Determination of the radionuclide iodine 129 using ICP-MS has been improved by the use of an Octopole Reaction System (ORS) ICP-MS, operated in oxygen cell mode. Oxygen reaction gas removes the background signal at m/z 129, which is due to the presence of Xe as an impurity in the Ar plasma gas and to the polyatomic ion IH2. NIST SRM standards with different 129I/127I ratios and at multiple conc...

Investigation of the dichloromethane extracts from herbal and root parts of Mercurialis perennis L. afforded a mixture of 11 homologous n-alkylresorcinols (ARs) with saturated odd-numbered alkyl side chains (C15:0-C27:0). In addition to three predominant ARs (C19:0, C21:0 and C23:0), a number of minor ARs were identified by use of LC-MS/MS and GC-MS techniques. Among the compounds detected, fou...

normal 0 false false false en-us x-none ar-sa background: the relation between vitamin d deficiency with depressive and fatigue symptoms in both multiple sclerosis (ms) patients and healthy population have been reported. to represent our regional achievement in this field we investigated the relation between vitamin d status with fatigue and depressive symptoms in ms patients. materials and met...

Endocrine active substances (EAS) show structural similarities to natural hormones and are suspected to affect the human endocrine system by inducing hormone dependent effects. Recent studies with in vitro tests suggest that EAS can leach from packaging into food and may therefore pose a risk to human health. Sample migrates from food contact materials were tested for estrogen and androgen agon...

BACKGROUND Preoperative fasting is a requirement to be made by anesthesiologists, but they generally depend on nurses to ensure it is carried out by patients. Lack of updated knowledge among nurses may cause complications. METHOD The objective of this study was to understand the knowledge of nurses about preoperative fasting. The multi-unit study was conducted in the units of our hospitals us...

OBJECTIVE To compare the surgical accuracy of the maxillary repositioning according to the maxillary surgical movement type (SMT) in two-jaw orthognathic surgery (TJOS). MATERIALS AND METHODS The samples consisted of 52 Korean young adult patients with skeletal Class III malocclusion treated with TJOS by one surgeon. Lateral cephalograms were taken 1 month before (T0) and 1 day after surgery ...

OBJECTIVE The objective of the present study was to examine the relationship between plasma alkyresorcinol (AR) concentrations, which are biomarkers of whole-grain intake, and atherosclerotic progression over 3 years in postmenopausal women with coronary artery disease. DESIGN Plasma AR concentrations were measured by a validated GC-MS method in fasting plasma samples. Atherosclerosis progres...
