Effect of Arrabidaea chica extract against chemically induced breast cancer in animal model

Acta cir. bras; 34 (10), 2019
Abstract Purpose: To examine the effects of Arrabidaa chica (Bignoniacea) extract, a native plant of the Amazon known as crajiru, on a 7,12-dimethyl-1,2-benzanthracene (DMBA)-induced breast cancer model in Wistar rats. Methods: We compared the response of breast cancer to the oral administration of A. ...

Macroglobulinemia de Waldenström: experiencia de 15 años en el Hospital del Salvador, Santiago, Chile

Rev. méd. Chile; 147 (3), 2019
Background: Waldenström macroglobulinemia (WM) is an uncommon indolent B-cell lymphoma, due to the proliferation of lymphoplasmacytic cells, and secretion of a monoclonal IgM protein. Aim: To evaluate the clinical characteristics, management and results of treatment of patients with WM at a public hosp...

Evolución de un linfoma no Hodgkin "triple expresor" en un paciente trasplantado renal con quimioterapia DA-R-EPOCH. Caso clínico

Rev. méd. Chile; 147 (2), 2019
Patients transplanted from solid organs have an increased risk of cancer, especially lymphomas. Lymphomas correspond to 4 to 5% of malignant neoplasms in the general population and in solid organ transplant patients it reaches an incidence of 21%. The incidence of non-Hodgkin lymphomas is 10 times higher...

Sub-chronic administration of vincristine sulfate induces renal damage and apoptosis in rats via induction of oxidative stress and activation of Raf1-MEK1/2-Erk1/2 signal transduction

Int. j. morphol; 37 (1), 2019
SUMMARY: In spite of being one of the most powerful anti-cancer drug, the nephrotoxicity of Vincristine (VCR) is not well established in either animals or humans. Hence, this study evaluates the nephrotoxic effect of VCR in rats after sub-chronic long-term administration. Rats were divided into 2 groups ...

Proteomic changes in a childhood acute lymphoblastic leukemia cell line during the adaptation to vincristine

Abstract: Introduction: Relapse occurs in approximately 20% of Mexican patients with childhood acute lymphoblastic leukemia (ALL). In this group, chemoresistance may be one of the biggest challenges. An overview of complex cellular processes like drug tolerance can be achieved with proteomic studies. ...
