Article Synopsis
- The study highlights the importance of spatially separating dopants to improve the lifespan of nanoribbon p-n junctions, which are typically costly to create using van der Waals heterostructures.
- Using atomistic quantum mechanical simulations, researchers found that bending nanoribbons alters where dopants preferentially locate, depending on their atomic sizes.
- Larger dopants tend to cluster at the outer edges on the tensile side, while smaller ones prefer the inner edges on the compressive side, allowing for better spatial separation of n-type and p-type dopants in a more cost-effective way.
Osteoblast-mediated bone formation is a complex process involving various pathways and regulatory factors, including cytokines, growth factors, and hormones. Investigating the regulatory mechanisms behind osteoblast differentiation is important for bone regeneration therapy. miRNAs are known as important regulators, not only in a variety of cellular processes, but also in the pathogenesis of bone diseases.

Methods: Pubmed database (from 1968 to March 2014), Cochrane library and CNKI database (from 1998 to March 2014) were searched. Case-control study on minimally invasive percutaneous plate osteosynthesis (MIPPO) or open reduction and internal fixation (ORIF) for distal tibial fractures in adults were chosen,and postoperative infection, operative time, blood loss, fracture nonunion rate, delayed union,fracture malunion rate were seen as evaluation index for meta analysis.
Objective: To explore the surgical technique and mid-term results of rotational acetabular osteotomy for early -stage osteoarthritis secondary to acetabular dysplasia.
Methods: Rotational acetabular osteotomies were performed on 14 hips of 12 patients from May 2000 to May 2006 and the patients followed up. All patients were female and their average age was 28.
Objective: To evaluate the early and middle-term results of in situ single screw fixation and subtrochanteric osteotomy of the femur with external fixator for slipped capital femoral epiphysis (SCFE).
Methods: From June 1998 to July 2008, 11 patients (seven male [eight hips] and four female [four hips]) of average age 14.3 years (range, 9-18 years) were treated in our hospital.
Synchrotron radiation light is 1 of 4 artificial light sources, the others being electric light, X-ray, and laser. Phase-contrast imaging with hard X-ray has achieved wide application in many scientific fields, such as biomedicine and material science. This article compares the effectiveness of nanohydroxyapatite/collagen (nHAC) and autologous mesenchymal stem cell for the repair of defects in a rabbit model with osteonecrosis of the femoral head under the monitoring of phase-contrast imaging with synchrotron hard X-ray.

Objective: To evaluate the effectiveness of autologous adipose derived mesenchymal stem cells (ADSCs) transduced by adenovirus-mediated human transforming growth factor 2 (Ad-hTGF-beta2) gene in the repair of articular cartilage defects.
Methods: Rabbit ADSCs were obtained, cultured, and transfected with Ad-hTGF-beta2 containing human transforming growth factor (hTGF)-beta2. Three days later RT-PCR was used to detect the mRNA expression of hTGF-beta2 in the ADSCs, and ELISA was used to detect the protein expression of hTGF-beta2 in the supernatant.
