    Notes: Neutron diffraction measurements were made on artificial superlattices of CoO-NiO, (CoO)m(NiO)n×l prepared on the (0001) surface of α-Al2O3. (111) layers of CoO and NiO, each less than 2 nm thick (2≤m,n≤8), were stacked alternatively to a total thickness of less than 70 nm (m+n≤15,l≤25). A well-defined magnetic Bragg peak indexed as (1/2 1/2 1/2) was observed for all the samples, and a magnetic structure of type FCC2 with the spin axis lying in the (111) planes grown was suggested. The temperature dependence of the magnetic peak intensity revealed a sharp, single magnetic transition. The Néel temperature was found to vary as a linear function of n/(m+n).

    PHYSIOLOGICAL BASIS OF VISUAL ACUITY AND ITS DEVELOPMENT IN KITTENS (1979)

    Notes: Summary To answer the questions, (1) Which cells in the visual system are responsible for high visual acuity and (2) Does the function of the cells which provide high visual acuity develop postnatally; single cell studies have been made in the retina, lateral geniculate nucleus (LGN) and visual cortex of cats of different ages. Sustained-X retinal ganglion cells in the area centralis (the equivalent retinal position to the human fovea) set the upper limit of visual acuity. The cellular acuity develops postnatally until it reaches the adult level at 3–4 months-of-age. The improvement of acuity is associated with an increase in the strength of the inhibitory surround mechanism of the receptive field of sustained cells in the area centralis. The maturation of cellular acuity coincides with maturation of retinal and LGN synaptic organisation and of optic nerve myelination.

    ELECTROPHORETIC ANALYSIS OF HLA-DR2 MOLECULES ISOLATED FROM HLA-Dw2 AND HLA-Dw 12 CELL LINES (1985)

    Notes: To answer the question of whether or not polymorphism exists among HLA-DR2 molecules derived from cells homozygous for HLA-DR2, but expressing different HLA-D specificities, HLA-DR2 molecules were isolated from HLA-Dw2 and HLA-Dw12 homozygous cells using a monoclonal antibody operationally monospecific for HLA-DR2, and were compared to each other by two-dimensional gel eletrophoresis. No electrophoretically discernible polymorphism was found in either the heavy or the light chain subunits of the HLA-DR2 molecules. These findings are in marked contrast with previous observations that each of the HLA-DR4-associated HLA-D clusters expresses an electrophoretically distinct HLA-DR4 light chain.

    GENETIC CONTROL OF ANTI-DNP RESPONSE TO DNP-BSA GIVEN BY CONTINUOUS INFUSION TECHNIQUE (1979)

    Notes: Ten inbred strains of mice were administrated with dinitrophenyl-bovine serum albumin (DNP-BSA) at a dose of 30 or 300 μg/day by continuous infusion technique. Anti-DNP plaque-forming cells (PFC) in their spleens were assayed 10 to 12 days after the beginning of the infusion. NZB, BALB/c, C3H/He and NC strains were high responders to both doses of DNP-BSA. KK, SII and TES strains were low responders: the antibody response was low to the dose of 30 μg/day, and high to the dose of 300 μg/day. Breeding tests between high responder BALB/c and intermediate responder DDD mice indicated that the immune response was largely controlled by a gene linked to the H-2 complex. Similar studies with high responder NZB and low responder TES mice suggested an involvement of a few genes: at least one of the controlling genes may be linked to the H-2 complex.

    Spontaneous regression of pituitary mass in temporal association with pregnancy (1987)

    Notes: Summary We have encountered a case of a pituitary mass which emerged and enlarged during pregnancy in a 29-year-old woman. On CT scaning the mass disappeared over the course of four months postpartum and was followed by pituitary hypofunction. The hypofunction was restricted to ACTH, GH, and PRL. The visual field defects, bitemporal hemianopsia, disappeared with disappearance of the pituitary mass on CT scanning, indicating that such deficits during this period were reversible. Based on the clinical course and laboratory data, this case is thought to have been lymphocytic adenohypophysitis. It was concluded that among pituitary tumors developing during pregnancy there are some such cases which do not require surgical therapy.

    Properties of LGN cells in kittens reared with convergent squint: A neurophysiological demonstration of amblyopia (1976)
    Springer
    Experimental brain research 25 (1976), S. 63-77 
    Details
    ISSN: 1432-1106
    Keywords: Kitten LGN ; Single cell ; Convergent squint ; Visual acuity ; Amblyopia
    Source: Springer Online Journal Archives 1860-2000
    Topics: Medicine
    Notes: Summary The spatial resolution of LGN cells has been studied in 4–5 month old kittens raised with convergent squint surgically produced in one eye at the age of 3–4 weeks. The ‘sustained’ cells which received inputs from the central retina of the squint eye showed significantly poorer spatial resolution (determined by the highest spatial frequency of a sinusoidal grating to which a cell responded with modulated firing) than those which received inputs from the central retina of the normal eye. The spatial resolution of cells which received inputs from the peripheral retina of the squint eye was not different from that of cells receiving inputs from the peripheral retina of the normal eye. The visual latency of ‘sustained’ cells which received an input from the area centralis of the squint eye was considerably lengthened and the response showed a sluggish onset. Thus the most important clinical symptom of amblyopia, namely the reduction of foveal visual acuity, has been demonstrated in kittens raised with unilateral vonvergent squint. The results suggest that the lesion responsible for amblyopia due to squint might be a functional degeneration of the high spatial frequency tuning cells in the pathway prior to the visual cortex, i.e. in the retina or LGN.

    Immunohistochemical study of Rathke's cleft cyst (1988)

    Topics: Medicine
    Notes: Summary An immunohistochemical study was made of ten cases of asymptomatic and three cases of symptomatic Rathke's cleft cyst. The cysts in the asymptomatic cases had monolayer columnar or cuboidal epithelium. Within the epithelium, cells which were positive for at least one of the pituitary hormones were found. The rate of positive reactions for these six pituitary hormones was between 70% and 100%. In contrast, the cysts in the symptomatic cases had an epithelium which was partly stratified squamous and partly squamous epithelium, and none of the pituitary hormones were found in them. Therefore, when a Rathke's cleft cyst enlarges to the extent that clinical symptoms are produced, we consider that changes have already occurred in structure and function of the cyst epithelium. In addition, we believe there is a tendency for monolayer epithelia to undergo squamous metaplasia and for cells which are positive for pituitary hormones to change into non-granulated cells.

    Immunological and haematological changes during high-dose immunoglobulin therapy in an infant with autoimmune neutropenia (1987)

    Notes: Abstract High-dose immunoglobulin (HD-Ig) therapy was given to an infant with autoimmune neutropenia (AIN), and antineutrophil autoantibodies (ANAA). The patient's absolute neutrophil count in peripheral blood increased from 300/ mm3 to 3000–4000/mm3 7 days after treatment. Although the neutrophil count gradually decreased thereafter, transient increases were observed after each single booster infusion repeated at 3-week intervals. By continuing this treatment, clinical symptoms were markedly alleviated, and the patient's susceptibility to infection was reduced. The increase in neutrophils showed a positive correlation with the increase in serum IgG, and with the increase in the ratio of T helper/T suppressor cells. The neutrophil-bound IgG level and serum lysozyme level were decreased after HD-Ig therapy.
