Magnetic-assisted laparoscopic liver transplantation in swine.
Hepatobiliary Pancreat Dis Int
August 2022
Background: Although laparoscopic technology has achieved rapid development in the surgical field, it has not been applied to liver transplantation, primarily because of difficulties associated with laparoscopic vascular anastomosis. In this study, we introduced a new magnetic-assisted vascular anastomosis technique and explored its application in laparoscopic liver transplantation in pigs.
Methods: Two sets of magnetic vascular anastomosis rings (MVARs) with different diameters were developed.
Article Synopsis
- This study evaluated the effectiveness of incisor movements using clear aligners in a group of 69 non-extraction patients by comparing pretreatment and posttreatment scans.
- The findings indicated that overall, incisor movement efficacy in the sagittal plane was around 55.58%, with pure tipping movements being the most predictable and torque movements the least.
- Results showed that labial root movements were generally more predictable than lingual root movements, suggesting variations in treatment outcomes based on the design of movements and highlighting the need for improved understanding of clear aligner biomechanics.
Co-culture of bone marrow stromal cells (BMSCs) and vascular endothelial cells (VECs) is a promising strategy for better osteogenesis and pre-vascularization in bone tissue engineering. Recent reports have shown that mechanical stretching further promotes osteogenesis in BMSC/VEC co-culture systems, but the underlying mechanism of this process remains unclear. In this study, noncontact co-cultures of rat primary BMSCs and VECs were employed to interrogate paracrine cell-to-cell communications in response to tension.

Purpose: To analyze the clinical effect of extraction correction of patients with maxillary protrusion by using Damon high torque appliances.
Methods: Forty patients with extraction of four first premolars due to orthodontic treatment were selected. They had protrusion of maxilla and were randomly divided into two groups.
