide new information, and to evaluate the success of a recent release. The study was based on the monitoring of 100 individuals (70 females, 30 males) captured in New Mexico, USA, to be released in Maderas del Carmen, Coahuila, Mexico, in two different groups. The first group (fast release) of 45 specimens (20 females, 25 males) was released in the valley at the beginning of March 2009. The second one (soft release), with 55 individuals (50 female, 5 male), was released in March 2010. For both groups, we compared the mortality rate between dispersal and soft-release vs. hard-release methods. Our results showed that the release with adaptation gave highly significant results (χ2= 2, α= 0.05, p= 0.0001)). The comparison of mortality and dispersion among both methods was highly contrasting: with soft-release we obtained 4 % and 13 % of success, against 23 % and 46 %, respectively. Considering these results, we recommend the soft-release method to be used in future reintroduction attempts of Antilocapra, since more than 50 % of specimens from hard-releases died because of capture stress, or were dispersed, and thus reduced the reintroduction success chances.

The phytase enzyme was collected from plants (cereal, legumes and oilseeds) and fungal sources and compared their efficiency to release inorganic P from organic P compounds. In general, fungi released more phytase after 21 days of growth and their extracellular activity was more than their intra-cellular counterpart. Plants are releasing 4 to 43% more phytase under P deficient condition as compared to the sufficient P condition. Oilseed crops releases higher phytase than legumes and cereal crops. But phytase released from legumes are discovered to be more efficient to hydrolyze organic phosphorus. Phytase release by Chaetomium globosum was exposed to be most efficient on as compared to the phytase produced by other tested fungi. Phytase originated from fungal sources are described to be more efficient than similar amount of phytase originated from plant sources.

Full textAbstract:
ABSTRACTRadiocarbon (14C or carbon-14, half-life 5730 yr) is a key radionuclide in the assessment of the safety of a geological disposal facility (GDF) for radioactive waste. In particular, the radiological impact of gaseous carbon-14 bearing species has been recognized as a potential issue. Irradiated steels are one of the main sources of carbon-14 in the United Kingdom’s radioactive waste inventory. However, there is considerable uncertainty about the chemical form(s) in which the carbon-14 will be released. The objective of the work was to measure the rate and speciation of carbon-14 release from irradiated 316L(N) stainless steel on leaching under high-pH anoxic conditions, representative of a cement-based near field for low-heat generating wastes. Periodic measurements of carbon-14 releases to both the gas phase and to solution were made in duplicate experiments over a period of up to 417 days. An initial fast release of carbon-14 from the surface of the steel is observed during the first week of leaching, followed by a drop in the rate of release at longer times. Carbon-14 is released primarily to the solution phase with differing fractions released to the gas phase in the two experiments: about 1% of the total release in one and 6% in the other. The predominant dissolved carbon-14 releases are in inorganic form (as 14C-carbonate) but also include organic species. The predominant gas-phase species are hydrocarbons with a smaller fraction of 14CO (which may include some volatile oxygen-containing carbon-species). The experiments are continuing, with final sampling and termination planned after leaching for a total of two years.

Significantly less glucuronoxylomannan (GXM) was released by C. neoformans in the presence of capsule-binding monoclonal antibody (MAb). MAb-mediated inhibition of GXM release may be another mechanism by which humoral immunity can mediate protection against this pathogen.

Full textAbstract:
Ranching, stock enhancement and restocking are management approaches involving the release of wild or hatchery-bred organisms to enhance, conserve or restore fisheries. The present study, conducted from April 2002 to November 2005, evaluated the effectiveness of releasing wild and hatchery-reared (HR) mud crabs in the mangroves of Ibajay, Aklan, Philippines where preliminary studies demonstrated declining fishery yields, abundance and size of crabs. Comparison of survival and growth of wild-released and HR Scylla olivacea and HR Scylla serrata demonstrated the effect of nursery conditioning, size-at-release and species differences. Overall yield and catch per unit effort (CPUE) increased by 46% after stock enhancement trials. Recapture rates of released crabs were highest in wild-released S. olivacea and in crabs measuring 65.0–69.9 mm carapace width (CW) and lowest in non-conditioned HR S. serrata. Growth rates were highest for conditioned HR S. olivacea and lowest for conditioned HR S. serrata (11.7 and 3.7 mm month–1 respectively). Fishing mortality was highest for S. olivacea, whereas natural mortality was greater for S. serrata. Conditioning hatchery-bred animals before release is also important in obtaining higher survival. S. olivacea was the more appropriate of the two species for release in mangrove habitats inundated with low-salinity water. However, there is a need for site-specific studies to evaluate the effectiveness of releases.

Full textAbstract:
Deer species (fallow, red, sambar, chital, rusa and hog deer) have formed wild populations in Australian habitats ranging from arid woodland to rainforest and are a growing management issue. Data were obtained via an Australia-wide land-manager survey that collected information on the liberation, distribution, abundance and management of wild deer in Australia. It is estimated that there are 218 wild deer herds in Australia with 7% of these herds originating from acclimatisation society releases, 35% from deer farm escapes/releases and 58% from translocations (deliberate releases). On average, herds released by acclimatisation societies are estimated to be 107 years old, herds that have escaped from (or been released from) deer farms are 9 years old, and transplanted herds are 6 years old. It is estimated that Australia currently has 200 000 wild deer, with 85% of these deer originally released by acclimatisation societies, 6% through escapes/releases from deer farms and 9% by translocation. Poor knowledge of the impacts of wild deer by land managers and the absence of consistent legislation governing the management of farmed and wild deer are factors that have exacerbated deliberate releases of deer and the escape of deer from farms. Management strategies for wild deer in Australia need to be developed by land managers to address the escape and release of deer from farms, the illegal translocation of deer into the wild and the management of existing wild deer herds.

Full textAbstract:
We describe efforts to reintroduce the extinct-in-the-wild Spix’s Macaw (Cyanopsitta spixii) within its historical range in eastern Brazil. Twenty captive-reared Spix’s Macaws were released, along with 15 Blue-Winged Macaws (Primolius maracana), as heterospecific flocks in two events during the dry and rainy seasons of 2022. We monitored the release groups through daily observation and telemetry tracking from early June 2022 to early June 2023. We documented an overall first-year survival of 58.3% (CI: 37.8–78.7%), with 65% of Spix’s Macaws establishing a stable area of activity within 5 km of the release site, excluding any temporary long-distance forays. Eighty-five percent of released Spix’s Macaws exhibited flock cohesion, including interactions with and integration into wild Blue-Winged Macaw groups at the release site. Several released Spix’s Macaws formed pair-bonds with conspecifics and engaged in nest cavity exploration, breeding behavior, and territorial defense of nest sites, with three females also laying and incubating eggs. One nesting pair successfully hatched and reared chicks in an artificial nest cavity. These releases employed a novel reintroduction strategy using a surrogate species model, the sympatric Blue-Winged Macaw, to “mentor” and facilitate post-release adaptation by the target species and increase the total number of individuals in the release cohort. Lastly, participatory monitoring by local citizens is considered a way to engage and involve local communities in species and habitat conservation and potentially create new employment opportunities in the region.

Full textAbstract:
The codling moth is a serious pest of apples in most regions of the world where this fruit is produced. The sterile insect technique is one strategy used to control this pest and is employed as part of an area-wide integrated pest management program for the codling moth in British Columbia, Canada. Modified fixed wing aircraft are the most common method for the release of sterile insects in large area-wide pest management programs. However, aerial release with a full-size aircraft can be prohibitively expensive. We evaluated the use of small, uncrewed aircraft systems (UASs) for the release of sterile codling moths. Sterile codling moths released from greater altitudes were more broadly distributed and drifted more in strong winds, compared to those released from lower altitudes. Most of the released insects were recaptured in a 50 m wide swath under the release route. Recapture rates for aerially released insects were 40–70% higher compared to those released from the ground. UASs provide a promising alternative to ground release and conventional aircraft for the release of sterile codling moths.

Full textAbstract:
In 1981 Carlintagged Atlantic salmon smolts from the river Imsa and river Sandvikselv stocks, and in 1984 smolts from the river Loneelv stock were released in the river Akerselv. The smolts left the river and the inner Oslofjord few weeks after release. Most adult recaptures were reported from the sea fisheries. Adults from the Imsa and Sandvikselv stocks were caught in more distant waters than fish from the Loneelv stock. The main reason for this is probably due to size selective fishery. Straying to neighbouring rivers in Oslojord was very common, especially for the smolts released in 1981. The Loneelv smolts released in 1984 gave the best adult return to the river Akerselv. It is concluded that smolt releases in the river Akerselv particularly of a grilse stock like that of the river Loneelv may be a useful way to develop a recreational fishery in the Oslofjord and the river Akerselv.

Full textAbstract:
Because the surface of MDF is not aesthetically pleasing, it usually needs to be veneered and then painted, but such a board releases harmful VOCs, among which Benzene Series is the most harmful. Benzene and its series are a group of carcinogenic compounds. With the diluents of nitrocellulose (NC)-lacquered MDF as the research objects, the release of the Benzene Series was studied to provide a scientific basis for pollution control and a reference for eco-friendly paint production. The attenuant of NC paint, anhydrous ethanol, ethyl acetate and solvents mixed with different alcohol ester ratios were used as diluents in NC lacquer. Two kinds of wood-veneered MDF with different thickness (18 mm and 8 mm) were coated with NC lacquer and analyzed in the experiment. The gas was collected using a small environmental chamber and the Benzene Series was analyzed using GC-MS. The concentration of Benzene Series released by MDF was 316.24 μg·m−3, and that of the NC-lacquered MDF with thicknesses of 18 mm and 8 mm were 284.44 μg·m−3 and 281.06 μg·m−3, respectively. The MDF released 14 kinds of Benzene Series, and the NC-lacquered MDF with two thicknesses released 18 kinds of it. The release concentration order of Benzene Series in NC-lacquered MDF with different diluents of the 18 mm thick panel was NC-M, NC-A, and NC-E from high to low. The lowest concentration of it occurred when the ratio of anhydrous ethanol to ethyl acetate was 1:3, and the lowest amount of components were at the ratio of 1:2. The concentration of Benzene Series released by MDF is higher than that released by the NC-lacquered MDF. Thickness has no effect on the type of release. The thicker MDF was, the higher the concentration was. The alcohol and ester thinner can control the release of Benzene Series from the source, and the optimal mixing ratio was 1:3.

Full textAbstract:
ABSTRACT It has been suggested that the antibiotic-induced release of lipopolysaccharide (LPS) is an important cause of the development of septic shock in patients treated for severe infections caused by gram-negative bacteria. β-Lactam antibiotics change the integrity of the bacterial cell envelope by binding to penicillin-binding proteins (PBP) in the membrane and thus may affect the amount of LPS that is released and the kinetics of that release. In this respect, ceftazidime at intermediate concentrations binds with a high affinity to PBP 3 and PBP 1a and thus can induce filament formation in addition to killing, whereas imipenem preferentially binds to PBP 2 and PBP 1b, leading to spheroplast formation and rapid cell lysis. We investigated the effects of these antibiotics on the killing and the release of the radioactively labelled LPS of Salmonella typhi Ty 21A. A mathematical model was developed to calculate the delay between bacterial killing and LPS release, designated the lag time. At antibiotic concentrations inducing equal killing, the amount of LPS released was the same for both antibiotics. Only after 6 h of incubation at antibiotic concentrations above 0.5 μg/ml, the amount of 3H-LPS released was slightly higher (∼1.2-fold) in incubations with ceftazidime than in those with imipenem, and the maximum releases of the total label were 33.2% ± 0.89% and 27.1% ± 0.45%, respectively. Despite the clear concentration-dependent effect on the bacterial killing and subsequent LPS release, the lag time was independent of the antibiotic concentration. For ceftazidime as well as imipenem the lag time amounted to approximately 60 min. In conclusion, our findings imply that the mechanism of antibiotic-induced LPS release is independent of the PBP affinities for these β-lactam antibiotics. Furthermore, once the organism is killed by either imipenem or ceftazidime, the rate of LPS release from S. typhi does not differ according to the antibiotic with which the organism is killed, and there is little difference in the relative amount of LPS released.

AbstractWe studied the effects of inundative releases of the egg parasitoid Trichogramma minutum Riley (Hymenoptera: Trichogrammatidae) on economic injury by grape berry moth, Endopiza viteana (Clemens) (Lepidoptera: Tortricidae). Trichogramma minutum originally collected from natural host populations near North East, Pennsylvania, was mass produced in tobacco hornworm hosts and Mediterranean flour moth. We released T. minutum in border rows, where grape berry moth infestation is typically high, of experiment field station and commercial vineyards from 1996 to 1999. We recorded significant reductions in economic injury in plots where parasitoids were released. In vineyards with low to moderate grape berry moth abundance, four releases during the growing season were adequate in reducing damage at harvest to below 3%. In high-risk vineyards, T. minutum releases reduced damage to levels below 15%. The use of buckwheat as a cover crop to provide nectar in combination with parasitoid releases showed potential benefits in parasitoid activity. A biocarrier and Biosprayer™ were used in mechanized parasitoid-release operations, and no adverse effect on parasitoid emergence was recorded from parasitized eggs using this approach.

Abstract This paper documents the seventeenth data release (DR17) from the Sloan Digital Sky Surveys; the fifth and final release from the fourth phase (SDSS-IV). DR17 contains the complete release of the Mapping Nearby Galaxies at Apache Point Observatory (MaNGA) survey, which reached its goal of surveying over 10,000 nearby galaxies. The complete release of the MaNGA Stellar Library accompanies this data, providing observations of almost 30,000 stars through the MaNGA instrument during bright time. DR17 also contains the complete release of the Apache Point Observatory Galactic Evolution Experiment 2 survey that publicly releases infrared spectra of over 650,000 stars. The main sample from the Extended Baryon Oscillation Spectroscopic Survey (eBOSS), as well as the subsurvey Time Domain Spectroscopic Survey data were fully released in DR16. New single-fiber optical spectroscopy released in DR17 is from the SPectroscipic IDentification of ERosita Survey subsurvey and the eBOSS-RM program.

Full textAbstract:
Estimates of growth rates in early ocean life and length frequency distributions at time of release for adult survivors were inferred from scale measurements for lots of coho salmon (Oncorhynchus kisutch) released at several dates from a Columbia River hatchery (Big Creek) and a southern Oregon hatchery (Coos Bay). Analysis of these measurements failed to support either of two literature-suggested hypotheses for the variability of marine survival of hatchery coho by date of release: (1) intraseasonal variability of food supply during early marine life; and (2) intraseasonally improving ability of smaller individuals within release lots to convert to salt water. Marine survival improved substantially with date of release at both hatcheries. However, fish released earliest, which survived relatively poorly, grew as fast in early marine life as fish released later, which survived better. Thus, poor survival of the early released fish did not appear related to lack of food at early ocean life. For the Big Creek hatchery, no significant differences were seen between the mean lengths at date of release and the mean release-date lengths of adult survivors back calculated from their scales, for lots released on May 5, June 3, and July 2. Apparently, small and large fish of each lot survived with equal probability. For the Coos Bay hatchery, the mean release-date lengths of adult survivors were significantly larger than the mean lengths of all fish released, for each of six lots released between early June and late July. Thus, large fish apparently survived better than small ones within each of these six lots. But there was no seasonal trend in survivability of small fish relative to large ones, contrary to hypothesis (2)

Full textAbstract:
The pancreatic B cell has been used as a model to compare the release of newly synthesized prohormone/hormone with that of stored hormone. Secretion of newly synthesized proinsulin/insulin (labeled with [3H]leucine during a 5-min pulse) and stored total immunoreactive insulin was monitored from isolated rat pancreatic islets at basal and stimulatory glucose concentrations over 180 min. By 180 min, 15% of the islet content of stored insulin was released at 16.7 mM glucose compared with 2% at 2.8 mM glucose. After a 30-min lag period, release of newly synthesized (labeled) proinsulin and insulin was detected; from 60 min onwards this release was stimulated up to 11-fold by 16.7 mM glucose. At 180 min, 60% of the initial islet content of labeled proinsulin was released at 16.7 mM glucose and 6% at 2.8 mM glucose. Specific radioactivity of the released newly synthesized hormone relative to that of material in islets indicated its preferential release. A similar degree of isotopic enrichment of released, labeled products was observed at both glucose concentrations. Quantitative HPLC analysis of labeled products indicated that glucose had no effect on intracellular proinsulin to insulin conversion; release of both newly synthesized proinsulin and insulin was sensitive to glucose stimulation; 90% of the newly synthesized hormone was released as insulin; and only 0.5% of proinsulin was rapidly released (between 30 and 60 min) in a glucose-independent fashion. It is thus concluded that the major portion of released hormone, whether old or new, processed or unprocessed, is directed through the regulated pathway, and therefore the small (less than 1%) amount released via a constitutive pathway cannot explain the preferential release of newly formed products from the B cell.

Full textAbstract:
ABSTRACTNeisseria gonorrhoeae(gonococci) andNeisseria meningitidis(meningococci) are human pathogens that cause gonorrhea and meningococcal meningitis, respectively. BothN. gonorrhoeaeandN. meningitidisrelease a number of small peptidoglycan (PG) fragments, including proinflammatory PG monomers, althoughN. meningitidisreleases fewer PG monomers. The PG fragments released byN. gonorrhoeaeandN. meningitidisare generated in the periplasm during cell wall remodeling, and a majority of these fragments are transported into the cytoplasm by an inner membrane permease, AmpG; however, a portion of the PG fragments are released into the extracellular environment through unknown mechanisms. We previously reported that the expression of meningococcalampGinN. gonorrhoeaereduced PG monomer release by gonococci. This finding suggested that the efficiency of AmpG-mediated PG fragment recycling regulates the amount of PG fragments released into the extracellular milieu. We determined that three AmpG residues near the C-terminal end of the protein modulate AmpG's efficiency. We also investigated the association between PG fragment recycling and release in two species of human-associated nonpathogenicNeisseria:N. siccaandN. mucosa. BothN. siccaandN. mucosarelease lower levels of PG fragments and are more efficient at recycling PG fragments thanN. gonorrhoeae. Our results suggest thatN. gonorrhoeaehas evolved to increase the amounts of toxic PG fragments released by reducing its PG recycling efficiency.IMPORTANCENeisseria gonorrhoeaeandNeisseria meningitidisare human pathogens that cause highly inflammatory diseases, althoughN. meningitidisis also frequently found as a normal member of the nasopharyngeal microbiota. NonpathogenicNeisseria, such asN. siccaandN. mucosa, also colonize the nasopharynx without causing disease. Although all four species release peptidoglycan fragments,N. gonorrhoeaeis the least efficient at recycling and releases the largest amount of proinflammatory peptidoglycan monomers, partly due to differences in the recycling permease AmpG. Studying the interplay between bacterial physiology (peptidoglycan metabolism) and pathogenesis (release of toxic monomers) leads to an increased understanding of how different bacterial species maintain asymptomatic colonization or cause disease and may contribute to efforts to mitigate disease.

Full textAbstract:
We have studied the effects of 2,3-butanedione monoxime (BDM) on the sarcoplasmic reticulum (SR) of saponin-treated rat cardiac trabeculae. Rapid application of 20 mM caffeine released Ca2+ from the SR, which was detected using the fluorescent Ca2+ indicator indo 1. The amplitude of the caffeine-induced Ca2+ transient was used as an index of the Ca2+ content of the SR before, during, and after exposure to various concentrations of BDM. BDM (1-5 mM) had little effect on caffeine-induced Ca2+ release. At these levels of BDM, force was inhibited predominantly by a direct action of BDM on the myofilaments. However, with higher concentrations (5-30 mM), BDM caused a concentration-dependent decrease in the amount of Ca2+ released from the SR in response to caffeine. This action of BDM may contribute to the negative inotropic effect of the drug in intact cardiac preparations by reducing the amount of Ca2+ available for release during systole. Rapid application of BDM induced a net release of Ca2+ from the SR. Both BDM and caffeine-induced Ca2+ releases were abolished following treatment of the muscle with 10 microM ryanodine. BDM failed to release Ca2+ in the absence of ATP or after substitution of ATP with nonhydrolyzable adenine nucleotides. In contrast, caffeine released Ca2+ in the absence of ATP. The possible involvement of the Ca(2+)-uptake pump in the action of BDM on the SR is discussed.

Full textAbstract:
In all cells, generation and release of specific vesicles are the initial steps of back-and-forth intercellular communication. These processes are critical in normal physiology and pathophysiology. Vesicles have particular functions appropriate to their targets. When stimulated, they are released into the extracellular space. Four cytoplasmic membrane-bound structures generate their particular vesicles. Among these structures, multivesicular bodies (MVBs) can accumulate many small vesicles in their lumen; release occurs upon MVB exocytosis. Ectosomes are larger vesicles characterized by their responses and are generated directly and released independently from specific microdomains pre-established in the thickness of the plasma membrane. Most lysosomes do not generate vesicles. However, unique components of a minor form, the endo-lysosome, constitute the third class of structures that release a few vesicles by exocytosis with molecules and structures inducing changes in the extracellular environment. The autophagosome, the fourth structure, releases several heterogeneous vesicles by exocytosis with malformed bio-molecules, assembled structures, and damaged organelles. Interestingly, the frequent interaction of autophagosomes with MVBs and their exosomes contributes to the regulation and intensity of their action. The specificity and function of released vesicles depend on their membranes’ and luminal cargoes’ composition and dynamics. An ongoing investigation of the various vesicles reveals new properties regarding their generation, release, and resulting extracellular processes. The growth of information about structures and their vesicles progressively extends the knowledge base regarding cell communication and contributes to their clinical applications.

Full textAbstract:
Rhinocyllus conicus Froelich was introduced and successfully established at 21 sites in northern Georgia for biological control of musk thistle, Carduus nutans L. A total of 9,310 adults were released from 1990 through 1992. Releases of reproductively mature adults in the spring were much more successful than summer releases of teneral adults. Progeny were observed in all spring-release sites, and population increases occurred at most sites one and two years after release. Consumption of infested capitula by cattle reduced R. conicus numbers at some sites. After two years, weevils had dispersed up to 0.6 km from the initial release point. Transfer of R. conicus to new sites in Georgia will begin in 1993.

Biochemical Journal 266, no. 3 (1990): 765–70. http://dx.doi.org/10.1042/bj2660765.
Full textAbstract:
Uric acid and uracil were released at constant rates (0.95 and 0.4 nmol/min per g respectively) by the perfused rat hindlimb. Noradrenaline, vasopressin or angiotensin II further increased the release of these substances 2-5-fold, coinciding with increases in both perfusion pressure (vasoconstriction) and O2 uptake. The hindlimb also released, but in lesser amounts, uridine, hypoxanthine, xanthine, inosine and guanosine, and all but hypoxanthine and guanosine were increased during intense vasoconstriction. Uric acid and uracil releases were increased by noradrenaline in a dose-dependent manner. However, the release of these substances did not fully correspond with the dose-dependent increase in O2 uptake and perfusion pressure, where changes in the latter occurred at lower doses of noradrenaline. Sciatic-nerve stimulation (skeletal-muscle contraction) did not increase the release of uracil, uric acid or uridine, but instead increased the release of inosine (7-fold) and hypoxanthine (2-fold). Since the UTP content as well as the UTP/ATP ratio are higher in smooth muscle than in skeletal muscle, it is proposed that release of uric acid and uracil arises from increased metabolism of the respective adenosine and uridine nucleotides during intense constriction of smooth muscle.

Full textAbstract:
BackgroundRecently released prisoners are at markedly higher risk of suicide than the general population. The aim of this study was to identify key risk factors for suicide by offenders released from prisons in England and Wales.MethodAll suicides committed by offenders within 12 months of their release from prison in England and Wales, between 2000 and 2002, were identified. One control matched on gender and date of release from prison was recruited for each case. Univariate and multivariate logistic regression modelling identified key independent risk factors for suicide.ResultsOf 256 920 released prisoners, 384 suicides occurred within a year of release. Factors significantly associated with post-release suicide were increasing age over 25 years, released from a local prison, a history of alcohol misuse or self-harm, a psychiatric diagnosis, and requiring Community Mental Health Services (CMHS) follow-up after release from prison. Non-white ethnicity and a history of previous imprisonment were protective factors.ConclusionsThere is a need to improve the continuity of care for people who are released from prison and for community health, offender and social care agencies to coordinate care for these vulnerable individuals.

Abstract After incubation with DNA human lymphocytes release neutral and acid DNase activities into the culture medium; the release depends on DNA concentration and time of cultivation. The electrophoretic mobility of the released neutral DNase activity is in accordance with DNase I and the electrophoretic mobility of the released acid DNase activity with DNase II. The released DNase activities do not originate from dead cells and are not influenced by blast cell formation. The anesthetic halothane can inhibit the released neutral and acid DNase activities. Inhalation anesthesia can possibly disturb the correlation between DNA and DNases in human blood.
