introduction & objective: adequate and proper hydration during surgery is one of the duties of anesthesiologist. based on the different effects of dextrose–containing fluids and dextrose-free fluids on the level of blood sugar, we decided to evaluate the effects of these fluids on the blood sugar level after short-term surgeries. materials & methods: one hundred patients who were scheduled for ...

background and objective: bacterial meningitis is an important cause of mortality and long-term neural morbidity. immediate diagnosis and treatment are necessary in appropriate time. this study was designed in afzalipour hospital in kerman to evaluate meningitis causes, frequency and csf laboratory changes. patients and methods: in this retrograde descriptive study from september 2003 to septem...

Nonequilibrium, NVT, molecular dynamics (NEMD) simulations were used to obtain the shear viscosity, η, of isoamyl alcohol, n-butyl acetate, and their binary mixtures at 35°C and 0.1 MPa. The fluids were modeled using rigid bonds, rigid bond angles, appropriate torsional potentials, pairwiseadditive Lennard-Jones dispersion interactions between united-atom sites, and partial point charges locate...

The purpose of the study reported here was to develop a method for the determination of lipid classes in intestinal fluids, including bile acids (BAs). A solid-phase extraction (SPE) method using C18 and silica columns for the separation of BAs, phospholipids (PLs), and neutral lipids (NLs), including free fatty acids, has been developed and validated. Fed-state small intestinal fluid collected...

Reactions in scCO2 are frequently limited by the low polarity of the solvent. This may result in low solute/ product solubility or low catalyst activity. The use of more polar sc fluids such as difluoromethane (HFC 32) can circumvent many of these issues and facilitate reactions that are not possible in CO2. We demonstrate the use of HFC 32 for three types of reaction; an esterification reactio...

In this work, we present the state of the art in the use of theory (first principles, molecular dynamics, and statistical methods) for interpreting and understanding the infrared (vibrational) absorption and Raman scattering spectra. It is discussed how they can be used in combination with purely experimental studies to generate infrared and Raman images of biomolecules in biologically relevant...

We have fabricated a class of colloidal electrorheological (ER) fluids, in which suspended TiO2 particles were synthesized by a sol-gel method and modified by 1,4-butyrolactone molecules with a permanent molecular dipole moment of 4.524 D. Compared with pure TiO2 ER fluids, the quasi-static yield stress of the polarmolecules-modified ER fluid is enhanced as high as 48.1 kPa when subjected to an...

Phylogenetically diverse polar and subpolar marine teleost fishes have evolved antifreeze proteins (AFPs) or antifreeze glycoproteins (AFGPs) to avoid inoculative freezing by internalized ice. For over three decades since the first fish antifreeze (AF) protein was discovered, many studies of teleost freezing avoidance showed hepatic AF synthesis and distribution within the circulation as pivota...

Since twelve years the Chromatomembrane Cell has been proposed as a new and versatile device for extraxtion procedures in the flow based analysis. In the meantime a remarkable number of papers was submitted dealing with applications of the novel method to all the conceivable varieties of flow injection and sequential injection analysis. The device supports important analytical procedures such a...
