The properties of nanowires are distinctively different from those of bulk materials because they are affected by quantum confinement effect and large surface-to-volume ratios. A fundamental understanding of the intrinsic properties of nanowires, in terms of their structure, electronic and optical properties as well as a study of the nanowire surface is required to develop them for future devic...

A 65-year-old female presenting with hepatobiliary cystadenoma (HC) comprised of multiple cysts in the liver and a non-specific epigastric pain is reported herein.  Ultrasound study demonstrated dilated common bile duct (CBD) and intrahepatic bile ducts, plus two spherical stone-like bodies filling defects in the proximal CBD. Sphincterotomy and basket performed for the patient were not success...

context this article reviews the available evidence about the barrier membranes utilized in guided tissue regeneration process to prevent the migration of unfavorable cells to the wound area. evidence acquisition available evidence about membranes properties and their different uses were reviewed, and the results of clinical and animal studies and systematic reviews were gathered. results a lar...

Different from canonical ubiquitin-like proteins, Hub1 does not form covalent conjugates with substrates but binds proteins non-covalently. In Saccharomyces cerevisiae, Hub1 associates with spliceosomes and mediates alternative splicing of SRC1, without affecting pre-mRNA splicing generally. Human Hub1 is highly similar to its yeast homolog, but its cellular function remains largely unexplored....

background: excess reactive oxygen species (ros) in the semen is believed to affect fertility in men. morphologically abnormal sperms and their relation to seminal oxidative stress in infertile and subfertile men are not clear. objective: to correlate various sperm morphological defects with seminal oxidative stress in infertile and subfertile men. materials and methods: the study included 25 p...

Hemophagocytic lymphohistiocytosis (HLH) and macrophage activation syndrome (MAS) are 2 similar diseases characterized by a cytokine storm, overwhelming inflammation, multiorgan dysfunction, and death. Animal models of HLH suggest that disease is driven by IFN-γ produced by CD8⁺ lymphocytes stimulated by persistent antigen exposure. In these models and patients with "primary" HLH, the antigen p...
