| diagram of hair follicle: Nanoscience in Dermatology Michael R. Hamblin, Pinar Avci, Tarl Prow, 2016-08-13 Nanoscience in Dermatology covers one of the two fastest growing areas within dermatological science, nanoscience and nanotechnology in dermatology. Recently, great progress has been made in the research and development of nanotechnologies and nanomaterials related to various applications in medicine and, in general, the life sciences. There is increasing enthusiasm for nanotechnology applications in dermatology (drug delivery, diagnostics, therapeutics, imaging, sensors, etc.) for understanding skin biology, improving early detection and treatment of skin diseases, and in the design and optimization of cosmetics. Light sensitive nanoparticles have recently been explored, opening a new era for the combined applications of light with nanotechnology, also called photonanodermatology. However, concerns have been raised regarding the adverse effects of intentional and unintentional nanoparticle exposure and their toxicity. Written by experts working in these exciting fields, this book extensively covers nanotechnology applications, together with the fundamentals and toxicity aspects. It not only addresses current applications of nanotechnology, but also discusses future trends of these ever-growing and rapidly changing fields, providing scientists and dermatologists with a clear understanding of the advantages and challenges of nanotechnology in skin medicine. - Provides knowledge of current and future applications of nanoscience and nanotechnology in dermatology - Outlines the fundamentals, methods, toxicity aspects, and other relevant aspects for nanotechnology based applications in dermatology - Coherently structured book written by experts working in the fields covered |
| diagram of hair follicle: Aging Hair Ralph M. Trüeb, Desmond Tobin, 2010-04-02 “Aged? But he does not appear aged, just look, his hair has remained young!” Marcel Proust, In Search of Lost Time (1913–27) The appearance of hair plays an important role in peoples’ overall physical appe- ance and self-perception. With today’s increasing life-expectation, the desire to look youthful plays a bigger role than ever. The hair care industry has become aware of this, and capable to deliver active products that are directed toward meeting this c- sumer demand. The discovery of pharmacological targets and the development of safe and effective drugs such as minoxidil and fnasteride also indicate strategies of the drug industry for maintenance of healthy and beautiful hair in the young and old. The study of hair aging focuses on two main streams of interest: On the one hand, the esthetic problem of aging hair and its management, in other words everything that happens outside the skin; on the other hand, the biological problem of aging hair, in terms of microscopic, biochemical, and molecular changes, in other words the “secret life” of the hair follicle in the depth of the skin. Hair aging comprises hair shaft aging, and aging of the hair follicle. The former involves weathering and photoaging of the hair shaft, while the latter manifests as decrease of melanocyte function (graying) and decrease in hair production (alopecia). |

| diagram of hair follicle: Photomedicine and Stem Cells Heidi Abrahamse, Michael R Hamblin, 2017-12-20 Janus, the ancient Roman god depicted with two faces is an appropriate metaphor for light therapy. In the right photodynamic therapy conditions, light is able to kill nearly anything that is living such as cancers, microorganisms, parasites, and more. On the opposite face, light of the correct wavelength and proper dose (photobiomodulation) can heal, regenerate, protect, revitalize and restore any kind of dead, damaged, stressed, dying, degenerating cells, tissue, or organ system. This book discusses both sides of Janus' face in regards to light therapy. |

| diagram of hair follicle: Immunology of the Skin Kenji Kabashima, 2016-03-10 This book reviews the role of each cell subset in the skin, providing the basics for understanding skin immunology and the mechanisms of skin diseases. The skin is one of the immune organs and is continually exposed to foreign antigens and external stimuli that must be monitored and characterized for possible elimination. Upon exposure to foreign antigens, the skin can elicit a variety of immune responses in harmony with skin components that include keratinocytes, dendritic cell subsets, mast cells, basophils, fibroblasts, macrophages, gamma-delta T cells, neutrophils, myeloid-derived suppressor cells, vascular and lymphatic cells, hair follicles, platelets, and adipose tissues, among others. In the past 10 years, knowledge of immunology has expanded drastically in areas such as innate immunity (Toll-like receptors, C-type lectins), and host defenses to bacteria and viruses, and this increased knowledge has led to the development of more effective treatment of psoriasis and other skin diseases. This book provides updates on the mechanisms of skin diseases including contact dermatitis, atopic dermatitis, psoriasis, urticaria, drug eruption, bullous diseases, anaphylaxis, graft-versus-host disease, rosacea, lymphoma, photodermatology, and collagen vascular diseases. Understanding the basics of skin immunology will help clinicians and dermatologists use new therapeutics such as biologics efficiently. Serving as an intermediary between basic science and clinical medicine, this book gives readers the opportunity to understand and marvel at the mystery and fascination of skin immunology. |

| diagram of hair follicle: A Practical Guide To The Forensic Examination Of Hair James R. Robertson, Elizabeth Brooks, 2021-10-21 A Practical Guide to the Forensic Examination of Hair: From Crime Scene to Court presents current best practices and methodologies for forensic microscopists and trace evidence analysts, in addition to lawyers and judges, to detail the utilisation of hair evidence in court cases. The 30-year evolution and development of forensic DNA analysis has placed very heavy focus on its value in identifying the source of biological materials in other evidence. In addition to some recent controversies over the reliability of hair evidence and analysis, the question arises: what to do with hairs and hair evidence presented in court cases? The reality is that this is a fairly common form of evidence present at, and relevant in, many types of crime scenes and scenarios. Are we to simply ignore hairs as an evidence type? This book outlines the case for hair evidence’s continued relevance as a valuable biological source that can contribute to assisting in answering questions of identity and questions of what happened or the criminalistic potential of hairs. The authors present a four-level approach to the case management of recovered hairs. This system, which can be incorporated into contemporary forensic practice, stresses the need for thorough and systematic recording of hairs and their microscopic features and on the need to focus on differences to effectively triage recovered hairs. The approach focuses on the efficient and accurate selection of hairs for nuclear and mitochondrial DNA analysis while addressing the criminalistic potential of hairs. Key Features: Outlines the latest advances in the collection and forensic hair fibres, and includes full-colour illustrative figures throughout. Covers the advances in DNA extraction and analysis of hair samples including nuclear and mt-DNA testing. Addresses all forensic aspects of hair evidence including recovery, collection, examination, analysis, testing and presentation of such results in court. A Practical Guide to the Forensic Examination of Hair is a practical reference written for practitioners and promotes the need for quality assurance measures, process standardization and proficiency testing to ensure the scientific reliability of hair examination. The book discusses how to interpret and report on hair findings to impart to investigators, and to the broader legal system, the appropriate weight that should be attributed to hair findings. It provides invaluable methodologies and guidelines that reinforce the ongoing value and validity of hair examinations. |

Rizk, 2015-06-25 A practical approach to the field of androgen excess or deprivation in women's health. The content includes multiple viewpoints on the most common disorders in this class, such as polycystic ovary disease, hirsutism and menopausal issues. Each chapter provides a combination of long-lasting clinical principles in the diagnosis and management of these patients along with a state-of-the-art review. This text takes an innovative approach to uncommon conditions (such as congenital adrenal hyperplasia, transgender conditions). In addition to presenting clinical insights, and a review of the basic science underpinning these conditions, it focuses on key concepts that can be derived from these rare conditions to the entire field. This book is an essential addition to the library for any busy clinician who is looking for a practical reference guide but also for the sub-specialist who is looking for new and thought-provoking insights in this complex scientific area. |
| diagram of hair follicle: Epigenetics and Dermatology Qianjin Lu, Christopher Chang, Bruce C. Richardson, 2015-02-16 Epigenetics and Dermatology explores the role of epigenetics in the pathogenesis of autoimmune-related skin diseases and skin cancer. Leading contributors cover common and uncommon skin conditions in which extensive epigenetic research has been done. They explain how environmental exposures (chemicals, drugs, sunlight, diet, stress, smoking, infection, etc.) in all stages of life (from a fetus in-utero to an elderly person) may result in epigenetic changes that lead to development of some skin diseases in life. They also discuss the possibilities of new and emergent epigenetic treatments which are gradually being adopted in management of various skin diseases. Chapters follow a conventional structure, covering fundamental biology of the disease condition, etiology and pathogenesis, diagnosis, commonly available treatments, and epigenetic therapy where applicable. Discusses the basic biology of skin diseases and skin cancers induced or aggravated by aberrant epigenetic changes Evaluates how to approach autoimmune-related skin diseases from a therapeutic perspective using the wealth of emergent epigenetic clinical trials Offers a coherent and structured table of contents with basic epigenetic biology followed by discussion of the spectrum of rheumatologic through neoplastic skin diseases, finally ending with a discourse on epigenetic therapy |
