The use of dexmedetomidine and depth of anaesthesia may influence POD. This study aims to determine the effects of dexmedetomidine infusion versus normal saline placebo during light versus deep anaesthesia on POD among elderly patients undergoing major non-cardiac surgery.

Transplantation of human umbilical cord-derived mesenchymal stem cells improves age-related ovarian functional decline via regulating the local renin-angiotensin system on inflammation and oxidative stress.

Background: Age-related reproductive aging is a natural and irreversible physiological process, and delaying childbearing is increasingly common all over the world. Transplantation of mesenchymal stem cells (MSCs) is considered a new and effective therapy to restore ovarian function, but the relevant mechanisms remain unclear. Recently, it has been found that there is a local Renin-angiotensin system (RAS) in human ovary and it plays a key role.

Preliminary exploration of the biomechanical properties of three novel cervical porous fusion cages using a finite element study.

Background: Porous cages are considered a promising alternative to high-density cages because their interconnectivity favours bony ingrowth and appropriate stiffness tuning reduces stress shielding and the risk of cage subsidence.

Methods: This study proposes three approaches that combine macroscopic topology optimization and micropore design to establish three new types of porous cages by integrating lattices (gyroid, Schwarz, body-centred cubic) with the optimized cage frame. Using these three porous cages along with traditional high-density cages, four ACDF surgical models were developed to compare the mechanical properties of facet articular cartilage, discs, cortical bone, and cages under specific loads.

Role and mechanism of miR-211 in human cancer.

MircoRNA (miRNA), which are a group of small, and highly conserved non-coding RNA consisting of 18-25 nucleotides, can modulate gene expression at post-transcriptional level, through complementary binding to the 3'-untranslated region (3'-UTR) of numerous target genes. Emerging evidence indicates that miRNAs play critical roles in tumorigenesis and progression of cancer. Among them, miR-211 has been extensively studied in multiple cancers.
