Activation and suppression of macrophages: implications for cancer immunotherapy
(2006)It is widely known that macrophages can be activated to kill tumor cells. It is also known that tumor-infiltrating macrophages can be immunosuppressed. The mechanisms of both tumor killing by activated macrophages and ... -
Submerged macrophytes in Big Spring Creek, WI: Distribution and influence on phosphorus dynamics
(2007)Submerged macrophytes affect many aspects of lotic ecosystems, including nutrient dynamics. We performed longitudinal vegetation surveys to describe the distribution of macrophytes in Big Spring Creek, Wisconsin. We also ... -
Determining the impacts of residential lakeshore development and various physical factors on largemouth bass (Micropterus salmoides) growth rates
(2007)Development of residential lakeshore properties can have several effects on aquatic ecosystems including the thinning of littoral coarse woody habitat. Previous studies have shown that reduction of littoral coarse woody ... -
The effects of 1,25 D3 on the mouse osteopontin promoter
(2007)Vitamin D (1,25 D3) is an important transcriptional regulator of many genes including our gene of interest, osteopontin. Osteopontin is a known regulator of bone calcification and mineralization and is involved in signaling ... -
Reduction of androgen induced reactive oxygen species (ROS) production as a method of preventing prostate cancer
(2007)Prostate cancer is a leading cause of cancer deaths among men and development of a preventative agent is urgently needed. Reactive oxygen species (ROS) are carcinogens and are linked to prostate tumor development. ROS ... -
Delta-opioid receptor (DOR) activation prolongs respiratory motor output during oxygen-glucose deprivation (OGD) in neonatal rat spinal cord in vitro
(2007)Severe reduction of blood flow to the brain results in oxygen-glucose deprivation (OGD) and neuronal damage. DOR activation is neuroprotective during OGD in the cerebellum and cortex, but it is not known whether DOR ... -
Present management practices and future possibilities for the Concha Prieta (Anadara tuberculosa) in the community of San Felipe, Ecuador
(2007)San Felipe is a small fishing village on the Caraquez estuary on the coast of Ecuador. Only twenty years ago, this community was able to sustain itself on clam collecting, but due to poor management and mangrove destruction, ... -
E. coli contaminated drinking water in rural Uganda: Using results to make an impact
(2007)In January 2006, I worked with Community Based Integrated Nutrition (COBIN) to perform water quality testing and design & distribute health questionnaires to 40 households in the Lyantonde and Kiruhura districts of rural ... -
Studies on the heat stability of egg yolk antibody (lgY)
(2007)Nutritionally and economically-important heat-labile proteins, including enzymes, hormones, and antibodies (Ab), lose a substantial amount of activity following industrial processing. Protection of these heat-sensitive ... -
Utilizing oscillating magnetic fields to manipulate embryonic tissues
(2007)Embryonic mouse tissues were incubated with gold-coated iron conjugated to a p75 antibody and then exposed to an oscillating magnetic field (OM). The p75 antibodies tag neural crest-derived cells, and via this interaction ... -
Gaze-evoked blinks in rhesus monkeys
(2007)Gaze-evoked blinks, blinks that occur during rapid movements of the head and eyes, are believed to be the result of a shared mechanism that is responsible for a blink occurring with a saccade. In humans, it has been found ... -
Comparison of non-heme liver iron and iron metabolism protein levels in superoxide dismutase 1 knock-out mice versus superoxide dismutase 1 wild-type mice
(2007)Iron is an important micronutrient that is necessary for multiple cellular functions. However, iron levels must be tightly regulated in order to prevent iron-deficiency and iron-toxicity. There are many proteins involved ... -
Inhibition of the Escherichia coli replication cycle by a mutant RecA protein
(2008)Abstract: A conserved [K/R]x[K/R] motif is found at the subunit-subunit interface in bacterial RecA protein filaments. In the Escherichia coli RecA protein, this motif is made up of residues K248 and K250. Both of these ... -
The Role of PGC-1alpha in Adipocyte Differentiation and Fat Mobilization
(2008)Calorie Restriction (CR) without malnutrition extends mean and maximal lifespan in multiple species, although the mechanism is unknown. CR has a dramatic effect on adipose tissue morphology, gene expression and energy ... -
The Biochemical Characterization of a Translational Repressor
(2008)Iron regulatory proteins (IRP) are crucial post-transcriptional regulators of iron metabolism. They influence the synthesis of proteins involved in iron uptake, storage and use by binding to their mRNAs. IRP1 stands out ... -
The role of offspring in mitigating extreme stress in lactating female mice
(2009)Mothers of many species find great comfort in their offspring, which in turn has been found to alleviate mild stress in the mother. In the face of a life-threatening event, however, do offspring still act as effective ... -
Neuronal lysosome permeabilization dynamics in ischemia
(2009)The mechanism in which lysosomes are damaged by free radicals during neuronal ischemia is examined in rat hippocampus. There are two hypotheses. The free radicals can degrade the lysosome membrane through liquefaction; all ... -
TRPV1 mediates matrix metalloproteinase expression in spinal cord injury-induced chronic neuropathic pain
(2009)Neuropathic pain (NP) is common following spinal cord injury (SCI). Evidence exists for the involvement of many processes in NP development following SCI (Cain et al, 2007). Our past studies identified increased expression ... -
Matching between dietary preferences and digestive capacity in passerine birds
(2009)It has been argued that evolutionary shifts in diet preferences are paired with changes in digestive physiology, including digestive enzyme activities. For example, a previous study in birds (Martinez del Rio 1990) found ... -
LEF/TCF family transcription factors are important in the upregulation and restricted expression of zic genes in the dorsal neural tube
(2009)A central question in biology is how different cell-types arise from an initially one-celled embryo to form an organism. Many cellular differences arise through differential gene expression in space and time via the action ...
