Citrate Improves Biomimetic Mineralization Induced by Polyelectrolyte-Cation Complexes Using PAsp-Ca&Mg Complexes.

Magnesium ions are highly enriched in early stage of biological mineralization of hard tissues. Paradoxically, hydroxyapatite (HAp) crystallization is inhibited significantly by high concentration of magnesium ions. The mechanism to regulate magnesium-doped biomimetic mineralization of collagen fibrils has never been fully elucidated.

Anxiety, depression and post-traumatic stress disorder and related factors among Chinese population during the COVID-19 pandemic: A cross-sectional study.

The sudden outbreak of coronavirus disease 2019 (COVID-19) has deep and wide negative mental impacts on the public, and studies on the impact of COVID-19 on social and mental well-being are necessary.

Clinical nurses' nasogastric feeding practices in adults: a multicenter cross-sectional survey in China.

Objective: We aimed to investigate practices of nasogastric tube (NGT) intubation and feeding for adults by clinical nurses in China.

Methods: A self-designed and validated questionnaire comprising 30 questions was distributed to 560 clinical nurses in three comprehensive hospitals of Xiamen, China. The questionnaire covered participants' demographic characteristics, NGT placement, administration of enteral nutrition (EN), and monitoring or management of feeding intolerance.

[Survey of the current situation on clinical application of root canal treatments in Zhejiang province].

Purpose: To investigate the present situation of root canal treatment (RCT) applied by the endodontists in the major hospitals of Zhejiang province.

Methods: Dentists in different hospitals were asked to fill in the questionnaire, which included the methods and factors of the first-choice treatment of endodontic diseases, instruments and materials used in RCT. The data were analysed by descriptive analysis and Mann-Whiteney U test using SPSS12.
