    Notes: We have studied the molecular mechanism of the negative regulation by flgM of the late operons of the flagellar regulon of Salmonella typhimurium. A 7.8 kDa protein that was identified as the flgM gene product was purified to homogeneity; its amino-terminal sequence was identical to the deduced sequence except for the lack of the initiating methionine. The purified FlgM repressed transcription from the fliC promoter, one that is activated by the sigma factor, FliA (σF). No DNA-binding activity was detected in FlgM. Chemical cross-linking experiments showed that the purified FlgM bound to σF and disturbed Its ability to form a complex with RNA polymerase core enzyme. These results indicate that FlgM is a novel type of negative regulator that probably inactivates the flagellum-specific sigma factor through direct interaction, i.e. it is an anti-sigma factor.

    Notes: The disaccharide content of the chondroitinase-digestible glycosaminoglycans (GAGs) extracted from 6–mm skin punch biopsies from the atrophic and sclerotic skin of two patients with Werner's syndrome (WS) were determined using high-performance liquid chromatography after 1–phenyl-3–methyl-5–pyrazolone labelling. The total amount of main disaccharides was significantly decreased in the atrophic lesions of WS. In the atrophic forearm skin, the decrease in the main disaccharide unit of hyaluronic acid, ΔDi-HA, and the increase in the ratio of the main disaccharide unit of dermatan sulphate, ΔDi-4S, to ΔDi-HA were significant vs. normal control (P 〈0.01 and 0.05, respectively). The sclerotic skin showed an increase in ΔDi-4S (DS) (P 〈 0.05) and a decrease in ΔDi-HA (P 〈 0.02) compared with normal controls, as well as a significantly higher ratio of ADi-4S (DS)/ΔDi-HA compared with normal controls (P 〈 0.0002) and systemic sclerosis patients (SSc; P 〈 0.02). No other statistical difference was found in the amount of each main disaccharide unit between the sclerotic skin of WS and SSc. Histological examination revealed that the atrophic skin showed thinning of the dermis with a slight increase of fine collagen bundles, whereas the sclerotic skin demonstrated a thickened dermis with prominent deposition of fine collagen bundles in the deep dermis. In SSc, thickening of the whole dermis, composed of hyalinized or swollen collagen bundles, was found. These results suggest mat alterations of disaccharide components in WS may differentiate the atrophic skin changes from the sclerotic skin changes, while the mechanisms for abnormal fibrosis remain to be elucidated.

    Notes: We report a 57-year-old woman with systemic sclerosis (SSc) who died suddenly, following a haemoptysis. At post-mortem, systemic necrotizing angiitis of small vessels was observed in several organs. Necrotizing angiitis has been reported as a rare complication of systemic sclerosis, and is usually lethal.

    A scleroderma-like variant of recessive dystrophic epidermolysis bullosa? (1993)

    Notes: We report a 17-year-old Japanese girl with typical clinical features of recessive dystrophic epidermolysis bullosa (RDEB). She had initially been diagnosed as suffering from systemic sclerosis because her skin became sclerotic at the age of 21 months, and there was no apparent blister formation. She subsequently developed severe dystrophic skin changes. However, there was histological evidence of subepidermal cleavage, diminished basement membrane zone immunohistochemical reactivity to anti-type VII collagen monoclonal antibody, and markedly decreased numbers of anchoring fibrils on electron microscopy. Although both the clinical and laboratory findings support a diagnosis of RDEB, we cannot exclude the possibility that our patient might represent a new clinical entity.

    Bundles of amyloid precursor protein-immunoreactive axons in human cerebrovascular white matter lesions (1994)

    Notes: Abstract Cerebral white matter lesions commonly observed in Binswanger's disease, multi-infarct encephalopathy and elderly people are neuropathologically characterized by diffuse incomplete demyelination and considered to be ischemic in nature. Arteriolosclerosis in the white matter is a common feature in these white matter lesions. To investigate a possible alteration of the distribution of amyloid precursor protein (APP), chromogranin A (CgA) and synaptophysin (Syn) in such white matter lesions, we examined 15 cases with white matter lesions and 5 without white matter lesions. Many bundles of axons with APP-like immunoreactivity (LI) were observed particularly in mild white matter lesions. Such bundles of axons showed similar but less intense CgA-LI and Syn-LI. They appeared to occur in areas with many ameboid or ramified microglia labeled with anti-leukocyte common antigen and few astrocytes labeled with anti-glial fibrillary acidic protein. In the center of moderate of severe white matter lesions bundles of axons with APP-LI were never observed. Since APP, CgA and Syn undergo fast axonal transport, and since following ischemic insults to central nervous system microglial reaction occurs earlier than astroglial changes, our results suggest that axonal damage, which induces disturbance of fast axonal transport, can occur even in the early stage of white matter lesions.

    Notes: A numerical model of time-dependent gas shielded metal arc is described, which wasdeveloped in order to make clear the kinetics of arc plasma together with metal transfer. It ispossible to calculate and visualize time-dependent temperature and fluid flow field of argonshielded metal arc plasma with the grow-up and the subsequent detachment of the liquid metal dropat the wire tip. Numerical calculation shows that the arc shape in globular transfer abruptly changesat the moment of metal drop detachment. Whereas, the spray transfer arc seems to be stable andalmost does not fluctuate with metal transfer

    Selective Protein Adsorption Property and Structure of Nano-Crystalline Hydroxy-Carbonate Apatite (2006)

    Notes: The selective protein adsorption property and the local structure around carbonate ions of nanocrystalline hydroxy-carbonate apatite were examined in this study. Considerable change in the selectivity in the adsorption of BSA and β2-MG was observed due to the incorporation of thecarbonate ions in hydroxyapatite lattice. Since the protein adsorption property seems to be related to the surface charge density of hydroxyapatite due to the carbonation, the chemical states of theincorporated carbonate ions were examined by the 31C CP-MAS NMR spectroscopy. At least four peaks assignable to carbonate ions in A-site(OH-) and B-site(PO4 3-) were observed in 13C CP-MASNMR spectrum. Thus, we must take into consideration that the surface charge distribution and the decrement of polar groups such as OH- groups due to the distribution of carbonate ions in both Aand B-sites of the hydroxyapatite lattice are particularly favorable for β2-MG adsorption rather than for BSA adsorption

    Notes: Summary A large-scale, prospective study of tardive dyskinesia (TD) was performed in 11 psychiatric facilities in Japan. A total of 1595 psychiatric patients were enrolled in this study in 1987. The progress of these patients, with the exception of 490 dropouts, has now been followed up to 1988. The prevalence of TD at study entry was 7.6%, the annual incidence rate was 3.7% and the annual remission rate was 28.7%. Newly developed TD patients tended to be older, to have undergone more psychosurgery, and to have had lower neuroleptic doses than the patients who had not developed TD, whereas no specific variable could be detected as a factor associated with remission of TD. The results suggest that the incidence of TD is lower in Japan than that in Europe and North America.
