Engineered Drug-Amphiphile Conjugate Nanoparticles for Targeted Inhibition of AQP4-Mediated NLRP3 Inflammasome Signaling in Collagen-Induced Rheumatoid Arthritis.

Aquaporins (AQPs) are transmembrane proteins that transport water, small solutes, and molecules across cell membranes. Studies have reported the role of AQPs in the activation, migration, and proliferation of immune cells, thus modulating the pathogenesis of autoimmune disease. In joints, the enhanced AQP4 expression exaggerates pathological changes like hydrarthrosis, acidosis, and hyperosmotic stress-inducing dysfunction of the articular chondrocytes, leading to articular cartilage destruction in collagen-induced arthritis (CIA).

Thus, targeting these lesions at an early stage of the disease could impede the oncogenesis and maximize the efficacy. The present work underscores a combinatorial therapy of paclitaxel (PTX) and glycyrrhizin (GL) delivered via gelatin-derived core-shell nanoparticles [AC-PCL(GL + PTX)-GNPs] for effective management of precancerous lesions.

Fish gut microbiome and its application in aquaculture and biological conservation.

Understanding the diversity and function of fish gut microbiomes has advanced substantially, yet many aspects remain poorly understood, particularly the interplay among microbiota, host species, and environmental factors in the context of conservation. This review explores the composition and abundance of gut bacterial communities in key aquaculture fish groups-cyprinids, ictalurids (catfish), salmonids, and cichlids (tilapia)-alongside the model organism zebrafish, across diverse geographic regions. The findings highlight environmental habitats and host species as primary determinants of gut microbiome structure, offering a global perspective on these microbial communities.

Leveraging thiol-functionalized biomucoadhesive hybrid nanoliposome for local therapy of ulcerative colitis.

Directly administering medication to inflamed intestinal sites for treating ulcerative colitis (UC), poses significant challenges like retention time, absorption variability, side effects, drug stability, and non-specific delivery. Recent advancements in therapy to treat colitis aim to improve local drug availability that is enema therapy at the site of inflammation, thereby reducing systemic adverse effects. Nevertheless, a key limitation lies in enemas' inability to sustain medication in the colon due to rapid peristaltic movement, diarrhea, and poor local adherence.

Measurement of the Isolated Nuclear Two-Photon Decay in ^{72}Ge.

The nuclear two-photon or double-gamma (2γ) decay is a second-order electromagnetic process whereby a nucleus in an excited state emits two gamma rays simultaneously. To be able to directly measure the 2γ decay rate in the low-energy regime below the electron-positron pair-creation threshold, we combined the isochronous mode of a storage ring with Schottky resonant cavities. The newly developed technique can be applied to isomers with excitation energies down to ∼100  keV and half-lives as short as ∼10  ms.

Despite its unknown cause, advancements in understanding its pathophysiology have facilitated novel therapeutic approaches. Current treatments, including disease-modifying anti-rheumatic drugs (DMARDs) and biologics, often result in low efficacy and unnecessary side effects.

RNA editing in host lncRNAs as potential modulator in SARS-CoV-2 variants-host immune response dynamics.

Both host and viral RNA editing plays a crucial role in host's response to infection, yet our understanding of host RNA editing remains limited. In this study of in-house generated RNA sequencing (RNA-seq) data of 211 hospitalized COVID-19 patients with PreVOC, Delta, and Omicron variants, we observed a significant differential editing frequency and patterns in long non-coding RNAs (lncRNAs), with Delta group displaying lower RNA editing compared to PreVOC/Omicron patients. Notably, multiple transcripts of  and exhibited high editing frequencies.

Mitigating cognitive deficits with teriflunomide: unraveling PI3K-modulated behavioral outcomes in mice.

Background: Alzheimer's disease is a leading neurological disorder that gradually impairs memory and cognitive abilities, ultimately leading to the inability to perform even basic daily tasks.
