Background:Hemodialysis(HD) per se is a risk factor for *** the growing body of evidence on blood-flow restriction(BFR) exercise in HD patients,identification of possible risk factors related to the prothrombotic agent D-dimer is required for the safety and feasibility of this training *** aim of the present study was to identify risk factors associated with higher D-dimer levels and to determine the acute effect of resistance exercise(RE) with BFR on this ***:Two hundred and six HD patients volunteered for this study(all with a glomerular filtration rate of ded concentric and eccentric lifting phases(each lasting 2 s) and were supervised by a strength and conditioning ***:Several variables were associated with elevated levels of D-dimer,including higher blood glucose,citrate use,recent cardiovascular events,recent intercurrents,higher inflammatory status,catheter as vascular access,older patients(>70 years old),and HD ***,RE+BFR significantly increases D-dimer after 4 *** with borderline baseline D-dimer levels(400-490 ng/mL) displayed increased risk of elevating D-dimer over the normal range(≥500 ng/mL).Conclusion:These results identified factors associated with a heightened prothrombotic state and may assist in the screening process for HD patients who wish to undergo RE+BFR.D-dimer and/or other fibrinolysis factors should be assessed at baseline and throughout the protocol as a precautionary measure to maximize safety during RE+BFR.

Effluent of a Polyculture System(Tilapias and Shrimps):Assessment by Mass Balance of Nitrogen and Phosphorus

From the estimation of the mass balance model, which can also be classified as “black box” model, it is possible to infer the impact of management on the system considered. This study aimed to evaluate water pollution generated by wastewater from a polyculture system of tilapia and shrimp and discuss the management employee and their relation to the quality of the effluent released. It used a pond measuring 1500 m2, average depth 1.6 meters, where 12 cages of 1 m3 populated with tilapia juveniles were installed 33 days after the shrimps’ population. The tilapia juveniles were distributed in densities from 200 to 400 fish per cubic meter, reaching the density of 2.4 fish per square meter within the total pond area. Shrimp post-larvae were released outside the cages within the pond area in a density of 3.3 organisms per square meter. Total density considering fish and shrimps was of 5.7 organisms per square meter in the pond area. Water samples were taken weekly in affluent and effluent of the pond (January-August/2009). The mass balance model was calculated from the difference between the estimated load for the output and input of the pond. The average flow rate was 4.46 L/s. The average loads nitrogen was 0.072 Kg/day (affluent) and 0.179 Kg/day (effluent) and phosphorus 0.0136 Kg/day (affluent) and 0.031 Kg/day (effluent). The mass balance resulted in mean values of 0.11 ± 0.06 Kg/day for total nitrogen and 0.017 ± 0.010 Kg/day for total phosphorus indicating that the system exported nutrients. The use of Best Management Practices (BMP) likes better feed and water management as a way to minimize nutrient export.

A WW Domain-Containing Protein Forms Immune Nuclear Bodies against Begomoviruses

The bipartite begomoviruses (Geminiviridae family), which are DNA viruses that replicate in the nucleus of infected cells, encode the nuclear shuttle protein (NSP) to facilitate the translocation of viral DNA from the nucleus to the cytoplasm via nuclear pores. This intracellular trafficking of NSP-DNA complexes is accessorized by the NSP-interacting guanosine triphosphatase (NIG) at the cytosolic side. Here, we report the nuclear redistribution of NIG by AtWWPI, a WW domain-containing protein that forms immune nuclear bodies (NBs) against begomoviruses. We demonstrated that AtWWPI relocates NIG from the cytoplasm to the nucleus where it is confined to AtWWP1-NBs, suggesting that the NIG-AtWWP1 interaction may interfere with the NIG pro-viral function associated with its cytosolic localization. Consistent with this assumpti on joss AtWWPI functi on cuased plants more susceptible to begomovirus infection, whereas overexpression of AWWP1 enhaneed plant resistance to begomovirus. Furthermore, we found that a mutant versi on of AtWWPI defective for NB formatio n was noIonger capable of interacti ng with and relocating NIG to the nucleus and lost its immune function against begomovirus. The antiviral function of AtWWP1-NBs, however, could be antagonized by viral infection that induced either the disruption or a decrease in the number of AtWWP1-NBs. Collectively, these results led us to propose that AtWWPI organizes nuclear structures into nuclear foci, which provide intrinsic immunity against begomovirus infection.
