BACKGROUND Persistent hyperparathyroidism (HPT) is frequently observed in kidney transplant recipients. Hypophosphataemia is a common biochemical consequence of HPT. Theoretically, oral phosphorus administration may induce negative effects on the control of HPT, though this point has never been demonstrated in kidney-transplant recipients. This study was(More)
In order to identify faster-growing non-woody species usable for biomass and paper production, four Leucaena species (L.diversifolia, L. colinsii, L. salvadorensis and three varieties of L. leucocephala) were tested. All the Leucaena species showed a good soil and climatic adaptation to Spain Southwest except for L. salvadorensis. Studied Leucaena species(More)
The pathogenesis of hypertension induced by recombinant human erythropoietin (rHuEPO) remains a subject of intense interest. The observation that patients treated with antiplatelet drugs never developed hypertension following rHuEPO therapy prompted us to study retrospectively the incidence and risk factors associated with the development of hypertension in(More)
This manuscript reports the usefulness of the determination of sulphathiazole (ST) using photochemically induced fluorescence (RTPF) and RTPF coupling with first derivative (D1-RTPF), and the determination of sulphanilamide (SAN) by meaning first derivative of the emission spectrum. By irradiating 5 min, with intense UV radiation, sulphathiazole, in(More)
The host-guest inclusion complexes of sulphamethoxazole (SMTX) and sulphaguanidine (SGN) with β-cyclodextrin, in aqueous solutions, have been investigated. A 1:1 stoichiometry of the complexes was established, the association constants were calculated by different methods, and the influence of several chemical variables on the complexation processes were(More)
In order to identify faster-growing non-woody species usable for biomass and paper production, four Tagasastes (Chamaecytisus proliferus) from different origins are tested. All the Tagasaste species (T. Huelva, T. Australia, T. New Zealand and T. La Palma island) show a good soil and climatic adaptation to Southwest Spain. The studied Tagasaste provenances(More)
We studied 28 patients with parathyroid hormone (PTH) concentrations >65 pg/ml immediately prior to kidney transplant and who had stable allograft function with serum creatinine <2 mg/dl. After 12-18 months of transplantation, biochemical parameters (including 25-hydroxy- and 1,25-dihydroxy-vitamin D3) were studied. Patients were divided into three groups(More)
Erythrocyte ferritin may be a better estimator of iron bioavailability than the conventional markers of iron stores (serum ferritin and transferrin saturation). To investigate the accuracy of these conventional markers in uremic patients compared with erythrocyte ferritin, we studied 29 chronic hemodialysis patients on erythropoietin (EPO) therapy, 18(More)
The increase in patients on dialysis awaiting transplantation has led to the use of grafts from suboptimal donors. The aim of this study was to analyze the function of suboptimal grafts. The secondary objectives were to study vascular and urological complications, as well as delayed renal function and acute rejection episodes. The study included 135(More)
A protective effect of obesity on the mortality of end-stage renal failure patients has been observed in several studies. Most of these studies have been based on prevalent dialysis population. The aim of the present study was to evaluate if obesity has beneficial effects on the survival of advanced chronic renal failure patients. The study group consisted(More)
