vulvar cancer is a rare gynecological malignancy with mainly lymphatic spread. sentinel node mapping plays an important role in the management of this gynecological malignancy. in the current study, we reported our experience in sentinel node mapping of vulvar cancer and review the literature accordingly. since the introduction of sentinel node mapping to the surgical oncology community of our ...

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 ...

Yeast hexokinase, a homodimer (100 kDa), is an important enzyme in the glycolytic pathway. Although Cibacron Blue 3G-A (Reactive Blue 2) has been previously shown to inactivate yeast hexokinase, no comprehensive study exists concerning the nature of interaction(s) between hexokinase and the blue dye. A comparison of the computer-generated three-dimensional (3D) representations showed considerab...

When uninjured cells of Valonia are placed in methylene blue dissolved in sea water it is found, after 1 to 3 hours, that at pH 5.5 practically no dye penetrates, while at pH 9.5 more enters the vacuole. As the cells become injured more dye enters at pH 5.5, as well as at pH 9.5. No dye in reduced form is found in the sap of uninjured cells exposed from 1 to 3 hours to methylene blue in sea wat...

In this study, montmorillonite clay was used as the adsorbent for the removal of Aniline Blue dye, from aqueous solution by the batch adsorption technique under different conditions. The maximum removal of aniline blue dye for initial dye concentration 20 mg/L was more than 95% at optimum conditions (pH=4.5, contact time=30 min, and adsorbent dosage=2 g/L). The data of this study were fitted wi...

the optimization of process conditions for the degradation of acid blue 193 by uv/peroxydisulfate was investigated using response surface methodology (rsm). the effects of four parameters namely initial k2s2o8 concentration, uv irradiation, temperature, and initial dye concentration on two process responses, color removal and the rate constants of the first-order kinetic equations, were investi...

introduction: in the current study we evaluated the incremental value of lateral pelvic lymphoscintigraphy imaging of endometrial or cervical cancer patients who underwent sentinel node mapping. methods: operable endometrial and cervical cancer patients without clinical or paraclinical evidence of lymph node involvement were included in the study. the day before surgery the patients were sent ...
