1. BthTX-I from Bothrops jararacussu induces apoptosis in human breast cancer cell lines and decreases cancer stem cell subpopulation
ABSTRACT Background: Breast cancer is the neoplasm with both the highest incidence and mortality rate among women worldwide. Given the known snake venom cytotoxicity towards several tumor types, we evaluated the effects of BthTX-I from Bothrops jararacussu on MCF7, SKBR3, and MDAMB231 breast cancer cell lines. Methods: BthTX-I cytotoxicity was determined

2. Characterization of Decellularized Human Pericardium for Tissue Engineering and Regenerative Medicine Applications
Resumo Fundameto: O enxerto de pericárdio pode ser usado em muitos procedimentos de correção cirúrgica. Uma das estratégias da engenharia tecidual é o processo de descelularização. No entanto, embora esse processo diminua a resposta imunogênica, a descelularização pode modificar tanto o comportamento como a composição da matriz extracelular nat

3. Cytoarchitecture of the superior olivary complex of three neotropical species of bats (Noctilio leporinus, Phyllostomus hastatus and Carollia perspicillata) with different foraging behavior
Resumo O entendimento da ecolocalização pelo estudo de diferentes núcleos auditivos de morcegos pode ser um elo importante na elucidação das inúmeras questões que surgem em relação ao seu comportamento de forrageamento. O complexo olivar superior (SOC) é o principal centro de processamento das pistas binaurais usadas na localização do som, já qu

4. 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

5. Microscopic alterations in Fasciola hepatica from sheep treated with albendazole
Resumo Na atualidade, o albendazol é uma das drogas mais usadas devido à sua acessibilidade econômica. O objetivo foi avaliar a histopatologia dos espécimes de Fasciola hepatica. Para isso, foi realizado o teste de eficácia em ovinos tratados com albendazol na dose recomendada para Fasciola hepatica, no qual os helmintos recuperados em necropsia foram

6. Immunohistochemical expression of RANKL in oral giant cell lesions is predictive of aggressiveness
Abstract The aim of this study was to evaluate the immunohistochemical expression of receptor activator of nuclear factor kappa-B ligand (RANKL) and of osteoprotegerin (OPG), important proteins correlated with osteoclastogenesis, in central giant cell lesions (CGCL) and peripheral giant cell lesions (PGCL) and to compare their expression with the histologica

7. An in silico pipeline to filter the Toxoplasma gondii proteome for proteins that could traffic to the host cell nucleus and influence host cell epigenetic regulation
Toxoplasma gondii uses epigenetic mechanisms to regulate both endogenous and host cell gene expression. To identify genes with putative epigenetic functions, we developed an in silico pipeline to interrogate the T. gondii proteome of 8313 proteins. Step 1 employs PredictNLS and NucPred to identify genes predicted to target eukaryotic nuclei. Step 2 uses GOLi

8. Lymphoepithelioma-like carcinoma of the skin
Abstract: Primary cutaneous lymphoepithelioma-like carcinoma is a rare disease with low metastatic potential. Its morphologic and pathological features are similar to those of nasopharyngeal lymphoepithelial carcinoma. We report the case of a 60-year-old man with an infrapalpebral pearly papule, measuring 0.6 cm in diameter. The lesion was excised with a cli

9. Long non-coding RNA LINC00261 sensitizes human colon cancer cells to cisplatin therapy
Colon cancer is one of the most common digestive tumors. The present study aimed to explore the functional role, as well as the underlying mechanism of long non-coding RNA LINC00261 in colon cancer. Expression of LINC00261 was analyzed in colon cancer cell lines and human normal cell lines. Acquired resistance cell lines were then built and the acquired resi

10. ‘URS Campestre’ seedless orange: a new mutant with female sterility
ABSTRACT: Seedlessness in fruit is a trait that is much sought after by juice making industries. Close to the city of São Sebastião do Caí, in the state of Rio Grande do Sul (RS), Brazil, a new mutant orange originating from natural mutation was identified and selected as a seedless material. To determine the mechanisms involved in the absence of seeds, t

11. Cytotoxic activity of Androctonus australis hector venom and its toxic fractions on human lung cancer cell line
Abstract Background: Several studies have showed that animal venoms are a source of bioactive compounds that may inhibit the growth of cancer cells, which makes them useful agents for therapeutic applications. Recently, it was established that venom toxins from scorpions induced cytotoxic, antiproliferative and apoptogenic effects on cancer cells. Therefore

12. Autoimmune central diabetes insipidus in a patient with ureaplasma urealyticum infection and review on new triggers of immune response
Diabetes insipidus is a disease in which large volumes of dilute urine (polyuria) are excreted due to vasopressin (AVP) deficiency [central diabetes insipidus (CDI)] or to AVP resistance (nephrogenic diabetes insipidus). In the majority of patients, the occurrence of CDI is related to the destruction or degeneration of neurons of the hypothalamic supraoptic
