The effect on thermotolerance of the incompletely dominant frizzle (F) gene, which causes feather curling and feather mass reduction, was investigated in 281 laying hens that were homozygous for the frizzle mutation (FF), heterozygous (FN), or normally feathered (NN). One-half of the birds were kept under standard conditions (22°C) and half were exposed to high ambient temperatures (32°C) betwe...

Abstract There is dearth information on the role of fisetin as an antistress agent in ameliorating heat stress broiler chickens. Here, we experimentally compared probiotic, antioxidant and agent, with fisetin, little or no report its effect. Sixty-day-old chickens (Arbo Acre breed) were allotted into 4 groups 15 birds each follows; control, + probiotic groups, respectively. All administrations ...

Temperature affects all biological functions and will therefore modulate ecologically significant interactions between animals and their environment. Here, we examined the effect of ambient temperature (Ta) on the thermal biology and energy budget in striped hamsters acclimated to cold (5°C), warm (21°C) and hot temperatures (31°C). Thermoneutral zone (TNZ) was 22.5-32.5°C, 25-32.5°C and 30-32....

Vasomotor symptoms or hot flushes are periods of intense heat, sweating and peripheral vasodilation. Hot flushes and night sweats are the most commonly reported symptoms in menopausal women, affecting approximately 73% of women [1]. It has been suggested that vasomotor symptoms are triggered by a small elevation of core body temperature above the narrowed thermoneutral zone [2]. This central me...

The modulating effects of ascorbic acid (AA), vitamin E (E), and a combination of AA and E (AA + E) against eight-hour road transportation stress were investigated in 120 pullets during the hot-dry season. The result obtained showed that handling, loading and transportation induced lymphopenia, neutrophilia, liveweight loss, and mortality, which was alleviated by oral administration of AA, E, a...

The effect of solvation on the adsorption of organic molecules on graphite at room temperature has been addressed with force-field molecular dynamics simulations. As a model system, the solvation of a bis(terpyridine) isomer in water and 1,2,4-trichlorobenzene was studied with an explicit solvation model. The inclusion of solvation has a noticeable effect on adsorption energies. Although the re...
