Свободноживущая почвенная нематода Caenorhabditis elegans (C. elegans) используется в качестве модельного организма в биологических исследованиях с середины 1960-х годов. Преимуществами C. elegans как экспериментальной модели для изучения биологии Metazoa являются короткий жизненный цикл, маленькие ...

An experiment was designed to study the modulatory effects of supplemental taurine on circadian rhythms of heat-associated cytokines in male broiler chickens of different ages under hot-dry conditions. Twenty, 21-day-old Arbor Acre male broiler chickens balanced for weight served as subjects and...
