Informationist Support For A Study Of The Role Of Proteases And Peptides In Cancer Pain, Alisa Surkis, Aileen Mccrillis, Richard Mcgowan, Jeffrey Williams, Brian L. Schmidt, Markus Hardt, Neil Rambo

Journal of eScience Librarianship

Two supplements were awarded to the New York University Health Sciences Libraries from the National Library of Medicine's informationist grant program. These supplements funded research support in a number of areas, including data management and bioinformatics, two fields that the library had recently begun to explore. As such, the supplements were of particular value to the library as a testing ground for these newer services.

This paper will discuss a supplement received in support of a grant from the National Institute of Dental and Craniofacial Research (PI: Brian Schmidt) on the role of proteases and peptides in cancer pain ...

Investigating Adenosine’S Role In Controlling The Cerebral Metabolic Rate Of Oxygen Following Hypoxia-Ischemia, Mustafa Ridha

Electronic Thesis and Dissertation Repository

The cerebral metabolic rate of oxygen (CMRO2) has been shown to be an early indicator of hypoxia-ischemia (HI); however, the mechanisms controlling post-HI CMRO2 are not clear. One potential mechanism is the activation of the adenosine A1 receptor due to increased adenosine concentrations during the insult. The present study investigated if the specific adenosine A1 antagonist, DPCPX, would reduce the typical reduction in CMRO2 and electrical cortical activity following HI. Measurements of CMRO2 and electrical cortical activity were obtained on piglets by near-infrared spectroscopy (NIRS) and amplitude-integrated electroencephalography (aEEG), respectively. The post-HI measurements of CMRO2 and mean aEEG background voltage ...

Sex Differences In Cell Death And Steroid Hormone Receptors In Cortical Explants, Amanda L. Trout

Theses and Dissertations--Physiology

Estrogens, such as the biologically active 17-b estradiol (E2) have many actions in the male and female brain. Not only does E2 regulate reproductive behavior in adults, it organizes and activates the brains of younger animals in a sex-specific manner. In addition, many human studies have shown E2 to provide protection against a variety of neurological disorders, including stoke. These studies have been controversial and depend largely on the type and timing of hormone replacement. Animal studies are much less controversial and clearly demonstrate a neuroprotective role for E2 following ischemic brain injury. Because much of E2 neuroprotection requires sex ...

The Effect Of Acute Exercise On The Production Of Reactive Oxygen Species And Inflammatory Markers In Healthy Pre-Pubertal And Adult Males, Maple Liu

Open Access Dissertations and Theses

An acute bout of exercise causes short-term changes in the immune system in both children and adults. It has been well-established that exercise induces an inflammatory response. Especially in children, cytokines play an important role in balancing anabolic and catabolic processes of growth. Existing evidence suggests cross-talk between inflammation and oxidative stress. Reactive oxygen species are also found to transiently increase in response to exercise, affecting muscle adaptation post-exercise. Characterizing the exercise-induced inflammatory and oxidative stress responses in children compared to adults will start clarifying the transition from the child phenotype to that of an adult. Ten children aged 8-10 ...

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
