Advanced manufacturing agglomeration (AMA) plays a significant role in supporting regional development, but few studies have examined it on geographic space. In this paper, the relationship between AMA and economic‒innovative‒social coupling coordination development (EISCCD) was studied spatially at fine-grained scale (500 m × 500 m), taking Liangjiang New Area (LJNA), China, as an example. The results showed that (1) spatial patterns of EISCCD LJNA were similar; (2) among four different...

China’s early achievement of carbon peaking is systematic and pioneering, driving energy economic transformation upgrading as well high-quality development under goal-oriented frameworks. Therefore, based on an extended Solow model, consumption dioxide emissions are incorporated into the model for empirical analysis to explore relationship between sustainable development. The study reveals that elasticity growth relatively significant, while acts a “negative input” growth, with significantly...

Colorectal cancer (CRC) is the third most common type of cancer. MicroRNAs have been reported to participate in progression various cancers. In previous studies, miR-301a-3p expression was shown be upregulated CRC tissues. However, underlying mechanism has not yet elucidated. Herein, level found significantly clinical tissues and cell lines (HT29 SW620). addition, overexpression obviously promoted proliferation, migration invasion, inhibited apoptosis cells. Meanwhile, also enhanced...

Providing satisfactory healthcare services for breast cancer survivors can effectively reduce their burden and the pressure on medical resources. The aim of this study was to explore health care service demands community-dwelling using Kano model.

Introduction The caring behavior of hospice nurses toward patients positively impacts their professional careers and significantly improves the quality services. A positive supportive work environment may protect against negative emotions that affect humanistic care they provide, job satisfaction. This study aimed to explore impact nursing on behavior. We also investigated chain mediating effect psychological capital empathy this relationship among Chinese nurses. Methods Practice...
