The optimum concentration of anaesthetic used to facilitate fish handling can be determined based on induction and recovery time, among other factors. This study aimed evaluate the effectiveness essential oil Aloysia triphylla (EOAT) as an in Nile tilapia juveniles. tilapias exemplars were immersed at 0 (control group), 10, 20, 30, 40, 80, 150, 300 450 μL L−1 EOAT sedation, anaesthesia time. stress response was evaluated by determination plasma glucose, cortisol, lactate paraoxonase levels...

We report the optimal concentration of essential oil Lippia alba (EOLA) for induction and recovery anesthesia in Nile tilapia (Oreochromis niloticus) during handling. Groups 10 juveniles were separately subjected to a EOLA: 0 (control group), 10, 20, 50, 100, 200, 300, or 500 µL L-1. The plasma cortisol levels significantly decreased anesthetized fish 4 h after stress glucose increased 1 handling exposed EOLA. Sensory analysis showed that tasters did not detect differences through blind test...

One of the most common complications obesity is peripheral nerve damage, which progresses to sensory neuropathy. Green tea (GT) intake has been associated with weight loss and metabolic biomarkers modulation due its antioxidant properties. The present work characterized effects GT in high-fat diet (HFD)-induced neuropathy investigated mechanisms involved. C57BL/6J male mice were fed an HFD or control diet, vehicle for 16 weeks. Weight, blood glucose, nociceptive thresholds assessed....

Bergenin (1) is a C-glucoside of 4-O-methylgallic acid with known antiarthritic activity attributed to modulation cytokine production. The present study was undertaken evaluate whether 1 has antinociceptive properties in models inflammatory pain and investigate its possible mechanisms action. Pretreatment (12.5–100 mg/kg, ip) produced dose-related inhibition acetic acid-induced writhing mice. Furthermore, treatment (50 100 mg/kg) inhibited both the early late phases formalin test. In...

Sepsis is an illness with a high morbidity for which no effective treatment exists. Its has cost because it usually requires intensive care unit and expensive antibiotics. The present study focus in the production of reactive oxygen species early stages sepsis. This aimed at investigating specie during inflammatory response patients Reactive insoluble myeloperoxidase obtained from fresh whole blood were measured by photon counting chemiluminescence 18 septic 12 healthy individuals.

Graphyne is an allotrope of carbon with excellent mechanical, electrical, and optical properties. The scientific community has been increasingly interested in its characterization computational simulation, using molecular dynamics (MD) simulations density functional theory (DFT). present work presents, for the first time (to authors’ knowledge), a finite element (FE) model to evaluate elastic properties graphyne. After presenting brief literature review on latest developments graphyne...

7-Hydroxycoumarin (umbelliferone, 1), the main metabolite of coumarin, has been reported to produce potent antinociceptive effects in animal models pain. However, biochemical events involved antinociception mediated by 1 are currently not well understood. In present study, mechanisms which exerts its pharmacological actions were investigated. Acute pretreatment mice with produced a long-lasting effect against complete Freund's adjuvant (CFA)-induced hyperalgesia. The subchronic...

A cholesterol-rich nanoemulsion (LDE) that mimics the composition of low-density lipoprotein (LDL) acquires apoE in plasma and is taken-up by cells LDL receptors. In this study, to verify whether free cholesterol (FC) cholesteryl ester (CE) components are differently vessels. LDE labeled with (3)H-cholesterol (14)C-cholesteryl oleate was injected into 20 coronary artery disease patients 24 h before a scheduled myocardial bypass grafting.

Abstract Background The search for sickle cell disease (SCD) prognosis biomarkers is a challenge. These markers identification can help to establish further therapy, later severe clinical complications and with patients follow-up. We attempted study possible involvement of levels high-density lipoprotein cholesterol (HDL-C) in steady-state children SCD, once that this lipid marker has been correlated anti-inflammatory, anti-oxidative, anti-aggregation, anti-coagulant pro-fibrinolytic...

Residents of urban slums are at greater risk for disease than their non-slum dwelling counterparts. We sought to contrast the prevalences selected non-communicable diseases (NCDs) between Brazilian adults living in a slum and general population same city, by comparing age sex-standardized NCDs from 2010 survey Pau da Lima, Salvador Brazil, with national population-based telephone survey. NCD both populations were similar hypertension (23.6% (95% CI 20.9⁻26.4) 22.9% (21.2⁻24.6), respectively)...
