The diagnostic approach to thyroid cancer is one of the most challenging issues in oncology of the endocrine system because of its high incidence (3.8% of all new cancer cases in the US) and the difficulty to distinguish benign from malignant non-functional thyroid nodules and establish the cervical lymph node involvement during staging. Routine diagnosis of thyroid nodules usually relies on a fine-needle aspirate biopsy, which is invasive and often inaccurate. Therefore, there is an urgent need to identify novel, accurate, and non-invasive diagnostic procedures. Liquid biopsy, as a non-invasive approach for the detection of diagnostic biomarkers for early tumor …

Ilex paraguariensis, Yerba Maté, is a subtropical plant native to South America, where it is consumed several times daily as a tea made with roasted leaves. Several studies have been conducted to elucidate the beneficial effects of this plant. A recent study has shown that saponins isolated from Yerba Maté extract induce apoptosis in human colon cancer cells, while another study indicated that the consumption of Maté tea causes higher incidence of esophageal cancer. Our study looked into the effects Yerba Maté extract have on human breast cancer cells and non-cancer cells from the same tissue. The findings show …

Ilex paraguariensis, also known as Yerba Maté, is a subtropical plant native to South America. In various South American cultures, the leaves of Yerba Maté tree are roasted to make a traditional herbal tea. Several studies have been conducted to elucidate the beneficial effects of this beverage. A recent study has shown that saponins isolated from Yerba Maté extract induce apoptosis in human colon cancer cells, while another study indicated that the consumption of Maté tea causes higher incidence of esophageal cancer. Our study looked into the effects Yerba Maté extract had on human breast cancer cells. The findings …


The Effect Of Maté On Enzymes Involved In The Recovery From Oxidative Stress, Amina Sadik, Theodore Chang Jan 2014

The Effect Of Maté On Enzymes Involved In The Recovery From Oxidative Stress, Amina Sadik, Theodore Chang

College of Osteopathic Medicine (TUN) Publications and Research

In comparing the effect of Maté to that of green tea, it has been shown that Maté has higher anti-oxidative properties. We have shown that the extract of Yerba Maté, paraguariensis, leaves does indeed have strong anti-oxidative properties through the evaluation of its scavenging activity and its ability of assist cardiomyocytes in their recovery from induced oxidative stress using both spectroscopy, a colorimetric assay and flow cytometry. In order to elucidate the mechanism behind this action, we quantified the enzymes known to be expressed naturally by cells under oxidative stress such as glutathione peroxidase, superoxide dismutase, and catalase. These enzymes …
