PURPOSE To evaluate renal function 1 year after radical nephrectomy (RN) for renal cell carcinoma, the preoperative predictors of postnephrectomy renal function were investigated by sex, and equations to predict the estimated glomerular filtration rate (eGFR) 1 year after RN were developed. MATERIALS AND METHODS A total of 525 patients who underwent RN between May 2007 and August 2011 at Toho...

To the memory of Charles C. Conley We generalize Conley's fundamental theorem of dynamical systems in Conley index theory. We also conclude the existence of a regular index filtration for every Morse decomposition. 1. Introduction. Conley is mostly known for his fundamental theorem of dynami-cal systems and his homotopy index theory [1]. In the former, he proved that every continuous flow on a ...

It is well known that uremia causes an increase in the serum anion gap (AG); however, whether changes in the AG occur earlier in the course of chronic kidney disease is not known. Here we investigated whether different measures of the AG, as a marker of kidney function, are associated with mortality. To do this, we analyzed the available laboratory data of 11,957 adults in the National Health a...

The combined influence of both melt filtration and cooling rate on the microstructure features and mechanical properties of A356 cast alloy was studied. A step casting model with five different thicknesses was used to obtain different cooling rates. The effect of melt filtration was studied by using of 10 and 20 ppi ceramic foam filters in the runner. Results showed that secondary dendrite arm ...

The present study aimed to evaluate the health risk of heavy metals (iron, zinc, cadmium, arsenic, nickel, lead, and mercury), benzene, toluene, ethylbenzene and xylene (BTEX), and polycyclic aromatic hydrocarbons (PAHs) in the workplace in a secondary oil re-refining factory. In this descriptive, cross-sectional study, samples were collected and analyzed using the NIOSH 1501 method at eight sa...

Introduction: We aimed to evaluate the intralobar renal arteries indexes using the Doppler ultrasonography indexes, which have become the established method of kidney monitoring, in living unrelated kidney donors during the postnephrectomy period. Materials and Methods: In this prospective study, we evaluated and followed up 34 living unrelated kidney donors. The Doppler ultrasonography indexes...

OBJECTIVE Prehypertension is associated with cardiovascular disease (CVD). There is no study to examine the incidence and risk factors of prehypertension in a sex stratified setting. The aim of this study was to examine the effect modification of sex for different risk factors which predicts the progression from normotension to prehypertension in a Middle East population-based cohort, during a ...

BACKGROUND A dramatic increase in the "early start" of dialysis with an estimated glomerular filtration rate (eGFR) at least 10 mL/min/1.73 m(2) has occurred in the United States since at least 1996. Several recent studies have reported a comorbidity-adjusted survival disadvantage of early start of dialysis. The current study examines a relatively "healthy" dialysis cohort to minimize confoundi...

BACKGROUND Although several cross-sectional and intervention studies showed that sodium intake or excretion was associated with blood pressure levels, no prospective study has examined the long-term association between sodium excretion in spot urine and blood pressure changes. METHODS We conducted a prospective study of 889 normotensive subjects (295 men and 594 women, mean age 57.3 years) wh...

Abstract: The Second Songhua River is the biggest river system in Jilin Province, China. In recent years, the rapid economic development in this area has increased the prominence of water resources and water-related environmental problems; these include surface water pollution and the overexploitation of groundwater resources. Bank infiltration on the floodplains of the Second Songhua River is ...
