Comparison of Sulfamethoxazole Removal Efficiency Using Polyethersulfone Ultrafiltration Membrane Modified by Various Methods.
Materials (Basel)
December 2024
Department of Chemical Engineering, Faculty of Chemistry, Campus of Espinardo, University of Murcia, 30100 Murcia, Spain.
Nowadays, there is a growing interest in membrane modification processes to improve their characteristics and the effectiveness of their treatments and reduce the possible fouling. In this sense, in this work, a modification of an ultrafiltration membrane with three different materials has been carried out: reduced graphene oxide (rGO), chitosan and MgCl. For both the native and the modified membranes, a study has been carried out to remove the emerging contaminant sulfamethoxazole (SMX).

Background And Aims: Pancreatitis is the most common serious adverse event associated with endoscopic retrograde cholangiopancreatography (ERCP). This meta-analysis aimed to precisely assess the risk factors for post-ERCP pancreatitis (PEP).
Methods: We searched electronic databases for studies that assessed risk factors for PEP after adjusting for ≥3 risk factors, including at least one pre-specified patient-related and one procedure-related risk factor, and reported the data as adjusted odds ratios (OR) with 95% confidence intervals.
Pathologically altered articular cartilage attracts intense chondrocyte invasion into the extracellular matrix: in vitro pilot study.
Knee Surg Relat Res
December 2024
National Medical Research Radiological Center of the Ministry of Health of the Russian Federation, Koroleva st. 4, 249036, Obninsk, Russia.
Background: Due to non-vascularized and aneural structure, articular cartilage has limited self-repairing capacity. The aim of this study was to investigate the revitalization of inflammatory injured articular cartilage matrices by human nasal chondrocytes (hNC).
Materials And Methods: Cartilage matrix was prepared by devitalization of articular cartilage samples obtained intraoperatively from an adult patient undergoing knee joint replacement.
Structural basis of chiral wrap and T-segment capture by DNA gyrase.
Proc Natl Acad Sci U S A

Department of Molecular Microbiology, John Innes Centre, Norwich NR4 7UH, United Kingdom.
Type II topoisomerase DNA gyrase transduces the energy of ATP hydrolysis into the negative supercoiling of DNA. The postulated catalytic mechanism involves stabilization of a chiral DNA loop followed by the passage of the T-segment through the temporarily cleaved G-segment resulting in sign inversion. The molecular basis for this is poorly understood as the chiral loop has never been directly observed.

Article Synopsis
- Osteoporotic fractures are becoming more common in elderly people, particularly in diaphyseal locations on native bones, which are less frequent overall.
- Internal fixation methods must adapt due to changes in bone structure, requiring larger implants and specific types of screws to ensure stability and prevent further fractures.
- Nailing is primarily used for femoral and tibial fractures, and in cases involving the tibia or humerus, techniques that are gentle on soft tissue are essential to avoid complications in fragile skin.
