A Localisation-Segmentation Approach for Multi-label Annotation of Lumbar Vertebrae using Deep Nets [PDF]
arXiv, 2017 Multi-class segmentation of vertebrae is a non-trivial task mainly due to the high correlation in the appearance of adjacent vertebrae. Hence, such a task calls for the consideration of both global and local context. Based on this motivation, we propose a two-staged approach that, given a computed tomography dataset of the spine, segments the five ...

Survivorship of Individuals With Double Heterozygosity for Achondroplasia and Type 2 Collagenopathy
American Journal of Medical Genetics Part A, EarlyView.ABSTRACT Historically, double heterozygosity, or a diagnosis of two separate, dominant genetic conditions, was often thought to be lethal in individuals with autosomal dominant skeletal dysplasias. In previously published studies of individuals with dual dysplasia diagnoses of achondroplasia and type 2 collagenopathy, infants died of respiratory ...

The Anatomical Record, EarlyView.Abstract Plutonium was discovered and first synthesized in the early 1940's. Several isotopes of plutonium are used in nuclear technologies, 238Pu for heat generation and 239Pu for energy production and weapons. Both isotopes emit alpha particles, which pose a significant radiation hazard when incorporated into the body.

Analysis of Nkx3.1:Cre-driven Erk5 deletion reveals a profound spinal deformity which is linked to increased osteoclast activity [PDF]
, 2017 Extracellular signal-regulated protein kinase 5 (ERK5) has been implicated during development and carcinogenesis. Nkx3.1-mediated Cre expression is a useful strategy to genetically manipulate the mouse prostate. While grossly normal at birth, we observed

Acta Veterinaria, 2023 Numerous studies are based on the use of animal models; however, in bipedal and tetrapedal organisms there are significant differences in the biomechanics of the spinal column, which can significantly impair the quality and applicability of the results ...

The Ladder Algorithm: Finding Repetitive Structures in Medical Images by Induction [PDF]
arXiv, 2020 In this paper we introduce the Ladder Algorithm; a novel recurrent algorithm to detect repetitive structures in natural images with high accuracy using little training data. We then demonstrate the algorithm on the task of extracting vertebrae from whole spine magnetic resonance scans with only lumbar MR scans for training data.

Expert Perspective: How, When, and Why to Potentially Stop Antiresorptive Drugs in Osteoporosis
Arthritis &Rheumatology, EarlyView.Osteoporosis is a chronic disease, and antiresorptive treatments are often continued for many years. Despite their established efficacy in reducing fracture risk, the most commonly used antiresorptive treatments, bisphosphonates and denosumab, have short‐ and long‐term risks that, coupled with their benefits and other unique characteristics, influence ...

Reverse engineering applied to a lumbar vertebra [PDF]
, 2007 Bone studies can be made in vivo or in vitro. However, disadvantages of both traditional techniques call for a compromise between the two. Reverse engineering allows in vitro bone samples to be simulated and analysed in a virtual in vivo environment thus
