Neural impairments accompanying chronic obstructive pulmonary disease (COPD) have received growing research attention. Previous neuroimaging studies exclusively used volumetric methods to measure cortical volume as a whole rather than focusing on anatomical and neuropathological distinct indices. Here we decomposed the cortical architecture into cortical(More)
Gibberellins (GAs) are endogenous hormones that play an important role in regulating plant stature by increasing cell division and elongation in stem internodes. The GA2-oxidase gene from Arabidopsis thaliana (AtGA2ox8) was introduced into Brassica napus L. by Agrobacterium-mediated floral-dip transformation with the aim of decreasing the amount of(More)
PROPOSE To design a set of brain templates for postnatal piglet brains based on high-resolution T1-weighted imaging for voxel-based morphometric analysis. MATERIALS AND METHODS Using a 3.0 T magnetic resonance (MR) scanner, a population-based whole brain template was developed by averaging forty T1 images in the brains of postnatal piglets at 38 days of(More)
OBJECTIVES The irreversible airflow limitation characterised by chronic obstructive pulmonary disease (COPD) causes a decrease in the oxygen supply to the brain. The aim of the present study was to investigate brain structural damage in COPD. DESIGN Retrospective case-control study. Patients with COPD and healthy volunteers were recruited. The two groups(More)
The aim of the present study was to investigate cerebral microstructural alterations after single short-term mountain climbing. Voxel-based morphometry (VBM) analysis of gray matter (GM) and white matter (WM) volumes and Tract-Based Spatial Statistics (TBSS) analysis of WM fractional anisotropy (FA) based on MRI images were carried out on 14 mountaineers(More)
The aim of this study was to investigate brain structural alterations in adult immigrants who adapted to high altitude (HA). Voxel-based morphometry analysis of gray matter (GM) volumes, surface-based analysis of cortical thickness, and Tract-Based Spatial Statistics analysis of white matter fractional anisotropy (FA) based on MRI images were conducted on(More)
Glutamate dehydrogenase (GDH) tends to have a lower affinity for ammonium than glutamine synthetase (GS) in higher plants. Consequently, nitrogen is mostly assimilated as ammonium by the GS/glutamate synthase pathway which requires 2-oxoglutarate (2-OG) as carbon skeletons. In contrast, the NADP(H)-dependent GDH in fungi has a higher affinity for ammonium(More)
Transcription factors (TF) play important roles in plant growth and development, which determine crop productivity , quality, and stress tolerance. However, the basic mechanism governing transcription regulation by TF remains largely unclear in plants. It is well known that TF proteins contain at least two functional domains, the DNA-binding domain and the(More)
The full-length cDNA encoding a glutamate dehydrogenase (GDH) which catalyzes the reaction of reductive amination of α-oxoglutarate (α-OG) to glutamate (the anabolic activity) and the reverse reaction of oxidative deamination of glutamate (the catabolic activity) was isolated from Sclerotinia sclerotiorum, we designated it as SsGDH. Bioinformatics analysis(More)
Heterologous expression of a fungal NADP(H)-GDH gene ( MgGDH ) from Magnaporthe grisea can improve dehydration stress tolerance in rice by preventing toxic accumulation of ammonium. Glutamate dehydrogenase (GDH; EC and EC may act as a stress-responsive enzyme in detoxification of high intracellular ammonia and production of glutamate for(More)
