Phase II randomized study of dostarlimab alone or with bevacizumab versus non-platinum chemotherapy in recurrent gynecological clear cell carcinoma (DOVE/APGOT-OV7/ENGOT-ov80).

Background: Recurrent gynecological clear cell carcinoma (rGCCC) has a low objective response rate (ORR) to chemotherapy. Previous preclinical and clinical data suggest a potential synergy between immune checkpoint inhibitors and bevacizumab in rGCCC. Dostarlimab, a humanized monoclonal antibody targeting programmed cell death protein 1 (PD-1), combined with the anti-angiogenic bevacizumab, presents a novel therapeutic approach.

Trabecular bone scores in children with osteogenesis imperfecta respond differently to bisphosphonate treatment depending on disease severity.

Introduction: Osteogenesis imperfecta (OI) is a congenital skeletal disorder characterized by bone fragility. Bisphosphonates (BISs) have become the mainstream treatment in children with OI. However, an optimal treatment protocol has not yet been established, while BIS treatment tends to be administered to normalize bone mineral density (BMD).

Prediction of new-onset atrial fibrillation in patients with hypertrophic cardiomyopathy using machine learning.

Aims: Atrial fibrillation (AF) is the most common sustained arrhythmia among patients with hypertrophic cardiomyopathy (HCM), leading to increased symptom burden and risk of thromboembolism. The HCM-AF score was developed to predict new-onset AF in patients with HCM, though sensitivity and specificity of this conventional tool are limited. Thus, there is a need for more accurate tools to predict new-onset AF in HCM.

Binding of a potential antibacterial drug, mangiferin, to serine hydroxymethyltransferase from Enterococcus faecium.

Serine hydroxymethyltransferase (SHMT) plays a critical role in the 1C metabolism pathway. This pathway is involved in the synthesis of many amino and nucleic acids, and SHMT is considered a target for drugs through folate metabolism, especially for cancer and malaria. A detailed analysis of the interactions between SHMTs and drugs will greatly contribute to the development of new drugs.

Identification of a novel imidazole-derived GABA agonist isopropoxate: simultaneous detection and quantification of imidazole-derived analogs from human hairs in abused cases by LC-MS/MS.

Purpose: Distribution and abuse of imidazole-derived γ-aminobutyric acid (GABA) agonists, such as etomidate and metomidate, and their analogs have been encountered frequently especially in China. The aim of this study was to identify etomidate, metomidate, propoxate, and isopropoxate more accurately by establishing a gas chromatography-mass spectrometry (GC-MS) and liquid chromatography tandem mass spectrometry (LC-MS/MS) method and applying it to real forensic cases.

Methods: One mg of the seized powder was dissolved in 1 mL of methanol, and subjected to GC-MS and LC-MS/MS.
