OBJECTIVES To characterise the pattern of and risk factors for degenerative changes of the cervical spine in patients with spasmodic torticollis and to assess whether these changes affect outcome after selective peripheral denervation. METHODS Preoperative CT of the upper cervical spine of 34 patients with spasmodic torticollis referred for surgery were reviewed by two radiologists blinded to...

Degenerative changes to the cervical spine can be accompanied by neck pain, which can result from narrowing of the intervertebral disc space and growth of osteophytes. In a lateral x-ray image of the cervical spine, degenerative changes are characterized by vertebral bodies that have indistinct boundaries and limited spacing between vertebrae. In this paper, we present a machine learning approa...

BACKGROUND Ginkgo biloba extract (GbE) is used extensively by breast cancer patients undergoing treatment with Tamoxifen (TAM). Thus, the present study investigated the effects of GbE in female Sprague-Dawley (SD) rats bearing chemically-induced mammary tumors and receiving TAM. METHODS Animals bearing mammary tumors (≥1 cm in diameter) were divided into four groups: TAM [10 mg/kg, intragastr...

background and objective: evaluation of degenerative changes of motoneurons and their related synapses can be useful in understanding the mechanisms of neurodegenerative diseases and their potential treatment. the present electron microscopic and immunohistochemical study investigates the axotomy-induced changes of adult spinal motoneurons up to 3 months following sciatic nerve transection. mat...

The liver has a high regenerative potential that is dependent on many factors, in particular adenosine monophosphate kinase signaling, however, long-term alteration, such as daily alcohol consumption, turns regeneration into chronic disease fibrosis, the end stage of which cirrhosis. Hepatic extracellular matrix proteins are important triggers enhanced stellate cell function during progression ...

BACKGROUND The aim of this study was to assess correlation between pain and degenerative bony changes on cone-beam computed tomography (CBCT) images of temporomandibular joints (TMJs). METHODS Two hundred eighty-three temporomandibular joints with degenerative bony changes were evaluated. Pain intensity (numeric rating scale, NRS) and pain duration in patients with degenerative joint disease ...

Degenerative joint disease (DAD) or osteoarthrosis (OA) is a common among dogs and characterized by being progressive, minimally inflammatory with non-neoplastic neoproliferative alterations, which causes considerable dysfunction in all structures its subsequent failure. Affected animals present lameness, reluctance to move after rest difficulty performing certain activities, these the earliest...

OBJECTIVE The aim of this study was to assess bone changes and mobility in temporomandibular joints (TMJs) using cone beam CT (CBCT) in a population sample in Recife, PE, Brazil. METHODS The TMJ images of patients treated by a radiologist at a private dental radiology service over a period of 1 year were retrieved from the computer database and assessed using a computer with a 21-inch monitor...
