Recent studies have reported on the molecular mechanisms underlying dendritic spine (spine) dynamics. Because most of these studies investigated spine dynamics by overexpressing constitutively active or dominant-negative PSD (postsynaptic density) proteins in cultured mature neurons, the results represent the enlargement of mature spines or their return to an immature state. Here, we developed ...
The objective of this study was to validate the use of bone mineral measurements of the calcaneus bone by dual X-ray and laser (DXL) in a cross-sectional study carried out in an osteoporosis clinic. Measurements of bone mineral density (BMD) at proximal femur and spine were obtained by dual-energy photon X-ray absorptiometry (DEXA). Osteoporosis was defined by a DEXA T-score <-2.5 at the femora...
Aim: The purpose of this study was to determine the rate of agreement between CT scan interpretations of cervical spine trauma patients between emergency medicines and radiology physicians. Materials and Methods: This cross-sectional analytical study was conducted in Shohadaye Haft-e Tir Hospital, Tehran, Iran. The 408 CT scans for patients with cervical spine trauma registered by the Emergency...
Despite intense attention, the mechanisms regulating dendritic spine structure remain elusive. In this issue of Neuron, Jaworski and colleagues explore the morphological consequences of periodic spine incursions of dynamic microtubules and their associated protein, EB3. Microtubules, long thought to be absent from dendritic spines, are capable of controlling spine morphology, opening up a new l...
To establish an incidence of cervical spine injuries in significant blunt head trauma and to evaluate the necessity of using cervical radiography, all consecutive cases of blunt head trauma admitted to the trauma service over a 7-month period were reviewed. Two hundred twenty-eight charts were reviewed for demographic information, circumstance of injury, complaints and physical findings referab...
PURPOSE Securing the airway of a patient with a potentially unstable cervical spine (C-spine) is a complex and challenging task. The objective of this continuing professional development module is to review the current knowledge essential for airway management in the face of potential C-spine instability and, at the same time, to underline areas of uncertainty and limitations in the literature....
Dendritic spines of rat neostriatal neurons were examined by light microscopy and high voltage stereo electron microscopy (HVEM) following selective staining by intracellular microinjection of horseradish peroxidase. Conventionally prepared material also was used for quantitative analysis of dendritic spines from serial thin sections of neostriatum. Stereo electron microscopy of semithin sectio...
