Senolytic treatment attenuates immune cell infiltration without improving IAV outcomes in aged mice.

Aging is a major risk factor for poor outcomes following respiratory infections. In animal models, the most severe outcomes of respiratory infections in older hosts have been associated with an increased burden of senescent cells that accumulate over time with age and create a hyperinflammatory response. Although studies using coronavirus animal models have demonstrated that removal of senescent cells with senolytics, a class of drugs that selectively kills senescent cells, resulted in reduced lung damage and increased survival, little is known about the role that senescent cells play in the outcome of influenza A viral (IAV) infections in aged mice.

Deficiency of mitophagy mediator Parkin in aortic smooth muscle cells exacerbates abdominal aortic aneurysm.

Abdominal aortic aneurysms (AAAs) are a degenerative aortic disease and associated with hallmarks of aging, such as mitophagy. Despite this, the exact associations among mitophagy, aging, and AAA progression remain unknown. In our study, gene expression analysis of human AAA tissue revealed downregulation of mitophagy pathways, mitochondrial structure, and function-related proteins.

Inhibition of Cellular MEK/ERK Signaling Suppresses Murine Papillomavirus Type 1 Replicative Activities and Promotes Tumor Regression.

Unlabelled: Human papillomaviruses (HPVs) are a significant public health concern due to their widespread transmission, morbidity, and oncogenic potential. Despite efficacious vaccines, millions of unvaccinated individuals and those with existing infections will develop HPV-related diseases for the next two decades. The continuing burden of HPV-related diseases is exacerbated by the lack of effective therapies or cures for most infections, highlighting the need to identify and develop antivirals.

[A structural method to assess the course of the SARS-CoV-2 pandemic in school environmentsMétodo estructural para examinar el curso de la pandemia por el SARS-CoV-2 en ambientes escolares].

The COVID-19 pandemic has imposed several dilemmas for managers in the public sector, with school reopening being among the most complex decisions. The present article presents a microsimulation model of the pandemic course considering various scenarios within the confines of a classroom in the city of Belo Horizonte, Brazil. For that, a susceptible-infectious-recovered (SIR) model was integrated with a random graph model, associating epidemiological characteristics with sociometric and sociodemographic factors.

MEK/ERK signaling is a critical regulator of high-risk human papillomavirus oncogene expression revealing therapeutic targets for HPV-induced tumors.

Intracellular pathogens have evolved to utilize normal cellular processes to complete their replicative cycles. Pathogens that interface with proliferative cell signaling pathways risk infections that can lead to cancers, but the factors that influence malignant outcomes are incompletely understood. Human papillomaviruses (HPVs) predominantly cause benign hyperplasia in stratifying epithelial tissues.

Complete Genome of Salmonella enterica Serovar Typhimurium T5-Like Siphophage Stitch.

Salmonellosis, caused by Salmonella, is a leading cause of food poisoning worldwide. With the continuing rise of bacterial antibiotic resistance, efforts are focused on seeking new approaches for treatment of bacterial infections, namely, bacteriophage therapy. Here, we report the complete genome of S.

Complete Genome of Citrobacter freundii Siphophage Stevie.

Citrobacter freundii is an opportunistic pathogen responsible for many urinary tract infections acquired in hospitals and is thus a concern for public health. C. freundii phage Stevie might prove beneficial as a treatment against these infections.

Complete Genome Sequence of Citrobacter freundii Myophage Moon.

Citrobacter freundii and other Gram-negative opportunistic pathogens necessitate concern from the public health sector. Bacteriophages that kill such pathogens may be useful in the control and containment of these infections. Here, we describe the genome of a newly isolated T4-like myophage of C.

Complete Genome Sequence of Citrobacter freundii Myophage Moogle.

Citrobacter freundii is an opportunistic pathogen that has been linked to nosocomial infections, such as brain abscesses and pneumonia. Further study on phages infecting C. freundii may provide therapeutics for these infections.

Complete Genome Sequence of Citrobacter freundii Myophage Miller.

Citrobacter freundii is a Gram-negative, opportunistic pathogen that can be fatal to newborns or immunocompromised patients. Bacteriophages against this bacterium can be useful for therapeutic purposes. Here, we describe the complete genome and the key features of the pseudo T-even C.

Complete Genome of Salmonella enterica Serovar Enteritidis Myophage Marshall.

Salmonella enterica serovar Enteritidis is a food-borne pathogen that causes salmonellosis in the United States. Bacteriophages are emerging as viable biocontrol agents against this pathogen. Here, we present the complete annotated genome sequence of Salmonella Enteritidis T4-like myophage Marshall, which has potential as a phage therapy agent.

Collagen-PVP, a collagen synthesis modulator, decreases intraperitoneal adhesions.

Background: Adhesion formation in the peritoneal cavity is the most common cause of intestinal obstruction and secondary female infertility. A great effort has been dedicated to reduce adhesion formation because of the associated morbidity and its complications.

Materials And Methods: This study was designed as a before-after comparative trial and included 14 rabbits, with a weight between 300 and 500 g.
