Benign and malignant nodules in human thyroid glands, which did not concentrate iodide in vivo, were also unable to accumulate iodide in vitro. The mean thyroid-to-medium ratio (T/M) in seven benign nodules was 0.8+/-0.2 compared with 7+/-2 in adjacent normal thyroid tissue. In four malignant thyroid nodules, the mean T/M was 0.5+/-0.1 compared with 11+/-4 in adjacent normal thyroid. Despite th...

results out of the 129 elderly participants, aged between 60-87 years (mean: 66.71 ± 6.21), males constituted 58.1% (n = 75) of patients and female were 41.9% (n = 54). normal variations of oral mucosa were observed in 62% (n = 80) of patients, while 44.2% (n = 57) had oral mucosal lesions. normal variations were significantly associated with smoking (or = 1.2), while denture wearers were at hi...

Pathological changes in the connective tissue of the limbs of MRL/1 mice are described. Focal infiltrates of polymorphs or large mononuclear cells, or both, were seen both in synovial lining and subcutaneous tissue. Infiltrates were associated with vasculitis in some cases. Deposits of amorphous material were seen in and around joints and in foot pads. The material was more particulate and refr...

We have previously shown that high-frequency, high-resolution ultrasound can characterize the acoustic properties and composition of fatty plaques in cholesterol-fed rabbits. To determine whether quantitative ultrasound can delineate the regression of atherosclerotic lesions by detecting a change in their composition from fatty to fibrous types induced by alterations in dietary regimen, we fed ...

Fibrous dysplasia (FD) belongs to a group of lesions known as fibro osseous lesions (FOL) whereby normal bone is replaced with fibrous tissue containing abnormal bone or cementum. FOL are the most frequent and the most difficult lesions to diagnose, as they share overlapping spectrum of clinicopathological, radiological, and immunological characteristics. In this retrospective study of 134 maxi...

BACKGROUND AND PURPOSE DTI is an MR imaging measure of brain tissue integrity and provides an attractive metric for use in neuroprotection clinical trials. The purpose of our study was to use DTI to evaluate the longitudinal changes in brain tissue integrity in a group of patients with MS. MATERIALS AND METHODS Twenty-one patients with MS starting natalizumab were imaged serially for 12 month...

We have previously developed a conductive hydrogel for use as an intermediate between heart tissue and catheter tips in cardiac ablation, providing more uniform precisely shaped lesion with the goal of minimizing occurrence steam pops repeat procedures arrythmia patients. Characterization gel has involved repeated porcine hearts approximation ablation behavior human models. As this will require...

Background Endometriosis is a gynecological disease defined as the presence of endometrial tissue outside the uterine cavity, which caused by various factors. Recent evidences support the presence of endometrial stem cells and their possible involvement in endometriosis. Related studies mainly focus on stemness-related genes, and pluripotency markers may play a role in the etiology of endometri...
