Background: The basic challenge with computed radiography (CR) systems is the large dynamic range which provides an opportunity for radiographers to gradually increase exposure factors and still produce good image quality, a practice that can lead to dose creep. Materials and Methods: The aim of this study was to establish  the entrance skin dose (ESD) values for nine selected examinations in t...

Curcumin (CUR) is a hydrophobic molecule and beneficial antioxidant with known anticancer property. The bioavailability of curcumin is low because of its hydrophobic structure. Mesoporous silica nanoparticles (MSN) loaded by CUR were used as nanocarriers for sustained release of CUR in four different media such as simulated gastric,intestinal, colon and body fluids (SGF, SIF, SCF, and SBF, ...

materials and methods a total of 228 fecal samples were collected from residents of rural areas of hamadan, west of iran. each fecal sample was divided into two parts, one kept frozen at -20˚c for ag-capture elisa and the other in 10% formalin for the ap staining method. cryptosporidium ag-detection elisa procedure was performed according to the manual of the manufacturer. the preserved samples...

Objective: Angina pectoris (AP), affecting over 523 million people, can be alleviated by corydalis rhizome (CR), usually combined with chuanxiong (CXR), angelica dahuricae radix (ADR), or astragali (AR) to enhance the effect. This study aims distinguish different mechanisms among 3 drug pairs treat AP. Methods: The pair-disease intersection targets, compound protein–protein interaction (PPI), a...

background: this study focused on isolation and identification of a phenanthrene (phe) degrader bacterium and optimization of environmental conditions for phe degradation. materials and methods: enrichment technique was used for isolation and the most effective isolate, named ap, selected based on its phe biodegradation abilities. the isolate was identified using morphological and biochemical t...
