Carbon nanotubes (CNTs) can support the building of flexible and porous scaffolds for bone regeneration. Various studies have looked at the mixing of CNTs with hydroxyapaptite for the formulation of bone implants. In the present work, we report the one step preparation and characterisation of chitosan/hydroxyapatite/CNTs composite materials obtained by wet precipitation of hydroxyapatite (HA) in the presence of chitosan or its amphiphilic derivative N-octyl-O-sulphate chitosan and CNTs. The in situ precipitation of HA assured inclusion of the polysaccharide and the CNTs in the HA structure and provided materials with the ability to control the release of different model drugs.

Background: Post-hepatectomy liver failure(PHLF) is a leading cause of postoperative mortality after liver surgery. Due to its significant impact, it is imperative to understand the risk stratification and preventative strategies for PHLF. The main objective of this review is to highlight the role of these strategies in a timeline centered way around curative resection. Data sources: This review includes studies on both humans and animals, where they addressed PHLF. A literature search was conducted across the Cochrane Library, Embase, MEDLINE/Pub Med, and Web of Knowledge electronic databases for English language studies published between July 1997 and June 2020. Studies presented in other languages were equally considered. The quality of included publications was assessed using Downs and Black’s checklist. The results were presented in qualitative summaries owing to the lack of studies qualifying for quantitative analysis. Results: This systematic review with 245 studies, provides insight into the current prediction, prevention, diagnosis, and management options for PHLF. This review highlighted that liver volume manipulation is the most frequently studied preventive measure against PHLF in clinical practice, with modest improvement in the treatment strategies over the past decade. Conclusions: Remnant liver volume manipulation is the most consistent preventive measure against PHLF.

Cervical spinal cord injury （SCI） results in partial to full paralysis of the upper and lower extrem- ities. Traditional primary endpoints for acute SCI clinical trials are too broad to assess functional recovery in cervical subjects, raising the possibility of false positive outcomes in trials for cervical SCI. Endpoints focused on the recovery of hand and arm control （e.g., upper extremity motor score, motor level change） show the most potential for use as primary outcomes in upcoming trials of cervical SCI. As the field moves forward, the most reliable way to ensure meaningful clinical testing in cervical subjects may be the development of a composite primary endpoint that measures both neurological recovery and functional improvement.
