Induced circular dichroism of the interaction between pinacyanol and algal alginates.

The interaction between pinacyanol chloride and sodium alginate or guluronate-rich alginate is found to effect profound changes in the visible absorbance and circular dichroism spectra. Two different types of aggregates are observed depending on the relative dye/alginate concentrations. With a dye/alginate ratio at 1:1, a complex is deduced based on an analysis of Job's method and conductometric titrations.

Chemopreventive effect of raw and cooked lentils (Lens culinaris L) and soybeans (Glycine max) against azoxymethane-induced aberrant crypt foci.

Although lentils (Lens culinaris L) contain several bioactive compounds that have been linked to the prevention of cancer, the in vivo chemopreventive ability of lentils against chemically induced colorectal cancer has not been examined. Our present study examined the hypothesis that lentils could suppress the early carcinogenesis in vivo by virtue of their bioactive micro- and macroconstituents and that culinary thermal treatment could affect their chemopreventive potential. To accomplish this goal, we used raw whole lentils (RWL), raw split lentils (RSL), cooked whole lentils (CWL), and cooked split lentils (CSL).

A new herbal combination, Etana, for enhancing erectile function: an efficacy and safety study in animals.

We present herein a new herbal combination called Etana that is composed of five herbal extracts including Panax quinquelotius (Ginseng), Eurycoma longifolia (Tongkat Ali), Epimedium grandiflorum (Horny goat weed), Centella asiatica (Gotu Kola) and flower pollen extracts. Most of the above-mentioned extracts have a long historical and traditional use for erectile dysfunction (ED). On the basis of the mechanism of action of each of the above, a combination is introduced to overcome several physiological or induced factors of ED.

Cinchonain Ib isolated from Eriobotrya japonica induces insulin secretion in vitro and in vivo.

Aims Of The Study: Eriobotrya japonica leaves had been used traditionally for the treatment of diabetes mellitus by immersing the dried leaves in a hot water drink. Few studies have shown the hypoglycemic effect of Eriobotrya japonica using crude alcoholic extract and isolated methanolic compounds. These studies proposed that the mechanism of action could be by stimulating the beta-islets of Langerhans to secrete insulin, however with no scientific evidence.

Epicatechin suppresses IL-6, IL-8 and enhances IL-10 production with NF-kappaB nuclear translocation in whole blood stimulated system.

Objectives: Cytokines induce the balance between inflammatory versus regulatory or antibody mediated reactions. So modulating the release of cytokines or inducing them by immunomodulating agents is an attractive mode for treating or help in treating several diseases such as autoimmune diseases. Eriobotrya japonica is a plant that is traditionally thought to have anti-inflammatory activities.

The influence of using Jordanian natural zeolite on the adsorption, physical, and mechanical properties of geopolymers products.

Geopolymers consist of an amorphous, three-dimensional structure resulting from the polymerization of aluminosilicate monomers that result from dissolution of kaolin in an alkaline solution at temperatures around 80 degrees C. One potential use of geopolymers is as Portland cement replacement. It will be of great importance to provide a geopolymer with suitable mechanical properties for the purpose of water storage and high adsorption capacity towards pollutants.

Microemulsions are membrane-active, antimicrobial, self-preserving systems.

Microemulsions are physically stable oil/water systems that have potential use as delivery systems for many pharmaceuticals which are normally of limited use due to their hydrophobicity, toxicity or inability to access the site of action. It has been suggested that microemulsions are self-preserving antimicrobials in their own right, although there is little evidence to support this. In this experiment, microemulsions of various compositions were formulated and tested for their stability and antimicrobial action.
