A comparative performance analysis of total PSA, percentage free PSA, PSA velocity, and PSA density versus the detection of primary circulating prostate cells in predicting initial prostate biopsy findings in chilean men
Reyes, Eduardo [Chile. Universidad Diego Portales]; Orellana,Nelson [Chile. Hospital de Carabineros]; Fuentealba, Cynthia [Chile. Hospital de Carabineros]; Dueñas,Ricardo. [Chile. Hospital de Carabineros] (CIENCIAS, 2014)Introduction. PSA parameters have been used in an attempt to improve the diagnostic yield of prostate screening tests; the detection of primary malignant circulating prostate cells (CPCs) may improve the diagnostic yield ... -
Circulating prostate cells found in men with benign prostate disease are P504S negative: Clinical implications
Murray, Nigel P. [Chile. Universidad Mayor. Facultad de Medicina]; Reyes, Eduardo [Hospital de Carabineros de Chile]; Badinez, Leonardo V. [Chile. Fundación Oncológica Arturo López Pérez]; Orellana, Nelson [Hospital de Carabineros de Chile]; Fuentealba, Chyntia [Hospital de Carabineros de Chile]; Olivares, R. [Hospital de Carabineros de Chile]; Porcell, J. [Hospital de Carabineros de Chile] (Facultad de Ciencias, 2013)Introduction. Developments in immunological and quantitative real-time PCR-based analysis have enabled the detection, enumeration, and characterization of circulating tumor cells (CTCs). It is assumed that the detection ... -
Effect of androgen blockade on her-2 and matrix metalloproteinase-2 expression on bone marrow micrometastasis and stromal cells in men with prostate cancer
Murray, Nigel P. [Chile. Universidad Mayor. Facultad de Medicina]; Reyes, Eduardo [Hospital de Carabineros de Chile]; Badinez, Leonardo V. [Chile. Fundación Oncológica Arturo López Pérez]; Orellana, Nelson [Hospital de Carabineros de Chile]; Fuentealba, Chyntia [Hospital de Carabineros de Chile]; Olivares, R. [Hospital de Carabineros de Chile]; Porcell, J. [Hospital de Carabineros de Chile] (Facultad de Ciencias, 2013)INTRODUCTION: HER-2 has been associated with castrate resistant prostate cancer and matrix metalloproteinase-2 (MMP-2) in the dissemination and invasion of tumor cells as well as activating angiogenesis. We present an ... -
Mitochondria in the Aging Muscles of Flies and Mice: New Perspectives for Old Characters
Jaimovich, Enrique [Universidad de Chile]; Tevy, María Florencia [Chile. Universidad Mayor. Centro de Genómica y Bioinformática] (CIENCIAS, 2016)Sarcopenia is the loss of muscle mass accompanied by a decrease in muscle strength and resistance and is the main cause of disability among the elderly. Muscle loss begins long before there is any clear physical impact in ... -

Instituto de Investigaciones Agropecuarias]; Ginocchio, Rosanna [Chile. Centro de Investigación Minera y Metalúrgica] (Facultad de Ciencias, 2012)The study evaluated the efficacy of organic- and hard-rock mine waste type materials on aided phytostabilization of Cu mine tailings under semiarid Mediterranean conditions in order to promote integrated waste management ... -
Primary circulating prostate cells are not detected in men with low grade small volume prostate cancer
Murray, Nigel P. [Chile. Universidad Mayor. Facultad de Medicina]; Reyes, Eduardo [Hospital de Carabineros de Chile]; Fuentealba, Chyntia [Hospital de Carabineros de Chile]; Orellana, Nelson [Hospital de Carabineros de Chile]; Jacob, Omar [Hospital de Carabineros de Chile] (Facultad de Ciencias, 2014)Objective. To determine if primary circulating prostate cells (CPCs) are found in all men with prostate cancer. Methods and Patients. A prospective study, to analyze all men with an elevated PSA between 4.0 and 10.0 ng/mL ... -
Secondary Circulating Prostate Cells Predict Biochemical Failure in Prostate Cancer Patients after Radical Prostatectomy and without Evidence of Disease
Reyes, Eduardo [Chile.Universidad Diego Portales]; Orellana, Nelson [Chile. Hospital de Carabineros]; Fuentealba, Cynthia [Chile. Hospital de Carabineros] (CIENCIAS, 2013)Introduction. Although 90% of prostate cancer is considered to be localized, 20%-30% of patients will experience biochemical failure (BF), defined as serum PSA >0.2 ng/mL, after radical prostatectomy (RP). The presence of ...
