Community Level Physiological Profiles (CLPP) is novel method to evaluate microbial activity and diversity in ecosystems. According to the previous findings, poly-β-hydroxybutyrate (PHB) as a bio-control product, increases bacterial diversity in some aquatic animals. In this study, the effects of four experimental diets (control, combination of two PHB degrading bacteria, 2% PHB, bacteria+ 2% P...
INTRODUCTION To compensate for cell loss, most animal tissues maintain slowly proliferating populations of stem cells that are able to differentiate on demand. Given the great potential of stem cells for the management of many human diseases, it is important to understand in detail the molecular pathways that control the biology of stem cells, including their origin, pattern of proliferation an...
Primordial germ cells (PGCs) are the founder cells of the gametes. In mammals, PGCs migrate from the hindgut to the genital ridges, where they coalesce with each other and with somatic cells to form the primary sex cords. We show here that, in both sexes, PGCs express P- and E-cadherins during and after migration, and N-cadherin at post-migratory stages. E-Cadherin is not expressed by PGCs whil...
Classical descriptions of gut development specify subdivision into foregut, midgut, and hindgut together with their derivatives. This is based on the anatomical localisation of the anterior and posterior intestinal portals separating the roof of the yolk sac from the foregut and hindgut diverticulae. When considering the molecular basis of intestinal differentiation, it is necessary to think in...
We observed expression patterns of hedgehog (hh), wingless (wg), and decapentaplegic (dpp) during gut development of Gryllus bimaculatus (the cricket), a typical hemimetabolous insect, and compared with those observed in Drosophila, a typical holometabolous insect. Gryllus hh(Gbhh) and Gbwg are expressed in both foregut and hindgut, while Gbdpp is expressed only in the hindgut: at the boundarie...
We observed a rare variation of splenic artery during the routine dissection in the Laboratory of the Anatomy Department. It arose from the splenic artery toward the distal part of transverse colon which typically supplied by the inferior mesenteric artery. Embryologically distal part of the transverse colon is a segment of hindgut. In this case, splenic artery which an artery of foregut suppli...
Mammalian herbivores rely on microbial activities in an expanded gut chamber to convert plant biomass into absorbable nutrients. Distinct from ruminants, small herbivores typically have a simple stomach but an enlarged cecum to harbor symbiotic microbes; however, knowledge of this specialized gut structure and characteristics of its microbial contents is limited. Here, we used leaf-eating flyin...
