the presence of tribolium castaneum (herbst) in a stored food results in contamination and substantial economic damage due to loss of the products and a decrease in nutritional value. this study was conducted to determine the pesticidal and pest repellent activities of roots of laportea crenulata gaud. against t. castaneum. pesticidal activity was determined using surface film method, whereas, ...

BACKGROUND There has been great interest in improving the efficacy of nonablative technologies by combining them during facial skin rejuvenation. The purpose of this study was to determine whether the addition of topical polyphenolic antioxidants to an intense pulsed light (IPL) treatment regimen augmented the effects of facial IPL treatments. METHODS Thirty female volunteers, ages 34-52, wit...

BACKGROUND & OBJECTIVES The role of oxidative stress in the development of diabetes mellitus and its vascular complications are extensively studied. Hyperglycaemia causes oxidative damage by generation of reactive oxygen species and results in the development of complications. The present study was undertaken with the objective of exploring the anti-hyperglycaemic potential of polyphenolic enri...

The conference “Results and prospects of development of new polyphenolic drugs for cancer patients” took place at the N.N. Petrov National Medical Research Center of Oncology (PNMRCO) on May 31, 2017, and gathered researchers involved in development and evaluation of medicinal products based on the novel lignin-derived soluble polyphenolic polymer BP-Cx-1. BP-Cx-1 is the platform for a portfoli...

ConspectusBioadhesives are important for the future of medicine in their roles wound closure and as measures to enhance healing. These adhesives more effective less invasive than conventional methods, such surgical sutures or staples. Adhesive substances based on naturally occurring biological materials from living organisms harness phenolic compounds attachment wet surfaces. For example, plant...

The non-extractable fraction of many fruit and vegetables contains putatively bioactive polyphenolic compounds that, in most cases, have not been well characterised structurally. Non-extractable proanthocyanidins (NEPA) of a polymeric nature are part of the dietary fibre fraction of food. Using liquid chromatography coupled to a mass spectrometer equipped with an electrospray ionisation chamber...

In this study, the antioxidative fraction of white mulberry (Morus alba) was found to have an apotogenic effect on Ehrlich's ascites carcinoma cell-induced mice (EAC mice) that correlate with upregulated p53 and downregulated NFκB signaling. The antioxidant activities and polyphenolic contents of various mulberry fractions were evaluated by spectrophotometry and the ethyl acetate fraction (EAF)...

In order to validate the Bumelia sartorum Mart., Sapotaceae, traditional use for infection diseases, this study evaluates the antibacterial activity of the stem bark fractions against methicillin-sensitive (MSSA) and methicillin-resistant (MRSA) Staphylococcus aureus strains by using the agar dilution method and reported as MIC (minimal inhibitory concentration). In addition, the DPPH scavengin...
