A total of 901 EV proteins were identified, 328 of which were commonly found in the three types of EVs. selleck compound GO analysis revealed that these proteins were mainly involved in binding (44%) and catalytic activity (44%). Three types of EVs were different in biomarkers (Enolase and 14-3-3) and in reactivity with anti-echinococcosis positive serum. Moreover, 110K EVs were more easily internalized by hepatic cells than 10K EVs as well as 2K EVs (p less then 0.0001). These results reveal the physical and biological discrepancy among 2K, 10K and 110K EVs, suggesting a distinct role in host-parasite interactions.Cutaneous Leishmaniasis (CL) is a vector-borne disease caused by Leishmania species and transmitted by infected female sand flies. CL is widely distributed in Brazil, but knowledge about vectors and transmission cycles could be complex according to localities. The sand fly fauna in Rondônia State is extensive, diverse, and largely unexplored. Although the state records a mean of 1,000 CL cases per year, the vectors of CL are unknown. The aim of this study was to assess phlebotomine sand fly fauna composition using diversity indexes (Shannon [H'] and Simpson [1/D]) and to detect the prevalence of Leishmania infection to verify potential vectors in three ecotopes (i) forest fragment (FF), (ii) forest edge (FE), and (iii) peridomicile (PE). Captures were performed in four rural districts in the municipality of Porto Velho. A total of 7,026 specimens were captured comprising 72 species, and individuals classified in subgenus level. Overall, the most abundant species were Lutzomyia davisi (n 1,105), Lutzomyia melloi (n 760), Lutzomyia auraensis (n 738) and Lutzomyia antunesi (n 479). Fauna was most diverse in the FF ecotope (H' = 20.2, 1/D = 11.2), followed by the FE (H' = 18.0, 1/D = 10.1) and PE (H' = 16.6, 1/D = 10.1) ecotopes. Leishmania DNA was detected in 24 of 232 pools. In every ecotope, Leishmania naiffi DNA was identified in the following sand fly species Lu. antunesi, Lu. davisi, Lu. hirsuta hirsuta, Lu. shawi, Lu. sordellii and Lu. (Trichophoromyia) spp. This observation may indicate that a Le. naiffi transmission focus is present in the study localities. In addition, Leishmania lainsoni was detected in Lutzomyia (Trichophoromyia) spp. Our findings show that sand fly fauna in the study localities is diverse, that Leishmania parasites are circulating in all three ecotopes, and that some sand fly species may be implicated in the transmission of Leishmania to humans in localities evaluated.The placenta is a highly metabolically active organ fulfilling the bioenergetic and biosynthetic needs to support its own rapid growth and that of the fetus. Placental metabolic dysfunction is a common occurrence in preeclampsia although its causal relationship to the pathophysiology is unclear. At the outset, this may simply be seen as an "engine out of fuel." However, placental metabolism plays a vital role beyond energy production and is linked to physiological and developmental processes. In this review, we discuss the metabolic basis for placental dysfunction and propose that the alterations in energy metabolism may explain many of the placental phenotypes of preeclampsia such as reduced placental and fetal growth, redox imbalance, oxidative stress, altered epigenetic and gene expression profiles, and the functional consequences of these aberrations. We propose that placental metabolic reprogramming reflects the dynamic physiological state allowing the tissue to adapt to developmental changes and respond to preeclampsia stress, whereas the inability to reprogram placental metabolism may result in severe preeclampsia phenotypes. Finally, we discuss common tested and novel therapeutic strategies for treating placental dysfunction in preeclampsia and their impact on placental energy metabolism as possible explanations into their potential benefits or harm. We describe contraception and dual method use among women with HIV initiating antiretroviral therapy (ART) in a U.S. clinical trial and examine associated factors. We analyzed data from ART-naïve women aged 45 years and under initiating one of 3 regimens as part of A5257 (May 2009-June 2011) which required that women at risk for pregnancy use contraception. We classified self-reported methods as more effective (Tier 1 [intrauterine device, hysterectomy, permanent contraception] and Tier 2 [hormonal rings, patches, injections, pills]) versus less effective (Tier 3 [condoms alone] and Tier 4 [withdrawal, none]). We used logistic regression models to assess associations with use of (a) more effective, and (b) dual methods (condoms with a more effective method). Of 285 women, majority were Black (59%), had annual income <$20,000 (54%), and had government insurance (68%). The most common contraceptive methods reported at baseline were permanent contraception (37%), male condoms alone (31%), and injectableervices, including in the context of clinical trials. Abortion is often characterized as an inherently difficult decision, despite research demonstrating high decision certainty among abortion patients. Minimal research has examined decision certainty among people planning to continue a pregnancy. We examined whether women seeking abortion experience lower decision certainty than those planning to continue pregnancies and whether certainty differs by pregnancy intendedness. We administered the decisional conflict scale (DCS) to pregnant women (n=149) at 8 U.S. primary and reproductive health clinics. Using Poisson regression models adjusted for sociodemographic and pregnancy characteristics, we evaluated differences in DCS scores (<25/100 vs ≥25/100) by pregnancy decision and whether pregnancy intention modified the effect of pregnancy decision on certainty. Over one-half (58%) of respondents planned to have an abortion, 32% to continue the pregnancy, and 10% were unsure. DCS scores were low overall (median 9.4/100; IQR 1.6, 25.0), indicative of high cence of some uncertainty among respondents continuing pregnancies suggests voluntary options counseling may be useful for some patients in prenatal care settings.Similar levels of uncertainty among individuals who decided to have an abortion versus continue a pregnancy challenge the narrative that abortion is a particularly difficult medical and personal decision. The prevalence of some uncertainty among respondents continuing pregnancies suggests voluntary options counseling may be useful for some patients in prenatal care settings.
