Carcinoma of the head of the pancreas: evaluation of the pancreaticoduodenal veins with dynamic CT--potential for improved accuracy in staging.
Although dilatation of these small peripancreatic veins without other CT criteria of tumor unresectability is an unusual finding, it may be a reliable sign of unresectable pancreatic carcinoma.
Venous anatomy of the pancreatic head: normal CT appearance in cadavers and patients.
The anterior and posterior superior pancreaticoduodenal veins and gastrocolic trunk are routinely visualized on CT scans of patients without pancreatic disease and assessment of the veins may be useful in staging pancreatic carcinoma.
Moths trapped in Alaska with feeding attractant lures and the seasonal flight patterns of potential agricultural pests
Traps baited with two types of chemical feeding attractants yielded 97 species of macrolepidoptera at three areas in Alaska, including 16 geometrid, 1 thyatirid, and 76 noctuid moth species and 4 species of nymphalid butterflies.

Several taxonomic issues in the moth families Erebidae and Noctuidae are addressed for Northwestern North America and the following new synonyms are proposed: Chytolita petrealis Grote with Herminea morbidalis Guenée and Gortyna columbia Barnes & Benjamin.
Water catalysis of peptide hydrogen isotope exchange.
The temperature dependence of the hydrogen-tritium and deuterium-hydrogen exchange reactions in poly(DL-alanine) has been reexamined. The results indicate a significant contribution to the observed…
A Diversity of Moths (Lepidoptera) Trapped with Two Feeding Attractants
Both of these lures hold advantages for trapping different types of moths, and both lures might be used in a complementary way to sample moth biodiversity.

The highly variable phenological responses to climate change in Pacific Northwest moths agree with other studies on Lepidoptera and suggest that it will remain difficult to accurately forecast which species and ecological interactions are most likely to be affected by climate change.
Revision of the genus Aseptis McDunnough (Lepidoptera, Noctuidae, Noctuinae, Xylenini) with a description of two new genera, Paraseptis and Viridiseptis
DNA sequence data for the 658-base pair “barcode” segment of the mitochondrial gene for subunit 1 of cytochrome c oxidase was used as a secondary support for taxonomic changes within Aseptis and for the two new genera.
A Revision of Lasionycta Aurivillius (Lepidoptera: Noctuidae) for North America and notes on Eurasian species, with descriptions of 17 new species, 6 new subspecies, a new genus, and two new species…
Th e North American species of Lasionycta Aurivillius are revised to include 43 species and 13 subspecies using traditional methods and mitochondrial cytochrome oxidase subunit 1 (CO1) DNA sequence…
