Rhodium(III)-catalyzed C-H bond functionalization for the synthesis of β-aryl aldehydes and ketones from (hetero)aryl oximes, pyri(mi)dine, as well as pyrazoles and α,β-unsaturated carbonyl compounds has been developed under exceedingly mild reaction conditions. Thus, the versatile rhodium(III) catalysis features high step- and atom-economy, oxidant-free reaction conditions, and broad substrate scope.

Objective: To investigate the clinical efficacy of thoracoscopic minimally invasive surgery with nickel-titanium shape memory alloy wrap bone plate versus rib periosteal internal fixation in patients with multiple rib fractures (MRF) and flail chest.
Methods: A retrospective analysis was performed on 100 patients with MRF and flail chest treated with thoracoscopic minimally invasive surgery and internal fixation with rib fracture preservation between January 2019 and December 2022, including 54 males and 46 females, aged from 20 to 65 years old, with an average age of (38.0±18.

The screening of glycoprotein markers has become an integral part of the in vitro diagnosis of malignant tumors. Herein, an electrochemical method based on alkaline phosphatase (ALP)-mediated enzymatic silver deposition is reported for the highly sensitive detection of glycoprotein tumor markers, in which ALP enzymes are decorated to the glycan moieties of targets via the lectin-carbohydrate interactions. As glycoproteins are conjugated with multiple glycan chains, lectin-mediated labeling can result in the decoration of each target with multiple ALP enzymes.

Department of Pediatrics, Traditional Chinese and Western Medicine Hospital of Wuhan, Tongji Medical College, Huazhong University of Science and Technology, Wuhan No.1 Hospital, Wuhan, China.
Objective: The objective of this study is to assess the impact of nano platinum-hydrogen saline (Pt NPs + H) on oxygen-induced retinopathy (OIR) in neonatal rats, with the goal to contribute new insights into the therapeutic strategies for retinopathy of prematurity.
Methods: Pt NPs + H formulation was synthesized to address OIR in a rat model. Subsequent examination included the assessment of retinal blood vessel distribution and morphology through hematoxylin and eosin (HE) and isolectin B4 (IB4) staining techniques.
Fractionation of High-Yield Noncondensed Lignin and Glucan Oligomers from Lignocellulose in a Novel Biphasic System.

Guangdong University of Technology, Guangzhou 510006, China.
Effective fractionation of lignocellulose into hemicellulose, cellulose, and lignin is the precondition for full-component valorization. Generally, harsh reaction conditions are used to improve fractionation efficiency, which leads to severe lignin condensation and inhibits its value-added applications. To address this issue, a novel biphasic system consisting of molten salt hydrates (MSHs) and n-butanol was developed for birch fractionation.

Epidithio-diketopiperazine (ETP) compound is the family of natural fungal metabolites that are known to exert diverse biological effects, such as immunosuppression and anti-cancer activity, in higher animals. However, an enzyme-like catalytic activity or function of the ETP derivatives has not been reported. Here, we report the generation of novel thiol peroxidase mimetics that possess peroxide-reducing activity through strategic derivatization of the core ETP ring structure.
