Sulfamethoxazole (SMX) is a broad-range bacteriostatic antibiotic widely used in animal and fish farming also employed human medicine. These antibiotics can ultimately end up the aquatic ecosystem affect non-target organisms such as fish. To discern effect of SMX on developing zebrafish embryos larvae, we investigated broad range sub-lethal toxicity endpoints. Higher concentrations affected survivability, caused hatch delay, induced malformations including edema yolk sac, pericardial...
Acetylcarvacrol is a semi-synthetic product derived from carvacrol and has known activity against ticks. In vertebrates, the thyroid been used as bioindicator in toxicity studies due to its sensitivity external factors. Thus, objective of this study was evaluate toxic effects acetylcarvacrol Wistar rats subjected repeated dose dermal oral tests by means histopathological analysis thyroid. For each test, were divided into 4 groups containing 5 animals. topical treatment applied trichotomized...
The species Uncaria tomentosa and guianensis are medicinal plants rich in bioactive compounds with anti-inflammatory properties. objectives of this study were to evaluate the potential these herbal medicines modulating phospholipases A2 proteases (involved hemostasis inflammation), using Bothrops moojeni venom as a model. To achieve this, plant extracts characterized for their phenolic composition by chromatography, action was evaluated through plate inhibition assays. phospholipase activity...
In recent years, studies on the potential use of essential oils (EOs) as pesticides have enormously increased owing to their remarkable biological activities and health benefits. However, given scant knowledge mode(s) action behind insecticidal activity individual oils, well mixtures, much more work has yet be undertaken. Furthermore, variable complex mixtures suggest that are likely due several mechanisms acting different physiological processes. Here, we firstly assessed toxicity Illicium...
Abstract Background The regular intake of fiber generates numerous health benefits. However, the efficacy depends on duration consumption and ingested dose. Studies investigating optimal dose are interest to enable inclusion in routine treatment diabetic patients. Objective We aimed evaluate effects different doses β-glucan (BG—isolated from Saccharomyces cerevisiae ), comparison n-3 supplement, inflammatory metabolic parameters Wistar rats induced diabetes by streptozotocin. Methods Forty...
Toxicity mechanisms of per- and polyfluoroalkyl substances (PFAS), a chemical class present in diverse ecosystems, are not well characterized aquatic species. Perfluorooctanesulfonamide (PFOSA, C8H2F17NO2S) is common precursor perfluorooctane sulfonic acid (PFOS), long-chain PFAS. Here, we assessed sub-lethal endpoints related to development, oxidative stress, locomotor activity, gene expression zebrafish embryos larvae following continuous exposure PFOSA beginning at 6 hours post...
The present work aims to investigate the impact of different drying processes on baru almonds. It was found that (65°C and 105°C for 30 min) did not change physicochemical, mineral quality composition almonds (except moisture acidity indexes decreased increased, respectively, use temperature min). All treatments are sources protein, fiber, lipids, boron, copper, manganese, iron, sulfur, calcium magnesium. below maximum limits established by inspection bodies presence peroxides, indicating...
An over-active renin-angiotensin system (RAS) is characterized by elevated angiotensin II (Ang II). While Ang can promote metabolic and mitochondrial dysfunction in tissues, little known about its role the gastrointestinal (GI). Here, we treated rat primary colonic epithelial cells to (1-5000 nM) better define GI. We hypothesized that would negatively affect bioenergetics as these organelles express receptors. increased cellular ATP production but reduced membrane potential (MMP) of...
The acaricidal and enzymatic inhibition potentials of extracts from lower quality green (GC) roasted (RC) coffee beans were analyzed. Coffee obtained using the solid-liquid reflux technique, in a 1:5 ratio. characterized by HPLC compounds identified comparison with retention times standards used. Acaricidal activity was assessed Adult Immersion Test (AIT) acetylcholinesterase determined monitoring formation 5-thio-2-nitrobenzoate. For every 100 g plant material, yields equal to 3.44% 13.34%...
Abstract Snake toxins, such as phospholipases A 2 and proteases, are used research tools to evaluate biological activities understand physiopathological processes of natural compounds better. In the present study, phenolic catechin epicatechin were incubated with snake venoms their inhibition against different substrates. Catechin exerted inhibitions between 20% 95% on activity in venom Bothrops alternatus . hemolytic activity, 25% all proportions evaluated B. jararacussu venom, whereas...
Abstract BACKGROUND Nutritional intervention with the use of phytochemicals is an important method for treatment and prevention a metabolic syndrome. The objective this study was to chemically characterize Moro orange juice. influence juice intake on parameters rats that were obese, diabetic or both by means body mass management after activation anthocyanins during refrigerated storage also assessed. RESULTS Juice reversed most abnormalities exhibited obese rats, including reduction...
Industrial and consumer products, such as pesticides, lubricants, cosmetics, can contain perfluorinated compounds (PFCs). Although many short-chain PFCs have been linked to physiological behavioral changes in fish, there are limited data on longer-chain PFCs. The objective of this study was determine the potential impact perfluorotetradecanoic acid (PFTeDA) exposure zebrafish (Danio rerio) during early developmental stages. We measured several endpoints including gene expression,...
