The electrochemical oxidation of famciclovir was investigated in pH range 2.0-10.0 using differential pulse voltammetry at boron-doped diamond electrode. experimental results from and scan rate studies showed that the behavior boron doped electrode irreversible diffusion-controlled. Also, by technique electrode, anodic peak current is obtained to be linear over concentration 0.5 µM - 12 6 100 4...

A quantitative TaqMn Real-Time PCR assay was developed and its diagnostic value on human serum and livestock samples were evaluated. Brucella species could be distributed through communities as a biological agent. Rapid detection of biological threat agents is critical for timely therapeutic administration. Quantitative real-time PCR provides a rapid, sensitive and specific tool for molecular i...

We conducted a survey in Cambodia in 2000 on henipavirus infection among several bat species, including flying foxes, and persons exposed to these animals. Among 1,072 bat serum samples tested by enzyme-linked immunosorbent assay, antibodies reactive to Nipah virus (NiV) antigen were detected only in Pteropus lylei species; Cynopterus sphinx, Hipposideros larvatus, Scotophilus kuhlii, Chaerepho...

a capillary electrophoresis method was used for assay of some degradation products of carvedilol. the optimized parameters were as; running buffer 80 mm acetate dissolved in methanol/ethanol mixture (65:35 v/v), applied voltage of 19 kv, temperature is 20 ºc and the wavelength range of 200-350 nm. the results indicate that the proposed ce method could effectively separate carvedilol from its de...

background: visceral leishmaniasis (vl) as one of the most important human parasitic disease is endemic in some parts of iran. several cases of vl have been reported recently in the ilam province. the current study aimed to assess the pre-sent status of human vl in the region. methods: a random cluster sampling method was used to collect 456 serums samples from the children up to 12 years of ag...

We have developed a microtechnique for detection of streptococcal serum opacity factor (OF) and for typing of group A streptococci by inhibition of OF. This technique, which involves the use of single wells of standard 96-well tissue culture plates, offers several advantages over previous methods: no advance test preparation is required, allowing tests to be quickly and easily performed; only s...

Chemical cross-linking combined with mass spectrometry has proven useful for studying protein-protein interactions and protein structure, however the low density of cross-link data has so far precluded its use in determining structures de novo. Cross-linking density has been typically limited by the chemical selectivity of the standard cross-linking reagents that are commonly used for protein c...

Hepatocellular carcinoma (HCC) is one of the most common human malignancies. Therefore, developing the early, high-sensitivity diagnostic biomarkers to prevent HCC is urgently needed. Serum a-fetoprotein (AFP), the clinical biomarker in current use, is elevated in only ~60% of patients with HCC; therefore, identification of additional biomarkers is expected to have a significant impact on publi...
