Willow trees have maintained their place in medicine for many years as they are herbal source of various cures. varieties considered to contain a wide range anti-inflammatory and anti-bacterial species such salicylates flavonoids. The current work is centred on the presence high bioactive pharmaceutical constituents other than salicin flavan-3-ol catechin, salicortin, complex compounds, which c...

Vibrio fetus is significant in the sheep and cattle industries because it causes abortion and infertility. However, little is known of the metabolism of this organism. Smith and Taylor (1919) described V. fetus as being relatively difficult to cultivate immediately after isolation, but after repeated transfers cultivation became less difficult. The organism produced no gas and the reaction rema...

We investigated effects of rehydration and time of sampling on solute accumulation in plants of two greenhouse-grown Populus deltoides Bartr. clones (Ohio Red and Platte) subjected to multiple cycles of water stress. Osmotic potential of leaves at full turgor was measured at predawn on well-watered (control) and water-stressed (conditioned) plants that had been rewatered the previous afternoon....

Thermotoga neapolitana beta-glucosidase (BglA) was subjected to site-directed mutagenesis in an effort to increase its ability to synthesize arbutin derivatives by transglycosylation. The transglycosylation reaction of the wild-type enzyme displays major beta(1,6) and minor beta(1,3) or beta(1,4) regioselectivity. The three mutants, N291T, F412S, and N291T/F412S, increased the ratio of transgly...

1. An organism has been isolated from peat soil which decomposes the specific capsular polysaccharide of Type III Pneumococcus. 2. The isolation has been made possible by the use of a synthetic mineral medium containing the specific polysaccharide as sole source of carbon. By repeated transfers in this medium the potential capacity of the organism to decompose the specific substance has been pr...

The overall objective of this research is to enhance the bioactivity of cellulase enzymes as well as the stability of the enzymes to increase it reusability through immobilization of the enzymes in the microenvironment of porous inorganic-organic hybrid sol-gel polymers. Recently, we have discovered that the microenvironment of these sol-gel polymers markedly increases the bioactivity of immobi...

Over more than five decades, cancer remains a national and international health problem regardless of the discovery of several dozens of novel anticancer drugs (natural and synthetic). Accordingly, screening of natural products for promising anti cancer activity is very initiative field of studies in several countries with diversity of gardenia. Breast and cervix cancers are of the most common ...
