Purpose: This study sought to evaluate the biomechanical properties of the interface between the rotator cuff and the semicircular humeral ligament or rotator cable (RCa) using histological and biomechanical techniques.
Methods: Out of 13 eligible cadaver specimens, 5 cadaver shoulders with an intact rotator cuff were included, 8 were excluded due to an injured rotator cuff. The histological study enables us to describe the capsule-tendon interface between the infraspinatus tendon (IST) or supraspinatus tendon (SST) and RCa, and to detect loose connective tissue layers to determine their precise location and measure their length along the interface.
Article Synopsis
- Pelvic gynecological surgeries often lead to complications due to damage to the autonomic nervous system, and recognizing the deep uterine vein (DUV) can help prevent this.
- A systematic literature review and anatomical studies were conducted to better understand the DUV's structure and role in surgical settings, utilizing cadaver dissections and advanced imaging techniques.
- The research confirmed the DUV's importance in dividing uterine regions and assisting surgeons in navigating the subperitoneal anatomy to reduce the risk of nerve and ureter injuries during procedures.
We report a novel hybrid integrated optic device consisting of AlGaInAs/InP electroabsorption modulators and a four-arm silica-on-silicon planar lightwave circuit optical interferometer. The device is designed for generation of high spectral efficiency optical modulation formats. We demonstrate generation of 21.
View Article and Find Full Text PDFA vertical-access passive all-optical gate has been used to improve the extinction ratio of a 160 GHz pico-second pulse train at 1555 nm. An extinction ratio enhancement of 6 dB is observed within an 8 nm bandwidth. Such a device is a promising candidate for low-cost all optical reamplication and reshaping (2R) regeneration at 160 Gbits/s.
