Chagas' disease is accompanied by severe anemia and oxidative stress, which may contribute to mortality. In this study, we investigated the role of 5-lipoxygenase (5-LO) in the control of parasitism and anemia associated with oxidative damage of erythrocytes in experimental Trypanosoma cruzi infection. Wild-type C57BL/6, 129Sv mice treated or not with nordihydroguaiaretic acid (NDGA, 5-LO inhibitor), mice lacking the 5-LO enzyme gene (5-LO(-/-)) and inducible nitric oxide synthase gene (iNOS(-/-)) were ...

Prostaglandins are known to be produced by macrophages when challenged with Trypanosoma cruzi, the etiological agent of Chagas' disease. It is not known whether these lipid mediators play a role in oxidative stress in host defenses against this important protozoan parasite. In this study, we demonstrated that inducible cyclooxygenase-mediated prostaglandin production is a key chemical mediator in the control of parasite burden and erythrocyte oxidative stress during T. cruzi infection in C57BL/6 ...

Abstract Although anatomical variations in the arterial pattern of the hand have been the subject of many studies, information on the diameter of the superficial palmar arch contributing vessels and its branches are rarely found in the literature. The objective of the current study was to evaluate these arterial variations, with special attention to the diameter of the superficial palmar arch contributing vessels and its major branches. Forty‐six hands from male embalmed human cadavers were evaluated, ...

Background The estimated glomerular filtration rate is a rather important measurement for patients under intensive care, since they often receive several drugs, and impaired renal function may result in misleading dosing. The estimated glomerular filtration is derived from mathematical models using serum creatinine, a measurement that suffers interference of some drugs, such as metamizole. This study intended to evaluate the impact on patient stratification for dose adjustment of two antimicrobials ( ...

The fifth-generation of mobile network (5G) and beyond requires a radio access network (RAN) update in order to cope with the incoming increase of wireless data traffic and new applications. In this context, we propose an efficient optical-wireless architecture applied to the non-standalone (NSA) 5G new radio (NR) framework. Several distinct electrical- and optical-based fronthaul configurations combining free-space optical (FSO), wireless links, and radio over fiber (RoF) techniques were implemented ...

Abstract Objective The aim of this study was to investigate the protective effects of probiotics and fecal transplantation on inflammatory and oxidative parameters in the intestines of two rat models of sepsis. Methods Rats were treated with prebiotics, probiotics, or symbiotics and exposed to lipopolysaccharide (LPS) or zymosan after 15 d to induce endotoxemia. Oxidative damage and inflammation were analyzed, and histologic examination of the intestinal tissue was performed. Fecal microbiota transplantation ( ...

Abstract We aim to characterize the kinetics of early and late microglial phenotypes after systemic inflammation in an animal model of severe sepsis and the effects of minocycline on these phenotypes. Rats were subjected to CLP, and some animals were treated with minocycline (10 ug/kg) by i.c.v. administration. Animals were killed 24 hours, 5, 10 and 30 days after sepsis induction, and serum and hippocampus were collected for subsequent analyses. Real‐time PCR was performed for M1 and M2 markers. ...

We theoretically investigate the implementation of a quantum controlled-phase gate in a system constituted by a single atom inside an optical cavity, based on the electromagnetically induced transparency effect. First we show that a probe pulse can experience a $\ensuremath{\pi}$ phase shift due to the presence or absence of a classical control field. Considering the interplay of the cavity-EIT effect and the quantum memory process, we demonstrated a controlled-phase gate between two single photons. ...

The present research investigated the removal of zinc from BOF (basic oxygen furnace) sludges in an attempt to reuse the iron content of the sludge in the production of sinter. The study consisted of two main steps: (i) the characterization of fine and coarse fractions of BOF sludges and (ii) the hybrid treatment of sludge to selectively remove zinc from iron. The characterization study showed that the Fe/Zn ratio is 132.6 in the coarse fraction and 11.6 in the fine fraction; the amount of zinc proved ...
