Human Cerebrovascular Endothelial Cell Responses In Severe Sepsis, Christopher J. Blom
Human Cerebrovascular Endothelial Cell Responses In Severe Sepsis, Christopher J. Blom
Electronic Thesis and Dissertation Repository
Sepsis-associated encephalopathy (SAE) is an independent predictor of mortality in severe sepsis patients. Mechanisms of SAE are poorly characterized. Pro-inflammatory mediators are up-regulated in blood plasma of severe sepsis patients and may lead to activation/dysfunction of cerebrovascular endothelial cells (CMEC) of the blood-brain barrier (BBB) – potentially contributing to brain dysfunction. The objective of the present study was to determine the effects/mechanisms of both human severe sepsis blood plasma (hSSP; 20% v/v) and a mixture of 8 cytokines/chemokines that mimicked physiological concentrations of cytokines/chemokines in hSSP (cytomix; SSCM) on human-derived CMEC (hCMEC/D3) activation/dysfunction
in vitro. hSSP-stimulation up-regulated hCMEC/D3 pro-adhesive …

The impact of synthetic amyloid β (1–42) (Aβ1–42) oligomers on biophysical properties of voltage-gated potassium channels Kv 1.3 and lipid bilayer membranes (BLMs) was quantified for protocols using hexafluoroisopropanol (HFIP) or sodium hydroxide (NaOH) as solvents prior to initiating the oligomer formation. Regardless of the solvent used Aβ1–42 samples contained oligomers that reacted with the conformation-specific antibodies A11 and OC and had similar size distributions as determined by dynamic light scattering. Patch-clamp recordings of the potassium currents showed that synthetic Aβ1–42 oligomers accelerate the activation and inactivation kinetics of Kv 1.3 current with no significant effect …

Infections remain a major cause of morbidity and mortality in transplant patients. Organ recipients are also susceptible to donor-derived pathogens and the majority of donor infections are easily treatable. Rarely, some pathogens have produced life-threatening complications by compromising the vascular anastomosis. In this case series we report loss of two kidney allografts secondary to vascular complications due to Candida albicans. Both recipients received grafts from a common donor, in whom Candida bacteremia in the donor was not apparent at the time of organ acceptance but became apparent on delayed cultures.

Since its first description in 1874 by Charcot, the hallmark feature of ALS is the progressive degeneration of upper and lower motoneurons (Charcot, 1874). In the spinal cord, motoneuron degeneration starts long before symptom onset and advances in a size-related fashion, in which large-size alpha-motoneurons degenerate first followed by small-size alpha-motoneurons (Pun et al., 2006; Hegedus et al., 2007; Hegedus et al., 2008). There are conflicting reports regarding the survival of the smallest-sized spinal motoneurons, the gamma-motoneurons (Swash and Fox, 1974; Sobue et al., 1981). Despite its original description, the neuronal degeneration in ALS is not limited to motoneurons. Recent …

The aim of this work is to propose an alternative way for wine classification and prediction based on an electronic nose (e-nose) combined with Independent Component Analysis (ICA) as a dimensionality reduction technique, Partial Least Squares (PLS) to predict sensorial descriptors and Artificial Neural Networks (ANNs) for classification purpose. A total of 26 wines from different regions, varieties and elaboration processes have been analyzed with an e-nose and tasted by a sensory panel. Successful results have been obtained in most cases for prediction and classification.
Physiological And Toxicological Roles Of Abc Transporters In Cellular Efflux Of Substrates, Donna J. Coy
Physiological And Toxicological Roles Of Abc Transporters In Cellular Efflux Of Substrates, Donna J. Coy
Theses and Dissertations--Toxicology and Cancer Biology
ATP-binding cassette (ABC) transporters are transmembrane proteins that transport a wide variety of substrates across intra and extra-cellular membranes. A few examples of endo and xenobiotic substrates are metabolic products, lipids, sterols, and drugs. An important function of ABC transporters involved in export is to prevent intracellular the buildup of toxic products. Several ABC transporters have also been associated with drug resistance upon treatment with chemotherapeutic agents. P-glycoprotein (P-GP) and the multidrug resistant (MRP) transporters of the ABC C family are examples of transporters that confer chemo-resistance.
We have studied two unique roles of ABC transporters in the liver and …
Heart Rate And Accelerometry During Singles Footbag Net Play, Christopher Michael Siebert
Heart Rate And Accelerometry During Singles Footbag Net Play, Christopher Michael Siebert
Dissertations and Theses
This investigation examined the heart rate responses and movement characteristics of experienced footbag net players during singles play. Footbag net is a net/court sport similar to volleyball, but it is played with a footbag (e.g., Hacky-SackTM) using only the feet. In singles footbag net, players are allowed either one or two kicks to propel the footbag over the net. Subjects were 15 males and 1 female, ranging in age from 18- 60 years, with a mean age of 33.6 years. Subjects played two games of singles footbag net using two different scoring systems: "sideout" scoring and "rally" scoring. …
Is Laughter The Best Medicine? An Evaluation Of The Physiological Effects Of Laughter, Annette Dalezman
Is Laughter The Best Medicine? An Evaluation Of The Physiological Effects Of Laughter, Annette Dalezman
The Science Journal of the Lander College of Arts and Sciences
Laughter directly affects one’s physiology. Laughter causes various muscle contractions which, in turn, affect body systems. Specifically, the cardiovascular, immune, and respiratory systems are impacted by laughter. Stress levels and pain tolerance thresholds are also directly impacted by laughter. Research has been done on the effects of laughter in patients with cancer, dementia, and atopic dermatitis. Based on the review of multiple experiments, a direct correlation between laughter and multiple body systems and diseases seems to exist.
Selective Breeding For 50 Khz Ultrasonic Vocalization Emission Produces, Howard Cromwell
Selective Breeding For 50 Khz Ultrasonic Vocalization Emission Produces, Howard Cromwell
Howard Casey Cromwell
Ultrasonic vocalizations (USVs) are emitted by rodents and can signal either negative or positive affective states in social and nonsocial contexts. Our recent work has utilized selective breeding based upon the emission of 50 kHz USVs in response to standard cross species hand play—namely experimenters ‘tickling’ rats. Previous work has shown that high-tickle responsive animals (i.e., rats emitting abundant 50 kHz USVs) are gregarious and express enhanced positive emotional behaviors relative to animals exhibiting low 50 kHz USVs. The present study extends this work by examining the developmental profile of play behavior and the suppression of play behavior by predator …
