normal 0 false false false en-us x-none ar-sa microsoftinternetexplorer4 background: definitions of chronic kidney disease (ckd) in many catheterization laboratories have relied on the serum creatinine (scr) rather than glomerular filtration rate (gfr). regarding that ckd is the primary predisposing factor for contrast induced nephropathy (cin), we compared the sensitivity of calculated gfr by ...
The Extended Hildebrand Solubility Parameter Approach (EHSA) is used to estimate the solubility of satranidazole in binary solvent systems. The solubility of satranidazole in various water-PEG 400 mixtures was analyzed in terms of solute-solvent interactions using a modified version of Hildebrand-Scatchard treatment for regular solutions. The solubility equation employs term interaction ...
The rivers sediment load is determined using hydrologic methods. In the statistical methods, by measuring the rivers discharge and suspended sediment load in a long-term period, the relationships between the suspended sediment load and discharge is obtained. The aim of this study is to compare different estimation methods of suspended load and select the most appropriate relationship for the pr...
Advances in DNA sequencing technology have caused generation of the vast amount of new sequence data. It is essential to understand the functions, features, and structures of every newly sequenced data. Analyzing sequence data by different methods could provide important information about the sequence data. One of the essential tasks for genome annotation is gene prediction that can help to und...
Potassium is one of nutritional element that has an important effect on the quantity and quality of rice plant. Knowledge about the K critical level and plant response to different application rate of K, can effectively help with the proper use of this element. Therefore, in this study potassium (K) critical level for rice (Khazar variety) and prediction equation for grain yield were determined...
BACKGROUND Serum creatinine (S-Cr)-based prediction equations are commonly used for estimating glomerular filtration rate (GFR). However, S-Cr concentration is also affected by other factors such as tubular secretion, muscle mass, diet, gender and age. Serum cystatin C (S-Cys C)-based prediction equations have been proposed as an improved potential alternative as S-Cys C levels are not influenc...
BACKGROUND Serum creatinine concentration is widely used as an index of renal function, but this concentration is affected by factors other than glomerular filtration rate (GFR). OBJECTIVE To develop an equation to predict GFR from serum creatinine concentration and other factors. DESIGN Cross-sectional study of GFR, creatinine clearance, serum creatinine concentration, and demographic and ...
BACKGROUND & OBJECTIVE The applicability of Caucasian prediction equations in interpreting spirometry data in Indian patients has not been studied. The present study was undertaken to see if Caucasian and north Indian prediction equations can be used interchangeably while interpreting routine spirometric data. METHODS Forced vital capacity (FVC), forced expiratory volume in first second (FEV(...
Skinfold thickness (SF) measurements are commonly used for the indirect assessment of body composition. It is necessary to know how large the bias is when using Caucasian SF-based prediction equations Africans, as no specific equations exist. Our first aim was to test the validity of the equation of Durnin & Womersley for predicting body density from SF in Africans. The second aim was to determ...
