a preliminary study on statistical modelling of a process for depolymerisation of cassava non-starch carbohydrate using halide salt assisted phosphoric and pyruvic acids were accomplished. the effects of three independent variables namely; acid concentration, potassium iodide salt and duration were studied using the central composite rotatable design on hydrolysis of the cassava non-starch carb...

background: to determine the colon transit time (ctt) in patients complaining of functional constipation and to evaluate the correlation between abnormal transit times and the types of constipation and the correlation with age and sex. materials and methods: the signs and symptoms of 84 patients with infrequent or difficult defecation, 33 males and 51 females, with a median age of 33.7 were rec...

background: as for human trichomoniasis the host-parasite relationship is very complex, and the broad ranges of clinical symptoms are unlikely be attributable to a single pathogenic mechanism. specific random amplified polymorphic dna (rapd) markers of 490 bp, 720 bp and 460 bp using the primers tv-5, opa-6 and opa-11, respectively, were reported. this was the first description of possible ge­n...

in this study, srap molecular maker approach was performed to investigate genetic diversity in the salvia genus. a total of 205 dna bands were produced from pcr amplification of 11 salvia species and populations using 25 selective primer combinations, of which 204 polymorphic genetic loci accounted. the total number of amplified fragments ranged from 3 to 15. the genetic similarities of 11 coll...

objective: dna markers are one of the most important indicators for estimating molecular weight of dna samples, although it used in widespread medical and research laboratories. these markers are very divers and have been prepared in different manners and from different sources of dna. but unfortunately, dna markers haven't been made in our country and all of the markers that we use are made in...

pyramiding genes related to grain quality and resistance through marker assisted selection (mas) is an important approach in rice breeding programs. marker-assisted selection can be used for monitoring the presence or absence of these genes in breeding populations and can be combined with conventional breeding approaches. this study is a part of cultivar development program in iran through inte...

background autism spectrum disorder (asd) is a intricate childhood neuropsychiatric disorder that is described by deficits in communication of verbal and non-verbal, reciprocal social interactions, stereotypic behaviors, interests, and activities. the studies of post-mortem neuro-anatomical anomalies have indicated that migration alterations could occur early during development (first trimester...

background: cockroaches are of vital importance medically and hygienically as they can disperse human patho­genic agents and are especially responsible for food contamination and spreading of food borne pathogens. in this study, part of mtdna-coi gene of five common pest cockroaches was tested for diagnostic and phylogenetic pur­poses. methods: we have described barcode region of mtdna-coi gene...
