abstract background and aims. reliable immunohistochemical assays to evaluate the definitive role of mast cells and angiogenesis in the pathogenesis of oral reactive lesions are generally not available. the purpose of the present study was to compare mast cell count (mcc) and microvessel density (mvd) between oral reactive lesions and evaluation of the correlation between mcc and mvd in these l...

background: psoriasis is a common chronic and relapsing skin disease with unknown etiology being observed at any age and any gender, having a 1. 5-3% prevalence rate among the general population. psoriatic lesions consist of pruritic and scaling papules, residing on an erythematous base, which are more commonly found on the scalp, extensor surfaces, palms and soles, and the nails. the conventio...

coronary artery disease is the leading cause of death worldwide. in this study, we compared two surgical methods of left internal mammary artery (lima) anastomosis on left anterior descending (lad) artery in patients with severe diffuse lesions. a total of 40 patients were included in our study and randomly assigned into two groups. in group a, after a long arteriotomy on lad, the posterior sur...

this paper introduces a novel methodology for the segmentation of brain ms lesions in mri volumes using a new clustering algorithm named scpfcm.  scpfcm uses membership, typicality and spatial information to cluster each voxel. the proposed method relies on an initial segmentation of ms lesions in t1-w and t2-w images by applying scpfcm algorithm, and the t1 image is then used as a mask and is ...

BACKGROUND Cervical cancer is the third most common cancer in Brazil and has a high potential for prevention and cure. The prevalence of invasive and preinvasive disease in women with cytological diagnosis of high-grade lesion - cannot exclude microinvasion (HSIL-micro) is not known. METHODS This cross-sectional study used a cytology lab database to identify women with HSIL-micro and HSIL ref...

background: cutaneous leishmaniasis is an annoying and disfiguring disease affecting around 1,500,000 individuals globally. there are endemic pockets of this disease in taif region. in some patients, lesion often weeps and leads to scar formation. the study was conducted to see the efficacy of fluconazole and itraconazole in the patients of cutaneous leishmaniasis and the effect of these drugs ...

breast cancer is a major public health problem for women in the iran and many other parts of the world. dynamic contrast-enhanced magnetic resonance imaging (dce-mri) plays a pivotal role in breast cancer care, including detection, diagnosis, and treatment monitoring. but segmentation of these images which is seriously affected by intensity inhomogeneities created by radio-frequency coils, is a...

breast lesion segmentation in mr images is one of the most important parts of clinical diagnostic tools. pixel classification methods have been frequently used in image segmentation with two supervised and unsupervised approaches up to now. supervised segmentation methods lead to high accuracy, but they need a large amount of labeled data, which is hard, expensive, and slow to be obtained. on t...

Fenestrated vertebrobasilar junction aneurysms are rare vascular lesions. Microsurgical intervention is extremely difficult due to the complex anatomy in the vicinity of these aneurysms. Endovascular neurosurgery appears to be safe and should be considered as the first modality of treatment. This case study details the treatment of an unruptured fusiform fenestrated vertebrobasilar junction ane...
