The aim of this study was the development and characterization of lipid nanocarriers using food grade components for oral delivery of Serenoa repens CO2 extract, namely microemulsions (MEs) and self-microemulsifying drug delivery systems (SMEDDSs) to improve the oral absorption. A commercial blend (CB) containing 320 of S. repens CO2 extract plus the aqueous soluble extracts of nettle root and ...

Prostatic inflammation is widespread in the male population. Two groups of 50 patients each with symptoms of prostatic inflammation and ecocolorDoppler indicative of prostatitis were identified. Both groups were further subdivided into two subgroups (respectively A1, A2, B1, and B2). Group A1 underwent therapy with oral levofloxacin 500 mg daily for 10 days plus co-treatment with oral Serenoa r...

227 The scientists at University of Nebraska-Lincoln, Lincoln, Nebraska, USA reported the production and characteristics of natural cellulose fibres obtained from the leaves and stems of Switchgrass (Panicum virgatum Linn.). The composition, structure and properties of fibres obtained from the leaves and stem of switchgrass have been evaluated in comparison to the common natural cellulose fibre...

Stinging nettle (Urtica dioica) is a plant well known in traditional medicine for its many beneficial properties, but the lack of standardization regarding product to offer consumers limits diffusion. To this end, drying appears be useful technique low-cost that can stored long time, different procedures may give rise end-products very quality as nutraceutical and antioxidant compounds.

Inflammatory joint diseases are characterized by enhanced extracellular matrix degradation which is predominantly mediated by cytokine-stimulated upregulation of matrix metalloproteinase (MMP) expression. Besides tumour necrosis factor-alpha (TNF-alpha), Interleukin-1beta (IL-1beta) produced by articular chondrocytes and synovial macrophages, is the most important cytokine stimulating MMP expre...

BACKGROUND The common nettle (Urtica dioica L.) is co-associated with willows (Salix spp.) in riparian habitats across Europe. We sampled the widespread nettle psyllid, Trioza urticae (Linné, 1758), from Urtica in willow habitats on a megatransect of Europe from the Aegean to the Arctic Ocean. The aim of this study was to use an unusually widespread insect to assess the influence of geographic ...
