Application analysis of two nucleic acid detection systems in blood detection of hepatitis B virus, hepatitis C virus and human immunodeficiency virus

"This study provides the first large-scale comparison of Kehua and Roche NAT systems for HBV, HCV, and HIV screening in blood donations. Analyzing over 670,000 samples, it shows Kehua performs comparably to Roche but with fewer invalid tests and lower operational costs, supporting its use as a reliable, cost-effective alternative."

Machine learning classification of mango maturity based on carotene content from Raman spectra

"This article makes a meaningful step forward in non-invasive fruit quality assessment by integrating Raman spectroscopy with machine learning for mango maturity classification. This contributes new knowledge about carotenoid spectral fingerprints as reliable markers of ripening and positions Raman spectroscopy as a superior alternative to color-based or NIR methods."

Tryptophan-kynurenine pathway: a possible new mechanism for the prevention and treatment of reproductive system-related diseases

"This work highlights the significance of the tryptophan–kynurenine metabolic pathway as an overlooked but potentially crucial mechanism in reproductive health. By linking abnormalities in this pathway’s enzymes and metabolites to reproductive disorders, it suggests new therapeutic strategies—such as targeting pathway inhibitors or modulating gut tryptophan metabolism, presenting an interesting perspective and offering novel targets for preventing and treating reproductive diseases."

Assessment of distinct effects of Parinari curatellifolia Planch.ex Benth Ethanolic leaf extract on glucose transport in different cell types

"Parinari curatellifolia leaf extract (PCE) shows antidiabetic potential, inhibiting glucose transport in adipocytes (50% at 100 µg/mL) while doubling it in Caco-2 intestinal cells via increased GLUT1. Effects vary by cell type, suggesting further in vivo studies at low doses."

NAT10 inhibits ferroptosis and promotes the progression of renal clear cell carcinoma by regulating the NFE2L1-GPX4 signaling pathway

"The research demonstrates that NAT10 enhances the malignant behavior of ccRCC cells, suggesting its involvement in tumor progression. The study identifies that NAT10 inhibits ferroptosis by modulating the NFE2L1-GPX4 signaling pathway, a novel finding in the context of ccRCC. Given its regulatory role in ferroptosis and tumor progression, NAT10 presents as a promising target for ccRCC treatment options. So, this study contributes to the understanding of ccRCC pathogenesis and opens avenues for targeted therapies that modulate ferroptosis pathways, of which, thus far, there is limited direct evidence in literature."

Antimicrobial and scavenging potential of green synthesized silver/manganese bimetallic nanoparticles using Euphorbia cactus extract

"This work is a strong, novel, and thoughtfully executed step in the direction of sustainable nanomedicine. The use of Euphorbia-based bio-reduction to generate Ag/Mn bimetallic nanoparticles, characterised in detail and shown to possess potent antimicrobial and antioxidant function, is valuable. The main outstanding challenges are proof of biocompatibility, mechanistic clarity, reproducibility, and translation feasibility. Translational impact remains preliminary."

Modulation of PI3K/AKT/mTOR and apoptosis pathway in colon cancer cells by the plant flavonoid fisetin

"This research elucidates how fisetin affects key molecular pathways in CRC cells. By downregulating BCL-2, PI3K, mTOR, and NF-κB gene expression, and upregulating BAX gene expression, fisetin disrupts the PI3K/AKT/mTOR pathway and promotes apoptosis. Utilizing the Caco-2 human colon cancer cell line, the study provides a relevant in vitro model to assess fisetin's effects. Supporting analyses using GeneMANIA and OncoDB databases reinforce the observed gene expression changes, lending credibility to the findings. This study contributes to the growing body of evidence supporting fisetin as a promising natural compound for CRC prevention and therapy, making it an interesting therapeutic candidate for future formulations."

Quality assessment from biobank plasma and serum specimens: a systematic review

"Unreliable blood sample quality can distort research findings, waste resources, and compromise clinical decisions. By identifying the key factors that damage samples and highlighting overlooked variables, this work helps to establish a foundation for standardized handling that preserves integrity, improves reproducibility, and strengthens trust in biobank-based studies."
