Effects of nano-selenium on cecum microbial community and metabolomics in chickens challenged with Ochratoxin A.

Introduction: Ochratoxin A (OTA) is a widely distributed mycotoxin. Nano-selenium (Nano-Se) is an emerging form of selenium known for its superior bioavailability, remarkable catalytic efficiency, and robust adsorbing capacity. Despite these characteristics, its impact on the microbial community and metabolomics in the cecum of chickens exposed to OTA has been infrequently investigated.

Effects of transport stress on the oxidative index, apoptosis and autophagy in the small intestine of caprine.

Background: Introducing new goat breeds or transferring adult goats from farms to slaughterhouses requires transportation, which can engender adverse effects, such as oxidative stress, pathological cell apoptosis and autophagy. Current evidence suggests that malondialdehyde (MDA) is a metabolite of lipid peroxidation during oxidative stress, while superoxide dismutase (SOD) and catalase (CAT) can alleviate injury caused by free radicals and reactive oxygen species (ROS). Meanwhile, Bcl-2, Bax, LC3B, PINK1 and Parkin are important proteins that participate in pathological cell apoptosis and autophagy.

Relationship of Noncoding RNA and Swine Viruses.

Background: Swine viruses are well known as a threat to the pig industry. Many signaling pathways and a number of proteins were discovered to participate in the immune responses to swine viruses. Noncoding RNAs (ncRNAs), comprising a different set of transcripts including housekeeping RNAs (for example, rRNAs and tRNAs) and regulatory RNAs (small RNAs and long ncRNAs), recently have been described as important regulators of viral infections regarding swine.

Protective and detoxifying effects conferred by selenium against mycotoxins and livestock viruses: A review.

Animal feed can easily be infected with molds during production and storage processes, and this can lead to the production of secondary metabolites, such as mycotoxins, which eventually threaten human and animal health. Furthermore, livestock production is also not free from viral infections. Under these conditions, the essential trace element, selenium (Se), can confer various biological benefits to humans and animals, especially due to its anticancer, antiviral, and antioxidant properties, as well as its ability to regulate immune responses.

Characterization of bat coronaviruses: a latent global threat.

It has been speculated that bats serve as reservoirs of a huge variety of emerging coronaviruses (CoVs) that have been responsible for severe havoc in human health systems as well as negatively affecting human economic and social systems. A prime example is the currently active severe acute respiratory syndrome (SARS)-CoV2, which presumably originated from bats, demonstrating that the risk of a new outbreak of bat coronavirus is always latent. Therefore, an in-depth investigation to better comprehend bat CoVs has become an important issue within the international community, a group that aims to attenuate the consequences of future outbreaks.

Detection of heat shock protein 27, 70, 90 expressions in primary parenchymatous organs of goats after transport stress by real-time PCR and ELISA.

Transport stress causes a series of problems to goat production, such as tissue injury and immunity damage. As a pro-survival pathway, the heat shock response protects healthy cells of goat from stressors. To evaluate the effects of transport stress on heat shock protein (HSPs) expression on goat primary parenchymatous organs, a total of three batches of goats were treated in this study.

Genome-wide analysis of long non-coding RNA expression profile in porcine circovirus 2-infected intestinal porcine epithelial cell line by RNA sequencing.

Porcine circovirus-associated disease (PCVAD), which is induced by porcine circovirus type 2 (PCV2), is responsible for severe economic losses. Recently, the role of noncoding RNAs, and in particular microRNAs, in PCV2 infection has received great attention. However, the role of long noncoding RNA (lncRNA) in PCV2 infection is unclear.
