How arsenic (As) is transported in phloem remains unknown. To help answer this question, we quantified the chemical species of As in phloem and xylem exudates of castor bean (Ricinus communis) exposed to arsenate [As(V)], arsenite [As(III)], monomethylarsonic acid [MMA(V)], or dimethylarsinic acid. In the As(V)- and As(III)-exposed plants, As(V) was the(More)
OBJECTIVE Several studies have suggested that non-diabetic renal disease (NDRD) was common among non-insulin dependent diabetes mellitus (NIDDM) patients with renal involvement. METHODS The prevalence of NDRD among Chinese NIDDM population in PUMC hospital center was retrospectively studied. Renal biopsy specimens were evaluated with light-,(More)
OBJECTIVE To evaluate the long-term effects of arteriovenous fistula (AVF) on heamodynamic changes and cardiac structure and function in non-diabetic hemodialysis patients. METHODS Data were collected from 50 non-diabetic hemodialysis patients (aged 18 to 60 years) who had used AVF as the vascular access. AVF flow (Qa), stoke volume (SV), cardiac output(More)
Data on PCP in patients with glomerular disease are rare. The aim of this study was to assess the predictors of PCP development, the risk factors for mortality and the incidence of acute kidney injury (AKI) when high-dose trimethoprim–sulphamethoxazole (TMP-SMX) was used in patients with non-transplant glomerular disease. Forty-seven patients with PCP, as(More)
OBJECTIVE To prospectively determinate the association of left ventricular systolic and diastolic function with intradialytic hypotension (IDH) in patients on maintenance hemodialysis. METHODS Totally 115 patients with sinus rhythm were included in this study and divided into IDH group (n=29) and control group (n=86). The cardiac function was assessed by(More)
OBJECTIVE To evaluate the clinical features, renal histopathology and therapeutic response to glucocorticoid and immunosuppressive agents in patients with glomerular disease associated with Takayasu arteritis (TA). METHODS Patients with TA and renal biopsy-confirmed glomerular disease were investigated retrospectively. None of them had renal artery(More)
Arsenic (As) accumulation in food crops such as rice is of major concern. To investigate whether phytoremediation can reduce As uptake by rice, the As hyperaccumulator Pteris vittata was grown in five contaminated paddy soils in a pot experiment. Over a 9-month period P. vittata removed 3.5-11.4% of the total soil As, and decreased phosphate-extractable As(More)
