Evaluation of the cytotoxic and genotoxic potential of Khat (Catha edulis Forsk) extracts on human T lymphoblastoid cell line [PDF]

open access: yes, 2009
This paper reports on an investigation of the cytotoxic and genotoxic potential of khat extract using a human T lymphoblastoid cell line (CEM). Exponentially growing CEM cells were cultured for 12 h in the presence of khat extract (0-2000 μg ml-1 ...

Metabolism of soluble proteins by rumen microorganisms and the influence of condensed tannins on nitrogen solubility and degradation [PDF]

open access: yes, 2004
The amino acid requirements of ruminants are met by two sources; microbes leaving the rumen and dietary protein escaping fermentation in the rumen. Much ruminant research has therefore focused on improving amino acid supply to the duodenum by increasing ...

Exploiting Compositionally Similar Grape Marc Samples to Achieve Gradients of Condensed Tannin and Fatty Acids for Modulating In Vitro Methanogenesis

open access: yesMolecules, 2018
Ruminants produce large amounts of the greenhouse gas, methane, which can be reduced by supplementing feed with products that contain anti-methanogenic compounds, such as the solid winemaking by-product, grape marc.

Evaluation of Aglianico grape skin and seed polyphenols astringency by SDS-PAGE electrophoresis of salivary proteins after the binding reaction [PDF]

open access: yes, 2006
SDS–PAGE electrophoresis and densitometry analysis were carried out to evaluate the reactivity of Aglianico red grape skin and seed polyphenols with human salivary proteins in order to find a method able to assess their astringency.

Modified tannin extracted from black wattle tree as an environmentally friendly antifouling pigment [PDF]

open access: yes, 2015
The use of modified black wattle tannin as an antifouling pigment is reported in this work. A mixture of tannin adsorbed in activated carbon (soluble fraction of tannin) and low soluble fraction of tannin was used as an antifouling pigment.

Changes in oak (Quercus robur) photosynthesis after winter moth (Operophtera brumata) herbivory are not explained by changes in chemical or structural leaf traits [PDF]

open access: yes, 2020
Insect herbivores have the potential to change both physical and chemical traits of their host plant. Although the impacts of herbivores on their hosts have been widely studied, experiments assessing changes in multiple leaf traits or functions ...

Effects of long-term supplementation of chestnut and valonea extracts on methane release, digestibility and nitrogen excretion in sheep

open access: yesAnimal, 2014
The long-term effects of adding chestnut (CHE; Castanea sativa) and valonea (VAL; Quercus valonea) tannin-rich extracts to sheep feed were investigated. In Experiment 1, sheep (65 kg BW) were fed 842 g/day of a ryegrass-based hay.
