TL;DR: Parkinsons disease is a multisystem disorder that involves only a few predisposed nerve cell types in specific regions of the human nervous system as discussed by the authors, where the intracerebral formation of abnormal proteinaceous Lewy bodies and Lewy neurites advances in a topographically predictable sequence.
Abstract: The synucleinopathy, idiopathic Parkinson's disease, is a multisystem disorder that involves only a few predisposed nerve cell types in specific regions of the human nervous system. The intracerebral formation of abnormal proteinaceous Lewy bodies and Lewy neurites begins at defined induction sites and advances in a topographically predictable sequence. As the disease progresses, components of the autonomic, limbic, and somatomotor systems become particularly badly damaged. During presymptomatic stages 1-2, inclusion body pathology is confined to the medulla oblongata/pontine tegmentum and olfactory bulb/anterior olfactory nucleus. In stages 3-4, the substantia nigra and other nuclear grays of the midbrain and forebrain become the focus of initially slight and, then, severe pathological changes. At this point, most individuals probably cross the threshold to the symptomatic phase of the illness. In the end-stages 5-6, the process enters the mature neocortex, and the disease manifests itself in all of its clinical dimensions.

TL;DR: All the data strongly support the view that the specific central neurons giving rise to the terminals are monoaminergic, i.e. function by releasing their amines from the synaptic terminals, Consequently, DA, NA and 5-HT seem to be central neurotransmitters.
Abstract: With the help of the highly specific and sensitive fluorescence method of Falck and Hillarp together with the histochemical and pharmacological criteria for the specificity of the fluorescence reaction convincing evidence has been obtained that the fine, varicose nerve fibres observed in a vast number of regions in the mammalian central nervous system (mouse, hamster, rat, guineapig, rabbit, cat), which exhibit a green or yellow fluorescence, contain primary catecholamines and 5-HT respectively. Strong support has been given for the view that CA fibres showing a rapid recovery after administration of α-MMT contain DA, while those showing a slow recovery contain NA. There is little doubt that the monoamine-containing fibres in the brain represent the terminal ramifications of axons belonging to specific monoamine neurons and that they are true synaptic terminals. They seem to make their contacts via the varicosities which have extremely high concentrations of amines and in all probability represent the presynaptic structures, specialized for synthesis, storage and release of the amines. The central monoamine terminals thus have the same characteristic appearance as the adrenergic synaptic terminals in the peripheral nervous system. All the data strongly support the view that the specific central neurons giving rise to the terminals are monoaminergic, i.e. function by releasing their amines from the synaptic terminals. Consequently, DA, NA and 5-HT seem to be central neurotransmitters. Not only the median eminence but also the nuc. caudatus putamen, tuberculum olfactorium, nuc. accumbens and the small circumscribed areas medial to nuc. accumbens contain very fine (partly sublightmicroscopical) CA terminals. These areas react to treatment with reserpine, nialamide-dopa and α-MMT in the same way and since the nuc. caudatus putamen and tuberculum olfactorium are known to have a high DA content it seems likely that abundant DA terminals are accumulated in these special areas.

TL;DR: The observations show that bone-like tissue can be synthesized in vitro by cells cultured from young-adult bone marrow, provided that the medium contains both β-glycerophosphate and, particularly, dexamethasone.
Abstract: Cells from fetal or neonatal skeleton can synthesize bone-like tissue in vitro In contrast, formation of bone-like tissue in vitro by cells derived from adult animals has rarely been reported and has not been achieved using cells from bone marrow We have explored development of bone-like tissue in vitro by bone marrow stromal cells Marrow stromal cells obtained from 40-43-day-old Wistar rats were grown in primary culture for 7 days and then subcultured for 20-30 days Cells were cultured in either alpha-minimal essential medium containing 15% fetal bovine serum, antibiotics, and 50 micrograms/ml ascorbic acid, or the above medium supplemented with either 10 mM Na-beta-glycerophosphate, 10(-8) M dexamethasone, or a combination of both Cultures were examined using phase-contrast microscopy, undemineralized and demineralized tissue histology, histochemistry (for alkaline phosphatase activity), immunohistochemistry (for collagen type, osteonectin, and bone Gla-protein), scanning and transmission electron microscopy, energy dispersive X-ray microanalysis, and X-ray diffraction Collagenous, mineralized nodules exhibiting morphological and ultrastructural characteristics similar to bone were formed in the cultures, but only in the presence of both beta-glycerophosphate and dexamethasone Cells associated with the nodules exhibited alkaline phosphatase activity The matrix of the nodules was composed predominantly of type-I collagen and both osteonectin and Gla-protein were present X-ray microanalysis showed the presence of Ca and P, and X-ray diffraction indicated the mineral to be hydroxyapatite The nodules were also examined for bone morphogenetic protein-like activity Paired diffusion chambers containing partly demineralized nodules and fetal muscle were implanted intraperitonealy in rats Induction of cartilage in relation to muscle was observed histologically after 40 days in the chambers This finding provided further support for the bone-like nature of the nodules The observations show that bone-like tissue can be synthesized in vitro by cells cultured from young-adult bone marrow, provided that the medium contains both beta-glycerophosphate and, particularly, dexamethasone

TL;DR: Perfusion of rat brain followed by immersion fixation with 2.5% glutaraldehyde-1% paraformaldehyde, purification of the first antisera and application of the unlabelled antibody enzyme method were used to specifically identify vasopressin and oxytocin containing cells and fibres.
Abstract: Vasopressin and oxytocin pathways were specifically localized in glutaraldehyde-paraformaldehyde fixed rat brains, with the use of the unlabelled antibody enzyme method and purification of the first antiserum. Vasopressin and oxytocin containing pathways were traced from the paraventricular nucleus towards the dorsal and ventral hippocampus, the nuclei of the amygdala, substantia nigra and substantia grisea, nucleus tractus solitarius, nucleus ambiguus and to the substantia gelatinosa of the spinal cord. In addition, a vasopressin containing pathway between the suprachiasmatic nucleus and the lateral habenular nucleus was demonstrated. The possible nature (axons or dendrites) and role of these extrahypothalamic fibres is discussed in relation to water balance, milk ejection and avoidance behaviour.

TL;DR: An overview is given of the function and ligand-binding properties of integrins as well as of proteins that associate withintegrins and may play a role in their signaling function.
Abstract: Integrins are heterodimeric cell adhesion molecules that link the extracellular matrix to the cytoskeleton. The integrin family in man comprises 24 members, which are the result of different combinations of 1 of 18 alpha- and 1 of 8 beta-subunits. Alternative splicing of mRNA of some alpha- and beta-subunits and postranslational modifications of integrin subunits further increase the diversity of the integrin family. In their capacity as adhesion receptors that organize the cytoskeleton, integrins play an important role in controlling various steps in the signaling pathways that regulate processes as diverse as proliferation, differentiation, apoptosis, and cell migration. The intracellular signals that lead to these effects may be transduced via cytoplasmic components, which have been identified as integrin-binding proteins in yeast two-hybrid screens and which could mediate the coupling of integrins to intracellular signaling pathways. In this review an overview is given of the function and ligand-binding properties of integrins as well as of proteins that associate with integrins and may play a role in their signaling function.
