background and objectives: sodium nitrite and potassium nitrite have been traditionally used for inhibition of clostridium botulinum and also as an agent to stabilize the color of meat products; however, usage of these additives at high levels could lead to toxicity and cancer originating from the formation of nitrosamines. nowadays, application of natural preservatives in order to reduce the n...

in this study prevalence of parasites in 118 samples (62 foxes and 56 jackals) was investigated in ilam province of iran, in 2010-2013, situated in the western part of the national capital of iran. the nematodes which were cleared in lactophenol, cestodes and acanthocephalans were stained using acetocarmine and haematoxylen, respectively for identification of the parasite species. cryptosporidi...

background and purpose:organic dyes with a complex structure are often toxic, carcinogenic, mutagenic, non-biodegradation and stable in the environment and if released to the environment without treatment can endanger the environment and human health. the aim was to evaluate the performance nanoscalezero-valent iron (nzvi) in the removal of dye acid red 18 (ar18) from aqueous solutions. materia...

backgroud and purpose: dye is one of the problems of industrial effluent such as textile industries. the dyes can be removed by various methods. therefore, the aim of this study was the evaluation of adsorption rate of reactive red 198 from aqueous solution by activated red mud. materials and methods: this research was a lab study. activated red mud was used as an adsorbent to remove reactive r...

in this study, surface water samples were collected monthly from five stations inclduing nayband bay, assaloye, dayer, kabgan and bushehr from december 2012 to june 2013. sampling stations were chosen according to data being collected during algal bloom caused by cochlodinium polykrikoides in 2008. a total of 45 genera of phytoplankton belongs to four classes were totally identified accounting ...

the pharmacokinetics of recombinant human erythropoietin (rhuepo) administered intravenously has been investigated in a group of five patients with chronic renal failure who were dialysis-dependent. the half-life of circulating erythropoietin decreased from 7.9±oa hr (mean ±so) at the beginning of treatment to 6.2±o.6 hr after 6 weeks and 5a±o.9 hr after 4 months of treatment. in spite of the s...

the interaction between isatin-β-thiosemicarbazone (ibt) and calf thymus dna (ct-dna) was investigated in physiological buffer (ph 7.4) using neutral red (nr) dye as a spectral probe by uv–vis absorption and fluorescence spectroscopy, as well as viscosity measurements. the ibt is stabilized by intercalation in the dna ( k [ibt –dna] =1.03×105 m−1), and displaces the nr dye from the nr–dna comple...

in this work, the adsorption of the anionic dye, congo red (cr), from aqueous solution by using tea waste (tw) has been carried out at 30 °c. the equilibrium sorption isotherms and kinetics were investigated. the equilibrium adsorption was studied by the langmuir and freundlich models of adsorption. the experimental results manifested that the langmuir isotherm was the best model for the adsorp...

This syndrome is a shock-like hyper metabolic myopathy triggered in susceptible animals by stress. Capture myopathy (C.M.) is a commonly occurring condition in mammals following trapping and transportation. In this case 12 to 24 hours after transportation of red deer (Cevus elaphus) and wild goats (Capra ibex) clinical signs such as: muscular tremor, ataxia, recumbency, hyperthermia, tachyca...
