BACKGROUND To investigate the value of diffusion-weighted imaging (DWI) at 3.0 T (3T), and especially the apparent diffusion coefficient (ADC), in discriminating ovarian thecoma from other adnexal solid masses. METHODS Eighteen thecomas or fibrothecomas, 14 ligamentous leiomyomas, and 24 other ovarian solid tumors underwent prospective DWI magnetic resonance imaging (MRI) in addition to routi...

OBJECTIVES To evaluate immunohistochemically various parameters of inflammation in coronary atherectomy specimens obtained from restenotic culprit lesions of patients presenting with either stable or unstable angina (UA). BACKGROUND There is no information regarding the relationship between atherosclerotic plaque inflammation and the severity of the coronary syndromes in patients with resteno...

To quantify the effects of methylmercury (MeHg) on amacrine and on ON-bipolar cells in the retina, experiments were performed in MeHgexposed groups of adult trahiras (Hoplias malabaricus) at two dose levels (2 and 6 μg/g, ip). The retinas of test and control groups were processed by mouse anti-parvalbumin and rabbit anti-αprotein kinase C (αPKC) immunocytochemistry. Morphology and soma location...

BACKGROUND/AIM Primary therapeutic approach to lumbar ureteral stones is still contraversial. The aim of the study was to investigate the influence of stone impaction and size on the effectiveness of proximal ureteral stone lithotripsy. METHODS A total of 123 patients with proximal ureteral stones were investigated in this prospective study performed in a 10-month period. The patients were di...

The quantification of angiogenic and linfangiogenic factors has been explored in an attempt to predict the prognosis of various malignancies. In gastric cancer (GC), a promising parameter is the microvessel density (MVD). Objective: The aim of our study is to evaluate the different methods used for its quantification. Methods: 52 cases of GC were labeled by immunohistochemistry for CD34, CD105 ...

OBJECTIVE To evaluate the feasibility of a parameter-free intravoxel incoherent motion (IVIM) approach in cervical cancer, to assess the optimal b-value threshold, and to preliminarily examine differences in the derived perfusion and diffusion parameters for different histological cancer types. MATERIALS AND METHODS After Institutional Review Board approval, 19 female patients (mean age, 54 y...

PURPOSE We tested the hypothesis that experimental glaucoma (EG) results in greater thinning of the optic nerve head (ONH) neural rim tissue than the peripapillary retinal nerve fiber layer (RNFL) tissue. METHODS Longitudinal spectral-domain optical coherence tomography (SDOCT) imaging of the ONH and peripapillary RNFL was performed every other week under manometric IOP control (10 mm Hg) in ...

OBJECTIVE To determine the effects of a minimally invasive transilial vertebral (MTV) blocking procedure on the computed tomographic (CT) appearance of the lumbosacral (L7/S1) junction of dogs with degenerative lumbosacral stenosis (DLSS). STUDY DESIGN Prospective study. ANIMALS 59 client-owned dogs with DLSS. METHODS Lumbosacral CT images were acquired with hyperextended pelvic limbs bef...

Objectives To investigate the effects of region of interest (ROI) sizes on apparent diffusion coefficient (ADC) measurements for the differentiation of normal pancreas (NP), pancreatic ductal adenocarcinoma (PDAC) and mass-forming chronic pancreatitis (MFCP). Results There were no significant differences for the mean ADCs measured by 12 different-size ROIs for MFCP, or PDAC and NP (P = 0.858-...

breast cancer is common and is considered second cause of cancer related mortality in females. regarding importance of breast cancer, more investigation in this field is recommended. for many years investigators believed that neoplasms were not innervated but new findings have proved otherwise. this descriptive study was carried out to compare number of nerve fibers in benign, malignant and nor...
