The Comparison between Spinal Facet Joint Toothed Plate and Traditional Pedicle Screw-rod on Reduction of Thoracolumbar Fracture.

Objective: Thoracolumbar fractures are one of the most common fractures in clinical practice. Surgical intervention is recommended to restore spinal alignment or decompress the nerves when there are unstable fractures or neurological injuries. However, after excessive forward thrust force restoration, facet joint dislocation often occurs between the upper vertebra and the fractured vertebra, which usually leads to unsatisfactory reduction outcomes.

The impact of utilizing oyster shell soil conditioner on the growth of tomato plants and the composition of inter-root soil bacterial communities in an acidic soil environment.

Co-exposure to nanoplastics and acetaminophen causes skeletal dysplasia and behavioral abnormalities in zebrafish.

Nanoplastics (NPs) and acetaminophen (APAP) are thought to be common contaminants and are invariably detected in the environment. Despite the increasing awareness of their toxicity to humans and animals, the embryonic toxicity, skeletal development toxicity, and mechanism of action of their combined exposure have not been clarified. This study was performed to investigate whether combined exposure to NPs and APAP induces abnormal embryonic and skeletal development in zebrafish and to explore the potential toxicological mechanisms.

EFEMP1 binds to STEAP1 to promote osteosarcoma proliferation and invasion via the Wnt/β-catenin and TGF-β/Smad2/3 signal pathways.

Purpose: To investigate the prognostic value and function of six-transmembrane epithelial antigen of prostate 1 (STEAP1) in osteosarcoma and determine whether EFEMP1 mediates its effects.

Methods: IHC (immunohistochemistry)/ICC (immunocytochemistry) in conjunction with RT-qPCR (quantitative real-time polymerase chain reaction) were employed to assess the expression of STEAP1 in paratumoral tissues, osteosarcoma, benign fibrous dysplasia, osteosarcoma cells, normal osteoblastic hFOB cells, as well as various invasive subclones. The association of STEAP1 with outcome was examined with Kaplan-Meier graph among the osteosarcoma population.

STEAP2 promotes osteosarcoma progression by inducing epithelial-mesenchymal transition via the PI3K/AKT/mTOR signaling pathway and is regulated by EFEMP2.

This study was designed to explore the prognostic significance and functionality of STEAP2 (six-transmembrane epithelial antigen of prostate 2) in osteosarcomas and determine whether EFEMP2 (Epidermal growth factor-containing fibulin-like extracellular matrix protein 2) targets STEAP2 to facilitate osteosarcoma cell infiltration and migration. STEAP2 expression in peritumoral tissues, osteosarcoma, benign fibrous dysplasia, osteosarcoma cells, normal osteoblastic hFOB cells, and various invasive subclones was evaluated using IHC, ICC, and qRT-PCR. We also evaluated the association between STEAP2 expression and disease outcome using Kaplan-Meier analyses and then investigated STEAP2 regulation and its functional effects using both and assays.

Novel Therapeutic Savior for Osteosarcoma: The Endorsement of Ferroptosis.

Ferroptosis has recently been discovered as an iron-dependent and non-apoptotic regulated mechanism of cell death. The induction of ferroptosis in tumor cells improves tumor treatment, making it a current research hotspot. Mechanistically, it starts by lipid peroxidation, iron accumulation, reactive oxygen species (ROS) production, and glutathione deprivation, highlighting novel treatment opportunities for many tumors and neurodegenerative disorders.

Intravertebral insertion of interbody fusion cage via transpedicular approach for the treatment of stage III Kümmell disease: a technical note and case presentation.

Background: Kümmell disease usually occurs in the elderly osteoporosis population and develops gradually into symptomatic, progressive kyphosis of the spine. However, current surgical methods to deal with stage III Kümmell disease are less satisfying. The objective of this study was to describe a less invasive technique for treating stage III Kümmell disease.

Effects of Teriparatide versus Salmon Calcitonin Therapy for the Treatment of Osteoporosis in Asia: A Meta-analysis of Randomized Controlled Trials.

Objective: The objective of this meta-analysis was to compare the efficacy and safety of teriparatide versus salmon calcitonin for the treatment of osteoporosis in Asian patients and to investigate whether the results of global studies could be applicable to Asian patients.

Methods: PubMed, OVID, Cochrane Central Register of Controlled Trials (CENTRAL) and EMBASE up to December 2018 were searched. Eligible randomized controlled trials (RCTs) that compared teriparatide versus salmon calcitonin in Asian osteoporosis population were included.

Escin suppresses HMGB1-induced overexpression of aquaporin-1 and increased permeability in endothelial cells.

Escin, a natural triterpene saponin mixture obtained from the horse chestnut tree (Aesculus hippocastanum), has been used for the treatment of chronic venous insufficiency (CVI), hemorrhoids, and edema. However, it is unclear how escin protects against endothelial barrier dysfunction induced by pro-inflammatory high mobility group protein 1 (HMGB1). Here, we report that escin can suppress (a) HMGB1-induced overexpression of the aquaporin-1 (AQP1) water channel in endothelial cells and (b) HMGB1-induced increases in endothelial cell permeability.

Cerebral dopamine neurotrophic factor protects microglia by combining with AKT and by regulating FoxO1/mTOR signaling during neuroinflammation.

Background: The activation of microglia plays a crucial role in neuroinflammation. Previous studies have shown that cerebral dopamine neurotrophic factor (CDNF) has a protective effect on neuroinflammation, but the mechanisms involved have not been fully studied. AKT is a serine-threonine protein kinase widely expressed in mammals through which the downstream pathway FoxO1/mTOR is closely related to cell inflammation, apoptosis, metabolism, etc.

Ferulic acid and PDMS modified medical carbon materials for artificial joint prosthesis.

Medical carbon material has been extensively studied due to their excellent biological and mechanical properties. However, the dissociation of the surface carbon particles greatly limited the application of medical carbon material (MCM). To overcome this defect, we introduced the polydimethylsiloxane, a polymer-coating material (PCM) that possesses acceptable biocompatibility, into medical carbon material to prevent the shedding of carbon debris.
