Abstract
|
| |
The soils are the major source of fungi. Some of the soil fungi can be pathogen to humans and animals. Rich keratinous materials in soil are the most reason for the incidence and growth of keratinophilic fungi. The purpose of this survey was isolation of keratinophilic and dermatophytic fungi from the soil samples which can be pathogen to humans and animals. Forty-five soil samples were collected from three different locations in Ahvaz, Khuzestan province, Iran. The isolated fungi were identified after slide culturing according to studies of their gross and micro-morphological features... |

Abstract
|
| |
Cryptosporidium parvum is an intracellular, extracytoplasmic, zoonotic, coccidian parasite that infects the microvillus regions of the digestive tract, and respiratory tract and causes lethal disease mainly among individuals suffering from immune deficiency and children. Suitable animal models are needed to identify different aspects of Cryptosporidium infection and the means of treating and preventing this infection. This study was conducted to represent a simple and usable animal model for C. parvum so that it can be used in the drug-related studies... |

Abstract
|
| |
Toxoplasma gondii is an intra cellular protozoan parasite which infects 30 to 60% of the world population. A wide range of toxoplasmosis conditions has been studied, but there are still unknown damages which must be explored. In the present research, the effect of this parasite on testosterone and cortisol changes in the infected men and women was examined.
A total of 180 patients (73 females and 107 males), were examined for lgG anti- Toxoplasma antibody, cortisol and testosterone in their plasma. In addition, the patients also filled in personality questionnaire DASS21 (depression, anxiety, and stress)... |

Abstract

Today mining operations in the metallurgy generate secondary products which cannot be used directly in the basic technology. The mineral industry is increasingly faced with the need to process low grade ores and waste from current mining operations. Heap bioleaching of low grade sulfide is a developing technology that has been applied to the extraction of metal from secondary sulfide minerals. The microorganisms used in the bioleaching of the low grade sulfide ores are mostly different strains of Thiobacillus... |

Abstract
|
| |
Directed evolution is an incredibly powerful tool for altering the properties of enzymes. This approach uses a "sloppy" version of PCR, in which the polymerase has a fairly high error rate to amplify the wild-type sequence. The aim of this study was to produce the Bacillus subtilis mutant lipase which can be active at low temperatures using the error-prone PCR method.
The pGEM-T vector containing B. subtilis lipase gene was transformed into the Escherichia coli DH5α. The lipase gene was mutated using the error-prone PCR technique... |

Chronic infection with hepatitis C virus (HCV) is a major cause of cirrhosis and hepato-cellular carcinoma. Since response to anti-viral therapy in sufferers depends on HCV genotypes, determination of such genotype is of great significance to the treatment. This study seeks to estimate the HCV genotype prevalence in Shiraz, southern Iran and help specify the treatment course.
A RT-PCR available kit with genotypes specific primer sets for major HCV genotypes (1a, 1b, 2 and 3a) was used. These primers amplified different parts of 5 un-translating region-core region of HCV genome... |

Naphthalene as a cyclic aromatic hydrocarbon is one of the major part of pollution in oil-contaminated environments. Methyl tert-butyl ether (MTBE), an additive to gasoline, is widely used. MTBE is highly water soluble, toxic and causes cancer. Naphthalene degraders have gene for co-oxidation of other toxic compounds therefore Naphthalene degrader could utilize and oxidize other toxic contaminant. The aim of this study is to isolate and identify bacteria that could degrade Naphthalene and MTBE as a circular and liner component respectively... |

Electroencephalogram showed diffuse dysfunction in the
brain. There was few white blood cell but normal glucose
and protein in the cerebrospinal fluid (CSF). Brain MRI
showed bilateral atrophy of cerebellum. |

The amount of nitrogen fixed by Azotobacter varied from 0.02-0.25 KgN/ha/d and has been reported to be variable with various physiological and environmental factors. The nitrogen fixation by mesophilic soil isolates and their analogue resistant mutants of Azotobacter chroococcum was compared with their thermotolerant mutants at three different temperatures (30oC, 37oC, 42oC). Mutants spontaneously resistant to methylammonium chloride were derived originally from a soil isolate of A. chroococcum. Ammonia excretion ability of different strains of A... |

Metronidazole (Mtz) resistance in Helicobacter pylori has been found to be associated with mutations in rdxA, a gene encoding an oxygen insensitive NADPH nitroreductase, and enhanced by mutations in frxA a gene encoding a NAD(P)H-flavin oxidoreductase. In this study, we examined the prevalence of rdxA deletion among local isolates of H. pylori. We tested 63 H. pylori isolates obtained from 191 patients referred to endoscopy unit of Afzalipour hospital in Kerman, Iran, during 2009 for their susceptibility to common anti-H... |
