Strontium isoscape of sub-Saharan Africa allows tracing origins of victims of the transatlantic slave trade.

Strontium isotope (Sr/Sr) analysis with reference to strontium isotope landscapes (Sr isoscapes) allows reconstructing mobility and migration in archaeology, ecology, and forensics. However, despite the vast potential of research involving Sr/Sr analysis particularly in Africa, Sr isoscapes remain unavailable for the largest parts of the continent. Here, we measure the Sr/Sr ratios in 778 environmental samples from 24 African countries and combine this data with published data to model a bioavailable Sr isoscape for sub-Saharan Africa using random forest regression.

Notch signaling stabilizes lengths of motile cilia in multiciliated cells in the lung.

Airway multiciliated cells (MCs) maintain respiratory health by clearing mucus and trapped particles through the beating of motile cilia. While it is known that ciliary lengths decrease along the proximal-distal (P-D) axis of the tracheobronchial tree, how this is regulated is unclear. Here, we demonstrate that canonical Notch signaling in MCs plays a critical role in stabilizing ciliary length.

The Sit Less, Interact and Move More (SLIMM-2) Trial: Protocol for a randomized control trial of a sedentary behavior intervention, resistance training and semaglutide on sedentary behavior in persons with chronic kidney disease.

Background: Sedentary behavior is highly prevalent and associated with morbidity and mortality in chronic kidney disease (CKD). A Sit Less, Interact and Move More (SLIMM) sedentary activity coaching intervention can reduce sedentary duration among persons with CKD, but preliminary data suggest that effects may not persist. Prior studies have suggested that moderate/vigorous intensity physical activities are not sustainable in persons with CKD.

Black Soldier Fly Larvae Meal . Soy Protein Concentrate Meal: A Comparative Digestibility Study in Barramundi ().

Black soldier fly larvae meal (BSFM) from has emerged as a dependable protein source in aquaculture. This study aimed to assess BSFM's digestibility in barramundi juveniles and compare it to soy protein concentrate meal (SPCM). Four diets (control, 30% BSFM; 30% SPCM; and commercial feed control) were tested on 1,800 barramundi juveniles (weight: 71.
