Sequence Analysis of the RNA Polymerase Gene of Foot-and-Mouth Disease Virus Serotype Asia1

The complete nucleotide (nt.) sequence of the RNA polymerase (3D) gene and 81 nt. in the 3-untranslated region of foot-and-mouth disease virus (FMDV) serotype Asia1 (IND63/72) was determined and compared with the sequence of other FMDV serotypes. The 3D genomic region was 1410 nt. long encoding 470 amino acids with an inframe stop codon (TAA) at nt. position 1411–1413. The deduced amino acid sequence of the protein showed 8 conserved motifs as reported in other picornaviruses, 2 of which are 100% identical across the serotypes. Antigenic regions in the polymerase protein were predicted and found to be located at the N-terminus of the protein. The phylogenetic analysis showed that the FMD viruses were segregated into different clusters based on geographical origin; the Asia1 virus did not cluster tightly with any of the geographical groups.     

Expression of PDZ-binding kinase/T-LAK cell-originated protein kinase (PBK/TOPK) in human urinary bladder transitional cell carcinoma

The objective of this study was to evaluate the expression pattern of PDZ-binding kinase/T-LAK cell-originated protein kinase (PBK/TOPK) and its clinical significance in human bladder cancer (BC).     

Pesticide-induced physiological alterations in certain tissues of a fish, Mystus vittatus

Effect of sublethal concentrations (1/5, 1/10 and 1/15 fractions of 96-h TL50) of thiotox, dichlorvos and carbofuran on acid, alkaline and glucose-6-phosphatase of liver, kidney and gills of Mystus vittatus have been studied. Maximum (62.79%) inhibition of alkaline phosphatase in gills after thiotox (0.00013 mg/l) treatment have been observed. At 0.000045mg/l concentrations of thiotox, a marginal (7.6%) and significant (P less than 0.01) stimulation was observed in hepatic alkaline phosphatase activity.     

Prostate cancer: altering the natural history by dietary changes

The importance of diet on the development and progression of prostate cancer was initially suggested by epidemiological studies. Since then, there has been a vast amount of research in this field. Compelling evidence now provides hope that evidence-based dietary alterations may markedly alter the natural history of this disease. Is there enough evidence for clinicians to be able to advise dietary modifications? The preliminary results no doubt are encouraging, but at present there seems to be no evidence to justify the widespread use of these proposed dietary interventions. However, as public awareness increases, all physicians involved with the care of patients with cancer of the prostate will need to be better armed with the current updates and advice on this issue.
