Histone post-translational modifications (PTMs) regulate gene expression patterns through epigenetic mechanisms. The 5 histone proteins (H1, H2A, H2B, H3, and H4) are extensively modified, with over 75 distinct modification types spanning more than 200 sites. Despite strong advances in mass spectrometry-based approaches, identification and quantification of modified histone peptides remains challenging due to factors such as isobaric peptides, pseudo-isobaric PTMs, and low stoichiometry of certain marks.

Intractable infected wound caused by drug-resistant bacteria remains a severe healthcare problem. Reactive oxygen species (ROS)-based nanocatalytic therapy (ROS-NT) is harnessed to combat drug-resistant bacterial infection. However, it can also cause immune imbalance and excessive inflammatory responses, postponing subsequent wound healing process.

Doping with meclofenoxate, a nootropic stimulant prohibited in-competition by the World Anti-Doping Agency (WADA), is identified through the primary marker of urinary 4-chlorophenoxyacetic acid (4-CPA). However, the presence of 4-CPA can also arise from permissible sources. This study ventured into comparing urinary excretion patterns among exposures to permitted chemicals (chlorphenesin and 4-CPA) and the banned stimulant (meclofenoxate) and interpreting the analytical findings according to the reporting requirements.

Wastewater analysis technology has emerged as a promising tool for monitoring illicit drug consumption. However, the current reliance on the solid-phase extraction (SPE) pre-treatment method presents significant challenges for widespread adoption and high-throughput monitoring, as it consumes a large amount of time and labor as well as requires specialized instruments. This study has developed a direct injection (DI) technique for UPLC-MS/MS, enabling the detection of 77 compounds encompassing metabolites of human biomarkers, illicit drugs, and new psychoactive substances.

Natural products (NPs) play an important role in drug discovery and drug development due to their diverse chemical properties and biological activities. In the present work, an on-line capillary electrophoresis (CE) method was developed and applied to screen protein tyrosine phosphatase 1B (PTP1B) inhibitors in NPs. As a generic technique, transverse diffusion of laminar flow profiles (TDLFP) was utilized to mix all reactants in the capillary for on-line enzymatic reaction.

Background: Current donor risk assessments to identify risk of infectious transmission through transplantation have been criticized as unnecessarily discriminatory for sexual and gender minorities. Little is known about how increased infectious risk donor (IIRD) patients transition through the deceased donation system. We sought to evaluate how IIRD status and other equity-relevant identities impacted the likelihood of a caregiver of a deceased donor being approached for organ donation and the likelihood of caregiver consent.

To extend the short half-life of fluorouracil (Fu), enhance its tumor targeting, improve efficacy, and reduce side effects, providing a new approach for colorectal cancer treatment. Fluorouracil was hydroxylated and conjugated with methotrexate to form a 5-fluorouracil-methotrexate conjugate (MF). This was complexed with sulfobutyl ether-β-cyclodextrin (MF-SEBCD) using a stirring method to create an injectable formulation.

Alzheimer's disease (AD) is a multifactorial neurodegenerative disorder of complex pathogenesis and multiple interacting signaling pathways where amyloidal-β protein (Aβ) clearance plays a crucial role in cognitive decline. Herein, the current study investigated the possible modulatory effects of memantine/ rosuvastatin therapy on TGF-β1/p-Smad/p21 signaling pathway and their correlation to the blood brain barrier transporters involved in Aβ-clearance and microRNAs as a novel molecular mechanism in AD treatment. AD was induced by a single intracerebroventricular streptozotocin injection (ICV-STZ, 3 mg/kg) in rats and drug therapy was continued for 28 days after AD induction.

Methotrexate injections intralesionally as a treatment for psoriatic nails proved to be effective in large-scale studies as well as individual case reports, but the process is painful and time-consuming. The objective of this study was to compare the efficacy and safety of combined fractional CO2 laser (Fr. CO2) 10,600 nm and methotrexate gel versus methotrexate 1% gel alone in treatment of nail psoriasis.

Aims/introduction: This study aimed to evaluate and compare the effectiveness of oral semaglutide after adding to or switching from incretin-related drugs by assessing the changes in HbA1c and body weight (BW) in participants with type 2 diabetes in clinical settings.
Materials And Methods: A total of 368 participants were divided into groups according to antidiabetic medications before oral semaglutide treatment; incretin-related drug-naïve (naïve), switching from dipeptidyl peptide-4 inhibitors (DPP-4i) or glucagon-like peptide-1 receptor agonist (GLP-1 RA) groups. Adjusted mean changes in HbA1c and BW at 6 months after oral semaglutide administration were compared among the three groups.

Background: People who inject drugs (PWID) are at high risk of blood-borne infections, and injection drug use contributes significantly to hepatitis C virus (HCV) transmission. The WHO has therefore set targets of reducing HCV incidence and prevalence among PWID and increasing treatment coverage to eliminate HCV by 2030. The DRUCK study (2011-2014) found high HCV prevalence and low treatment coverage among PWID in Germany.

Osteoarthritis (OA) is the most common disease in aging joints and has characteristics of cartilage destruction and inflammation. It is currently considered a metabolic disease, and the CH25H-CYP7B1-RORα axis of cholesterol metabolism in chondrocytes plays a crucial catabolic regulatory role in its pathogenesis. Targeting of this axis in chondrocytes may provide a therapeutic approach for OA treatment.

Background: We aimed to identify motivators for people who inject drugs to pursue treatment for hepatitis C virus (HCV) infection and uncover opportunities that could make treatment more appealing.
Methods: Between November 2023 and January 2024, we conducted semi-structured interviews with 15 HCV RNA-positive individuals with a history of injecting drug use and self-reported as either untreated or treated but delayed treatment for more than 6 months. Thematic and framework data analysis was employed and interpreted using the Capability, Opportunity and Motivation (COM-B) framework of behaviour change.
