Die Universitätsbibliothek Würzburg hat für ihre umfangreiche Sammlung alter Würzburger Hochschulschriften einen Katalog erarbeitet, der hauptsächlich Dissertationen und Thesen verzeichnet, aber auch andere Prüfungsarbeiten, die für den Erwerb unterschiedlicher akademischer Grade und Titel ausgearbeitet und publiziert worden sind. Dies ist der 2. Band der Nachweise für die Jahre 1804 bis 1885 mit 2510 Titeln.
Partnerschaft und Elternschaft waren im Begriff der Familie bislang essentiell zusammengedacht: Partnerschaft und Elternschaft, Ehe und Filiation, beschreiben exklusiv und vollständig die Prinzipien, anhand derer sich das Familienpersonal rekrutiert (vgl. Tyrell 1983, S. 363). Beides muß nicht in Familien zusammenfallen. Immer mehr Ehen bleiben dauerhaft kinderlos -immer mehr Familien kommen als Ein-Elternfamilien ohne Partnerschaft aus. Das ist die sozialstrukturelle Version einer Entkoppelung von Partnerschaft und Elternschaft. Auf der anderen Seite sind Partnerschaft und Elternschaft in der überwiegenden Zahl der Fälle immer noch in Familien "fusioniert".
The total nerve cell numbers in the right and in the left human entorhinal areas have been calculated by volume estimations with the Cavalieri principle and by cell density determinations with the optical disector. Thick gallocyanin-stained serial frozen sections through the parahippocampal gyrus of 22 human subjects (10 female, 12 male) ranging from 18 to 86 years were analysed. The laminar composition of gallocyanin (Nissl)-stained sections could easily be compared with Braak's (1972, 1980) pigmentoarchitectonic study, and Braak's nomenclature of the entorhinal laminas was adopted. Cellsparse laminae dissecantes can more clearly be distinguished in Nissl than in aldehydefuchsin preparations. These cell-poor dissecantes, lamina dissecans extema (dis-ext), lamina dissecans 1 (dis-1) and lamina dissecans 2 (dis-2), were excluded from nerve cell nurober determinations. An exact delineation of the entorhinal area is indispensable for any kind of quantitative investigation. We have defined the entorhinal area by the presence of pre-alpha ceil clusters and the deeper layers of lamina principalis externa (pre-beta and gamma) separated from lamina principalis interna (pri) by lamina dissecans 1 (dis-1). The human entorhinal area is quantitatively characterized by a left-sided (asymmetric) higher pre-alpha cell number and an age-related nerve cell loss in pre as well as pri layers. At variance with other CNS cortical and subcortical structures, the neuronal number of the entorhinal area appears to decrease continuously from the earliest stages analysed, although a secular trend has to be considered. The asymmetry in pre-alpha cell number is discussed in the context of higher human mental capabilities, especially language.
The human recombination activating gene 1 (RAGl) has previously been mapped to chromosomes 14q and 11 p. Here we confirm the chromosome 11 assignment by two independent approaches: autoradiographic and fluorescence in situ hybridization to metaphase spreads and analysis of human-hamster somatic cell hybrid DNA by the polymerase chain reaction (PCR) and Southern blotting. Our results unequivocally localize RAG1 to llp13.
Spinal motoneurons innervating skeletal muscle were amongst the first neurons shown to require the presence of their target cells to develop appropriately. Isolated embryonie chick and rat motoneurons have been used to identify neurotrophic factors and cytokines capable of supporting the survival of developing motoneurons. Such factors include ciliary neurotrophic factor (CNTF), which is present physiologically in high amounts in myelinating Schwann cells of peripheral nerves, and brain-derived neurotrophic factor (BDNF) which is synthesized in skeletal muscle and, after peripheral nerve lesion. in Schwann cells. These factors have been further analyzed for their physiological significance in maintaining motoneuron function in vivo, and for their potential therapeutic usefulness in degenerative motoneuron disease. Both CNTF and BDNF are capable of rescuing injured facial motoneurons in newbom rats. Furthermore, CNTF prolongs survival and improves motor function of pmn mice, an animal model for degenerative motoneuron disease, by preventing degeneration of motoneuron axons and somata. Thus treatment of human motoneuron disease with neurotrophic factors should be possible, provided that rational means for application of these factors can be established considering also the appearance of potential side effects.
