Measurement Matters: Higher Waist-To-Hip Ratio But Not Body Mass Index Is Associated With Deficits In Executive Functions And Episodic Memory, Andree Hartanto, Jose C. Yong Sep 2018

Measurement Matters: Higher Waist-To-Hip Ratio But Not Body Mass Index Is Associated With Deficits In Executive Functions And Episodic Memory, Andree Hartanto, Jose C. Yong

Research Collection School of Social Sciences

Background: The current study aimed to reconcile the inconsistentfindings between obesity, executive functions, and episodic memory byaddressing major limitations of previous studies, including overreliance onbody mass index (BMI), small sample sizes, and failure to control forconfounds.Methods: Participants consisted of 3,712 midlife adults from theCognitive Project of the National Survey of Midlife Development. Executivefunctions and episodic memory were measured by a battery of cognitive functiontests.Results: We found that higher waist-to-hip ratio was associated withdeficits in both executive functions and episodic memory, above and beyond theinfluence of demographics, comorbid health issues, health behaviors,personality traits, and self-perceived obesity. However, higher BMI was notassociated …


Aging Suppresses Skin-Derived Circulating Sdf1 To Promote Full-Thickness Tissue Regeneration, Mailyn A. Nishiguchi, Casey A. Spencer, Denis H. Y. Leung, Thomas H. Leung Sep 2018

Physicians have observed that surgical wounds in the elderly heal with thinner scars than wounds in young patients. Understanding this phenomenon may reveal strategies for promoting scarless wound repair. We show that full-thickness skin wounds in aged but not young mice fully regenerate. Exposure of aged animals to blood from young mice by parabiosis counteracts this regenerative capacity. The secreted factor, stromal-derived factor 1 (SDF1), is expressed at higher levels in wounded skin of young mice. Genetic deletion of SDF1 in young skin enhanced tissue regeneration. In aged mice, enhancer of zeste homolog 2 (EZH2) and histone H3 lysine 27 …

Mining social media messages such as tweets, blogs, and Facebook posts for health and drug related information has received significant interest in pharmacovigilance research. Social media sites (e.g., Twitter), have been used for monitoring drug abuse, adverse reactions to drug usage, and analyzing expression of sentiments related to drugs. Most of these studies are based on aggregated results from a large population rather than specific sets of individuals. In order to conduct studies at an individual level or specific groups of people, identifying posts mentioning intake of medicine by the user is necessary. Toward this objective we develop a classifier …


Production Of Eggs And Sperm, Jia-Min Amanda Tay, Jin Chuan Yong, Norman P. Li Jun 2018

Production Of Eggs And Sperm, Jia-Min Amanda Tay, Jin Chuan Yong, Norman P. Li

The production of gametes is a biological process occurring in organisms that sexually reproduce. Females make gametes called eggs, and males make gametes called sperm. Both egg and sperm cells begin as identical germ cells and are produced through a process of cell division called meiosis, which reduces the number of chromosomes in the germ cell from 46 (diploid) to 23 (haploid). In human males, meiosis begins after birth, and, upon reaching puberty, men produce sperm continuously for the rest of their lives. In human females, meiosis begins before birth and the raw materials for egg cell production are formed …


Bounded Rank Optimization For Effective And Efficient Emergency Response, Pallavi Madhusudan Manohar, Pradeep Varakantham, Hoong Chuin Lau Jun 2018

Bounded Rank Optimization For Effective And Efficient Emergency Response, Pallavi Madhusudan Manohar, Pradeep Varakantham, Hoong Chuin Lau

Effective placement of emergency response vehicles (such as ambulances, fire trucks, police cars) to deal with medical, fire or criminal activities can reduce the incident response time by few seconds, which in turn can potentially save a human life. Owing to its adoption in Emergency Medical Services (EMSs) worldwide, existing research on improving emergency response has focused on optimizing the objective of bounded time (i.e. number of incidents served in a fixed time). Due to the dependence of this objective on temporal uncertainty, optimizing the bounded time objective is challenging. In this paper, we propose a new objective referred to …


Public Understanding Of One Health Messages: The Role Of Temporal Framing, Sungjong Roh, Laura N. Rickard, Katherine A. Mccomas, Daniel J. Decker Feb 2018

Building on research in motivated reasoning and framing in science communication, we examine how messages that vary attribution of responsibility (human vs animal) and temporal orientation (now vs in the next 10 years) for wildlife disease risk influence individuals’ conservation intentions. We conducted a randomized experiment with a nationally representative sample of US adults (N = 355), which revealed that for people low in biospheric concern, messages that highlighted both human responsibility for and the imminent nature of the risk failed to enhance conservation intentions compared with messages highlighting animal responsibility. However, when messages highlighting human responsibility placed the risk …


Learning To Fill The Labor Niche: Filipino Nursing Graduates And The Risk Of The Migration Trap, Yasmin Y. Ortiga Jan 2018

Learning To Fill The Labor Niche: Filipino Nursing Graduates And The Risk Of The Migration Trap, Yasmin Y. Ortiga

Research Collection School of Social Sciences

Overseas recruitment has become a common strategy in filling nurse shortages within U.S. health institutions, sparking the proliferation of nursing programs in the Philippines. Export-oriented education exacerbates a mismatch, however, between available jobs (in both the Philippines and the United States) and the number of nursing graduates, thus increasing joblessness and underemployment among Filipino youth. Pursing higher education as a means to migrate also puts Filipino students at risk of getting caught in a migration trap, where prospective migrants obtain credentials for overseas work yet cannot leave when labor demands or immigration policies change. Such problems highlight the complicated impact …
