Identification of keystone taxa in rhizosphere microbial communities using different methods and their effects on compounds of the host Cinnamomum migao.

Exploring keystone taxa affecting microbial community stability and host function is crucial for understanding ecosystem functions. However, identifying keystone taxa from humongous microbial communities remains challenging. We collected 344 rhizosphere and bulk soil samples from the endangered plant C.

Seed Dormancy Release and Germination Requirements of , an Endangered and Rare Woody Plant in Southwest China.

Seed dormancy is a complex adaptive trait of plants that are influenced by several physiological and environmental factors. The endangered plant is also known to exhibit seed dormancy and low germination, which may influence its regeneration; however, these characteristics remain unexplored. To our knowledge, this study is the first to examine the type of dormancy and improve the germination percentage of seeds.

Simulated atmospheric nitrogen deposition inhibited the leaf litter decomposition of Cinnamomum migao H. W. Li in Southwest China.

Atmospheric nitrogen (N) deposition could affect various ecological processes in forest ecosystems, including plant litter decomposition and nutrient cycling. However, the mechanism of underlying litter decomposition and nutrient cycling of Cinnamomum migao under N deposition remains unclear. Therefore, we conducted a simulated N deposition experiment including four onsite treatments to assess the effects of N input on C.

UNBS5162 inhibits colon cancer growth via suppression of PI3K/Akt signaling pathway.

Colon cancer is a common cause of cancer-related death worldwide. However, the underlying mechanism of tumor progression of colon cancer remains far from being elucidated. In the present study, we report the role of UNBS5162 in colon cancer.

Bioinformatic analysis and prediction of the function and regulatory network of long non-coding RNAs in hepatocellular carcinoma.

Computational analysis and bioinformatics have significantly advanced the ability of researchers to process and analyze biological data. Molecular data from human and model organisms may facilitate drug target validation and identification of biomarkers with increased predictive accuracy. The aim of the present study was to investigate the function of long non-coding RNAs (lncRNAs) in hepatocellular carcinoma (HCC) using online databases, and to predict their regulatory mechanism.

Biomechanics of anterior plating failure in treating distractive flexion injury in the caudal subaxial cervical spine.

Background: Operative level is a potential biomechanical risk factor for construct failure during anterior fixation for distractive flexion injury. No biomechanical study of this concept has been reported, although it is important in clinical management.

Methods: To explore the mechanism of this concept, a previously validated three-dimensional C2-T1 finite element model was modified to simulate surgical procedure via the anterior approach for treating single-level distractive flexion injury, from C2-C3 to C7-T1.

Overexpression of Long Non-Coding RNA MEG3 Inhibits Proliferation of Hepatocellular Carcinoma Huh7 Cells via Negative Modulation of miRNA-664.

Evidence is accumulating that long non-coding RNAs (lncRNAs) are involved in human tumorigenesis and dysregulated in many cancers, including hepatocellular carcinoma (HCC). Because lncRNAs can regulate essential pathways that contribute to tumor initiation and progression with their tissue specificity, lncRNAs are valuable biomarkers and therapeutic targets. Maternally expressed gene 3 (MEG3) is a lncRNA overexpressed in HCC cells that inhibits HCC progression, however, the mechanism remains largely unknown.

Stochastic modelling of infectious diseases for heterogeneous populations.

Background: Infectious diseases such as SARS and H1N1 can significantly impact people's lives and cause severe social and economic damages. Recent outbreaks have stressed the urgency of effective research on the dynamics of infectious disease spread. However, it is difficult to predict when and where outbreaks may emerge and how infectious diseases spread because many factors affect their transmission, and some of them may be unknown.

Resection or degeneration of uncovertebral joints altered the segmental kinematics and load-sharing pattern of subaxial cervical spine: A biomechanical investigation using a C2-T1 finite element model.

The uncovertebral joint (UJ) is an important load-bearing structure in the subaxial cervical spine (SCS) and the medial wall of the intervertebral foramen (IVF). To investigate the UJ׳s role in load distribution and transmission under physiological loading, we developed and validated a detailed finite element model (C2-T1). Based on the initial model, two additional models were modified to simulate surgical resection and degeneration of UJs, to evaluate their influence on SCS kinematics and load distribution.

Clonal integration affects growth, photosynthetic efficiency and biomass allocation, but not the competitive ability, of the alien invasive Alternanthera philoxeroides under severe stress.

Background And Aims: Many notorious alien invasive plants are clonal, but little is known about some roles and aspects of clonal integration. Here, the hypothesis is tested that clonal integration affects growth, photosynthetic efficiency, biomass allocation and competitive ability of the exotic invasive weed Alternanthera philoxeroides (Amaranthaceae).

Methods: The apical parts of Alternanthera were grown either with or without the lawn grass Schedonorus phoenix (tall fescue) and their stolon connections to the basal parts grown without competitors were either severed or left intact.

[Clinical observation on effect of electric acupuncture at Sishencong in treating insomnia].

Objective: To evaluate the clinical therapeutic effect of electric acupuncture (EA) at Sishencong (EX-HN 1) on insomnia.

Methods: Two hundred and seventy-six patients were randomly assigned to 2 groups, 138 in each group, the EA group treated with EA at Sishencong, and the control group with oral administration of Tianmeng Capsule. The treatment course for both groups was 3 weeks.

[Growth response of Broussonetia papyrifera seedlings to VA mycorrhizal fungi inoculation].

In an experiment with single inoculation (SI) and co-inoculation (CI) of three VA mycorrhizal fungi, i. e., Glomus mosseea (GM), Glomus versiforme (GV) and Glomus diaphanum (GD), the growth response of Broussonetia papyrifera seedlings in limestone area was studied.

Objective: To observe and evaluate the short-term and long-term curative effects of the synthetic auricular point therapy on the common migraine in attack stage.

Methods: With the study method of randomized controlled trial, 108 cases of common migraine at the attack stage were randomly assigned to a treatment group of 72 cases treated with synthetic auricular point therapy (blood-letting on the ear back, point injection of own blood, pricking ear point), and a control group of 36 cases treated with Western medicine. Their short-term and long-term curative effects were observed and evaluated.
