Frictional Properties of Soaps with the Addition of Ground Hazelnut Shells.

The search for new technologies and related new biological materials for use in the cosmetics industry requires many studies and analyses of not only chemical but also physical properties. This study attempts to assess the properties of soap produced with the addition of crushed hazelnut shells. This additive is intended to improve the friction properties of the soap, which in turn enhances the quality of removing impurities from the skin.

Inflammatory macrophages exploited by oral streptococcus increase IL-1B release via NLRP6 inflammasome.

Chronic inflammatory periodontal disease develops in part from the infiltration of a large number of classically activated inflammatory macrophages that release inflammatory cytokines important for disease progression, including inflammasome-dependent interleukin (IL)-1β. Streptococcus gordonii is a normally commensal oral microorganism; while not causative, recent evidence indicates that commensal oral microbes are required for the full development of periodontal disease. We have recently reported that inflammatory macrophages counterintuitively allow for the increased survival of phagocytosed S.

Glucosylceramide synthase inhibitors D-PDMP and D-EtDO-P4 decrease the GM3 ganglioside level, differ in their effects on insulin receptor autophosphorylation but increase Akt1 kinase phosphorylation in human hepatoma HepG2 cells.

Gangliosides function as modulators of several cell growth related receptors. It was shown for caveolin-rich adipocytes, that GM3 ganglioside binds to insulin receptor (IR), dissociates its complex with caveolin, and thus lowers IR autophosphorylation following insulin treatment. We extended those studies into human hepatocyte-derived HepG2 cells, characterized by a high level of IR but low of caveolin.

Assessment of microbiological cleanness of selected medicinal herbs in relations to the level of resource fragmentation.

Herbs are commonly used in the food and pharmaceutical industries. Their vast use is connected with their antibacterial or antioxidising properties, as well as numerous pro-health properties. The aim of the presented research was assessment of the quantitative and qualitative composition of moulds which contaminate samples of dried herbs: Sage (Salvia officinalis L.

Highly selective inhibition of butyrylcholinesterase by a novel melatonin-tacrine heterodimers.

Novel inhibitors of cholinesterases, especially butyrylcholinesterase (BuChE), were obtained by coupling melatonin-tacrine heterodimers via the carbamate bond. Compounds 14a-i possessed potent cholinesterase inhibitory activity (with IC50 values as low as 1.18 nM for acetylcholinesterase (AChE) and 0.
