ABSTRACT Background: accurate methods of radiation therapy dose calculation. There are different Monte Carlo codesfor simulation of photons, electrons and the coupled transport of electrons and photons. MCNPis a general purpose Monte Carlo code that can be used for electron, photon and coupledphoton-electron transport.Monte Carlo simulation of radiation transport is considered to be one of the ...

Quality control to obtain composite laminates is frequently applied synthetic fibers/epoxy prepregs. The gel time test, resin, volatiles and fiber content, drape measurement tack tests together with water absorption capacity are methods currently employed. However, for natural fibers prepregs there a gap in the literature, which makes their application difficult. Thus this work will investigate...

Objective(s): To investigate and compare quantitative accuracy of kidney absorbed dose measures made from both 2D and 3D imaging in patients receiving 177LuDOTATATE (Lutate) for treatment of neuroendocrine tumours (NETs). Methods: Patients receiving Lutate therapy underwent both whole body planar imaging and SPECT/CT imaging over the kidneys at time points 0.5, 4, 24, and 96-120 hours after inj...

Intestinal epithelial cells absorb ingested neutral lipids, apparently as water-soluble micelles of bile salts, monoglycerides, and/or fatty acids (3, 7). Electron microscopy of intestinal cells fixed in osmium tetroxide reveals some of the absorbed lipid as electron-opaque droplets in the apical cytoplasm distal to the microvilli and subjacent terminal web (10). Experiments by Strauss and Ito ...

Silk fabrics were modified by a treatment of silver nitrate solution (AgNO3) and polyvinylpyrrolidone (PVP) as a stabilizer then exposure to γ-irradiation to create antibacterial properties. Effects of the absorbed dose on treated fabrics were investigated. The scanning electron microscopy (SEM) and X-ray diffraction (XRD) patterns were used to confirm the presence of silver nanoparticles (AgNP...

4.1 Absorption, distribution, metabolism and excretion The disposition of various formulations of oral contraceptives used in humans differs. In general, both the oestrogenic and progestogenic compounds in combined oral contraceptives are absorbed by the gut and metabolized largely in the liver. A fraction of the absorbed dose of ethinyloestradiol and several progestogens is excreted in the bil...

capacity was saturated by an acute intravenous infusion of iron, deposited a large fraction of intestinally absorbed iron in the liver during the first pass of portal venous blood through this organ.1 Subsequently, Wheby and Umpiere demonstrated similar results in normal human subjects given sufficient iron to acutely saturate their plasma iron-binding capacity.2 Our results in patients with sp...

A correlation has been established between the absorbed fraction of training-set molecules after oral administration in humans and the Quantum Mechanical Polar Surface Area (QMPSA). This correlation holds for the QMPSA calculated with structures where carboxyl groups are deprotonated. The correlation of the absorbed fraction and the QMPSA calculated on the neutral gas phase optimized structures...
