The ability of cells to respond to external mechanical stimulation is a complex and robust process involving a diversity of molecular interactions. Although mechanotransduction has been heavily studied, many questions remain regarding the link between physical stimulation and biochemical response. Of significant interest has been the contribution of the transmembrane proteins involved, and integrins in particular, because of their connectivity to both the extracellular matrix and the cytoskeleton. Here, we demonstrate the existence of a mechanically based initiation molecule, syndecan-4. We first demonstrate the ability of syndecan-4 molecules to support cell attachment and spreading without the direct extracellular binding of …

A K2a-Positive Klebsiella Pneumoniae Causes Liver And Brain Abscess In A Saint Kitt’S Man, Melissa S. Doud, Reni Grimes-Zeppegno, Enrique Molina, Nancimae Miller, Danajeyan Balachandar, Lisa Schneper, Robert Poppiti, Kalai Mathee

Department of Biological Sciences

Klebsiella pneumoniae isolated in community-acquired pneumonia is increasingly found in primary pyogenic liver abscesses. The presence of magA in K. pneumoniae has been implicated in hypermucoviscosity and virulence of liver abscess isolates. The K2 serotype has also been strongly associated with hypervirulence. We report the isolation of non-magA, K2 K. pneumoniae strain from a liver abscess of a Saint Kitt’s man who survived the invasive syndrome.

Effects Of Estrogen On Muscle Damage In Response To An Acute Resistance Exercise Protocol, Megan R. Wolf

Honors Scholar Theses

Creatine Kinase (CK) is used as a measure of exercise-induced muscle membrane damage. During acute eccentric (muscle lengthening) exercise, muscle sarcolemma, sarcoplasmic reticulum, and Z-lines are damaged, thus causing muscle proteins and enzymes to leak into the interstitial fluid.

Strenuous eccentric exercise produces an elevation of oxygen free radicals, which further increases muscle damage. Muscle soreness and fatigue can be attributed to this membrane damage. Estradiol, however, may preserve membrane stability post-exercise (Brancaccio, Maffulli, & Limongelli, 2007; Carter, Dobridge, & Hackney, 2001; Tiidus, 2001). Because estradiol has a similar structure to Vitamin E, which is known to have antioxidant properties, …

Accumulation Of Rhodopsin In Late Endosomes Triggers Photoreceptor Cell Degeneration, Yashodhan Chinchore, Amitavo Mitra, Patrick J. Dolph, Norbert Perrimon

Dartmouth Scholarship

Progressive retinal degeneration is the underlying feature of many human retinal dystrophies. Previous work using Drosophila as a model system and analysis of specific mutations in human rhodopsin have uncovered a connection between rhodopsin endocytosis and retinal degeneration. In these mutants, rhodopsin and its regulatory protein arrestin form stable complexes, and endocytosis of these complexes causes photoreceptor cell death. In this study we show that the internalized rhodopsin is not degraded in the lysosome but instead accumulates in the late endosomes. Using mutants that are defective in late endosome to lysosome trafficking, we were able to show that rhodopsin accumulates …

A New Laser Pointer Driven Optical Microheater For Precise Local Heat Shock, Mike Placinta

Masters Theses 1911 - February 2014

The zebrafish has emerged as an important genetic model system for the study of vertebrate development. However, while genetics is a powerful tool for the study of early gene functions, the approach is more limited when it comes to understanding later functions of genes that have essential roles in early embryogenesis. There is thus a need to manipulate gene expression at different times, and ideally only in some regions of the developing embryo. Methods for conditional gene regulation have been established in Drosophila, C.elegans and the mouse, utilizing conditional gene activation systems such as the Gal4-UAS system (fly) and the …

A Watershed Analysis Of Salmon Lake And Mcgrath Pond: Implications For Water Quality And Land Use Management, Colby Environmental Assessment Team, Colby College, Problems In Environmental Science Course (Biology 493), Colby College

Colby College Watershed Study: Salmon Lake and McGrath Pond (2009, 1993)

In the summer and fall of 2009, the Colby Environmental Assessment Team (CEAT) studied the water quality of Salmon Lake and McGrath Pond, located in the Belgrade Lakes Region of Maine. The physical, chemical and biological characteristics of water quality were measured and analyzed to evaluate the current health of these lakes. Water quality data collected during the summer and fall of 2009 were compared with data from previous years to study the historic water quality trends. Land use patterns in the Salmon/McGrath watershed were also examined to investigate their impact on the lake water quality. The water quality trends …

Habitat Variation Among Aquatic Gastropod Assemblages Of Indiana, U.S.A., Mark Pyron, Jayson Beugly, Matthew Spielman, Jennifer Pritchett, Stephen J. Jacquemin

Biological Sciences Faculty Publications

We collected aquatic gastropods at 137 sites in lakes and streams of Indiana and tested for patterns of assemblages with environmental variables. The survey resulted in 32 species with a mean of 2.8 species at each site, and a mean abundance at each site of 144 individuals. Nonmetric multidimensional scaling (NMS) multivariate analyses resulted in watershed drainage area, water conductivity, substrate category frequency, and dissolved oxygen as significant correlates of gastropod assemblage structure. Gastropod assemblages of lakes were not significantly different than assemblages of streams in the ordination. Prosobranch taxa occurred in higher abundances than pulmonate taxa at sites with …

A Discourse On The Public Nature Of Research In Contemporary Life Science: A Law-Policy Proposal To Promote The Public Nature Of Science In An Era Of Academia-Industry Integration, Michael J. Malinowski

Journal Articles

This article addresses the impact of integration of academia, industry, and government on the public nature of research. The article concludes that, while the integration has benefited science immensely, regulatory measures should be taken to restore the public nature of research in an age of integration.
