AIM To find the association between biochemical hypoglycemia on a 2-hour screening oral glucose tolerance test (OGTT) and insulin resistance. METHOD Subjects of this study were sampled from the China National Diabetes and Metabolic Disorders Study that was conducted during 2007 and 2008. Blood samples were drawn at 0, 30, and 120 minutes after the glucose load. Biochemical hypoglycemia was de...

objectives in this study the association of phenotypes and activity of butyrylcholinesterase (buche) with serum level of lipid-lipoprotein and apolipoproteins during various phases of menstrual-cycle was determined. methods the study population consisted of 22 healthy women aged 19–25 years with regular menstrual cycles, 26–30 days in length. the serum levels of lipids, apolipoproteins, and buc...

Portapres is a noninvasive, beat-to-beat finger blood pressure (BP) monitor that has been shown to accurately estimate 24-hour intra-arterial BP at normal and high BPs. However, no information is available on the ability of this device to accurately track ambulatory BP variability. In 20 ambulatory normotensive and hypertensive subjects, we measured 24-hour BP by Portapres and through a brachia...

Little is known about rest and sleep in dairy cows, but it has been shown in other species that the total amount of sleep, duration of sleep bouts and distribution of sleep over 24 hours differ depending on health status, age, pregnancy and lactation. Sleep recordings conducted on cows with surgically implanted electrodes have shown that they sleep four hours per 24-hour period. In this thesis,...

BACKGROUND Behaviour and time spent active and inactive are key factors in animal ecology, with important consequences for bioenergetics. For the first time, here, we equipped the gastropod Tectus (= Trochus) niloticus with accelerometers to describe activity rhythms at two sites in the Southwest Pacific with different temperature regimes: New Caledonia and Vanuatu. RESULTS Based on a 24-hour...

This study was carried out to investigate the effects of ivermectin on the hyaluronidase activities of blood serum and semen and on the sperm characteristics in sheep. In this investigation 18 sheep, at the age of 2 years and weighing between 5060kg were used. After the administration of ivermectin subcutanously at a dose of 0.2 mg/kg, semen and blood samples were taken at different times. The ...

This study surveyed 120 student nurses from two schools of nursing in Ibadan, Nigeria to assess the symptoms experienced during menstruation, attitude towards and management of menstruation. The student nurses overall mean age at menarche was 14 years, average duration of menstrual period was five days and mean of menstrual cycle was 28 days. Out of the 120 study participants, 93% were having m...

The murine female reproductive tract differentiates during postnatal development. This process of cytodifferentiation and morphogenesis is dependent upon specific mesenchymal-epithelial interactions as well as circulating steroid hormones (Cunha, G.R., 1976. Int. Rev. Cytol. 47, 137-194; Pavlova, A. et al., 1994. Development 120, 335-346). Members of the Wnt family of signaling molecules have b...

Introduction: In female rats sensitivity to antinociceptive treatment varies during estrous cycle stages. The role of GABA through GABAB receptor in nociception has been established. The aim of the present study is to investigate the effect of intercerebroventicular injection of GABAB receptor agonist (baclofen) and GABAB antagonist (CGP35348) on pain sensitivity during different stages of estr...

Studies o f 240 transthoracic fibrillation-defibrillation episodes in calves of 91-108 kg are reported. The waveform in 120 o f the episodes was a one-cycle, quasisinusoidal waveform having peak currents o f 64 and 3 2 A and half-cycle durations o f 4 and 6 ms. The episodes were interlaced with 120 others involving critically dam ped sinusoid wave­ forms having a 70.2-A peak current at 1.1 m s ...
