Analysis of Complement Factor H gene polymorphisms and their association with clinical manifestations ofleptospirosis.

Leptospirosis is caused by pathogenic leptospires, posing a significant public health problem. Host susceptibility to Leptospira infection is a multifactorial trait, and the host's genetic background can influence both the establishment of infection and the severity of the disease. Complement Factor H (FH) plays a crucial role in the interaction between pathogenic bacteria and the host.

Syndecan-1 predicts hemodynamic instability in critically ill patients under intermittent hemodialysis.

Introduction: Up to 70% of intermittent hemodialysis (IHD) sessions in critically ill patients are complicated by hemodynamic instability. Although several clinical characteristics have been associated with hemodynamic instability during IHD, the discriminatory capacity of predicting such events during IHD sessions is less defined. In the present study, we aimed to analyse endothelium-related biomarkers collected before IHD sessions and their capacity to predict hemodynamic instability related to IHD in critically ill patients.

Methods: 10 young male futsal players (16.9 ± 0.

Association between angiopoietin-2 and functional cardiac remodeling in hemodialysis patients with normal left ventricular ejection.

Cardiac remodeling is the initial process in heart failure development. The aim of this study is to evaluate the association between endothelium-related biomarkers and cardiac remodeling in hemodialysis (HD) patients and how the presence of high blood pressure and diabetes mellitus modulates these associations. This was a cross-sectional study with adult HD and normal left ventricular (LV) ejection fraction-LVEF-patients.

Preliminary Study for New Markers of Early Tubuloglomerular Injury and Renal Inflammation in Patients with Visceral Leishmaniasis Receiving Liposomal Amphotericin B Treatment.

Visceral leishmaniasis is treated with liposomal amphotericin B (L-AMB), which is associated with nephrotoxicity. Thus, we aimed to investigate nephrotoxicity through novel renal biomarkers in patients with visceral leishmaniasis during L-AMB use. Ours was a prospective study with 17 patients with visceral leishmaniasis treated with L-AMB during their hospital stay.

The Effects of Successive Soccer Matches on the Internal Match Load, Stress Tolerance, Salivary Cortisol and Jumping Performance in Youth Soccer Players.

The study aim was to analyze the effects of successive matches on the internal match load, stress tolerance, salivary cortisol concentration and countermovement vertical jump height in twelve youth soccer players (16.6 ± 0.5 yr; 175 ± 8 cm; 65 ± 8 kg) who performed four official matches within a four day-period with a 24-h recovery interval between the matches.

Intraoperative systemic biomarkers predict post-liver transplantation acute kidney injury.

Objective: Liver transplant (LT) is a definitive therapeutic option for patients with chronic liver disease. However, acute kidney injury after LT (post-LT AKI) is a frequent complication that may lead to graft dysfunction and decrease life expectancy. Delay in AKI detection by traditional biomarkers boosted research with new biomarkers for post-LT AKI as neutrophil gelatinase-associated lipocalin (NGAL) and syndecan-1.

The Effects of the Alkaloid Tambjamine J on Mice Implanted with Sarcoma 180 Tumor Cells.

The tambjamines are a small group of bipyrrolic alkaloids that, collectively, display a significant range of biological activities including antitumor, antimicrobial and immunosuppressive properties. The key objective of the present study was to undertake preclinical assessments of tambjamine J (T-J) so as to determine its in vivo antitumor effects. To that end, sarcoma 180 cells were transplanted in mice and the impacts of the title compound then evaluated using a range of protocols including hematological, biochemical, histopathological, genotoxic and clastogenic assays.

Infection by Schistosoma mansoni during pregnancy: Effects on offspring immunity.

About 25 million Brazilians live in areas at risk of contracting the disease caused by the trematoda Schistosoma mansoni, the schistosomiasis mansoni. Although the adult parasites inhabit the blood vessels, probably the main element responsible for the pathology of the disease are the eggs, whose deposition in the liver results in formation of granulomas and hypersensitivity mediated by CD4 T cells. In the course of infection, the profile of T helper 1 (Th1) and Th2 cytokines released by immune cells is correlated with the extent of inflammation in the granuloma and with the disease severity.
