Nitinol Spinal Vertebrae: A Favorable New Substitute

Ultrasound Imaging of Spinal Vertebrae to Study Scoliosis

Scoliosis is a musculoskeletal disorder manifested as a three-dimensional spinal deformity. It affects 2% 3% of the adolescent population. The conventional method to diagnose scoliosis is to measure the Cobb angle from posteroanterior radiograph. Since radiation exposure is not desirable for patients, other non-ionizing methods have been explored. Among all the non-ionization methods, ultrasoun...

Cytocompatibility and Genocompatibility Testing of a New Porous Nitinol Alloy

INTRODUCTION: Porous nitinol (PNT) alloys represent new biomaterials for long-term bone implantation. PNT porosity may trigger fluid capillarity, tissue ingrowth, as well as good tissue-implant apposition and fixation. PNT already has many clinical applications including dental and orthopaedic implants. Studies have already confirmed PNT capacity for bone osseointegration and muscle tissue atta...

Mixed Cream Stabilized with Xanthan Gum, a New Substitute for Dairy Cream

Establishment of a new animal model for ischemic lumbar vertebrae.

Degeneration and ischemia of lumbar intervertebral disc has become a more and more important issue for elder people. However the mechanism for this is still known, largely due to a lack of a suitable animal model. In this study, we constructed a new animal model for the study of ischemic lumbar vertebrae. 42 New Zealand white rabbits were chosen for the study. For each rabbit, two vertebrae wer...

Congenital lumbar vertebrae agenesis in a lamb

Congenital agenesis of lumbar vertebrae was diagnosed in a day-old female lamb based on radiology and clinical examinations. There was no neurological deficit in hindlimb and forelimb associated with standing disability. Radiography of the abdominal region revealed absence of lumbar vertebrae. Necropsy confirmed clinical and radiographic results. No other anomaly or agenesis was seen macroscopi...

Two new methods for preparing a unique stratum corneum substitute.

Stratum corneum lipids play an important role in the barrier function of the skin. An in vitro permeation model consisting of synthetic lipids has previously been developed to replace human stratum corneum (SC) in permeation studies. This model is referred to as the stratum corneum substitute (SCS). In order to improve its reproducibility and to increase the efficiency in preparing the SCS, two...
