    Growth of embryonic chick tibiae in ovo and in vitro: A scanning electron microscope study (1979)
    Springer

    Notes: Summary The study describes the ultrastructure of the mineralized portion of chick tibiae from 10 days in ovo to 2 days post-hatch. At 10 days a single mineralized cylinder surrounds the diaphysis. On its outer surface columnar trabeculae join to form ridges parallel to the long axis of the bone. These ridges are covered by another cylinder and form the haversian canals. At 11 days vascular invasion of the marrow cavity occurs and resorption of the endosteal surface begins. This type of periosteal deposition and endosteal resorption is repeated during and subsequent to embryonic development. The mineralized portion of 10-day chick tibiae cultured for 2 days in modified BGJ medium was compared with 10-, 11-, and 12-day tibiae in ovo. Cultured tibiae were similar in length and calcium content to 11-day tibiae in ovo. The form of mineral deposited in ovo and in culture was the same, namely, aggregates of spherical mineral clusters. Differences in culture included the following: (a) few concentric cylinders were deposited as compared with tibiae in ovo; (b) trabeculae were not arranged in rows and ridges in culture; (c) osteocytic lacunae were restricted to bases of trabeculae rather than uniformly distributed as in ovo; and (d) the endosteal surface of tibiae in culture appeared etched.

    Structure and association of wall fibrils produced by regenerating tobacco protoplasts (1979)
    Springer
    Planta 146 (1979), S. 203-210 
    Details
    ISSN: 1432-2048
    Keywords: Cellulose ; Microfibrils ; Negative staining ; Nicotiana ; Protoplasts ; Scanning electron microscopy
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology
    Notes: Abstract A study has been made of the wall fibrils produced by tobacco protoplasts, using scanning electron microscopy in conjunction with negative staining. It has been shown that the fibres seen in scanning electron microscopy correspond to aggregates of microfibrils. These aggregates are only visible where they are lifted clear of the protoplast surface. Negative staining of fixed protoplasts shows that the aggregation of microfibrils into the fibres visible in scanning electron microscopy is probably produced by air-drying. Gentle disruption of microfibrils produces both random broken fragments and bundles of short pieces of fibrillar material about 60 nm in length. This material is present in undisrupted young walls, but not in undisrupted older walls. The microfibrils in young walls seem much more fragile and liable to breakage than those in older walls. These results are discussed in terms of the interpretation of scanning electron microscope images and the mechanism of cellulose microfibril formation by higher plants.

    Classification of human placental villi (1979)
    Springer
    Cell & tissue research 200 (1979), S. 409-423 
    Details
    ISSN: 1432-0878
    Keywords: Human placenta ; Classification of villi ; Histology ; Scanning electron microscopy
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology , Medicine
    Notes: Summary The classification of human placental villi was reviewed on the basis of material prepared by means of special methods. The material from in situ normal-term placentae was biopsied by aspiration into glutaraldehyde. The classification was made on the basis of light-microscopic observations of semithin sections, reconstructions from serial sections, and scanning-electron micrographs. The peripheral villous tree is roughly divided into stem (ramuli), intermediate and terminal villi. The intermediate villi may be further subdivided as mature and immature types, which are found between the stem and terminal villi. Some of the terminal villi possess a local specialization described as the neck region. The histological characteristics and the branching pattern of each type are described, and the basis of the proposed classification is discussed.

    Scanning electron microscopy of peripheral blood leukocytes of the chicken (1979)

    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology , Medicine
    Notes: Summary Polymorphonuclear leukocytes, e.g., neutrophilic granulocytes, were enriched from heparinized blood by a Ficoll-step-gradient centrifugation procedure. Scanning electron microscopy (SEM) revealed a surface morphology of narrow ridge-like profiles and small ruffles with occasional microprocesses. Mononuclear leukocytes were isolated by centrifugation over a Ficoll-Metrizoat gradient. The lymphocytes showed varying numbers of microvilli of different length, size and shape. B lymphocytes, characterized by their capability of “sheep red blood cell (SRBC)-rosette formation”, displayed a similar surface morphology. Completely smooth lymphocytes, described in the literature as T lymphocytes, could not be detected, although many lymphocytes with few microprocesses were observed. Thus, SEM is not a useful tool for distinguishing between B and T lymphocytes in the peripheral blood of chickens. Monocytes were characterized by prominent membrane-like ruffles, but in some cases they closely resembled granulocytes. An influence of the various separation media on the surface morphology of the isolated cells could not be detected when compared with cells isolated by the buffy-coat method.

    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology , Medicine
    Notes: Summary As seen by scanning electron microscopy, the mitochondrial helix in the developing midpiece of mouse testicular spermatozoa is dextral in direction and consists of spherical mitochondrial units arranged in an orderly array of four units per gyre: three appearing in face view and a fourth hidden from view at the back of the gyre. As the spermatozoa mature, the dextral helix is transformed into a sinistral helix. Its constituent spherical mitochondria either change direction abruptly without changing shape; or having first become semilunar or diamond-shaped, they change direction gradually. Mitochondrial division follows the change in helical pitch producing a double sinistral helix. The spherical (or semilunar/diamond-shaped) mitochondria presumably elongate to form the units of the mature midpiece.

    Notes: Summary The three-dimensional ultrastructure of the pineal body of the rat is described on the basis of freeze-fractured preparations. The pineal capsule consists of irregular cells with very flat and perforated processes. Through these openings, extremely branched canaliculi, extending to almost every pineal cell, communicate with the tissue compartment outside the organ. The pericapillary spaces contain, in juxtaposition with capillaries of the fenestrated type, nerve fibers as well as a flocculent granular and filamentous material of unknown origin and chemical nature.

    Scanning electron microscopy of the wall of the third ventricle in the brain of Rana temporaria. Part IV. (1979)

    Topics: Biology , Medicine
    Notes: Summary The surface specializations of the wall of the third cerebral ventricle of Rana temporaria were investigated with the scanning electron microscope. These specializations can be divided into three types: cilia, large bulbous protrusions, and microvillus-like protrusions. Most parts of the ventricular surface are densely ciliated. In contrast, other regions are either scantily ciliated or devoid of cilia. Four areas of the ventricular surface are studded with numerous large bulbous protrusions. These large protrusions can be divided into two types: One type consists of intraventricular end bulbs of dendrites of secretory neurons. The other type is represented by large cytoplasmic extensions of ependymal cells. In the third ventricle of Rana, microvillus-like surface specializations of ependymal cells are ubiquitous structures. Generally, filiform protrusions of varying length are the predominant type. The microvillus-like specializations are transient structures, the number of which varies according to different physiological states of the ependymal cells.

    Notes: Summary Surface features of the ependymal linings of the fourth ventricle in the fowl were analyzed employing the scanning electron microscope (SEM). On the floor of the median sulcus, each ependymal cell has a solitary cilium, whereas on both sides of the sulcus, cilia are so densely distributed that the details of the underlying cell surface are usually obscured. On the roof of the fourth ventricle, except for the surface of the ciliated groove where numerous cilia are present, the ependymal cells are polygonal in shape, and the center of each cell possesses an aggregate of ten to twenty cilia. Cell surfaces of the choroid tela are entirely covered with delicate microvilli and possess clumped cilia. The ependymal cell surfaces of the area postrema are dome-like in shape. Each ependymal cell has a solitary cilium and shows a smooth surface free of microvilli.

    Electron microscopic studies on radular tooth formation in the snails Helix pomatia L. and Limax flavus L. (Pulmonata, Stylommatophora) (1979)

    Keywords: Radula ; Tooth formation ; Pulmonates ; Scanning electron microscopy

    Topics: Biology , Medicine
    Notes: Summary The radular teeth are secreted at the posterior end of the radular gland and move slowly towards the buccal cavity where they start to function. Helix pomatia and Limax flavus were examined to determine whether the newly formed teeth already show their definite species specific shape, or whether they are gradually finished and moulded in the radular gland. Scanning electron micrographs of Helix pomatia show that teeth are secreted in the odontoblast region in their final form. Their surface is still uneven at the outset; the same is true for the newest teeth of Limax flavus. Older teeth ready for use have a smooth surface. This change seems to be brought about by secretory activity of the superior epithelium of the radular sac. Air-dried radulae, previously isolated by KOH maceration, show considerable artefacts at their posterior end. Maceration leads to shrinking of the newest teeth, but does not change their contours. The newly secreted but as yet unhardened teeth become greatly deformed during the drying process.

    Notes: Summary The presence and the three dimensional distribution of the surface connected canalicular system (SCCS) in thrombocytes of a teleost, Cyprinus carpio, were studied using a transmission electron microscope, a high voltage electron microscope and a scanning electron microscope. When the specimens were fixed routinely in glutaraldehyde followed by osmium tetroxide, numerous electron lucent vesicles and canaliculi were distributed throughout the cytoplasm. As ruthenium red-positive reaction product was observed on the inner surface of the vesicles and canaliculi, these are defined as the SCCS of carp thrombocytes. In the stereo-pair of the photographs of thick sectioned specimens and the plastic reconstruction of serially sectioned thrombocytes, we succeeded in finding the whole structure of the SCCS which is composed of numerous anastomosing canaliculi. Scanning electron micrographs revealed many crater-like depressions throughout the cell surface which seem to be the openings of the SCCS.

    Notes: Summary Microcorrosion casts of blood vessels in the skin of the spotted salamander, Salamandra salamandra L., were studied using scanning electron microscopy. The investigated vessels include a subepidermal network of respiratory capillaries and the vessels of poison glands. A hypothesis is proposed, according to which both types of vascular beds possess a common origin. Probable factors involved in the differentiation of the primary netword of the subepidermal vessels in larvae are indicated and speculation concerning the supposed mosaic type of circulation in the capillaries of the subepidermal respiratory bed is presented.

    Three dimensional organization of mammalian adrenal cortex (1979)

    Topics: Biology , Medicine
    Notes: Summary The adrenal cortex of different mammals was studied by SEM in order to demonstrate its actual three-dimensional organization. In the rat, as well as in the cat and pig, the adrenal cortex appeared as a “tunnelled continuum” of polyhedral cells arranged in plate-like structures (laminae). This laminar arrangement was more evident in the inner fasciculate and reticular zones where the cortex revealed a striking similarity to liver tissue. The polyhedral cells of all cortical zones possessed regular facets populated by small pits, larger invaginations and numerous microvilli with the exception of very short and smooth areas probably corresponding to attachment zones and/or gap junctions. This cellular architecture produced a labyrinthic system of intercellular channels or lacunae in which the capillaries were suspended. The pericapillary areas of this labyrinth contained microvilli, amorphous material, a delicate net of fibrils and occasional cells. The intercellular compartment of this lacunar system was mainly bordered by numerous microvilli arising from endocrine cells. The luminal surface of the capillary wall showed not only irregularly protruding margins (interpretable as endothelial junctions) but also clearly overlapping and flattened endothelial extensions. In all the animals and areas of the adrenal cortex examined, the endothelial wall was provided with abundant clusters of small fenestrations (about 50 nm in diameter) generally arranged in sieve plates. Larger fenestrations were noted mainly in the fasciculate and reticular zones of the cat and pig and occasionally in the rat. A final point related to the nature and significance of sinusoidal fenestrations was the occurrence of irregularly shaped and intracapillary located cells mainly noted in the deeper zones of the fasciculate and reticular zones of the gland. These elements — possessing the surface characteristics of macrophages — were observed, with their irregular and slender evaginations, in close proximity to the large fenestrations in a manner reminiscent of Kupffer cells within the lumen of liver sinusoids.

    Notes: Summary The ventricular surface of the paraventricular organ in the domestic fowl is covered with supraependymal fiber elements. These fibers form a dense network having a web-like appearance and a coarse network of fibers running over the ventricular surface. The dense, web-like networks are mainly distributed throughout the caudal region of this organ, whereas the coarse networks are observed in the rostral region. In addition to these structures, spherical bodies with diameters approximately 2.5 to 6 μm are also encountered.

    Metabolism of theophylline to caffeine in human fetal liver (1979)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1979-12-14
    Description: Caffeine (1,3,7-trimethylxanthine) is a biotransformation product of theophylline (1,3-dimethylxanthine) in the human fetus. Liver explants, obtained from human fetuses with gestational ages of 12 to 20 weeks, were incubated with theophylline and produced caffeine and, in lesser amounts, 1,3-dimethyluric acid and 3-methylxanthine. These findings suggest that the predominant pathway in theophylline metabolism in the fetus and newborn infant is the methylation reaction producing caffeine. This may contribute to the neonate's exceedingly slower elimination of caffeine relative to theophylline. Caffeine produced from theophylline may add to the pharmacologic effects of theophylline in newborn infants with apnea.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Aranda, J V -- Louridas, A T -- Vitullo, B B -- Thom, P -- Aldridge, A -- Haber, R -- New York, N.Y. -- Science. 1979 Dec 14;206(4424):1319-21.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/515734" target="_blank"〉PubMed〈/a〉

    Regional localization of the gene for human phosphoribosylpyrophosphate synthetase on the X chromosome (1979)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1979-03-09
    Description: Sixty-eight independent hybrid clones were isolated after irradiated normal human lymphocytes were fused with Chinese hamster fibroblasts lacking hypoxanthine-guanine phosphoribosyltransferase activity. The cells were grown under selective conditions requiring retention of the X chromosome-linked locus for human hypoxanthine-guanine phosphoribosyltransferase. The frequency and patterns of cotransference of human phosphoribosylpyrophosphate synthetase with the selected marker and with additional X-linked enzymatic markers confirm X linkage of the structural gene for human phosphoribosylpyrophosphate synthetase and support assignment of this gene to a position on the long arm of the X, between the loci for alpha-galactosidase and hypoxanthine-guanine phosphoribosyltransferase.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Becker, M A -- Yen, R C -- Itkin, P -- Goss, S J -- Seegmiller, J E -- Bakay, B -- New York, N.Y. -- Science. 1979 Mar 9;203(4384):1016-9.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/218284" target="_blank"〉PubMed〈/a〉

    Pituitary-brain vascular relations: a new paradigm (1979)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1979-04-06
    Description: Vascular casts of the pituitary gland have demonstrated a paucity of veins extending from the adenohypophysis to the systemic circulation and have suggested that some adenohypophyseal venous blood returns to the neurohypophysis. The neurohypophyseal capillary bed may function as a vascular switch and in this article a series of 14 questions are proposed regarding the vascular dynamics of the pituitary. Together these questions raise the larger question, namely, whether pituitary hormones are transported directly to the brain to modify brain function?〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Bergland, R M -- Page, R B -- New York, N.Y. -- Science. 1979 Apr 6;204(4388):18-24.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/373118" target="_blank"〉PubMed〈/a〉

    Comparative biochemistry and drug design for infectious disease (1979)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1979-09-07
    Description: In the past two decades, biochemistry and molecular biology have demonstrated the existence of potentially exploitable biochemical differences between etiologic agents of disease and their hosts. Known differences between organism and host with respect to metabolism and polymer structure point to the detailed characterization of key proteins as the focus for the development of potential inhibitors. In the last decade, the methodology of the isolation, characterization, and inactivation of proteins and enzymes has been advanced. The present scientific and technological base suggests that new efforts toward the development of selective chemotherapeutic agents for infections caused by bacteria, viruses, protozoa, and higher eukaryotes should exploit the known differences in proteins or other specific biopolymers serving crucial structural or metabolic roles in the economy of the parasite.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Cohen, S S -- New York, N.Y. -- Science. 1979 Sep 7;205(4410):964-71.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/382357" target="_blank"〉PubMed〈/a〉

    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1979-07-27
    Description: The transmission of the Z deficient allele of alpha 1-antitrypsin was studied in 23 families, each with a single parent heterozygous for this allele. When the mother carried the Z allele, the distribution of phenotypes in the children did not differ significantly from the expected frequency. In contrast, when the father was the carrier, a significant increase of heterozygous phenotypes was observed in the children. This observation suggests that a selective advantage is associated with the expression of the Z allele in male gametes.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Chapuis-Cellier, C -- Arnaud, P -- New York, N.Y. -- Science. 1979 Jul 27;205(4404):407-8.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/313077" target="_blank"〉PubMed〈/a〉

    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1979-11-09
    Description: A flickering light presented to the eye produces a small alternating voltage at the scalp of a subject. This alternating voltage indicates the following response of the brain to the flicker. If every other flash in the flicker is displaced temporally by as little as 30 microseconds, an asymmetry appears in the brain's alternating voltage. The results suggest an underlying mechanism that may enhance visual detection of high-frequency flicker.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Diamond, A L -- New York, N.Y. -- Science. 1979 Nov 9;206(4419):708-10.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/493977" target="_blank"〉PubMed〈/a〉

    Description: Human erythrocytes have been freeze-fractured, and the polypeptides associated with the separate halves of the membrane bilayer have been analyzed by sodium dodecyl sulfate polyacrylamide gel electrophoresis. The transmembrane proteins were differentially separated by the fracture process. Although sialoglycoproteins associated with the outer half of the membrane, the anion transport protein (band 3) mainly remained with the inner half of the membrane. Well-defined fragments of the sialoglycoproteins were produced by the freeze-fracture procedure, indicating that selected covalent bonds of these transmembrane proteins were broken.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Edwards, H H -- Mueller, T J -- Morrison, M -- New York, N.Y. -- Science. 1979 Mar 30;203(4387):1343-6.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/424755" target="_blank"〉PubMed〈/a〉

    Description: It has been suggested that the inverted hand position of left-handers during writing indicates the left hemisphere of their brain is linguistically specialized and that the writing of these left-handers may be controlled via ipsilateral pathways. Electroencephalograph alpha asymmetry measures at central and parietal leads, as well as dichotic tests, differentiated right-handers from left-handers, but not inverters from noninverters. Electroencephalograph differences between hand posture groups did appear, but only at occipital leads during reading and writing tasks. Regardless of hand posture or speech lateralization, the right central region of the brain is significantly involved in the control of left-handed writing.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Herron, J -- Galin, D -- Johnstone, J -- Ornstein, R E -- New York, N.Y. -- Science. 1979 Sep 21;205(4412):1285-9.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/472745" target="_blank"〉PubMed〈/a〉

    Shifts in perception of size after adaptation to gratings (1979)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1979-12-14
    Description: After viewing a suitable grating of vertical stripes for 5 minutes, subjects overestimated the width of a rectangle by 6 percent. The shifts in perception of size occurred whether individual stripes in the grating were narrower than, equal to, or wider than the rectangle. Rectangle width was underestimated only if the grating stripes were extremely wide, with a spatial frequency lower than most of the effective amplitude spectrum of the rectangle. These findings (and complementary ones with horizontal gratings) suggest that the visual system codes size on the basis of spatial frequency components, rather than directly in terms of width.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Frome, F S -- Levinson, J Z -- Danielson, J T -- Clavadetscher, J E -- New York, N.Y. -- Science. 1979 Dec 14;206(4424):1327-9.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/515736" target="_blank"〉PubMed〈/a〉

    Description: In experiments designed to measure human cell survival sith +/- 2 percent accuracy it was found that low doses (21 to 87 rad) of gamma-rays inactivated the colony-forming ability of cultured human cells with a probability of 0.00226 +/- 0.00012 per rad.

    Cigarette smoking induces functional antiprotease deficiency in the lower respiratory tract of humans (1979)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1979-12-14
    Description: Current concepts of the pathogenesis of emphysema suggest that it results from an imbalance of elastase and antielastase activity within the alveolar structures. Although emphysema that is associated with hereditary deficiency of serum alpha 1-antitrypsin conforms to this scheme, the major risk factor in the more common form of emphysema is cigarette smoking. A study was designed to evaluate the premise that cigarette smoking may be associated with an acquired, functional defect in lung alpha 1-antitrypsin. Determination of the antielastase activity of alpha 1-antitrypsin obtained from the lungs of smoking and nonsmoking individuals revealed a nearly twofold reduction in the functional activity of this elastase inhibitor in the lungs of cigarette smokers. These data suggest that cigarette smokers may lose some of the normal antielastase protective screen of the lower respiratory tract, making them more vulnerable to destructive lung disease.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Gadek, J E -- Fells, G A -- Crystal, R G -- New York, N.Y. -- Science. 1979 Dec 14;206(4424):1315-6.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/316188" target="_blank"〉PubMed〈/a〉

    Lithium: a modulator of cyclic AMP-dependent events in lymphocytes? (1979)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1979-01-26
    Description: Theophylline, salbutamol, isoproterenol, and dibutyryl cyclic AMP inhibited E-rosette formation by human T lymphocytes and immunoglobulin M secretion from human plaque-forming B cells and augmented T-suppressor cell activity in three patients with agammaglobulinemia. Lithium chloride increased mitogen-induced lymphocyte proliferation and inhibited suppressor cell activity. In the presence of lithium, the effects of all the drugs except dibutyryl cyclic AMP could be prevented. The data suggest a role for lithium in the modulation of cyclic AMP-dependent events in lymphocytes. Its potential role as an inhibitor of suppressor cell activity warrants further attention.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Gelfand, E W -- Dosch, H M -- Hastings, B -- Shore, A -- New York, N.Y. -- Science. 1979 Jan 26;203(4378):365-7.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/216075" target="_blank"〉PubMed〈/a〉

    Automatic classification of electroencephalograms: Kullback-Leibler nearest neighbor rules (1979)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1979-07-13
    Description: A prototypic problem in screening of electroencephalograms in the automatic classification of stationary electroencephalogram time series is treated here by the Kullback-Leibler nearest neighbor rule approach. In that problem, the category or state of an individual is classified by comparison of his or her electroencephalogram with those taken from other individuals in the alternative categories. The Kullback-Leibler nearest neighbor classification rules yield a statistically reliable estimate of the smallest possible probability of electroencephalogram misclassification with a relatively small number of labeled sample electroencephalograms. The automatic classification of anesthesia levels L1 and L3, respectively the anesthesia levels insufficient and sufficient for deep surgery, is treated by machine computation on the electroencephalogram alone.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Gersch, W -- Martinelli, F -- Yonemoto, J -- Low, M D -- Mc Ewan, J A -- New York, N.Y. -- Science. 1979 Jul 13;205(4402):193-5.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/451587" target="_blank"〉PubMed〈/a〉

    Electroencephalogram correlates of higher cortical functions (1979)

    Details
    Publication Date: 1979-02-16
    Description: By means of two-stage, nonlinear multivariate pattern recognition, electroencephalograms (EEG's) were analyzed during performance of verbal and spatial tasks. Complex scalp distributions of theta-, beta-, and, to a lesser extent, alpha-band spectral intensities discriminated between the two members of a pair of tasks, such as writing sentences and Koh's block design. Small EEG asymmetries were probably attributable to limb movements and other uncontrolled noncognitive aspects of tasks. Significant EEG differences beteeen cognitive tasks were eliminated when controls for inter-task differences in efferent activity, stimulus characteristics, and performance-related factors were introduced. Each controlled task was associated with an approximately 10 percent reduction, as compared with visual fixation, in the magnitude of alpha- and beta-band spectral intensity. This effect occurred bilaterally and was approximately the same over occipital, parietal, and central regions, with some minor difference over the frontal region in the beta band. With these controls, no evidence for lateralization of different cognitive functions was found in the EEG.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Gevins, A S -- Zeitlin, G M -- Doyle, J C -- Yingling, C D -- Schaffer, R E -- Callaway, E -- Yeager, C L -- New York, N.Y. -- Science. 1979 Feb 16;203(4381):665-8.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/760212" target="_blank"〉PubMed〈/a〉

The assay detects insulin binding sites at concentrations as low as 0.1 nanomolar; distinguishes between receptors originating from human placental membranes, human lymphoblastoid cells, and mouse liver membranes; and measures the receptor independently of its binding function. Down-regulation, or loss of binding after exposure to insulin, is associated with loss of immunoreactive receptor.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Harrison, L C -- Flier, J -- Itin, A -- Kahn, C R -- Roth, J -- New York, N.Y. -- Science. 1979 Feb 9;203(4380):544-7.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/83675" target="_blank"〉PubMed〈/a〉

    Defects of bile acid synthesis in Zellweger's syndrome (1979)

    Details
    Publication Date: 1979-03-16
    Description: Abnormal mitochondrial structure and function have been documented in patients with Zellweger's syndrome (cerebrohepatorenal syndrome). In vitro studies have suggested that the formation of C24 bile acids (chenodeoxycholic acid and cholic acid) from C27 cholesterol requires mitochondrial oxidative clevage of the terminal three carbons of the side chain. Therefore, three patients with Zellweger's syndrome were examined for the presence of mitochondrial defects in bile acid synthesis. All three excreted excessive amounts of 3 alpha, 7 alpha-dihydroxy-5 beta-cholestan-26-oicacid, 3 alpha, 7 alpha, 12 alpha-trihydroxy-5 beta-cholestan-26-oic acid, and 3 alpha, 7 alpha, 12 alpha, 24 xi-tetrahydroxy-5 beta-cholestan-26-oic acid (varanic acid), precursors of chenodeoxycholic acid and cholic acid that have undergone only partial side chain oxidation. These findings give added support to the role of mitochondrial oxidative side chain cleavage in the overall scheme of bile acid synthesis.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Hanson, R F -- Szczepanik-VanLeeuwen, P -- Williams, G C -- Grabowski, G -- Sharp, H L -- New York, N.Y. -- Science. 1979 Mar 16;203(4385):1107-8.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/424737" target="_blank"〉PubMed〈/a〉

    Specific nonopiate receptors for beta-endorphin (1979)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1979-09-07
    Description: Iodinated beta H-[2-D-alanine]endorphin exhibits specific binding to cultured human lymphocytes. The binding is inhibited by low concentrations of beta-endorphin and its D-alanine derivative, but is not affected by opiate agonists and antagonists, or by enkephalin analogs, beta-lipotropin, adrenocorticotrophic hormone, or alpha-melanocyte-stimulating hormone; this suggests the existence of a specific, non-opiate binding site (receptor) for beta-endorphin. The carboxy-terminal region of beta-endorphin is essential for this binding activity, since alpha-endorphin is not active. beta-Endorphin may be a circulating hormone with peripheral physiological effects that are not primarily mediated through interactions with opiate or enkephalin receptors.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Hazum, E -- Chang, K J -- Cuatrecasas, P -- New York, N.Y. -- Science. 1979 Sep 7;205(4410):1033-5.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/224457" target="_blank"〉PubMed〈/a〉

    Stimulation of human periaqueductal gray for pain relief increases immunoreactive beta-endorphin in ventricular fluid (1979)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1979-01-19
    Description: Immunoreactive beta-endorphin was measured in the ventricular fluid of six patients with chronic pain. Stimulation of the periaqueductal gray matter in three patients with pain of peripheral origin resulted in significant increases (50 to 300 percent) in the concentration of ventricular immunoreactive beta-endorphin. In three other patients suffering deafferentation dysesthesia, stimulation of the posterior limb of the internal capsule did not alter the concentration of this peptide. These results provide evidence of the release of human immunoreactive beta-endorphin in vivo and suggest that naloxone-reversible pain relief achieved by stimulation of the periaqueductal gray matter may be in part mediated by the activation of beta-endorphin-rich diencephalic areas.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Hosobuchi, Y -- Rossier, J -- Bloom, F E -- Guillemin, R -- New York, N.Y. -- Science. 1979 Jan 19;203(4377):279-81.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/83674" target="_blank"〉PubMed〈/a〉

    Risk with energy from conventional and nonconventional sources (1979)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1979-02-23
    Description: Risk to human health was compared for five conventional and six nonconventional energy systems. The entire cycle for producing energy was considered, not just part. The most important conclusion drawn is that the risk to human health from nonconventional sources can be as high as, or even higher than, that of conventional sources. This result is produced only when the risk per unit energy is considered, rather than the risk per solar panel or windmill. The risk from nonconventional energy sources derives from the large amount of material and labor needed, along with their backup and storage requirements. Risk evaluation is a relatively new discipline, and therefore the results presented here can be considered only a beginning. However, society should keep relative risk in mind when evaluating present and future energy sources.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Inhaber, H -- New York, N.Y. -- Science. 1979 Feb 23;203(4382):718-23.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/419404" target="_blank"〉PubMed〈/a〉

    Publication Date: 1979-03-09
    Description: Movement time varies as a function of amplitude and requirements for precision, according to Fitts' law, but when subjects perform two-handed movements to targets of widely disparate difficulty they do so simultaneously. The hand moving to an "easy" target moves more slowly to accommodate its "difficult" counterpart, yet both hands reach peak velocity and acceleration synchronously. This result suggests that the brain produces simultaneity of action not by controlling each limb independently, but by organizing functional groupings of muscles that are constrained to act as a single unit.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kelso, J A -- Southard, D L -- Goodman, D -- New York, N.Y. -- Science. 1979 Mar 9;203(4384):1029-31.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/424729" target="_blank"〉PubMed〈/a〉

    A correlation between platelet monoamine oxidase activity and plasma prolactin concentrations in man (1979)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1979-10-26
    Description: Increases in plasma prolactin concentrations produced by alpha-methyl-p-tyrosine, a catecholamine synthesis inhibitor, varied inversely with baseline platelet monoamine oxidase activity in 12 patients with chronic schizophrenia. In normal volunteers with low monoamine oxidase activity and in unmedicated patients with chronic schizophrenia, plasma prolactin concentrations varied directly with platelet monoamine oxidase activity. No such relationship was found in normal subjects with high platelet monoamine oxidase activity. These data suggest that platelet monoamine oxidase activity reflects monoaminergic activity in the tubero-infundibular system, which in turn affects plasma prolactin concentrations. This relationship may be important in patients with low platelet monoamine oxidase activity, such as some chronic schizophrenics.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kleinman, J E -- Potkin, S -- Rogol, A -- Buchsbaum, M S -- Murphy, D L -- Gillin, J C -- Nasrallah, H A -- Wyatt, R J -- New York, N.Y. -- Science. 1979 Oct 26;206(4417):479-81.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/504993" target="_blank"〉PubMed〈/a〉

    3-Methoxy-4-hydroxyphenethyleneglycol production by human brain in vivo (1979)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1979-09-07
    Description: A direct method has been employed to estimate the rate of production by human brain of 3-methoxy-4-hydroxyphenethyleneglycol, the major metabolite of brain norepinephrine, a brain neurotransmitter. Venous specimens were obtained from the internal jugular vein from ten awake human subjects at a puncture site above the common facial vein, the first major source of extracranial inflow. Arterial specimens were simultaneously obtained from the radial artery. Plasma samples were assayed and a highly significant difference was found in the concentration of the metabolite in plasma coming out of the brain (venous blood) as compared to plasma entering the brain (arterial blood). This venous-arterial difference was calculated to be 0.7 +/- 0.1 nanogram per milliliter of blood. Assuming an adult brain weight of 1400 grams and normal cerebral blood flow, it is estimated that the rate of production of 3-methoxy-4-hydroxyphenethyleneglycol by the awake human brain is approximately 597 nanograms per minute or 35.8 micrograms per hour. Urine specimens were also collected from six of these subjects during a period of 1 to 3.5 hours, which bracketed the time the blood samples were obtained. For these six subjects the output of 3-methyoxy-4-hydroxyphenethyleneglycol by whole brain was estimated to be 40.9 micrograms per hour, whereas the rate of its excretion into urine was 64.5 micrograms per hour.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Maas, J W -- Hattox, S E -- Greene, N M -- Landis, D H -- New York, N.Y. -- Science. 1979 Sep 7;205(4410):1025-7.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/472724" target="_blank"〉PubMed〈/a〉

    Description: Binding sites for tritum-labeled gamma-aminobutyric acid (GABA) in cerebellar cortex of Huntington's chorea patients have an increased affinity but unaltered maximum capacity as compared to binding sites in tissue from control patients. A similar binding pattern is produced in control membranes by treatment with Triton X-100, phospholipase C, or glycerophosphoethanolamine. Thus, it is likely that phospholipids or their metabolites regulate the accessibility of the GABA binding site and that this regulation is abnormal in Huntington's chorea.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lloyd, K G -- Davidson, L -- New York, N.Y. -- Science. 1979 Sep 14;205(4411):1147-9.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/224459" target="_blank"〉PubMed〈/a〉

    Description: In each of six family members who were heterozygous at the X-linked locus for glucose-6-phosphate dehydrogenase, only one or the other of the two alleles at that locus was almost exclusively expressed. The data are consistent with evidence that X-chromosome inactivation is a random process that may be followed by selection for one of the two resulting cell types on the basis of an unknown gene, which is located on the X chromosome and which can affect the rate of proliferation of hemopoietic cells in humans.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Luzzatto, L -- Usanga, E A -- Bienzle, U -- Esan, G F -- Fusuan, F A -- New York, N.Y. -- Science. 1979 Sep 28;205(4413):1418-20.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/472761" target="_blank"〉PubMed〈/a〉

During multiple-dose administration of pergolide, plasma prolactin concentrations remain markedly reduced (greater than 80 percnet) and gradually return to control levels several days after drug administration is discontinued.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lemberger, L -- Crabtree, R E -- New York, N.Y. -- Science. 1979 Sep 14;205(4411):1151-3.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/382359" target="_blank"〉PubMed〈/a〉

    Differences in neural organization between individuals with inverted and noninverted handwriting postures (1979)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1979-08-17
    Description: Levy's hypothesis that movements of the distal musculature are controlled by ipsilateral motor projections in subjects with inverted writing posture was tested in a reaction-time experiment with lateralized auditory, tactual, and visual stimulation. Subjects were required to depress a response key with the left or right index finger when they detected a stimulus in either the left or right sensory field. Writers with noninverted posture responded quickest to stimuli on the same side as the responding hand in all modalities tested, whereas inverted writers showed this pattern only in auditory and tactual modalities. In the visual modality, they responded quickest to stimuli on the side opposite the responding hand. Because Levy's hypothesis predicts the latter effect in all modalities for inverted writers, it is challenged by our results, which suggest that inverted writers may be characterized by anomalous visual or visuomotor organization.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Moscovitch, M -- Smith, L C -- New York, N.Y. -- Science. 1979 Aug 17;205(4407):710-3.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/462180" target="_blank"〉PubMed〈/a〉

    Insulin receptor binding in obesity: a reassessment (1979)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1979-09-07
    Description: A defect in the binding of insulin to circulating monocytes occurs when obese patients are hospitalized and fed a liberal carbohydrate diet. Under ordinary circumstances, most obese patients have normal insulin binding despite very high concentrations of serum insulin. These results show that insulin does not necessarily regulate its own receptor in vivo--as it does in vitro.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Misbin, R I -- O'Leary, J P -- Pulkkinen, A -- New York, N.Y. -- Science. 1979 Sep 7;205(4410):1003-4.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/472718" target="_blank"〉PubMed〈/a〉

    Platelet aggregation induced by ultrasound under specialized conditions in vitro (1979)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1979-08-03
    Description: Human platelets were induced by 2.1-megahertz ultrasound to form aggregates around gas-filled pores in membranes immersed in platelet-rich plasma. The spatial peak intensities required were only about 16 to 32 milliwatts per square centimeter. Ultrasound generated by a medical Doppler device, whose intensity exceeded this, induced aggregate formation under the same conditions.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Miller, D L -- Nyborg, W L -- Whitcomb, C C -- New York, N.Y. -- Science. 1979 Aug 3;205(4405):505-7.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/451616" target="_blank"〉PubMed〈/a〉
