Abstract Dendritic spines are small protrusions that receive most of the excitatory inputs to the pyramidal neurons in the neocortex and the hippocampus. Excitatory neural circuits in the neocortex and hippocampus are important for experience-dependent changes in brain functions, including postnatal sensory refinement and memory formation. Several lines of evidence indicate that synaptic efficacy is correlated with spine size and structure. Hence, precise and accurate measurement of spine morphology is important for evaluation of neural circuit function and plasticity. Recent advances in light

Study Design: Retrospective case series. Objective: To evaluate if spine measurement software can simulate sagittal alignment following pedicle subtraction osteotomy (PSO). Methods: We retrospectively reviewed consecutive adult spinal deformity patients who underwent lumbar PSO. Sagittal measurements were performed on preoperative lateral, standing radiographs. Sagittal measurements after simulated PSO were compared to actual postoperative measurements. A regression equation was developed using cases 1-7 to determine the amount of manual rotation required of each film to match the simulated sa

Dendritic spines are small protrusions that receive synaptic signals in neuronal networks. The actin cytoskeleton plays a key role in regulating spine morphogenesis, as well as in the function of synapses. Here we report the first quantitative measurement of F-actin retrograde flow rate in dendritic filopodia, the precursor of dendritic spines, and in newly formed spines, using a technique based on photoactivation localization microscopy. We found a fast F-actin retrograde flow in the dendritic filopodia but not in the spine necks. The quantification of F-actin flow rates, combined with fluore

The structure of neuronal dendrites and their spines underlie the connectivity of neural networks. Dendrites, spines, and their dynamics are shaped by genetic programs as well as sensory experience. Dendritic structures and dynamics may therefore be important predictors of the function of neural networks. Based on new imaging approaches and increases in the speed of computation, it has become possible to acquire large sets of high-resolution optical micrographs of neuron structure at length scales small enough to resolve spines. This advance in data acquisition has not been accompanied by comp

Scoliosis is a common spinal condition where the spine curves to the side and thus deforms the spine. Curvature estimation provides a powerful index to evaluate the deformation severity of scoliosis. In current clinical diagnosis, the standard curvature estimation method for assessing the curvature quantitatively is done by measuring the Cobb angle, which is the angle between two lines, drawn perpendicular to the upper endplate of the uppermost vertebra involved and the lower endplate of the lowest vertebra involved. However, manual measurement of spine curvature requires considerable time and

Abstract Background: In the physiotherapeutic practice, the need for measurements of e.g. range of motion or strength of the cervical spine muscles results from a variety of degenerative processes in the area of the head, cervical spine and shoulder girdle. In Poland, we designed a measurement stand based on the equipment described in foreign literature. Validation of the measurement stand was performed in order to determine the usefulness of this stand for measurements of maximal strength and muscle torques for the isometric contraction of the cervical spine muscles.Material/Methods: A group

Accurate measurement of intervertebral kinematics of the cervical spine can support the diagnosis of widespread diseases related to neck pain, such as chronic whiplash dysfunction, arthritis, and segmental degeneration. The natural inaccessibility of the spine, its complex anatomy, and the small range of motion only permit concise measurement in vivo. Low dose X-ray fluoroscopy allows time-continuous screening of cervical spine during patient’s spontaneous motion.

BACKGROUND: Variability that exists amongst the radiographic measurement parameters associated with tibial spine fractures may have direct consequences when comparing, reporting, or treating these injuries. In developing data collection of tibial spine fractures amongst multiple centers, it is important to establish reliability in radiographic parameters. Therefore, we designed a study to validate the classification and a proposed cohort of measurements of tibial spine fractures amongst multiple institutions to assist with standardizing fracture classification and treatment decisions.

Objective To investigate the correlation between bone mineral density (BMD) and duration of injury in individuals with spinal cord injury (SCI).Methods Patients with SCI who visited the outpatient department between January 2009 and January 2019 were enrolled. Patients’ most recent dual energy X-ray absorptiometry images were reviewed. According to the 2007 International Society for Clinical Densitometry guidelines, vertebrae with a local structural change were excluded when deriving spine BMD. If one or no vertebra is suitable for evaluation, spine BMD was judged as “improper for assessment”.

OBJECTIVE Measurement of the occipital condyle–C1 interval (CCI) is important in the evaluation of atlantooccipital dislocation (AOD) in pediatric trauma patients. The authors studied a large cohort of children with and without AOD to identify a 2D measurement threshold that maximizes the diagnostic yield of the CCI on cervical spine CT scans obtained in trauma patients. METHODS This retrospective, single-center study included all children who underwent CT of the cervical spine at Primary Children's Hospital from January 1, 2011, through December 31, 2014, for trauma evaluation. Bilateral CCI

The lumbar spine of 14 cadavers was studied both by 153Gd dual photon absorptiometry (DPA) and quantitative computed tomography (QCT) at 96 and 125 kVp. The intact spine and the individual vertebrae were analyzed. After these measurements the ash content of the vertebral body, the posterior elements, and the transverse processes was determined. The fat content of the vertebral body as well as its volume was also measured. With DPA, the bone mineral content (BMC) determined in situ as well as on excised spine specimens correlated highly with the amount of total vertebral ash (r>0.92, SEE<

Variation in bun morphology was investigated as part of a study to identify the origins of the widespread weed and potential biological control target Tribulus terrestris L. s.1. (Zygophyllaceae). Measurements were made of four size variables, four spine angles and the number of seeds in each bun from 31 Australian and overseas collection sites. Cluster analysis using all variables (valid for 26 collection sites) identified four groups of burrs, one of which contained a single site from Israel that differed due to the angle of the spines. All 31 sites were included by removing the measurement

Background: Treatment decisions for patients with tibial spine fractures heavily rely on radiographic measurements. Therefore, it is important to establish reliability of these parameters to assist with standardizing classification and subsequent treatment decisions. Purpose: To improve upon and subsequently validate a proposed measurement system following a live, in-person case review, re-training, and implementation of a new classification of tibial spine fractures. Methods: Following unacceptable classification reliability amongst the tibial spine research interest group when using the orig
