Progress in research on osteoporosis secondary to SARS-CoV-2 infection.

The World Health Organization has declared that COVID-19 no longer constitutes a "public health emergency of international concern," yet the long-term impact of SARS-CoV-2 infection on bone health continues to pose new challenges for global public health. In recent years, numerous animal model and clinical studies have revealed that severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection can lead to secondary osteoporosis. The mechanisms involved are related to the virus's direct effects on bone tissue, dysregulation of the body's inflammatory response, hypoxia, noncoding RNA imbalance, and metabolic abnormalities.

ILC3 Function as a Double-Edged Sword in EV71 Infection.

Enterovirus 71 (EV71) is a common pathogen responsible for hand, foot, and mouth disease (HFMD), leading to severe neurological complications and even death. However, the mechanisms underlying severe EV71-induced disease remain unclear, and no effective specific treatments are available. In this study, we successfully infected mice of different ages using a mouse-adapted EV71 strain, resulting in disease and mortality.

Determination of arsenic speciation of arsenic in squid and its human consumption risk.

Arsenic species were quantified to further explore the biotransformation of arsenic and better explain the potential health risks. In this research, the levels of six arsenic species (AsB, AsC, MMA, DMA, As, and As) were determined in 160 squid samples by HPLC-ICP-MS. AsB was the most predominant speciation in squid tissues.

Lactate-to-albumin ratio as a potential prognostic predictor in patients with cirrhosis and sepsis: a retrospective cohort study.

Background: Patients with liver cirrhosis face high infection risks due to immune dysfunction and hospital-related factors, increasing mortality rates when sepsis occurs. While various biomarkers predict outcomes in cirrhosis, few are accessible and reliable. This study addresses the gap by evaluating the prognostic potential of the lactate-to-albumin ratio (LAR).

Exploring the co-morbid relationship between Alzheimer's disease and lung cancer in the 5xFAD transgenic mouse model.

Background: Alzheimer's disease (AD) and lung cancer are leading causes of mortality among the older population. Epidemiological evidence suggests an antagonistic relationship between them, whereby patients with AD exhibit a reduced risk of developing cancer and vice versa. However, the precise mechanism by which AD antagonizes lung cancer progression warrants further elucidation.

TWIST1 regulates HK2 ubiquitination degradation to promote pancreatic cancer invasion and metastasis.

Objective: TWIST1 is known to promote glycolysis and contribute to pancreatic cancer development; however, its underlying mechanisms remain poorly understood. This study aims to elucidate the molecular mechanisms by which TWIST1 influences aerobic glycolysis in pancreatic ductal adenocarcinoma (PDAC).

Methods: The expression levels of TWIST1, MMP9, MT1-MMP, and FDX1 in clinical tissues and cancer cell lines were assessed using quantitative reverse transcription PCR (QRT-PCR).

End-stage liver diseases, such as hepatocellular carcinoma or acute liver failure, critically necessitate liver transplantation. However, the shortage of available organ donors fails to meet the rapidly growing transplantation demand. Due to the high similarity of liver tissue structure and metabolism between miniature pigs and humans, xenotransplantation of pig livers is considered as a potentially viable solution to organ scarcity.

Circulating insulin-like growth factor-1 and the risk of multiple sclerosis: a prospective cohort study.

Background: Circulating insulin-like growth factor 1 (IGF-1) is positively associated with the risks of certain neurological disorders, including stroke, Alzheimer's disease, and Parkinson's disease. However, the association of IGF-1 with the risk of multiple sclerosis (MS) remains unclear.

Methods: A total of 348,324 participants at baseline were included from the UK biobank in this prospective study.

scHNTL: single-cell RNA-seq data clustering augmented by high-order neighbors and triplet loss.

Motivation: The rapid development of single-cell RNA sequencing (scRNA-seq) has significantly advanced biomedical research. Clustering analysis, crucial for scRNA-seq data, faces challenges including data sparsity, high dimensionality, and variable gene expressions. Better low-dimensional embeddings for these complex data should maintain intrinsic information while making similar data close and dissimilar data distant.

Bone marrow mesenchymal stem cells derived cytokines associated with AKT/IAPs signaling ameliorate Alzheimer's disease development.

Background: Alzheimer's disease (AD) is a progressive neurodegenerative condition affecting around 50 million people worldwide. Bone marrow-derived mesenchymal stem cells (BMMSCs) have emerged as a promising source for cellular therapy due to their ability to differentiate into multiple cell types and their paracrine effects. However, the direct injection of BMMSCs can lead to potential unpredictable impairments, prompting a renewed interest in their paracrine effects for AD treatment.

Can ACR TI-RADS predict the malignant risk of medullary thyroid cancer?

Objectives: This study aimed to evaluate the diagnostic performance for medullary thyroid cancer (MTC) based on the 2017 Thyroid Imaging Reporting and Data System by the American College of Radiology (ACR TI-RADS) guideline, and the ability to recommend fine needle aspiration (FNA) for MTC.

Methods: Fifty-six MTCs were included, and 168 benign thyroid nodules (BTNs) and 168 papillary thyroid nodules (PTCs) were matched according to age. Ultrasound (US) features were reviewed according to ACR TI-RADS.

A broadly neutralizing antibody against the SARS-CoV-2 Omicron sub-variants BA.1, BA.2, BA.2.12.1, BA.4, and BA.5.

The global spread of Severe Acute Respiratory Syndrome Coronavirus 2. (SARS-CoV-2) and its variant strains, including Alpha, Beta, Gamma, Delta, and now Omicron, pose a significant challenge. With the constant evolution of the virus, Omicron and its subtypes BA.

Prognostic significance of albumin corrected anion gap in patients with acute pancreatitis: a novel perspective.

This study aims to explore the relationship between the albumin-corrected anion gap (ACAG) and short- and long-term all-cause mortality (ACM) in patients with acute pancreatitis (AP) managed in the intensive care unit (ICU).

Background: Oxidative stress and microglial activation are critical pathomechanisms in ischemic white matter injury. Microglia, as resident immune cells in the brain, are the main cells undergoing oxidative stress response. However, the role and molecular mechanism of oxidative stress in microglia have not been clearly elucidated during white matter ischemia.

Association of neutrophil percentage to albumin ratio with gallstones: a cross-sectional study from the United States NHANES.

Background And Objective: The neutrophil percentage to albumin ratio (NPAR) is an emerging, costimulatory indicator of inflammation that is associated with a variety of diseases, such as non-alcoholic fatty liver disease, liver fibrosis, stroke, and cardiovascular disease. However, the relationship between NPAR and gallstones (GS) has not yet been explored. Therefore, this study aimed to evaluate the association of the NPAR with the odds of GS and the age of patients at the time of their first GS surgery.

Arsenic exposure accelerates type 1 diabetes mellitus progression via pyroptosis pathway in mice.

The relationship between arsenic exposure and the development of diabetes mellitus has garnered significant interest in recent years. However, current experimental studies have not definitively established the role of arsenic in the onset of diabetes mellitus. To investigate this relationship specifically concerning type 1 diabetes mellitus, Streptozocin (STZ) was utilized as an inducer to initiate the fundamental pathological changes associated with the disease.
