The activity of oxidative and hydrolytic enzymes of the edible and medicinal white rot fungi Coprinus cinereus (Schaeff.) Gray mushroom was observed during mycelia growth and fruiting body development in solid substrate fermentation using sisal waste fractions amended with cow dung manure as supplement. Laccase had the highest titre value among the five detected enzymes. Its activity was higher...

Pulp and paper mill effluent is posing a serious threat to the water and soil components of the environment due to its brown colour and high level of toxicity. Fungal treatment is one of the efficient methods for treating pulp and paper mill effluent. In the present study, for the treatment of from pulp and paper industry, nine efficient fungal strains including Phanerochaete chrysosporium, ded...

Four sheep were fed an alfalfa hay diet. Rumen content samples were collected three hours after feeding in order to total microorganism population (TP), solid attached population (SAP) and solid attached firmly population (SAFP). Fibrolytic specific activities (xylanase, CMCase and beta-glycosidases) were estimated by the amount of reducing sugars or p-nitrophenol released from the appropriate ...

Twenty-one moderately halotolerant fungi have been isolated from sample ashes collected from Sebkha El Melah, a Saharan salt flat located in southern Tunisia. Based on morphology and sequence inference from the internal transcribed spacer regions, 28S rRNA gene and other specific genes such as β-tubulin, actin, calmodulin, and glyceraldehyde-3-phosphate dehydrogenase, the isolates were found to...

background: bradford protein assay is popular due to its ease of performance and relative sensitivity. many researchers and laboratories in iran use standard assay of bradford by cuvette. no commercial kit was available for bradford microplate assay in iran. meanwhile, imported bradford commercial kits are very expensive and have a long delivery time in iran. till now no study or document on br...

background: early pleural tuberculosis (tb) diagnosis is particularly difficult. the aim of this study was to investigate the diagnostic accuracy of the xpert mtb/rif (xpert) (cepheid, sunnyvale, ca) assay using pleural biopsy and pleural fluid specimens in patients with suspected pleural tb but who had a negative sputum acid-fast bacilli (afb) smear. materials and methods: in this study, 134 s...

abstractbackground: radioprotective effects of famotidine, an antagonist of h2 receptor clinically used for peptic ulcer treatment, was previously shown on radiation-induced micronuclei and chromosomal aberration in human peripheral blood lymphocytes and mouse bone marrow cells. this study was conducted to investigate radioprotective property of famotidine against radiation induced apoptosis in...

introduction: this study aimed to compare the cytotoxicity of mta fillapex, ah-26 and apatite root canal sealers at different times after mixing. methods and materials: in this in vitro study, mta fillapex, ah-26 and apatite root canal sealer were spilled uniformly by 40 µm mesh in a 96-well plate. then, human fetal foreskin fibroblast cell line (hfff2) were added to each sealer cell culture me...
