RGA and GAI are negative regulators of the gibberellin (GA) signal transduction pathway in Arabidopsis thaliana. These genes may have partially redundant functions because they are highly homologous, and plants containing single null mutations at these loci are phenotypically similar to wild type. Previously, rga loss-of-function mutations were shown to partially suppress defects of the GA-defi...

In this work, a fine-grained structure with a uniform distribution of TiB2 particles and precipitates was achieved in TiB2 particle-reinforced (PR) Al-Zn-Mg-Cu alloys by friction stir processing (FSP). The effects of multi-pass FSP on the microstructure, and TiB2 particle distribution, as well as the microstructural evolution in the following T6 treatment, were investigated by X-ray diffraction...

ETHNOPHARMACOLOGICAL RELEVANCE In traditional Chinese medicines, Cortex Dictamni is prescribed for the treatment of a variety of inflammatory diseases such as acute rheumatoid arthritis, skin inflammation and jaundice. AIM OF THE STUDY This study was designed to investigate the effect of ethanol extract of Cortex Dictamni on treatment of hepatic fibrosis and its possible mechanisms. MATERIA...

Behavior of the xenon dispenser hollow cathode is known to be complex, exhibiting high through-anode ion emission, unusual particle energy distributions, and high plume erosion rates. A flight-type T6 hollow cathode was characterized using several diagnostic methods. Measurements involved a retarding potential analyzer, quadrupole mass spectrometer, and Langmuir probe. Far-field energy, flux, p...

BACKGROUND Several animal studies support the contention that thoracic spinal cord stimulation (SCS) might decrease arterial blood pressure. OBJECTIVE To determine if electrical stimulation of the dorsal spinal cord in humans will lower mean arterial pressure (MAP) and heart rate (HR). DESIGN Case Series METHODS Ten normotensive subjects that were clinically indicated for SCS testing were...
