B cell dysfunction in thalamus and brainstem involvement and high lactate caused by novel mutation of EARS2 gene.

Purpose: The EARS2 gene, a member of the mt-aaRS family, encodes mitochondrial glutamyl-tRNA synthetase (GluRS), which is involved in the synthesis of mitochondrial proteins. Pathogenic defects in EARS2 may cause mitochondrial OXPHOS deficiency, which is associated with a rare autosomal-recessive mitochondrial disease, leukoencephalopathy with thalamus and brainstem involvement and high lactate (LTBL).

Methods: In this study, clinical features were obtained, and whole-exome sequencing was conducted on a patient with LTBL.

The beneficial effects of D-allose and D-allulose on the brain under ischemic stroke and obese-insulin resistant conditions: evidence from in vitro to clinical studies.

Ischemic stroke, and obese-insulin resistance are common pathological conditions that lead to brain injury, resulting in neurodegeneration, brain atrophy, and cognitive dysfunction. Rare sugars, which are scarce monosaccharide in nature, have been investigated as a potential treatment for these adverse conditions. However, the beneficial effects of rare sugars on the brain have never been summarized.

Application of Machine Learning for Patients With Cardiac Arrest: Systematic Review and Meta-Analysis.

Background: Currently, there is a lack of effective early assessment tools for predicting the onset and development of cardiac arrest (CA). With the increasing attention of clinical researchers on machine learning (ML), some researchers have developed ML models for predicting the occurrence and prognosis of CA, with certain models appearing to outperform traditional scoring tools. However, these models still lack systematic evidence to substantiate their efficacy.

Electrocatalytic Acetylene Semi-Hydrogenation to Ethylene with High Energy Efficiency.

Electrocatalytic acetylene semi-hydrogenation (EASH) provides a petroleum-independent strategy for ethylene production. However, the challenges of high overpotentials and strong hydrogen evolution competition reaction over conventional electrocatalysts at industrial current densities result in substantial energy consumption, limiting the practical application of EASH technology. Herein, zinc-doped copper catalysts are designed and prepared via a facile impregnation and electroreduction relay method.

DOCK8 gene mutation alters cell subsets, BCR signaling, and cell metabolism in B cells.

DOCK8 deficiency has been shown to affect the migration, function, and survival of immune cells in innate and adaptive immune responses. The immunological mechanisms underlying autosomal recessive (AR) hyper-IgE syndrome (AR-HIES) caused by DOCK8 mutations remain unclear, leading to a lack of specific therapeutic options. In this study, we used CRISPR/Cas9 technology to develop a mouse model with a specific DOCK8 point mutation in exon 45 (c.

Ocotillol Derivatives Mitigate Retinal Ischemia-Reperfusion Injury by Regulating the Keap1/Nrf2/ARE Signaling Pathway.

Retinal ischemia-reperfusion (RIR) injury can lead to various retinal diseases. Oxidative stress is considered an important pathological event in RIR injury. Here, we designed and synthesized 34 ocotillol derivatives, then examined their antioxidant and anti-inflammatory capacities; we found that compounds (C24-) and (C24-) were most active.

Effectiveness of acupuncture on urinary retention after radical hysterectomy for cervical cancer in China: a systematic review and meta-analysis.

Background: Cervical cancer is one of the most common malignant tumors worldwide. Radical hysterectomy is the first choice for patients with early-stage cervical cancer. Studies have suggested that acupuncture may be a more effective therapy for the prevention and treatment of urinary retention after radical hysterectomy.

METTL14/YTHDC1-Mediated m6A Modification in Hippocampus Improves Pentylenetetrazol-Induced Acute Seizures.

Epilepsy is a common neurological disorder which can cause significant morbidity and mortality. N6-methyladenosine (m6A), the most common chemical epigenetic modification among mRNA post-transcriptional modifications, implicated in various physiological and pathological processes, but its role in epilepsy is still unknown. Here, we provide strong evidences in support of an association of m6A and its regulatory proteins with epilepsy.

High yield electrosynthesis of oxygenates from CO using a relay Cu-Ag co-catalyst system.

As a sustainable alternative to fossil fuel-based manufacture of bulk oxygenates, electrochemical synthesis using CO and HO as raw materials at ambient conditions offers immense appeal. However, the upscaling of the electrosynthesis of oxygenates encounters kinetic bottlenecks arising from the competing hydrogen evolution reaction with the selective production of ethylene. Herein, a catalytic relay system that can perform in tandem CO capture, activation, intermediate transfer and enrichment on a Cu-Ag composite catalyst is used for attaining high yield CO-to-oxygenates electrosynthesis at high current densities.

Measurement of ctDNA Tumor Fraction Identifies Informative Negative Liquid Biopsy Results and Informs Value of Tissue Confirmation.

Purpose: Liquid biopsy (LBx) for tumor profiling is increasingly used, but concerns remain regarding negative results. A lack of results may truly reflect tumor genomics, or it may be a false negative that would be clarified by tissue testing. A method of distinguishing between these scenarios could help clarify when follow-on tissue testing is valuable.

Plasminogen activator inhibitor 1 is associated with high-grade serous ovarian cancer metastasis and is reduced in patients who have received neoadjuvant chemotherapy.

High-grade serous ovarian cancer (HGSOC) is the most prevalent and deadliest subtype of epithelial ovarian cancer (EOC), killing over 140,000 people annually. Morbidity and mortality are compounded by a lack of screening methods, and recurrence is common. Plasminogen-activator-inhibitor 1 (PAI-1, the protein product of SERPIN E1) is involved in hemostasis, extracellular matrix (ECM) remodeling, and tumor cell migration and invasion.

Breviscapine attenuates lead‑induced myocardial injury by activating the Nrf2 signaling pathway.

The present study investigated the therapeutic potential of breviscapine (Bre) in mitigating lead (Pb)-induced myocardial injury through activation of the nuclear factor erythroid-2 related factor 2 (Nrf2) pathway. Rat cardiomyocytes (H9C2 cells) were exposed to Pb to model Pb poisoning, and various parameters, including cell viability, apoptosis and reactive oxygen species (ROS) production, were assessed using Cell Counting Kit-8, flow cytometry and 2',7'-dichlorfluoresceindiacetate assays, respectively. Additionally, a rat model of Pb poisoning was established in which blood Pb levels were measured using a graphite furnace atomic absorption spectrophotometer, and alterations in myocardial tissue, oxidative stress markers, inflammatory indicators, protein expression related to apoptosis and the Nrf2 pathway were evaluated via histopathology, ELISA and western blotting.
