1. Prognostic Factors and Management of Colorectal Gastrointestinal Stromal Tumors
Abstract Introduction The gastrointestinal stromal tumor (GIST) is the most common mesenchymal neoplasm of the gastrointestinal tract. Even though it can be found in any location of the digestive tract, the colorectal GIST is rare. With this study, we aim to review the current knowledge regarding the prognosis and management of colorectal GIST. Methods A

2. How does the mitotic index impact patients with T1 melanoma? Comparison between the 7th and 8th edition of the American Joint Committee on Cancer melanoma staging system,
Abstract Background: The mitotic index is no longer used to classify T1 melanoma patients into T1a and T1b, so it should not be used to indicate sentinel node biopsy in these patients. Objectives: To evaluate patients with T1 melanoma who underwent sentinel lymph node biopsy and to compare those who were classified as T1a with those classified T1b, accordi

3. Synthesis of Glycerol-Derived 4-Alkyl-Substituted 1,2,3-Triazoles and Evaluation of Their Fungicidal, Phytotoxic, and Antiproliferative Activities
Herein, the synthesis of nine novel glycerol-derived 4-alkyl-substituted 1,2,3-triazoles, using the CuI-catalyzed alkyne-azide cycloaddition reaction as the key step, is reported. The triazoles were characterized by infrared and nuclear magnetic resonance (NMR 1H and 13C) spectroscopy and mass spectrometry. The nine prepared compounds were evaluated with reg

4. Pretreatment of hepatetctomized rats with Coleus forskohlii did not interfere with the course of hepatic hyperplasia
Abstract Purpose Coleus forskohlii Briq., a medicinal plant originally from India, has been indicated against heart disease, expiratory disorders, convulsions, and hepatic changes, among others. In view of the broad pharmacological potential of the plant and the scarce information about its effects, the objective of the present study was to investigate the

6. Micropropagation and Cellular Behaviour Changes During in vitro Flowering of Impatiens balsamina
RESUMO: Neste estudo, a micropropagação de Impatiens balsamina foi estabelecida a partir de explantes de caule e parte aérea. Os efeitos do GA3 e da glutationa na morfogênese dessa espécie também foram investigados, de modo a induzir o florescimento in vitro. Verificou-se que a melhor regeneração in vitro de plantas foi obtida em meio MS adicionado c

7. Detection of Somaclonal Variation in Micropropagated and Acclimatized Plantlets of Oryza sativa MRQ 74 from Stem Explants
RESUMO: No sistema de cultura de tecidos de plantas, o fornecimento excessivo de hormônios de crescimento vegetal pode inibir o crescimento e desenvolvimento dos regenerantes e, às vezes, induzir a variação somaclonal. Neste estudo, a concentração ideal de hormônios de crescimento para regeneração in vitro de Oryza sativa L. cv. MRQ 74 foi identific

8. Biomonitors to evaluate the toxic potential of urban solid waste landfill leachate
Resumo O aumento acentuado da produção de resíduos sólidos urbanos (RSU) e o consequente acúmulo de lixiviado em aterros potencializam o risco de contaminação do meio ambiente. Biomonitores são utilizados para avaliação da toxicidade dos poluentes sobre os organismos vivos. Neste estudo, foram avaliados o potencial poluidor do lixiviado de RSU de u

9. Aspectos morfológicos do rúmen, omaso e fígado de tourinhos alimentados com diferentes níveis de glicerina bruta
ABSTRACT The morphology of the ruminal and omasal mucosa and hepatic parenchyma of 44 young bulls submitted to four types of concentrates were evaluated by varying the inclusion level of crude Glycerin - CG (0, 6, 12 and 18%). The variables evaluated were number of ruminal papillae per cm² of wall; area of the papillae and total absorption surface per cm²

10. Assesment of the Genotoxic Effect of the Diazinon on Root Cells of Allium cepa (L.)
ABSTRACT Organophosphorous pesticides (OPs) posses a great potential of acute toxicity for exposed animals and men. To evaluate the toxic potential of the organophosphate diazinon on root meristematic cells of Allium cepa L., was created two groups: In group 1 (control group), was not given any chemical. In group 2 (diazinon-treatment group), different doses

11. Analysis of patients diagnosed with primary cutaneous melanoma in the last six years in Hospital Erasto Gaertner: epidemiologic profile
Abstract: BACKGROUND: Melanoma is one of the conditions with greater increase in incidence worldwide in recent decades. It is a skin cancer with potential high lethality and predominates in Caucasian adults. Treatment of primary cutaneous melanoma is essentially surgical and search for sentinel lymph node can modify the aggressiveness of the treatment. OBJ
