Nobiletin and xanthohumol counteract the TNFα-mediated activation of endothelial cells through the inhibition of the NF-κB signaling pathway.

2022

Angiogenesis, a process characterized by the formation of new blood vessels from pre-existing ones, is a crucial step in tumor growth and dissemination. Given the ability of tumors to interfere with multiple or different molecular pathways to promote angiogenesis, there is an increasing need to therapeutically block tumor progression by targeting multiple antiangiogenic pathways. Natural polyphenols present health-protective properties, which are likely attributed to their ability to activate multiple pathways involved in inflammation, carcinogenesis, and angiogenesis. Recently, increased attention has been addressed to the ability of flavonoids, the most abundant polyphenols in the diet, t…

Antitumor Cell-Complex Vaccines Employing Genetically Modified Tumor Cells and Fibroblasts

2014

The present study evaluates the immune response mediated by vaccination with cell complexes composed of irradiated B16 tumor cells and mouse fibroblasts genetically modified to produce GM-CSF. The animals were vaccinated with free B16 cells or cell complexes. We employed two gene plasmid constructions: one high producer (pMok) and a low producer (p2F). Tumor transplant was performed by injection of B16 tumor cells. Plasma levels of total IgG and its subtypes were measured by ELISA. Tumor volumes were measured and survival curves were obtained. The study resulted in a cell complex vaccine able to stimulate the immune system to produce specific anti-tumor membrane proteins (TMP) IgG. In the g…

Pancreatic ductal adenocarcinoma (PDAC) is one of the main aggressive types of cancer, characterized by late prognosis and drug resistance. Among the main factors sustaining PDAC progression, the alteration of cell metabolism has emerged to have a key role in PDAC cell proliferation, invasion, and resistance to standard chemotherapeutic agents. Taking into account all these factors and the urgency in evaluating novel options to treat PDAC, in the present work we reported the synthesis of a new series of indolyl-7-azaindolyl triazine compounds inspired by marine bis-indolyl alkaloids. We first assessed the ability of the new triazine compounds to inhibit the enzymatic activity of pyruvate de…

Odontoma intraóseo erupcionado: Una infrecuente patología

2005

Objetivos: Los odontomas que afectan a los tejidos blandos son muy infrecuentes, pudiendo presentarse bajo dos formas clinicas: odontoma periférico y odontoma erupcionado. Se documenta un caso de odontoma erupcionado con el objetivo de discutir entre ambas formas de presentación clínica de esta patología. Diseño del estudio: Estudio de caso. Resultados: Se presenta el caso de un varón con una masa dura localizada en la región posterior del reborde alveolar izquierdo del maxilar superior, de un año de evolución y lento crecimiento. La ortopantomografía mostró la presencia de una tumoración radiodensa en la región posterior del maxilar izquierdo. El estudio histológico de la pieza operatoria …

Adherence to oral hormonal anticancer agents in breast cancer.

2022

There is an increasing trend towards using oral antitumoral agents in oncological patients. Compared to parenteral therapy, oral treatment offers convenience for both the patient and the healthcare system, with similar efficacy. However, the benefit deriving from oral drugs will be obtained only if patients adhere strictly to the treatment. Medical oncologists must therefore seek to optimize patient adherence. Breast cancer patients, particularly, are often treated with oral hormonal anticancer agents. In this review, we summarized evidence about adherence of breast cancer patients to oral hormonal anticancer agents and the consequences of poor compliance, the barriers to oral treatment an…

Clinical characteristics of oral chronic graft-versus-host disease according to the 2014 National Institutes of Health (USA) consensus criteria.

2022

Chronic graft-versus-host disease (cGVHD) is a serious and common complication of allogeneic hematopoietic cell transplantation (alloHCT). The oral cavity is the second most common site affected by cGVHD. In 2014, the 2005 National Institutes of Health (NIH) consensus criteria were revised to address areas of controversy. The aim of this study was to evaluate the clinical characteristics of oral cGVHD using the 2014 NIH consensus criteria. The baseline data of oral manifestation of patients, who were diagnosed with oral cGVHD, in the first dental visit were analyzed (n=22). The oral mucosal disease was evaluated by NIH modified Oral Mucosa Rating Scale (OMRS) and Thongprasom sign score. The…
