The pyridoxal-5'-phosphate (PLP)-dependent family of enzymes is a very diverse group of proteins that metabolize small molecules like amino acids and sugars, and synthesize cofactors for other metabolic pathways through transamination, decarboxylation, racemization, and substitution reactions. In this study we employed degenerated primer-based PCR amplification, using genomic DNA isolated from ...

OBJECTIVE This study was to identify small inhibitory RNAs (siRNAs) that are effective in inhibiting growth of cervical cancer cell lines harboring human papilloma virus (HPV) and to examine how siRNAs interact with interferon beta (IFN-β) and thimerosal. METHODS The HPV18-positive HeLa and C-4I cell lines were used. Four types of siRNAs were designed according to their target (both E6 and E7...

Plasma-cell neoplasms are classically categorized into four groups as: multiple myeloma (MM), plasma-cell leukemias, solitary plasmacytomas (SP) of the bone (SPB), and extramedullary plasmacytomas (EMP). These tumors may be described as localized or diffuse in presentation. Localized plasma-cell neoplasms are rare, and include SP of the skeletal system, accounting for 2-5% of all plasma-cell ne...

BACKGROUND AND PURPOSE Because tonic production of nitric oxide (NO) is important in regulating cerebrovascular tone and NO may be important in the mechanism of brain injury from focal ischemia, we speculated that stroke predisposition in spontaneously hypertensive stroke-prone rats (SHR-SP) may be related to impaired tonic production of NO. This study was designed to test the hypothesis that t...

The current study was attempted to isolate and characterize the protease producing Bacillus sp. Among the 3 strains isolated from soil sample collected from kuppam region, Chennai, India. One strain (PR01) exhibited potent proteolytic activity. Based on the morphological, biochemical and molecular characterization, the isolate (PR01) was identified as Bacillus sp. The strain was designated as B...
