16. Análise cladística de Conulariidae Walcott (Neoproterozóico-Triássico): caracterizando e definindo um grupo de cnidários extintos / Cladistic analysis of the Conulariina Miller and gurley 1896 (Cnidaria, Scyphozoa; Vendian/Triassic)
A análise cladística de Conulariidae (Cnidaria) é aqui apresentada, e está fundamentada na hipótese de que os agrupamentos taxonômicos (famílias, subfamílias), propostos no ?Treatise on Invertebrate Paleontology? (TIP), não são filogeneticamente válidos. O estudo apresentado levou em consideração a revisão do material depositado em coleções d

17. MULTIPLICAÇÃO IN VITRO DE Cedrela fissilis Vell. / IN VITRO MULTIPLICATION OF Cedrela fissilis Vell.
This study had as objective to study the in vitro regeneration of cedar (Cedrela fissilis Vell.), a native tree of economic interest, belonging to Meliaceae family. For seeds desinfestation, different treatments with sodium hypochlorite in different concentration and immersion times were tested combined with differents culture mediums. To establish the nodal

19. New method for an occupational dust challenge test.
OBJECTIVES--Specific challenge tests with a suspected allergen in the workplace are standard to confirm the diagnosis of asthma. Facilities for sophisticated exposure tests are available only in a few institutions. A pilot study was carried out that used a novel approach for an occupational dust challenge test with a rotahaler. METHODS--Nine consecutive pati

21. An Increase in Pectin Methyl Esterase Activity Accompanies Dormancy Breakage and Germination of Yellow Cedar Seeds1
Pectin methyl esterase (PME) (EC 3.1.1.11) catalyzes the hydrolysis of methylester groups of cell wall pectins. We investigated the role of this enzyme in dormancy termination and germination of yellow cedar (Chamaecyparis nootkatensis [D. Don] Spach) seeds. PME activity was not detected in dormant seeds of yellow cedar but was induced and gradually increase

22. Quantitative versus qualitative analysis of peak expiratory flow in occupational asthma.
BACKGROUND: Peak expiratory flow rates (PEF) are often used to confirm the diagnosis of occupational asthma. The records are usually analysed qualitatively, and this may lead to interobserver disagreement. In this study the diagnostic value of a qualitative assessment of change in PEF was compared with objective measures of change in PEF and the results of a
