Population pharmacokinetics of levofloxacin in breastmilk in patients with rifampicin‐resistant tuberculosis

British Journal of Clinical Pharmacology, EarlyView.
Levofloxacin is a widely used antibiotic included in rifampicin‐resistant tuberculosis (RR‐TB) treatment. Data describing levofloxacin concentrations in breastmilk and infant exposure are limited. We analysed data from two South African studies of breastfeeding women receiving levofloxacin (750–1000 mg daily) for RR‐TB.

Magnetoelastic Cell Monitoring System for Evaluating the Effects of Surface Chemistry on the Performance of Mesenchymal Stem Cell Growth

Biotechnology and Bioengineering, EarlyView.
ABSTRACT The recent clinical adoption of cell therapies has increased the need for more efficient, robust, and reproducible manufacturing technologies. Human mesenchymal stromal cells (hMSCs), a major component of the cell and immunotherapeutic market, remain challenging to manufacture at scale because they require surface attachment and are highly ...

Purification of Disassembled Capsid Protein by Hydroxyapatite Chromatography Enhances Virus‐Like Particle Recovery

Biotechnology and Bioengineering, EarlyView.
ABSTRACT Virus‐like particles (VLPs) are a promising modality with extensive applications in prophylactic and therapeutic vaccine design. Human Papillomavirus (HPV) vaccines are one such example where VLP vaccine applications have led to the successful reduction in HPV‐associated diseases, such as cervical cancer.

From apex to base: Uncovering spatial metabolic adaptation in Antarctic mosses

Bulletin of the Korean Chemical Society, EarlyView.
Antarctic mosses survive extreme cold, desiccation, UV exposure, and oxidative stress. We analyzed three species by separating apical, middle, and basal zones. Each zone showed distinct metabolite patterns and biological roles, revealing spatial metabolic specialization. The results suggest that whole‐plant survival depends on coordinated contributions

Multimodal Fluorescent MOF@BODIPY Platform: Bridging Sensing and Mechanistic Insight

Chemistry – A European Journal, EarlyView.
ABSTRACT Hybrid metal–organic frameworks (MOFs) that integrate organic chromophores constitute powerful platforms for optical sensing by combining structural order with tunable photophysics. Incorporating photoresponsive chromophores into MOFs enables sensitive probing of guest–framework interactions through well‐defined luminescent signatures. Herein,
