Описание: ?This book presents results obtained from the whole mount preparations, radiological, and histological studies of 60 pu/pu and pu/+ mice from late embryo until 3 months of age. Most mice were in the embryo to 6 week age group where vertebral developmental changes are most marked. Although vertebral abnormalities have been identified as due to mutations in the delta-like 3 (Dll3) gene, it is evident that each mouse has differing structural abnormalities. The disorder is analogous to human congenital scoliosis, a common variant of which is spondylocostal dysplasia. The histological studies presented in this book include plastic embedded sections which allow for high level resolution not only of vertebrae, intervertebral discs, and ribs but also of associated spinal cord, nerve roots and ganglia. In addition an overview of embryo and neonatal development in mouse, chick and human vertebrae is provided to better assess how and where deviant pathoanatomy occurs. The book discusses the possible variables involved in creating final deformity beyond the gene abnormality itself.

Описание: The Atlas of Drosophila Morphology: Wild-type and Classical Mutants is the guide every Drosophila researcher wished they had when first learning genetic markers, and the tool they wish they had now as a handy reference in their lab research. Previously, scientists had only poor-quality images or sketches to work with, and then scattered resources online - but no single visual resource quickly at their fingertips when explaining markers to new members of the lab, or selecting flies to do their genetic crosses, or hybrids. . This alphabetized guide to Drosophila genetic markers lays flat in the lab for easy referencing. It contains high-resolution images of flies and the appropriate marker on the left side of each page and helpful information for the marker on the facing page, such as symbol, gene name, synonyms, chromosome location, brief informative description of the morphology, and comments on marker reliability. A companion website with updated information, useful links, and additional data provided by the authors complements this extremely valuable resource. . .

Описание: This 1987 book reviews and illustrates the structure, as seen by the scanning and transmission electron microscopes, of the spermatozoa of insects, centipedes, millipedes and onychophorans. Virtually every reference in the large literature on sperm ultrastructure in these groups is cited and many further observations are included.
