Abstract
|
| |
Children with urinary tract abnormalities are susceptible to bacterial urinary infection (UTI); fungal infection, although rare, is reported to be increasing. Here, we describe a seven month-old male infant with posterior urethral valves who had developed both bacterial and fungal (Candidal) urinary tract infections. Direct and culture examinations of urine sample confirmed urinary tract candidiasis. Urine culture yielded more than 3×104 Candida albicans. Fluconazole started in the dose of 4mg/kg/day, single dose daily (25mg or 1/2 tablet) for two weeks... |

Klebsiella pneumoniae is an opportunistic pathogen most frequently associated with extended spectrum β-lactamase (ESBL) production. These organisms are usually resistant to most antibiotics and pose a serious threat for health care associated infections. Plant essential oils rich in carvacrol and thymol have gained importance for their antimicrobial activity. We determined the composition of Zataria multiflora essential oil of the Jandagh area in Iran and measured its activity against ESBL producing urinary isolates of K... |

The potential risk of application of high dosage of traditional medicinal plants has not been fully understood. Appropriate microbial biosensors have been constructed for monitoring the toxicity of many harmful chemical compounds. The aim of this research was to see how effective are the different concentration of two medicinal plants extracts (Crocus sativus (saffron) and Cannabis sativa) on a bioluminescent marker system indicating their side effects. The stability and light intensity of Escherichia coli SM10λpir were previously characterized and confirmed... |

Tannin acyl hydrolase (tannase E.C. 3.1.1.20), commonly referred to as tannase, hydrolyses the ester bond (galloyl ester of an alcohol moiety) and the depside bond (galloyl ester of gallic acid) in substrates such as tannic acid, methylgallate and m-digallic acid. This is an inducible enzyme produced by various filamentous fungi. The aim of present research was to isolate, clone and sequence partial gene of tannase from Aspergillus niger. Aspergillus niger was grown in a selective medium and then genomic DNA was directly extracted from fungal mycelium... |

Oropharyngeal candidiasis is a relatively common mycotic infection in cancer patients. In vitro susceptibility of oropharyngeal Candida isolates can be useful in selecting the appropriate treatment for the best therapeutic outcome. The aim of this study was to evaluate the in vitro antifungal activity of Candida species against antifungal agents. In vitro activities of four antifungals were detected in 69 Candida isolates recovered from cancer patients in four university hospitals using the microdilution method described in the CLSI M27-A3 guideline... |

The uses of traditional medicinal plants for primary health care have steadily increased worldwide in recent years. Triphala has been used in the traditional medicine for the treatment of variety of diseases and therefore it becomes immense to study the phytochemical compounds and antibacterial activities. Aqueous and alcoholic extracts of both Triphala and its individual components were used, to evaluate antimicrobial activity. Phytochemical (phenolic, flavonoid and carotenoid) and antibacterial activities of aqueous ethanolic extracts of Triphala and its individual components (Terminalia chebula, T... |

Hepatitis D Virus (HDV) infection is a widespread disease that has affected a large number of population with hepatitis B Virus (HBV) infection in Iran. Disease is considered to be a major public health problem in Iran. Delta hepatitis is the least common form of chronic viral hepatitis and is the form most likely to lead to cirrhosis. Delta hepatitis is serologically complex, so effective therapy is difficult. The diagnosis is made on the basis of the presence of antibodies against HDV (anti-HDV) and hepatitis B surface antigen (HBsAg) in the serum of a patient with chronic liver disease... |

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... |

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)... |

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... |
