Upregulation Of Defensins In Burn Sheep Small Intestine, Brian J Poindexter, Gordon L Klein, Stephen M Milner, Roger J Bick

Faculty, Staff and Student Publications

OBJECTIVE: The aim of this study was to visualize and localize the sheep antimicrobials, beta-defensins 1, 2, and 3, (SBD-1, SBD-2, SBD-3), sheep neutrophil defensin alpha (SNP-1), and the cathelicidin LL-37 in sheep small intestine after burn injury, our hypothesis being that these compounds would be upregulated in an effort to overcome a compromised endothelial lining. Response to burn injury includes the release of proinflammatory cytokines and systemic immune suppression that, if untreated, can progress to multiple organ failure and death, so protective mechanisms have to be initiated and implemented.

METHODS: Tissue sections were probed with antibodies to the antimicrobials …

Structure Altering Effects Of A Multicomponent Reading Intervention: An Application Of The Direct And Inferential Mediation (Dime) Model Of Reading Comprehension In Upper Elementary Grades, Georgios Kalantzis, Harel Z Shouval

Faculty, Staff and Student Publications

BACKGROUND: Synaptic plasticity underlies many aspect of learning memory and development. The properties of synaptic plasticity can change as a function of previous plasticity and previous activation of synapses, a phenomenon called metaplasticity. Synaptic plasticity not only changes the functional connectivity between neurons but in some cases produces a structural change in synaptic spines; a change thought to form a basis for this observed plasticity. Here we examine to what extent structural plasticity of spines can be a cause for metaplasticity. This study is motivated by the observation that structural changes in spines are likely to affect the calcium dynamics …

Molluscan Memory Of Injury: Evolutionary Insights Into Chronic Pain And Neurological Disorders, Edgar T Walters, Leonid L Moroz

Faculty, Staff and Student Publications

Molluscan preparations have yielded seminal discoveries in neuroscience, but the experimental advantages of this group have not, until now, been complemented by adequate molecular or genomic information for comparisons to genetically defined model organisms in other phyla. The recent sequencing of the transcriptome and genome of Aplysia californica, however, will enable extensive comparative studies at the molecular level. Among other benefits, this will bring the power of individually identifiable and manipulable neurons to bear upon questions of cellular function for evolutionarily conserved genes associated with clinically important neural dysfunction. Because of the slower rate of gene evolution in this molluscan …

Is Paromomycin An Effective And Safe Treatment Against Cutaneous Leishmaniasis? A Meta-Analysis Of 14 Randomized Controlled Trials, Dae Hyun Kim, Hye Jin Chung, Joachim Bleys, Reza F Ghohestani

Faculty, Staff and Student Publications

BACKGROUND: High cost, poor compliance, and systemic toxicity have limited the use of pentavalent antimony compounds (SbV), the treatment of choice for cutaneous leishmaniasis (CL). Paromomycin (PR) has been developed as an alternative to SbV, but existing data are conflicting.

METHODOLOGY/PRINCIPAL FINDINGS: We searched PubMed, Scopus, and Cochrane Central Register of Controlled Trials, without language restriction, through August 2007, to identify randomized controlled trials that compared the efficacy or safety between PR and placebo or SbV. Primary outcome was clinical cure, defined as complete healing, disappearance, or reepithelialization of all lesions. Data were extracted independently by two investigators, and pooled …
