Hepatocellular carcinoma (HCC) is a deadly and emerging disease leading to death in Asian countries. High hepatitis B virus (HBV) load and chronic hepatitis B (CHB) infection increase the risk of developing HCC. HBV is a DNA virus that can integrate DNA into host genome thereby increase the yield of transactivator protein HBxAg that may deregulate many(More)
Classically Salmonella enterica serovar Typhi (S. Typhi) is associated with typhoid, a major health problem in developing countries. However, in recent years S. Paratyphi A and Vi-negative variants of S. Typhi have emerged rapidly. We have developed a nested multiplex PCR targeting five different genes for differential diagnosis of typhoidal pathogens which(More)
The synthesis and transportation proteins of the Vi capsular polysaccharide of Salmonella enterica serovar Typhi (serovar Typhi) are encoded by the viaB operon, which resides on a 134-kb pathogenicity island known as SPI-7. In recent years, Vi-negative strains of serovar Typhi have been reported in regions where typhoid fever is endemic. However, because Vi(More)
Typhoid is a global problem. Conventional diagnostic methods have limitations. The Widal test gives a high proportion of false positive results, and indiscriminate use of antibiotics has reduced the utility of blood culture. Consequently, these procedures are inadequate for diagnosing suspected cases of typhoid that do not present clear-cut symptoms. We(More)
Wheat is a vital dietary component for human health and widely consumed in the world. Wheat rusts are dangerous pathogens and contribute serious threat to its production. In present study, PCR-Based DNA Markers were employed to check the rust resistance genes among 20 wheat genotypes and 22 markers were amplified. NTSYS-pc 2.2 was used to calculate genetic(More)
Background: Gram negative bacteria especially members of family Enterobacteriaceae are among the most frequently isolated organisms from the clinical specimens. Rapid diagnosis of the pathogen in a clinical sample is always very important. Conventional methods are time-consuming. Among molecular techniques, PCR is very useful but unless very specific(More)
OBJECTIVES We hypothesized that Salmonella enterica serovar Typhi (S. Typhi) with higher biofilm and capsule production capability are more able to survive continuously in typhoid patients/carriers, with subsequent prolonged shedding in feces. METHODS Bacterial cell release from biofilm (produced in vitro and confirmed by specific staining and electron(More)
Amounts of DNA damage and homocysteine (Hcy) in heart patients blood may have strong function in the causation of cardiovascular disease (CVD). The main objective of this work was to know experimentally the role of total oxidants (produced by Reactive Oxygen species (ROS), clinical biochemical indices, their oxidized products and total antioxidant status(More)
Bacterial infection is found to be the cause of death throughout the world. Nuclear medicine imaging with the help of radiopharmaceuticals has great potential for treating infections. In the present work, clindamycin, a lincosamide antibiotic, was labeled with technetium-99 m (~380 MBq). Clindamycin has been proven to be efficient for treating serious(More)
The dengue virus (DENV) genome encodes 10 different genes including the NS3 gene, which has a protease and helicase domain used in virus replication. This domain is a potential target for antiviral agents against dengue. Due to a high mutation rate, DENV is classified into four major serotypes (DENV1-DENV4). This study was designed to perform conservancy(More)
