Beneficial effects of' trace amounts of dietary Se were first observed in vitamin E-deficient rats so that a strong metabolic interaction between these two micronutrients was apparent since the initial discovery of the nutritional value of Se (Schwarz & Foltz, 1957). Later work showed that Se and vitamin E tended to spare one another's requirement for the prevention of certain nutritional defic...

Extensive use of torpor is a common winter survival strategy among bats; however, data comparing various torpor behaviors among species are scarce. Winter torpor behaviors are likely to vary among species with different physiologies and species inhabiting different regional climates. Understanding these differences may be important in identifying differing susceptibilities of species to white-n...

BACKGROUND Early life stress (ELS) can compromise development, with higher amounts of adversity linked to behavioral problems. To understand this linkage, a growing body of research has examined two brain regions involved with socioemotional functioning-amygdala and hippocampus. Yet empirical studies have reported increases, decreases, and no differences within human and nonhuman animal samples...

Standard WHO insecticide bioassay tests were carried out in Gorgora, northern Ethiopia to evaluate the susceptibility status of Anopheles pharoensis Theobald for the insecticides DDT, malathion, permethrin and deltamethrin. The mortality and when appropriate knockdown effect of the insecticides were observed. The results indicated that this species was resistant to DDT. A high mortality was obt...

Theselectionof chemotherapy inaquatic animalmedicine is not as straightforward as one might believe. A multitude of factorscan impacteffectiveness insitu. Someof these factors include the pathogen(s) present and their antimicrobial susceptibility, site(s) of infection, timing of treatment, host health/disease status, dose and regimen, water salinity, and water temperature.

The cause of the current increase in obesity in westernized nations is poorly understood but is frequently attributed to a 'thrifty genotype,' an evolutionary predisposition to store calories in times of plenty to protect against future scarcity. In modern, industrialized environments that provide a ready, uninterrupted supply of energy-rich foods at low cost, this genetic predisposition is hyp...

Forty patients with migraine who were attending a specialist clinic were interviewed with the Schedule for Affective Disorders and Schizophrenia--Lifetime version. Sixteen (40%) had a history of major depression which was of endogenous type in 15, according to Research Diagnostic Criteria. The tyramine test, a previously established trait marker for endogenous depression, showed that the migrai...

The epsilon4 haplotype of APOE is the only undisputed genetic risk factor for late-onset Alzheimer's disease (LOAD). It has been proposed that at least two other polymorphisms in the promoter of the APOE gene (-219G>T and -491A>T) might also contribute to disease susceptibility, and modulate the impact of structural changes in the ApoE protein, by altering its expression. In order to assess the...

BACKGROUND Previous studies on gene-lifestyle interaction and obesity have focused mostly on the FTO gene and physical activity, whereas little attention has been paid to sedentary behavior as indicated by television (TV) watching. METHODS AND RESULTS We analyzed interactions between TV watching, leisure time physical activity, and genetic predisposition in relation to body mass index (BMI) i...

Psychosis occurring in epileptics has always been an area of research interest, particularly, because of possible link of mental illness, organic lesions, convulsive process and behavioural abnormlity, all occuring together in the same subject. Vast amount of investigation on this subject has been done with a view to understand something more fundamental in 'Brain-Behaviour Connection'. Occuran...
