Trends in cancer mortality in Switzerland, 1951-1984.

Trends in overall age-standardized, truncated (35-64 years) and age-specific (40 to 49) cancer death certification rates in Switzerland from 1951 to 1984 were analysed. There was a substantial rise in lung cancer mortality in males, with an over 100% increase in overall rates. Thus, in the early 1980's, lung cancer alone accounted for 26% of all cancer deaths in Swiss males. However, male lung cancer rates tended to level off in subsequent cohorts starting from younger middle age in the late 1960's. In females, lung cancer mortality was approximately ten times lower than in males, but rates had been consistently rising since the late 1960's in all age groups. Declines were observed for several neoplasms of the digestive tract: besides stomach (overall decline 68% in males, 77% in females), trends were markedly downwards also for oesophageal cancer in males (-57%), and there was some moderate fall for intestinal sites in both sexes and gallbladder in females. Several trends for other common neoplasms were similar to those observed in other developed countries, such as the declines for (cervix) uteri, the general stability for breast cancer, or the increases in pancreatic cancer and (melanoma) of the skin. A peculiar feature of Swiss data, besides the marked decline in oesophageal cancer in males, was the consistent downward trend in thyroid cancer for both sexes. Thus, overall age-standardized total cancer mortality over the last three decades was moderately upwards in Swiss males, but consistently downwards in females. Male trends were more reassuring in middle age, chiefly in consequence of the flattening in lung cancer rises. Possible interpretations of these trends in terms of aetiological hypotheses (i.e., changes in alcohol drinking and improvements in diet for oesophageal cancer, or reduced prevalence of iodine deficiency for thyroid neoplasms) are discussed.

Efeito do retardamento da secagem na qualidade fisiológica de sementes armazenadas de azevém anual

O objetivo deste trabalho foi avaliar os efeitos do retardamento da secagem e do armazenamento aberto na qualidade fisiológica de sementes de azevém anual (Lolium multiflorum Lam.), cultivar Comum-RS. Compararam-se períodos de retardamento da secagem (0, 2, 4, 6, 8, 12, 18, 24, 36 e 48 horas) e períodos de armazenamento (0, 4 e 8 meses). Enquanto submetidas aos períodos de retardamento da secagem, 24 kg de sementes ficaram acondicionadas em 18 caixas de poliestireno. A secagem foi realizada sobre piso de concreto, à sombra, por 12 horas, sendo completada em estufa a 35ºC com circulação forçada de ar. As sementes mantiveram o nível inicial de germinação durante os oito meses de armazenamento, mesmo com até 12 horas de retardamento da secagem; entretanto, com seis horas de retardamento, o vigor das sementes foi reduzido aos oito meses de armazenamento, mas se manteve praticamente inalterado aos quatro meses, com até 11 horas de retardamento. Sementes com germinação acima de 70% mantiveram este valor até oito meses de armazenamento, independentemente do período de retardamento da secagem.

Ganho genético decorrente da substituição anual de cultivares de milho

Cultivares de milho (Zea mays) são normalmente substituídas alguns anos após a indicação para cultivo. Os objetivos deste trabalho foram desenvolver e avaliar um teste de hipótese para determinar se as substituições anuais de cultivares, nos ensaios de competição de cultivares indicadas de milho, resultam em ganho genético para produtividade de grãos. Os ensaios de competição de cultivares de milho superprecoce, precoce e normal foram conduzidos nos anos agrícolas de 1998/1999, 1999/2000, 2000/2001 e 2001/2002. O delineamento experimental foi em blocos ao acaso, com três repetições. Cada parcela foi formada por duas fileiras de 5 m de comprimento, com espaçamento de 0,8 m. O ganho genético, quanto à produtividade de grãos, foi estimado pelo método proposto por Vencovsky et al., e a significância verificada pelo teste de hipótese proposto neste trabalho. As substituições anuais de cultivares de milho são dinâmicas e nem sempre resultam em ganho genético para produtividade de grãos.

Totes les vacances són diferents. És més beneficiós fer el descans anual sempre a la mateixa època i recordar-lo

Les vacances, el descans mensual, ens influeixen des del punt de vista psicològic i fisiològic, en vista de dos treballs científics recents que analitzen minuciosament els seus efectes.
