BACKGROUND This study used serial volumetric intravascular ultrasound (IVUS) to evaluate the effect of preinterventional arterial remodeling on in-stent intimal hyperplasia (IH) after implantation of non-polymer-encapsulated paclitaxel-coated stents. METHODS AND RESULTS Patients were randomized to placebo or one of two doses of paclitaxel (low dose, 1.28 microg/mm2; high dose, 3.10 microg/mm2...

the aim of this retrospective statistical study was to determine the prevalcence and frequency of age and sex distributions of pemphigus disease. pemphigus disease classified as autoimmune bullous dermatoses which is a chronic mucocutaneous disease.this study was performed in razi hospital and department of oral pathology of dental school, tehran university of medical sciences. the most frequen...

dermatitis artifacta is a factitious dermatological disorder with many forms of presentation of self inflicted skin lesions in any part of the body. dermatitis artefacta is a difficult condition for diagnosis and treatment mostly because of the patient's denial. the liaison among primary care physicians, psychiatrists and dermatologists can be important in the management of these patients. in t...

BACKGROUND During the extremely challenging 4,487 km ultramarathon TransEurope-FootRace 2009, runners showed considerable reduction of body weight. The effects of this endurance run on brain volume changes but also possible formation of brain edema or new lesions were explored by repeated magnetic resonance imaging (MRI) studies. METHODS A total of 15 runners signed an informed consent to par...

a:1:{i:0;s:867:"Cystic lesions in midline of prostate are uncommon and considered as congenital disorders. Here we report a 33- year- old male who presented with either azoospermia or decreased ejaculate volume leading to infertility and for whom performing Transrectal ultrasonography had a critical role in diagnosis. The obtained images revealed a congenital cyst of the prostate gland just in ...

Sonoelastography is a vibration Doppler technique for imaging the relative elasticity of tissues. Detectability of hard lesions of various sizes has previously been demonstrated in tissue phantoms by our group. Because real tissue differs from phantom material, the injection of formaldehyde in fresh liver tissue is being used as an in-vitro lesion model. Pieces of fresh calf liver were embedded...

PURPOSE To compare the volume of various spaces visible on optical coherence tomography (OCT) images in different angiographic lesion subtypes of neovascular age-related macular degeneration (AMD). METHODS Sixty-six cases of previously untreated, active subfoveal choroidal neovascularization (CNV) associated with AMD were retrospectively collected. CNV lesions were classified as occult with n...

BACKGROUND Lysophosphatidic acid (LPA) is a phospholipid growth factor involved in cell proliferation, differentiation, migration, inflammation, angiogenesis, wound healing, cancer invasion, and survival. This study was directed to evaluate the immunoexpression of LPA-1, cell proliferation, apoptosis, and angiogenesis markers in preneoplastic lesions induced with cadmium chloride in rat prostat...

Diffuse multi-spectral imaging has been evaluated as a potential non-invasive marker of tumor response. Multi-spectral images of Kaposi sarcoma skin lesions were taken over the course of treatment, and blood volume and oxygenation concentration maps were obtained through principal component analysis (PCA) of the data. These images were compared with clinical and pathological responses determine...

BACKGROUND AND PURPOSE Diffusion-weighted imaging (DWI) lesions have been identified both inside and outside the perihematoma region. We tested the hypotheses that larger hematoma volumes and blood pressure reduction are associated with DWI lesions. METHODS Hematoma and perihematoma edema volumes were measured using planimetric techniques in 117 intracerebral hemorrhage (ICH) patients who und...
