BACKGROUND AND OBJECTIVE With advances in mammographic equipment and techniques, more and more nonpalpable breast lesions have been detected. This study was to investigate the application of methylene blue dye for localized biopsy to diagnose nonpalpable breast lesions. METHODS In total 138 patients with suspicious malignant, nonpalpable breast lesions between August 2002 and October 2006 wer...

in medicine, patent blue violet (pbv) is utilized for staining lymphatic vessels in sentinel lymph node (sln) surgery. moreover, pbv (also called e131 ) is used as food additive. we report on a 51-year-old non-atopic female with early breast cancer, who was scheduled for sln excision and experienced an intra-operative anaphylactic reaction. in diagnostics the skin prick test (spt) was positive ...

introduction: development of brain edema following focal cerebral ischemia exacerbates primary ischemic injury. blood brain barrier (bbb) opening is an important part of edema named as vasogenic brain edema. in this study, quantitative alterations of bbb permeability is experimentally evaluated using transient focal cerebral ischemia in the rat. methods: two groups of male rats (ischemic and sh...

statement of problem: early diagnoses of oral malignancies and pre-malignancies have direct effect in the outcome of these lesions. therefore the techniques for early diagnosis have been considered as useful method in practice. purpose: the aim of this study was to evaluate the reliability of oratest and generic toluidine blue (gtb) in the detection of oral malignancy and premalignancy. materia...

Toxic heavy-metal pollution represents one of the most pressing environmental challenges that humankind faces today. The conventional approaches for removing highly toxic and carcinogenic heavy metals are currently unsuitable practical applications. reduction harmful metals, such as hexavalent chromium (Cr(VI)) into less trivalent Cr(III), has been gaining considerable interest. In response to ...

In the current survey, the removal of dye from contaminated water was studied by photocatalytic degradation using TiO2 nanoparticles with respect to pH, TiO2 dosage, reaction time, temperature and initial dye concentration. TiO2 nanoparticles were investigated by XRD, FESEM and FT-IR.The RSM was chosen to study the composition effects of input independent factor...

blue nevi are uncommon, asymptomatic lesions of the uterine cervix. these lesions are not often detected clinically or on colposcopy. careful histopathological examination is required. the nevus cells are said to originate from the immature melanoblasts of the neural crest. these lesions need to be differentiated from malignant melanoma and melanosis of the cervix. we present here a case report...
