b a ckground: anoph eles fluviatilis , one of the major malaria vectors in iran, is assumed to be a complex of sibling species. the aim of this study was to evaluate cytochrome oxidase i (coi) gene alongside 28s-d3 as a diagnostic tool for identification of an. fluviatilis sibling species in iran. m e t hods: dna sample belonging to 24 an. fluviatilis mosquitoes from different geographical area...

bemisia tabaci (gennadius) (hemiptera: aleyrodidae), is one of the most important pest of vegetable and fruit crops. this polyphagous pest has a range of natural enemies including the parasitoid eretmocerus mundus (merect) (hymenoptera: aphelinidae). to determine the molecular profile and taxonomic status of iranian isolates of e. mundus, parasitized b. tabaci samples were collected from cotton...

it has been known that cardiomyocytes possess a remarkable ability to downregulate their energy expenditure on restricted 02 supply. however it has also been speculated that an ability to suppress aerobic respiration and atp utilization could be a protective response to prolonged hypoxia. having the role of the cytochrome oxidase enzyme in mind, one can ask if its inhibition by using cyanide ha...

this study pursued the molecular identification of fish species from processed products for human consumption which, a priori, belonged to nine species. dna barcoding using direct sequencing of about 650 bp of the mitochondrial gene cytochrome oxidase subunit i (coi) revealed incorrect labeling in the three alaska pollack samples (11% of all samples). substitution of fish species constitutes se...

research has shown that chronic, long and exhausting endurance training programs cause iron deficiency. this problem can have a negative effect on physical performance. the aim of this research was to study the effect of endurance training and iron supplement on anemic indexes [hemoglobin (hb), hematocrit (hct), red blood cell (rbc), total iron binding capacity (tcbc) and ferritin], and cytochr...

Three distinct types of terminal oxidases participate in the aerobic respiratory pathways of Paracoccus denitrificans. Two alternative genes encoding sub unit I of the aa3 -type cytochrome c oxidase have been isolated before, namely ctaDI and ctaDII. Each of these genes can be expressed separately to complement a double mutant (ActaDI, ActaDII), indicating that they are isoforms of subunit I of...

OBJECTIVE Cyanotic patients have potentially decreased tissue oxygen tension. Cytochrome oxidase catalyzes the reduction of oxygen and is integral to adenosine triphosphate production. Cytochrome oxidase subunit I, the active site, is encoded by mitochondrial DNA. Using a newborn swine model of chronic hypoxemia, we evaluated ventricular cytochrome oxidase subunit I mRNA and protein expression ...
