Evaluation of Dunaliella salina growth and corresponding β-carotene production in tubular photobioreactor

Microalgae, photosynthetic microorganisms, are rich in lipids, polyunsaturated fatty acids, carbohydrates, proteins, vitamins, as well as carotenoids, which are antioxidants that may protect human body from various diseases including obesity, cardiovascular disease, vision-related diseases such as macula...

Carotenoid production in sugarcane juice and synthetic media supplemented with nutrients by Rhodotorula rubra l02

Braz. j. microbiol; 49 (4), 2018
ABSTRACT In order for the use of biological carotenoids to become feasible, it is necessary to have adequate low cost sources and improved methods of cultivation. The aim of this study was to evaluate the effect of supplementation with nitrogen, phosphorus, zinc, and magnesium, on the biomass and caroten...

Hydrolytic efficiency and isomerization during de-esterification of natural astaxanthin esters by saponification and enzymolysis

Background: Astaxanthin from natural sources is typically esterified with fatty acids; hence, it must be hydrolyzed to remove esters before identification and quantification by conventional HPLC. Alkaline-catalyzed saponification and enzyme-catalyzed enzymolysis are the most commonly used de-esterificati...

Molecular cloning and characterisation of scavenger receptor class B in pearl oyster Pinctada fuctada martensii

Background: Molluscs can accumulate carotenoids in their body tissues by predominantly feeding on aquatic plant sources. Carotenoid transport and absorption are determined by the regulation of various proteins such as Scavenger receptor class B(SR-BI). We report the identification and characterisation of...

Topical action of Buriti oil (Mauritia flexuosa L) in myositis induced in rats

Acta cir. bras; 32 (11), 2017
Abstract Purpose: To analyze the topical effects of Buriti oil (Mauritia flexuosa L.) in induced myositis in rats. Methods: Thirty six male rats divided into three groups: Control group (C), induced myositis group (MI) and induced myositis group reated with Mauritia flexuosa L. (MT). After inducing my...

Modificaciones en el nivel de anión superóxido en leche materna, según la ingesta de flavonoides y carotenoides

Resumen: Objetivo: Asociar la ingesta de flavonoides y carotenoides con el nivel en leche materna del anión superóxido, como marcador de estrés oxidativo. Material y métodos: Durante el periodo 2013-2015 se estudió a 100 mujeres lactantes de Córdoba (Argentina), dentro los primeros seis meses p...

Essential oil composition, carotenoid profile, antioxidant and antimicrobial activities of the parasitic plant Cuscuta mitraeformis

The chemical composition of the essential oil and carotenoid content of the parasitic plant Cuscuta mitraeformis are described for the first time. The essential oil was analyzed by GC-FID and GC-MS revealing nonanal (24.6%) as the main constituent followed by thymol (16.5%) and eugenol (7.5%). The total ...

Cardioprotective Effect of Crocin Combined with Voluntary Exercise in Rat: Role of Mir-126 and Mir-210 in Heart Angiogenesis

Arq. bras. cardiol; 109 (1), 2017
Abstract Background: Crocin is reported to have a wide range of biological activities such as cardiovascular protection. Recent epidemiologic studies have shown that exercise reduces cardiovascular morbidity and mortality in the general population. Objective: The aim of this study was to evaluate the e...

Lycopene and resveratrol pretreatment did not interfere with the liver of hepatectomized rats

Acta cir. bras; 32 (3), 2017
Abstract Purpose: To investigate the effects of lycopene and resveratrol pretreatment on hepatic hyperplasia in partially hepatectomized rats. Methods: The lycopene group and the resveratrol group received 40 mg/kg/day of lycopene or resveratrol, respectively (dissolved in olive oil or in saline soluti...

Intake of oral photoprotectors by postmen in Porto Alegre

Clin. biomed. res; 37 (3), 2017
Introduction: Postmen are daily exposed to high levels of solar radiation, and lack of protection can result in many health damages. The present study aimed to identify cutaneous phototypes and evaluate the intake of oral photoprotectors by postmen. Methods: Cross-sectional study, carried out from August...
