    3′,5′-Cyclic Guanosine Monophosphate Activates Mitogen-Activated Protein Kinase in Rat Pinealocytes (1999)

    Notes: Abstract : The role of 3′,5′-cyclic guanosine monophosphate (cGMP) in the activation of mitogen-activated protein kinases (MAPKs) was investigated in rat pinealocytes. Treatment with dibutyryl cGMP (DBcGMP) dosedependently increased the phosphorylation of both p44 and p42 isoforms of MAPK. This effect of DBcGMP was abolished by PD98059 (a MAPK kinase inhibitor), H7 (a nonspecific protein kinase inhibitor), and KT5823 [a selective cGMP-dependent protein kinase (PKG) inhibitor]. Elevation of cellular cGMP content by treatment with norepinephrine, zaprinast (a cGMP phosphodiesterase inhibitor), or nitroprusside was effective in activating MAPK. Natriuretic peptides that were effective in elevating cGMP levels in this tissue were also effective in activating MAPK. Our results indicate that, in this neuroendocrine tissue, the cGMP/PKG signaling pathway is an important mechanism used by hormones and neurotransmitters in activating MAPK.

    Primary low cerebrospinal fluid pressure syndrome with galactorrhea: findings at MR imaging (1996)

    Notes: A case of primary low cerebrospinal fluid (CSF) pressure syndrome with galactorrhea is reported. Magnetic resonance imaging demonstrated diffusely enhanced meninges, edematous brain, and enlarged pituitary gland. Coincidental enlargement of pituitary gland and edematous brain due to low CSF pressure compressed the pituitary portal system. The 1ow-perfused anterior lobe of pituitary gland would be the mechanism of galactorrhea.

    Merkel cells participate in the induction and alignment of epidermal ends of arrector pili muscles of human fetal skin (1996)

    Notes: The follicular proximal ends of arrector pili muscles anchor the bulge areas of human hair follicles. However, the location of the ends of these muscles towards the epidermis, especially the fine points of attachment, is not fully understood. Conventional serial sections of the scalp skin of a 12-month-old infant were examined. Most of the distal ends were situated in the upper dermis. while some seemed to be in close contact with the epidermal basal layers. In vertical sections of the scalp skin of 16-week-old fetus, double immunoenzyme staining showed a close topographic correlation between the epidermal ends of the arrector pili muscles and the epidermal and dermal Merkel cells. These findings allow speculation that fetal Merkel cells participate in the induction and alignment of arrector pili muscles.

    Specific detection of anti-cell surface antibodies in herpes gestationis sera (1996)

    Topics: Medicine
    Notes: Abstract We examined 42 herpes gestationis sera with immunofluorescence of normal human skin sections, and found that anti-keratinocyte cell surface antibodies were detected specifically in 10 herpes gestationis sera. The diagnosis of these herpes gestationis cases was confirmed by detecting antibodies against the 180 kD bullous pemphigoid antigen with immunoblotting of its fusion protein. The results of immunoadsorption assay using baculoproteins of both pemphigus vulgaris and pemphigus foliaceus antigens indicated that the herpes gestalionis sera did not recognize common pemphigus antigens. Immunoblotting of human epidermal extracts and immunofluorescence of various tissues also suggested that the sera did not recognize any other desmosomal components or paraneoplastic pemphigus antigens. The significance of this reactivity is unclear. However, because no control bullous pemphigoid sera showed this reactivity, it may suggest a different pathophysiology between herpes gestationis and bullous pemphigoid.

    Unilateral facial angiofibromas—a segmental form of tuberous sclerosis (1996)

    Notes: Summary Multiple facial angiofibroma are thought to be a pathognomonic and common, feature of tuberous sclerosis. In contrast, it is rare to see multiple angiofibroma limited to one side of the face. We have studied a patient with multiple angiofibroma of one cheek, in order to search for other manifestations of tuberous sclerosis and to determine the histochemical identity of the angiofibroma. No evidence of other pathology known to be associated with the tuberous sclerosis complex was uncovered. Histopathology of the unilateral lesions revealed focal fibroplasias and positive cellular staining for factor XIIIa and vimentin similar to that described for bilateral angiofibroma. We suggested that the segmental expression of tuberous sclerosis, in the form of unilateral facial angiofibroma may result from a postzygotic mutation.

    Anodically deposited manganese-molybdenum oxide anodes with high selectivity for evolving oxygen in electrolysis of seawater (1999)

    Notes: Abstract Manganese-molybdenum oxide electrodes were prepared by anodic deposition on an IrO2-coated titanium substrate at a constant current density of 600Am−2 from baths containing 0.2M MnSO4 and 0–0.1M Na2MoO4 at 90∘C and pH 0.5. These electrodes were characterised for oxygen evolution in the electrolysis at 1,000Am−2 in 0.5M NaCl solution at 30∘C and pH 8 or 12. The most active and stable oxygen evolving anode exhibited 100% efficiency for oxygen evolution, and an efficiency of 98.5% for over 1,500 h at pH 12 and of 96.5% for over 2,800 h at pH 8 of continuous electrolysis. X-ray diffraction measurement and XPS analysis indicated that the deposits consist of a nanocrystalline single γ-MnO2 type phase, and manganese and molybdenum in the deposits are in the Mn4+ and Mo6+ states. The electrochemical studies showed that the manganese-molybdenum oxide electrodes drastically reduced the electrocatalytic activity for chlorine evolution to the undetectable level, resulting in 100% efficiency for oxygen evolution, although the addition of molybdenum slightly increased the oxygen overpotential.

    Notes: Abstract We have analyzed muscle biopsy specimens from polymyositis patients who are also positive for human T cell lymphotropic virus type I (HTLV-I) using both immunohistochemistry for surface antigens of lymphocytes and macrophages and in situ polymerase chain reaction for HTLV-I proviral DNA on the same sections. We found HTLV-I in CD4+ cells but not in macrophages. This finding suggests that most of the HTLV-I-containing CD4+ cells are not macrophages but lymphocytes.
