crude oil is enriched in polycyclic aromatic hydrocarbons (pahs). many pah analogs have proved to potentially damage dna. dna damage can be assessed using various biomarkers to find out the degree of genotoxicity of pollutants following in vitro exposure. in this research the comet assay and micronucleus (mn) test were used to detect dna damages and cytogenetic changes following crude oil expos...

conclusions b. oleracea demonstrated similar anti-inflammatory properties to omeprazole in rats with gerd. however, omeprazole also demonstrated genotoxic and cytotoxic effects in rats without gerd. results rats with gerd developed esophagitis and esophageal squamous cell carcinoma. b. oleracea and omeprazole-treated gerd rats presented significantly decreased inflammation in relation to non-tr...

phenolic and flavonoid compounds are secondary metabolites of plants which possess various activities such as anti-inflammatory, analgesic, anti-diabetes and anticancer effects. it has been established that these compounds can scavenge free radicals produced in the body. because of this ability, not only the plants containing phenolic and flavonoid compounds but also, the pure compounds are use...

results: of the 50 samples tested by the elisa method, 26 samples (52%) were positive for igg . no samples were positive for igm. of the 50 samples tested by the chemiluminescence method, 28 samples (56%) were positive for igg. no samples were positive for igm. conclusions: a significant relationship between the age of the youngest child and the infection rate was seen. no significant correlati...

feline infectious peritonitis virus (fipv) is ubiquitous in domestic cats, especially in young cats and multi-cat environments. in the present study, a total of 248 companion cats of different ages were examined for serum antibody detection of fipv by immunochromatography assay. the cats were selected from those referring to veterinary hospital of ahvaz university, southwestern iran from decemb...

background: quantification of radiation-induced apoptosis in peripheral blood lymphocytes (pbls) has been proposed as a possible screening test for cancer-prone individuals and also for the prediction of normal tissue responses after radiotherapy. materials and methods: the neutral version of the comet assay (single-cell gel electrophoresis) was used 24, 48, 72 hours after irradiation with 8 gy...

background: radio-adaptive response and bystander effects are known phenomena occurring in cells following exposure to ionizing radiation (ir). in this study we examined possible radio-adaptation of lymphocytes following bystander effects induced by cho-k1 cells. materials and methods: whole blood and cho-k1 cells were cultured in rpmi-1640 complete medium. cells were separately irradiated with...

background: boron and gadolinium are among the nuclides that hold a unique property of being a neutron capture therapy agent. neutron beams have often a considerable portion of gamma rays with fast neutrons. gamma rays, as beam contaminants, can cause considerable damage to normal tissues even if such tissues do contain high boron concentrations. materials and methods: the modification of radio...

objective: bacterial meningitis is a dangerous and sometimes fatal infection that affects the central nervous system. because some antibiotics can prevent some types of these bacteria and supress them from spreading and infecting, therefore it is important to know what type of virus or bacterium is causing meningitis. haemophilus influenzae and neisseria meningitides are the two main pathogens...
