The Flora of Iowa - A Progress Report Based on Past Contributions

All one of the basic preliminaries in a plan for the ultimate preparation of a flora of Iowa, a survey of Iowa botanical literature has been undertaken in an attempt to assay the status of our knowledge of the state flora. Three aspects of this knowledge were kept in mind during the literature search: (a) general, regional and county floras, (b) the comparison of areas, and (c) taxonomic treatments of specific families and genera of plants. Only the ferns and the flowering plants were included in this literature survey, the mosses and liverworts having been recently summarized by Conard (1945a, 1945b) and the algae and fungi being considered as beyond the scope of this particular study. To obtain the data presented in the present paper, individual volumes of certain periodicals were examined for papers dealing with Iowa plants, a few unpublished theses in the Iowa State College library were consulted, and complete sets of the following publications were examined

A Comparison of the Forest Floras along the Des Moines and Missouri Rivers

A cursory examination of the deciduous forest of eastern North America, at intervals from its center (14) in the Ohio River basin westward, discloses changes in the structure of the forest characterized chiefly by a reduction in number of species and in the abundance and size of the component trees. Beyond the Mississippi river in Iowa and eastern Nebraska the forest flora is concentrated chiefly along streams flowing diagonally southeastward. Bordering these streams the deciduous forest extends into the prairie

A Preliminary Report on Biosystematic Studies of Iowa Smartweeds (Polygonum Spp.)

The senior author first developed an interest in the smartweeds (Polygonum spp.) in connection with studies and survey work on the European corn borer (Pyrausta nubilalis Hubn.) and related borers. These are Pyrausta ainsliei Hein, the smartweed borer, and P. penitalis Grote, the lotus borer; both are native to North America, while P. nubilalis was introduced into this country from Europe and has become a serious pest of corn. This insect was first noticed in the United States in 1917 in the New England states. It gradually spread westward and was first reported in Iowa in 1943 from Clinton County. By last year (1947) it had spread throughout the state arid into eastern Nebraska

Compilation Contexts of Medieval and Early Modern Bulgarian Charms

The article deals with the medieval and early modern Bulgarian verbal charms and their textual contexts. More specifically, the focus is on the manuscripts in which these charms can be found. Both the charms and the manuscripts are discussed as cultural phenomena, which were part of complex cultural contexts, including processes like compilation, usage, adaptation and transmission. The article traces the organising principles of the miscellanies containing verbal magic, and also the actors and factors that influence these manuscripts and their content. Then, the article discusses the specifics and the role of variation and practicality, and the complex interrelation between the written and the oral. Finally, the article points out some specific patterns and relations between the apotropaic and curative functions of the charms, the processes of written and oral transmission, and the broader textual content of the manuscripts. The main goal of the paper is to urge a discussion on medieval and early modern Bulgarian verbal charms in the light of their immediate textual and broader cultural environment

Extensive identification of genes involved in congenital and structural heart disorders and cardiomyopathy

Clinical presentation of congenital heart disease is heterogeneous, making identification of the disease-causing genes and their genetic pathways and mechanisms of action challenging. By using in vivo electrocardiography, transthoracic echocardiography and microcomputed tomography imaging to screen 3,894 single-gene-null mouse lines for structural and functional cardiac abnormalities, here we identify 705 lines with cardiac arrhythmia, myocardial hypertrophy and/or ventricular dilation. Among these 705 genes, 486 have not been previously associated with cardiac dysfunction in humans, and some of them represent variants of unknown relevance (VUR). Mice with mutations in Casz1, Dnajc18, Pde4dip, Rnf38 or Tmem161b genes show developmental cardiac structural abnormalities, with their human orthologs being categorized as VUR. Using UK Biobank data, we validate the importance of the DNAJC18 gene for cardiac homeostasis by showing that its loss of function is associated with altered left ventricular systolic function. Our results identify hundreds of previously unappreciated genes with potential function in congenital heart disease and suggest causal function of five VUR in congenital heart disease
