Full textAbstract:
Mandoor (Iron Oxide) is important in Rasashastra as a Dravya from Upadhatu Varg. It is widely used in Ayurveda therapeutics for the treatment of Pandu Roga, Kamala Roga, Rajakshaya and Raktakshaya. Mandoor is found buried inside the earth’s land and is said to be of mineral origin. Thus, it becomes important to get rid of physical and chemical impurities in Mandoor and make it potent for using it in therapeutics. To serve the necessity, Shodhana procedure is mentioned in classical texts of Ayurveda. The physical and chemical changes occurring during Shodhana make Mandoor suitable for the therapeutic use. In the classical texts of Ayurveda and Rasashastra numerous Shodhana procedures for Mandoor are found mentioned. So here an attempt was made to review various Shodhana procedures for Mandoor. In this context eighteen Vishesh Shodhana methods and a Samanya Shodhana found mentioned in different texts. A thorough review was carried out for the Shodhana procedures.

Full textAbstract:
In this study, it is aimed to determine the some interactions between various fishery types and seabirds, results of this interaction and sea bird species that have been interacting due to secondary attraction factors. A total of 80 fishermen, working in fish farms, small scale fishery (SSF) and lagoons located in Izmir, Aydın and Muğla were face-to-face interviewed between September 2016 and December 2018. The great cormorant (Phalacrocorax carbo), yellow-legged gull (Larus michahellis), great white egret (Ardea alba), some yelkouan shearwater (Puffinus yelkouan) and great white pelican (Pelecanus onocrotalus) are the bird species that have an interaction with coastal fishermen and sea-cage fish farms. 82% of employees in sea-cage fish farms mentioned that they have an interaction with sea birds in winter, besides %50 of SSF have an interaction with sea birds in summer. The difference between interaction rate according to seasons has been found as statistically significant (p<0.05). 33% of employees in fish farms expressed that they see sea birds during the day. This ratio is 21.7% and 15% for SSF and fishermen in lagoon, respectively. Furthermore, 8.3% of fishermen in lagoon, 11% of employees in fish farms and SSF mentioned that they have an interaction with seabirds especially in the morning time.

Full textAbstract:
There is growing evidence that exposure to nature increases human well-being, including in urban areas. However, relatively few studies have linked subjective satisfaction to objective features of the environment. In this study we explore the links among objective environmental features (tree cover, water, and bird diversity) and subjective judgements of satisfaction. We surveyed residents of Ottawa, Canada (n = 1035) about their satisfaction with their local neighbourhoods. We then compared the survey responses to measures of nature near their homes, including bird diversity (number of bird species), tree canopy cover, and distance to water. After controlling for effects of income and subjective happiness, residents’ neighbourhood satisfaction was positively related to the number of bird species nearby, even before participants were prompted to consider nature. Residents’ appreciation of their local neigbourhood relative to others also increased with tree canopy cover and nearness to water. Unsolicited comments from participants following the survey indicated that while residents consciously appreciate trees and water, the relationship between bird diversity and neighbourhood satisfaction appears to be unconscious; very few of the participants mentioned birds. Based on these results, we speculate that a diverse local bird community may provoke feelings of satisfaction through their presence, activity, and songs. Our results create a compelling argument for city planners and individual residents to maintain bird-friendly spaces in urban areas.

Full textAbstract:
Birdwatching is a very popular and increasing leisure activity, and the study and observation of birds is more popular in the morning due to the greater activity among birds at that time of day. The aim of our study was to find out whether there was a relationship between the circadian preference of observers and their favourite bird species and whether it was influenced by such factors as professional status, age and gender. In an e-mail survey we asked a total of 433 Polish ornithologists (professionals) or birdwatchers (non-professionals) for their morningness–eveningness preferences (four categories) and favourite (open choice) bird species and received 143 responses. The temporal (circadian) preferences of respondents declined from early morning (35.7%) to evening/nighttime (11.4%). Circadian preference categories differed significantly by age, with early morning respondents significantly older. These preference categories did not differ significantly in terms of response time to the survey invitation or in the percentage of their favourite birds that were categorised as daytime birds. A total of 204 species were identified as favourite birds of which 34 species were mentioned by five or more respondents, with only two, the common crane Grus grus and the Eurasian pygmy owl Glaucidium passerinum mentioned by more than 10% of respondents. The white stork Ciconia ciconia was more popular with professionals than non-professionals and the swift Apus apus less popular. A significant gender × circadian preference interaction was detected for the percentage of favourite birds categorised as daytime birds, with fewer daytime birds among early morning female recorders. The presented results are obviously of a correlative nature, but open the door for further, more advanced study and suggest there may be a need to investigate temporal biases when analysing citizen-based data.

Birds sexing utilize the Polymerase Chain Reaction (PCR) technique is increasingly being used by researchers and breeders. The PCR technique has high sensitivity, but its success is influenced by the specificity of the DNA template with the oligo primer used. This study aimed to evaluate 5 types of PCR primers P2/P8, 2550F/2718R, CHD1F/CHD1R, 1237L/1272H, and CHD1LF/CHD1LR to determine the sex of Phasianidae, Anatidae, Muscicapidae, and Psittacidae families. This research was conducted by tested primers mentioned above to amplify the target gene chromodomain helicase DNA binding 1 (CHD1) on DNA samples of each pair of males and females from four bird families, respectively. The results indicated that CHD1LF/CHD1LR PCR primer gave the best results and was recommended to determine the sex of four families tested. Some of other primers tested in this study failed to amplify targeted gene correctly, it is important to use appropriate primer to increase bird sexing accuracy.

Full textAbstract:
Abstract Urbanization in cultural landscapes generally tends to select for omnivorous, granivorous, and cavity/hole nesting bird species in green urban areas. Studies on bird diversity in the cities are important to better understanding to the ecology of urban and sub-urban landscapes. The aim of this study was research on bird diversity in urban parks in Olomouc city in order to brief comparison with bird diversity in hardwood floodplain forest habitats based on our older above-mentioned study. Bird diversity in urban parks was very similar to the bird diversity in some localities of floodplain forests from the Czech Republic. Comparison between urban parks and hardwood floodplain forests in the vicinity of the city revealed a high similarity of alpha-diversity and diversity indexes. These results indicated that large urban parks have nearly the same importance for bird diversity such as managed hardwood floodplain forests. Results highlighted an importance of urban green areas for biodiversity maintaining in European cultural landscapes.

Full textAbstract:
Background Automated sound recorders are a popular sampling tool in ecology. However, the microphones themselves received little attention so far, and specifications that determine the recordings’ sound quality are seldom mentioned. Here, we demonstrate the importance of microphone signal-to-noise ratio for sampling sonant animals. Methods We tested 12 different microphone models in the field and measured their signal-to-noise ratios and detection ranges. We also measured the vocalisation activity of birds and bats that they recorded, the bird species richness, the bat call types richness, as well as the performance of automated detection of bird and bat calls. We tested the relationship of each one of these measures with signal-to-noise ratio in statistical models. Results Microphone signal-to-noise ratio positively affects the sound detection space areas, which increased by a factor of 1.7 for audible sound, and 10 for ultrasound, from the lowest to the highest signal-to-noise ratio microphone. Consequently, the sampled vocalisation activity increased by a factor of 1.6 for birds, and 9.7 for bats. Correspondingly, the species pool of birds and bats could not be completely detected by the microphones with lower signal-to-noise ratio. The performance of automated detection of bird and bat calls, as measured by its precision and recall, increased significantly with microphone signal-to-noise ratio. Discussion Microphone signal-to-noise ratio is a crucial characteristic of a sound recording system, positively affecting the acoustic sampling performance of birds and bats. It should be maximised by choosing appropriate microphones, and be quantified independently, especially in the ultrasound range.

International Journal of Ayurvedic Medicine 14, no. 1 (2023): 225–28. http://dx.doi.org/10.47552/ijam.v14i1.3212.
Full textAbstract:
Panchapatchi Sasthiram or five bird diagnostic methodology is one among the diagnostic methods that relies on the concept of Panchabootha theory. Panchaboothas are represented by five birds (Patchi) in Panchapatchi Sasthiram (five bird diagnostic sign) which helps in cost effective diagnosis of various diseases. Objective: To evaluate the representative Patchi & Humours associated with Madhumegam (Diabetes Mellitus) patients as per Panchapatchi Sasthiram (five bird diagnostic sign) during consultation. Materials & Methods: A cross sectional study was conducted among 100 Madhumegam patients reported in the OPD of Ayothidoss Pandithar hospital. Panchapatchi calculation is the methodology of identifying the relevant affected action corresponding to each bird which may be further correlated to identify the affected Panchabhootham and affected humour in turn based on the waxing and waning of moon. Results: According to Siddha text; Pithavatham, Vathapitham and Vathakabam are the predominant humours in madhumegam. Among 100 patients assessed by means of Panchapatchi sasthiram (five bird diagnostic sign), 32 patients had pithavatham, 26 patients had vathakabam, 14 patients had vathapitham, 18 patients had kabavatham, 5 patients had kabapitham, 5 patients had kabam and it is observed that 72% participants possessed where of Naadinadai (Estimated through Panchaptchi sasthiram (five bird diagnostic sign)) as per the madhumegam literature. Conclusion: The Naadinadai (pulse play) mentioned in the literature agrees more than 70% with that of Panchapatchi based estimation. Hence it is hypothesized that Panchapatchi sasthiram based humoral assessment can be further evaluated as it is found helpful in the estimation of Naadinadai in diabetes mellitus. More over by means of this tool we can diagnose a condition with contactless evaluation.

Full textAbstract:
This article examines the relationship between genders and world history studies. Gender is commonly held to be a neglected topic in world historical scholarship. We could point to the ever-growing body of scholarship that has outlined how gender is implicated in the full range of human activities. The relations that bind men and women, men and men, and women and women together in social, political, economic, and cultural activities are so fundamental a part of human experience that they cannot be glossed over, passed by or passed on as the province of specialist historians. The discussion argues that there is no shortage of writing on gender in world history. What is still lacking, however, is widespread awareness of the extent to which gender shapes world historical research, writing, and teaching, particularly works in which women are not mentioned.

This chapter focuses on immunobullous diseases. The immunobullous disorders are a group of diseases in which pathogenic autoantibodies bind to target antigens either in desmosomes (intra-epidermal intracellular adhesion junctions) or in part of the basement membrane zone, resulting in loss of adhesion, and blister formation. This chapter will focus on pemphigus vulgaris, pemphigus foliaceus, bullous pemphigoid, linear IgA disease, chronic bullous disease of childhood, and dermatitis herpetiformis; it will also mention mucous membrane pemphigoid, pemphigoid gestationis, and epidermolysis bullosa acquisita.

Abstract It’s amusing, in a dismaying sort of way, to watch the occasional pop critic of the ‘90s recapitulate the contempt for received wisdom that made much ‘60s criticism seem arrogantly self-satisfied. You know, the solemn young writers who have no intention of aging themselves, and who treat Dylan, Jagger, McCartney, and Fat Elvis (the one who lost the stamp election) as grizzled hacks who should have retired gracefully or died with the glow of flaming youth. After glimpsing Jagger, never a favorite of mine, on Saturday Night Live, I admit to sharing in the ridicule: why did he appear ludicrous, while Jimmy Witherspoon, his senior by two decades, was riveting at Fat Tuesday’s last week, singing blues that were venerable when Jagger was born? Wasn’t Jagger once touted as a kind of white bluesman? Did he forget everything he ever knew, or has he come to accept his own limitations? Witherspoon mentioned Jagger as playing a role in his receiving a Lifetime Achievement award from the Rhythm-and-Blues Foundation this week, an event certified with a ceremonial performance of his signature tune, “Ain’t Nobody’s Business.”

Abstract For the last decade, whenever I mentioned to anyone that I was working on a life of Bing Crosby, the usual response was, “Why?” I can’t say I was surprised. For 30 years, between 1927 and 1956, Crosby was a looming presence in America’s cultural landscape. At the peak of his career, in the 1930s and 1940s, he was thought by many to be the most famous American alive. For much of that period, he was undoubtedly the most beloved. The cycle of “Road” pictures with Bob Hope established Crosby as an accomplished comic actor. Yet by the 1960s, the ocean began to roll over Der Bingle, and though he continued to sell millions of records—chiefly holiday songs—he had morphed into a grand old man while retaining little of the bite of his contemporary, Louis Armstrong, or his offspring, Frank Sinatra. When he made his unexpected return to the stage in 1976, at New York’s Uris Theater (his first live appearance before a paying audience in more than 40 years), I attended a rehearsal as well as the show, and spoke with him briefly. My review (included in Riding on a Blue Note) was appreciative but skeptical. I found him at once irresistible and detached, a fascinating vestige from another age.

Abstract Oliver Lake was nearly 30 when his first recordings made their way— via his own label, Passin’ Thru—from St. Louis to New York. That was 20 years ago, and his subsequent career offers a kind of Baedeker of the era’s jazz itinerary. First we encountered him, along with many promising musicians of the early ‘70s, in a collective (St. Louis’s Black Artists Group), performing with a malleable ensemble that favored “little instruments” and modal subjects, or standing alone, an unaccompanied altoist with a distinctively stark, urgent style. He made the obligatory trip to Paris before settling in Brooklyn, part of an unusually mature generation of newcomers who were bred in all the new musics of the ‘60s, rock and soul as well as jazz, and could hear beyond them to previously established forms and functions. Although he mentioned Paul Desmond and Jackie McLean as early inspirations, Lake had a sound as individual as his hair, a tonsure circled by dreads. His timbre was cured in acid, but his intonation remained centered and sure. By the end of the ‘70s, he had recorded two sets of duets (notably Buster Bee, with Julius Hemphill), and embarked on a long alliance with drummer Pheeroan ak Laff.

Full textAbstract:
Animal domestication is a subject rarely discussed within the Mesoameri- can faunal studies agenda. In the case of birds, it is often mentioned that the guajolote or wild turkey (Meleagris gallopavo) was the only domesticated bird. To explore this assertion, this essay focuses on the study of birds recorded in historical chronicles that refer to the Mexica Postclassic, and compares it to the currently known, but limited, archaeozoological record. A total of 36 birds were found to be part of the domestic sphere. This suggests that they could have been held captive for the purpose of being exploited. Through the use of an “Exploitation Index by Taxon” it was de- termined that terrestrial bird groups, such as Phasianinae, pigeons, parrots, and woodpeckers, were the most intensely used species. Meanwhile, it was established that decorative, dietary, and song aspects were the main uses assigned to the widest diversity of birds. It has also become evident that there is great uncertainty in bird identification in historical chronicles, quite possibly due to the differences between traditional and biological taxonomy. The resulting data suggest this is a promising research subject.

Full textAbstract:
Abstract Naturally occurring species in grasslands do not exist in an ecological vacuum; they confront scores of other species on a daily basis. In some cases, the interaction is a positive one for both participants (mutualism), as occurs between a flower and its pollinating fly, bee, or butterfly. Other, equally routine interactions have negative consequences for one or both participants, including competition among coexisting grasses for limited water, light, or nutrients; grasshoppers eating seedling plants (herbivory); or birds eating the grasshopper just mentioned (predation). These direct interactions determine population sizes of coexisting species and often modify spatial distributions as well. Indirect interactions are at least equally common and possibly more important. For example, a bird feeding on a seedling-feeding grasshopper exerts a positive effect on the host plant population without interacting with it directly, since the bird makes life for plant seedlings a little more secure. If that particular seedling grows and creates important habitat for the bird, both species benefit, the bird twice because it gets to eat grasshoppers as well as build a nest. Such is the nature of interactions in natural systems-straightforward and intuitive in concept, but often complex and convoluted in practice.

Full textAbstract:
This is an animal design project (design thinking to meet the needs of animals) which aims to bring birds into contact with humans and - through this solution - to bring the sound and movement produced by them into our lives (whether in the countryside, whether in the urban landscape), which can be translated into joy and peace achieved by the harmony of natural wildlife in our domestic environment.Starting question Knowing that birds are elusive and fearful animals, but also can bring joy and movement to our daily lives, how can we attract them to our coexistence? Supplementary feeding can be a good solution, and there are already some versions available on the international market, especially in countries where winter is more extreme. In southern Europe, feeding birds is still not a very common practice. Depending on the type of food the birds eat in their natural habitat and, depending on the endogenous birds, there are variations in the diet, and only a test of placing food available to the birds will determine the type of food to be placed in the supplementary feeder.The "AlimentáRIO" (feeder) is a ceramic supplementary feeding stand/holder that can contain various types of food, in order to test if birds can be attracted close to your home.There are several types of bird food: nectar, seeds, worms, fruit, tallow/lard... And, for each of these types of food, there is a specific type of feeder. The "AlimentáRIO" is a versatile feeder intended to cover all types. Nectar is more suitable for birds that can pollinate during late winter and early spring, when insects are less active. For these reasons, nectar should only be placed in feeders as a food supplement in the winter and autumn.In Portugal, there are some birds that drink nectar, according to Luís Pascoal da Silva , a researcher at CIBIO-inBIO. The scientist states that there are several pollinating birds in Portugal, but the study of the contribution of these birds to pollination is scarce. Seeds - besides the traditional canary seed - can contain sunflower seeds or nuts, such as walnuts and peanuts, depending on the endogenous birds. Fruit is also sought after by some species of birds, namely apples and pears, in addition to other exotic fruits. However, in general, birds can be drawn to any type of fruit. Fat balls are usually tallow/lard balls with seeds and fruits to reinforce supplementary feeding during cold seasons. The "AlimentáRIO" is a suspended wild bird feeder that can be hung in more or less sheltered places, made with materials resistant to the elements, without the need for maintenance. However, its cleaning must be done according to the recommendations referred to in the full article. As already mentioned, the construction materials are low maintenance, and the food container and the deflecting bell jar are made with stoneware - the type of ceramics more resistant to both bumps and thermal variations. The junction of the two parts is made with a nickel-plated threaded rod, covered with an aluminium tube, and all components are joined by manual screw threads, which allows to assemble and disassemble it without the use of any tools, thus facilitating an in-depth cleaning at the end of the supplementary feeding season.The "AlimentáRIO" has a lower part with four concavities for placing food, which allows the possible placement of different types of food at the same time, thus drawing different species. As it is a feeder consisting of a protective and deflecting bell jar, the birds are protected from possible direct attacks from predators and from falling leaves in the autumn. The fact that it is a supplementary feeder that can be hung with a rope makes it difficult for rats and squirrels to get close to the food, given that, if by chance these animals manage to descend on the rope, they must also overcome the challenge of getting through the bell jar (which is a spherical cap) to get to the place where the food is. The results of the placement tests of this supplementary feeder have been reassuring, which show that the feeders foster the approximation of wild birds in relatively short periods of time - between 3 weeks and one month.

Animals are products of nature and have evolved over millions of years to perform better in their activities. Engineering research and development can benefit greatly by looking into nature and finding engineering solutions by learning from animals’ evolution and biological systems. Another relevant factor in the present context is highlighted by the statement of the Nobel laureate Richard Smalley: “Energy is the single most important problem facing humanity today.” This paper focuses on how the research and education in the area of Dynamic Systems can be geared towards these two considerations. In particular, recent advances in self-powered dynamic systems and bio-inspired dynamic systems are highlighted. Self-powered dynamic systems benefit by capturing wasted energy in a dynamic system and converting it into useful energy in the mode of a regenerative system, possibly in conjunction with renewable energies. Examples of solar-powered vehicles, regenerative vibration control, and energy harvesting are presented in the paper. Particularly, development of solar-powered quadrotor, octocopter, and tricopter airships are presented, a self-powered vibration control of a mass-spring system using electromagnetic actuators/generators, and piezoelectric flutter energy harvesting using bi-stable material are discussed. As examples of bioinspired dynamic systems, flapping wing flying robots, vertical axis wind turbines inspired by fish schooling, propulsion inspired by jellyfish, and Psi Intelligent Control are given. In particular, various design and developments of bird-inspired and insect-inspired flapping wings with the piezoelectric and electromagnetic actuation mechanisms, a scaled vertical axis wind turbine farm consist of 4 turbines and the corresponding wind tunnel testing, jellyfish-inspired pulsing jet and experimenting the increase in efficiency of energy consumption, and a multi-agent/robotic based predictive control scheme inspired by Psi precognition (event or state not yet experienced). Examples of student projects and research carried out at Brunel University and the experimental rigs built (in all the mentioned areas) are discussed, as an integrated research and educational activity. For the analysis and understanding of the behavior of self-powered and bio-inspired systems, Optimal Uncertainty Quantification (OUQ) is used. OUQ establishes a unified analysis framework in obtaining optimized solutions of the dynamic systems responses, which takes into account uncertainties and incomplete information in the simulation of these systems.

Udofia, Emmanuel. "Empirical Design of Optimum Frequency of Well Testing for Deepwater Operation." In Offshore Technology Conference. OTC, 2021. http://dx.doi.org/10.4043/31180-ms.
Full textAbstract:
Abstract Well testing could be described as a process required to calculate the volumes of (oil, water and gas) production from a well in a bid to identify the current state of the well. Amongst other things, well testing aims to provide information for effective Well, Reservoir and Facility Management. Normally, as a means of well performance health-check, reconciliation factor (RF) is generated by comparing the fiscal production volume against the theoretical well test volume. Experiences from the Coronavirus pandemic has brought about the new normal into well test execution. In deepwater environment, the process of well testing is more challenging and this paper aims to address these challenges and propose optimum well test frequency for deepwater operations. It is usually required that routine well test be conducted once every month on all flowing strings, this is for statutory compliance and well health-check purposes. However, in deepwater environment, it is difficult to comply with this periodic well test requirement mainly due to production flow line slugging, plant process upset and/or tripping resulting in production deferment and operational risk exposure. Furthermore, to carry out well test in deepwater operation, production cutback is required for flow assurance purpose and this usually results in huge production deferment. In this field of interest, this challenge has been managed by deploying a data-driven application to monitor production on individual flowing strings in real-time thereby optimizing the frequency of well test on every flowing well. Varying rate well test data are captured and used to calibrate this tool or application for subsequent real-time production monitoring. This initiative ensures that all the challenges earlier mentioned are managed while actually optimizing the frequency of testing the wells using intelligent application which serves as a ‘virtual meter’ for testing all producing wells in real time. As mentioned, well testing in most deepwater assets remain a big challenge but this project based field experience has ensured effective well testing operation resulting in reduction of production deferment and safety exposure during plant tripping whilst optimizing frequency of testing the wells. Following this achievement of the optimized well test to quarterly frequency in this field in Nigerian deepwater, recommendation from this paper will assist other deepwater field operators in managing routine well testing operation optimally.

As economic and human development problems worsen, the majority of countries are relying on technological development to emerge from the crisis, whether it is the infectious disease crisis or the natural resource depletion crisis. Modern technology contributes to reducing the effects of both environmental pollution and the spread of HIV infection, Given the results of quarantine on the environment, it can be said that the importance of the latter is reflected in:Creating new vaccines and vaccines to eradicate the virus, Adopting environmentally friendly production mechanisms ,Adopt policies to reduce the depletion of natural resources, The trend towards the use of renewable energies to maintain the sustainability of the environment, Emphasizing the need to adopt a green economy and sustainable development.so the methods of disposing of medical waste differ from one country to another, In some places, waste is collected and sterilized, then sent to sanitary landfills or incinerated It is no secret to everyone that the amount of masks, gloves and other personal protection tools that were used during the pandemic period has exceeded twice their use before the pandemic. This in itself is a burden on an environment that already suffers from the problems of disposing of solid and liquid waste in a correct manner and in conformity with global health, After the transformation of medical waste into hazardous waste and the readiness of the competent teams to deal with the crisis, they were suffering from a weakness in the methods of disposing of this waste and with accurate preventive measures during the outbreak of the Covid-19 pandemic, We found it necessary to mention in this research the impact of the pollution resulting from those wastes that affected the countries of the whole world and how to find ways to increase the awareness of the individual in our Iraqi society, similar to advanced societies in dealing with the remnants of covid-19, Which has proven in some scientific sites with graphic documentation about the use of these wastes in their countries by some birds in building their nests and caused death to some of them after swallowing them and others by clashing in their claws and the difficulty of getting rid of them for weeks due to the incorrect disposal of solid waste in particular by the municipalities similar to the lack of support and experience.

Full textAbstract:
Activation of platelets by agonists acting via cell surface-located receptors apparently involves as an early event in transmembrane signalling an interaction of the agonist-occupied receptor with a guanine nucleotide-binding regulatory protein (G-protein). The activated G-protein, then, transduces the information to the effector molecule, being responsible for the changes in intracellular second messengers. At least two changes in intracellular signal molecules are often found to be associated with platelet activation by agonists, i.e., increases in inositol trisphosphate and diacylglycerol levels caused by activation of a polyphosphoinositide-specific phospholipase C and decrease in cyclic AMP concentration caused by inhibition of adenylate cyclase.Both actions of platelet-activating agents apparently involve G-proteins as transducing elements. Generally, the function of a G-protein in signal transduction can be measured either by its ability to regulate the activity of the effector molecule (phospholipase C or adenylate cyclase) or the binding affinity of an agonist to its specific receptor or by the abitlity of the G-protein to bind and hydrolyze GTP or one of its analogs in response to agonist-activated receptors. Some platelet-activating agonists (e.g. thrombin) can cause both adenylate cyclase inhibition and phospholipase C activation, whereas others induce either inhibition of adenylate cyclase (e.g. α2-adrenoceptor agonists) or activation of phospholipase C (e.g. stable endoperoxide analogs) . It is not yet known whether the simultaneous activation of two signal transduction systems is due to activation of two separate G-proteins by one receptor, to two distinct receptors activating each a distinct G-protein or to activation of two effector molecules by one G-protein.For some of the G-proteins, rather specific compounds are available causing inactivation of their function. In comparison to Gs, the stimulatory G-protein of the adenylate cyclase system, the adenylate cyclase inhibitory Gi-protein is rather specifically inactivated by ADP-ribosylation of its a-subunit by pertussis toxin, “unfortunately” not acting in intact platelets, and by SH-group reactive agents such as N-ethylmaleimide and diamide, apparently also affecting the Giα-subunit. Both of these treatments completely block α2-adrenoceptor-induced GTPase stimulation and adenylate cyclase inhibition and also thrombin-induced inhibition of adenylate cyclase. In order to know whether the G-protein coupling receptors to phospholipase C is similar to or different from the Gi-protein, high affinity GTPase stimulation by agents known to activate phospholipase C was evaluated in platelet membranes. The data obtained indicated that GTPase stimulation by agents causing both adenylate cyclase inhibition and phospholipase C activation is reduced, but only partially, by the above mentioned Gi-inactivating agents, while stimulation of GTPase by agents stimulating only phospholipase C is not affected by these treatments. These data suggested that the G-protein regulating phospholipase C activity in platelet membranes is different from the Gi-protein and may also not be a substrate for pertussis toxin. Measuring thrombin stimulation of inositol phosphate and diacylglycerol formation in saponin-permeabilized platelets, apparently contradictory data were reported after pertussis toxin treatment, being without effect or causing even an increase in thrombin stimulation of inositol phosphate formation (Lapetina: BBA 884, 219, 1986) or being inhibitory to thrombin stimulation of diacylglycerol formation (Brass et al.: JBC 261, 16838, 1986). These data indicate that the nature of the phospholipase C-related G-protein(s) is not yet defined and that their elucidation requires more specific tools as well as purification and reconstitution experiments. Preliminary data suggest that some antibiotics may serve as useful tools to characterize the phospho-lipase-related G-proteins. The possible role of G-protein phosphorylation by intracellular signal molecule-activated protein kinases in attenuation of signal transduction in platelets will be discussed.

Full textAbstract:
Breeding colonies of wading birds (orders Ciconiiformes, Pelecaniformes) and seabirds (orders Suliformes, Pelecaniformes) serve as important indicators of aquatic ecosystem health, as they respond to changes in food abundance and quality, contaminants, invasive species, and disturbance. The Comprehensive Everglades Restoration Plan, Restoration Coordination & Verification program (CERP-RECOVER) has identified wading-bird colonies as an important ecosystem restoration indicator. The National Park Service South Florida/Caribbean Inventory & Monitoring Network (SFCN) ranked colonial nesting birds eighth out of 44 vital signs of park natural resource conditions for ecological significance and feasibility. However, while large-scale monitoring efforts are occurring in the rest of the Greater Everglades Ecosystem, only minimal historic data collection and no extensive ongoing monitoring of wading bird and seabird nesting have occurred in Biscayne National Park. Consequently, due to their high importance as biological indicators and because they are a gap occurring in regional monitoring efforts, the network has initiated a monitoring program of colonial nesting birds in Biscayne National Park. This protocol provides the rationale, approach, and detailed Standard Operating Procedures for annual colonial bird monitoring within and close to Biscayne National Park and conforms to the Oakley et al. (2003) guidelines for National Park Service long-term monitoring protocols. The specific objectives of this monitoring program are to determine status and long-term trends in: Numbers and locations of active colonies of colonial nesting birds with a special focus on Double-crested Cormorants, Great Egrets, Great White Herons, Great Blue Herons, White Ibises, and Roseate Spoonbills. Annual peak active nest counts of colonial nesting birds in Biscayne National Park with a special focus on the species mentioned above. An annual nesting index (i.e., sum of monthly nest counts) with a special focus on the species mentioned above. Timing of peak nest counts for the focal species.

Full textAbstract:
The avian influenza virus, subtype H9N2 subtype, defined as having a low pathogenicity, causes extensive economical losses in commercial flocks, probably due to management and synergism with other pathogens. AIV H9N2 was first identified in Israel in the year 2000, and since then it became endemic and widespread in Israel. Control by vaccination of commercial flocks with an inactivated vaccine has been introduced since 2007. In face of the continuous H9N2 outbreaks, and the application of the vaccination policy, we aimed in the present study to provide a method of differentiating naturally infected from vaccinated animals (DIVA). The aim of the assay would be detect only antibodies created by a de-novo infection, since the inactivated vaccine virus is not reproducing, and might provide a simple tool for mass detection of novel infections of commercial flocks. To fulfill the overall aim, the project was designed to include four operational objectives: 1. Evaluation of the genetic evolution of AIV in Israel; 2. Assessment of the diagnostic value of an NS1 ELISA; 3. NS1 ELISA as evaluation criteria for measuring the efficacy of vaccination against H9N2 AIV; 4. Development of an AIV H9 subtype specific ELISA systems. Major conclusion and implications drawn from the project were: 1. A continuous genetic change occurred in the collection of H9N2 isolates, and new introductions were identified. It was shown thatthe differences between the HA proteins of viruses used for vaccine productionand local fieldisolatesincreasedin parallelwith the durationand intensity ofvaccine use, therefore, developing a differential assay for the vaccine and the wild type viruses was the project main aim. 2. To assess the diagnostic value of an NS1 ELISA we first performed experimental infection trials using representative viruses of all introductions, and used the sera and recombinant NS1 antigens of the same viruses in homologous and heterologous NS1 ELISA combination. The NS1 ELISA was evidently reactive in all combinations, and did not discriminate significantly between different groups. 3. However, several major drawbacks of the NS1 ELISA were recognized: a) The evaluation of the vaccination effect in challenged birds, showed that the level of the NS1 antibodies dropped due to the vaccination-dependent virus level drop; b) the applicability of the NS1-ELISA was verified on sera of commercial flocks and found to be unusable due to physico-chemical composition of the sera and the recombinant antigen, c) commercial sera showed non-reactivity that might be caused by many factors, including vaccination, uncertainty regarding the infection time, and possibly low antigen avidity, d) NS1 elevated antibody levels for less than 2 months in SPF chicks. Due to the above mentioned reasons we do not recommend the application of the DIVA NS1 ELISA assay for monitoring and differentiation AIV H9N2 naturally-infected from vaccinated commercial birds.

Full textAbstract:
The principal accomplishment of the research supported by BARD was progress toward a comprehensive view of cell-surface electrical effects (both in cell walls [CWs] and at plasma membrane [PM] surfaces) upon ion uptake, intoxication, and amelioration. The research confirmed that electrostatic models (e.g., Gouy-Chapman-Stern [G-C-S]), with parameter values contributed by us, successfully predict ion behavior at cell surfaces. Specific research objectives 1. To characterize the sorption of selected heavy metals (Cu, Zn, Pb, Cd) to the root PM in the presence of other cations and organic ligands (citric and humic acids). 2. To compute the parameters of a G-C-S model for heavy-metal sorption to the root PM. 3. To characterize the accumulation of selected heavy metals in various plant parts. 4. To determine whether model-computed ion binding or ion activities at root PM surfaces predict heavy-metal accumulation in whole roots, root tips, or plant shoots. 5. To determine whether measured ion binding by protoplast-free roots (i.e., root CWs) predicts heavy-metal accumulation in whole roots, root tips, or plant shoots. 6. To correlate growth inhibition, and other toxic responses, with the measured and computed factors mentioned above. 7. To determine whether genotypic differences in heavy-metal accumulation and toxic responses correlate with genotypic differences in parameters of the G-C-S model. Of the original objectives, all except for objective 7 were met. Work performed to meet the other objectives, and necessitated on the basis of experimental findings, took the time that would have been required to meet objective 7. In addition, work with Pb was unsuccessful due to experimental complications and work on Cd is still in progress. On the other hand, the uptake and toxicity of the anion, selenate was characterized with respect to electrostatic effects and the influences of metal cations. In addition, the project included more theoretical work, supported by experimentation, than was originally planned. This included transmembrane ion fluxes considered in terms of PM-surface electrical potentials and the influence of CWs upon ion concentrations at PM surfaces. A important feature of the biogeochemistry of trace elements in the rhizosphere is the interaction between plant-root surfaces and the ions present in the soil solution. The ions, especially the cations, of the soil solution may be accumulated in the aqueous phases of cell surfaces external to the PMs, sometimes referred to as the "water free space" and the "Donnan free space". In addition, ions may bind to the CW components or to the PM surface with variable binding strength. Accumulation at the cell surface often leads to accumulation in other plant parts with implications for the safety and quality of foods. A G-C-S model for PMs and a Donnan-plus-binding model for CWs were used successfully to compute electrical potentials, ion binding, and ion concentration at root-cell surfaces. With these electrical potentials, corresponding values for ion activities may be computed that are at least proportional to actual values also. The computed cell-surface ion activities predict and explain ion uptake, intoxication, and amelioration of intoxication much more accurately than ion activities in the bulk-phase rooting medium.
