Helicobacter pylori (H. pylori) are a bacterium implicated in the etiology of stomach cancer and ulcers. Epidemiology of the antibiotic resistance of H. pylori appears to be higher. The study was to screen an efficiency substance of Chinese herbs, which could be used in preventing and treating H. pylori diseases. A total of 40 extracted efficiency substances from Chinese herbs were examined and...

it is necessary to determine the amount of chilling requirement of present cultivars and also to produce new low chill cultivars through breeding programs because of the global warming phenomenon and tendency to grow temperate fruit in warm climate. in this study, the amount of chilling requirement in ‘askari’, ‘rotaby’, ‘yaghuty’, ‘rish baba’ and ‘monaga΄ were evaluated. uniform cuttings of me...

Aboveand below-ground clonal growth architecture was compared for two neighbouring patches of Potamogeton perfoliatus L. in Lake Constance, representing typical sparse and dense growth types. A detailed map of individual ramets and their corresponding rhizome network was produced and the seasonal development of ramet sprouting and rhizome growth was reconstructed. Rhizomes extended at rates ran...

Previous studies pointed out that species richness and high density values within the Leguminosae in Brazilian forest fragments affected by fire could be due, at least partially, to the high incidence of root sprouting in this family. However, there are few studies of the factors that induce root sprouting in woody plants after disturbance. We investigated the bud formation on root cuttings, an...

Abstract Rhizome of Polygonatum sibiricum is both a renowned traditional Chinese remedy and commonly consumed delicacy. Due to the escalating demand excessive overexploitation, there has been growing interest in artificial cultivation this plant recent years. To assess therapeutic benefits artificially cultivated P. , it crucial identify classify its phytochemical components, which are primary ...

SUMMARY 1. The development of the ventral root (VR) in Xenopus has been studied by electron microscopy. Total fibre counts, and counts of classes of fibres were made from large photomontages of the whole of VR 9 at x 15000. 2. The total number of fibres in the root shows the same pattern of initial rise, peak, and subsequent decline that previous ventral horn (VH) cell counts had shown, The two...

Background: The aim of this study was to examine the resource allocation among the organs and the leaf morphology of Polygonatum humile. The data were collected from June 2014 to May 2015 in a natural P. humile stand of a temperate forest gap. Results: The dry weight of new rhizome (R0) sharply decreased to the time of new shoot sprouting in next year and was constant for 2 ~ 3 years. However, ...
