The trematode Microphallus sp. alters the behavior of its snail intermediate host, Potamopyrgus antipodarum, in ways that seem to increase transmission to its final host, e.g., waterfowl, and decrease the probability of being eaten by other predators, e.g., fish. The parasite seems to cause the snail to move from the top to the bottom of rocks at about 0900 hr. Waterfowl feed predominantly befo...

The study was conducted to investigate diurnal changes in pinealocyte ultrastructure, pineal serotonin content and plasma melatonin concentration in the domestic pig. The immature pigs (n=24) were kept under a cycle of 12 h light : 12 h dark, with a photophase between 0800 and 2000. During the photophase the animals were exposed to direct sunlight. After four weeks the gilts were slaughtered at...

OBJECTIVE A common approach to screening for gestational diabetes mellitus (GDM) is the universal testing of all pregnant women with a 1-h, 50-g glucose challenge test (GCT), followed by a diagnostic oral glucose tolerance test (OGTT) in those in whom the GCT is positive (≥7.8 mmol/L). More important, the GCT is performed at any time of day, but there has been limited study of the effect of tim...

Investigations on the influence of oviposition time functional properties egg shell domestic fowl were conducted. The eggs used for study laid by commercial Lohmann pullets - a temperate hybrid. laying birds managed singly in battery cages, fed layer's diet about 17% crude protein and supplied water. results showed mean thickness was 0.31, 0.33,0.34 0.35mm between 0600 0900, 0900 1200, 1200 150...

Cherry is a hand-harvested fruit due to various difficulties and constraints. This condition results in the use of labor at high rate. Turkey's annual cherry production level 724 thousand tons. Various tools or machines that have been developed for harvest potential contribute greatly this area. The share required harvesting total requirement around 70%. In research, it was aimed collect necess...

INTRODUCTION We examined the responsiveness of both cortisol and dehydroepiandrosterone sulfate (DHEAS) to the stress of survival training in military men and evaluated relationships to performance, peritraumatic dissociation, and the subsequent impact of stressful events. METHODS Baseline salivary cortisol samples were self-collected by 19 men at 0900 and 1930 in a free-living (FL) environme...

Overnight basal insulin requirements to maintain euglycemia were determined in five insulin-dependent diabetic subjects using a closed-loop insulin infusion system. A significant increase in hourly insulin requirements occurred between 0600 h and 0900 h as compared with 0100 h-0600 h. Although the increased insulin requirement was coincident with only the physiologic diurnal increase in plasma ...

OBJECTIVE To assess whether intermittent transdermal treatment with glyceryl trinitrate causes clinically significant rebound in patients maintained on beta blockers for stable angina pectoris. DESIGN Serial treadmill exercise testing in a double blind, randomised, placebo controlled cross over trial. Baseline exercise testing was performed at 0900 and 1100 at visit 1. Transdermal glyceryl tr...
