The SARS-CoV-2 virus, responsible for COVID-19, spread rapidly worldwide and became a pandemic in 2020. In some patients, the virus remains in the respiratory tract, causing pneumonia, respiratory failure, acute respiratory distress syndrome (ARDS), and sepsis, leading to death. Natural flavonoids (aglycone and glycosides) possess broad biological activities encompassing antiinflammatory, antiviral, antitumoral, antiallergic, antiplatelet, and antioxidant effects.

There is a strong correlation between obesity and cancer. Here, we investigated the influence of IL-6 and gut microbiota of obese mice in melanoma development. We first evaluated B16F10 melanoma growth in preclinical models for obesity: mice deficient for leptin ) or adiponectin (AdpKO) and in wild-type mice (WT, C57BL/6J) fed a high-fat diet (HFD; 60% kcal from fat) for 12 weeks.

The antitumor effect of metformin has been demonstrated in several types of cancer; however, the mechanisms involved are incompletely understood. In this study, we showed that metformin acts directly on melanoma cells as well as on the tumor microenvironment, particularly in the context of the immune response. , metformin induces a complex interplay between apoptosis and autophagy in melanoma cells.

The role of plasma glutamine concentration and glutamine supplementation on immunosuppression was investigated in combat athletes. Twenty-three male athletes were randomly assigned to receive glutamine (21 g/day, n=12) or placebo (ovalbumin, n=11) for 10 days. Six athletes who did not lose weight served as controls.

Acute renal failure (ARF) is a common renal disease that can lead to high mortality. Recovery from ARF occurs with the replacement of necrotic tubular cells by functional tubular epithelial cells and the normalization of microvascular endothelial cell function in the peritubular capillaries. Conventional therapeutic techniques are often ineffective against ARF.

Introduction: Adipose tissue is responsible for triggering chronic systemic inflammatory response and these changes may be involved in the pathophysiology of preeclampsia.

Objective: To characterize the lipid profile in the placenta and plasma of patients with preeclampsia.

Methodology: Samples were collected from placenta and plasma of 10 pregnant women with preeclampsia and 10 controls.

Objectives: The aim of this preliminary study was to characterize the plasma lipid profiling of women with preeclampsia.

Design And Methods: Plasma samples of 8 pregnant women with early-onset preeclampsia and 8 normal pregnant women were evaluated. Lipids were extracted from plasma using the Bligh-Dyer protocol.

Intense inflammatory response and an anti-angiogenic state have been implicated in the pathogenesis of preeclampsia. Here, we investigated this hypothesis evaluating the serum concentrations of CXCL10/IP-10, sFlt-1, and PlGF in women with early-onset preeclampsia. CXCL10/IP-10 was measured by Cytometric Bead Array.

Background: Acute rejection is the most important risk factor for graft survival. Although many centers start immunosuppressive therapy days before the surgery in living donors, there is no systematic study concerning the possible advantages of this procedure. In this open randomized study, we compared the efficacy and safety of administration of cyclosporine (CSA; Neoral) and azathioprine before renal transplantation with the administration of the same schema after transplantation, in HLA haploidentical grafts.
