Primary Cilia Of The Cardiac Neural Crest & Hedgehog-Mediated Mechanisms Of Congenital Heart Disease, Lindsey A. Fitzsimons May 2022

Primary Cilia Of The Cardiac Neural Crest & Hedgehog-Mediated Mechanisms Of Congenital Heart Disease, Lindsey A. Fitzsimons

Electronic Theses and Dissertations

Elimination of primary cilia in cardiac neural crest cell (CNCC) progenitors is hypothesized to cause a variety of congenital heart defects (CHDs), including atrioventricular septal defects, and malformations of the developing cardiac outflow tract. We present an in vivo model of CHD resulting from the conditional elimination of primary cilia from CNCC using multiple, Wnt1:Cre-loxP, neural crest-specific systems, targeting two distinctive, but critical, primary cilia structural genes: Intraflagellar transport protein 88 (Ift88) or kinesin family member 3A (Kif3a). CNCC loss of primary cilia leads to widespread CHD, where homozygous mutant embryos (MUT) display a variety of outflow tract malformations, septation …


Evaluating The Occurrence Of Age-Related Peripheral Neuropathy In Het3 Mice And Development Of A Whole Tissue Imaging Technique For Analyzing Total Innervation In The Subcutaneous Adipose Depot, Jake Willows Dec 2019

Evaluating The Occurrence Of Age-Related Peripheral Neuropathy In Het3 Mice And Development Of A Whole Tissue Imaging Technique For Analyzing Total Innervation In The Subcutaneous Adipose Depot, Jake Willows

Electronic Theses and Dissertations

Adipose tissue can be characterized as either being a white (energy storing) depot or a brown (energy expending) depot and both have been found to contain dense networks of neural innervation. This adipose nerve supply regulates numerous metabolic functions and likely plays an important role in the function of adipose blood vessels. Recently our lab has shown in the C57BL/6 mouse model that peripheral neuropathy, or the dying back and dysfunction of the nerves in the superficial tissues such as the skin, can extend into the subcutaneous adipose tissue in conditions commonly associated with the neuropathic phenotype (i.e. diabetes, obesity, …

Hypertension And Cognitive Functioning: A Perspective In Historical Context, Merrill F. Elias, Amanda L. Goodell, Gregory A. Dore Jul 2012

Hypertension And Cognitive Functioning: A Perspective In Historical Context, Merrill F. Elias, Amanda L. Goodell, Gregory A. Dore

Maine-Syracuse Longitudinal Papers

Our objective is to characterize the development of the literature on hypertension and cognitive functioning from a historical perspective. This goal was stimulated by the review on “Historical Trends and Milestones in Hypertension Research” in the October 2012 issue of Hypertension. Our specific aims are threefold: (1) to trace and describe the history of this area of research; (2) to identify milestones in knowledge and methods; and (3) to discuss briefly how this literature translates into patient care. The topic is of major relevance to research and practice because hypertension is a well-known risk factor for decline in cognitive performance …


From Blood Pressure To Physical Disability: The Role Of Cognition, Merrill F. Elias, Gregory A. Dore, Adam Davey, Michael A. Robbins, Penelope K. Elias Apr 2010

From Blood Pressure To Physical Disability: The Role Of Cognition, Merrill F. Elias, Gregory A. Dore, Adam Davey, Michael A. Robbins, Penelope K. Elias

Maine-Syracuse Longitudinal Papers

We examined the hypothesis that lowered cognitive performance plays a role in the relation between elevated blood pressure and physical disability in performing basic physical tasks. A community-based sample (N = 1025) free from stroke and dementia (mean age: 61.1 years; SD: 13.0 years; 59.8% women) was used. Using path analysis, systolic and diastolic blood pressures (predictor variable) measured over multiple longitudinal examinations were averaged and related to multiple measures of cognition (intermediate variable) and physical ability (PA; outcome variable) measured at wave 6 of the Maine-Syracuse Study. PA was indexed by time required to execute standing, walking, and turning …


Arterial Pulse Wave Velocity And Cognition With Advancing Age, Merrill F. Elias, Michael A. Robbins, Marc M. Budge, Walter P. Abhayaratna, Gregory A. Dore, Penelope K. Elias Feb 2009

Arterial Pulse Wave Velocity And Cognition With Advancing Age, Merrill F. Elias, Michael A. Robbins, Marc M. Budge, Walter P. Abhayaratna, Gregory A. Dore, Penelope K. Elias

Maine-Syracuse Longitudinal Papers

We hypothesized that carotid-femoral pulse wave velocity (PWV), a marker of arterial stiffness, interacts with age such that the magnitude of associations between PWV and cognitive performance are greater with increasing age and that this interaction is observed despite adjustments for demographic variables, mean arterial pressure, and cardiovascular risk factors. PWV was estimated using applanation tonometry in 409 dementia- and stroke-free participants of the Maine-Syracuse Longitudinal Study (24 to 92 years of age; 62.3% women). Using linear regression analyses in a cross-sectional design, associations between PWV and age and the interaction of PWV and age were examined in relation to …

Blood Pressure And Cognitive Function In An African-American And A Caucasian-American Sample: The Maine-Syracuse Study, Michael A. Robbins, Merrill F. Elias, Penelope K. Elias, Marc M. Budge Apr 2005

Blood Pressure And Cognitive Function In An African-American And A Caucasian-American Sample: The Maine-Syracuse Study, Michael A. Robbins, Merrill F. Elias, Penelope K. Elias, Marc M. Budge

Maine-Syracuse Longitudinal Papers

Objective: The primary purpose of this study was to examine associations between indices of blood pressure (BP) and cognitive function for African-American participants in the Maine-Syracuse Longitudinal Study (MSLS). Corresponding data for the Caucasian-American MSLS participants were included to provide a basis for comparison. Interactions of age with BP indices were also assessed in relation to cognitive function. Methods: Data were drawn from the baseline MSLS questionnaires, medical interviews and examinations, Wechsler Adult Intelligence Scale subtests, and measurements of BP for 1563 participants, of whom 147 were African American. Multiple linear regression analyses were employed to examine the relationship between …

Effects Of Antihypertensive Medications On Quality Of Life In Elderly Hypertensive Women, Sydney H. Croog, Merrill F. Elias, Theodore Colton, Robert M. Baume, Sandra R. Leiblum, C David Jones, H Mitchell Perry, W Dallas Hall Jan 1994

Effects Of Antihypertensive Medications On Quality Of Life In Elderly Hypertensive Women, Sydney H. Croog, Merrill F. Elias, Theodore Colton, Robert M. Baume, Sandra R. Leiblum, C David Jones, H Mitchell Perry, W Dallas Hall

Maine-Syracuse Longitudinal Papers

The impact of antihypertensive medications on the quality of life of elderly hypertensive women has rarely been systematically evaluated in large clinical trials using drugs from the new generations of pharmaceutic preparations. We carried out a multicenter, randomized double-blind clinical trial with 309 hypertensive women aged 60 to 80 years to assess effects of atenolol, enalapril, and isradipine on measures of quality of life over a 22-week period. The patients had mild to moderate hypertension. Hydrochlorothiazide was added to treatment if monotherapy was inadequate in lowering blood pressure. At the conclusion of the trial the three drug groups did not …


Relationship Of Age And Hypertension To Neuropsychological Test Performance, Clyde A. Pentz Iii, Merrill F. Elias, W Gibson Wood, Norman A. Schultz, John Dineen Jan 1979

Relationship Of Age And Hypertension To Neuropsychological Test Performance, Clyde A. Pentz Iii, Merrill F. Elias, W Gibson Wood, Norman A. Schultz, John Dineen

Maine-Syracuse Longitudinal Papers

Young adult (X- = 29) and middle aged (X- =50) hypertensive and normotensive subjects were compared with respect to seven neuropsychological test scores derived from tests on the Halstead-Reitan battery. Age main effects, with inferior performance for the middle aged subjects, were observed for the localization and time portions of the Tactile Performance Test (TPT) and for the Trail Making A test. The multivariate age effect was significant for the composite of seven scores. A multivariate blood pressure main effect was obtained and main effect blood pressure was significant for the category test; hypertensives made more errors than normotensives. A …
