In this study, l-131-MIBG imaging was performed in 44 patients with clinical suspicion of tumors originating from neuro-endocrine system. The patients were referred to our department following plasma and urinary measurement of epinephrine, norepinehrine and vanilmandelic acidfVMA). Radionuclide imaging was performel as a comparative or confirmatory measure in all patients who had previous...

The endocrine system refers to the cells and tissue that release hormones into the blood. Unlike synaptic chemical communication, which is localized to the target cell, endocrine communication is global. The hormones act on other endocrine glands such as the adrenal gland, ovaries, testes, and others, as well as on the heart, kidneys, muscle, and the brain. Mathematical modeling has been used t...

Endocrine-disrupting chemicals have the ability to interfere with and alter functions of hormone system, leading adverse effects on reproduction, growth development. Despite growing concerns over their now ubiquitous presence in environment, endocrine-related human health remain largely outside comparative toxicity characterization frameworks as applied for example life cycle impact assessments...

Disorders of the endocrine system including hormone hyperfunction and hypofunction have multiple effects on cardiovascular system. However, in clinical practice, there are many cases of delayed or overlooked diagnosis of underlying endocrine dysfunction in patients presenting chest pain or other cardiac symptoms. Herein, we report three cases of endocrine hyperfunction presenting as coronary sp...

the prognosis of the neoplastic diseases depends not only on the biogenetic characteristics of cancer cells but also on the immunological response of patients, which may influence the biological features of cancer cells themselves as well as the angiogenic processes. moreover, the immune system in vivo is under a physiological psychoneuroendocrine (pne) regulation, mainly mediated by the brain ...

there are increasing evidences that show many xenobiotic chemicals (called as endocrine disruptorchemicals edcs) through interfering with endocrine system, have the capability to induce developmentaland reproductive abnormalities in humans and animals. the yolk protein precursor vitellogenin (vtg) hasproved to be a simple and sensitive biomarker for assessing exposure of fish to edcs especially...

Building on the new synthesis of information introduced at the Wingspread Conference in 1991 (Colborn and Clement, 1992) participants helped frame the concept of “endocrine disruption”. The core observation upon which this concept was based was that some exogenous compounds of both natural and synthetic origin can interact with hormonal systems by one of several mechanisms, including mimicking ...
