The heterotetrameric AP-1 complex is involved in the formation of clathrin-coated vesicles at the trans-Golgi network (TGN) and interacts with sorting signals in the cytoplasmic tails of cargo molecules. Targeted disruption of the mouse mu1A-adaptin gene causes embryonic lethality at day 13.5. In cells deficient in micro1A-adaptin the remaining AP-1(More)
The afferent and efferent connections of the prelunate visual association area V4 of macaque monkeys were investigated by means of the horseradish peroxidase (HRP) method. The specific thalamic afferents from the dorsolateral segment of the medial pulvinar and the lateral segment of the inferior pulvinar were topographically organized. A band of cells was(More)
A reduced silver technique using physical development to stain embryonic nervous tissue is described. Brains are fixed in Bodian's fixative. Paraffin sections are pretreated with 1% chromic acid or 5% formol. They are impregnated with 0.01% silver nitrate dissolved in 0.1 M boric acid/sodium tetraborate buffer of pH 8 or with silver proteinate. Finally they(More)
The distribution, form variability and organization of two types of encapsulated mechanoreceptors, the Grandry and the Herbst corpuscles, were studied in the beak of geese. (1) In the beak skin Grandry corpuscles were found 20 to 150 μ below the epidermis in the domestic goose (Anser anser) and 1 to 80 μ deep in the white-fronted goose (Anser albifrons).(More)
Glucoseinjektionen (0,33 g/kg Körpergewicht in 15 sec) und Arginin-Infusionen (0,5 g/kg Körpergewicht in 30 min) bei Neugeborenen verschiedenen Alters (1–2, 4 und 7 Tage) führten zum Anstieg des STH im Blut und zur Abnahme der freien Fettsäuren und des Glycerins. Die stärkste STH-Reaktion wurde bei den jüngsten Neugeborenen (1–2 Tage alt) beobachtet.(More)
