The study was carried out to investigate the antimicrobial, antioxidant potential and the qualitative and quantitative phytochemical analysis of the bark and leaf of Cocculus laurifolius DC. by using polar and non-polar solvents, i.e. Petroleum ether, Chloroform, Methanol and distilled water. Chloroform bark extracts showed maximum % yield. Antimicrobial activity was determined by using 4 bacte...

in recent years, shallow bark canker of walnut (juglandis regia l.) trees has become fairly widespread in iran. to determine the distribution of the disease in golestan, mazandaran and gilan provinces, from early summer to mid-fall seasons of 2004, more than one hundred bark samples were collected from walnut trees showing symptoms of shallow bark canker. sixty strains of bacteria were isolated...

Quillaia extracts (synonyms: quillaja extracts, bois de Panama, Panama bark extracts, quillai extracts, Quillay bark extracts, soapbark extracts; C.A.S. no. 68990-67-0, INS no. 999) are obtained by aqueous extraction of the milled inner bark or whole wood of Quillaja saponaria Molina (family Rosaceae), which is a large evergreen with shiny, leathery leaves and a thick bark, native to China and ...

Background and Purpose: Oral candidiasis is one of the most common fungal infections in humans. The treatment and prophylaxis of the patients suffering from this infection require the identification of new anti-Candida agents with no side effects or toxicity like medicinal plants. The present study was conducted to compare the antifungal activities of the aqueous, ethanolic, and methanolic extr...

The leguminous tree Sophora japonica contains a family of closely related, but distinct, lectins. Different members of this family are independently expressed in seeds, leaves, and bark (CN Hankins, J Kindinger, LM Shannon 1987 Plant Physiol 83: 825-829; 1988 Plant Physiol 86: 67-10). The inter-, and intracellular distribution of the bark and leaf lectins was studied by indirect postembedding i...

Mass trapping Verbenone flakes Ips lecontei outbreak in southwestern ponderosa pine forests Large scale outbreaks of bark beetles in recent years have severely impacted forest conditions in the western United States. In response to these outbreaks, the USDA Forest Service in cooperation with the Western Forestry Leadership Coalition drafted a report (2002) that called for increased short-and lo...

Two of the common mechanisms regulating G protein-coupled receptor (GPCR) signal transduction are phosphorylation and sequestration (internalization). Agonist-mediated receptor phosphorylation by the b-adrenergic receptor kinase (bARK) facilitates subsequent interaction with an arrestin protein, resulting in receptor desensitization. Studies of the b2-adrenergic receptor (b2AR) receptor in huma...

In a simulation model, the relative advantage of negative versus positive allometry of defense, that is, early versus delayed defensive investment, depends on the forms of the relationships between body size and growth, body size and mortality deterrence, and defense size and mortality deterrence. Positive allometry is favored by strongly sigmoidal growth, a strongly convex body-size/deterrence...
