Berberis jaeschkeana fruits, source of nutraceutically important polyphenolics were investigated. A total of 32 experimental run were conducted under Plackett-Burman and central composite design. Microwave power, methanol and HCl concentration significantly (p<0.05) affect extraction of polyphenols under linear, quadratic and interactive effect. The model showed good fitness with significant (p<0.05) model F-value and a non-significant lack of fit. Under optimum microwave assisted extraction (MAE) condition the total phenolics, flavonoids, tannins and antioxidant activity were in closed context with predicted values...

Forecasting ecological responses to climate change, invasion, and their interaction must rely on understanding underlying mechanisms. However, such forecasts require extrapolation into new locations and environments. We linked demography and environment using experimental biogeography to forecast invasive and native species' potential ranges under present and future climate in New England, United States to overcome issues of extrapolation in novel environments. We studied two potentially nonequilibrium invasive plants' distributions, Alliaria petiolata (garlic mustard) and Berberis thunbergii (Japanese barberry), each paired with their native ecological analogs to better understand demographic drivers of invasions...

Status epilepticus (SE) is a life-threatening neurologic condition, instigating epileptogenesis to transform normal brain to an epileptic condition. SE is followed by spontaneous recurrent seizures (SRS) and final development of temporal lobe epilepsy (TLE) that is resistant to treatment. Neuroprotective strategies are increasingly put forward as a promising therapy to prevent and/or manage epileptic conditions. In this study, we investigated whether berberis alkaloid, i.e. berberine (BBR), could ameliorate intrahippocampal kainate-induced SE and its consequent epileptogenic process and to explore some underlying mechanisms...

BACKGROUND: Berberis aristata, because of its berberine content, and Monascus purpureus fermented rice, because of the presence of monacolins (naturally derived statins), are widely investigated food-grade ingredients used to formulate cholesterol-lowering supplements. Although they are extensively used, berberine is poorly absorbed and monacolins are poorly chemically characterized, not standardized, and possibly contaminated with toxic compounds. Silymarin is reported to enhance berberine absorption, while Monakopure™-K20 (MK-20) is a highly standardized red yeast rice containing monacolins K and KA in the ratio of 1:1 but not secondary monacolins, dehydromonacolins, or citrinin...

INTRODUCTION: Use of compatible abutments may increase micromovements between the abutments, and the inner part of the implant may increase the stress on marginal bone level. Also micromovement will change the volume of the inner space of the implant-abutment complex. The resulting pumping effect can transport even initially immobile microorganisms from the exterior to the interior and vice versa. OBJECTIVES: The purpose of the study was to evaluate the mechanical comportment of OsseoSpeed™ Tx implants connected with original and compatible abutments in vitro under simulated clinical loading conditions...

Galangin is an active pharmacological ingredient from propolis and Alpinia officinarum Hance, and has been reported to have anti-cancer and antioxidative properties. Berberine, a major component of Berberis vulgaris extract, exhibits potent anti-cancer activities through distinct molecular mechanisms. However, the anticancer effect of galangin in combination with berberine is still unknown. In the present study, we demonstrated that the combination of galangin with berberine synergistically resulted in cell growth inhibition, apoptosis and cell cycle arrest at G2/M phase with the increased intracellular reactive oxygen species (ROS) levels in oesophageal carcinoma cells...

An Ayurvedic polyherbal extract (PHE) comprising six herbs viz. Berberis aristata, Cyperus rotundus, Cedrus deodara, Emblica officinalis, Terminalia chebula and Terminalia bellirica is mentioned as an effective anti-hyperglycemic agent in 'Charaka Samhita', the classical text of Ayurveda. Previously, antidiabetic drug metformin was found to elicit antiaging effects and PHE was also found to exhibit antidiabetic effects in humans. Therefore, we screened it for its in vivo antioxidant antiaging effect on stress and lifespan using human homologous Caenorhabditis elegans model system...
