Abstract:
Abstract The dies natalis papae has received little attention in the previous literature. This is not the actual birthday of the Roman chief pastor, but the anniversary of his consecration as bishop. Explicit evidence of this has been available since the second half of the 4th century (Damasus I), mainly in letters. However, the recording of the exact consecration dates since the 250s suggests that the day was also celebrated earlier. In any case, it is certain that the dies natalis papae was celebrated as a festival of joy and gratitude for the (albeit undeservedly conferred) Petrine office. Numerous bishops from all over Italy are invited to attend, and, if necessary, these gatherings can also be used for synods. While Leo I regularly exploits this opportunity to preach – five „Sermones“ have survived, after all – 150 years later Gregory the Great flatly rejects the celebration as „superfluous vanity“ and instead refers to the „birthday celebration“ of St. Peter himself. The Roman „Liber Diurnus“ has its own forms of epistolary „invitatoria in natale papae“ as well as „excusatoria quando episcopus infirmatur“, and the sacramentaries of this time contain models for the celebration, i. e. „Orationes in natale papae“ or „in natale episcoporum“.

Abstract:
Abstract The influence of container size and styrene lining on substrate temperature, and their relationship to ambient air temperature were evaluated. Maximum substrate temperatures adjacent to the west sidewall averaged 8C (14.4F) and 7C (12.6F) less in 2.7 liter (#1) and 10.3 liter (#3) containers with 2.6 mm (0.1 in) thick styrene, respectively, than in unlined containers during the summer. Maximum summer substrate temperatures in lined and unlined 10.3 liter (#3) containers were 4C (7.2F) and 5C (9F) lower, respectively, than in lined and unlined 2.7 liter (#1) containers. During diurnal periods of rapidly fluctuating winter temperatures, minimum substrate temperatures in 2.7 liter (#1) styrene-lined containers averaged 3C (5.4F) higher than in ones without styrene; styrene lining also reduced diurnal fluctuations in substrate temperatures in 2.7 liter (#1) and 10.3 liter (#3) containers by 11C (19.8F) and 7.5C (13.5), respectively, when compared to those in unlined containers. When ambient air temperature lacked wide fluctuations during winter diurnal cycles, extreme variations in substrate temperatures were not present. However, minimum substrate temperatures in styrene-lined 2.7 liter (#1) and 10.3 liter (#3) containers averaged over 2C (3.6F) and 3C (5.4F), respectively, higher than those in unlined containers.

Abstract:
Three year-old slash pine seedlings {Pinus elliottii) were transplanted from 3.8 liter (1 gal) plastic containers directly into the soil, in the soil within fabric containers, or into 57 liter (15 gal) plastic containers. After 2 yr in the nursery, trees grown by all three production methods were dug and retransplanted to a new site. Eight weeks prior to transplanting, half the soil-grown trees were root pruned. Water potential was measured on needle fascicles on a diurnal basis at least monthly after transplanting. Based on comparisons of diurnal water potential curves with nontransplanted control trees, trees which were transplanted from field soil or from fabric containers were established after 27 weeks. Trees planted from plastic containers required 35 weeks to become established.

Abstract:
Abstract Circulating leptin shows a pulsatile secretory pattern along with a nocturnal rise. We have previously shown that circulating leptin concentrations are high in males with untreated idiopathic hypogonadotropic hypogonadism (IHH). However, circadian leptin secretion in IHH before and after gonadotropin treatment is not known. Thus, we studied 14 adult males with IHH who had no history of previous hormonal therapy, and 12 age- and body mass index-matched healthy men. Plasma leptin concentrations were measured with 1-h intervals for 24 h before and 6 months after gonadotropin treatment. The 24-h mean leptin concentration showed a significant decrease, from 11.78 ± 1.908 μg/liter at baseline to 10.85 ± 1.939 μg/liter after 6 months of therapy (z = 3.107; P = 0.002). Before and after treatment, 24-h mean leptin concentrations were also significantly higher in the patient group when compared with controls (4.275 ± 0.711 μg/liter) (z = 5.938; P = 0.0001). Hourly leptin levels demonstrated a diurnal pattern in hypogonadal patients, a surge in the midday, and a peak just after midnight, and this pattern did not differ before and after treatment. We observed a similar diurnal pattern in the control subjects too. Leptin levels were negatively and significantly correlated with free testosterone and total testosterone levels both before (r = −0.656, P = 0.011; and r = −0.639, P = 0.014, respectively) and after (r = −0.537, P = 0.048; and r = −0.563, P = 0.036, respectively) gonadotropin administration. Our observations suggest that the diurnal rhythm of leptin is intact in males with IHH, and short-term gonadotropin treatment does not effect its diurnal rhythm. Moreover, testosterone produced under the influence of the gonadotropin treatment led to decreases in the leptin levels.

Abstract:
El propósito de la investigación fue sistematizar las experiencias vividas en ocho centros diurnos de la provincia de Heredia durante el periodo 2013-2017, a partir de intervenciones basadas en movimiento humano para la prevención del envejecimiento patológico. Las intervenciones realizadas se basaron en estrategias que buscaron promover el mantenimiento de diversas variables físicas predictoras de funcionalidad, las relaciones interpersonales positivas, la expresión de emociones y el uso positivo del tiempo libre. Para evaluar las experiencias de cada sesión se utilizó un instrumento de registro diario en línea que permitió obtener las distintas percepciones de los participantes de cada uno de los centros diurnos. De este modo, se registraron todas las experiencias durante el periodo comprendido entre el 2013 y el 2017 y se procedió a sistematizarlas por cada año de trabajo. Con base en la sistematización realizada, se concluye que una intervención basada en el movimiento humano, efectuada una vez por semana durante aproximadamente 50 min, permitió mantener a las personas usuarias de los centros diurnos motivadas, alegres, proactivas y dinámicas, por lo que se sugiere mantener este tipo de intervenciones en los centros diurnos.

Abstract:
The relation of the plasma potassium concentration to the daily cyclic variation in potassium excretion was examined in undisturbed, unanesthetized male Sprague-Dawley rats maintained on a liquid diet in a 12-h light-dark environment. Potassium excretion increased from a light-phase minimum of 16 mu eq/h to a peak of 256 mu eq/h 3 h after the beginning of the dark phase. Plasma potassium concentration in arterial blood, sampled in rats at 90-min intervals during these changes in potassium excretion, showed no significant change and was in the range 4.50-4.99 meq/liter. In adrenalectomized rats receiving aldosterone and dexamethasone at constant basal rates by implanted pumps, the daily cycle of potassium excretion was the same as in the intact rats, and plasma potassium was not significantly different when measured at the time of minimum and maximum rates of potassium excretion (4.79 +/- 0.42 vs 5.16 +/- 0.47 meq/liter, mean +/- SD). These results indicate that plasma potassium concentration is not the efferent factor controlling diurnal cyclic changes in potassium excretion in adrenal intact rats and may not be the only significant factor in adrenalectomized-steroid replaced rats.

Abstract:
Abstract Geosynthetic clay liners are widely used as hydraulic barrier due to their low hydraulic conductivity but bentonite in the liners loses its effectiveness due to significant thermal fluxes by both diurnal and seasonal heating and cooling cycles. Modified sodium carboxy methyl cellulose-based bentonite clay (HYPER clay) has shown better hydraulic performance in both situations. A possible reason for this improved performance of HYPER clay based geosynthetic clay liner is the improvement in the suction under changing thermal conditions. Thus, the relationship between soil suction and moisture content, also called the soil water retention curve, needs to be estimated. Therefore, we investigated the soil-water retention curve of the HYPER clay based geosynthetic clay liner and compared it with the untreated clay based geosynthetic clay liner. The article presents the suction test results on wetting path conducted on geosynthetic clay liner prototypes containing HYPER and untreated clay assessed by the contact filter paper method and the relative humidity sensor. The results showed that the geosynthetic clay liner containing HYPER clay has a high volumetric water content and thus, high water retention compared to untreated bentonite at a given suction value. In other words, the HYPER clay can be considered as a potential alternative to conventional bentonite due to its improved water retention capacity.

Abstract:
Abstract Context: Huntington’s disease (HD) is a fatal hereditary neurodegenerative disorder characterized by motor, cognitive, and behavioral disturbances. Hypothalamic-pituitary-adrenal (HPA) axis dysfunction could contribute to a number of HD signs and symptoms; however, no data are available on cortisol diurnal variations and secretory dynamics in HD patients. Objective: The aim of the study was to perform a detailed analysis of HPA axis function in HD patients in relation to clinical signs and symptoms. Design, Setting, and Participants: Twenty-four-hour cortisol secretion was studied in eight early-stage, medication-free HD patients and eight age-, sex-, and body mass index-matched controls in a clinical research laboratory. Cortisol levels were measured every 10 min. Main Outcome Measures: Multiparameter autodeconvolution and cosinor regression were applied to quantify basal, pulsatile, and total cortisol secretion rates as well as diurnal variations in cortisol levels. Results: Total cortisol secretion rate and the amplitude of the diurnal cortisol profile were both significantly higher in HD patients compared with controls (3490 ± 320 vs. 2500 ± 220 nmol/liter/24 h, P = 0.023; and 111 ± 14 vs. 64 ± 8 nmol/liter, P = 0.012, respectively). Cortisol concentrations in patients were particularly increased in the morning and early afternoon period. In HD patients, mean 24-h cortisol levels significantly correlated with total motor score, total functional capacity, as well as body mass index. Conclusions: HPA axis hyperactivity is an early feature of HD and is likely to result from a disturbed central glucocorticoid feedback due to hypothalamic pathology. HPA axis dysfunction may contribute to some signs and symptoms in HD patients.

Abstract:
Studies were performed in freely feeding, male (F1B) Syrian hamsters fed a high-fat diet to determine the extent and manner of adaptation of the liver to diurnal changes in eating patterns and an increase in serum lipids. Serum cholesterol and triglycerides strongly paralleled changes in food consumption and were 40-50% greater during the 12-h dark period than the 12-h light period of the diurnal cycle. Hepatic cholesterol changes closely approximated changes in serum cholesterol (r = 0.916) due principally to changes in hepatic cholesteryl esters that were on average about 10-fold greater with the high-fat diet than with a chow diet. With the high-fat diet, hepatic cholesteryl esters were, however, extremely variable and were 40% greater at the mid-dark than at the mid-light period. With high fat there was also a marked increase in the secretion of very low density lipoproteins (VLDL) from the liver that were cholesteryl ester rich and closely paralleled the diurnal changes in hepatic cholesteryl esters (r = 0.911). In contrast, although with a high-fat diet biliary cholesterol secretion was increased, the increase in cholesterol in bile exhibited no diurnal pattern and with the high-fat diet was far less in magnitude than the increase of cholesterol in VLDL. Biliary cholesterol secretion is dependent on bile acid secretion. However, with the high-fat diet, neither the bile acid pool size nor bile acid secretion was increased compared with chow-fed controls. Moreover, with high fat at mid-dark period, bile acid secretion was significantly less than controls at mid-dark period. Thus in these hamsters a high-fat diet produced a marked increase in serum cholesterol that was distinctly diurnal and was compensated for by a diurnal increase in hepatic cholesteryl ester stores and the secretion of cholesteryl esters in VLDL. In contrast, cholesterol secretion in bile did not correspond to the fluctuating changes of cholesterol in the liver and was far less in magnitude than would be necessary to reduce a greatly expanded pool of hepatic cholesterol.

Abstract:
Transtibial amputation (TTA) patients face ongoing morphological changes in their residual limb. The residuum volume changes due to weight gain or loss, diurnal edema, and muscle atrophy. Consequently, the TTA prosthetic-user is fitted with a new prosthetic socket approximately every four years. Despite new innovations in socket and liner materials and design, contemporary prosthetics are not yet equipped to confront these changes. The TTA residual limb is therefore subjected to high superficial and internal stresses which may cause injury. Appending the hazardous condition of natural volume change of the residuum is the initial geometrical state of the truncated bones. The primary surgical considerations in TTA are the tibial length, the bevelment of the distal end of the tibia and the location of the surgical scar. These risk factors may significantly affect the well being of the TTA residuum. Previous studies assumed that the criteria for a well-fitted socket were low interface stresses. However, while interface stress measurements may help prevent superficial skin damage, knowledge of the internal stress distribution can prevent the formation of deep tissue injury (DTI) [1]. While superficial pressure ulcers are visually detected, DTI is concealed under the skin and spreads to its surroundings in the soft tissues of the residuum. If this latent wound is ignored, the skin will rupture to reveal a massive injury to skin, fat and muscle tissues, clinically termed as a type IV pressure ulcer. Our purpose was to evaluate the effect of the following risk factors on the internal mechanical condition of the TTA residuum: shorter tibial lengths (thicker muscle flap tissue), milder tibial end bevelments, different mechanical properties of the muscle flap (simulating both variance between patients or flaccid versus contracted muscle) and superficial scarring in inferior and anterior locations on the skin.
