Enhancing drug solubility through competitive adsorption on silica nanosurfaces with ultrahigh silanol densities.

We develop a technology based on competitive adsorption between drug molecules and water, specifically designed to address the critical issue of poor drug solubility. By specially engineering silica nanosurfaces with ultrahigh densities of silanol, we significantly enhance their affinity for both drug molecules and water, with a notably greater increase in water affinity. Such surfaces can effectively adsorb a variety of drug molecules under dry conditions.

Bimetallic metal-organic frameworks as electrode modifiers for enhanced electrochemical sensing of chloramphenicol.

An electrochemical sensor is presented for the detection of the chloramphenicol (CAP) based on a bimetallic MIL-101(Fe/Co) MOF electrocatalyst. The MIL-101(Fe/Co) was prepared by utilizing mixed-valence Fe (III) and Co (II) as metal nodes and terephthalic acid as ligands with a simple hydrothermal method and characterized by SEM, TEM, XRD, FTIR, and XPS. Electrochemical measurements such as electrochemical impedance spectroscopy (EIS), cyclic voltammetry (CV), and differential pulse voltammetry (DPV) showed that bimetallic MIL-101(Fe/Co) had the faster electron transfer, larger electroactive area, and higher electrocatalytic activity compared with  their monometallic counterparts due to the strong synergistic effect between bimetals.

MA104 cell line is permissive for human bocavirus 1 infection.

Human bocavirus 1 (HBoV1) has appeared as an emerging pathogen, causing mild to life-threatening respiratory tract infections, acute otitis media, and encephalitis in young children and immunocompromised individuals. The lack of cell lines suitable for culturing replicative viruses hinders research on HBoV1. Here, we characterized the susceptibility to HBoV1 of 29 human and 7 animal cell lines, and identified a permissive cell line, MA104.

Gabexate mesylate thermo-sensitive in-situ gel is effective for treating grade-III pancreatic trauma in beagle dogs guided by contrast-enhanced ultrasound.

Background: This study evaluates the efficacy of gabexate mesylate thermosensitive in-situ gel (GMTI) in the treatment of beagle grade III pancreatic trauma (PT) with the assistance of contrast-enhanced ultrasound (CEUS) and investigates its mechanism of action.

Methods: A grade III PT model consisting of 15 beagle dogs with severed main pancreatic ducts was created and treated with cephalic vein injection of gabexate mesylate (GM) (1.54 mL/10 kg, TID) and peripancreatic injection of GMTI (4.
