Download or read book Sex Chromosomes written by Ursula Mittwoch and published by Academic Press. This book was released on 2014-06-28 with total page 317 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sex Chromosomes focuses on the study of sex chromosomes, including human chromosomal abnormalities, behavior and characteristics of chromosomes, and cell division. The book first offers information on the chromosomal basis of sex determination, as well as development of the cell theory, mitosis, fertilization, meiosis, and discovery of sex chromosomes. The publication also ponders on the mitosis, meiosis, and formation of gametes. Discussions focus on the special characteristics of sex chromosomes, abnormalities of cell division, and sexual differentiation. The manuscript reviews sex chromosomes in plants, Drosophila, and Lepidoptera. The book also examines sex-chromosome mechanisms that differ the classic type; sex chromosomes in fishes, amphibia, reptiles, and birds; and sex chromosomes in man. Discussions focus on normal human sex chromosomes, Turner's syndrome, Klinefelter's syndrome, true hermaphrodites, testicular feminization, and pseudohermaphrodites. Sex chromosomes in mammals other than man, including monotremata, marsupialia, insectivora, rodentia, and carnivora, are discussed. The publication is a dependable reference for readers interested in the study of sex chromosomes.
Download or read book The Sex Chromosome Complement is an Important Determinant in Obesity and Related Diseases written by Jenny Chen Link and published by . This book was released on 2015 with total page 172 pages. Available in PDF, EPUB and Kindle. Book excerpt: Obesity is associated with numerous metabolic disorders, including hypertension, hyperlipidemia, insulin resistance, and atherosclerosis. In addition, obesity is a risk factor for cardiovascular disease and cancer, the leading causes of mortality. It is thus critical to understand the environmental and genetic components that contribute to the development of obesity, one of which is sex. The sexual dimorphism in fat accumulation and distribution has been well established for a few decades. Premenopausal women tend to gain fat near the hips and thighs, while men and postmenopausal women tend to accumulate fat in the abdominal cavity. These sex differences have often been attributed to sex hormones, but sex differences in metabolic traits remain long after gonadal hormones have declined. This suggests that factors other than sex hormones could contribute to sex differences in metabolism. The sex chromosome complement is the fundamental difference between male and female cells. Because XX chromosomes often coexist with ovaries and XY chromosomes are coupled with testes, the distinct effects of gonadal type and sex chromosomes are difficult to distinguish. A unique mouse model called the Four Core Genotypes (FCG) generates XX female, XX male, XY female, and XY male mice, and is an innovative tool to study effects of the sex chromosome complement (XX male/female vs. XY male/female) independently from effects of gonadal hormones (XX/XY male vs. XX/XY female). We used FCG mice to study sex differences in obesity and related metabolic disorders. We compared gonadally intact mice with gonadectomized mice to assess acute effects of gonadal hormones, and we nutritionally challenged mice with a high fat diet and a high cholesterol diet to identify diet-sex interactions. Male and female mice with two X chromosomes gain more weight, have increased adiposity, and accumulate more hepatic lipid compared to XY mice. In addition, XX mice have increased HDL cholesterol levels, regardless of the dietary or hormone milieu. Sex chromosome differences were also detected at the molecular level, modulating mRNA and microRNA expression. Our studies demonstrate that the sex chromosome complement is a major determinant of body weight, adiposity, and associated metabolic traits such as hepatic lipid and plasma lipid levels. The key findings from this dissertation will shed light on sex differences in obesity and are important for improving prevention and treatment of metabolic disease.
Download or read book Exploring the Biological Contributions to Human Health written by Institute of Medicine and published by National Academies Press. This book was released on 2001-07-02 with total page 287 pages. Available in PDF, EPUB and Kindle. Book excerpt: It's obvious why only men develop prostate cancer and why only women get ovarian cancer. But it is not obvious why women are more likely to recover language ability after a stroke than men or why women are more apt to develop autoimmune diseases such as lupus. Sex differences in health throughout the lifespan have been documented. Exploring the Biological Contributions to Human Health begins to snap the pieces of the puzzle into place so that this knowledge can be used to improve health for both sexes. From behavior and cognition to metabolism and response to chemicals and infectious organisms, this book explores the health impact of sex (being male or female, according to reproductive organs and chromosomes) and gender (one's sense of self as male or female in society). Exploring the Biological Contributions to Human Health discusses basic biochemical differences in the cells of males and females and health variability between the sexes from conception throughout life. The book identifies key research needs and opportunities and addresses barriers to research. Exploring the Biological Contributions to Human Health will be important to health policy makers, basic, applied, and clinical researchers, educators, providers, and journalists-while being very accessible to interested lay readers.
Download or read book Sex Chromosomes written by Cynthia N. Weingarten and published by Nova Science Publishers. This book was released on 2009 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sex chromosomes determine the sex of an organism. A human somatic cell has two sex chromosomes: XY in male and XX in female. A human germ cell has one sex chromosome: X or Y in a sperm and X in an egg. When an X-sperm is combined with an egg, the resulting zygote (fertilised egg) will contain two X chromosomes. A person developed from the XX-zygote will have the characteristics of a female. Combination of a Y-sperm and an egg will produce a male. Usually, a woman has two X chromosomes (XX) and a man one X and one Y (XY). However, both male and female characteristics can sometimes be found in one individual, and it is possible to have XY women and XX men. Analysis of such individuals has revealed some of the molecules involved in sex determination, including one called SRY, which is important for testis formation. SRY (which stands for sex-determining region Y gene) is found on the Y chromosome. In the cell, it binds to other DNA and in doing so distorts it dramatically out of shape. This alters the properties of the DNA and likely alters the expression of a number of genes, leading to testis formation. Most XX men who lack a Y chromosome do still have a copy of the SRY gene on one of their X chromosomes (moved there by chromosomal translocation). This copy accounts for their maleness. However, because the remainder of the Y chromosome is missing they frequently do not develop secondary sexual characteristics in the usual way. This book presents the latest research in the field from around the world.

Available in PDF, EPUB and Kindle. Book excerpt: Gigantism and Acromegaly brings together pituitary experts, taking readers from bench research, to genetic analysis, clinical analysis, and new therapeutic approaches. This book serves as a reference for growth hormone over-secretion and its diagnosis and treatment for endocrinologists, pediatricians, internists, and neurosurgeons, and for geneticists. Pharmaceutical companies may use it as a reference for drug development and research. Students, residents and fellows in medicine and endocrinology and genetics will also find it valuable as it provides a single up-to-date review of the molecular biology of gigantism and acromegaly as well as recommended approaches to evaluation and management. Acromegaly is a rare pituitary disorder that slowly changes its adult victim's appearance over time: larger hands and feet, bigger jaw, forehead, nose, and lips. Generally, a benign pituitary tumor is the cause and symptoms of acromegaly can vary from patient to patient, making a diagnosis difficult and prolonging suffering for years. Early detection is key in the management of acromegaly as the pathologic effects of increased growth hormone (GH) production are progressive and can be life-threatening as the result of associated cardiovascular, cerebrovascular, and respiratory disorders and malignancies. - Accessible, up-to-date overview of the characteristics, state-of-the-art diagnostic procedures, and management of acromegaly and gigantism - Provides a unique compendium of endocrinology, genetics, clinical diagnosis and therapeutics - Contains contributions from internationally known experts who have treated patients with acromegaly and gigantism
