variations in arterial anatomy are less frequent, contrary to the venous system, and most of these variations affect visceral arteries. variations in the brachial artery are the most frequently reported and so far a minimum of six different patterns have been described. the most common of these patterns is the superficial brachial artery, which lies superficially to the median nerve. much less ...
Objective The lipid composition of a mammal’s spermatozoa and seminal plasma vary in both structure and function. Evidence exists to suggest that dietary supplementation with the appropriate polyunsaturated fatty acids (PUFAs) affects spermatogenesis, semen quality and sperm motility. Therefore, this study has been conducted to evaluate the correlations between serum lipid profile and histologi...
BACKGROUND Anatomical liver resections are based on some basic technical principles such as vascular control, ischemic area delineation to be resected and maximum parenchymal preservation. These aspects are achieved by the intrahepatic glissonian approach, which consists in accessing the pedicles of hepatic segments within the hepatic parenchyma. Small incisions on well-defined anatomical landm...
The literature describing scattering matrices for semianalytical methods almost exclusively contains inefficient formulations and formulations that deviate from long-standing convention in terms of how the scattering parameters are defined. This paper presents a novel and highly improved formulation of scattering matrices that is consistent with convention, more efficient to implement, and more...
The effect of ethyl alcohol ingestion on tetracycline kinetics was studied in 9 healthy male volunteers. They received, on two separate occasions, 500 mg of tetracycline tablets given with water or with an alcoholic beverage. The antibiotic was assayed in plasma, using a HPLC method. Absorption and disposition parameters were calculated according to classical pharmacokinetic techniques for one ...
We have observed in clinical practice that Native Americans require lower dosages of tacrolimus to attain similar target blood trough levels compared to whites after renal transplant. Because there are no pharmacokinetic studies of tacrolimus in this ethnic group, we investigated whether this clinical observation could be corroborated by pharmacokinetic differences between Native Americans and ...
With changing the parameters of layer winding in transformers, capacitive characteristic coefficient of winding will be changed. Since, impulse voltage distribution (IVD) along a winding is depended on this coefficient, so analyzing this coefficient is important in transformers. This paper study and analyze a transformer with layer winding and rectangular cross-section. In this study, the influ...
A simulation study of a Cu(In1 - xGax)Se2 (CIGS) thin film solar cell has been carried out with maximum efficiency of 24.27 % (Voc = 0.856 V, Jsc = 33.09 mA/cm(2) and FF = 85.73 %). This optimized efficiency is obtained by determining the optimum band gap of the absorber and varying the doping concentration of constituent layers. The Ga content denoted by x = Ga/(In + Ga) is selected as 0.35 wh...
This study was performed to estimate the mean pharmacokinetic parameters of routinely administered metoprolol in middle-aged and elderly Japanese patients. Whole blood concentration data (65 samples) at steady-state following repetitive administration to 34 patients were analyzed using a nonlinear mixed effects model. A one-compartment model was parameterized in terms of oral clearance (CL/F) a...
