Clearance of Intracellular Pathogens with Hyaluronic Acid Nanomicelles Responsive to HS and pH.

Hyaluronic acid (HA) is an acidic mucopolysaccharide of animal origin composed of repeating disaccharide units of N-acetylglucosamine and glucuronic acid. Due to its excellent biocompatibility, biodegradability, and selective affinity for CD44 receptors on cell surfaces, HA is widely employed as a drug carrier. In our study, we aimed to target subcellular bacteria by grafting cystamine onto HA scaffolds through an amide reaction, producing a linker responsive to HS and pH changes.

Unraveling the discrepancies between REDUCE-IT and STRENGTH trials with omega-3 fatty acids: new analytical approaches.

Two large-scale, randomized, double-blind, placebo-controlled trials-REDUCE-IT and STRENGTH-have garnered significant attention in cardiovascular medicine. Both trials aimed to evaluate the effects of prolonged administration of nutritional lipids, specifically omega-3 fatty acids, on major adverse cardiovascular events (MACEs) in high-risk patients undergoing statin therapy. REDUCE-IT used eicosapentaenoic acid (EPA) ethyl ester with mineral oil as a control, while STRENGTH utilized a carboxylic acid formulation of both EPA and docosahexaenoic acid (DHA) with corn oil as a control.

Decomposition based neural dynamics for portfolio management with tradeoffs of risks and profits under transaction costs.

Real-time online optimisation plays a crucial role in high-frequency trading (HFT) strategies. The Markowitz model, as a Nobel Prize-winning framework, is widely used for portfolio management optimisation by framing the problem as a constrained quadratic programming task. While conventional analytical methods are typically effective for solving quadratic programming problems with linear constraints, the introduction of both linear equality and inequality constraints in the Markowitz model necessitates the use of numerical methods.

Single-cell RNA-seq offer new insights into the cell fate decision of the primordial germ cells.

The faithful production of primordial germ cells (PGCs) in vitro opens a wide range of novel applications in reproductive biology and medicine. However, the reproducibility of PGCs culture conditions across different laboratories or breeds remains a challenge. Therefore, it is necessary to research the molecular dynamics that lead to the gradual establishment of cultured PGCs lines network.

Calcineurin: An essential regulator of sleep revealed by biochemical, chemical biological, and genetic approaches.

Research into mechanisms underlying sleep traditionally relies on electrophysiology and genetics. Because sleep can only be measured on whole animals by behavioral observations and physical means, no sleep research was initiated by biochemical and chemical biological approaches. We used phosphorylation sites of kinases important for sleep as targets for biochemical and chemical biological approaches.

Arctiin alleviates knee osteoarthritis by suppressing chondrocyte oxidative stress induced by accumulated iron via AKT/NRF2/HO-1 signaling pathway.

Iron overload (IO) was considered to be a risk factor for cartilage degradation in knee osteoarthritis (KOA) advancement. However, few drugs were found to improve cartilage degeneration by alleviating multiple cell death induced by the impaired iron level of the knee joints. We aimed to elucidate that Arctiin (ARC) plays a role in managing KOA caused by accumulated iron levels by restoring chondrocyte apoptosis and ferroptosis.
