This is the fourteenth edition of this database of evidence on potential therapeutic options for COVID-19, in which 68 therapeutic options are examined. This information will help investigators, policy makers, and prescribers navigate the flood of relevant data to ensure that management of COVID-19, at b...

Enhancement of cellular activity in hyperglycemic mice dermal wounds dressed with chitosan-alginate membranes

Braz. j. med. biol. res; 53 (1), 2020
The use of specially designed wound dressings could be an important alternative to facilitate the healing process of wounds in the hyperglycemic state. Biocompatible dressings combining chitosan and alginate can speed up wound healing by modulating the inflammatory phase, stimulating fibroblast prolifera...

Total Panax notoginseng saponin inhibits balloon injury-induced neointimal hyperplasia in rat carotid artery models by suppressing pERK/p38 MAPK pathways

Braz. j. med. biol. res; 53 (1), 2020
Total Panax notoginseng saponin (TPNS) is the main bioactivity compound derived from the roots and rhizomes of Panax notoginseng (Burk.) F.H. Chen. The aim of this study was to investigate the effectiveness of TPNS in treating vascular neointimal hyperplasia in rats and its mechanisms. Male Sprague-Dawle...

CCR3 antagonist impairs estradiol-induced eosinophil migration to the uterus in ovariectomized mice

Braz. j. med. biol. res; 53 (1), 2020
Eosinophils are abundant in the reproductive tract, contributing to the remodeling and successful implantation of the embryo. However, the mechanisms by which eosinophils migrate into the uterus and their relationship to edema are still not entirely clear, since there are a variety of chemotactic factors...

Feasibility of non-intubated anesthesia and regional block for thoracoscopic surgery under spontaneous respiration: a prospective cohort study

Braz. j. med. biol. res; 53 (1), 2020
Data about the feasibility and safety of thoracoscopic surgery under non-intubated anesthesia and regional block are limited. In this prospective study, 57 consecutive patients scheduled for thoracoscopic surgery were enrolled. Patients were sedated with dexmedetomidine and anesthetized with propofol and...

Chlorophyll treatment combined with photostimulation increases glycolysis and decreases oxidative stress in the liver of type 1 diabetic rats

Braz. j. med. biol. res; 53 (1), 2020
Photodynamic therapy (PDT) promotes cell death, and it has been successfully employed as a treatment resource for neuropathic complications of diabetes mellitus (T1DM) and hepatocellular carcinoma. The liver is the major organ involved in the regulation of energy homeostasis, and in pathological conditio...

Effect of fasudil on experimental autoimmune neuritis and its mechanisms of action

Braz. j. med. biol. res; 53 (1), 2020
This study aimed to investigate the therapeutic effect of fasudil on treating experimental autoimmune neuritis (EAN). Twenty-four EAN mice were randomly assigned to fasudil treatment (Fasudil group) or saline treatment (EAN model group) for 28 days. Clinical symptom score was evaluated every other day; i...

Euterpe Oleracea Mart. (Açaí) Reduces Oxidative Stress and Improves Energetic Metabolism in Myocardial Ischemia-Reperfusion Injury in Rats

Arq. bras. cardiol; 114 (1), 2020
Abstract Background: Euterpe oleracea Mart. (açaí) is a fruit with high antioxidant capacity and could be an adjuvant strategy to attenuate ischemia-reperfusion injury. Objective: To evaluate the influence of açaí in global ischemia-reperfusion model in rats. Methods: Wistar rats were assigned to ...

Spinal protein kinase A and phosphorylated extracellular signal-regulated kinase signaling are involved in the antinociceptive effect of phytohormone abscisic acid in rats

Arq. neuropsiquiatr; 78 (1), 2020
Abstract Objective: The phytohormone abscisic acid (ABA) as a signaling molecule exists in various types of organisms from early multicellular to animal cells and tissues. It has been demonstrated that ABA has an antinociceptive effect in rodents. The present study was designed to assess the possible r...
