Microscopic evidence confirms that L. cruciata hosting G. proliferum shows major anatomical traits (arbuscules, coils, arbusculate coils and vesicles) generally associated arbuscular mycorrhizal roots and the anatomical morphology of intra-thalli mycelium is predominantly of the Paris-type. Colonised L. cruciata showed a reduction of biomass when compared with axenic plants suggesting a drain o...
The nucleic acids fall into two broad categories. The desoxypentose nucleic acids (DNA), in mammalian tissues, are found only in cell nuclei associated with the chromosomes (1,2). The pentose nucleic acids (PNA) are chiefly cytoplasmic (3), but are also found in smaller amounts in the nucleolus (4) and in the residual chromosomes (5, 1). Various studies have shown that the phosphorus of the des...
1. Chinese end-stage renal disease patients on continuous ambulatory peritoneal dialysis (CAPD) show a high prevalence of cardiovascular diseases (CVD) including: left ventricular hypertrophy (95%) and dilatation (92%), left ventricular systolic (35%) and diastolic dysfunction (79%), congestive heart failure (39%), coronary artery disease (23.5%), and cardiac valve calcifications (24%). 2. Apar...
The over-application of phosphorus, as manure by animal feeding operations, is a threat to surface water quality. Concentration of animal feeding operations and over application of manures to cropland has lead to a build-up of phosphorus on many farms (Greaves et al., 1999). Relative to crop needs, manure slurries contain higher levels of phosphorus than nitrogen. When manure is applied to meet...
The pathogenesis and management of chronic kidney disease-mineral bone disorders (CKD-MBD) has experienced major changes, but the control of serum phosphorus at all stages of CKD still seems to be a key factor to improve clinical outcomes. High serum phosphorus is the most important uremia-related, non-traditional risk factor associated with vascular calcification in CKD patients and in the gen...
We applied the SPARROW model to estimate phosphorus transport from catchments to stream reaches and subsequent delivery to major receiving water bodies in the Southeastern United States (U.S.). We show that six source variables and five land-to-water transport variables are significant (p<0.05) in explaining 67% of the variability in long-term log-transformed mean annual phosphorus yields. Thre...
The aim of this study was evaluation of stability of immobilized phospholipase A2 (PLA2) for soybean oil degumming. Also, the effect of reaction time on residual phosphorus levels was investigated according to the optimum pH and temperature. The free PLA2 and three immobilized PLA2 demonstrated significant differences in optimum operation conditions. pH, temperature and reaction time increased ...
With the goal of facilitating the development of surface micromachined polysilicon MEMS with postprocessed on-chip circuitry, we have evaluated the impact of a 1200 C 16-h anneal upon chemical-vapor-deposited (CVD) polysilicon under a variety of processing conditions. The results show that undoped polysilicon has a final stress of +10–20 MPa even when the films are vastly different as deposited...
The effect of successive applications of urban compost (up te 150 and 400 t ha-1 during eight years) en the status ef phosphorus in a calcareous soíl (20%) was testad in a greenhouse experimento An 6-15-15 complex fertiliser was also applied for comparison. Five years of ryegrass and three of horticultural plants (tomate and eggplant) were successively cropped during the experimento Increases o...
