Gingival overgrowths are lesions which can be seen due to diffe rent reasons. Phenytoin (PHT), the drug used in the treatment of epilepsy, is probably one of the commonest causes of gingival overgrowth. In the presented case, a male patient aged 23, who has been taking PHT for the treatment of epilepsy, subsequently manifested by the enlarged gingival tissue, which was cut out using gingivectom...

ABO histo-blood group antigens have been postulated to modify pathogen spread through the action of natural antibodies and complement. The antigens are generated by a polymorphic glycosyl-transferase encoded by 2 dominant active and a recessive inactive allele. In this study we investigated whether ABO sugars are incorporated into the envelope of HIV-1 virions. HIV vectors derived from cells ex...

The primary pathogens related to shellfish-borne gastroenteritis outbreaks are noroviruses. These viruses show persistence in oysters, which suggests an active mechanism of virus concentration. We investigated whether Norwalk virus or viruslike particles bind specifically to oyster tissues after bioaccumulation or addition to tissue sections. Since noroviruses attach to carbohydrates of the his...

We characterized the binding of 8 Noroviruses (NORs) to histo-blood group antigens (HBGAs) in human saliva using recombinant NOR (rNOR) capsid proteins. Among the 8 rNORs tested, 6 formed viruslike particles (VLPs) when the capsid proteins were expressed in insect cells, all of which revealed variable binding activities with saliva; the remaining 2 rNORs did not form VLPs, and the proteins did ...

The objective of the study was to evaluate the role of ultrasound in evaluation of appendix and to correlate with surgical and histo-pathological findings. This is a prospective study and was carried out between February 2014 to July 2014 at the Department of Radiology, P.D.U. Govt. Medical College and civil hospital, Rajkot. Abdominal ultrasound & Doppler study with clinical & pathological cor...

The ABO histo-blood group, first discovered over a century ago, is found not only in humans but also in many other primate species, with the same genetic variants maintained for at least 20 million years. Polymorphisms in ABO have been associated with susceptibility to a large number of human diseases, from gastric cancers to immune or artery diseases, but the adaptive phenotypes to which the p...

Norovirus (NoV), a member of the family Caliciviridae, is a major cause of acute water- and food-borne nonbacterial gastroenteritis and forms antigenically diverse groups of viruses. Human NoVs are divided into at least three genogroups, genogroups I (GI), GII, and GIV, which contain at least 15, 18, and 1 genotypes, respectively. Except for a few genotypes, all NoVs bind to histo-blood group a...

Hemoglobin degradation is a metabolic process that is central to the growth and maturation of the malaria parasite Plasmodium falciparum. Two aspartic proteases that initiate degradation, plasmepsins (PMs) I and II, have been identified and extensively characterized. Eight additional PM genes are present in the P. falciparum genome. To better understand the enzymology of hemoglobin degradation,...
