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 …
Cosmic Ray Particles Images With Orca-Ii Erg, George Mcnamara
Cosmic Ray Particles Images With Orca-Ii Erg, George Mcnamara
George McNamara
Cosmic ray particles image series acquired using a Hamamatsu ORCA-II ERG scientific grade CCD camera, cooled to -60 C. Each image is a consecutive 600 second (10 minute) exposure time with no light to the camera.
While processing the data, I discoverd that the background changed around planes 25 and 227 (see Excel file and jpeg screenshots), so I also processed only planes 025-227 (203 planes total, 2030 minutes, 33.83 hours). the CCD industry "rule of thumb" for a "typical" CCD sensor (i.e. 1/3" CCD) is that one cosmic ray particle strikes a sensor approximately every 30 seconds (assuming not …
Exercise-Induced Neuroprotection In A Hemiparkinsonian 6-Hydroxydopamine Rat Model, Merrill Russen Landers
Exercise-Induced Neuroprotection In A Hemiparkinsonian 6-Hydroxydopamine Rat Model, Merrill Russen Landers
UNLV Theses, Dissertations, Professional Papers, and Capstones
Outside of finding a cure, one of the preeminent goals of research in Parkinson's disease (PD) is finding a neuroprotective treatment that when applied prior to the onset of the disease will decrease the risk and severity of the subsequent disease. One such treatment that has potential as a neuroprotective agent in PD is exercise. Several studies have found forced exercise to be protective of Parkinson's disease in adult rodent models; however, few of these studies have used a design wherein voluntary exercise was evaluated. Moreover, no study has used a true neuroprotective design in which exercise was applied prior …
Teaching Stress Physiology Using Zebrafish (Danio Rerio), Michael Cooper, Shree Dhawale, Ahmed Mustafa
Teaching Stress Physiology Using Zebrafish (Danio Rerio), Michael Cooper, Shree Dhawale, Ahmed Mustafa
Ahmed Mustafa Dr.
A straightforward and inexpensive laboratory experiment is presented that investigates the physiological stress response of zebrafish after a 5 °C increase in water temperature. This experiment is designed for an undergraduate physiology lab and allows students to learn the scientific method and relevant laboratory techniques without causing significant stress to animals. An additional experimental design and a set of additional questions for lab report are also included.

Introduction To Nanoscopy Nano-Talk, George Mcnamara
Introduction To Nanoscopy Nano-Talk, George Mcnamara
George McNamara
T7-1 is the designation for the LMRG Nanoscopy session at ABRF in Orlando, FL, on March 20, 2012. The PDF file here is a draft of my presentation.
May not be very helpful since (1) would probably help to know what is in my head and each slide will [hopefully] prompt me to say, and (2) 10 minute talk so I am going to push the "next slide" button after saying very little.

Pubspectra - Open Data Access Fluorescence Spectra, George Mcnamara
Pubspectra - Open Data Access Fluorescence Spectra, George Mcnamara
George McNamara
The Internet is enabling greater access to spectral imaging publications, spectral graphs, and data than that was available a generation ago. The spectral imaging systems discussed in this issue of Cytometry work because reagent and hardware spectra are reproducible, reusable, and provide input to spectral unmixing and spectral components recognition algorithms. These spectra need to be readily available in order to determine what to purchase, how to use it, and what the output means. We refer to several commercially sponsored and academic spectral web sites and discuss our spectral graphing and data sites. Sites include fluorescent dye graph servers from …

The Effects Of Oxygen On The Electrophysiology Of Co2/H+-Chemosensitive And -Insensitive Neurons Of The Solitary Complex Of The Rat, Michael Patrick Matott
The Effects Of Oxygen On The Electrophysiology Of Co2/H+-Chemosensitive And -Insensitive Neurons Of The Solitary Complex Of The Rat, Michael Patrick Matott
USF Tampa Graduate Theses and Dissertations
This study tested the hypothesis that decreasing the control O2 level from 95% to 40% (5% CO2 + 55% N2) maintains viability in caudal solitary complex (cSC) neurons in transverse slices (~300-400ꝳ) prepared from neonatal rat (P2-22) maintained at 32-34°C. The underlying rationale is to reduce exposure to redox and nitrosative stimuli generated during several hours of exposure to 95% O2 that produces a tissue O2 tension throughout the slice which is in excess of 203 kPa (2.0 atmospheres absolute,ATA) oxygen. Whole cell recordings of cSC neurons maintained in 40% O2 exhibited spontaneous …

A Proposal To Test The Effects Of Factor Ecat1 On Pluripotency, From Reprogramming To Differentiation Of Human Somatic Cells, Vritti R. Goel
CMC Senior Theses
The field of stem cell research has been growing more because of the interest in using stem cells to cure diseases and heal injuries. Human embryonic stem cells, because of the controversy surrounding them—and subsequently the difficulties in acquiring samples of the existing aging cell lines—can only be used in limited capacities. While the development of induced pluripotent stem cells in the last decade has allowed the field to progress closer to medical treatments, the low efficiency of reprogramming a somatic cell to a pluripotent state, and the vast molecular and genomic differences between human embryonic stem cells and human …

Cell Cycle Arrest Associated With Anoxia-Induced Quiescence, Anoxic Preconditioning, And Embryonic Diapause In Embryos Of The Annual Killifish Austrofundulus Limnaeus, Camie Lynn Meller, Robert Meller, Roger P. Simon, Kristin M. Culpepper, Jason E. Podrabsky
Biology Faculty Publications and Presentations
Embryos of the annual killifish Austrofundulus limnaeus can enter into dormancy associated with diapause and anoxia-induced quiescence. Dormant embryos are composed primarily of cells arrested in the G1/G0 phase of the cell cycle based on flow cytometry analysis of DNA content. In fact, most cells in developing embryos contain only a diploid complement of DNA, with very few cells found in the S, G2, or M phases of the cell cycle. Diapause II embryos appear to be in a G0-like state with low levels of cyclin D1 and p53. However, the active form of pAKT is high during diapause II. …
