Biographical Sketch And Contributions To Medicine Of Xavier Bichat, Anne J. Krush

Transactions of the Nebraska Academy of Sciences and Affiliated Societies

Xavier Bichat was born in Thoirette, France, on 11 November 1771, the oldest son of Jean-Baptiste Bichat, a physician. As a young man, Bichat went to the city of Lyon and became the pupil of a surgeon, M.-A. Petit. In 1793, he went to the Hôtel-Dieu Hospital and studied under the surgeon, P.-J. Desault; they became close friends. Desault died at age 47 in 1795 leaving unfinished a four-volume manuscript on surgery. Faithfully, Bichat completed this work. Bichat was named Physician of Hôtel-Dieu Hospital at 1ge 28. There, he continued his research on cadavers and treatment of patients; his writing …

Some Pennsylvanian Chondrichthyan Spines From Nebraska, John G. Maisey

Transactions of the Nebraska Academy of Sciences and Affiliated Societies

Fragmentary, dermal spines of Pennsylvanian chondrichthyans from Cass and Sarpy counties, Nebraska, are described. Forms that have been identified include the genera Acondylacanthus, Amelacanthus, Bythiacanthus, and "Physonemus" and an indeterminate hybodont. A diverse chondrichthyan fauna is therefore represented by these spines. The record of Amelacanthus is the first outside Great Britain and Northern Ireland.

Collections are of state, regional, national, and international scope, with special emphasis on marine parasitology. The Laboratory is fulfilling …

Trox Hamatus Robinson (Troginae) Using A Canthon (Scarabaeinae) Brood Ball And New Records Of North American Trox (Coleoptera: Scarabaeidae), Brett C. Ratcliffe

Transactions of the Nebraska Academy of Sciences and Affiliated Societies

Trox hamatus Robinson was observed feeding on an abandoned Canthon brood ball in southeastern Nebraska. Although some Aphodiinae and Scarabaeinae have been reported feeding on or stealing other scarabaeine dung balls, this represents the first reported observation of this behavior for a member of the Troginae. It is suggested that the brood ball was opportunistically used by the Trox, and the event is rare. In addition, new state records are provided for Trox aequalis Say, T. atrox LeConte, T. laticollis LeConte, and T. tesselatus (LeConte).

American Indian Artifacts From The Kansas River, Richard A. Rogers, Larry D. Martin

Transactions of the Nebraska Academy of Sciences and Affiliated Societies

American Indian artifacts recovered from the gravel bars of the Kansas River in northeastern Kansas consist of pot sherds and projectile points. The dating of artifacts on stylistic grounds suggests a relatively continuous archeological record from the Kansas River ranging from the end of the Wisconsin glaciation to the Late Holocene. The remains of Pleistocene and Holocene fauna are abundant on the same gravel bars that yielded the artifacts. The presence of woodland musk oxen and stagmoose indicates that northeastern Kansas was part of the Symbos-Cervalces faunal province during the Wisconsinan. By inference, the Late Wisconsinan human occupants must have …

Linguistic Competence, John Tienson

Transactions of the Nebraska Academy of Sciences and Affiliated Societies

The notion of linguistic competence as a cognitive system that produces knowledge not antecedently present in the mind of the subject, e.g., knowledge of grammatical relations in response to certain stimuli is an important contribution to philosophical understanding of linguistics, and of cognitive psychology in general. This notion has not been as well received as it should have been, in part because of certain false things that have been said about it. In particular, it has been said that a grammar of a language, conceived as a theory of linguistic competence, is an idealization, and that speakers know the …

Heligmosomoides Thomomyos Sp. N. (Nematoda: Heligmosomidae) From Pocket Gophers, Thomomys Spp. (Rodentia: Geomyidae), In Oregon And California, Scott L. Gardner, Douglas Jasmer

Scott L. Gardner Publications

The nematode Heligmosomoides thomomyos sp. n. is described from the small intestine of Thomomys bulbivorus and T. bottae. This is the first report of Heligmosomoides from rodents of the family Geomyidae.

Nematodes of the genus Heligmosomoides Hall, 1916 occur most commonly in arvicolid rodents. Of the 26 known species of the genus, 11 have been recorded from Nearctic rodents (Rausch and Rausch, 1973). In North America, Heligmosomoides spp. have been recorded not only from voles, but also from cricetids and murids. Heligmosomoides spp. characteristically inhabit the small intestine or cecum of their host, where they usually are found tightly …

Cuticular Ridge Patterns Of Nematodirus (Nematoda: Trichostrongyloidea) Parasitic In Domestic Ruminants Of North America, With A Key To Species, J. R. Lichtenfels, P. A. Pilitt

Harold W. Manter Laboratory of Parasitology: Faculty and Staff Publications

The six species of Nematodirus parasitic in domestic ruminants of North America have been identified previously on the basis of characteristics of the bursa and tips of the spicules, and females could not be identified. In an effort to find additional diagnostic characteristics of both sexes, cuticular ridges were studied with light and scanning electron microscopy and in whole mounts and cross sections. After the cuticular ridges of males were characterized, females were matched with males by means of cuticular ridges, except for the rare species N. davtiani. Five of the six species have variations of an 18-ridge bilaterally …

(larvae) (ca. 2%). In addition, undeveloped cestodes of the genus Taenia in 26 animals had lost rostellar hooks and could not be identified. Host-records, prevalence, and biological characteristics of some of the helminths are …

An Rna Virus In Autographa Californica Nuclear Polyhedrosis Virus Preparations: Gross Pathology And Infectivity, P. V. Vail, Thomas Jack Morris, S. S. Collier

School of Biological Sciences: Faculty Publications

The pathology and infectivity of an RNA virus infectious to Trichoplusia ni larvae was investigated. The enzyme-linked immunosorbent assay (ELISA) and weight depression were used as criteria for virus concentration in larval homogenates and live larvae, respectively. Infected larvae were severely stunted, weighing as little as 13 times less than uninfected individuals of the same age , yet appeared normal morphologically. The virus was found to cause only slight mortality at high concentrations. Infected larvae displayed the pathological stunting response down to a dose of 0.1 ng of virus. Larvae infected with doses 100 times lower did not show the …
