Many plant cell functions, including cell morphogenesis and anisotropic growth, rely on the self-organisation of cortical microtubules into aligned arrays with the correct orientation. An important ongoing debate is how cell geometry, wall mechanical stresses, and other internal and external cues are integrated to determine the orientation of the cortical array. Here, we demonstrate that microtubule-based nucleation can markedly shift the balance between these often competing directional cues.

We previously demonstrated the CFTR correctors VX-445 (elexacaftor) and S-VX-121 (vanzacaftor) potentiate heterologously-expressed BK channels, as well as in primary human bronchial epithelial cells (HBEs). This potentiation of BK resulted in altered vasoreactivity and neuronal excitability. We postulated novel compounds could be identified that would potentiate BK while not affecting CFTR.

Background: South Africa faces emerging resistance to TB drugs like bedaquiline. Phenotypic drug susceptibility testing (DST), the current reference standard for bedaquiline DST, has long turnaround times. Targeted next-generation sequencing (tNGS) offers a comprehensive alternative, potentially delivering faster results.

Introduction: Current commercial cerebral oximeters only monitor the frontal lobes, however, some cerebrovascular territories may experience ischemia while others remain well perfused. This pilot study used a novel, high-density, dual-wavelength, time-resolved functional cerebral oximeter (Kernel Flow) with 2000 channels to assess the regional differences of cerebral oxygenation (StO2) in response to hypotension across different vascular territories during shoulder surgery in the beach chair position.
Methods: Twenty-seven adult patients were monitored, recording blood pressure, heart rate, regional cerebral oxygen saturation, and other vital parameters.
