Venom complexity of Bothrops atrox (common lancehead) siblings

Variability in snake venoms is a well-studied phenomenon. However, sex-based variation of Bothrops atrox snake venom using siblings is poorly investigated. Bothrops atrox is responsible for the majority of snakebite accidents in the Brazilian Amazon region. Differences in the venom composition of Bothrop...

Venom peptides in association with standard drugs: a novel strategy for combating antibiotic resistance - an overview

Development of antibiotic resistance that leads to resurgence of bacterial infections poses a threat to disease-free existence for humankind and is a challenge for the welfare of the society at large. Despite research efforts directed towards treatment of pathogens, antibiotics within new improved classe...

Availability of biological cancer drugs under research: registration and price in Brazil, Colombia, and Mexico

Physis (Rio J.); 30 (4), 2020
Abstract This study seeks to understand biological cancer drug availability through registration and prices of the biological agents used for cancer therapy and authorized for sale in the last 5 years in Brazil, Colombia, and Mexico, comparing the data to those for the United States of America (USA) and ...

Role of crotoxin in coagulation: novel insights into anticoagulant mechanisms and impairment of inflammation-induced coagulation

Snake venom phospholipases A2 (svPLA2) are biologically active toxins, capable of triggering and modulating a wide range of biological functions. Among the svPLA2s, crotoxin (CTX) has been in the spotlight of bioprospecting research due to its role in modulating immune response and hemostasis. In the pre...

Effect of ethanol extracts of Antrodia cinnamomea on head and neck squamous cell carcinoma cell line

Braz. j. med. biol. res; 53 (6), 2020
Head and neck squamous cell carcinoma (HNSCC) is one of the most common malignant tumors. Ethanol extract of Antrodia cinnamomea (EEA) has been widely studied for its health benefits including anticancer effects. The purpose of this study was to assess the effects of EEA on HNSCC. Cell proliferation, tra...

Experimental evaluation of intra-abdominal adhesions comparing two different intraperitoneal meshes and the effect of a natural anti-inflammatory product on their formation

Acta cir. bras; 35 (12), 2020
Abstract Purpose: In laparoscopic incisional hernia repair, meshes with a tissue-separating barrier are positioned intraperitoneally. Despite this property, the close contact between mesh and viscera involves a risk of adhesion formation. Some natural products, such as red propolis (RP), could reduce th...

Exploring the shared genes of hypertension, diabetes and hyperlipidemia based on microarray

Given their relationship with metabolic syndrome and systematic inflammatory diseases, the pathogenesis of hypertension, hyperglycemia, and hyperlipidemia is closely related. To explore the common genes among these three conditions, spontaneous hypertensive rats (SHR), spontaneous diabetic Goto-Kakizaki ...

Incidence of tuberculosis infection in spondyloarthritis patients treated with biological and conventional disease-modifying anti-rheumatic drugs in an endemic area

Clin. biomed. res; 40 (1), 2020
Introduction: Registries of spondyloarthritis (SpA) patients’ follow-up provided evidence that tumor necrosis factor inhibitors (TNFi) increase the incidence of active tuberculosis infection (TB). However, most of these registries are from low burden TB areas. Few studies evaluated the safety of biolog...

Perillyl alcohol has antibacterial effects and reduces ROS production in macrophages

J. appl. oral sci; 28 (), 2020
Abstract Natural products have emerged as a rich source of bioactive compounds for adjunctive treatments of many infectious and inflammatory conditions, including periodontitis. Among the monoterpenes with significant biological properties, there is the perillyl alcohol (POH), which can be found in sever...
