Androgen Excess in Breast Cancer Development: Implications for Prevention and Treatment
26 2 Endocrine-Related G Secreto et al. Androgen excess in breast 26:2 R81–R94 Cancer cancer development REVIEW Androgen excess in breast cancer development: implications for prevention and treatment Giorgio Secreto1, Alessandro Girombelli2 and Vittorio Krogh1 1Epidemiology and Prevention Unit, Fondazione IRCCS – Istituto Nazionale dei Tumori, Milano, Italy 2Anesthesia and Critical Care Medicine, ASST – Grande Ospedale Metropolitano Niguarda, Milano, Italy Correspondence should be addressed to G Secreto: [email protected] Abstract The aim of this review is to highlight the pivotal role of androgen excess in the Key Words development of breast cancer. Available evidence suggests that testosterone f breast cancer controls breast epithelial growth through a balanced interaction between its two f ER-positive active metabolites: cell proliferation is promoted by estradiol while it is inhibited by f ER-negative dihydrotestosterone. A chronic overproduction of testosterone (e.g. ovarian stromal f androgen/estrogen balance hyperplasia) results in an increased estrogen production and cell proliferation that f androgen excess are no longer counterbalanced by dihydrotestosterone. This shift in the androgen/ f testosterone estrogen balance partakes in the genesis of ER-positive tumors. The mammary gland f estradiol is a modified apocrine gland, a fact rarely considered in breast carcinogenesis. When f dihydrotestosterone stimulated by androgens, apocrine cells synthesize epidermal growth factor (EGF) that triggers the ErbB family receptors. These include the EGF receptor and the human epithelial growth factor 2, both well known for stimulating cellular proliferation. As a result, an excessive production of androgens is capable of directly stimulating growth in apocrine and apocrine-like tumors, a subset of ER-negative/AR-positive tumors. -
The Creation of Neuroscience
The Creation of Neuroscience The Society for Neuroscience and the Quest for Disciplinary Unity 1969-1995 Introduction rom the molecular biology of a single neuron to the breathtakingly complex circuitry of the entire human nervous system, our understanding of the brain and how it works has undergone radical F changes over the past century. These advances have brought us tantalizingly closer to genu- inely mechanistic and scientifically rigorous explanations of how the brain’s roughly 100 billion neurons, interacting through trillions of synaptic connections, function both as single units and as larger ensem- bles. The professional field of neuroscience, in keeping pace with these important scientific develop- ments, has dramatically reshaped the organization of biological sciences across the globe over the last 50 years. Much like physics during its dominant era in the 1950s and 1960s, neuroscience has become the leading scientific discipline with regard to funding, numbers of scientists, and numbers of trainees. Furthermore, neuroscience as fact, explanation, and myth has just as dramatically redrawn our cultural landscape and redefined how Western popular culture understands who we are as individuals. In the 1950s, especially in the United States, Freud and his successors stood at the center of all cultural expla- nations for psychological suffering. In the new millennium, we perceive such suffering as erupting no longer from a repressed unconscious but, instead, from a pathophysiology rooted in and caused by brain abnormalities and dysfunctions. Indeed, the normal as well as the pathological have become thoroughly neurobiological in the last several decades. In the process, entirely new vistas have opened up in fields ranging from neuroeconomics and neurophilosophy to consumer products, as exemplified by an entire line of soft drinks advertised as offering “neuro” benefits. -

Born in Wales in 1912, Richard Llewelyn-Davies was educated at Trinity College, Cambridge, !'Ecole des Beaux Arts in Paris and the Architectural Association in London. In 1960 he began a fif teen-year association with University College of the University of London as Professor of Architecture, Professor of Town Planning, Head of the Bartlett School of Architecture and Dean of the School of Environmental Studies. He became, in 1967, the initial chair man of Britain's Centre for Environmental Studies, one of the world's leading research organizations on urbanism, and held that post for the rest of his life. He combined his academic career with professional practice in England, the Middle East, Africa, Paki stan, North and South America. In the fall of 1980, the year before he died, Richard Llewelyn Davies came to the Institute for Advanced Study. He influenced us in many ways, from a reorientation of the seating arrangement in the seminar room improving discussion and exchange, to the per manent implantation of an environmental sensibility. -

Estrogen Deficiency During Menopause and Its Management: a Current Update V
Review Article Estrogen deficiency during menopause and its management: A current update V. T. Hemalatha1, A. Julius2, S. P. Kishore Kumar3, L. Vijayalakshmi4, Shankar Narayanan1 ABSTRACT Different phases of a woman’s life: Puberty, menses, pregnancy, and menopause have varied influence on her oral health. During the menopause, women go through biological and endocrine changes, particularly in their sex steroid hormone production, affecting their health. Sex hormones strongly influence body fat distribution and adipocyte differentiation. Estrogens and testosterone differentially affect adipocyte physiology, but the importance of estrogens in the development of metabolic diseases during menopause is disputed. Estrogens and estrogens receptor regulate various aspects of glucose and lipid metabolism. Disturbances of this metabolic signal lead to the development of metabolic syndrome and a higher cardiovascular risk in woman. The absence of estrogens is a clue factor in the onset of cardiovascular disease during the menopausal period, which is characterized by lipid profile variations and predominant abdominal fat accumulation. However, influence of the absence of these hormones and its relationship to higher obesity in women during menopause is not clear. This systematic review discusses of the role of estrogens and estrogen receptors in adipocyte differentiation and its various effects and brief discussion on its management. KEY WORDS: Estrogen hormone (estrogens/progestogens) replacement therapy, Menopause, Weight gain INTRODUCTION BODY CHANGES AT MENOPAUSE Menopause occurs when a woman stops ovulating and As we age, our muscles decrease in bulk and our her monthly period (menstruation) stops. metabolism slows down. These changes cancontribute to weight gain around the time of menopause. Other As women age, into their 40s and 50s, there is a tendency physical changes associated with menopause may to gain weight. -

Preprint (not copyedited or formatted) Please use DOI when citing or quoting: https://doi- org.proxy.wexler.hunter.cuny.edu/10.1017/S0269889714000313 The Birth of Information in the Brain: Edgar Adrian and the Vacuum Tube Word Count: 10, 418 Abstract: As historian Henning Schmidgen notes, the scientific study of the nervous system would have been ‘unthinkable’ without the industrialization of communication in the 1830s. Historians have investigated extensively the way nerve physiologists have borrowed concepts and tools from the field of communications, particularly regarding the nineteenth-century work of figures like Helmholtz and in the American Cold War Era. The following focuses specifically on the interwar research of the Cambridge physiologist Edgar Douglas Adrian, and on the technology that led to his Nobel-Prize- winning research, the thermionic vacuum tube. Many countries used the vacuum tube during the war for the purpose of amplifying and intercepting coded messages. These events provided a context for Adrian’s evolving understanding of the nerve fiber in the 1920s. In particular, they provide the background for Adrian’s transition around 1926 to describing the nerve impulse in terms of “information,” “messages,” “signals,” or even “codes,” and for translating the basic principles of the nerve, such as the all-or-none principle and adaptation, into such an “informational” context. The following also places Adrian’s research in the broader context of the changing relationship between science and technology, and between physics and physiology, in the first few decades of the twentieth century. -

Management of Women with Premature Ovarian Insufficiency
Management of women with premature ovarian insufficiency Guideline of the European Society of Human Reproduction and Embryology POI Guideline Development Group December 2015 1 Disclaimer The European Society of Human Reproduction and Embryology (hereinafter referred to as 'ESHRE') developed the current clinical practice guideline, to provide clinical recommendations to improve the quality of healthcare delivery within the European field of human reproduction and embryology. This guideline represents the views of ESHRE, which were achieved after careful consideration of the scientific evidence available at the time of preparation. In the absence of scientific evidence on certain aspects, a consensus between the relevant ESHRE stakeholders has been obtained. The aim of clinical practice guidelines is to aid healthcare professionals in everyday clinical decisions about appropriate and effective care of their patients. However, adherence to these clinical practice guidelines does not guarantee a successful or specific outcome, nor does it establish a standard of care. Clinical practice guidelines do not override the healthcare professional's clinical judgment in diagnosis and treatment of particular patients. Ultimately, healthcare professionals must make their own clinical decisions on a case-by-case basis, using their clinical judgment, knowledge, and expertise, and taking into account the condition, circumstances, and wishes of the individual patient, in consultation with that patient and/or the guardian or carer. ESHRE makes no warranty, express or implied, regarding the clinical practice guidelines and specifically excludes any warranties of merchantability and fitness for a particular use or purpose.
