Several discoveries are noteworthy for allowing us to probe the recesses of the virus- infected cell and to search for cryptic viral genomes which might provide clues in our studies of cancer etiology or developmental biology.
No one has counted the enzymes in the human organism, and probably their profuse number can only be estimated from the restrictions the finite mass of genetic material imposes.
During recent years enzyme histochemical reactions have increasingly been considered as important, the reason being that enzyme histo- chemistry is now a well-established link between morphology and bio- chemistry.
The plan for this atlas evolved from the necessity of providing the biology student interested in protozoology, cytology, and para- sitology with an introduction to the study of fine structure in Protozoa.
For over 30 years I have been engaged as a parasitolo- nitz, Springer-Verlag, Heidelberg, was arranged in the pres- gist in research on endemic diseases in our land.
With the introduction of antibiotics acute inflammatory disease has ceased to be the dominant problem in general medical practice and its place is now increasingly occupied by chronic inflamma- tory disease of which the rheumatic diseases constitute the most important group.
Despite the amazing progress made by the stereotactic technique, particularly regarding the localization of the target, despite the extreme caution, which stereotactic neurosurgeons apply at every step of the procedures, despite the routine roentgenologic and physiologic controls (depth EEG, electric stimulation) preceding the production of a lesion, there remains a certain degree of uncertainty regarding the position, shape and extent of the lesion as well as of the electrode track and also regarding unintended lesions in the vicinity.
Immunology, in all its facets of immunochemistry, humoral immunity, cellular immunity, immunodiagnosis, and immunotherapy, is currently the most rapidly advancing discipline of clinical and experimental oncology.
The early development of the mammalian embryo belongs to a period which, for the student, provides the particularly deep fascination connected with the processes of germination of the fIrst tender buds of life.
GOETHE bemerkt in seinen "Maximen und Reflexionen": "Zur Verewigung des Irrtums tragen die Werke besonders bei, die enzyklopädisch das Wahre und Falsche des Tages überliefern.
This Atlas is one of a series devoted to neurosurgical and neuro- logical conditions and is complementary to Atlas of the Histology of Brain Tumors (Springer-Verlag, Berlin-Heidelberg-New York 1971), which was the first in the atlas series.
The International Life Sciences Institute (ILSI), a nonprofit, public foundation, was established in 1978 to advance the sciences of nutrition, toxicology, and food safety.
The secretion of bioactive products by tumors of the gastroenteropancreatic system results in the development of watery diarrhea that can lead to death in a very short period if not brought under control.
