...observed that the normal circadian control of the morning and evening anticipation is also dependant on these potassium channels. The flies deficient in IRK1 channels didn’t show an evening anticipation peak. Another interesting disclosure during this study was the inability of PDF-Tri neurons to undergo programmed cell death in the absence of inwardly rectifying potassium channels. Hence, IRK1, though poorly expressed in the Drosophila central ne...

...od intake and dark light circadian rhythms. In rodents and higher primates its stimulatory role in HPG axis is reported. Growth hormone (GH) is released from anterior pituitary and directly or indirectly play very important role in regulation of HPG axis. In the present study the pathway of stimulatory role of NMS was investigated in the regulation of HPG axis. For this purpose, after NMS administration plasma testosterone (T) and growth hormone (GH) levels we...

...rrel species. Still, its circadian activity patterns and time budgets in different behaviors remain unclear. Using artificial population of the animal bred in a simulated natural environment, activity patterns and time budgets were investigated. The results showed that the species was clearly nocturnal but varied greatly in the number of daily activity bouts showing bimodal patterns in winter, trimodal patterns in spring and summer, even tetramodal patterns in...

...ave revealed the role of circadian rhythms in the estrous mode of mammals. In the present study, the expression patterns of six canonical clock genes (Clock, BMAL1, Cry1, Cry2, Per1 and Per2) were analyzed in year-round estrous rams (Small Tail Han sheep, STH) and seasonal estrous rams (Sunite sheep, SNT). The result showed that all six genes were expressed in brain, cerebellum, hypothalamus, pituitary, testis, epididymis, vas deferens and adrena...

...n: justify;">Feeding and circadian behavior of spiders occurring in two agricultural districts of Sindh, Pakistan were investigated over a four-year period from 2015-2018. Sample size was 2808 specimens which were arranged into 25 species, 15 genera and ten spider families. After analyzing the data from growing to harvesting of sugarcane, two spider guilds were identified on the basis of feeding and circadian behavior. Assem...
