1. Optimization of ultrasound-assisted extraction of turkish propolis and characterization of phenolic profile, antioxidant and antimicrobial activity
Abstract This study aimed to determine optimum conditions of the ultrasound assited extraction (UAS) parameters for different solvent types by using response surface methodology (RSM) and Box- Behnken design. The model parameters namely, time, temperature and ultrasound power significantly affected TPC value of the propolis extract (P < 0.05). The optimum pr

3. Determination of in-vitro phenolics, antioxidant capacity and bio-accessibility of Kombucha tea produced from black carrot varieties grown in Turkey
Abstract Black carrot, which is an economically important product, is produced extensively in Konya and Hatay regions in Turkey. Kombucha tea is a symbiotic system, comprises of bacteria and yeasts cultures called as SCOBY, and produced by fermentation of sugar and tea leaves. Kombucha samples contained black carrot juice in two concentrations (10 and 20%) a

4. Amino acids and antioxidant activities of extracts from wild edible mushrooms from a community forest in the Nasrinual District, Maha Sarakham, Thailand
Abstract Twenty two species of wild edible mushrooms were collected from Nasrinual community forest. The levels of 15 amino acids, antioxidant activity, and γ-aminobutyric acid (GABA) were determined. The 8 essential amino acids were arginine, histidine, isoleucine, leucine, lysine, phenylalanine, threonine, and valine, that they were found in all the mushr

6. Optimizing the supercritical fluid extraction process of bioactive compounds from processed tomato skin by-products
Abstract A supercritical fluid extraction (SC-CO2) was used to extract high-quality oil from tomato skin by-products. The effects of pressure and extraction time on oil yield was investigated in the study. Lycopene and β-carotene content as well as p-coumaric acid, ferulic acid, caffeic acid, chlorogenic acid, vanillic acid, epicatechin, naringenin, catechi

7. [Avaliação morfoquantitativa do coração da cutia (Dasyprocta agouti) e da capivara (Hydrochoerus hydrochaeris)]
RESUMO A cutia (Dasyprocta agouti) e a capivara (Hydrochoerus hydrochaeris) são roedores histricomorfos da fauna brasileira. A anatomia de animais silvestres é essencial para a prática clínico-cirúrgica e programas conservacionistas. Este trabalho objetivou avaliar a morfologia quantitativa do coração da cutia e da capivara. Para isso, foram utilizado

10. Storage of boar semen at 16-18 °C in the long-term commercial extender prepared with deionized water or nanowater
Abstract The aim of this study was to assess the usefulness of nanowater (NW; water declusterized using cold plasma treatment) as a diluent for a commercial boar semen extender during the 15-day storage (Days 1 to 15) at 16-18 °C. Ejaculates collected from 8 boars were subjected to the standard evaluation and then diluted in the extender prepared with deion

11. Effects of Light Quality and Chemical Elicitors on the Growth Parameters and Rosmarinic Acid Content of in vitro Cultures of Hyptis pectinata (L.) Poit.
Hyptis pectinata (L.) Poit is a folk medicinal species in Northeast Brazil. In this work, seedlings of H. pectinata were cultured in vitro under diverse light quality spectra and under the influence of two distinct chemical elicitors, salicylic acid and silver nitrate (SN), at concentrations of 30 and 60 μM. Growth parameters, biomass and rosmarinic acid (R

12. Influência da manta geotêxtil e altura da camada de lodo no desaguamento de lodo anaeróbio em leito de drenagem
RESUMO As estações de tratamento de esgoto (ETEs) geram resíduos, com destaque para o lodo de esgoto, que tem aproximadamente 95% de água e se classifica como resíduo sólido, necessitando de disposição final ambientalmente adequada. Assim, o desaguamento é fundamental no gerenciamento do lodo, já que promove redução de volume. O leito de drenagem
