Targeting Metabolic and Epigenetic Vulnerabilities in Glioblastoma with SN-38 and Rabusertib Combination Therapy.

Glioblastoma (GBM), the most prevalent primary malignant brain tumor, remains challenging to treat due to extensive inter- and intra-tumor heterogeneity. This variability demands combination treatments to improve therapeutic outcomes. A significant obstacle in treating GBM is the expression of O-methylguanine-DNA methyltransferase, a DNA repair enzyme that reduces the efficacy of the standard alkylating agent, temozolomide, in about 50% of patients.

Rapid Antibacterial Assessments for Plastic and Textile Materials Against .

: Standard test methods for evaluating the antibacterial performance of plastic (non-porous) and textile (porous) materials are accurate and reliable, but completing a standard assessment generally requires at least several days to a week. Well-trained and experienced technicians are also required to conduct the standard tests consistently and analyse the samples and test results systemically. These costs are often not favourable for the performance assurance of antimicrobial products in industrial production, nor for meeting the fast-return demands in research and development of antimicrobial materials nowadays.

Interocular retinal asymmetry and cognitive frailty: A prospective cohort study.

Introduction: The retinal nerve fiber layer (RNFL) or ganglion cell-inner plexiform layer (GC-IPL) is associated with cognitive impairment. However, the relationship between retinal asymmetry and cognitive frailty (CF) remains unknown.

Methods: Two hundred twenty-two community-dwelling older adults were assessed starting in 2015 and underwent biennial cognitive and frailty evaluations until 2022.

Multi-omics analysis reveals alterations of breastmilk metabolites and proteins in Hong Kong lactating mothers.

The nutritional contents of breastmilk (BM) directly participate in neonatal metabolism via breastfeeding. Currently, there is limited research on BM metabolites and proteins compositions, and their alterations during the long lactation period in Hong Kong mothers. In this study, liquid chromatography-mass spectrometry-based metabolomics, lipidomics and proteomics studies were applied to compare the compositions in BM of Hong Kong lactating mothers at the 2nd, 6th, and 12th months after delivery.
