In this study, we present a novel catalyst-free energy transfer mediated radical rearrangement strategy for the aryl-heterofunctionalization of unactivated alkynes, leading to the synthesis of polyfunctional olefins with exceptional stereoselectivity. This innovative approach, driven by visible light, exemplifies green chemistry principles by eliminating the reliance on transition metals, external oxidants, and photocatalysts. The broad applicability of our method is demonstrated through the successful synthesis of a diverse array of compounds, including vinyl sulfones, vinyl selenides, and vinyl sulfides.

While brain resident immune cell-mediated neuroinflammation and peripheral immune cell (eg, T cell) infiltration into the brain have been shown to significantly contribute to Alzheimer's disease (AD) pathology, the nature and extent of immune responses in the brain in the context of AD and related dementias (ADRD) remain unclear. Furthermore, the roles of the peripheral immune system in driving ADRD pathology remain incompletely elucidated.

The HEV open reading frames (ORF1) encodes a large non-structural protein essential for viral replication, which contains several functional domains, including helicase and RNA-dependent RNA polymerase. A confusing aspect is that, while RNA viruses typically encode large polyproteins that rely on their enzymatic activity for processing into functional units, the processing of the ORF1 protein and the mechanisms involved remain unclear.

Here, our study first analyzed the main pharmacological components in Shen Ling Bai Zhu San n-butanol extracts (S-Nb), and then explored whether S-Nb administrated immune response of ILC3s, and how it regulates ILC3s. Shen Ling Bai Zhu San (SLBZS) or S-Nb were administrated for 7 days to analyze the frequency of ILC3s and their produced cytokine.

Background The growing population of male adolescent and young adult (AYA, 15-40 years old) cancer survivors has heightened interest in their reproductive health. However, studies have reported conflicting findings on the potential risks of cancer and its treatments on birth and obstetric outcomes. Methods We utilized encrypted identification numbers for both fathers and mothers to link three nationwide Taiwan datasets from 2004 to 2019, identifying 3,785 births with a paternal history of AYA cancer.

This study introduced GAPPA, a novel GNN-based approach, to predict post-ADX outcomes in patients with unilateral primary aldosteronism (UPA). The objective was to leverage the intricate dependencies between clinico-biochemical features and clinical outcomes using GNNs integrated into a bipartite graph structure to enhance prognostic prediction accuracy.

This study analyzed the incidence of postoperative rhinosinusitis, the associated risk factors, microbial species, and antibiotic usage in patients who underwent EEA.
Methods: Patients who underwent EEAs at a tertiary referral hospital between July 2015 and May 2019 were retrospectively evaluated.
Angelman syndrome (AS) is a rare genetic neurodevelopmental disorder with profoundly debilitating symptoms with no FDA-approved cure or therapeutic. Brain-derived neurotrophic factor (BDNF), and its receptor tropomyosin receptor kinase B (TrkB), have a well-established role as regulators of synaptic plasticity, dendritic outgrowth and spine formation. Previously, we reported that the association of postsynaptic density protein 95 (PSD-95) with TrkB is critical for intact BDNF signaling in the AS mouse model, as illustrated by attenuated PLCγ and PI3K signaling and intact MAPK pathway signaling.

The occurrence and development of cancer involves the participation of many factors, its pathological mechanism is far more complicated than other diseases, and the treatment is also extremely difficult. Although the treatment of cancer adopts diversified methods to improve the survival rate and quality of life of patients, but the drug resistance, metastasis and recurrence of cancer cause most patients to fail in treatment. Therefore, exploring new molecular targets in cancer pathology is of great value for improving and preventing the treatment of cancer.

We evaluated the impact of age at HBsAg seroclearance on long-term outcomes, along with how coexisting factors modified risks and life expectancy in CHB patients.
Methods: We used multi-state modeling approach to examine transitions through the CHB continuum in a longitudinal cohort study of male civil servants recruited in 1989-1992.
Polyurethane foam (PUF) pads are widely used in semiconductor manufacturing, particularly for chemical mechanical polishing (CMP). This study prepares PUF composites with microcrystalline cellulose (MCC) and nanocrystalline cellulose (NCC) to improve CMP performance. MCC and NCC were characterized using scanning electron microscopy (SEM) and X-ray diffraction (XRD), showing average diameters of 129.

Studies have shown that histone lactylation plays a role in the progression of liver-related diseases. Therefore, it is essential to explore lactylation-related gene (LRGs) biomarkers in HBV-ALF to provide new information for the treatment of HBV-ALF.

This systematic review and meta-analysis aimed to evaluate the current epidemiology of sarcopenia in Asia using the 2019 Asian Working Group for Sarcopenia (AWGS) diagnostic criteria.
Methods: Databases including PubMed, Embase, Web of Science, and Cochrane were systematically searched for studies published until December 7, 2023, involving older adults aged ≥ 60 years diagnosed with sarcopenia using the 2019 AWGS criteria in Asia.
Purpose: The innate immune response, particularly the reaction of polymorphonuclear neutrophils (PMNs), is crucial in shaping the outcomes of chronic inflammation, fibrosis, or osseointegration following biomaterial implantation. Peri-implantitis or peri-mucositis, inflammatory conditions linked to dental implants, pose a significant threat to implant success. We developed a single-cell analysis approach using a murine model to assess the immune response to implant materials, offering a practical screening tool for potential dental implants.

Aim: To examine the dynamic change in hepatic steatosis status during repeated assessments over time, and its potential impact on the risk of developing cardiovascular disease (CVD).
Methods: We assessed trajectories of hepatic steatosis and other metabolic disorders in 3134 middle-aged adults undergoing longitudinal assessment of ultrasonography during a pre-baseline period (1993-2009) in a population-based cohort study of liver health. Subsequently, we determined the association of hepatic steatosis trajectories with the incidence of CVD among 2185 CVD-free individuals, followed until 2021.
The Short Bowel Syndrome (SBS) Registry (NCT01990040) is a multinational real-world study evaluating the long-term safety of teduglutide in patients with SBS and intestinal failure (SBS-IF) in routine clinical practice. This paper describes the study methodology and baseline characteristics of adult patients who have (ever-treated) or have never (never-treated) received teduglutide. A total of 1411 adult patients (679 ever-treated; 732 never-treated) were enrolled at 124 sites across 17 countries.
