Interaction of lipophorin with Rhodnius prolixus oocytes: biochemical properties and the importance of blood feeding

Lipophorin (Lp) is the main haemolymphatic lipoprotein in insects and transports lipids between different organs. In adult females, lipophorin delivers lipids to growing oocytes. In this study, the interaction of this lipoprotein with the ovaries of Rhodnius prolixus was characterised using an oocyte membrane preparation and purified radiolabelled Lp (125I-Lp). Lp-specific binding to the oocyte membrane reached equilibrium after 40-60 min and when 125I-Lp was incubated with increasing amounts of membrane protein, corresponding increases in Lp binding were observed. The specific binding of Lp to the membrane preparation was a saturable process, with a Kdof 7.1 ± 0.9 x 10-8M and a maximal binding capacity of 430 ± 40 ng 125I-Lp/µg of membrane protein. The binding was calcium independent and pH sensitive, reaching its maximum at pH 5.2-5.7. Suramin inhibited the binding interaction between Lp and the oocyte membranes, which was completely abolished at 0.5 mM suramin. The oocyte membrane preparation from R. prolixus also showed binding to Lp from Manduca sexta. When Lp was fluorescently labelled and injected into vitellogenic females, the level of Lp-oocyte binding was much higher in females that were fed whole blood than in those fed blood plasma.

Diabetic nephropathy: changes after diabetes surgery?

Introduction: Obesity, as a central piece inside metabolic syndrome, is associated with early chronic kidney disease (CKD). In addition, several observational, cross sectional, and longitudinal studies have demonstrated that obesity is as an independent risk factor for the onset, aggravated course, and poor outcomes of CKD including diabetic nephropathy. This implies that when obesity is reversed, many CKD risk factors and CKD itself could be favorably influenced. So all measures aimed at weight loss are recommended to minimize risks from obesityrelated conditions and generate improvements in the metabolic profile. Recent evidence shows that bariatric surgery (BS) can revert or improve proteinuria and CKD in morbidly obese patients. Objectives and methods: The present review is aimed to provide the evidence regarding the beneficial effects of weight loss after BS in different stages of CKD including kidney transplant recipients, with an special focus on the beneficial effect in reducing or improving proteinuria and renal failure. Furthermore, this updated systematic review of the literature analyzes potential adverse effects that BS could induce not only on renal function but also on morbidity and mortality risk in perioperative and postoperative period. Conclusions: Results from the different case reports, meta analysis as well as systematic review of clinical trials show that obesity treatment by way of lifestyle changes, pharmacotherapies and BS can reduce proteinuria and help to prevent loss of renal function. Also BS may reduce complications, and allow obese patients with end-stage renal disease to undergo kidney transplantation with good results.

Una visión global y actual de los edulcorantes. Aspectos de regulación.

In this chapter we review the role and potential benefits of non-caloric sweeteners, as part of the diet. After appearing and interest in the beneficial effects attributed to them, face different situations and conditions (obesity, diabetes...), more and more numerous studies, show their ineffective use. In conclusion, further research and results are needed to provide convincing evidence of their long-term effectiveness and the absence of negative effects from their use. The interest of the chapter lies in examining the distinctive aspects of sweeteners compared with sugar, measured as the standard of comparison. We will focus then on the other substances that are commonly used to sweeten foods instead of sugar.

Productive HIV-1 infection of primary CD4+ T cells induces mitochondrial membrane permeabilization leading to a caspase-independent cell death.

We have explored in vitro the mechanism by which human immunodeficiency virus, type 1 (HIV-1) induces cell death of primary CD4+ T cells in conditions of productive infection. Although HIV-1 infection primed phytohemagglutinin-activated CD4+ T cells for death induced by anti-CD95 antibody, T cell death was not prevented by a CD95-Fc decoy receptor, nor by decoy receptors of other members of the TNFR family (TNFR1/R2, TRAILR1/R2/OPG, TRAMP) or by various blocking antibodies, suggesting that triggering of death receptors by their cognate ligands is not involved in HIV-induced CD4 T cell death. HIV-1 induced CD4 T cell shrinkage, cell surface exposure of phosphatidylserine, loss of mitochondrial membrane potential (Deltapsim), and mitochondrial release of cytochrome c and apoptosis-inducing factor. A typical apoptotic phenotype (nuclear chromatin condensation and fragmentation) only occurred in around half of the dying cells. Treatment with benzyloxycarbonyl-Val-Ala-Asp-fluoromethylketone, a broad spectrum caspase inhibitor, prevented nuclear chromatin condensation and fragmentation in HIV-infected CD4+ T cells and in a cell-free system (in which nuclei were incubated with cytoplasmic extracts from the HIV-infected CD4+ T cells). Nevertheless, benzyloxycarbonyl-Val-Ala-Asp-fluoromethylketone did not prevent mitochondrial membrane potential loss and cell death, suggesting that caspases are dispensable for HIV-mediated cell death. Our findings suggest a major role of the mitochondria in the process of CD4 T cell death induced by HIV, in which targeting of Bax to the mitochondria may be involved.
