Adenoid cystic carcinomas (AdCC) of salivary gland origin have long been categorized as fusion-defined carcinomas owing to the almost universal presence of the gene fusion MYB::NFIB, or less commonly MYBL1::NFIB. Sinonasal AdCC is an aggressive salivary gland malignancy with no effective systemic therapy. Therefore, it is urgent to search for potentially targetable genetic alterations associated with AdCC.

Coronavirus disease 2019 (COVID-19) is a highly contagious viral disease, caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). It can manifest as mild to severe flu-like and non-flu-like symptoms and signs, which are associated with immune dysfunction and increased mortality. The findings from COVID-19 patients imply a link between immune system abnormalities such as impaired T-cell responses or cytokine imbalances and increased risk for worse clinical outcomes, which has not been fully understood.

Background: Patients with systemic right ventricle (SRV), either d-transposition of the great arteries following an atrial switch procedure or congenitally corrected transposition of the great arteries, develop severe right ventricular dysfunction, prompting appropriate medical therapy. However, the efficacy of beta-blockers and angiotensin receptor blockers or angiotensin-converting enzyme inhibitors (ACEI) in SRV patients is unproven.

Objectives: The objective of this study was to determine the effects of ACEI/ARB and beta-blockers on outcomes in SRV patients after accounting for likely cofounders affecting their use.

Human activities result in sediment accumulation, so the reservoirs gradually lose their functionality, impacting their ability to manage large flood inflows, supply water, and generate hydroelectric power. Therefore, periodic removal of sediments from water reservoirs is essential to maintain functionality. Notwithstanding, the management of dredged sediments is a multifaceted process that involves careful consideration of environmental, regulatory, and economic factors to ensure their responsibility and sustainable handling.

This study aimed to determine the effect of complex training (CT) on post-activation performance enhancement (PAPE) effect magnitude, 5- and 30-m linear sprint, 5-0-5 change-of-direction (COD), back squat (BS) and hip thrust (HT) one-repetition maximum [1RM], and jumping performance (countermovement jump [CMJ], drop jump [DJ], and broad jump [BJ]). The PAPE effect was elicited before and after each intervention by 3 BS repetitions at 90% 1RM and verified by CMJ performance. Twenty-four soccer players were randomly and equally assigned to 6 weeks of either medium (MED; [65-70%1RM]) or high-intensity (HIGH; [80-85%1RM]) CT performed twice a week.

The central nervous system is a well-known steroidogenic tissue producing, among others, cholesterol metabolites such as neuroactive steroids, oxysterols and steroid hormones. It is well known that these endogenous molecules affect several receptor classes, including ionotropic GABAergic and NMDA glutamatergic receptors in neurons. It has been shown that also ionotropic purinergic (P2X) receptors are cholesterol metabolites' targets.

Retroviral gene transfer is the preferred method for stable, long-term integration of genetic material into cellular genomes, commonly used to generate chimeric antigen receptor (CAR)-T cells designed to target tumor antigens. However, the efficiency of retroviral gene transfer is often limited by low transduction rates due to low vector titers and electrostatic repulsion between viral particles and cellular membranes. To overcome these limitations, peptide nanofibrils (PNFs) can be applied as transduction enhancers.
