Transcriptomic Analysis Reveals Molecular Mechanisms Underpinning Mycovirus-Mediated Hypervirulence in <i>Beauveria bassiana</i> Infecting <i>Tenebrio molitor</i> by Charalampos Filippou, Robert H. A. Coutts, Ioly Kotta-Loizou, Sam El-Kamand, Alexie Papanicolaou

“…However, beauvericin, a mycotoxin capable of inducing oxidative stress at the molecular level, was expressed in all four isolates, indicating an important contribution to virulence against <i>T. molitor</i>. These observations suggest that detoxification of immune-related (oxidative) defenses and nutrient scouting, as mediated by these genes, occurs in mid-infection during the internal growth phase. …”

A Unique Trinucleotide-Bloc Mutation-Based Two SARS-CoV-2 Genotypes with Potential Pathogenic Impacts by Mustak Ibn Ayub

“…Although some mutations provide benefits to the virus against human immune response, others may result in their reduced pathogenicity and virulence. By analyzing more than 3000 high-coverage, complete sequences deposited in the GISAID database up to April 2020, here I report the uniqueness of the 28881–28883: GGG > AAC trinucleotide-bloc mutation in the SARS-CoV-2 genome that results in two substrains, described here as SARS-CoV-2g (28881–28883: GGG genotype) and SARS-CoV-2a (28881–28883: AAC genotype). …”

The dynamics of a delay model of hepatitis B virus infection with logistic hepatocyte growth by Steffen Eikenberry, Sarah Hews, John D. Nagy, Yang Kuang

“…We show that when thebasic reproductive number is greater than 1 there exists a biologically meaningfulchronic steady state, and the stability of this steady state is dependent upon boththe rate of hepatocyte regeneration and the virulence of the disease. When thechronic steady state is unstable, simulations show the existence of an attractingperiodic orbit. …”

Mechanism of Action of Lacticaseibacillus paracasei HNU502 and Fecal Microbiota Transplantation in Alleviating Antibiotic Side Effects by CHEN Lin, LI Ao, LI Jiahe, ZHANG Zeng, ZHANG Jiachao

“…Moreover, the two approaches ameliorated the metabolic disorders of short-chain fatty acids, inhibited the secretion of pro-inflammatory cytokines such as interleukin (IL)-1β, IL-6 and tumor necrosis factor (TNF)-α as well as blood urea nitrogen (BUN), and effectively reduced virulence factor enrichment. This study contributes to a better understanding of the link between human health and gut microbiota, and provides new therapeutic options for mitigating antibiotic side effects, which is of great significance for improving patients’ health status and quality of life.…”
