background: platelet preparations have been used for a wide variety of clinical applications such as hemorrhage, tissue engineering and cellular therapy. platelet concentrates can be prepared by the apheresis method or from the whole blood using the buffy-coat or platelet-rich plasma methods. the purpose of this study was to compare four variations of platelet-rich plasma method based on double...

objective: the current study was undertaken to examine the bactericide effects of atmospheric plasma produced by flat and comb electrodes on e.coli. materials and methods: dc (20 w) and ac (500 w) power supplies, flat and comb electrodes, insulator and oxygen gas were used to produce atmospheric plasma. bactericide effects of the atmospheric plasma were studied on e.coli on sterilized plate pla...

objective to determine the changes in thyroid function tests in children who underwent antiepileptic therapy in shahid beheshti hospital, kashan, in 2008. materials & methods this analytical-observational study was carried out in a cohort fashion without an external control group (self controlled) on 45 children with new onset epilepsy who had not been previously treated with antiepileptic medi...

high-performance liquid chromatography (hplc) methods employing ultraviolet (uv) detector are not sufficiently sensitive to measure the low plasma concentrations following single oral dose of imipramine. therefore, in the present study a simple, rapid and yet sensitive hplc method with uv detection was developed and validated for quantitation of imipramine in human plasma samples. an efficient ...

low plasma level of vitamin d is linked to the increased risk of cardiovascular diseases such as hypertension, diabetes, dyslipidemia and peripheral vascular diseases. vitamin d deficiency is a worldwide problem that involves iranian population. to the best of our knowledge, this was the first investigation on venous thromboembolism (vte) subjects that assessed the correlation of vitamin d leve...

more than 30 mineral elements have been found with different key functions in helping plants and animals to survive and live healthy. as a direct result, they have always attracted the attention of scientists. the quest is to find some efficient analytical and quantitative procedures in this study to determine some mineral and trace elements of iranian crocus sativus l. corms. several studies h...

Background: Due to multiple roles of albumin in the body, injection of its medicinal product as one of the therapeutic or management strategies under conditions such as severe bleeding, burns, liver failure, and neonatal hemolytic diseases is on the physicians' agenda. Considering that albumin is the most abundant plasma protein, designing an appropriate method to purify it is highly important....

During deposition, modification, and etching of thin films nanomaterials in reactive plasmas, many active species can interact with the sample simultaneously. This includes neutrals formed by fragmentation feed gas, positive ions, electrons generated electron-impact ionization gas fragments, excited states (in particular, long-lived metastable species), photons produced spontaneous de-excitatio...
