Background: Various compounds of plant origin have been widely investigated since ancient times for their possible immunomodulatory properties as well as for the treatment of a wide range of diseases. Objective: To study the immunomodulatory functions of the aqueous extract of the seeds of Abrus precatorius commonly known as Indian liquorice (Fabaceae), a medicinal plant native to central India...
The aerosol penetration efficiency and quality factor for three Chemical Biological Radiological protective fabrics were evaluated using a particle counting technique. Both parameters characterise aerosol penetration through tested material; the latter accounts for the effect of fabrics air permeability. The overall and size dependent penetrations of 0.03–3 μm sized Sodium Chloride (NaCl) and D...
background : limited studies are available on the calculation of radiation exposure and its associated risks for people in contact with patients who have been treated with permanent prostate brachytherapy. in this study the changes in the radiation exposure were calculated in different stages of the bladder fullness in prostate seed brachytherapy. methods :magnetic resonance images of three pat...
Introduction: The dosimetry of the brachytherapy sources is performed in the water source medium according to protocol TG-43U1. To achieve a resonable results on treatment, the use of the water material for all body tissues can be one of the faulty sources in delivering the correct dose to the tumor. Thus, we have focused on the dosimetry parameters in fat density 0.95 gr/cm3 and the muscle wit...
In this paper, the ratio of adsorbed dose to the tissues of muscle, blood and bone to water for medical accelerators of Electa 25MV and Siemens 6MV is calculated using an analytical method based on cavity theory and Monte Carlo simulation. To confirm the validation of these methods, the ratio of absorbed dose to air to water was determined experimentally for radiation field of 60Co in Secondary...
Photoacoustic spectroscopy measurements of flame-generated soot aerosol coated with small amounts of water yielded absorption enhancements that were dependent on the laser used: quasi-continuous wave (Q-CW, ≈ 650 ps pulse duration and 78 MHz repetition rate) versus continuous wave (CW). Water coating thickness was controlled by exposing the aerosol to a set relative humidity (RH). At ≈ 85 % RH,...
OBJECTIVE The purpose of this study was to evaluate the efficacy of high dose of metronidazole in the treatment of Helicobacter pylori (H. pylori) infection. METHODS Studies were identified from databases (Pubmed, Embase, Cochrane Library, ClinicalTrials.gov) searched from January 1990 to September 2017 using a battery of keywords. We included randomized controlled trials (RCTs) of H. pylori ...
