An. bras. dermatol; 94 (5), 2019
Abstract Background Rubeosis faciei diabeticorum is a persistent facial erythema in patients with diabetes mellitus. The actual pathogenesis has not been studied. However, it is speculated to be a cutaneous diabetic microangiopathy. Objective Examine the correlation between the severity of facial eryth...

Effect of feeding grape seed Proanthocyanidin extract on production performance, metabolic and anti-oxidative status of dairy cattle

Aims to investigate the effects of grape seed proanthocyanidin extract (GSPE) on production performance, metabolism, and anti-oxidative status of Holstein dairy cattle in early lactation. Forty-eight multiparous Holstein dairy cattle were assigned to four groups (CON, G20, G40 and G80) and supplied with ...

Phenolic compounds from Virola venosa (Myristicaceae) and evaluation of their antioxidant and enzyme inhibition potential

Acta amaz; 49 (1), 2019
Virola venosa, popularly known in Brazil as ucuuba-da-mata, occurs naturally in the Amazon region and has potential to provide useful natural compounds, as already known for other Virola species. Therefore, the objective of this study was to determine the chemical composition of bark and leaf extracts of...

Correlation of the aqueous humor total antioxidant capacity, total oxidant status, and levels of IL-6 and VEGF with diabetic retinopathy status

Arq. bras. oftalmol; 82 (2), 2019
ABSTRACT Purpose: We aimed to compare the aqueous humor total oxidant status, total antioxidant capacity, and levels of interleukin-6 and vascular endothelial growth factor between patients with diabetic retinopathy and controls and to correlate these levels with the DR status. Methods: Patients who un...

The anticonvulsant effects of Ducrosia anethifolia (Boiss) essential oil are produced by its main component alpha-pinene in rats

Arq. neuropsiquiatr; 77 (2), 2019
ABSTRACT Ducrosia anethifolia has been recommended as a remedy for neurological disorders. However, the anticonvulsant effects of D. anethifolia essential oil (DAEO) and its major constituent α-pinene have not yet been clarified. Methods: A rat model of pentylenetetrazole (PTZ)-induced convulsions ...

Photoprotection / photostabilizer potential in a quercetin sunscreens: determination of physical-chemical, safety and efficacy properties

Ultraviolet radiation (UV) is related to the development of skin cancer and photoaging, also produces free radicals or reactive oxygen species (ROS) that cause premature aging. Therefore, sunscreens with extended UV protection capacity have been studied associated with antioxidant compounds. Different co...

Desiccation tolerance in the Antarctic moss Sanionia uncinata

Biol. Res; 52 (), 2019
BACKGROUND: One of the most extreme environments on our planet is the Maritime Antarctic territory, due to its low-water availability, which restricts the development of plants. Sanionia uncinata Hedw. (Amblystegiaceae), the main colonizer of the Maritime Antarctic, has effective mechanisms to tolerate t...

Influence of preparation procedures on the phenolic content, antioxidant and antidiabetic activities of green and black teas

The influence of common tea preparation procedures (temperature, infusion time, consumption time interval and tea bag/loose-leaf) and the type of water used, on the total phenolic content (TPC), the radical scavenging activity and the α-glucosidase inhibitory activity were assessed. Higher TPC and antio...

Antioxidant and cytotoxic properties of protein hydrolysates obtained from enzymatic hydrolysis of Klunzinger's mullet (Liza klunzingeri) muscle
