Available in PDF, EPUB and Kindle. Book excerpt: R. MARKS Biology has become a 'numbers game'. The advantages of being able to grade changes in tissue, submit results to statistical analysis and accurately record biological phenomena make measurement essential. This is as true for the various disciplines in applied biology as it is for the more esoteric aspects ofthe subject. Regrettably, sk in biologists until recently had not seized the opportunities that the availability of their tissue of interest afforded and fell behind in the exploration of measurement techniques. Probably this resulted in part from the mistaken sentiment that 'to see is to know'. It also originated from the complexity ofthe skin which. as a closely interwoven mixture oftissue types. makes assessments technically difficult. However, we are optimistic about the future. The International Society for Bioengineering and the Skin was formed in Cardiff in ] uly 1979 in response to the wishes of the delegates who had attended the first International Symposium on the subject in Miami in 1976 and the second in Cardiff 3 years later. This volume is the proceedings of the Cardiff meeting. We believe that it demonstrates the brave efforts and variety of new ideas that characterise the studies of scientists who realise the importance of blending the phYSICal sciences with skin biology.

This book was released on 2015-12-10 with total page 113 pages. Available in PDF, EPUB and Kindle. Book excerpt: Chronic wounds are a substantial problem in today’s health care and place significant strains on the patient. Successful modelling of the wound healing process is pivotal for the advancement of wound treatment research. Wound healing is a dynamic and multifactorial process involving all constituents of the skin. The progression from haemostasis and inflammation to proliferation of epidermal keratinocytes and dermal fibroblasts, and final scar maturation can be halted and result in a chronic wound that fails to re-epithelialise. The wound healing process constitutes an example of dynamic reciprocity in tissue where cellular changes take place on cues from the extracellular matrix and vice versa when tissue homeostasis is disturbed. The extracellular matrix provides a structural context for the resident cells and the epidermal keratinocytes, and a functioning interplay between the two tissue compartments is crucial for successful wound healing to take place. Work included in this thesis has applied viable human full thickness skin in vitro to investigate the re-epithelialisation process and barrier function of intact skin.The use of full thickness skin in vitro can take into account the contextual aspect of the process where the epidermal keratinocytes are activated and obtain a migratory phenotype, and are continuously dependent on the cues from the extracellular matrix and support of the dermis. When utilising skin for studies on re-epithelialisation, circular standardised full thickness wounds were created and cultured for up to four weeks in tissue culture. In paper I, the organisation of a thick neoepidermis was investigated in the in vitro wound healing model when resident cells were provided with a porous suspended three dimensional gelatin scaffold. In paper II we investigated the use of a fluorescent staining conventionally used for proliferation studies to facilitate the tracing of transplanted epidermal cells in in vitro wounds, in order to improve and expand the use of the model. In paper III the model was utilised to investigate the treatment approach of acidification of wounds to evaluate the suitability of such intervention in regards to keratinocyte function and re-epithelialisation. Studies on re-epithelialisation with the aid of the in vitro wound healing model provided insight in neoepidermal structure with porous gelatin scaffolding in the wound, a novel methodological approach to tracing cells and response to constrained wound healing environment. In paper IV, intact human skin was evaluated for modelling the cytotoxic response after exposure to a known irritant compound. To study barrier function, intact skin was exposed to irritants by restricting exposure topically, and full thickness skin in vitro was found suitable for modelling cytotoxicity responses. Employing human full thickness skin in vitro makes use of the actual target tissue of interest with epidermal and dermal cells, and full barrier function.

Book excerpt: This special issue entitled “Soft and hard tissue regeneration” will cover both periodontal and implant therapies. Regenerative periodontal treatment goal is to restore functional periodontal support offering a valuable treatment alternative even for teeth with large periodontal destruction, which may be successfully treated and maintained in health for long periods. In most cases where teeth are extracted for periodontal reasons, implant therapy will demand large bone augmentation procedures. Lack of sufficient bone volume may prevent placement of dental implants. In extreme cases, large bone reconstruction is indispensable before implant placement can be performed. Although, most bone grafts are only able to fill and maintain a space, where bone regeneration can occur (“osseoconductive”), the ideal bone graft will also promote osseous regeneration (“osseoinductive”). Several bone augmentation procedures have been described, each, presenting advantages and shortcomings. Success of bone augmentation procedures depends on the presence of bone forming cells, primary wound closure over the augmented area, space creation and maintenance where bone can grow and proper angiogenesis of the grafted area. Factors that influence the choice of the surgical technique are the estimated duration of surgical procedure, its complexity, cost, total estimated length of procedure until the final rehabilitations may be installed and the surgeons' experience. This special issue will have a definite clinical orientation, and be entirely dedicated to soft and hard tissue regenerative treatment alternatives, both in periodontal and implant therapy, discussing their rationale, indications and clinical procedures. Internationally renowned leading researchers and clinicians will contribute with articles in their field of expertize.

Available in PDF, EPUB and Kindle. Book excerpt: Although the history of photomedicine dates back thousands of years, with even preliterate cultures appreciating the healing properties of sunlight, for many workers in the discipline photomedicine is associated with the observation about 100 years ago of Niels Finsen, a Danish physician. Finsen recognized that people with tuberculosis who lived in Norway and who had very little exposure to sunlight often developed facial lesions (lupus vulgaris) which would decrease and sometimes disappear during the summer months. This very observant physician reasoned that artificial light ought to produce the same effect as sunlight and began utilizing the radiation from the newly available carbon arc. At first, he used a glass lens to concentrate the radiation, but since this produced considerable burning, he replaced this with a hollow glass lens filled with water. However, while this reduced the heat burns, it did not actually duplicate the effect of direct sunlight. Finally, using a hollow lens filled with water but equipped with quartz windows, Finsen was able to imitate, even improve upon, the effect of sunlight. As a result, lupus vulgaris was practically eliminated from the Scandinavian countries.

Available in PDF, EPUB and Kindle. Book excerpt: Aromas are an integral part of our civilised society. They are not only used in fine perfumes, but also in numerous other articles with which we have daily contact. Another new development has been the agricultural use of aromas as a "biological weapon" to combat insects and other pests. In the field of dermatology, aromas are today among the most frequent sensitizers and may trigger allergic contact eczemas. This volume presents numerous aspects of the topic for the first time in comprehensive form. In an introduction, the chemistry of frequently used aroma components is described, together with the art of perfume composition that has been refined over the centuries. In a chapter on neuropharmacology, the mechanisms of scent recognition are described in detail.

Book excerpt: Recent scientific breakthroughs, celebrity patient advocates, and conflicting religious beliefs have come together to bring the state of stem cell researchâ€"specifically embryonic stem cell researchâ€"into the political crosshairs. President Bush's watershed policy statement allows federal funding for embryonic stem cell research but only on a limited number of stem cell lines. Millions of Americans could be affected by the continuing political debate among policymakers and the public. Stem Cells and the Future of Regenerative Medicine provides a deeper exploration of the biological, ethical, and funding questions prompted by the therapeutic potential of undifferentiated human cells. In terms accessible to lay readers, the book summarizes what we know about adult and embryonic stem cells and discusses how to go about the transition from mouse studies to research that has therapeutic implications for people. Perhaps most important, Stem Cells and the Future of Regenerative Medicine also provides an overview of the moral and ethical problems that arise from the use of embryonic stem cells. This timely book compares the impact of public and private research funding and discusses approaches to appropriate research oversight. Based on the insights of leading scientists, ethicists, and other authorities, the book offers authoritative recommendations regarding the use of existing stem cell lines versus new lines in research, the important role of the federal government in this field of research, and other fundamental issues.

It istruly an ecological perspective helpful for undergraduate/graduatemajors in microbiology and immunology.” –AmericanSociety for Microbiology, June 2009 "Wilson provides the reader with an up-to-date, comprehensivecensus of the indigenous microorganisms that inhabit the human bodyand in so doing contributes significantly to this rapidly advancingarea of study. The narrative is clearly written; the index isexcellent; there are numerous bibliographic citations. Each chapteris rich with tables, diagrams, color micrographs, and charts… Highly recommended." –Choice Reviews "This comprehensive, yet accessible text... is an excellentand informative reference book… it should be on the shelf ofevery major science and medical library. The content, organization,and presentation make this book a unique resource."–Doody's Book Reviews Until recently, the indigenous microbiota of humans has been arelatively neglected area of microbiology with most attention beingfocused on those microbes that cause disease in humans, rather thanon those that co-exist with us in the disease-free state. However,in the past decade research has shown that not only is theindigenous microbiota involved in protecting humans from exogenouspathogens but it is also involved in our development and nutrition.Consequently, interest has grown substantially among healthprofessionals and scientists in analyzing and understanding thesemicrobial (largely bacterial) communities. This comprehensive, yet accessible text provides an up-to-dateguide to the development, composition and distribution ofindigenous microbial communities of humans. With the aid ofabundant colour figures, diagrams, tables and maps, it establisheslinks between the physicochemical factors prevailing at ananatomical site and the types of microbes to be found there. Thebook includes an introduction to the human-microbe symbiosis aswell as an in-depth look at the main systems and organs of thehuman body that have an indigenous microbiota. Each chapterincludes a list of references for further study. This is an excellent and informative reference book that isuseful to anyone with an interest in microbiology, medicalmicrobiology, microbial ecology, infectious diseases, immunology,human biology, medicine, dentistry, nursing, health sciences,biomedical sciences or pharmacy – it should be on the shelfof every major science and medical library.
