A Drosophila Deg/Enac Channel Subunit Is Required For Male Response To Female Pheromones, Heping Lin, Kevin J. Mann, Elena Starostina, Ronald D. Kinser, Claudio W. Pikielny
Dartmouth Scholarship
Odorants and pheromones as well as sweet- and bitter-tasting small molecules are perceived through activation of G protein-coupled chemosensory receptors. In contrast, gustatory detection of salty and sour tastes may involve direct gating of sodium channels of the DEG/ENaC family by sodium and hydrogen ions, respectively. We have found that ppk25, a Drosophila melanogaster gene encoding a DEG/ENaC channel subunit, is expressed at highest levels in the male appendages responsible for gustatory and olfactory detection of female pheromones: the legs, wings, and antennae. Mutations in the ppk25 gene reduce or even abolish male courtship response to females in the dark, …

Time To Task Failure Differs With Load Type When Old Adults Perform A Submaximal Fatiguing Contraction, Sandra K. Hunter, Ludovic Rochette, Ashley Critchlow, Roger M. Enoka
Time To Task Failure Differs With Load Type When Old Adults Perform A Submaximal Fatiguing Contraction, Sandra K. Hunter, Ludovic Rochette, Ashley Critchlow, Roger M. Enoka
Exercise Science Faculty Research and Publications
Young adults exhibit a longer time to task failure when performing a submaximal isometric contraction by pushing against a force transducer (force task) than when supporting an equivalent inertial load (position task). The purpose of this study was to compare the time to failure for old adults when they performed a force task and a position task with the elbow flexor muscles. Eighteen old adults (72 ± 4 years) performed the force and position tasks at 20% maximal voluntary contraction (MVC) force until task failure. The time to task failure was briefer for the position task (10.6 ± 6.1 min) …
Sexuality And The Aging Adult: The Attitude And Practice Of Physicians And Nurse Practitioners, Susan Runsvold
Sexuality And The Aging Adult: The Attitude And Practice Of Physicians And Nurse Practitioners, Susan Runsvold
Master's Projects
Background: As the population ages, many quality of life issues will generate discussion. One such issue is sexuality of the aging adult. While there is substantial documentation related to the physiology and desires of the aging adult, little is known about medical practitioners' beliefs and practices regarding sexuality. Method: A 14 question survey with a comment section was developed and mailed to 269 physicians and nurse practitioners in Santa Clara County, California. The responses were evaluated using descriptive statistics. The comments received were grouped related to intent or topic. Results: There was no discernible difference between the beliefs and practices …
Viagra: Medical Technology Constructing Aging Masculinity, Gregory Gross, Robert Blundo
Viagra: Medical Technology Constructing Aging Masculinity, Gregory Gross, Robert Blundo
The Journal of Sociology & Social Welfare
Medicalization and commodification of the body through technology in the form of Viagra and other erectile dysfunction drugs is reinforcing the cultural expectations that ageing men are required to age well to maintain youthful masculinity. Ageing well is explored as it relates the construction of masculinity, sexuality and ageing men's bodies.
Effects Of Aging On Pressure-Induced Mapk Activation In The Rat Aorta, Kevin M. Rice
Effects Of Aging On Pressure-Induced Mapk Activation In The Rat Aorta, Kevin M. Rice
Theses, Dissertations and Capstones
With age, the cardiovascular system experiences substantial alterations in cellular morphology and function. The factors regulating these changes are unknown; however, the mitogen activated protein kinase (MAPK) pathways have emerged as critical components for mediating numerous cellular responses including control of cell growth, differentiation and adaptation. Here we compare the expression, basal activation and the ability of increased pressure to activate the MAPK pathways in adult (6 month old), aged (30 month old) and very aged (36 month old) Fischer 344 x Brown Norway F1 Hybrid rats. Histochemical analysis demonstrated an age-related increase in tunica media thickness of approximately 11% …
Common Versus Uncommon Causes Of Dementia, Nicola Lautenschlager, Ralph Martins
Common Versus Uncommon Causes Of Dementia, Nicola Lautenschlager, Ralph Martins
Research outputs pre 2011
When patients present with a dementia syndrome at a young age, the experienced clinician will automatically include uncommon dementias in the diagnostic considerations, as familial uncommon dementias due to genetic mutations frequently present as early-onset dementias. This paper highlights why uncommon dementias due to genetic mutations, although marginal in terms of prevalence numbers in the total population, are of significance in the quest to unravel the underlying cause of common dementias such as Alzheimer's disease (AD), dementia with Lewy bodies (DLB), frontotemporal dementias (FTD) and vascular dementia (VaD).
Education Of Adult Children And Mortality Of Their Elderly Parents In Taiwan, Zachary Zimmer, Linda G. Martin, Mary Beth Ofstedal, Yi-Li Chuang
Education Of Adult Children And Mortality Of Their Elderly Parents In Taiwan, Zachary Zimmer, Linda G. Martin, Mary Beth Ofstedal, Yi-Li Chuang
Poverty, Gender, and Youth
Research shows an older adult’s education is strongly associated with mortality. But in societies such as Taiwan, where families are highly integrated, the education of family members may be linked to survival. Such may be the case in settings where there are large gaps in levels of education across generations and high levels of resource transfers between family members. This Population Council study employs 14 years of longitudinal data from Taiwan to examine the combined effects of education of older adults and their adult children on mortality outcomes of older adults. Results indicate that educational levels of both parent and …
The Prevalence Of Comorbid Chronic Disease In Virginia's Adult Patient Population During The Years 2001 And 2004, Joseph D. Schwartz
The Prevalence Of Comorbid Chronic Disease In Virginia's Adult Patient Population During The Years 2001 And 2004, Joseph D. Schwartz
Theses and Dissertations
Objective: Chronic disease comorbidities, on the rise in the U.S. and Virginia, represent a new challenge to the way medicine is practiced and prescribed. This descriptive study uses Virginia hospital discharge data to describe the prevalence and trends of chronic disease comorbidities present in the state's over-45 population during the years 2001 and 2004.Methods: Data collected by Virginia Health Information was utilized. Adults over the age of 45 years and who selected for race and location were included in this analysis, with an aggregate sample size of 813,336 (N=458,593 [2001]; N=364,743 [2004]). Pearson chi-square analyses determined significant sample population differences …
