The project's aim is to verify the existence of Herero and Nama skulls among the roughly 1370 skulls in the Alexander Ecker collection (AEC). Methods include historical research, which was mainly concerned with the AEC and especially Eugen Fischer during his time as curator, as well as the methods of acquisition of human remains and scientific methods to verify the identity of the relevant skulls. Scientific methods include morphological sex and age-at-death verification, morphological estimation of ancestry, morphometric analysis and the application of UV light to decipher old labels on the skull surfaces, as well as a molecular biology approach (mtDNA) and stable isotope analyses. Out of 19 preselected skulls, 14 revealed a significant probability for a Herero/Nama ancestry, although identification of specific skulls according to the historical documentation was not possible.

Female mosquitoes require a vertebrate blood meal to activate reproduction, transmitting numerous devastating human diseases. Vitellogenesis is a central event of female reproduction that involves the massive production of vitellogenin (Vg) in the fat body and the maturation of ovaries. This process is controlled by the steroid hormone 20-hydroxyecdysone (20E); however, its molecular regulatory basis remains not completely understood.

Diffraction imaging of cells allows rapid phenotyping by the response of intracellular molecules to coherent illumination. However, its ability to distinguish numerous types of human leukocytes remains to be investigated. Here, we show that accurate classification of three lymphocyte subtypes can be achieved with features extracted from cross-polarized diffraction image (p-DI) pairs.

The rise in global obesity prevalence has increased the need to understand the pharmacokinetics of drugs in overweight and obese individuals. Tuberculosis remains a significant health challenge, and its treatment outcomes can be influenced by the pharmacokinetic profiles of antitubercular agents. This literature review aims to point out the clinical pharmacokinetics of antitubercular drugs in the overweight and obese patient population, highlighting considerations for potential dosage adjustments.

Purpose: Sulfur mustard gas (SM) exposure to eyes causes multiple corneal injuries including stromal cell loss in vivo. However, mechanisms mediating stromal cell loss/death remains elusive. This study sought to test the novel hypothesis that SM-induced toxicity to human corneal stromal fibroblasts involves ferroptosis mechanism via p38 MAPK signaling.

Overweight and obesity are associated with adverse psychological outcomes, compromised body composition, and reduced quality of life (QoL). While exercise training has been proposed as an effective intervention, its impact on these outcomes remains unclear. This systematic review and meta-analysis evaluated the effects of exercise training on psychological outcomes, body composition, and QoL in overweight or obese adults.
