[cortical projections from the reuniens nucleus of the thalamus in the rat]. | direct projections from the reuniens nucleus to the cerebral cortex were examined using the anterograde tracing method of phaseolus vulgaris leucoagglutinin (pha-l) in the rat. the reuniens nucleus was found to project to widespread cortical regions. the labeled fibers from the reuniens nucleus terminated in layers i, iii and iv of the frontal cortex including the medial and ventrolateral orbital cortices, the cingulate cortex, and the infralimbic cortex. a few fibers from the nucleus reuniens a ... | 1994 | 8091944 |
human-specific c-neu proto-oncogene protein overexpression in human malignant astrocytomas before and after xenografting. | overexpression of human-specific c-neu proto-oncogene transmembrane tyrosine kinase receptor protein (p185) is an index of cell transformation and of poor patient survival in several malignancies. the authors studied this protein in low- and high-grade human malignant astrocytomas before and after xenografting into aspiration pockets in rat cortex. human-specific p185c-neu-positive cells were found in tumor specimens from all grades of astrocytoma. significantly fewer p185c-neu-positive cells we ... | 1993 | 8093625 |
localization of tyrosine hydroxylase in neuronal targets and efferents of the area postrema in the nucleus tractus solitarii of the rat. | catecholamines in the nucleus tractus solitarii (nts) have been implicated in autonomic responses to circulating hormones that act on neurons in the area postrema, the most caudal circumventricular organ in brain. we combined immunoperoxidase labeling of the anterograde tracer, phaseolus vulgaris leucoagglutinin (phal) with immunogold-silver labeling of tyrosine hydroxylase to determine whether this enzymatic marker for catecholamines was present in efferents from the area postrema or their targ ... | 1993 | 8096227 |
luteinizing hormone-releasing hormone and gamma-aminobutyric acid neurons in the medial preoptic area are synaptic targets of dopamine axons originating in anterior periventricular areas. | the aim of this study was to characterize further the transmitter content and the location of the parent cells of tyrosine hydroxylase-immunoreactive boutons terminating on luteinizing hormone-releasing hormone- and glutamic acid decarboxylase-immunoreactive neurons in the rat medial preoptic area. electron microscopic immunostaining for luteinizing hormone-releasing hormone, tyrosine hydroxylase or glutamic acid decarboxylase was performed on desipramine-pretreated (to protect norepinephrine an ... | 1993 | 8097941 |
how is leghemoglobin involved in peribacteroid membrane degradation during nodule senescence? | an increase in the rate of succinate and glutamate uptake by isolated symbiosomes from french bean nodules was observed in the presence of iron plus h2o2. the lipid bilayer, and not proteins involved in transport, seems to be the major target of radical attack. leghemoglobin in the presence of a 6-fold excess of h2o2 (where heme breakdown and iron release occurred) provoked also an increase in peribacteroid membrane permeability. in contrast, this hemoprotein in the presence of a 2-fold excess o ... | 1993 | 8100785 |
the sites of origin of dopaminergic afferent fibers to the lateral habenular nucleus in the rat. | the lateral habenular nucleus of the rat contains a dense plexus of dopaminergic fibers, which are more marked in the medial part of the lateral habenular nucleus than in its lateral counterpart. employing a combination of fluorescent retrograde axonal tracing with fluorogold and tyrosine hydroxylase immunofluorescence histochemistry, we investigated the distribution of cells of origin of the dopaminergic afferent fibers to the lateral habenular nucleus in the rat. the cells double-labeled with ... | 1993 | 8101849 |
spinal cord and trigeminal projections to the pontine parabrachial region in the rat as demonstrated with phaseolus vulgaris leucoagglutinin. | in order to determine the regions within the parabrachial nucleus that receive synaptic input from nociceptive regions of the spinal cord and medulla in the rat, we analyzed the "golgi-like" labeling produced by anterograde transport of phaseolus vulgaris leucoagglutinin (pha-l) from discrete iontophoretic injections confined to either the superficial dorsal horn of the lumbar spinal cord or to the superficial dorsal horn of the trigeminal nucleus at the level of the obex. labeled fibers from bo ... | 1994 | 8106661 |
patterns of sialylation in differentiating rat decidual cells as revealed by lectin histochemistry. | lectin histochemistry was used to demonstrate changes in the surface glycan distribution of uterine stromal cells as they differentiate to form decidual cells. decidualization was induced in hormone-treated, ovariectomized rat uteri by needle scratch. uterine tissue from days 2 to 8 of deciduoma development was examined with a panel of lectins specific for terminal non-reducing structures in n- and o-linked classes of glycoprotein glycan, including alpha 2,3- and alpha 2,6-linked sialic acid res ... | 1993 | 8107049 |
a mutation in the indole-3-acetic acid biosynthesis pathway of pseudomonas syringae pv. syringae affects growth in phaseolus vulgaris and syringomycin production. | homologs of the genes for indole-3-acetic acid (iaa) biosynthesis from pseudomonas syringae pv. savastanoi were retrieved from a genomic library of p. syringae pv. syringae, and their nucleotide sequences were determined. sequence relatedness between the p. syringae pv. syringae and p. syringae pv. savastanoi iaa operons is greater than 90% within the iaam and iaah loci but declines dramatically at a position approximately 200 bp 5' of the iaam translation initiation codon. a third open reading ... | 1994 | 8113177 |
characterization of a soybean beta-conglycinin-degrading protease cleavage site. | protease c1, an enzyme from soybean (glycine max [l.] merrill cv amsoy 71) seedling cotyledons, was previously determined to be the enzyme responsible for the initial degradation of the alpha' and alpha subunits, but not the beta subunit, of beta-conglycinin storage protein. the sizes of the proteolytic products generated by the action of protease c1 suggest that the cleavage sites on the alpha' and alpha subunits of beta-conglycinin may be located in their n-terminal domain, which is not found ... | 1994 | 8115542 |
migration of human malignant astrocytoma cells in the mammalian brain: scherer revisited. | fresh suspensions of human glioblastoma multiforme were preincubated in the plant lectin phaseolus vulgaris leucoagglutinin (phal) and implanted into cortical pockets in adult rat brain. brains were investigated periodically over 30 postoperative days and the migration of the human glioblastoma cells was traced with anti-phal immunofluorescence or the overexpression of human specific p185c-neu a specific marker of a class of human malignant astrocytoma cells. the principal pathway of migration o ... | 1993 | 8116480 |
food properties affecting the digestion and absorption of carbohydrates. | carbohydrate foods differ considerably in their effects on postprandial glucose and insulin responses. qualitative differences among starchy foods are particularly intriguing because of the dominance of starch in human diets. this paper focuses on food properties in cereal (eg, pasta, bread, arepas, and porridge) and legume products (eg, red kidney beans and lentils) that affect metabolic responses to starch. studies in healthy subjects have found that postprandial blood glucose and insulin resp ... | 1994 | 8116553 |
[nutrition disorders in fattening pigs in an "organic" facility]. | in a herd of fattening pigs under an organic system of management, the following problems were observed: sudden deaths, skin diseases, diarrhea, increased restlessness and cannibalism. the diet consisted of cereals (barley, wheat, rye), field beans, lime stone and deteriorated, raw potatoes without addition of a mineral mixture. deficiencies of sodium, zinc and selenium were found in the diet and in the animals (blood samples, autopsy). the vitamin e status in the pigs was also below normal. | 1993 | 8122238 |
anterograde and retrograde tracing of projections from the ventral tegmental area to the hippocampal formation in the rat. | employing anterograde tracing with phaseolus vulgaris-leucoagglutinin (pha-l), and a triple labeling protocol using retrogradely transported fluorescent tracers, we examined the projections from the ventral tegmental area (vta-a10) to the hippocampal formation (hf) in the rat. injections of pha-l into vta resulted in labeling in the ventral subiculum (stratum oriens and molecular layer) and in the adjacent ca1 field (stratum oriens, pyramidal, suprapyramidal and molecular layers) of hf. addition ... | 1994 | 8124582 |
mutation of asn128 to asp of phaseolus vulgaris leucoagglutinin (pha-l) eliminates carbohydrate-binding and biological activity. | phytohaemagglutinin (pha) is the major lectin present in the seeds of the common bean, phaseolus vulgaris, and pha-l is the leucocyte-agglutinating form of this lectin. this tetrameric glycoprotein accumulates in the vacuoles of storage parenchyma cells. based on amino acid sequence comparisons of legume lectins and the three-dimensional structure of lectin-carbohydrate complexes, asn128 can be identified as a likely candidate for site-directed mutagenesis to create a mutant pha-l that does not ... | 1993 | 8130390 |
embryonic purkinje cells grafted on the surface of the adult uninjured rat cerebellum migrate in the host parenchyma and induce sprouting of intact climbing fibres. | by grafting solid pieces of cerebellar anlage onto the surface of the adult rat cerebellum, we have investigated the problem of the interactions between embryonic and adult neurons in an intact brain. a few days after grafting, embryonic astrocytic processes crossed the graft--host interface and radiated into the recipient molecular layer. several grafted purkinje cells also migrated into the host brain along such processes as well as adult bergmann glia. adult climbing fibres, labelled by means ... | 1994 | 8130928 |
expression of beta 1-6-branched n-linked oligosaccharides is associated with activation in human t4 and t8 cell populations. | activation of human t lymphocytes by phorbol 12-myristate 13-acetate and leukoagglutinin from phaseolus vulgaris (l-pha) results in important changes in n-glycosylation. the most important event is the increase, in both t4 and t8 cells (especially the latter), of l-pha+ structures characterized by beta 1-6-branching of complex-type oligosaccharides. moreover, the existence of a cd4-mediated increase of these beta 1-6-branched structures on positively selected t4 cells, as compared with the negat ... | 1994 | 8132531 |
