Food habits and dietary variability of pelagic nekton off Oregon and Washington, 1979-1984

The food habits of 20 species of pelagic nekton were investigated from collections made with small-mesh purse seines from 1979-84 off Washington and Oregon. Four species (spiny dogfish, Squalus acanthias; soupfin shark, Galeorhinus zyopterus; blue shark, Prionace glauca; and cutthroat trout, Salmo clarki) were mainly piscivorous. Six species (coho salmon, Oncorhynchus kisutch; chinook salmon, O. tshawytscha; black rockfish, Sebastes melanops; yellowtail rockfish, S. f1avidus; sablefish, Anoplopoma fimbria; and jack mackerel, Trachurus symmetricus) consumed both nektonic and planktonic organisms. The remaining species (market squid, Loligo opalescens; American shad, Alosa sapidissima; Pacific herring, Clupea harengus pallasi; northern anchovy, Engraulis mordax; pink salmon, O. gorbuscha; surf smelt, Hypomesus pretiosus; Pacific hake, Merluccius productus; Pacific saury, Cololabis saira; Pacific mackerel, Scomber japonicus; and medusafish, Icichthys lockingtom) were primarily planktonic feeders. There were substantial interannual, seasonal, and geographic variations in the diets of several species due primarily to changes in prey availability. Juvenile salmonids were not commonly consumed by this assemblage of fishes (PDF file contains 36 pages.

Prioritization and Assessment of Educational Goals

The problem of this study was to determine the prioritization and assessment of educational goals in a selected school system. The purpose of this study was to engage citizens, administrators, teachers, and students in the prioritization and assessment of unified educational goals for public schools. The sample size for the study consisted of 117 participants in the following groups: (1) representative community group; (2) administrator group; (3) teacher group; and (4) student group. Separate meetings for each group were conducted, and each participant was asked to complete Phi Delta Kappa\u27s Individual Goal Rating Sheet and the Individual Rating of the Level of Performance of Current School Programs. Five research questions were tested to ascertain if a significant difference existed in the perceptions of community members, administrators, teachers, and students in the priority ranking and assessment ranking of 18 educational goals; to ascertain if a significant difference existed between the total mean priority ranking and the total mean assessment ranking of the educational goals; and to ascertain if a significant difference existed within the four participant groups in the priority ranking and assessment ranking of the educational goals. The Kruskal Wallis One-Way Analysis of Variance was used to test hypotheses 1 and 2. The t test for independent samples was used in testing hypothesis 3, and the Friedman Two-Way Analysis of Variance was used to test hypotheses 4 and 5. The most significant findings of this study were: A significant difference was found in the priority ranking of 11 of the 18 educational goals. The student group differed the most in assigning priorities to the goals. Community members, administrators, and teachers ranked Goal 4, Develop skills in reading, writing, speaking, and listening, as the top priority goal. Students ranked Goal 9, Develop skills to enter a specific field of work, as the top priority. A significant difference was found in the assessment ranking of 3 of the 18 goals. Again, the students differed the most from the other three groups. A significant positive t value was found in four goals, which meant that the assessment mean was lower than the priority mean. A significant difference was found within each of the participant groups regarding the priorities given to the goals. A significant difference was found within the representative community group, the administrator group, and the teacher group--but not within the student group--regarding the assessment rankings given to the 18 educational goals

Peripheral neuropathy secondary to a ‘domino’ liver transplant: a case report

Background: Peripheral neuropathy caused by amyloidosis is one of the well-recognised sequelae of mutations in the transthyretin gene (TTR).// Case presentation: We describe a case of peripheral neuropathy in a White British 74 year old man with wild-type TTR, 8 years following receipt of a ‘domino’ liver transplant (from a donor with a TTR mutation). The clinical phenotype and neurophysiology, coupled with presence of ATTR amyloid deposits on fat biopsy, established the diagnosis of ATTR amyloid neuropathy, as a consequence of receipt of a variant-TTR secreting liver. A nerve biopsy was not clinically appropriate for this patient. Such cases are rare since recipients of such livers are typically restricted to people whose natural lifespan is unlikely to stretch into the anticipated symptomatic period of ATTR amyloidosis. However, novel “gene silencing” therapeutics are now available which can dramatically alter the course of this disorder, by reducing the proportion of abnormal proteins.// Conclusions: This represents a rare but predictable iatrogenic side effect, and doctors should be aware of this eventuality occurring in a shorter time span than previously anticipated

A Note on the Fine Structure of Myoskeletal Junctions in Acartia tonsa Dana (Copepoda, Calanoida)

The endoskeleton of the calanoid copepod, Calanus finmarchicus, and its muscle attachments were described by Lowe (1935). She reported that the endoskeleton in C. finmarchicus consists of two tendinous endosternites and chitinous exoskeletal ingrowths to which muscles are attached. Howse (1960) noted attachments of the main muscles of the thorax to the exoskeleton in Acartia tonsa. Bouligand (1962) described the ultrastructure of muscle attachments to cuticle in three species of freshwater copepods of the genus Cyclops. Raymont et al. (1974) described the fine structure of muscle attachments to cuticle in C. finmarchicus. Information of the internal anatomy of marine copepods remains sparse. Therefore, we thought it worthwhile to focus our observations on the attachments of muscle to exoskeletal ingrowths in A. tonsa
