Phosphorus loading and measurement is of concern on lands where biosolids have been applied. Traditional soil testing for plant-available P may be inadequate for the accurate assessment of P loadings in a regulatory environment as the reported levels may not correlate well with environmental risk. In order to accurately assess potential P runoff and leaching, as well as plant uptake, we must be able to measure organic P mineralized by the biotic community in the soil. Soils with varying rates of biosolid application were evaluated for mineralized organic P during a 112-day incubation using the difference between P measured using a rapid-flow analyzer (RFA) and an axial flow varian ICP-OES. An increase in the P mineralized from the treated soils was observed from analysis with the varian ICP-OES, but not with the RFA. These results confirm that even though organic P concentrations have increased due to increasing biosolid application, traditional soil testing using an RFA for detection, would not accurately portray P concentration and potential P loading from treated soils.

Aim: To evaluate left ventricular (Lv) diastolic function in children with end-stage renal disease (ESRD) using conventional pulsed-Doppler echocardiography and Doppler tissue imaging (DTI), and to compare the findings with these two modalities. Methods: Twenty-four children with ESRD and 22 healthy age-and sex-matched control subjects were assessed with conventional Doppler echocardiography and DTI. The scans of the renal disease patients were done after a dialysis session. Parameters related to Lv systolic and diastolic function were compared in the ESRDand control groups. Results: The ESRD patients had lower mean mitral E/A ratio both according to conventional Doppler echocardiography and TDI than the control subjects. The ESRD group also had significantly longer isovolumetric relaxation time (116 ±31 ms vs 97 ±3.1 ms, respectively; p nd significantly longer deceleration time (235 ±44 ms vs 202 ±35 ms, respectively; p n the control group. Conclusion: DTI findings correlate well with conventional Doppler echocardiography findings. Children with ESRD show, after dialysis, echocardiographic signs of Lv diastolic dysfunction.

Fusarium solani is a necrotrophic parasitic fungus that causes wilt in some plants, causing severe economic losses in some areas of the country. The objective of this work was to analyze the induction of extracellular lytic enzymes produced by a strain of F. solani, isolated from a culture of tomato, in villa de Arista, S.L.P. México. Polygalacturonase activity has a greater induction time at 10 days, and the xylanase has two times higher activity at 8 and 13 days of incubation at 28?C. Also, the xylanase activities A and B were very stable at 4?C. After 7 days of incubation, it has an activity of 100% and 96%, respectively, while polygalacturonase retains 61% of its initial activity. Both activities are better induced with glutamate and urea as nitrogen sources respectively, and both exhibit an initial pH optimum of 5.5. Finally, we didn’t find cellulase activity in the analyzing conditions.

Five wild plant species belonging to different families (Chenopodium album, Plantago major, Elytrigia elongata, Filipendula ulmaria and nigella sativa) widely spread in Russian Federation and the former USSR were evaluated for their ability to inhibit growth of two important human food-borne pathogens (Escherichia coli O157:H7 and Listeria monocytogenes strain EGD-e) and eight plant pathogens (Alternaria alternata, Alternaria tenuissima, Bipolaris sorokiniana, Stagonospora nodorum, Fusarium solani, Fusarium oxysporum, Fusarium culmorum and Phytophtora infestans). To isolate biologically active compounds from seeds, a step-wise procedure including extraction with hexane, ethyl acetate, ethanol, and 10% acetic acid followed by reversed-phase HPLC was developed. Using disc-diffusion assay, the highest activity against E. coli O157:H7 was observed with extracts from F. ulmaria (hexane and ethyl acetate extracts and the unbound RP-HPLC fraction) and P. major (ethyl acetate extract and the unbound RP-HPLC fraction);E. elongate (the unbound RP-HPLC fraction) was less active. The extracts from P. major and E. elongate (the unbound RP-HPLC fractions) were equally highly active against L. monocytogenes, while those of F. ulmaria (the unbound RP-HPLC fraction) and n. sativa (hexane and ethyl acetate extracts) were less active against this pathogen. The dynamics of L. monocytogenes EGD-е and E. coli O157:H7 growth in the presence of two most potent extracts (RP-HPLC-unbound fractions of P. major and E. elongate and the hexane extract of F. ulmaria) was studied.
