Morphological and distributional changes in the eosinophilic granule cell (EGC) population of the rainbow trout (Oncorhynchus mykiss walbaum) intestine following systemic administration of capsaicin and substance P
No full textIntestinal eosinophilic granule cells (EGCs) of the rainbow trout (Oncorhynchus mykiss) have been likened to mammalian mast cells and degranulate in response to stimulation by capsaicin and substance P. This investigation was conducted to examine the effects of capsaicin and substance P on the trout intestinal EGC population and to quantify the different morphologies following systemic administration. Rainbow trout were injected intraperitoneally with capsaicin, substance P, serotonin, or vehicle controls (0.5 mug/g body weight). Fish were killed at timed intervals and the mid intestine was processed for light and electron microscopy. The number of EGCs which could be observed in the stratum compactum was quantified for each treatment over the time course of the experiment. EGCs could be classified ultrastructurally into 1 of 5 categories based on their granule morphology. The cell frequencies and relative proportion of each cell class were analyzed statistically. The frequency of EGCs in the stratum compactum of fish injected with capsaicin or substance P significantly decreased post-injection (P < 0.05) compared to controls (saline- and BSA-injected fish). Serotonin had no effect on EGC frequency, morphology, or distribution as compared with saline. Stimulation with capsaicin and substance P resulted in time-dependent changes in both EGC granule morphology and distribution within the intestinal mucosa. Following an apparent migration of EGCs to the lamina propria and degranulation, small granuled EGC-like cells appeared first in the lamina propria and then later in the stratum compactum. The significance of the stratum compactum as a depot for intestinal EGCs and the site for EGC maturation is discussed.PT: J; CR: ANDERSON C, 1983, CELL TISSUE RES, V230, P377 ANDERSON CR, 1990, CELL TISSUE RES, V259, P379 AVTALION RR, 1980, PHYLOGENY IMMUNOLOGI, P113 BEFUS AD, 1982, J IMMUNOL, V128, P2475 BERGERON T, 1982, THESIS U GUELPH CANA BERGERON T, 1983, CAN J ZOOL, V61, P133 BIENENSTOCK J, 1987, INT ARCH ALLER A IMM, V82, P238 BIENENSTOCK J, 1989, MAST CELL BASOPHIL D, P275 BJENNING C, 1988, HISTOCHEMISTRY, V88, P155 BUCK SH, 1986, PHARMACOL REV, V38, P179 DAVIDSON S, 1980, IMMUNOLOGY, V48, P439 ELLIS AE, 1977, J FISH BIOL, V11, P453 ELLIS AE, 1985, DEV COMP IMMUNOL, V9, P251 ELLIS AE, 1988, FISH VACCINATION, P32 EZEASOR DN, 1980, J FISH BIOL, V17, P619 FINN JP, 1971, J FISH BIOL, V3, P463 GLANTZ SA, 1987, PRIMER BIOSTATISTICS GULLAND GL, 1898, ANAT ANZEIGER, V14, P441 HODGINS HO, 1967, J IMMUNOL, V99, P534 HOLMGREN S, 1985, NEUROSCIENCE, V14, P683 IRANI AMA, 1989, CLIN EXP ALLERGY, V19, P143 JAMUR MC, 1988, CELL MOL BIOL, V34, P231 JOHNSON AR, 1973, P SOC EXP BIOL MED, V142, P1252 KITAZAWA T, 1989, BRIT J PHARMACOL, V98, P781 LAMAS J, 1991, FISH SHELLFISH IMMUN, V1, P187 MARZELLA L, 1987, LYSOSOMES THEIR ROLE, P319 MOUSLI M, 1989, J PHARMACOL EXP THER, V250, P329 NILSSON G, 1989, THESIS UPPSALA NILSSON G, 1990, CELL TISSUE RES, V262, P125 NOVIKOFF AB, 1976, CELL ORGANELLES, P27 PERNOW B, 1983, PHARMACOL REV, V35, P85 POWELL MD, 1990, J FISH BIOL, V37, P495 POWELL MD, 1991, CELL TISSUE RES, V266, P469 POWELL MD, 1992, AQUACULTURE, V100, P328 POWELL MD, 1992, HISTOL HISTOPATHOL, V7, P301 REIMSCHUESSEL R, 1987, J FISH DIS, V10, P319 ROBERTS RJ, 1971, J FISH BIOL, V4, P87 SHANAHAN F, 1985, J IMMUNOL, V135, P1331 SHARP GJE, 1989, J FISH BIOL, V35, P781 SMITH HE, 1975, THESIS U STIRLING ST STEAD RH, 1987, P NATL ACAD SCI USA, V84, P2975 STEAD RH, 1989, GASTROENTEROLOGY, V97, P575 SWEENEY MI, 1989, J PHARMACOL EXP THER, V248, P447 VALLEJO AN, 1989, DEV COMP IMMUNOL, V13, P133 WATSON AHD, 1979, CELL TISSUE RES, V197, P155 YASUTAKE WT, 1983, 150 US DEP INT FISH; NR: 46; TC: 10; J9: J EXP ZOOL; PG: 12; GA: LC103Source type: Electronic(1

Classification bias in commercial business lists for retail food stores in the U.S.
No full textAbstract Background Aspects of the food environment such as the availability of different types of food stores have recently emerged as key modifiable factors that may contribute to the increased prevalence of obesity. Given that many of these studies have derived their results based on secondary datasets and the relationship of food stores with individual weight outcomes has been reported to vary by store type, it is important to understand the extent to which often-used secondary data correctly classify food stores. We evaluated the classification bias of food stores in Dun & Bradstreet (D&B) and InfoUSA commercial business lists. Methods We performed a full census in 274 randomly selected census tracts in the Chicago metropolitan area and collected detailed store attributes inside stores for classification. Store attributes were compared by classification match status and store type. Systematic classification bias by census tract characteristics was assessed in multivariate regression. Results D&B had a higher classification match rate than InfoUSA for supermarkets and grocery stores, while InfoUSA was higher for convenience stores. Both lists were more likely to correctly classify large supermarkets, grocery stores, and convenience stores with more cash registers and different types of service counters (supermarkets and grocery stores only). The likelihood of a correct classification match for supermarkets and grocery stores did not vary systemically by tract characteristics whereas convenience stores were more likely to be misclassified in predominately Black tracts. Conclusion Researches can rely on classification of food stores in commercial datasets for supermarkets and grocery stores whereas classifications for convenience and specialty food stores are subject to some systematic bias by neighborhood racial/ethnic composition.</p
Nonstandard Work and Child Care Choices of Married Mothers
No full textThe focus of this paper is to examine the interplay between nonstandard employment and child care choice decisions of married mothers with young children. We draw on the 1992/93 Survey of Income and Program Participation to estimate two related econometric models of child care choice that include the choice among center, sitter, relative and parental care. First, controlling for the potential endogeneity of the nonstandard work decision, we find that being a nonstandard worker significantly reduces the likelihood of using formal modes of child care such as center and sitter care. In our second model, where we jointly estimate the work status and child care choice decisions of mothers, we find that the standard versus nonstandard work decision is more responsive to the price of child care. Finally, we conclude the paper by discussing potential policy solutions to improve the child care options for mothers with young children working in nonstandard jobs.child care, part-time, temporary, mothers, Kimmel, Powell
S12 E1: Adapting Curriculum Tasks and Materials in Mathematics to Specific Learning Goals
No full textIn today\u27s episode, Drs. Lisa Dieker and Rebecca Hines have a conversation with Sarah Powell. Sarah Powell is a Professor in the College of Education at the University of Texas at Austin and Associate Director of the Meadows Center for Preventing Educational Risk. Her research, teaching, and service focus on mathematics, particularly for students who experience mathematics differently.
Powell discussed practical tips for teaching mathematics to students with disabilities. She emphasized the importance of understanding students\u27 foundational math skills and using research-validated practices like vocabulary development and mathematical representations. Powell highlighted the need for extensive practice, suggesting that students who struggle with math may require 10 to 30 times more practice opportunities than typical students. She also mentioned the potential of AI in enhancing math education but stressed the importance of conceptual understanding. Powell concluded by reassuring new teachers that anyone can be an effective math teacher with the right knowledge and strategies.
