    Notes: Abstract: We have measured the dissociation of 8B in the Coulomb field of 208Pb at Ein=51.9 MeV/nucleon and extracted the cross section of the 7Be(p,γ)8B reaction at 0.4 ≤ Erel≤ 3 MeV, which is of importance for the 8B solar-neutrino production rate. The extracted astrophysical S17 factors are consistent with our earlier Coulomb dissociation measurement, and agree with the values deduced from the direct capture measurements by Filippone et al., Vaughn et al. and Hammache et al. The S factor at zero energy was extracted to be 18.9±1.8 eV-b with the help of theoretical energy-dependence.

    Notes: Abstract New neutron-deficient isotopes,197Rn,197mRn, and200Fr have been produced and identified on the basis of genetic correlations in the166Er(36Ar,5n)197Rn (Elab=186, 200 MeV), and169Tm(36Ar,5n)200Fr (Elab=186 MeV) reactions. The evaporation residues were separated from the beam by using a gas-filled recoil separator and implanted onto a position-sensitive solid-state detector. The α-decay energies (half-lives) of197Rn,197mRn and200Fr have been determined to be 7261±30 keV (51 −15 +35 ms), 7370±30 keV (18 −5 +9 ms), and 7500±3O keV, (570 −140 +270 ms), respectively.

    Identification of an abdominal ganglion neuron antagonizing L7-driven gill contraction in Aplysia (1999)

    Notes: Abstract Gill motor neuron L7-induced longitudinal shortening of the gill in Aplysia kurodai and A. juliana was suppressed when extracellular stimuli were applied to a restricted dorsal central region of the abdominal ganglion. We found a neuron there which antagonized the L7-driven contraction. Since the contraction was suppressed when the identified neuron was activated simultaneously with L7, we refer to the newly found neuron as “Anti-L7”. Anti-L7 did not change the L7 impulse generation in the abdominal ganglion. No direct synaptic connection from L7 to Anti-L7 was detected. A fluorescent dye injected into the soma of Anti-L7 revealed that the neuron sent axonal branches to the branchial nerve. These results may show that Anti-L7 antagonizes L7 at the periphery inside the gill, rather than in the abdominal ganglion. EJPs induced by L7 were unaffected by Anti-L7. Activation of Anti-L7 alone did not induce any change in tone or membrane potential of the gill musculature. The suppressive effect of Anti-L7 lasts many seconds after the cessation of a train of Anti-L7 impulses. The results may suggest that the suppression is mediated through an inhibitory neuromodulatory mechanism without inhibition of L7 itself.

    Intrahepatic cholangiocarcinoma with marked hypervascularity (1999)

    Notes: Abstract Two rare cases of small intrahepatic cholangiocarcinoma with marked hypervascularity are reported. Dynamic computed tomographic and magnetic resonance images of the two cases revealed strong enhancement of the whole tumor on the early phase and prolonged enhancement on the late and delayed phases. In both cases, the tumors turned out to be well-differentiated tubular cholangiocarcinoma that contained a large number of tumor cells and few interstitial fibrous tissues. These results suggest that some intrahepatic cholangiocarcinoma should be differentiated from other hypervascular hepatic tumors, especially hepatocelluar carcinoma, and that prolonged enhancement of the tumor on late and delayed phases of dynamic images could be of diagnostic value.

    Alpha-amylase inhibitor increases plasma 3-hydroxybutyric acid in food-restricted rats (1995)

    Notes: Abstract The effect on energy metabolism of delayed absorption of starch by inhibition of α-amylase was examined by considering levels of plasma glucose and 3-hydroxybutyric acid (3-OHBA) in rats. Addition of α-amylase inhibitor (αAI) to a high starch diet delayed the plasma glucose response after feeding: peak plasma glucose levels in the control group occurred 15 min after feeding, whereas in the αAI group this peak did not occur until 30 min after. The total plasma glucose response was not different between the two groups. Plasma 3-OHBA levels 1 day after food restriction increased approximately five-fold in both groups. After 3 days of food restriction, the αAI group maintained the same level of plasma 3-OHBA as after 1 day of food restriction, while the control group showed significantly decreased levels of 3-OHBA. After 3 days of food restriction, plasma insulin levels were significantly decreased in the αAI group compared with the corresponding levels of the control group and with levels before the restriction. There was no significant difference in body weight between the two groups. These findings suggest that delayed hyperglycemia due to delayed absorption of starch following αAI loading may attenuate insulin secretion, leading to altered metabolism of 3-OHBA during the delayed response to energy deficit.

    Notes: Abstract Correlation between T cell phenotypes, especially activated T cells expressing early (EA1) and late (HLA-DR) activation antigens and clinical features were investigated in 22 patients with systemic lupus erythematosus (SLE) of childhood onset. Percentages of T cells expressing EA1 and HLA-DR in 22 patients with SLE were significantly higher than those in controls. Comparison of T cell phenotypes between patients with active and inactive SLE showed that eight patients with active disease had significantly increased percentages of HLA-DR positive T cells than 14 with inactive disease (P〈0.01). Serial examinations showed that the percentages of HLA-DR positive T cells were decreased after therapy in seven with active non-renal or active non-renal and renal diseases but not in one with only active renal disease. A possible significance of T cells expressing EA1 and HLA-DR in the management of patients with SLE is discussed.

    Ultrastructural changes associated with reversible and irreversible suppression of electrical activity in olfactory cortex slices (1970)
    Springer

    Topics: Medicine
    Notes: Summary The fine structure and electrical activity were studied in thin brain sections prepared from the olfactory cortex of the guinea pig and incubated in vitro in standard and modified conditions. In the standard medium, the potential response was maintained with no marked changes for 4–5 hours and thereafter gradually decreased. The ultrastructure of the tissue was well preserved for the initial 2 hours of incubation. After incubation for 5 hours, many empty spaces were noted. Some dendritic stumps lost fine internal structure, but most of the synapses were apparently normal. Cyanide suppressed the potential response, and caused swelling of the nerve terminals and a decrease in the number of synaptic vesicles. The recovery of the response in the standard medium was not accompanied by a full restoration in the fine structure. If slices were incubated in the absence of glucose and oxygen, with cyanide in glucose-free medium, or at a low temperature, the potential response was irreversibly depressed. In these slices, numerous wide spaces of low electron density were noted which were concluded to have been derived, at least partly, from the swollen dendrites.

    Notes: Summery.  Varicella-zoster virus glycoproteins were purified by using monoclonal antibodies and analyzed for their effects on cell-free virus infection. Preinfection treatment of cells with gH:gL reduced the infection efficiency and increased the number of unadsorbed virus. Postinfection treatment of cells with gB increased the infection efficiency, but that with gE:gI reduced it. Treatment of gE:gI and gH:gL with neuraminidase (NA) abolished their inhibitory activity and the plaque formation was enhanced by NA treatment of glycoproteins and cells. Glycoproteins exhibited their diverse activities despite their common role in viral penetration, and sialyl residues were responsible for their function in cell-free virus infection.
