    Effect of temperature on development rate and intrinsic rate of increase ofAphis gossypii reared on greenhouse cucumbers (1994)

    Topics: Biology
    Notes: Abstract Thermal requirements for development and life table statistics ofAphis gossypii Glover (Homoptera, Aphididae) were determined over a range of constant temperatures from 10 to 30°C. The lower development threshold and the sum of effective temperatures were 6.9°C and 90.1°C, respectively, for preimaginal development, and 5.8°C and 113.6°C from birth to the onset of reproduction. Mean total fecundity ranged from 36 larvae per female at 10°C to 76 larvae at 30°C. On a time scale of days, net reproductive rate (R o ) increased with increasing temperature while generation time (T) decreased causing the intrinsic rate of increase (r m ) to increase linearly from 0.115 to 0.465. On a day-degree scaler m only varied from 0.019 to 0.028 because the growth ofR o was compensated by an increase inT with increase in temperature. The nearly constantr m in terms of day-degrees, over a wide range of temperatures, greatly simplifies the prediction of future population numbers ofA. gossypii.

    Chronic viral hepatitis B and C: an argument against the conventional classification of chronic hepatitis (1994)
    Springer

    Notes: Abstract The classification of chronic hepatitis distinguishing benign chronic persistent hepatitis from severe chronic active hepatitis was constructed without knowledge of well-defined aetiological factors. Better understanding of the different hepatitis-viruses has shed new light on this subject. Chronic viral hepatitis B and C each show typical histological patterns. The validity of the conventional classification has been evaluated by a comparative study of chronic viral hepatitis B and C. 130 biopsies from 110 patients with chronic hepatitis C (CH-C) proven serologically by antibodies (second generation testing) were compared with 105 biopsies from 73 patients with chronic hepatitis B (CH-B). These were scored semi-quantatively. In CH-C, lymphoid follicles and/or aggregates were found in 88.5%, fatty degeneration in 51%, bile duct lesions in 46.2%, and Mallory body-like material in the hepatocytes in 9.2%. The portal lymphocytic infiltration generally predominated over the necro-inflammatory lesions of the parenchyma. Chronic persistent hepatitis (defined by the presence of portal hepatitis) was present exclusively in CH-C. Chronic lobular hepatitis was found exclusively in CH-B. We conclude that the histological criteria described for CH-C are highly suggestive of the diagnosis, that the artificial subdivision of chronic hepatitis into CPH and CAH is obsolete and that the histological assessment of chronic hepatitis should consist of a grading of inflammatory activity (minimal, mild, moderate, severe) and staging of fibrosis (extent of distortion of architecture). The final diagnosis should be based on the demonstration of the aetiological agent.

    Prizidilol (SK & F 92657), a new vasodilator with beta-blocking properties in the treatment of essential hypertension (1982)

    Notes: Summary The antihypertensive effect of a new vasodilator with betablocking properties (SK & F 92657) was investigated in 10 patients with mild to moderate essential hypertension. After a mean treatment period of 26,5 weeks (6,5–49 weeks) blood pressure was significantly reduced, from 168±22/106±6 mmHg to 144±19/94±12 mmHg (p〈0.05 and 0.025). The mean dose was 410 mg (100–700 mg). Heart rate decreased slightly from 77±12 to 70±8 beats/min. Plasma renin activity and plasma aldosterone showed only minor changes. Nausea, heavy dreams, facial and hand flushing and mild depression were reported as side effects. In most patients the symptoms disappeared without reduction in the dose. In one patient anaemia developed after 7 weeks and treatment with prizidilol was stopped. A slight but statistically significant decrease in haemoglobin concentration of 1.1±0.6 g/dl was observed in 5 of the 10 patients (p〈0.02). Thus, a mean dose of prizidilol of 410±242 mg/day had a mean blood pressure lowering effect of 24/12 mmHg. In 7 of the 10 patients (70%) diastolic blood pressure could be reduced to 95 mmHg or less. However, the observed haematological side-effects should be carefully monitored in further studies and may limit the clinical use of prizidilol.

    Determination of some trace elements in the thyroid gland by INAA (1991)
    Springer
    Journal of radioanalytical and nuclear chemistry 149 (1991), S. 267-274 
    Details
    ISSN: 1588-2780
    Source: Springer Online Journal Archives 1860-2000
    Topics: Chemistry and Pharmacology , Energy, Environment Protection, Nuclear Power Engineering
    Notes: Abstract Neutron activation analysis without radiochemical separation was used for simultaneous analysis of eight trace elements in thyroid glands, obtained as necroptic material from persons not suffering from diseases of this gland. Inorganic standard solutions were used for calculations of concentrations of measured elements. Concentrations are expressed in ppm, or ppb. IAEA reference materials were used for quality assurance of analyses. From analyses of 42 thyroids concentration levels of Se, Cs, Sc, Fe, Cr, Zn, Co, and Rb and their variances in the thyroids were calculated. These results might serve as comparison material for medical research of pathological and functional changes in thyroid glands.

    Notes: Abstract 126 samples of scalp hair from inhabitants of Central Bohemia were searched for content of zinc, cobalt, cesium, chromium, scandium, selenium, and iron, for the purpose of medical research. Simultaneous determination of the elements was made by INAA. Inorganic standards were used for calculation of concentrations of elements. Quality assurance was checked by IAEA certified reference material and by internal standard mixed human serum. Statistical results are expressed in ppm, or ppb. Both normal and, if necessary, log-normal distributions of elements are presented, and types of distribution curves are verified statistically on 95% level of probability.

    Notes: Abstract Concentration levels of eight trace elements in 120 samples of human blood serum were investigated by Instrumental Neutron Activation Analysis (INAA) for the purpose of medical research. The elements Co, Cr, Cs, Fe, Rb, Sc, Se, and Zn were simultaneously determined by the relative method in comparison with inorganic standards treated under identical conditions. The process of analysis and its reliability was checked using human serum and IAEA certified reference material. Statistical results are expressed in ppm or ppb. Both normal and, if necessary, log-normal frequency distributions of all elements determined are presented, types of distribution curves are verified statistically on 95% level of probability.
