Performance Evaluation of the VISITECT CD4 Lateral Flow Point‐Of‐Care Assay for Identifying Advanced HIV Disease

Journal of Clinical Laboratory Analysis, EarlyView.
The VISITECT CD4 lateral flow assay (LFA) was evaluated for identifying advanced HIV disease (CD4 ≤ 200 cells/μL) during routine programmatic implementation in Argentina. The assay showed 100% sensitivity, while specificity improved after observer training, reflecting reduced reader‐dependent variability.

Production of recombinant human granulocyte‐macrophage colony‐stimulating factor in thermoinducible E. coli: Tuning inclusion body architecture and protein yield via dissolved oxygen control

Journal of Chemical Technology &Biotechnology, EarlyView.
Abstract BACKGROUND Recombinant protein expression in Escherichia coli frequently results in the formation of inclusion bodies (IBs), which provide high protein accumulation but often require additional steps to recover functional protein. Although culture conditions strongly influence IB physicochemical and structural characteristics, the impact of ...

Low‐Intensity Precipitation Dominates Peninsular Spain (1961–2022)

International Journal of Climatology, EarlyView.
Spatial analysis across Spain shows a shift in precipitation regimes (1961–2022) toward more frequent low‐intensity precipitation and reduced high‐intensity events, with localised increases in heavy precipitation along some coastal areas. This redistribution—captured through changes in precipitation frequency (RF) and volumetric contribution (RC ...
