Three short protein sequences have been guided by computer to folds resembling their crystal structures. Initially, peptide fragment conformations ranging in size from 9 to 25 residues were selected from a database of known protein structures. A fragment was selected if it was compatible with a segment of the sequence to be folded, as judged by three-dimensional profile scores. By linking the s...
Canine visceral leishmaniasis (CVL) is endemic in northwestern Iran. This study aimed to compare real-time PCR, conventional PCR, and the direct agglutination test (DAT) for the diagnosis Leishmania infantum infection in 167 serum samples of domestic dog. Bone marrow was used for parasitological examination (smears and/or culture) in symptomatic visceral leishmaniasis, and serum was used for de...
The thermodynamic parameters for six p53 carboxy-terminus peptide fragments as determined by analytical ultracentrifugal analysis were compared over the experimental temperature range of 275-310 K to evaluate the Gibbs free energy change as a function of temperature, ΔG°(T), from 0 to 400 K using our general linear third-order fitting function, ΔG°(T) = α + βT² + γT³. Data obtained at the typic...
BACKGROUND A century after its discovery, Chagas disease still represents a major neglected tropical threat. Accurate diagnostics tools as well as surrogate markers of parasitological response to treatment are research priorities in the field. The purpose of this study was to evaluate the performance of PCR methods in detection of Trypanosoma cruzi DNA by an external quality evaluation. METHO...
We studied the intramitochondrial localization of several multiprotein complexes involved in U-insertion/deletion RNA editing in trypanosome mitochondria. The editing complexes are located in one or two antipodal nodes adjacent to the kinetoplast DNA (kDNA) disk, which are distinct from but associated with the minicircle catenation nodes. In some cases the proteins are in a bilateral sheet conf...
long-term complications of retained war fragments in the body are not completely known. also, bullet migration and slow resorption of metals and distortion in some imaging modalities are frequent and well recognized complications but, now we are concerned about neoplastic changes near the retained war fragments. we reviewed the literature on complication of retained war fragments and report our...
abstract background and objective: chabahar is in southern iran located near the iran-pakistan border. since leishmaniasis is an emerging disease in this region, this study aimed to diagnose the disease and identify different species of leishmania parasite in the patients referred to the central laboratory. methods: this descriptive cross-sectional study was conducted in 2011-2012 ...
