The aim of this study was to evaluate the safety effects of prebiotic isomalto-oligosaccharid on the damage of liver and gill tissues in common carp exposed to lethal concentrations of toxin butachlor. A total of 120 specimens of common carp with an average weight of 6.13±0.31 g were kept. Water physicochemical parameters were measured during the experiment. LC50 96h for toxin butachlor was ob...
widespread use of nanosilver can be led the contamination of aquatic environment and impact on living organisms such as fishes. we investigated histopathological changes in the gills tissue of caspian roach fingerlings after two weeks exposure to sublethal concentrations of nanosilver. following one and two weeks exposure, necrosis, shortening of secondary lamellae, edema, destruction of epithe...
attempts have been made to study the thermodynamic behavior of 1,3 butadiene purification columns with the aim of retrofitting those columns to more energy efficient separation schemes. 1,3 butadiene is purified in two columns in series through being separated from methyl acetylene and 1,2 butadiene in the first and second column respectively. comparisons have been made among different therm...
We evaluate osmotic and chloride (Cl(-)) regulatory capability in the diadromous shrimp Macrobrachium amazonicum, and the accompanying alterations in hemolymph osmolality and [Cl(-)], gill Na(+)/K(+)-ATPase activity, and expression of gill Na(+)/K(+)-ATPase α-subunit and V-ATPase B subunit mRNA during salinity (S) acclimation. We also characterize V-ATPase kinetics and the organization of trans...
OBJECTIVE To assess azithromycin levels in human serum, aqueous humor, tear fluid, and conjunctival tissue specimens after administration of a single 1-g oral dose of azithromycin. METHODS Sixty patients undergoing cataract surgery were included in this analysis. Serum, aqueous, and tear specimens were collected 3, 6, and 12 hours and 1, 2, 3, and 4 days after azithromycin administration. Con...
abstract ion selective electrodes (ises) are electrochemical sensors that respond selectivity to the activity of ionic species. an ion-selective electrode is an electrochemical device that uses a thin selective membrane or film as the recognition element, and is an electrochemical half-cell equivalent to other half-cells of the zeroth (inert metal in a redox electrolyte). in common methods o...
The presence of contaminants in aquatic bodies causes stress responses in aquatic animals, especially fish, which ultimately affects the physiological condition of fish and reduces their immune function, so the use of immune stimulants such as prebiotics is essential. The aim of this study was to investigate the effect of different levels of pleurotus ostreatus on the histological characteristi...
background and objectives:rapid processing of histopathological specimens and decreased turnaround time is important to fulfill the needs of clinicians treating sick patients, so the present study was conducted to compare the time taken and quality of sections in processing of prostatic tissue by rapid microwave and conventional techniques using morphometry.methods: four to five mm thick paired...
Introduction: Resistin is a peptide hormone, secreted by adipose tissue. Increased secretion of resistin results in insulin resistance and metabolic syndrome. The aim of this study was to determine the effect of hydro-alcoholic spinach (Spinacia oleraceae L.) extract on the expression of resistin mRNA in the visceral adipose tissue of rats exposed to chronic immobilization stress. Materials and...
one of the most important goals for increasing recognition and treatment revenue is transmitting vital data to medical care team, more quickly. nowadays, use of new technologies for transmitting data will deploy more and more daily. in this article, for transmitting electrocardiogram, first we code the signal into a suite of codes, then we will use bluetooth technology to transmit data from off...
