AIM to get a recommendation on the best frailty syndrome diagnostic tools, that will be able to be practiced on a daily setting in Indonesia. METHODS this is a cross-sectional study with diagnostic test approach, conducted to patients in the Geriatric Outpatient Clinic of Cipto Mangunkusumo National Referral Hospital on May-June 2013. Each subject underwent a frailty evaluation using CHS, SOF...

The gaps in the fossil record gave rise to the hypothesis that evolution proceeded in long periods of stasis, which alternated with occasional, rapid changes that yielded evolutionary progress. One mechanism that could cause these punctuated bursts is the recolonization of changing and deserted niches after mass extinction events. Furthermore, paleontological studies have shown that there is a ...

Objective. A. phagocytophilum, an obligate intracellular pathogen, is a well-known agent causing granulocytic infections in both animals and humans. The purpose of the present study was to describe clinical course and consequences of Canine Granulocyctic Anaplasmosis among dogs in Aydin province, Turkey with special reference to hematological alterations and possible interpretations of doxycycl...

CONTEXT The initial diagnosis of pheochromocytoma relies on plasma fractionated metanephrines levels. Normal levels exclude pheochromocytoma, but positive tests have a low positive predictive value due to the disease's rarity. OBJECTIVES The objective of the study was to evaluate three approaches to distinguish between true-positive and false-positive tests: 1) increased cutoff for plasma fra...

Classical Geometry, as conceived by Euclid, was a plataform from which Mathematics started to build its actual form. However, since the XIX century, it was a language that was not evolving as the same pase as the others branches of Physics and Mathematics. In this way, analytic, non-Euclidean and projective geometries, matrix theory, vector calculus, complex numbers, rigid and conformal transfo...

background and objective: neuroendocrine differentiation has not been proved to have effects in behavior of colorectal carcinomas. the aim of this study was immunohistochemical evaluation of neuroendocrine differentiation in colorectal cancer. patients and methods: in this cross-sectional study, 83 paraffin blocks from patients admitted in rasoul-e-akram hospital, tehran, iran, during 2003 to 2...

INTRODUCTION Chromogranin A is a neuroendocrine secretory product and its loss is a feature of malignant NEN de-differentiation. We hypothesized that chromogranin A fragments were differentially expressed during NEN metastasis and played a role in the regulation of NEN proliferation. METHODS Chromogranin A mRNA (PCR) and protein (ELISA/western blot) were studied in 10 normal human mucosa, 5 e...

Chromogranin A is the quantitatively major soluble protein in catecholamine storage vesicles of the adrenal medulla and sympathetic nerve, and has been a useful index of exocytosis during sympathoadrenal neurosecretion. To probe human catecholamine storage and release, we isolated chromogranin A from chromaffin tissue in human pheochromocytoma, and compared it to chromogranin A isolated from ch...

BACKGROUND The neuroendocrine glycoprotein chromogranin A is a useful biomarker in humans for neuroendocrine tumors and stress. Chromogranin A can be measured in both blood and saliva. The objective of this study was to investigate concentrations of and correlation between the chromogranin A epitopes catestatin and vasostatin in healthy dogs accustomed to the sample collection procedures. Blood...

Chromogranins (Cg) are large acidic proteins, co-stored with amines or peptides in the secretory granules of a wide variety of paraneurons. By immunohistochemistry performed on serial semithin sections, the distribution of Cg in the gastroenteropancreatic (GEP) system was analyzed in the endocrine pancreas of 10 mammalian species and in enteroendocrine cells of 6 species. Of the Cg families, Cg...
