the ingested nitrates sourced from tap water, food, chemicals and pharmaceuticals areconverted to nitrites in the body surfaces by bacteria and then, the nitrite ions can lead thestructural changing in hemoglobin. in the present work, aggregation of the purified hemoglobinin adult (hba) and in fetus or newborn (hbf) in the presence of nitrite ions were studied.hemoglobin aggregation was perform...

Charge particle therapy with 12 C ions has the advantage of an enhancement in physical dose distribution due to the Bragg Peak (BP) related to higher Relative Biological Effectiveness (RBE) with respect to X-ray radiotherapy and proton therapy (2.5 for 12 C ions and 1.1 for protons) [1], [2]. The RBE of a 12 C therapeutic beam changes dramatically with depth, especially towards the end of the S...

Measured cross sections after heavy ion bombardment, for both single and double strand breaks of SV-40 virus in EO buffer (which emphasizes indirect effects), are consistent with the theory of Butts and Katz for 1-hit detectors.

background and aims: sea buckthorn (hippophae rhamnoides l.) is a deciduous plant and has highly variable type and size, from small shrubs to medium-sized trees, traditionally growing in tibet and currently all over the world especially in europe and asia. this study aimed to overview some of therapeutic and non-therapeutic properties of sbt and its potential benefits and side effects in order ...

This article provides an overview on the application of metallic ions in the fields of regenerative medicine and tissue engineering, focusing on their therapeutic applications and the need to design strategies for controlling the release of loaded ions from biomaterial scaffolds. A detailed summary of relevant metallic ions with potential use in tissue engineering approaches is presented. Remai...

this study examines the effects of change in the concentrations of monovalent and divalent ions in the polymer-contained surfactant solution on the macroscopic behavior of viscous-modified surfactant waterflooding in heavy oil reservoirs. salts that are used in this set of floods were sodium chloride, magnesium chloride, and calcium chloride. the results indicate that four different ranges of s...

118 dentistry students were studied to show the possible correlation between ph, concentration of ca2+, p3+, na+, and k+ of saliva and decay, missing, and filling tooth (dmft index). candidates were between 20 and 30 years old and had no background systemic disorders; medial and dental histories, age, sex, and dmft index were recorded in a questionnaire organized for this purpose. saliva sample...

conclusions it was concluded that the efficacy of tramadol and fluoxetine in males with premature ejaculation are the same and both are effective. both of these drugs are safe to treat premature ejaculation. results thirty-six subjects with the mean age of 44 ± 19.3 years underwent analysis. eighteen subjects were treated by fluoxetine and 18 by tramadol. the efficacy of treatment in the two gr...
