Bioinformatics analysis identifies WNK1 gene as a potential biomarker for cholangiocarcinoma diagnosis and immune infiltration.

Background: Cholangiocarcinoma (CHOL) is a malignant epithelial carcinoma of the digestive system with poor prognosis and high mortality. WNK lysine deficient protein kinase 1 (WNK1) is known to be associated with tumorigenesis in various cancers. However, the relationship between WNK1 and CHOL development, as well as the potential mechanisms involved, remains poorly understood.

Methods: The pain-associated gene sphingosine-1-phosphate receptor 1 (S1PR1) was identified in ASD samples through bioinformatics analysis.

Chromosomal analysis in pregnant women of advanced maternal age: indications for prenatal diagnosis.

The demographic of women of advanced maternal age (AMA), defined as those over 35 years, is expanding in response to the liberalization of China's three-child policy. A significant proportion of these women are electing to undergo noninvasive prenatal testing (NIPT). Nonetheless, next-generation sequencing (NGS) is the recommended method for prenatal screening among women of AMA in the world.

LncRNA-Mediated TPI1 and PKM2 Promote Self-Renewal and Chemoresistance in GBM.

Temozolomide (TMZ) resistance is one of the major reasons for poor prognosis in patients with glioblastoma (GBM). Long noncoding RNAs (lncRNAs) are involved in multiple biological processes, including TMZ resistance. Linc00942 is a potential regulator of TMZ sensitivity in GBM cells is shown previously.

Deletion of ASPP1 in myofibroblasts alleviates myocardial fibrosis by reducing p53 degradation.

In the healing process of myocardial infarction, cardiac fibroblasts are activated to produce collagen, leading to adverse remodeling and heart failure. Our previous study showed that ASPP1 promotes cardiomyocyte apoptosis by enhancing the nuclear trafficking of p53. We thus explored the influence of ASPP1 on myocardial fibrosis and the underlying mechanisms.

Integrated analysis of N6-methyladenosine- and 5-methylcytosine-related long non-coding RNAs for predicting prognosis in cervical cancer.

Background: N6-methyladenosine (mA) and 5-methylcytosine (mC) play a role in modifying long non-coding RNAs (lncRNAs) implicated in tumorigenesis and progression. This study was performed to evaluate prognostic value of mA- and mC-related lncRNAs and develop an efficient model for prognosis prediction in cervical cancer (CC).

Methods: Using gene expression data of TCGA set, we identified mA- and mC-related lncRNAs.

Correlation of Co-Morbidities with Symptom Severity of Children with Autism Spectrum Disorder: A Cross-Sectional Survey.

This study aims to identify potential correlations of the severity of symptoms of children with autism spectrum disorder (ASD) with serum nutritional levels, body composition indicators, diet partiality, and sleep disturbances. The cohort of this cross-sectional study included 120 children with ASD and 110 typically developing (TD) children to assess symptoms of ASD, and to measure serum levels of vitamins and minerals and the body composition values. Diet partiality and sleep disturbances were assessed by administering questionnaires.

Identification and Validation of Cytotoxicity-Related Features to Predict Prognostic and Immunotherapy Response in Patients with Clear Cell Renal Cell Carcinoma.

Background: Clear cell renal cell carcinoma (ccRCC) is a renal cortical malignancy with a complex pathogenesis. Identifying ideal biomarkers to establish more accurate promising prognostic models is crucial for the survival of kidney cancer patients.

Methods: Seurat R package was used for single-cell RNA-sequencing (scRNA-seq) data filtering, dimensionality reduction, clustering, and differentially expressed genes analysis.

Polymer-locking fusogenic liposomes for glioblastoma-targeted siRNA delivery and CRISPR-Cas gene editing.

In patients with glioblastoma (GBM), upregulated midkine (MDK) limits the survival benefits conferred by temozolomide (TMZ). RNA interference (RNAi) and CRISPR-Cas9 gene editing technology are attractive approaches for regulating MDK expression. However, delivering these biologics to GBM tissue is challenging.

Association between intake of flavanones and the overweight/obesity and central obesity in children and adolescents: a cross-sectional study from the NHANES database.

Aim: The prevalence of obesity (Ob), overweight (Ow) and central obesity (CO) in children and adolescents has increased dramatically over the past decades globally. Flavanones have been recently studied as adjuvants for the treatment of obesity. This study was aimed at evaluating the association between intake of flavanones and its subclasses and the Ow/Ob and CO in children and adolescents.

Rat gingival fibroblasts were divided into five groups: (1) control, (2) LPS treatment, (3) laser treatment, (4) TB treatment (1.0 µg/mL), and (5) PDT treatment (TB plus laser irradiation at 320 mW/cm for 240 s).

In vivo detection of the epimer metabolites of sweroside via ultra-performance liquid chromatography time-of-flight mass spectrometry combined with DNPH derivatization.

The metabolites of sweroside were first investigated in vivo with ultra-performance liquid chromatography time-of-flight mass spectrometry (UPLC-TOF-MS) in combination with 2,4-dinitrophenylhydrazine derivatization. In addition, the mass detection sensitivity of the major metabolites, epinaucledal and naucledal, via UPLC-TOF-MS was significantly enhanced, and the epimer metabolites were distinctly discovered from plasma following gavage of sweroside in rats. The plasma concentration of epinaucledal and naucledal was quantified via UPLC-TOF-MS in negative mode using erythrocentaurin as the internal standard.
