Formation of a dorsoventral axis is a key event in the early development of most animal embryos.It is well established that bone morphogenetic proteins (Bmps) and Wnts are key mediators of dorsoventral patterning in vertebrates.In the cephalochordate amphioxus, genes encoding Bmps and transcription factors downstream of Bmp signaling such as Vent a
The article presents some aspects of developing, within INOE 2000-IHP, of an experimental research on the determination of frictional forces that occur in the mobile sealings of the pistons, between the piston sealings Laserdisc Parts and the inner liner of hydraulic cylinders.In the first part of the paper, are presented some specific elements of
Introduction.Hepatic peribiliary cysts (HPCs) usually originate due to the cystic dilatation of the intrahepatic extramural peribiliary glands.We describe our rare experience of pure laparoscopic left hemihepatectomy (PLLH) in a patient with HPCs accompanied by a component of biliary intraepithelial neoplasia (BilIN).Case Presentation.A 65-year-old
BACKGROUND: Gene expression profiles of bacteria in their natural hosts can provide novel insight into the host-pathogen interactions and molecular determinants of bacterial infections.In the present study, the transcriptional profile of the porcine lung pathogen Actinobacillus pleuropneumoniae was monitored during the acute phase of infection in i
