Vitiligo
Vitiligo is an acquired pigmentary skin disorder caused by the absence of pigmentary cells from the epidermis that results in white macules and patches on the body. Initial lesions occur most frequently on the hands, forearms, feet, and face, favoring a periocular or perioral distribution. The course of the disease is often unpredictable and varies in response to the treatment. Depigmentation often the cause of psychological distress, social stigmatization, and low self-esteem...
Visual Transduction and Non-Visual Light Perception
Remarkable advances have contributed to revolutionizing the study of vertebrate vision. The first step to identifying objects and establishing spatial relationships is the visual transduction cascade, a process that underpins a wide range of ocular diseases and therapies. Toward that, Visual Transduction And Non-Visual Light Perception reveals not only how the eye evolved into an organ of vision, but also describes how molecular mechanisms of key molecules (such as transducins, phosphodiesterases, and CyclicGMP metabolizing enzymes) operate in the phototransduction cascade. In this groundbreaking text, experts also explain mechanisms for sensing readiation outside of the visible wavelengths -- a good example of the limitations of the human sensory systems. Comprehensive and penetrating, Visual Transduction And Non-Visual Light Perception brings together the developmental, structural, and molecular mechanisms of the visual transduction cascade and is an invaluable text for everyone conducting research in the visual system.

Surgical Ophthalmic Oncology : A Collaborative Open Access Reference
Designed as an easy-to-use, practical guide to tumors of the eye, lids, and orbit, this Open Access book comprehensively addresses surgical treatment and management of diseases related to ophthalmic oncology.this book includes considerations for those ophthalmologists offering subspecialty care in environments with limited access to advanced technology and instrumentation. Individual chapters address diagnostic indications, pre-operative and post-operative concerns, and provide detailed explanations of surgical techniques required to manage various eye cancer ailments with help of ample illustrations. The book concludes with a section on ophthalmic pathology which details essential guidelines on relevant aspects from specimen collection and transport, to interpretation of the pathology report.
Surgical management of inflammatory eye disease
Ocular inflammation presents a broad spectrum of clinical manifestations. Inflammatory activity can often be managed by drug therapy. However, inadequate medical therapy may permit the development of various complications in the eye that cannot be sufficiently treated pharmacologically. Whereas drug management demands an interdisciplinary approach with well-trained specialists, surgical treatment of ocular complications due to inflammation requires an experienced surgeon. This book offers evidence-based information and a step-by-step guide on all relevant surgical procedures, which is otherwise rare to find.
Star Clusters and How to Observe Them
Part one of this detailed book provides a comprehensive review of star clusters – including open, globular, extragalactic, and even cluster remnants – along with their evolution and physics. Part two is about observing. The larger clusters can be observed through the most basic equipment – normal binoculars or budget telescopes – but Mark Allison talks about instrumentation and accessories, for observers from beginner to expert. Finally there is an observing guide and a comprehensive observing list for a wide range of telescope apertures.
Skeletal muscle stem cells : Methods and protocols
Looks at the latest technologies and methods--combined with new genetic tools available in animal models--used in this constantly evolving field. The chapters in this book are organized into three sections: Section one covers muscle stem cells and progenitor cells; Section Two discusses animal models for muscle stem cells and regeneration; and Section Three explores bioinformatics and imaging analysis for muscle stem cells. Written in the highly successful Methods in Molecular Biology series format, chapters include introductions to their respective topics, lists of the necessary materials and reagents, step-by-step, readily reproducible laboratory protocols, and tips on troubleshooting and avoiding known pitfalls.
Robots and autonomous machines for agriculture production
In recent years, due to the improved performance of artificial intelligence, precision agriculture, and advanced control, they have been widely used in various agricultural applications, including management, disease detection, crop monitoring, yield estimation, and crop harvesting. Robotics and autonomous machines represent a high-level application of automation in agriculture, based on precise and resource-efficient approaches to sustainably achieve greater efficiency and quality in the production of agricultural products while reducing environmental impact. Reactive technologies based on agricultural robots and autonomous machines are separate but closely related fields covering the application of automated control and robotic platforms at all levels of agricultural production. In robotic or autonomous systems, agricultural sensing and control is particularly difficult due to the complexity of the environment in which agricultural production operates.

Red eye syndrome
Red eye is the cardinal sign of ocular inflammation. The condition is usually benign and can be managed by primary care physicians. Conjunctivitis is the most common cause of red eye. Other common causes include blepharitis, corneal abrasion, foreign body, subconjunctival hemorrhage, keratitis, iritis, glaucoma, chemical burn, and scleritis. Signs and symptoms of red eye include eye discharge, redness, pain, photophobia, itching, and visual changes. Generally, viral and bacterial conjunctivitis are self-limiting conditions, and serious complications are rare. Because there is no specific diagnostic test to differentiate viral from bacterial conjunctivitis, most cases are treated using broad-spectrum antibiotics. Allergies or irritants also may cause conjunctivitis.

Ophthalmologic Drug Guide
Ophthalmology has long been considered a surgical area because so many disorders/diseases are treated surgically rather than medically. In the past ten years, however, there have been considerable therapeutic breakthroughs in non-surgical treatments. For instance, anti-glaucoma agents have becoming increasingly effective. This edition will include a new chapter for retinal disease. There are now several pharmaceutical agents being used to treat these diseases. Specifically, age-related macular degeneration has many new products – macugen, lucentis, etc. – and intraocular infections are primarily treated with intravitreal medications. Additionally, the anti-allergy and dry eye markets have grown tremendously in the last 2-3 years (endura, restasis, xibrom, etc).
