Effects of simulated warming on content, fractions and chemical structure of soil organic carbon:Progress and prospects.

Soil organic carbon (SOC) represents the largest terrestrial organic carbon pool and plays an important role in mitigating global climate change. Warming can change the stabilization process and the balance of inputs and outputs of the SOC pool, thereby affecting the content, fraction, and chemical structure of SOC. It has become a research hotspot to reveal the mechanisms underlying the effects of warming on SOC stability by analyzing the fraction and molecular structure of C.

Increased activation of the caudate nucleus and parahippocampal gyrus in Parkinson's disease patients with dysphagia after repetitive transcranial magnetic stimulation: a case-control study.

Repetitive transcranial magnetic stimulation (rTMS) has been shown to effectively improve impaired swallowing in Parkinson's disease (PD) patients with dysphagia. However, little is known about how rTMS affects the corresponding brain regions in this patient group. In this case-control study, we examined data from 38 PD patients with dysphagia who received treatment at Beijing Rehabilitation Medicine Academy, Capital Medical University.

[Spatial and temporal responses of habitat quality to urbanization: A case study of Changchun City, Jilin Province, China].

Habitat quality is an important index to evaluate regional ecological security. Revealing its spatial and temporal responses to urbanization is conducive to the in-depth implementation of new urbanization. Based on land use data, we analyzed the spatio-temporal characteristics of Changchun's landscape pattern, habitat quality and its sample zone from the grid scale with comprehensive utilization of spatial analysis and ecological model analysis.

Prevalence of dermatologic manifestations and metabolic biomarkers in women with polycystic ovary syndrome in north China.

Background: Cutaneous features of hyperandrogenism in polycystic ovary syndrome (PCOS) include acne, hirsutism, seborrhea, androgenic alopecia (AGA), and acanthosis nigricans (AN). However, the relationships have not been well known broadly in terms of clinical hyperandrogenism and biochemical markers.

Objectives: The aim of this study was to investigate biochemical and metabolic parameters in relation to cutaneous characters women in with and without PCOS.

Immunogenicity and Protective Efficacy of a Fusion Protein Tuberculosis Vaccine Combining Five Esx Family Proteins.

One strategy to develop the next generation of tuberculosis vaccines is to construct subunit vaccines based on T cell antigens. In this study, we have evaluated the vaccine potential of a fusion protein combining EsxB, EsxD, EsxG, EsxU, and EsxM of (). This recombinant protein, named BM, was expressed in and purified from .

Variable Virulence and Efficacy of BCG Vaccine Strains in Mice and Correlation With Genome Polymorphisms.

Bacille Calmette-Guérin (BCG), an attenuated strain of Mycobacterium bovis, is the only vaccine available for tuberculosis (TB) control. However, BCG is not an ideal vaccine and has two major limitations: BCG exhibits highly variable effectiveness against the development of TB both in pediatric and adult populations and can cause disseminated BCG disease in immunocompromised individuals. BCG comprises a number of substrains that are genetically distinct.
