The Quaternary comprises a brief time in the Earth s history and apart from a few exceptions molluscan…
assemblages recovered from exposures along the coast of Southwestern South America Southern Brazil Uruguay Argentina are essentially the same than those that inhabit the region today leading to the assumption that no important change in the distribution of the faunas since Pleistocene times has occurred However the good taxonomic and temporal resolution reached in the last years allowed us to detect some biogeographic changes although traditional biogeographic units remain the same i e Magellanic and Argentinean Provinces These modifications involve mainly variations in the taxonomic composition of the assemblages and in the southern boundaries of some species distributions extralimital species today retracted northwards These changes are related to southward shifts of the warm waters of the Brazilian Current correlated with global warm peaks This phenomenon was more intense in the Late Pleistocene MIS 5e and in the Holocene between ca 6500-3500 14C yrKeratoconjunctivitis Sicca and Filamentary Keratopathy
By Helena M. Tabery. 2011
This book presents in vivo captured high-magnification images of two conditions: keratoconjunctivitis sicca (KCS, or dry eye), an extremely common…
disease of the ocular surface, and filamentary keratopathy, a relatively rare phenomenon most commonly associated with KCS. The images of KCS represent the broad spectrum of ocular surface changes seen in the condition while the images of filamentary keratopathy clearly reveal the components of the ocular surface appendices, termed filaments. The photographs show phenomena captured in various illumination modes, without staining and after staining with diagnostic dyes, and the photographic sequences illustrate their dynamics. The images reflect the in vivo situation. Once aware of the various phenomena, anyone working with standard diagnostic equipment - the slit lamp and the diagnostic dyes- will be able to detect almost all of them. The book will be invaluable for all who deal with ocular surface diseases.Orbital Tumors

By Carlos Pavesio. 2017
This book offers a concise but comprehensive overview of scleritis, with up-to-date information on all aspects, including diagnosis and treatment.…
Fundamental features of the pathogenesis of scleral inflammation are first discussed as a basis for understanding the therapeutic strategies. Detailed descriptions are then provided of clinical manifestations, the complications that can arise during the course of the disease process, and the best way to manage them. An individual chapter is devoted to infectious scleritis and its management, this being an uncommon but serious condition that may result not only in loss of vision but also in loss of the globe itself. The diagnostic approach to and various management options for scleritis are then discussed extensively, with coverage of local and systemic therapy and new strategies, including biologics. Apart from the potential impact on vision, inflammation of the sclera carries a risk of association with systemic diseases, some of which can prove fatal if not promptly recognized and managed. This book is designed to allow ophthalmologists to easily identify the condition and the signs indicative of a more severe problem. It will thereby assist in safe and effective management, and help in preserving vision and life.Evolution of the Vertebrate Ear

By Matthew Campbell, G. Jane Farrar, Lawrence C. Tam, Marian M. Humphries, Pete Humphries, Anna-Sophia Kiang, Paul F. Kenna. 2012
The hereditary retinopathy, retinitis pigmentosa (RP), which affects 1 in 3,500 people worldwide, is the most common cause of registered…
visual handicap among those of the working age in developed countries. RP is a highly variable disorder where patients may develop symptomatic visual loss in early childhood, while others may remain asymptomatic until mid-adulthood. Most cases of RP segregate in autosomal dominant, recessive or X-linked recessive modes, with approximately 41 genes being implicated in disease pathology to date (RetNet). The extensive genetic heterogeneity associated with autosomal dominant RP (adRP) is an undisputed hindrance to the development of genetically based therapeutics.The Sclera
