2. 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

3. Immunotherapeutic potential of Crotoxin: anti-inflammatory and immunosuppressive properties
Abstract For the past 80 years, Crotoxin has become one of the most investigated isolated toxins from snake venoms, partially due to its major role as the main toxic component in the venom of the South American rattlesnake Crotalus durissus terrificus. However, in the past decades, progressive studies have led researchers to shift their focus on Crotoxin, op

4. Cytotoxic and pro-apoptotic action of MjTX-I, a phospholipase A2 isolated from Bothrops moojeni snake venom, towards leukemic cells
Abstract Background: Chronic myeloid leukemia (CML) is a BCR-ABL1+ myeloproliferative neoplasm marked by increased myeloproliferation and presence of leukemic cells resistant to apoptosis. The current first-line therapy for CML is administration of the tyrosine kinase inhibitors imatinib mesylate, dasatinib or nilotinib. Although effective to treat CML, som

5. Parenteral adjuvant potential of recombinant B subunit of Escherichia coli heat-labile enterotoxin
BACKGROUND The B subunit of Escherichia coli heat-labile enterotoxin (LTB) is a potent mucosal immune adjuvant. However, there is little information about LTB's potential as a parenteral adjuvant. OBJECTIVES We aimed at evaluating and better understanding rLTB's potential as a parenteral adjuvant using the fused R1 repeat of Mycoplasma hyopneumoniae P97 ad

6. Anticorpos IgE específicos para superantígenos estafilocócicos: grau de sensibilização e associação com a gravidade da asma
RESUMO Objetivo: Determinar a presença de anticorpos IgE específicos para superantígenos estafilocócicos e o grau de sensibilização mediada por esses, assim como se esses estão associados à gravidade da asma em pacientes adultos. Métodos: Estudo transversal incluindo asmáticos adultos em acompanhamento ambulatorial em um hospital universitário t

7. Exposure to 50 Hz electromagnetic field changes the efficiency of the scorpion alpha toxin
AbstractBackground Extremely low-frequency (50 Hz) electromagnetic field (ELF-EMF) is produced by electric power transmission lines and electronic devices of everyday use. Some phenomena are proposed as “first effects” of ELF-EMF: the discrete changes in the membrane potential and the increase of the calcium channel activity as well as the intracellular

8. Desenvolvimento e padronização de testes imunocromatográficos para diagnóstico de Escherichia coli produtora da toxina de Shiga (STEC) e Escherichia coli enterotoxigênica (ETEC). / Development and standardization of immunochromatographic test for Shiga toxin-producing Escherichia coli (STEC) and enterotoxigenic Escherichia coli (ETEC) diagnosis.
Escherichia enterotoxigênica e Escherichia coli produtora da toxina de Shiga (STEC) são globalmente envolvidas em doenças diarreicas e produzem a toxina termolábil e a toxina de Shiga (Stx1 e Stx2), as quais são prejudiciais ao homem. O diagnóstico é uma importante ferramenta para o correto tratamento e controle de surtos. Assim, testes imunocromatogr

9. Clonagem e expressão de um fragmento variável em cadeia única contra a toxina termo-lábil de Escherichia coli enterotoxigênica. / Cloning and expression of a single-chain fragment variable against heat-labile toxin of enterotoxigenic Escherichia coli.
O diagnóstico da infecção por ETEC é baseada na detecção dos seus principais fatores de virulência, as toxinas termo-lábil e termo-estável, através de métodos de biologia molecular ou imunossorológicos. A tecnologia de anticorpos recombinantes permite a obtenção de moléculas com baixo custo, afinidades e especificidades desejáveis, através d

10. Avaliação da atividade antiofídica do composto p-cumarato de triacontila isolado de Bombacopsis glabra e da toxicidade aguda do extrato de Schizolobium parahyba
The use of plant extracts as antidote against animals venoms is an old practice, mainly envenomations by snakes, besides also may used as supplemental of serum therapy. Snake venoms are a rich mixture of proteins involved in a complex series of events that depends on the synergic action of these molecules. The present study explores the ability of Triacontil

11. Enhanced inhibition of murine prostatic carcinoma growth by immunization with or administration of viable human umbilical vein endothelial cells and CRM197
Vaccination with xenogeneic and syngeneic endothelial cells is effective for inhibiting tumor growth. Nontoxic diphtheria toxin (CRM197), as an immunogen or as a specific inhibitor of heparin-binding EGF-like growth factor, has shown promising antitumor activity. Therefore, immunization with or administration of viable human umbilical vein endothelial cells

12. Expression and purification of the immunogenically active fragment B of the Park Williams 8 Corynebacterium diphtheriae strain toxin
The construction of a hexahistidine-tagged version of the B fragment of diphtheria toxin (DTB) represents an important step in the study of the biological properties of DTB because it will permit the production of pure recombinant DTB (rDTB) in less time and with higher yields than currently available. In the present study, the genomic DNA of the Corynebacte
