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 ...
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 ...
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 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 ...
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 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 ...
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 ...
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 ...
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 ...
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 ...
