[Responses of intraspecific and interspecific variations of plant functional traits to grazing in degraded grassland].

Understanding the responses of functional trait variation for grassland plants to grazing disturbance is highly helpful to clarify the community assembly mechanism, functional diversity maintenance, plant adaptation and their strategies. We investigated plant functional traits (plant height, root length, leaf area, root area, leaf dry matter content, shoot dry matter content, root dry matter content, specific leaf area, specific root length and root/ shoot ratio) and the responses of their variation characteristics to grazing disturbance in enclosure and grazing grasslands in Horqin Sandy Land. The results showed that the interspecific variation of functional trait was obviously higher than the intraspecific variation in degraded grassland.

CRISPR-Cas13d Exhibits Robust Antiviral Activity Against Seneca Valley Virus.

In recent years, Seneca Valley virus (SVV) as a newly identified pathogen of porcine vesicular disease spread quickly and has posed a potential threat to the swine industry in several countries resulting in economic losses. Considering the evolution of SVV, attention should be given to controlling SVV epidemics. So far there are no commercial vaccines or drugs available to combat SVV.

Identification of vasospasm biomarkers for cerebral hemorrhage via bio-informatics analysis.

Background: The incidence of cerebral hemorrhage has rapidly increased over time, and vascular dysfunction has a significant influence on the pathogenesis and outcome of these patients. This is also the case for vasospasm in cerebral hemorrhage, but there is no method to assess this. We conducted this study to find molecular biomarkers of vasospasm in cerebral hemorrhage patients.

Diagnosis of Middle Cerebral Artery Stenosis Using Transcranial Doppler Images Based on Convolutional Neural Network.

Background: The purpose of this study was to explore the diagnostic value of convolutional neural networks (CNNs) in middle cerebral artery (MCA) stenosis by analyzing transcranial Doppler (TCD) images.

Methods: Overall, 278 patients who underwent cerebral vascular TCD and cerebral angiography were enrolled and classified into stenosis and non-stenosis groups based on cerebral angiography findings. Manual measurements were performed on TCD images.

[Spatial distribution pattern and allometric growth of three common species on moving sand dunes in Horqin Sandy Land, China].

Research on fine scale pattern and characteristics of allometric growth could contribute to better understanding plants' adaptation in moving sandy dunes. The abundance, height and biomass of 3 species Agriophilum aquarrosum, Corispermum candelabrum and Setaria viridis in twenty-eight 1 m x 1 m quadrats of Horqin Sandy Land were identified, mapped and described. The nearest neighbor method and O-ring O(r) function analysis were applied to analyze the spatial patterns.

[Diagnostic value of 64-slice spiral computed tomographic angiography in vertebral artery stenosis: a meta-analysis].

Objective: To evaluate the diagnostic value of 64-slice spiral computed tomographic angiography (CTA) in vertebral artery stenosis through a meta-analysis of the relevant data.

Methods: A database search of Cochrane Library, PubMed, EBSCO, CBM-disc and CNKI was performed to identify the relevant English and Chinese language articles with such keywords as 64-slice computer tomography, angiography and vertebral artery stenosis. Quality evaluation, heterogeneity test and sensitivity and specificity to the qualified original data were conducted.
