Corn is one of the staple food and feed ingredients in China, therefore its storage is of particular importance. Corn is typically stored for 2 or more years in national barns before it is sold as a food or feed ingredient. However, the effects of stored corn in national barns on the animal performance and nutrient utilization have not been investigated thus far. This study attempted to determine the effects of storage time on the chemical and physical characteristics of corn and its nutritional value, broiler growth performance, and meat quality...

The oxidative study has always been particularly topical in poultry science. However, little information about the occurrence of cellular apoptosis and autophagy through the reactive oxygen species (ROS) generation in nuclear factor-κB (NF-κB) signal pathway was reported in the liver of broilers exposed to hydrogen peroxide (H2O2). So we investigated the change of growth performance of broilers exposed to H2O2 and further explored the occurrence of apoptosis and autophagy, as well as the expression of NF-κB in these signaling pathways in the liver...

There are many facets of varicella zoster virus (VZV) pathogenesis that are not fully understood, such as the mechanisms involved in the establishment of lifelong latency, reactivation and development of serious conditions such as post herpetic neuralgia (PHN). Virus-encoded modulation of apoptosis has been suggested to play an important role in these processes. VZV open reading frame (ORF) 63 has been shown to modulate apoptosis in a cell type specific manner, but the impact of ORF63 on cell death pathways has not been examined in isolation, in the context of human cells...

Varicella-zoster virus (VZV) is the etiologic agent of varicella (chicken pox), a childhood exanthematic disease that develops as a result of primary infection, and zoster (shingles), caused by reactivation of the virus persisting in a latent form in the dorsal sensory ganglia. Although varicella is generally a mild self-limiting illness, in immunocompromised subjects and adults it can have a serious clinical course that can lead to permanent damage of the central nervous system. In these and in most zoster cases, treatment with anti-herpetic drugs and/or immunotherapy is necessary...
