Traditional non-steroidal anti-inflammatory drugs (NSAIDs) and COX-2 selective inhibitors are among the most widely used drugs. However, their significant side effects in gastrointestinal and cardiovascular systems limited the use of these drugs. Recently, research and development of NO-donating NSAIDs (NO-NSAIDs) have become one of the most important strategies to reduce these side effects. NO-NSAIDs may exert a broad range of positive effects in terms of NO-mediated gastrointestinal and cardiovascular safety as well as comparable or increased anti-inflammatory, analgesic properties relative to NSAIDs. This review briefly deals with chemistry of NO-NSAIDs, more details are focused on biological significance, mechanism of action, and therapeutic potential of this novel class of drugs.

Coccidiosis, a parasitic disease caused by Eimeria protozoa that parasitizes intestinal tissues of chicken, poses a challenge to the development of the poultry industry. circRNAs are a class of circular RNA macromolecules crucial in the immune response to pathogens. Previous studies have shown that gga-miR-2954 inhibits the inflammatory response to Eimeria tenella (E.

Graph neural networks (GNNs) have shown great promise in modeling graph-structured data, but the over-smoothing problem restricts their effectiveness in deep layers. Two key weaknesses of existing research on deep GNN models are: (1) ignoring the beneficial aspects of intra-class smoothing while focusing solely on reducing inter-class smoothing, and (2) inefficient computation of residual weights that neglect the influence of neighboring nodes' distributions. To address these weaknesses, we propose a novel Smoothing Deceleration (SD) strategy to reduce the smoothing speed rate of nodes as information propagates between layers, thereby mitigating over-smoothing.

One key determinant of HIV-1 latency reversal is the activation of the viral long terminal repeat (LTR) by cellular transcription factors such as NF-κB and AP-1. Interestingly, the activity of these two transcription factors can be modulated by glucocorticoid receptors (GRs). Furthermore, the HIV-1 genome contains multiple binding sites for GRs.

Omadacycline is a novel antimicrobial belonging to the tetracycline class. It has the ability to evade both efflux and ribosomal methylation types of resistance and therefore has an expanded spectrum compared to other tetracycline agents. Omadacycline is active against a number of multidrug-resistant bacteria, including macrolide and doxycycline-resistant methicillin-resistant (MRSA), vancomycin-resistant Enterococcus, and several enteric gram-negative bacilli.

Engine deposits can reduce performance and increase emissions, particularly for modern direct-injection fuel delivery systems. Surfactants known as deposit control additives (DCAs) adsorb and self-assemble on the surface of deposit precursors to keep them suspended in the fuel. Here, we show how molecular simulations can be used to virtually screen the ability of surfactants to bind to polyaromatic hydrocarbons, comprising a major class of carbonaceous deposits.
