Articles

In this work, our aim was to determine whether L-arginine (a known insulinotropic amino acid) can promote a shift of b-cell intermediary metabolism favoring glutathione (GSH) and glutathione disulfide (GSSG) antioxidant responses, stimulus–secretion coupling and functional integrity. Clonal BRIN-BD11 b-cells and mouse islets were cultured for 24 h at various L-arginine concentrations (0–1.15 mmol/l) in the absence or presence of a proinflammatory cytokine cocktail (interleukin 1b, tumour necrosis factor a and interferon g). Cells were assessed for viability, insulin secretion, GSH, GSSG, glutamate, nitric oxide (NO), superoxide, urea, lactate and for the consumption of glucose and glutamine. Protein levels of …

Anti-Amyloid-Β Single-Chain Antibody Brain Delivery Via Aav Reduces Amyloid Load But May Increase Cerebral Hemorrhages In An Alzheimer's Disease Mouse Model, Jinghong Kou, Hong-Duck Kim, Hiroaki Taguchi, Sudhir Paul, Selvarangan Ponnazhagan, Ken-Ichiro Fukuchi

NYMC Faculty Publications

Accumulation of amyloid-β protein (Aβ) in the brain is thought to be a causal event in Alzheimer's disease (AD). Immunotherapy targeting Aβ holds great promise for reducing Aβ in the brain. Here, we evaluated the efficacy and safety of anti-Aβ single-chain antibody (scFv59) delivery via recombinant adeno-associated virus (rAAV) on reducing Aβ deposits in an AD mouse model (TgAβPPswe/PS1dE9). First, delivery of scFv59 to the brain was optimized by injecting rAAV serotypes 1, 2, and 5 into the right lateral ventricle. Symmetrical high expression of scFv59 was found throughout the hippocampus and partly in the neocortex in both hemispheres via …

Sleep Estimates In Children: Parental Versus Actigraphic Assessments, Ehab A. Dayyat, Karen Spruyt, Dennis L. Molfese, David Gozal

Center for Brain, Biology, and Behavior: Faculty Publications

Background: In the context of increasing awareness about the need for assessment of sleep duration in community and clinical settings, the use of questionnaire-based tools may be fraught with reporter bias. Conversely, actigraphy provides objective assessments of sleep patterns. In this study, we aimed to determine the potential discrepancies between parentally-based sleep logs and concurrent actigraphic recordings in children over a one-week period.

Methods: We studied 327 children aged 3–10 years, and included otherwise healthy, nonsnoring children from the community who were reported by their parents to be nonsnorers and had normal polysomnography, habitually-snoring children from the community …

Connolly, Kerry Kilborn, Dennis L. Molfese, Charles Perfetti, Allen D. Malony

Center for Brain, Biology, and Behavior: Faculty Publications

We present MINEMO (Minimal Information for Neural ElectroMagnetic Ontologies), a checklist for the description of event-related potentials (ERP) studies. MINEMO extends MINI (Minimal Information for Neuroscience Investigations)to the ERP domain. Checklist terms are explicated in NEMO, a formal ontology that is designed to support ERP data sharing and integration. MINEMO is also linked to an ERP database and web application (the NEMO portal). Users upload their data and enter MINEMO information through the portal. The database then stores these entries in RDF (Resource Description Framework), along with summary metrics, i.e., spatial and temporal metadata. Together these spatial, temporal, and functional …

How Loss Of Neurofibromin In Oligodendrocytes Affects The Brain, Debra A. Mayes, Tilat A. Rizvi, Nathan T. Kolasinski, S. Miller, Nancy Ratner

Neuroscience, Cell Biology & Physiology Faculty Publications

Neurofibromatosis type 1 patients are predisposed to central nervous system (CNS) phenotypes including enlarged brains, delayed acquisition of motor skills, brain tumors, and cognitive deficits. Imaging and pathologic analysis suggest that changes in white matter myelination may underlie both the enlargement of white matter tracts that contributes to megancephaly, and/or hyper-intense signals visualized on MRI. To study the role(s) of Nf1 and HRasin oligodendrocytes, we examined the optic nerve and corpus callosum,myelinated fiber tracts.We studiedNf1heterozygous mice,tamoxifen-induced Nf1 loss in mature oligodendrocytes (Plp-CreERT), and a new transgenic model in which the CNPase promoter drives expression of HRasG12V. Activated HRas and loss …

Assessing Human Immunodeficiency Virus Testing Attitudes Among African Immigrants, Hazel Namona Nachembe Jan 2011

Assessing Human Immunodeficiency Virus Testing Attitudes Among African Immigrants, Hazel Namona Nachembe

Theses Digitization Project

This study attempted to assess and explore the attitudes of African immigrants towards HIV testing and seeking HIV services in the U.S. The pool of HIV/AIDS cases among blacks at risk in the United States does not clearly distinguish between African Americans and Black African immigrants in regard to attitudes on HIV testing. A closer exploration of African immigrants as specific black sub-groups within the larger group of blacks or African Americans infected with HIV may help distinguish and explain the increase in incidents and high risk behaviors among blacks.


The Effects Of Childhood Sexual Abuse On Women In Recovery For Substance Abuse, Barbara Eileen Egan Jan 2011

The Effects Of Childhood Sexual Abuse On Women In Recovery For Substance Abuse, Barbara Eileen Egan

Theses Digitization Project

This study assessed if women who are survivors of Childhood Sexual Abuse and receive treatment for this issue, when they were in treatment for substance abuse, stayed sober longer and thus experienced a healthier and happier recovery. The benefit of this research is two-fold as it not only leads to better treatment programs for women who have this co-occurring condition, it also allows for better treatment outcomes and as a result is more cost effective for treatment agencies. The data was collected confidentially through surveys that were distributed at 10 local Alcoholic's Anonymous meetings in the Inland Empire area.

Synchronization Analysis Of Voltage-Sensitive Dye Imaging During Focal Seizures In The Rat Neocortex, Sonya Bahar, Daisuke Takeshita Jan 2011

Synchronization Analysis Of Voltage-Sensitive Dye Imaging During Focal Seizures In The Rat Neocortex, Sonya Bahar, Daisuke Takeshita

Physics Faculty Works

Seizures are often assumed to result from an excess of synchronized neural activity. However, various recent studies have suggested that this is not necessarily the case. We investigate synchronization during focal neocortical seizures induced by injection of 4-aminopyridine (4AP) in the rat neocortex in vivo. Neocortical activity is monitored by field potential recording and by the fluorescence of the voltage-sensitive dye RH-1691. After removal of artifacts, the voltage-sensitive dye (VSD) signal is analyzed using the nonlinear dynamics-based technique of stochastic phase synchronization in order to determine the degree of synchronization within the neocortex during the development and spread of each …

Perinatal Or Adult Nf1 Inactivation Using Tamoxifen-Inducible Plpcre Each Cause Neurofibroma Formation, Debra A. Mayes, Tilat A. Rizvi, Jose A. Cancelas, Nathan T. Kolasinski, Georgianne M. Ciraolo, Anat O. Stemmer-Rachamimov, Nancy Ratner

Neuroscience, Cell Biology & Physiology Faculty Publications

OBJECTIVES

Neurofibromas are tumors initiated by biallelic mutation of the NF1 tumor suppressor gene in the Schwann cell lineage. One idea within the field suggests that Nf1loss must occur within progenitor cells present within a critical window during Schwann cell development in order for neurofibromas to form. To test this hypothesis and to examine whethermyelinating Schwann cells can serve as aneurofibroma cell of origin, Nf1 loss was induced at perinatal or adult timepoints using a tamoxifen-inducible Plp-CreERT driver.

RESULTS

Perinatal loss of Nf1 resulted in small neurofibromas late in life, while adult loss caused large neurofibromas and morbidity beginning …

The Influence Of School Eating Environment On Children's Eating Behaviors: An Examination Of The Snda-Iii, Sabrina M. Neeley

Master of Public Health Program Student Publications

The prevalence of childhood overweight and obesity in the United States has prompted researchers to examine the factors that contribute to children’s food choices and consumption. Schools provide ample opportunities to teach children healthy eating habits, as well as create eating environments that are conducive to healthy eating behaviors. The National School Lunch Program (NSLP) provides federally assisted meals to millions of children every day and the assessment of the NSLP provides an opportunity to examine the school-eating environment. Hierarchical and logistic modeling of the SNDA-III, the USDA assessment of the NSLP, was conducted to determine relationships between environmental factors …

Reduction Of Exacerbations By The Pde4 Inhibitor Roflumilast--The Importance Of Defining Different Subsets Of Patients With Copd, Stephen I. Rennard, Peter M.A. Calverley, Udo M. Goehring, Dirk Bredenbröker, Fernando J. Martinez Jan 2011

Reduction Of Exacerbations By The Pde4 Inhibitor Roflumilast--The Importance Of Defining Different Subsets Of Patients With Copd, Stephen I. Rennard, Peter M.A. Calverley, Udo M. Goehring, Dirk Bredenbröker, Fernando J. Martinez

Journal Articles: Pulmonary & Critical Care Med

BACKGROUND: As chronic obstructive pulmonary disease (COPD) is a heterogeneous disease it is unlikely that all patients will benefit equally from a given therapy. Roflumilast, an oral, once-daily phosphodiesterase 4 inhibitor, has been shown to improve lung function in moderate and severe COPD but its effect on exacerbations in unselected populations was inconclusive. This led to the question of whether a responsive subset existed that could be investigated further.

METHODS: The datasets of two previous replicate, randomized, double-blind, placebo-controlled, parallel-group studies (oral roflumilast 500 μg or placebo once daily for 52 weeks) that were inconclusive regarding exacerbations were combined in …
