Background: Herpes simplex keratitis (HSK) is a recurrent inflammatory disease of cornea primarily initiated by type I herpes simplex virus infection of corneal epithelium. However, early diagnosis of HSK remains challenging due to the lack of specific biomarkers. This study aims to identify biomarkers for HSK through tear metabolomics analysis between HSK and healthy individuals.

Establishment and validation of HPLC methods for the determination of folic acid and parabens antimicrobial agents on folic acid oral solution.

Background: As the common antibacterial drugs in folic acid oral liquid, parabens are listed as mandatory substances in the quality standard. Both the Chinese Pharmacopoeia and the United States Pharmacopoeia use high performance liquid chromatography for the determination of folic acid, but the quantitative methods of parabens are different. Pharmacopoeias use different instruments to quantify folic acid and parabens, resulting in cumbersome and cumbersome detection methods.

Structural insights into RNA cleavage by PIWI Argonaute.

Argonaute proteins are categorized into AGO and PIWI clades. Across most animal species, AGO-clade proteins are widely expressed in various cell types, and regulate normal gene expression. By contrast, PIWI-clade proteins predominantly function during gametogenesis to suppress transposons and ensure fertility.

The role of preoperative serum thyroglobulin in the diagnosis and treatment of differentiated thyroid cancer: a systematic review and meta-analysis.

Background: Serum thyroglobulin (Tg) is a critical marker for monitoring tumor recurrence and metastasis in patients who have undergone total thyroidectomy for differentiated thyroid cancer (DTC). While the definitive role of preoperative serum Tg in DTC is not yet established, studies suggest its importance in differentiating between benign and malignant thyroid nodules with indeterminate cytology, as well as in predicting distant metastasis (DM) in patients with DTC.

Methods: A thorough literature review was conducted on the use of preoperative serum Tg in differentiating between benign and malignant thyroid nodules, and in evaluating the extent of DTC lesions.

Annexin A5 knockdown inhibits cardiomyocyte apoptosis and alleviates cardiac hypertrophy via activating the PI3K/AKT/Bcl-2 signaling pathway.

Annexin A5 (ANXA5) is a small calcium-dependent protein that binds specifically to negatively charged phosphatidylserine as a marker of apoptosis. Previous studies have shown that ANXA5 expression is elevated in hypertensive patients and is closely related to left ventricular systolic function in hypertensive patients, but its specific mechanism of action has not been clarified. GEO database analysis showed that ANXA5 expression was significantly upregulated in hypertensive myocardial hypertrophy.

ATF5-mediated mitochondrial unfolded protein response protects against Pb-induced mitochondria damage in SH-SY5Y cell.

Mitochondria is the primary target of lead (Pb) in neural cells, and Pb exposure can cause impairment to mitochondrial function and morphology. Recent studies have reported that a conserved cellular stress response, called mitochondrial unfolded protein response (mtUPR), is activated in response to mitochondrial dysfunction and protein misfolding and play protective roles in aging and neurodegeneration, but it's unknown whether mtUPR could protect against Pb-induced neurotoxicity. In this study, we found that sublethal level exposure of PbAc (2.

It is well established that humoral immunity targeting hepatitis B virus surface antigen (HBsAg) plays a critical role in viral clearance and clinical cure. However, the functional changes in HBsAg-specific B cells before and after achieving functional cure remain poorly understood. In this study, we characterized circulating HBsAg-specific B cells and identified functional shifts and B-cell epitopes directly associated with HBsAg loss.

EMBRYONIC FLOWER 1 regulates male reproduction by repressing the jasmonate pathway downstream transcription factor MYB26.

The evolutionarily conserved Polycomb repressive complexes (PRCs) mediate genome-wide transcriptional silencing and regulate a plethora of development, as well as environmental responses in multicellular organisms. The PRC2-catalyzed trimethylation of lysine 27 on histone H3 (H3K27me3) is recognized by reader-effector modules of Polycomb repressive complex 1 (PRC1) to implement gene repression. Here, we report that the Arabidopsis (Arabidopsis thaliana) H3K27me3 effector EMBRYONIC FLOWER 1 (EMF1) interacts with and constrains the R2R3 DNA binding transcription factor MYB26 by a eudicot-conserved motif in the stamen.
