Copper Super-Dosing Improves Performance of Heat-Stressed Broiler Chickens through Modulation of Expression of Proinflammatory Cytokine Genes.

Continuous exposure to high ambient temperatures brings about a number of oxidative damages in chickens. Copper (Cu), an active component of a number of antioxidative defence components, should arrest these changes to take place although that may not be possible under the standard dosing regimen followed by the industry. To ascertain the optimum dose response that may be beneficial in sustaining the performance of chickens under heat stress (HS), broiler chickens ( = 400) were exposed to high ambient temperature (between 27.

Understanding the role of DNA polymerase λ gene in different growth and developmental stages of Oryza sativa L. indica rice cultivars.

DNA polymerase λ (Pol λ) is the only member of DNA polymerase family X present in plants. The enzyme is ddNTP sensitive as it contains the conserved C-terminal Pol β domain. The 1.
