The Product Quality Research Institute, in conjunction with the Food and Drug Administration, conducted an anonymous, electronic survey of the biological products manufacturing industry inspected by Team Biologics, with emphasis in obtaining industry input on inspection and compliance aspects of program operations. Representatives from all of the product-specific manufacturing industries inspected under the Team Biologics Program responded to this survey (vaccines; fractionated plasma proteins and recombinant analogs; allergenics; therapeutics and in-vivo diagnostics; and in-vitro diagnostics, including blood grouping reagents). Data and written feedback was obtained regarding each firm's interactions and experiences of Team Biologics inspections at its facilities over the past three years. The three areas most impacted by Team Biologic inspections were "Production and Process Controls", "Failure Investigations" and "Facility / Equipment Controls". Overall assessment of the program was generally positive with 68% identifying a positive impact on the sites operations and 88% assessed the inspections as being conducted fairly. The findings and conclusions of this report will be utilized by the FDA to evaluate and further assess the impact of the Team Biologics Program and to implement any necessary changes. This report provides useful information to companies currently manufacturing licensed biologic products subject to Team Biologics inspections and also to those companies anticipating these inspections for future product manufacturing.

The recent spread of SARS-CoV-2 has led to serious concerns about newly emerging infectious coronaviruses. Drug repurposing is a practical method for rapid development of antiviral agents. The viral spike protein of SARS-CoV-2 binds to its major receptor ACE2 to promote membrane fusion.

Effects of catechins with different structure characteristics on the structure and properties of gluten-catechin covalent complex were investigated, and the structure-activity relationship was further explored. Catechins including epicatechin (EC), epigallocatechin (EGC), epicatechin-3-gallate (ECG), and epigallocatechin-3-gallate (EGCG) could successfully covalently bind with gluten through C-N and/or C-S bonds. The physicochemical properties of covalent complex, including particle size, thermal stability, content of free amino groups, free sulfhydryl groups and disulfide bonds, were significantly affected by different catechins, and the action order was: EGCG > ECG > EGC > EC.

Background: The senescence of bone marrow mesenchymal stem cells (BMMSCs) is increasingly recognized as a critical factor contributing to the pathophysiology of age-related diseases. Recent studies suggest that small extracellular vesicles (sEVs) derived from the serum of elderly individuals may play a pivotal role in promoting BMMSC senescence. Glycoprotein non-metastatic melanoma protein B (GPNMB), a type I transmembrane glycoprotein, is upregulated during cellular senescence and can regulate stem cell ageing.

Background: Patients with knee osteoarthritis (KOA) often experience persistent pain and functional impairment after total knee arthroplasty (TKA), which presents challenges for pain management. Accurate preoperative assessment of pain characteristics is crucial for tailoring individualized treatment plans. The PainDETECT Questionnaire has been widely used to identify neuropathic components in chronic pain and has been validated for its reliability and validity across various cultural contexts.

Fat mass and obesity-associated protein (FTO) was the first m6A demethylase identified, which is responsible for eliminating m6A modifications in target RNAs. While it is well-established that numerous cytosolic and nuclear proteins undergo O-GlcNAcylation, the possibility of FTO being O-GlcNAcylated and its functional implications remain unclear. This study found that a negative correlation between FTO expression and O-GlcNAcylation in patients with myelodysplastic syndrome (MDS) and acute myeloid leukemia (AML).
