Article Abstract
The search for promising biomolecules such as chitooligosaccharides (COS) has increased due to the need for healing products that act efficiently, avoiding complications resulting from exacerbated inflammation. Therefore, this study aimed to produce COS in two stages of hydrolysis using chitosanases derived from Additionally, this study aimed to structurally characterize the COS via mass spectrometry, to analyze their biocompatibility in acute toxicity models in vivo, to evaluate their healing action in a cell migration model in vitro, to analyze the anti-inflammatory activity in in vivo models of xylol-induced ear edema and zymosan-induced air pouch, and to assess the wound repair action in vivo. The structural characterization process pointed out the presence of hexamers. The in vitro and in vivo biocompatibility of COS was reaffirmed. The COS stimulated the fibroblast migration. In the in vivo inflammatory assays, COS showed an antiedematogenic response and significant reductions in leukocyte migration, cytokine release, and protein exudate. The COS healing effect in vivo was confirmed by the significant wound reduction after seven days of the experiment. These results indicated that the presence of hexamers influences the COS biological properties, which have potential uses in the pharmaceutical field due to their healing and anti-inflammatory action.

Discovery of Tricyclic Derivative as Novel and Potent Respiratory Syncytial Virus Fusion Glycoprotein Inhibitor with an Improved Pharmacokinetic Profile.

Respiratory syncytial virus (RSV) is a major pathogen causing acute respiratory infections, and the RSV fusion glycoprotein (F) has been identified as a key target for developing small-molecule inhibitors. Based on our prior identification of lonafarnib as an F protein inhibitor, medicinal chemistry efforts led to the development of , which exhibits significantly enhanced potency against both laboratory and clinical RSV isolates in cellular assays. Time-of-addition and SPR assays indicate that inhibits viral entry by targeting the RSV F protein, but has farnesyltransferase-independent antiviral efficacy.

Background: Allogeneic hematopoietic stem cell transplantation (allo-HCT) remains the only curative option for myelofibrosis (MF) but is often underutilized in patients aged ≥ 65 due to concerns about treatment-related toxicity.
Methods: We conducted a retrospective analysis of chronic-phase MF allo-HCT recipients using the publicly available CIBMTR P-5640 dataset (2008-2019). Key endpoints included overall survival (OS), disease-free survival (DFS), relapse, nonrelapse mortality (NRM), and graft-vs-host disease (GVHD)-related outcomes.

The diagnosis of hemolysis is still based on straightforward biochemical parameters: haptoglobin (the most sensitive), lactate dehydrogenase (LDH), and unconjugated bilirubin. Anemia is not always present. Reticulocyte counts typically exceed 120×10/L, except in cases of associated vitamin deficiency or during the very early phase of acute hemolysis.

Local anesthetics such as lidocaine have been used in humans and other animals to perform surgical procedures, therapeutics, and experiments. Lidocaine discarded into the environment through industrial waste, human and animal excretion, and household waste has been detected in the aquatic environment. For example, lidocaine in rivers, lakes, and influent and effluent water has been detected at wastewater treatment plants (7 ng/L-2.

The development of novel multijunction heterostructure photocatalysts is critical for the efficient degradation of organic pollutants, attributed to their ability to enhance the separation of photogenerated electron-hole pairs. In our study, a ternary composite, melem/BiVO/g-CN (BVO/CNMH), was synthesized via an acid-soaking method followed by calcination, using g-CN as a sacrificial precursor in the presence of BiVO. This approach yielded a porous, interconnected architecture in BVO/CNMH.
