Breast cancer is a leading cause of cancer deaths among women, with an estimated 12.4% of American women diagnosed with this tumor type. Evidence suggests that exogenous disruptors can exert epigenetic changes leading to aberrant gene expression, shifting the cellular balance toward oncogenesis. While chemical pollutant exposure is well-studied, light...
Postmortem diagnostics play an important role in the ability to understand the cause of death of an animal. However, removal from oxygen supply, either by surgical excision or at death, leads to cell and tissue decomposition. Knowledge about factors impacting reliability of test results is extremely important for accurate diagnostics....
The echinoderm axial organ is located centrally, at the meeting point of the
animals' "circulatory" systems. This, and its unusual histology, have prompted
the implication of a number of different functions for the organ, including
circulation, excretion and host defense. None of these have been definitively
proven. Claims that starfish...
Research studies indicated that differences in cognitive
processing style influence individual behavior on various types of
tasks. This study investigated the effect of the cognitive style
dimension, field independence-dependence, on the metacognitive
functioning of individuals involved in three problem tasks which
varied in inherent structure.
Twenty-six subjects were randomly selected...
In order to investigate potential climate impacts on landscape-scale ecosystem processes, I implemented a dynamic general vegetation model (DGVM) over a large domain in northern California and western Nevada on a rectangular grid of ca. 800-meter spatial resolution. I used 100 years of observed, monthly climate and nine future climate...
Molluscan internal defenses rely heavily on circulating hemocytes. In most cases, encounters with large foreign bodies result in recognition by hemocytes followed by spreading of these defense cells over the object’s surface. The resulting encapsulation concentrates the force of the hemocytes’ assault on the foreign object.

Anecdotal accounts of tiludronate administration via intravenous regional limb
perfusion (IVRLP) exist despite a lack of information regarding safety for synovial
structures in the perfused area. The objective of this study was to determine whether
tiludronate concentrations in synovial structures after IVRLP with low dose (0.5 mg,
LDT) or high...

Resistance of the snail Biomphalaria glabrata to the trematode Schistosoma mansoni is correlated with allelic variation at copper-zinc superoxide dismutase (sod1). We tested whether there is a fitness cost associated with carrying the most resistant allele in three outbred laboratory populations of snails. These three populations were derived from the...
