Optimization and Characterization of Aspirin‐ and Ibuprofen‐Loaded Lipid‐Based Nanoparticle Synthesis for Antibacterial Activity and Cytotoxic Effect

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Lipid‐based nanoparticles (LNPs) are favored for drug delivery because of their low toxicity, high biocompatibility, ability to self‐assemble into nanoparticles, and ability to enhance drug bioavailability, thereby improving drug release modulation and pharmacokinetics.

Magnetic Pinecone Biochar‐Activated Peroxymonosulfate for Efficient Sulfamethoxazole Degradation: Performance, Mechanism, and Toxicity Analysis

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT This study successfully prepared magnetic iron/cobalt codoped biochar catalyst (CFSBC) using a one‐step calcination method. The morphology and structure of the material were systematically characterized using SEM, XRD, FTIR, TEM, BET, Raman, VSM, and XPS techniques. The effects of key parameters such as catalyst dosage, peroxymonosulfate (PMS)

Dual Action of Dipyridamole in Experimental Rheumatoid Arthritis: Suppression of Joint Inflammation and Upregulation of Muscle Anabolism via Adenosine and AMPK pathways

Arthritis &Rheumatology, Accepted Article.
Introduction Rheumatoid sarcopenia, characterized by the progressive loss of skeletal muscle mass and function, is a frequent comorbidity in rheumatoid arthritis (RA), linked to prolonged, severe systemic inflammation. Purinergic signaling (adenosine, AMP, and ATP) plays a crucial role in inflammation, myogenesis, and muscle hypertrophy.

A New Era for Using Natural Pigments: The Case of the C50 Carotenoid Called Bacterioruberin

Biotechnology and Applied Biochemistry, EarlyView.
ABSTRACT Haloarchaea are extremophilic microorganisms belonging to the Archaea domain that require high salt concentrations to live, thus inhabiting ecosystems like salty ponds, salty marshes, or extremely salty lagoons. They are more abundant and widely distributed worldwide than initially expected.

A New Kinetic-Mechanistic Approach Towards Spectrophotometric Bioanalysis of 2-Phenylethylamine as a Sympathomimetic Agent Using Sodium Isopropyl Xanthate. [PDF]

Anal Sci Adv
ABSTRACT 2‐Phenylethylamine (2‐PEA), an aromatic biogenic amine, demonstrates significant physiological and toxicological effects on human health. A variety of conventional methods have been widely used for the determination of 2‐PEA. However, the necessity of complex sample preparation and high cost of instrumentation may pose challenges to their ...
