Longitudinal cross-lagged association between posttraumatic stress disorder, post-traumatic growth, and deliberate rumination among healthcare staff 2 years after the COVID-19 pandemic in Hubei Province, China.

Background: Post-traumatic stress disorder (PTSD) and post-traumatic growth (PTG) are inspiratory areas of psychological research in which deliberate rumination has important implications. However, these relationships have not yet been assessed in the COVID-19 pandemic using longitudinal designs.

Methods: In this study, measures of PTSD, PTG, and deliberate rumination were collected from 2,292 healthcare staff members at two-time points six months apart in 2022-2023 from two general hospitals in Hubei Province, China.

An Ultrahigh-Modulus Hydrogel Electrolyte for Dendrite-Free Zinc Ion Batteries.

Quasi-solid-state aqueous zinc ion batteries suffer from anodic zinc dendrite growth during plating/stripping processes, impeding their commercial application. The inhibition of zinc dendrites by high-modulus electrolytes has been proven to be effective. However, hydrogel electrolytes are difficult to achieve high modulus owing to their inherent high water contents.

The association between perceive social support and post-traumatic stress disorder symptoms among medical staff in Hubei, China: a chain mediating effect of resilience and positive coping.

Background: Evidence suggests that PTSD symptoms following public health emergencies are influenced by many factors. The aim of this study was to investigate the relationship between perceived social support and Post-traumatic stress disorder symptoms and to explore the chain-mediated role of resilience and positive coping style, among medical staff in Hubei Province, China, during a public health emergency.

Methods: Convenience sampling was used to select medical staff from two general hospitals in Hubei Province in July 2022 for this study.

An artificial bone filling material of poly l-lactic acid/collagen/nano-hydroxyapatite microspheres: Preparation and collagen regulation on the property.

Artificial bone materials are in great need due to a lot of bone injuries. Herein, collagen/nano-hydroxyapatite (Col/nHA, C-H) composite nanospheres were obtained by in-situ mineralization, and poly L-lactic acid/collagen/nano-hydroxyapatite (PLLA/Col/nHA, P-C-H) was further prepared by high-speed shear emulsification method. The interfacial properties and structure between PLLA and nHA are regulated by the adhesive property of Col.

Mineralized self-assembled silk fibroin/cellulose interpenetrating network aerogel for bone tissue engineering.

The preparation of bioactive materials with biomolecules as templates to control the nucleation and growth of nano-hydroxyapatite (n-HA) crystals is a vital research field in bone tissue engineering. However, meeting the performance requirements of possessing appropriate surface roughness, high porosity, structural stability, adequate mechanical strength, biodegradability and biocompatibility at the same time is the core issue that restricts the development of these biomimetic materials in biosciences as well as medical clinical translation. In this work, a mineralized self-assembled silk fibroin (SF)/cellulose interpenetrating network composite aerogel (M-S-C) material was prepared by freeze-drying using sol-gel and in situ mineralization strategy.

A new cancellous bone material of silk fibroin/cellulose dual network composite aerogel reinforced by nano-hydroxyapatite filler.

Composites materials comprised of biopolymeric aerogel matrices and inorganic nano-hydroxyapatite (n-HA) fillers have received considerable attention in bone engineering. Although with significant progress in aerogel-based biomaterials, the brittleness and low strengths limit the application. The improvements in toughness and mechanical strength of aerogel-based biomaterials are in great need.
