Tantalum disulfide (1T-TaS), being a Mott insulator with strong electron correlation, is highlighted for diverse collective quantum states in the 2D lattice, including charge density wave (CDW), spin liquid, and unconventional superconductivity. The Mott physics embedded in the 2D triangular CDW lattice has raised debates on stacking-dependent properties because interlayer interactions are sensitive to van der Waals (vdW) spacing. However, control of interlayer distance remains a challenge.

SLE affects females rather than males with a ratio of about 9:1. Owing to the high morbidity with multiple organ involvement, SLE flare-up remains a challenge for women's health. In an accumulation of the past 70 years of studies globally, EBV has been found to be strongly associated with SLE.

Connective tissue disease-associated interstitial lung disease (CTD-ILD) is a severe manifestation of CTD that leads to significant morbidity and mortality. Clinically, ILD can occur in diverse CTDs. Pathologically, CTD-ILD is characterized by various histologic patterns, such as nonspecific interstitial pneumonia, organizing pneumonia, and usual interstitial pneumonia.

Aim: To analyze the clinical patterns of new-onset inflammatory arthritis after COVID-19 vaccination among patients without pre-existing rheumatic or autoimmune diseases.

Method: Case reports and series of new-onset inflammatory arthritis after COVID-19 vaccination were collected before April 2022. Clinical characteristics including diagnosis, age, gender, vaccine types, time interval between events, joint involvement (poly- or oligo-/monoarthritis), and laboratory data reflecting inflammatory status were sorted and P values between these parameters are calculated with independent sample Student's t test or 2 × 2 Fisher's exact test.

To demonstrate the loci that relate to high-density lipoprotein cholesterol (HDL-C) levels and genetic sex heterogeneity, we enrolled 41,526 participants aged between 30 and 70 years old from the Taiwan Biobank in a genome-wide association study. We applied the Manhattan plot to display the p-values estimated for the relationships between loci and low HDL-C. A total of 160 variants were significantly associated with low HDL-C.

() is an edible profitable herb with high phenolic content that recognized herb relieves skin disorder, antityrosinase, and anticancer. Along with these health benefits , however, there is no study on the factors that influence the phenolic content of extraction by water-based ultrasonic-microwave-assisted extraction (UMAE). The aim of this study evaluates UMAE conditions (ultrasonic power, microwave power, and extraction time) on responses using response surface Box-Behnken design and compared with the hydrothermal extraction.

Harmonizing formulas are associated with beneficial renal outcomes in chronic kidney disease (CKD), but the therapeutic mechanisms are unclear. The study aims to explore the associations of intentions and independent factors with harmonizing formulas prescriptions for patients with CKD. We conducted a population-based cross-sectional study to explore factors associated with harmonizing formulas prescription.

Variants of transcription factor binding sites (TFBSs) constitute an important part of the human genome. Current evidence demonstrates close links between nucleotides within TFBSs and gene expression. There are multiple pathways through which genomic sequences located in TFBSs regulate gene expression, and recent genome-wide association studies have shown the biological significance of TFBS variation in human phenotypes.

In this study, we examined data from 69 gout patients and 1,455 non-gout controls using a MethylationEPIC BeadChip assay and Illumina HiSeq platform to identify lineage-specific epigenetic alterations and associated genetic factors that contributed to gouty inflammation. Cell lineage-specific differentially methylated sites were identified using CellDMC after adjusting for sex, age, alcohol drinking, smoking status, and smoking history (total pack-years). Different cell lineages displayed distinct differential methylation.

Current knowledge of gout centers on hyperuricemia. Relatively little is known regarding the pathogenesis of gouty inflammation. To investigate the epigenetic background of gouty inflammation independent of hyperuricemia and its relationship to genetics, 69 gout patients and 1455 non-gout controls were included.

Objective: Recent studies have reported that reduced excretion of urinary uromodulin is associated with renal tubular function and risks of progressive kidney disease. Gouty nephropathy is usually seen in patients with gout. Patients with chronic gouty nephropathy are characterized by the deposition of monosodium urate crystals primarily involving the collecting ducts in the medulla.

Aim: We aimed to assess the receipt of recommended care for young children with sickle cell disease (SCD) in a central SCD clinic in Kampala Uganda, focusing on standard vaccination and antibacterial and antimalarial prophylaxis.

Methods: A cross-sectional assessment of immunisation status and timeliness and prescribed antibacterial and antimalarial prophylaxis was performed in a sample with SCD aged ≤71 months in Mulago Hospital SCD Clinic. Government-issued immunisation cards and clinic-issued visit records for prescribed prophylaxis were reviewed.

Background: Accumulating evidence implicates mitochondrial DNA (mtDNA) alleles, which are independent of the nuclear genome, in disease, especially in human metabolic diseases. However, this area of investigation has lagged behind in researching the nuclear alleles in complex traits, for example, in gout.

Methods: Next-generation sequencing was utilized to investigate the relationship between mtDNA alleles and phenotypic variations in 52 male patients with gout and 104 age-matched male non-gout controls from the Taiwan Biobank whole-genome sequencing samples.

Although many genome-wide association studies (GWASs) of hyperuricemia or gout have been reported, the related genetic factors and the mechanisms from hyperuricemia to gouty attack remain unclear. This study aimed to identify genetic factors and pathogenesis of gout from hyperuricemia by genome-wide association study (GWAS). 747 gout patients, 747 hyperuricemia and 2071 age-matched controls were recruited and analyzed with Affymetrix 650 K chip to find the related genetic variants.

Background: The pandemic influenza A (H1N1) virus has spread worldwide and infected a large proportion of the human population. Discovery of new and effective drugs for the treatment of influenza is a crucial issue for the global medical community. According to our previous study, TSL-1, a fraction of the aqueous extract from the tender leaf of Toonasinensis, has demonstrated antiviral activities against pandemic influenza A (H1N1) through the down-regulation of adhesion molecules and chemokine to prevent viral attachment.

Article Synopsis
  • Rikkunshito, a traditional Chinese medicine, shows potential in improving anorexia for cancer patients and reducing lung injury by limiting neutrophil infiltration.
  • In a study involving 17 advanced non-small cell lung cancer (NSCLC) patients, the effects of rikkunshito combined with standard chemotherapy were analyzed, focusing on treatment response and gene expression changes.
  • Results indicated no significant differences in overall survival or clinical outcomes between the groups; however, rikkunshito treatment led to notable changes in certain blood cell counts and gene expression linked to immune response and inflammation.

Article Synopsis
  • The study investigates the impact of chronic intermittent hypoxia and re-oxygenation on patients with obstructive sleep apnea (OSA) by analyzing gene expression in peripheral blood cells from 48 patients.
  • Researchers found eight genes that changed expression levels with OSA severity and continuous positive airway pressure (CPAP) treatment, highlighting specific proteins associated with conditions like hypertension and chronic kidney disease.
  • The findings suggest that certain genes (AMOT, PLEKHH3, BIRC3, ADAR1, LGALS3) are linked to severe OSA and its complications, indicating potential targets for understanding and treating associated health issues like hypersomnia and hypertension.
