RESUMO

Progress in genetics and evolutionary biology in the young Union of Soviet Socialist Republics (USSR) was hindered in the 1930s by the agronomist Trofim Lysenko, who believed that acquired traits are inherited, claimed that heredity can be changed by "educating" plants, and denied the existence of genes. Lysenko was supported by Communist Party elites. Lysenko termed his set of ideas and agricultural techniques "Michurinism," after the name of the plant breeder Ivan Michurin, but they are currently known as Lysenkoism. Although Michurinism opposed biological science, Lysenko took up one academic position after another. In 1929, Nikolai Vavilov founded the Lenin All-Union Academy of Agricultural Sciences and became its head; it directed the development of sciences underpinning plant and animal breeding in the Soviet Union. Vavilov was dismissed in 1935 and later died in prison, while Lysenko occupied his position. The triumph of Lysenkoism became complete and genetics was fully defeated in August 1948 at a session of the academy headed by Lysenko. The session was personally directed by Joseph Stalin and marked the USSR's commitment to developing a national science, separated from the global scientific community. As a result, substantial losses occurred in Soviet agriculture, genetics, evolutionary theory, and molecular biology, and the transmission of scientific values and traditions between generations was interrupted. This article reviews the ideological, political, economic, social, cultural, personal, moral, and ethical factors that influenced the August 1948 session, and its immediate and later consequences. We also outline current attempts to revise the role of the August session and whitewash Lysenko.

RESUMO

OBJECTIVE: To use the rs1229984 variant in the alcohol dehydrogenase 1B gene (ADH1B) as an instrument to investigate the causal role of alcohol in cardiovascular disease. DESIGN: Mendelian randomisation meta-analysis of 56 epidemiological studies. PARTICIPANTS: 261 991 individuals of European descent, including 20 259 coronary heart disease cases and 10 164 stroke events. Data were available on ADH1B rs1229984 variant, alcohol phenotypes, and cardiovascular biomarkers. MAIN OUTCOME MEASURES: Odds ratio for coronary heart disease and stroke associated with the ADH1B variant in all individuals and by categories of alcohol consumption. RESULTS: Carriers of the A-allele of ADH1B rs1229984 consumed 17.2% fewer units of alcohol per week (95% confidence interval 15.6% to 18.9%), had a lower prevalence of binge drinking (odds ratio 0.78 (95% CI 0.73 to 0.84)), and had higher abstention (odds ratio 1.27 (1.21 to 1.34)) than non-carriers. Rs1229984 A-allele carriers had lower systolic blood pressure (-0.88 (-1.19 to -0.56) mm Hg), interleukin-6 levels (-5.2% (-7.8 to -2.4%)), waist circumference (-0.3 (-0.6 to -0.1) cm), and body mass index (-0.17 (-0.24 to -0.10) kg/m(2)). Rs1229984 A-allele carriers had lower odds of coronary heart disease (odds ratio 0.90 (0.84 to 0.96)). The protective association of the ADH1B rs1229984 A-allele variant remained the same across all categories of alcohol consumption (P=0.83 for heterogeneity). Although no association of rs1229984 was identified with the combined subtypes of stroke, carriers of the A-allele had lower odds of ischaemic stroke (odds ratio 0.83 (0.72 to 0.95)). CONCLUSIONS: Individuals with a genetic variant associated with non-drinking and lower alcohol consumption had a more favourable cardiovascular profile and a reduced risk of coronary heart disease than those without the genetic variant. This suggests that reduction of alcohol consumption, even for light to moderate drinkers, is beneficial for cardiovascular health.

RESUMO

Allele frequencies for 15 STRs (CSF1PO, D3S1358, D5S818, D7S820, D8S1179, D13S317, D16S539, D18S51, D21S11, FGA, Penta D, Penta E, THO1, TPOX, and vWA) in the PowerPlex 16 System (Promega Corporation) were assessed in 386 individuals from five Russian urban populations. No significant between-population differences in frequencies and molecular variance of 15 microsatellites were revealed. For all 15 loci, the combined matching probability is 3.19 x 10(-18) and the power of exclusion is 99.99989%.
