Diversity-oriented synthesis of stereodefined tetrasubstituted alkenes via a modular alkyne gem-addition strategy.

Stereocontrolled construction of tetrasubstituted olefins has been an attractive issue yet remains challenging for synthetic chemists. In this manuscript, alkynyl selenides, when treated with ArBCl, are subject to an exclusive 1,1-carboboration, affording tetrasubstituted alkenes with excellent levels of E-selectivity. Detailed mechanistic studies, supported by DFT calculations, elucidates the role of selenium in this 1,1-addition process.

Atomically thin high-entropy oxides via naked metal ion self-assembly for proton exchange membrane electrolysis.

Designing efficient Ruthenium-based catalysts as practical anodes is of critical importance in proton exchange membrane water electrolysis. Here, we develop a self-assembly technique to synthesize 1 nm-thick rutile-structured high-entropy oxides (RuIrFeCoCrO) from naked metal ions assembly and oxidation at air-molten salt interface. The RuIrFeCoCrO requires an overpotential of 185 mV at 10 m A cm and maintains the high activity for over 1000 h in an acidic electrolyte via the adsorption evolution mechanism.

Physical unclonable in-memory computing for simultaneous protecting private data and deep learning models.

Compute-in-memory based on resistive random-access memory has emerged as a promising technology for accelerating neural networks on edge devices. It can reduce frequent data transfers and improve energy efficiency. However, the nonvolatile nature of resistive memory raises concerns that stored weights can be easily extracted during computation.

SAA3 deficiency exacerbates intestinal fibrosis in DSS-induced IBD mouse model.

Intestinal fibrosis, as a late-stage complication of inflammatory bowel disease (IBD), leads to bowel obstruction and requires surgical intervention, significantly lowering the quality of life of affected patients. SAA3, a highly conserved member of the serum amyloid A (SAA) apolipoprotein family in mice, is synthesized primarily as an acute phase reactant in response to infection, inflammation and trauma. An increasing number of evidence suggests that SAA3 exerts a vital role in the fibrotic process, even though the underlying mechanisms are not yet fully comprehended.

Cathodic tandem alkylation/dearomatization of heterocycles enabled by Al-facilitated carbonyl deoxygenation.

Developing efficient strategies for the deoxygenative functionalization of carbonyl compounds is crucial for enhancing the effective utilization of biomass and the upgrading of chemical feedstocks. In this study, we present an elegant cathodic reduction strategy that enables a tandem alkylation/dearomatization reaction between quinoline derivatives and aryl aldehydes/ketones in a one-pot process. Our approach can be executed via two distinct paths: the aluminum (Al)-facilitated spin-center shift (SCS) path and the Al-facilitated direct deoxygenation path.

Highly printable, strong, and ductile ordered intermetallic alloy.

Ordered intermetallic alloys are renowned for their impressive mechanical, chemical, and physical properties, making them appealing for various fields. However, practical applications of them have long been severely hindered due to their severe brittleness and poor fabricability. It is difficult to fabricate such materials into components with complex geometries through traditional subtractive manufacturing methods.

Propolis mouthwashes efficacy in managing gingivitis and periodontitis: a systematic review of the latest findings.

Background And Objectives: Gingivitis and periodontitis are common periodontal diseases that can significantly harm overall oral health, affecting the teeth and their supporting tissues, along with the surrounding anatomical structures, and if left untreated, leading to the total destruction of the alveolar bone and the connective tissues, tooth loss, and other more serious systemic health issues. Numerous studies have shown that propolis can help reduce gum inflammation, inhibit the growth of pathogenic bacteria, and promote tissue regeneration, but with varying degrees of success reported. For this reason, this comprehensive systematic review aims at finding out the truth concerning the efficacy of propolis mouthwashes in treating gingivitis and periodontitis, as its main objective.

Adolescent mice exposed to TBI developed PD-like pathology in middle age.

Traumatic brain injury (TBI) is identified as a risk factor for Parkinson's disease (PD), which is a neurodegenerative disease characterized by the loss of dopaminergic neurons in the substantia nigra (SN). However, the precise mechanism by which chronic TBI initiates PD pathogenesis is not yet fully understood. In our present study, we assessed the chronic progression and pathogenesis of PD-like behavior at different intervals in TBI mice.

Supramolecular discrimination and diagnosis-guided treatment of intracellular bacteria.

Pathogenic intracellular bacteria pose a significant threat to global public health due to the barriers presented by host cells hindering the timely detection of hidden bacteria and the effective delivery of therapeutic agents. To address these challenges, we propose a tandem diagnosis-guided treatment paradigm. A supramolecular sensor array is developed for simple, rapid, accurate, and high-throughput identification of intracellular bacteria.

[Gastric adenocarcinoma complicated by subarachnoid hemorrhage and cerebral infarction: a rare case of Trousseau syndrome and literature review].

Trousseau's syndrome is a thromboembolic disorder associated with malignancies, with cerebral infarction and hemorrhage representing common central nervous system complications in patients with cancer. This report details the diagnosis and treatment of a patient with gastric adenocarcinoma at our institution who concurrently developed cerebral infarction and subarachnoid hemorrhage. We performed a comprehensive literature review in the Wanfang and PubMed databases, searching for relevant studies on Trousseau's syndrome, cerebral embolism, and subarachnoid hemorrhage.

[Analysis and prediction of the age-period-cohort model of disease burden of rheumatoid arthritis in China from 1990 to 2019].

Using the Global Burden of Disease Study 2019 (GBD 2019) database, the Joinpoint regression model was used to analyze the trend of rheumatoid arthritis (RA) incidence and the standardized disability-adjusted life years (DALY) rate in China. The age, period, and cohort effects were discussed based on the age-period-cohort model. The grey prediction model GM (1, 1) was used to fit the trend of incidence and the standardized DALY rate of RA and predict the incidence and standardized DALY rate of RA in China from 2020 to 2034.

[Efficacy and safety of transarterial chemoembolization combined with sintilimab and bevacizumab biosimilar for unresectable hepatocellular carcinoma].

To investigate the efficacy and safety of transarterial chemoembolization (TACE) combined with sintilimab and bevacizumab biosimilar in the treatment of unresectable hepatocellular careinoma (uHCC). The clinical data of 64 patients with unresectable HCC, who were admitted to the First Affiliated Hospital of Soochow University between January 2021 and December 2023, were retrospectively analyzed. The patients were divided into a combination group (=43, receiving TACE combined with sintilimab and bevacizumab biosimilar) and control group (=21, receiving only sintilimab and bevacizumab biosimilar).
