background and aims: epstein-barr (ebv) virus infection is very common in the population. virus belongs to the family herpesviridae, whose representatives are characterized by the ability to cause the human body latent persistent infections. the goal of study is to assess ebv infection frequency and pcr method in the choice of ebv in inflammatory eye disease, comparing with ebv presence in eye ...

background chronic hepatitis b virus (hbv) infection has a broad spectrum of manifestation, ranging from silent carrier state to advanced cirrhosis and hepatocellular carcinoma. the persistence of hbv dna in serum and hepatocytes of the cirrhotic patient could be detected by molecular techniques in spite of negative hbv serologic markers. conclusions the prevalence of obi was relatively high in...

Background: Varicoceles are the abnormal tortuosity and dilatation of the veins of the pampiniform plexus that drain the testis. Recently, studies evaluating the role of oxidative stress in male infertility have shown that infertile men with varicocele have elevated levels of sperm and testicular tissue-derived reactive oxygen species (ROS). Therefore current study was designed to evaluate prot...

Background The current study aimed to evaluate the effects of phosalone (PLN) as an organophosphate (OP) compound on testicular tissue, hormonal alterations and embryo development in rats. MaterialsAndMethods In this experimental study, we divided 18 mature Wistar rats into three groups-control, control-sham and test (n=6 per group). Animals in the test group received one-fourth the lethal dose...

The assembly of adaptive hierarchical soft materials that resemble living tissues requires responsive building blocks controlled dimensions. While DNA self-assembly provides an exceptional tool for nanoscale architectural control, microstructures remain scarce. Here, two challenges controlling the size and embedding them with fast ample structural response are addressed. For size-control, arres...
