A promoterless chloramphenicol acetyltransferase gene (cat) was used to construct recA-cat operon fusions to quantitatively examine the transcriptional regulation of the Pseudomonas aeruginosa recA gene in P. aeruginosa PAO. Wild-type P. aeruginosa containing the recA8-cat fusion was treated with methyl methanesulfonate (MMS) and showed immediate induction of chloramphenicol acetyltransferase (...

objectives the aim of this study was to perform a histopathological and bacteriological evaluation of gastric lesions based on h. pylori and helicobacter-like organisms (hlos) in cats. materials and methods the present study was carried out on 28 cat’s (13 male and 15 female cases) gastric mucosae, which were tested by bacteriological and histopathological methods. biochemical tests such as cat...

background: toxocara is a common nematode of cats in different parts of iran. despite the close association of cats with human, no attempt has been done so far for molecular identification of this nematode in the country. therefore, current study was performed on identification of some isolates of toxocara from stray cats in shiraz, fars province, southern iran, based on morphological and molec...

pregnancy prevention raises much concern to many pet owners. female cats usually show undesirable behaviour during oestrus. nowadays, researchers try to explore the reliable and effective ways to prevent oestrus signs in queens. the results of their studies prove that hormone therapy is probably one of the most reliable methods for this purpose. the aim of our study was to compare the effect of...

we aimed to investigate the efficacy of coping cat protocol on coping strategies of girls and boys with internalized disorders. a true experimental method in the form of pre-test and post-test. the study population consisted of all children with internalized disorders in tehran. the sample consisted of 80 children aged 9 to 11 years (40 boys and 40girls) with internalized disorders were based o...

the aim of this study was to determine whether anesthesia consisting of sedation induced by intramuscular administration of xylazine-diazepam and lumbosacral analgesia induced by epidural administration of lidocaine and xylazine is satisfactory for castration and ovariohysterectomy in cats. six adult (3 male and 3 female, 2.5 ± 0.5 years of age) cats (mean body weight ± sd, 2.2 ± 0.44 kg) were ...

despite the preventative and therapeutic effects of regular exercise, exhaustive exercise may be harmful to health. the present study aimed to determine the protective effect of endurance training and cinnamon bark extract (cbe) supplementation on oxidative responses induced by an exhaustive exercise schedule in rats. the rats were randomly divided into the following five groups of 6; control s...

the catalytic cracking of a fuel oil over fluid catalytic cracking (fcc) catalyst has been investigated applying different additives. catalyst mixtures consisting of a equilibrium fcc catalyst (e-cat) blended with zsm-5, mcm-41 and mordenite additives were examined at the additive levels of 25 wt.%. the catalytic performance of the matrix was studied in a fixed bed micro-activity test unit (mat...
