Untargeted Nuclear Magnetic Resonance (NMR) metabolomics of polar extracts from the pancreata of a caerulin-induced mouse model of pancreatitis (Pt) and of a transgenic mouse model of pancreatic cancer (PCa) were used to find...
Organization of residential space, site function variability, and seasonality of activities among MIS 5 Iberian Neandertals.
Whether ethnoarcheological models of hunter-gatherer mobility, landscape use, and structuration of the inhabited space are relevant to the archeology of Neandertals and the Middle Paleolithic remains controversial. The thin...
Testicular organoid generation by a novel in vitro three-layer gradient system.
A system that models the testicular microenvironment and spermatogonial stem-cell (SSC) niche in vitro has not been produced yet. Here, we developed and characterized a novel three-dimensional multilayer model, the Three-Layer...
