BACKGROUND AND PURPOSE Osmotic agents such as glycerol are used to treat brain edema in stroke patients. We investigated the pharmacokinetics of glycerol in brain tissue by cerebral microdialysis. METHODS Patients experiencing large middle cerebral artery infarction were included in this prospective study. The following variables were assessed before and every 10 minutes until 80 minutes afte...
abstract cooperative learning refers to small groups of learners working together as a team to solve a problem, complete a task, or accomplish a common goal. in a cooperative environment one’s success is directly related to the success of other members because the focus on the individual shifts towards the group. to test the effectiveness of the method, using jigsaw technique, a study was cond...
Background . Euphorbia fischeriana Steudel is used in traditional and herbal medicine Russia China. Its roots contain 241 chemical components, but there not enough knowledge about the plant’s elemental composition. Concentrations of elements plants have an impact effectiveness medical products. Materials methods The research was conducted Transbaikal region. Plants were analyzed using ICP-MS El...
Phosphorus, sulfur, silicon and metal concentrations (Al, Cu and Zn) were determined in human brain proteins by laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS) after separation of protein mixtures by two dimensional (2-D) gel electrophoresis. The analysis of phosphorus, silicon and metals in single protein spots in the gel was performed with an optimized microanalytical ...
abstract part one: the electrode oxidation potentials of a series of eighteen n-hydroxy compounds in aqueous solution were calculated based on a proper thermodynamic cycle. the dft method at the level of b3lyp-6-31g(d,p) was used to calculate the gas-phase free energy differences ,and the polarizable continuum model (pcm) was applied to describe the solvent and its interaction with n-hydroxy ...
nowadays, the development of anti cancer drugs is an important subject in pharmacology. bisphosphonates (b.p) are a great choice for design and production of the types of drugs which not only could perform as anti cancer agents but also could inhibit the function of acetyl cholinesterase (ache). ache hydrolyzes the acetylcholine (which is a neurotransmitter in nervous system) using the oh in i...
this study was an attempt to investigate the effect of using c-test passages on the reading comprehension and incidental vocabulary learning of iranian intermediate efl learners. the participants were 60 male efl learners at kish mehr institute in garmsar. in fact, there were two groups, an experimental group and a comparison group with 30 students in each. the participants were pretested throu...
Intake of specially processed cereal (SPC) stimulates endogenous antisecretory factor (AF) activity, and SPC intake has proven to be beneficial for a number of clinical conditions. The aim of the present study was to investigate the dosage relationship between SPC intake and plasma AF activity and to further correlate achieved AF levels to a biological effect. SPC was fed to rats in concentrati...
A quantitative energy dispersive X-ray fluorescence (EDXRF) spectrometry method was developed for determining the concentration of palladium (Pd) applied to tobacco cut filler. Control and standards were created in-house with different levels of Pd concentration. After application of the Pd in a salt solution, the tobacco had an average oven volatiles (OV) value of 27.6%. Three aliquots were an...
Laser ablation-inductively coupled plasma-mass spectrometry (LA-ICP-MS) was used to study the spatially-resolved distribution of ruthenium and platinum in viscera (liver, kidney, spleen, and muscle) originating from mice treated with the investigational ruthenium-based antitumor compound KP1339 or cisplatin, a potent, but nephrotoxic clinically-approved platinum-based anticancer drug. Method de...
