Book Synopsis New Mechanisms for Tissue-Selective Estrogen-Free Contraception by : H.B. Croxatto
Download or read book New Mechanisms for Tissue-Selective Estrogen-Free Contraception written by H.B. Croxatto and published by Springer Science & Business Media. This book was released on 2007-01-19 with total page 273 pages. Available in PDF, EPUB and Kindle. Book excerpt: Combined oral contraceptives are the most convenient and accepted method of hormonal contraception. Nevertheless, the medical community and consumers constantly demand innovation, additional benefits during use and lower hormonal load despite the high safety profile of available products. At the Ernst Schering Research Foundation Workshop 52, new perspectives and mechanisms for tissue-selective, estrogen-free contraception were discussed. The aim of the workshop was to bring together experts in the field of molecular and pharmacodynamic action of progestins with clinicians and medical experts to discuss potential medical endpoints, physiological reactions and (bio)marker useful describing the tissue selectivity and the contraceptive action of new progestins in different target organs. A major factor for successful realization of these new concepts is a deeper understanding of local pharmacological responses to progestins in general and to new progestins in particular.

Download or read book Contraceptive Research and Development written by Institute of Medicine and published by National Academies Press. This book was released on 1996-11-04 with total page 534 pages. Available in PDF, EPUB and Kindle. Book excerpt: The "contraceptive revolution" of the 1960s and 1970s introduced totally new contraceptive options and launched an era of research and product development. Yet by the late 1980s, conditions had changed and improvements in contraceptive products, while very important in relation to improved oral contraceptives, IUDs, implants, and injectables, had become primarily incremental. Is it time for a second contraceptive revolution and how might it happen? Contraceptive Research and Development explores the frontiers of science where the contraceptives of the future are likely to be found and lays out criteria for deciding where to make the next R&D investments. The book comprehensively examines today's contraceptive needs, identifies "niches" in those needs that seem most readily translatable into market terms, and scrutinizes issues that shape the market: method side effects and contraceptive failure, the challenge of HIV/AIDS and other sexually transmitted diseases, and the implications of the "women's agenda." Contraceptive Research and Development analyzes the response of the pharmaceutical industry to current dynamics in regulation, liability, public opinion, and the economics of the health sector and offers an integrated set of recommendations for public- and private-sector action to meet a whole new generation of demand.

Book Synopsis Hormonal Contraception and Post-menopausal Hormonal Therapy by : IARC Working Group on the Evaluation of Carcinogenic Risks to Humans
Download or read book Hormonal Contraception and Post-menopausal Hormonal Therapy written by IARC Working Group on the Evaluation of Carcinogenic Risks to Humans and published by World Health Organization. This book was released on 1999 with total page 692 pages. Available in PDF, EPUB and Kindle. Book excerpt: Evaluates evidence for an increased risk of cancer in women using combined oral contraceptives, progestogen-only hormonal contraceptives, post-menopausal estrogen therapy, and post-menopausal estrogen-progestogen therapy. Although the carcinogenicity of these preparations has been extensively investigated, the book stresses the many complex methodological issues that must be considered when interpreting findings and weighing results. Evidence of an association between use of these preparations and positive effects on health, including a reduced risk of some cancers, is also critically assessed. The first and most extensive monograph evaluates evidence of an association between the use of combined oral contraceptives and cancer at nine sites. Concerning breast cancer, the evaluation concludes that, even if the association is causal, the excess risk for breast cancer associated with patterns of use that are typical today is very small. Studies of predominantly high-dose preparations found an increased risk of hepatocellular carcinoma in the absence of hepatitis viruses. Citing these findings, the evaluation concludes that there is sufficient evidence in humans for the carcinogenicity of combined oral contraceptives. The evaluation also found sufficient evidence for the carcinogenicity of some, but not all, combined preparations in animals. Combined oral contraceptives were classified as carcinogenic to humans. The evaluation also cites conclusive evidence that these agents have a protective effect against cancers of the ovary and endometrium. Progestogen-only contraceptives are evaluated in the second monograph, which considers the association with cancer at six sites. The evaluation found no evidence of an increased risk for breast cancer. Although the evaluation found sufficient evidence in animals for the carcinogenicity of medroxyprogesterone acetate, evidence for the carcinogenicity of progestogen-only contraceptives in humans was judged inadequate. Progestogen-only contraceptives were classified as possibly carcinogenic to humans. The third monograph, on post-menopausal estrogen therapy, considers evidence of an association with cancer at eight sites. Findings from a large number of epidemiological studies indicate a small increase in the risk of breast cancer in women who have used these preparations for five years or more. Studies consistently show an association between use of post-menopausal estrogen therapy and an increased risk for endometrial cancer. Data on the association with other cancers were either inconclusive or suggested no effect on risk. The evaluation concludes that post-menopausal estrogen therapy is carcinogenic to humans. The final monograph evaluates the association between the use of post-menopausal estrogen-progestogen therapy and cancer at four sites. The evaluation of limited data on breast cancer found an increased relative risk observed with long-term use. Data were judged insufficient to assess the effects of past use and of different progestogen compounds, doses, and treatment schedules. For endometrial cancer, the evaluation found an increase in risk relative to non-users when the progestogen was added to the cycle for 10 days or fewer. Post-menopausal estrogen-progestogen therapy was classified as possibly carcinogenic to humans. Concerning post-menopausal therapy in general, the book notes that evidence of carcinogenic risks must be placed in perspective of potential benefits. The prevention of osteoporotic fractures is cited as the best-established benefit. Evidence also suggests that estrogen prevents heart disease and may prevent memory loss and dementia.

Download or read book PET Chemistry written by P.A. Schubiger and published by Springer Science & Business Media. This book was released on 2007-01-19 with total page 348 pages. Available in PDF, EPUB and Kindle. Book excerpt: Personalized medicine employing patient-based tailor-made therapeutic drugs is taking over treatment paradigms in a variety of ?elds in oncology and the central nervous system. The success of such therapies is mainly dependent on ef?cacious therapeutic drugs and a selective imaging probe for identi?cation of potential responders as well as therapy monitoring for an early bene?t assessment. Molecular imaging (MI) is based on the selective and speci?c interaction of a molecular probe with a biological target which is visualized through nuclear, magnetic resonance, near infrared or other methods. Therefore it is the method of choice for patient selection and therapy monitoring as well as for speci?c e- point monitoring in modern drug development. PET (positron emitting tomography), a nuclear medical imaging modality, is ideally suited to produce three-dimensional images of various targets or processes. The rapidly increasing demand for highly selective probes for MI strongly pushes the development of new PET tracers and PET chemistry. ‘PET chemistry’ can be de?ned as the study of positron-emitting compounds regarding their synthesis, structure, composition, reactivity, nuclear properties and processes and their properties in natural and - natural environments. In practice PET chemistry is strongly in?uenced by the unique properties of the radioisotopes used (e. g. , half-life, che- cal reactivity, etc. ) and integrates scienti?c aspects of nuclear-, organic-, inorganic- and biochemistry.
Book Synopsis The Histone Code and Beyond by : Shelley L. Berger
Download or read book The Histone Code and Beyond written by Shelley L. Berger and published by Springer Science & Business Media. This book was released on 2007-01-19 with total page 223 pages. Available in PDF, EPUB and Kindle. Book excerpt: Methylation of DNA at cytosine residues as well as post-translational modifications of histones, including phosphorylation, acetylation, methylation and ubiquitylation, contribute to the epigenetic information carried by chromatin. These changes play an important role in the regulation of gene expression by modulating the access of regulatory factors to the DNA. The use of a combination of biochemical, genetic and structural approaches has allowed demonstration of the role of chromatin structure in transcriptional control. The structure of nucleosomes has been elucidated and enzymes involved in DNA or histone modifications have been extensively characterized. Since deregulation of epigenetic marks has been reported in many cancers, a better understanding of the underlying molecular mechanisms bears the promise that new drug targets may soon be found. The newest developments in this quickly developing field are presented in this book.

Book Synopsis Cytokines as Potential Therapeutic Targets for Inflammatory Skin Diseases by : R. Numerof
Download or read book Cytokines as Potential Therapeutic Targets for Inflammatory Skin Diseases written by R. Numerof and published by Springer Science & Business Media. This book was released on 2007-01-19 with total page 225 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cytokines and cytokine receptors remain an area of great interest for the development of targeted therapies for cutaneous inflammatory diseases. Anti-TNF therapeutics have proven to be effective in the treatment of psoriasis, and clinical investigations have now begun for other cytokine-directed therapies, such as those targeting IFN-g, IL-12p40, and IL-18. In addition to therapeutics that target cytokines directly, strategies that target cytokine signaling pathways are in development. This book summarizes the findings of the 56th International Workshop of the Ernst Schering Research Foundation that focused on "Cytokines as Potential Therapeutic Targets for Inflammatory Skin Diseases".

This book was released on 2007-01-19 with total page 200 pages. Available in PDF, EPUB and Kindle. Book excerpt: The therapeutic options for the treatment of Multiple Sclerosis (MS) and other neurodegenerative and traumatic diseases such as spinal cord injury, Alzheimer's, Parkinson's disease, etc. have experienced enormous progress over recent years. Despite these encouraging developments, available therapies are only partially effective, and the ultimate goal is still far from being attained. Improved understanding of the cellular and molecular mechanisms of the pathogenesis of neurodegeneration and demyelination has led to a variety of new therapeutic targets and approaches. In addition to modulation of the inflammatory process (MS) and classical neuroprotection (stroke, AD), therapeutic approaches focusing on active remyelinization and neuronal regeneration have become increasingly important. Based on current concepts, this book summarizes new therapeutic approaches.

Book Synopsis Clinical Applications of Mifepristone (RU486) and Other Antiprogestins by : Institute of Medicine
Download or read book Clinical Applications of Mifepristone (RU486) and Other Antiprogestins written by Institute of Medicine and published by National Academies Press. This book was released on 1993-02-01 with total page 303 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mifepristone (RU486), the first clinically available antiprogestin, has generated great interest since its discovery in the early 1980s. Today, it is recognized that mifepristone, along with other antiprogestins, has a potentially significant therapeutic role in human health and disease, with likely applicability to a variety of pregnancy-related conditions (e.g., management of labor) and to contraception, endometriosis, and cancer, among others. But because mifepristone has been studied and used most widely as a means of nonsurgical abortion, political issues have thus far limited research on the drug and prevented its introduction into the U.S. market. This book provides an unbiased evaluation of current knowledge about both the fundamental nature of antiprogestins as well as their possible use in treating numerous diseases and conditions, and it contains recommendations for future research.
