Project description:Analysis of human peripheral blood 48 hours after irradiation ex vivo with graded doses of gamma rays. Results have been used in building and testing classifiers to predict exposure dose for use in radiological triage, and also provide insight into immune cell responses. Results were compared with those from earlier times and from patients exposed in vivo. Peripheral blood from 5 healthy donors was exposed ex vivo to 0. 0.5, 2, 5, or 8 Gy gamma-rays and gene expression was analyzed up to 48 hours after exposure.
Project description:Orangutans are an endangered species whose natural habitats are restricted to the Southeast Asian islands of Borneo and Sumatra. For potential species conservation and functional genomics studies, we derived induced pluripotent stem cells (iPSCs) from cryopreserved skin fibroblasts obtained from captive orangutans. We report the gene expression profiles of iPSCs and skin fibroblasts derived from orangtuans.
Project description:In the ex situ conservation of chondrycthyan species, successful reproduction in aquaria is essential. However, aquatic species often exhibit reduced reproductive success under human care. Different factors, including water temperature, nutrition, and intrinsic genetic and epigenetic elements, influence their fertility. Conventional sperm analyses do not provide insights into the functional competence of semen. Therefore, proteomics is gaining relevance, increasing a better understanding of male physiology. In this study, we investigated the proteomic profiles of seminal plasma and spermatozoa from small-spotted catsharks in two different environments: natural environment and aquarium environment.
