Development and application of an inexpensive open-source dendrometer for detecting xylem water potential and radial stem growth at high spatial and temporal resolution.

There is currently a need for inexpensive, continuous, non-destructive water potential measurements at high temporal resolution (<1 min). We describe here the development and testing of an entirely open-source dendrometer that, when combined with periodic Scholander pressure chamber measurements, provides sub-minute resolution estimates of water potential when placed on tissues exhibiting little or no secondary growth (petioles, monocotyledon stems). The dendrometer can also be used to measure radial growth of stems and branches when placed on dicotyledon and gymnosperm species.

Lessons from innovation in medical education during the COVID-19 pandemic: student perspectives on distributed training.

Introduction: Can the forced adaptation brought about by COVID-19 inform the future of clinical education? This study brings a low- and middle-income country perspective to this question. Most studies of the impact of COVID-19 on medical students' training have been conducted in high-income countries, where the infrastructure to convert to alternative virtual or COVID-19-friendly training platforms (online teaching or case discussions and skill development centres) is more established than in low- and middle-income countries. In South Africa, Stellenbosch University instead chose to move substantial components of clinical training away from the traditional city tertiary campus and into smaller district hospitals.

Advances in the Xenopus immunome: Diversification, expansion, and contraction.

Xenopus is a genus of African clawed frogs including two species, X. tropicalis and X. laevis that are extensively used in experimental biology, immunology, and biomedical studies.

Reduced Flavin in Aqueous Solution Is Nonfluorescent.

Flavins are blue-light-absorbing chromophores with rich redox activity. Biologically, the most important are riboflavin (vitamin B), flavin mononucleotide, and flavin adenine dinucleotide, the latter two of which are catalytic cofactors in enzymes. Flavins pivot between oxidized, one electron-, and two electron-reduced forms in different protonation states, depending on enzymatic requirements.
