Capsaicin (CAP)-activated ion channel plays a key role in generating nociceptive neural signals in sensory neurons. Here we present evidence that intracellular ATP upregulates the activity of capsaicin receptor channel. In inside-out membrane patches isolated from sensory neurons, application of CAP activated a nonselective cation channel (i(cap)). Further addition of ATP to the bath caused a s...

BACKGROUND Trans rectal ultrasound guided prostate biopsy (TRUS) was introduced to Sri Lanka in 2002. OBJECTIVES 1. To study clinicopathological features of males subjected to TRUS biopsy 2. To compare estimation of tumour burden by two methods in carcinoma prostate (CaP). METHODS 749 symptomatic males subjected to TRUS biopsy over 64 months at a single centre. Information was retrieved fro...

We demonstrate that the immediate early 175K protein (IE175K) of herpes simplex virus type 1 binds to the cap site of the latency-associated promoter (LAP) in an unusual manner. The complex formed on the LAP cap site was significantly larger than that formed on the IE175K cap site and the requirements for binding were qualitatively distinct with respect to both the primary sequence determinants...

OBJECTIVE Thalassemia is one of the most common genetic disorders worldwide. Cap +1 mutation which causes 'silent beta thalassemia' is present around all ethnic groups of Pakistan. This study was designed to detect the frequency of Cap+1 mutation in Pakistani Population. METHODS Molecular genetic for Cap+1 beta thalassemic mutation was done by extracting DNA from whole blood by using Genomic ...

Despite recent advances, treatment options for advanced prostate cancer (CaP) remain limited. We are pioneering approaches to treat advanced CaP that employ conditionally replication-competent oncolytic adenoviruses that simultaneously produce a systemically active cancer-specific therapeutic cytokine, mda-7/IL-24, Cancer Terminator Viruses (CTV). A truncated version of the CCN1/CYR61 gene prom...

The cytoplasmic inheritance of human chloramphenicol (cap) resistance has been demonstrated by removing the nuclei of cells of the CAP-resistant HeLa strain 296-1 (enucleation) and fusing them to a CAP-sensitive HeLa strain lacking nuclear thymidine kinase. Plating the fusion products in bromodeoxyuridine and CAP resulted in the growth of about 150 colonies/10(6) parent cells plated. Permanent ...

BACKGROUND Several commercially available molecular techniques were developed based on subtype B of HIV-1, which represents only 10% of HIV strains worldwide. Indeed, in sub-Saharan Africa, non-B subtypes of HIV-1 are predominant. The aim of this study was to evaluate the performances of the COBAS® AmpliPrep/COBAS® (CAP/CTM) HIV-1 Qualitative assays to detect the broad range of HIV-1 variants c...

The influence of electrical stimulation on the amplitude of the action potentials recorded from the mouse nervous system in vitro was investigated. Brief (1 s) high frequency (100 Hz) stimulation of the sciatic nerve induced a longlasting increase in the amplitude of the compound action potential (CAP). Low frequency (1 Hz) stimulation delivered for 15 min attenuated the antidromically evoked p...

BACKGROUND AND AIMS Monitoring of chronic Hepatitis C (CHC) treatment relies on HCV RNA quantification by means of real-time PCR methods. Assay specific analytical sensitivities may impact therapy management. METHODS Comparative analysis between three commercial assays (Roche COBAS AmpliPrep/COBAS TaqMan Version 1 (CAP/CTM Ver. 1), Version 2 (CAP/CTM Ver. 2) and the Abbott RealTime HCV (ART) ...
