In this work structural defects were created in P25-TiO2 nanoparticles by using hydrogen DC plasma treatment in different temperatures and exposure times. X-Ray diffraction measurements show that the structure of TiO2 remains unchanged after hydrogenation. Diffuse reflectance spectroscopy measurements demonstrated band gap of TiO2 was not changed considerably by the hydrogenation. However, by a...

the objective of this study was to evaluate kinetics and the residual decline of tylosin in milk and plasma of lactating najdi ewes following single intramuscular injection of tylosin at the dose of 10 mg/kg. blood and milk samples were collected from the ewes before and at different time intervals after treatment. tylosin concentrations were determined by microbiological agar plate assay using...

In this study, polyethersulfone based nanofiltration membranes were modified by air plasma generated through dielectric barrier discharge to increase the membrane hydrophilicity aiming to improve the separation and antifouling characteristics. The effect of plasma time on the physico-chemical and separation properties of membrane was investigated. The PES nanofiltration membranes were fabricate...

background and objectives: biomaterials are widely used in medical devices such as urinary catheters. one of the main problems associated with long term using of the urinary catheters is biofilm formation on their surfaces. many techniques have been presented to reduce the biofilm formation. one of the most revolutionary techniques allowing such surface fictionalization is plasma surface modific...

otostegia persica (burm.) boiss. is used for the treatment of various diseases in traditional medicine. the aim of this study was to assess the effects of hydroalcoholic extract of the aerial parts of o. persica in dexamethasone (dex) induced hypertension in male wistar rats. for induction of hypertension, dex at 30 µg/kg/day was administered subcutaneously for 14 days. in a prevention study, a...

background: plantar fasciitis (pf) is a common foot complaint, affects both active sportsmen and physically inactive middle age group. it is believed that pf results from degenerative changes rather than inflammation. platelet?rich plasma (prp) therapy has been introduced as an alternative therapy for pf. this study is aimed to systematically review to the effectiveness and relevant factors of ...

ferula foetida (bunge) regel. is one of the most widespread and important ferula species with nutritional and medicinal applications. some phytochemicals with helpful cardiovascular effects have been isolated from ferula species. the present study was designed to evaluate the effects of hydroalcoholic extract of the stems of f. foetida in dexamethasone (dex)-induced hypertension in rats. hypert...

Background: The aim of this study was to investigate the effects of administration of a GnRH analogue to cows with ovarian follicular cysts on plasma renin concentrations and ovarian vascularization. Materials and Methods: This study was performed with 60 Friesian cows, which were diagnosed with follicular cysts, and randomly allocated into two groups: group A (treatment; n = 30) received 2 ml ...
