Aging Is a Determinant in Anoxia Stress Tolerance in Caenorhabditis Elegans

Aging Is a Determinant in Anoxia Stress Tolerance in Caenorhabditis Elegans

Date: May 2013
Creator: Goy, Jo M.
Description: Oxygen availability is critical for survival for most organisms. The nematode, C. elegans, has been useful for studying genetic regulation of anoxia tolerance due to the oxygen deprivation response mechanisms shared with other metazoans. Studies examining long-term anoxia (72h, LTA) tolerance have only been conducted at adult day 1. To investigate the effect of aging on anoxia tolerance wild-type and mutant strains were exposed to LTA between adult day 1 and day 9. Wild-type isolates and daf-16(mu86) (FOXO transcription factor regulated by insulin-signaling) and aak-2(gt33) (catalytic subunit of AMP-activated protein kinase) strains were anoxia sensitive at day 1 and displayed increased LTA tolerance with aging correlated with reproductive senescence followed by a decline in survivorhsip through day 9. The daf-2(e1370) (insulin receptor homologue of C. elegans), glp-1(e2141) (a lin-12/Notch receptor) and fog-2(q71) (required for spermatogenesis) strains were LTA-tolerant through day 5. I conclude that aging influences LTA-tolerance in a strain- and age-dependent manner. In addition to being LTA-tolerant the daf-2(e1370) and glp-1(e2141) strains have a longevity phenotype that is suppressed by loss of kri-1 or daf-12. While loss of kri-1 did not suppress the LTA-tolerant phenotype of glp-1(e2141) at day 1 the portion of impaired survivors increased at day 3 ...

Determinants of the Applications to the Institutional Care in Turkey: Darulaceze Example

Determinants of the Applications to the Institutional Care in Turkey: Darulaceze Example

Date: May 2013
Creator: Esendemir, Serif
Description: Although institutional care has started to be outmoded in the developed countries with development of different models of care, it still has a considerable place in the developing countries such as Turkey. This is because, changes in the demographic structure, extended family, and urban development of Turkey has brought about several aging problems leading older adults to end up in institutions. Loneliness was one of the significant reasons given in the Social Inquiry Survey of Applicants of Darulaceze Old-Age Institution and the basis for a micro level analysis in this study. Therefore, the main objective of the study was to determine the predictors of loneliness, including age, the state of living alone, functional independence, education, and gender. Analysis of the results indicated that these predictors have significant effects on the loneliness predominantly defined by social factors rather than medical factors. In addition, the meso and macro level analyses were employed to control the micro level analysis and see a general picture of institutional care. Thus, an academic example of diagnosing the main reasons behind the institutional care was presented to understand the context of aging in Turkey.

The Willingness of Older Adults to Evacuate in the Event of a Disaster

The Willingness of Older Adults to Evacuate in the Event of a Disaster

Date: May 2009
Creator: Gray-Graves, Amy Michael
Description: The issue of rising number of disasters, the overwhelming increase in number of older adults, and historically flawed evacuations presents real challenges. Disasters can strike anywhere, any time, and have devastating consequences. Since 1900, the number of Americans 65 and older has increased 12 times (from 3.1 million to 36.3 million). During the next two decades, the number of American baby boomers, now aged 45-64, who turn 65, will increase by 40%. As evidenced by recent disasters, the imperfections and vulnerabilities of flawed evacuations for older adults are still present. This study examined the level of willingness to evacuate among older adults in the event of a disaster. Despite the extensive literature on disasters and evacuation, some significant questions regarding evacuation and older adults have not been addressed. This study addressed the following concerns: (1) What is the willingness among older adults to evacuate when asked to do so by emergency management officials? (2) Does the call to evacuate being mandatory versus voluntary influence the willingness of seniors to evacuate? (3) Do preconditions (Gender, Marital Status, Age, Ethnic Origin, and Education Levels) influence the willingness to evacuate among older adults? The sample population consisted of 765 voluntary participants aged 60 ...

Non-Poissonian statistics, aging and "blinking'" quantum dots.

Non-Poissonian statistics, aging and "blinking'" quantum dots.

Date: August 2004
Creator: Aquino, Gerardo
Description: This dissertation addresses the delicate problem of aging in complex systems characterized by non-Poissonian statistics. With reference to a generic two-states system interacting with a bath it is shown that to properly describe the evolution of such a system within the formalism of the continuous time random walk (CTRW), it has to be taken into account that, if the system is prepared at time t=0 and the observation of the system starts at a later time ta>0, the distribution of the first sojourn times in each of the two states depends on ta, the age of the system. It is shown that this aging property in the fractional derivative formalism forces to introduce a fractional index depending on time. It is shown also that, when a stationary condition exists, the Onsager regression principle is fulfilled only if the system is aged and consequently if an infinitely aged distribution for the first sojourn times is adopted in the CTRW formalism used to describe the system itself. This dissertation, as final result, shows how to extend to the non-Poisson case the Kubo Anderson (KA) lineshape theory, so as to turn it into a theoretical tool adequate to describe the time evolution of ...

Retiring in a Foreign Land: Health Care Issues of US Retirees in Mexico

Retiring in a Foreign Land: Health Care Issues of US Retirees in Mexico

Date: December 2008
Creator: Amin, Iftekhar
Description: This research examined the health care related issues of the American seniors retiring in Mexico. Data for this study were collected through in-person questionnaire surveys and case studies. Findings of this study indicate that US seniors retiring in Mexico are predominantly non-Hispanic whites, married, and more likely to be college graduates. This study challenges the general perception that US seniors move to foreign countries is "amenity-led." The case studies clearly show that many US seniors move there because they are afraid that with reduced income and increased health care needs they would not be able to maintain the same lifestyle after retirement in the US. Climate and the slower pace of life are two other big attractions for seniors' to move to Mexico. A major finding of this study is age, gender, education, use of Medicare for medical care coverage, and chronic medical condition are significant predictors of US seniors' health behavior and health outcomes in Mexico. The policy implications of the findings have been discussed.

Caregiving in Later Life: A Contextual Approach to the Provision of Care

Caregiving in Later Life: A Contextual Approach to the Provision of Care

Access: Use of this item is restricted to the UNT Community.
Date: August 2003
Creator: Worthen, Laura T.
Description: Guided by the life course perspective, this study examined the frequency of caregiving provided by older adults to kin and non-kin. A telephone survey produced a random sample of adults 60 years of age and older, which was predominantly White, with higher income and education levels (n = 278). Bivariate and multivariate analyses tested the impact of demographic characteristics and other variables, conceptualized as physical, human, and social capital, on the frequency of caregiving. Gender, age, health, limitations, education, income, household composition, social contact, and reciprocity were analyzed in multinomial logistic regressions. Caregiving was defined as care provided to sick or disabled persons, with frequency of providing care classified as often, sometimes, and never. The majority of older adults provided at least some care to others over a one-year period, with almost one-third doing so often and only one-quarter never doing so. Most provided care to more than one person, with over one-quarter providing care to multiple friends only. Age failed to predict caregiving involvement when physical and social capital variables were considered. The odds of often providing care are higher for women, although gender did not predict those who never provided care. Having at least some college only significantly ...
