- BookStephen H. Tsang, Taurn Sharma [editors].Summary: "This Atlas of Inherited Retinal Disorders provides a thorough overview of various inherited retinal dystrophies with emphasis on phenotype characteristics and how they are related to the most frequently encountered genes. It will also meet the hitherto unmet need of PhD students who would benefit from seeing the phenotypes of the genes they work on and study. Further, because it would help geneticists use and familiarize themselves with the candidate gene approach to test patients' genomes, enabling them to test more efficiently and cost-efficiently (as the cost of genetic testing is quite high and spiralling higher). This invaluable atlas is organized into eight sections starting with the basic knowledge on retinal imaging as an introduction to the subject matter, then diseases are listed according to their inheritance pattern while disorders with extraocular manifestations are grouped by their defining features. This structure will be intuitive to clinicians and students studying IRDs"--Publisher's description.

Genetic testing for inherited retinal dystrophy: basic understanding.Digital Access Springer 2018 - ArticleFiedler H, Schäfer H, Köhler E, Knospe S, Hahn HJ, Ziegler B, Gottschling HD, Heinke P.Endokrinologie. 1977;70(3):301-20.Colony-bred sand rats were fed with rat pellet chow in restricted quantities or ad libitum for 8--10 or 28--31 weeks after weaning. The changes of glucose metabolism were characterized by an intraperitoneal glucose tolerance test. The daily food intake and the average weight gain differed only in the first 5--7 weeks of pellet nutrition. In the impaired glucose tolerance tests of all sand rats the high basal plasma IRI levels were not significantly increased by the grossly enhanced blood glucose concentrations. The insulin secretion of either acutely incubated or for 8 days cultivated isolated pancreatic islets, however, was stimulated already by low (1.7 and 5 mM) glucose concentrations in all diet groups. Otherwise the glucagon secretion of isolated islets was not suppressed by high glucose concentrations. No changes of insulin or glucagon contents of islets were found in the different diet groups. The adipocytes of all animals revealed a complete ineffectiveness of insulin on the glucose utilization to CO2 and triglycerides. The basal glucose conversion to CO2 and glycogen in skeletal muscle and the stimulatory potency of insulin was low and not distinctly different in all groups. In liver glycogen and triglyceride contents as well as gluconeogenic enzyme activities were not influenced by feeding of different quantities of pellet diet at the investigated time points. The time course of the metabolic and clinical alterations demonstrates that the peripheral organs become insensitive to insulin in the first weeks after weaning.
