    Magnetic flux noise in thin-film rings of YBa2Cu3O7−δ (1988)

    Notes: The low-frequency magnetic flux noise in thin-film rings of YBa2Cu3O7−δ (YBCO) is measured over the temperature range 1.3–125 K by means of a dc superconducting quantum interference device (SQUID) maintained at liquid-helium temperatures. Below the transition temperature Tc of the YBCO, the spectral density of the noise scales as 1/f, where f is the frequency, and generally increases with increasing temperature. The magnitude of the noise depends strongly on the microstructure of the film, and is lowest for a sample which is predominantly oriented with its c axis perpendicular to the substrate. These results imply that SQUID's and flux transformers of YBCO must be fabricated from highly oriented films to produce good resolution at low frequencies.

    Notes: Summary Three cytopathic rotavirus isolates were recovered from young rabbits affected by an enteric syndrome. The three isolates, when compared by cross serum-neutralization tests, were found to be of the same serotype. Cross neutralization occurred also between a representative of the rabbit isolates and one strain of bovine rotavirus.

    FCE 20696, a new synthetic immunomodulator: Immunopharmacological profile (1989)

    Notes: Abstract A preliminary characterization of the immunopharmacological profile of the new immunomodulating agent FCE 20696 (6H,6 [2-(dimethylamino)-ethoxycarbonyl]-dibenzo[b,d]pyran-HCl) was performed in mice. Single i.p. doses of this chemical, concomitantly given with the antigen, increased the antibody response and decreased the delayed hypersensitivity reaction to a suboptimal dose of SRBC, the active doses ranging from 6.25 to 50 mg/kg. No activity was observed using a full antigen dose. Macrophage cytotoxic activity was enhanced 2–4 days after a single i.p. treatment with 50 and 10 mg/kg. Spleen cell proliferation to T and B mitogens was inhibited by a single dose of 30 mg/kg given i.p. 6 days before the test, or by 10 mg/kg×3 days ending one day before the test. Finally, generation of suppressor cells was enhanced by the compound, given p.o. biweekly for at least 7 weeks, at doses ranging from 0.1 to 10 mg/kg. Collectively taken, these data suggest that FCE 20696 has a broad range of immunomodulating activities and that macrophages and suppressor cells are presumed to be the main targets of its pharmacological activity.

    Antigen specific, suppressor cells induced by the immunomodulator FCE 20696 in aged NZB/WF1 mice (1986)

    Notes: Abstract FCE 20696 is a new synthetic immunomodulating agent, active on some manifestations of the autoimmune disease of NZB/WF1 mice, in which a disorder of T suppressor cells (SC) has been described to be of pathogenetic relevance. The ability of FCE 20969 to induce SC in NZB/WF1 mice, which are then able to specifically inhibit the production of anti autologous red blood cells antibodies (aRBC Ab), was investigated. NZB/WF1 mice were chronically treated with the compound starting from the ninth week of age, sacrificed at different times and their spleen cells transferred to 9 weeks old, syngeneic mice. In donor animals SC were induced by rat RBC, whereas in the recipients the suppressive activity of transferred cells was evaluated from the appearance of aRBC Ab induced by the same antigen. The results show that antigen specific SC were present in both FCE 20696 treated and control young animals. In older controls, SC couldn't be induced, whereas in treated animals SC were present and able to transfer suppression into the recipents. FCE 20696 was active at 1.5 mg/Kg.

    Notes: Summary The plasma levels and myocardial content of verapamil and its metabolites norverapamil, N-dealkylverapamil and N-dealkylnorverapamil were determined in 15 patients with valvular [3] or ischaemic [12] heart disease. The mean myocardial plasma concentration ratio (M/P) was 7.05 for verapamil, 11.45 for norverapamil, 8.93 for N-dealkylverapamil, and 11.33 for N-dealkylnorverapamil, with great interpatient variability. The highest M/P ratios of verapamil were generally found in patients with the lowest plasma levels, suggesting that saturable tissue uptake may occur.

    Italian experience regarding the prevention of Duchenne and Becker muscular dystrophies (1988)

    Notes: Abstract The indirect approach to carrier detection and prenatal diagnosis of Duchenne and Becker muscular dystrophies based on the study of DNA polymorphisms closely linked to this gene has been followed by five Italian laboratories in the study of 106 pedigrees. Out of 354 women studied up to 1 May 1987, 147 were identified as carriers because of pedigree information and/or of increased creatine phosphokinase (CPK) values. Of the remaining 207, 184 could be assigned to three arbitrarily defined risk categories (low, intermediate and high) using linkage analysis. This disaggregation of women at risk is clearly more useful than that defined before DNA analysis, in which the same 184 women could be assigned only to the low or intermediate risk categories. Prenatal diagnosis was theoretically possible in 90% of carrier women, and was actually performed in 14 pregnancies, which led to the identification of four affected male foetuses, one also having Down syndrome.

    A comparison of rotavirijs strains of bovine, simian and porcine origin (1985)

    Notes: Abstract Three rotavirus strains of bovine, simian and porcine origin, respectively, were compared. The 3 viruses induced a classic rotavirul infection in newborn, conventionally reared calves. The cross neutralization tests revealed an antigenic identity of simian and porcine rotaviruses and a slight serologic correlation of these two viruses with the bovine rotavirus strain. However, in reciprocal cross protection tests carried out in calves, the simian rotavirus antiserum afforded weak protection to challenge infection with either the porcine or the bovine viruses. By contrast, the protective level of the bovine and the porcine rotavirus antisera was relatively high. It was speculated that the 81/36F bovine rotavirus could be considered, tentatively, as an antigenic reassortant rotavirus strain.

    Field trial evaluation of an inactivated rotavirus vaccine against neonatal diarrhea of calves (1987)

    Topics: Medicine
    Notes: Abstract Field trials were conducted using an inactivated rotavirus vaccine for prevention of calf neonatal diarrhea. For the trials, 458 pregnant cows from 26 herds were involved. In each herd, cows which had been inseminated within a period of two months were selected and randomly subdivided in two groups. Cows in one group (248 head in total) were vaccinated 6 weeks before calving and again 4 weeks later; cows in the other group (210 head in total) were left as unvaccinated controls. At calving, colostrum was collected from each cow and stored at -30°C until used for feeding calves. The newborn calves, beginning the second day of life and for the next 7–10 consecutive days, each was fed a daily supplement of 400 ml of colostrum from its dam. The diarrhea occurred in 86 (40.9%) calves that had received colostrum from unvaccinated dams (normal colostrum), and in 7 (2.8%) calves which were fed colostrum from vaccinated dams (immune colostrum). The disease was very severe in the normal colostrum-fed calves and 52 of them died. Those calves which survived the disease underwent a significant loss of condition. By contrast, the 7 immune colostrum-fed calves displayed a rather mild enteric condition, and all recovered without any sequela being observed.
