TL;DR: Results manifested that natural product tannic acid could serve as a potentially effective candidate for development of novel strategies to treat methicillin-resistant S. aureus infections.

TL;DR: The purpose of this study has been to produce single-cell protein (SCP) from mixtures of food waste using Saccharomyces cerevisiae, and the main fermentation test was carried out using a 25 l bioreactor.

TL;DR: Two EO–EO and three EO-chlorhexidine associations gave interesting results as potential constituents of mouthwashes, especially for the contribution of oxygenated monoterpenes, including menthol, thymol and carvacrol.

TL;DR: Boiling water was the best extraction solvent referring to polyphenols from chestnut shells and burs, whereas the most efficient for leaves resulted 60% ethanol at room temperature, and flavonoids, tannins and antioxidant activity were assessed on the best extract obtained from each chestnut by-product.

TL;DR: In this article, the authors evaluated organosulphur compounds in Allium vegetables, including garlic, elephant garlic and onion, using high-performance liquid chromatography and found that there was a close relationship between antioxidant capacity and organophur compounds.

TL;DR: It was found that the calculated biodegradability ratio (COD/BOD5) of the residual bath of dyeing wool and silk with red cabbage extract are lower than 1.5 which means that these baths areBiodegradable.

TL;DR: The results obtained in this study suggest an advisable containment of the sources of pollution and further studies on the closed-loop farming of bluefin tuna, in order to ensure the product safety.

TL;DR: There was no significant difference between the fatty acid contents of the oils obtained by the supercritical and solvent extraction techniques, and the model had a good agreement with the experimental data.

TL;DR: This review supplies an overview of Harmful Algal Blooms, and, in particular, the major consequences of HABs on human health are described.

TL;DR: Trichosides A and B, new withanolide glucosides, have been isolated from the n-butanolic fraction of the 75% methanolic extract of aerial parts of Tricholepis eburnea through spectroscopic analysis and acid hydrolysis.

TL;DR: The obtained results indicate that non-toxic extract from S. officinale root has strong antioxidant potential and a beneficial effect on human skin fibroblasts.

TL;DR: Chemically structural determination showed that ulvan from U. reticulata showed high antimicrobial activity, with inhibition zone diameter of 20 mm against Enterobacter cloace and 18 mm against Escherichia coli.

TL;DR: A novel anthraquinone, 2-(dimethoxymethyl)-1-hydroxyanthracene-9,10-dione, together with nine known compounds, were isolated from the fermentation of Aspergillus versicolor derived from deep sea sediment indicating its usefulness as antimicrobial agent.

TL;DR: The results suggest that certain molecular characteristics are important for the antifungal action of C. albicans strains and that the screened compounds exhibited different levels of activity depending on structural variation.

TL;DR: Investigation of the potential use of Tamarix articulata, quercetin and epigallocatechin gallate in HCC and how these phytochemicals could epigenetically modulate the IGF axis using their impact on miR-1275 found them to have important implications for HCC molecular-targeted therapy.

TL;DR: The virtual utilisation of bio/chemo informatics tools as a reliable and economic alternative to the exhausting and resources-consuming wet-lab experimentation is introduced.

TL;DR: The study showed the possibility of increasing the astaxanthin productivity from X. dendrorhous in a batch fermentative process under continuous illumination and provided useful information about the possible use of this waste material for carotenogenesis fromX.

TL;DR: The results indicated that the essential oil of A. dubia had potential to be developed into natural insecticides for controlling stored product pests.

TL;DR: The present review gives an overview of the ethnobotany, phytochemistry and pharmacology of the Cedrus genus, e.g. cytotoxic, spasmolytic immunomodulatory, antiallergic, anti-inflammatory and analgesic activities.

TL;DR: A new phthalide derivative, xylarphthalide A, along with two known compounds, were isolated from the endophytic fungus Xylaria sp.

TL;DR: Both flavonoids were evaluated for in vitro anticoagulation activities and both had obvious effect in increasing prothrombin time.

TL;DR: Three new polyketides named trichbenzoisochromen A, 5,7-dihydroxy-3-methyl -2-(2-oxopropyl)naphthalene- 1,4-dione and 7-acetyl-1,3,6-trihydroxyanthracene-9,10- dione together with six known compounds were isolated from a sponge-derived fungus Trichoderma sp.

TL;DR: The appreciable amount of phenolic compounds and biological activities in the aqueous extracts of N. cadamba fruits suggests it's potential application as natural preservative.

TL;DR: The predominance and continued presence of o-cymene makes this fennel oil a rather unique chemotype and an evident correlation between the antifungal activity and phenological stage is demonstrated.

TL;DR: The presence of iridoids and phenyl-ethanoid glycosides has a chemotaxonomic relevance and results to be in perfect accordance with the current botanical classification of the species, providing a phytochemical rationale for the use of this particular plant in the ethno-pharmacological field.

TL;DR: Chemical examination of Chinese mangrove Rhizophora mucronata endophytic Pestalotiopsis sp.

TL;DR: The product exerted an antibacterial action in vitro and in vivo, exhibiting a positive action in the control of dental plaque and a similar PHP index to chlorhexidine alone.

TL;DR: An unusual austinoid, 1,2-dehydro-terredehydroaustin, together with two known meroterpenoids were isolated from the mangrove endophytic fungus Aspergillus terreus and exhibited weak inhibition effect against the production of nitric oxide in lipopolysaccharide-induced RAW 246.7 mouse macrophages.
