1. Using the Lugols solution for detection of seconds primary tumors of oral and oropharyngeal in patients with head and neck squamous cell carcinoma: correlation of histopathology findings with immunohistochemical p53 expression and metallothionein. / Uso da solução de Lugol para a detecção de segundos tumores primários de boca e orofaringe em portadores de carcinoma epidermóide na cabeça e pescoço: correlação dos achados na histopatologia com a imunoexpressão do p53 e metalotioneína
The early diagnosis of seconds primary tumors (STP) in patients already treated for carcinoma of the head and neck should be done, because enables a resolutive treatment with low morbidity. The objective of this paper is to evaluate whether chromoscopia using Lugols solution allows an improvement in the identification of malignant or pre malignant lesions in

2. "Contribuição ao estudo da influência da radiação ionizante pré-operatória sobre a marcação do linfonodo sentinela do reto com azul patente: estudo experimental em ratos" / Contribution to the study of the influence of preoperative ionizing radiation on the identification of the sentinel lymph node with patent blue : an experimental study in rats
Previous ionizing radiation induces actinic alterations in peritumoral tissues and thus might influence the localization of the sentinel lymph node. The present study developed an experimental model for the localization of the sentinel lymph node of the rectum of the rat and for the definition of the dose of radiation (calibration curve). The objective was t

3. Loop-Mediated Isothermal Amplification for Detection of African Trypanosomes
While PCR is a method of choice for the detection of African trypanosomes in both humans and animals, the expense of this method negates its use as a diagnostic method for the detection of endemic trypanosomiasis in African countries. The loop-mediated isothermal amplification (LAMP) reaction is a method that amplifies DNA with high specificity, efficiency,

4. Purification of Enterocytozoon bieneusi Spores from Stool Specimens by Gradient and Cell Sorting Techniques
A three-step method for the purification of Enterocytozoon bieneusi spores from stool specimens was developed. The primary process of purification of the spores from bacterial contaminants involved Percoll gradient centrifugation followed by additional separation using cesium chloride density gradient centrifugation. The cesium chloride-isolated spores were
