Hyperhomocysteinemia Is Associated with Vitamin B-12 Deficiency: A Cross-sectional Study in a Rural, Elderly Population of Shanxi China.

Objectives: To report the association of lifestyle factors and plasma vitamin B-12 with hyperhomocysteinemia in a large sample of men and women living in a region of China where there is an increased risk of NTDs.

Design: Community-based, cross-sectional study of Lvliang City, Shanxi Province, China.

Setting: Hyperhomocysteinemia is an independent risk factor for cardiovascular disease (CVD) and a sensitive marker of vitamin B-12 and folate deficiency.

MicroRNA-140-3p inhibits proliferation, migration and invasion of lung cancer cells by targeting ATP6AP2.

MicroRNAs are small noncoding RNA molecules that regulate gene expression at the post-transcriptional level. Compelling evidence reveals that there is a causative link between microRNAs deregulation and lung cancer development and metastasis. The aim of present study was to explore the function of miR-140-3p in the development and metastasis of lung cancer cell.

Folic acid-conjugated superparamagnetic iron oxide nanoparticles for tumor-targeting MR imaging.

Superparamagnetic iron oxide nanoparticles (SPIONs) have been the subject of extensive research due to their potential biomedical applications. In the present investigation, superparamagnetic FA-PEI-Fe3O4 were successfully prepared and evaluated as a targeted MRI contrast agent. FTIR characteristics, TGA, VSM, and MR imaging confirmed the composition and magnetic properties of the synthesized nanoparticles.

Objectives: This study aimed to describe the nutritional status of elderly people living in a rural area of North China.

Design: Community-based, cross-sectional prevalence survey.

Setting: 3 rural towns of Lvliang City, Shanxi Province, China.
