hepatitis delta virus (hdv) is a degenerate rna virus or virusoid and a satellite of hepatitis b virus (hbv). three distinct genotypes are described for hdv; genotype i is distributed worldwide but other genotypes appear to be more restricted geographically. in the present study, an rt-nested pcr method was set up to detect delta infection from serum samples. moreover, the target amplified sequ...

in this paper, we firstly show that the $n$-dual operation of the right residual implication, which is induced by a left-conjunctive right arbitrary $vee$-distributive left semi-uninorm, is the right residual coimplication induced by its $n$-dual operation. as a dual result, the $n$-dual operation of the right residual coimplication, which is induced by a left-disjunctive right arbitrary $wedge...

introduction: gutta-percha (gp), is a neutral and non-toxic material. the aim of this animal study was to compare the biocompatibility of nanosilver coated gp (ns-gp) with conventional gp in subcutaneous tissues in a rat model. methods and materials: conventional gp and ns-gp were subcutaneously implanted in the backs of 20 male wistar rats ( n =10). a control animal was assigned for each trial...

statement of problem: various surgical procedures have been used to achieve root coverage and subepithelial connective tissue graft (sctg) is identified as one of the most successful techniques. recently, acellular dermal matrix allograft (adma) has been developed as a substitute for sctg to avoid removing the palatal connective tissue. purpose: the present study compared the clinical efficienc...

the b cell is a vital contributor to humoral immunity. the b cell-specific antigen cd20 is expressed during b cell development, starting at the pre-b cell level and persists through b cell differentiation, but is lost during terminal differentiation to plasma cells. rituximab is a monoclonal antibody that destroys both normal and malignant b cells that have cd20 on their surfaces and is therefo...
