    Nutrigenomics and nutrigenetics

    The nutrients are able to interact with molecular mechanisms and modulate the physiological functions in the body. The Nutritional Genomics focuses on the interaction between bioactive food components and the genome, which includes Nutrigenetics and Nutrigenomics. The influence of nutrients on f genes expression is called Nutrigenomics, while the heterogeneous response of gene variants to nutrients, dietary components and developing nutraceticals is called Nutrigenetics. Genetic variation is known to affect food tolerances among human subpopulations and may also influence dietary requirements and raising the possibility of individualizing nutritional intake for optimal health and disease prevention on the basis of an individual's genome. Nutrigenomics provides a genetic understanding for how common dietary components affect the balance between health and disease by altering the expression and/or structure of an individual's genetic makeup. Nutrigenetics describes that the genetic profile have impact on the response of body to bioactive food components by influencing their absorption, metabolism, and site of action. In this way, considering different aspects of gene-nutrient interaction and designing appropriate diet for every specific genotype that optimize individual health, diagnosis and nutritional treatment of genome instability, we could prevent and control conversion of healthy phenotype to diseases

    A novel succinate dehydrogenase type B mutation in an Iranian family. Its genetic and clinical evaluation

    Succinate Dehydrogenase-B (SDH-B) gene mutations constitute one of the most frequent forms of hereditary paragangliomas (PGL). Genetic study is advised in all cases for the evaluation of tumour behaviour, the selection of optimal management and the surveillance of the first degree relatives. There are limited data on the genetic characteristics of patients with PGLs from Middle East countries, and to our knowledge this is the first study from Iran. We present the clinical and genetic characteristics of a 29-year old woman who presented with hypertension secondary to a para-aortic PGL. She was shown to have a novel mutation in the SDH-B gene and her family was subsequently screened. We also emphasize the problems in diagnosing and treating patients in this region. © 2014 Hellenic Endocrine Society. All rights reserved

    Antiphospholipid antibody syndrome presenting with pulmonary embolism

    Antiphospholipid antibody syndrome (APS) is a recently-diagnosed syndrome presenting with arterial and venous thrombosis, recurrent miscarriages and thrombocytopenia in the presence of antiphospholipid antibodies. A 16- year-old man referred due to right sided chest pain, dyspnea and cyanosis of two fingers presented for 2 months. After a complete workup, diagnosis of pulmonary thromboembolism was confirmed through clinical examination, spiral chest CT-scan and lower limb Doppler sonography. He had positive anticardiolipin antibody, lupus anticoagulant, ANA and anti dsDNA. Based on these findings, diagnosis of APS (probably secondary to SLE) was made. Symptoms were improved by anticoagulant, prednisolone and chloroquine therapy. In a conclusion, pulmonary embolism may be the first presentation of APS, especially in young adults. © 2008 NRITLD, National Research Institute of Tuberculosis and Lung Disease, Iran
