Assessment of Indoor Air Quality for Group-Housed Macaques (Macaca spp.)

Animals, 2022
Indoor Air Quality (IAQ) is strongly associated with animal health and wellbeing. To identify possible problems of the indoor environment of macaques (Macaca spp.), we assessed the IAQ.

MARK4 enhances stress granule formation under oxidative stress and increases tau accumulation

FEBS Open Bio, EarlyView.
MARK4 (red dots) localizes to stress granules (orange dots) and promotes their formation under oxidative stress by modulating TIA1 (blue dots). MARK4 and TIA1 synergistically increase tau (purple) accumulation, and the reduction of the TIA1 ortholog suppresses neurodegeneration in a fly model.

Enhanced Ventilation and Energy Efficiency of an Optimized Double-Channel Solar Chimney

Buildings
This study explores the use of solar chimneys to harness solar radiation, generating a chimney effect that promotes natural ventilation in buildings. However, the performance of double-channel solar chimneys is heavily influenced by their installation ...

IGF2 knockout reduces but does not abolish osteosarcoma growth in vitro and in vivo

FEBS Open Bio, EarlyView.
To test whether endogenous IGF2 promotes osteosarcoma growth, IGF2 was knocked out in Saos2 cells via CRISPR‐Cas9. KO cells showed reduced proliferation in vitro, and knockout xenografts in mice reached only ~25% of wild‐type tumor volume. Insulin‐like growth factor 2 (IGF2) is implicated in osteosarcoma, but direct functional evidence of its role is ...

Investigation on the effect of opening position across an isolated building for wind-driven cross ventilation

Journal of Mechanical Engineering and Sciences, 2021
This study investigates the effect of opening position on the indoor airflow of a natural ventilated isolated building model. Furthermore, the opening configuration which generate the highest ventilation is to be determined.
