Stripe rust caused by Puccinia striiformis f. sp. tritici is most important and devastating disease of wheat worldwide, which affects the grain yields, quality and nutrition. To elucidate, the genetic basis of resistance, a mapping population of recombinant inbred lines was developed from a cross between resistant Cappelle-Desprez and susceptible cultivar PBW343 using single-seed descent. Variety PBW343 had been one of the most popular cultivars of North Western Plains Zone, for more than a decade, before succumbing to the stripe rust...

Acne vulgaris (acne) is a chronic inflammatory disease prevalent among adolescents and adults, with significant psychological effects. The aetiology of acne is multifactorial. Several pathophysiological associations have been identified in which Propionibacterium acnes plays a major role. This bacteria primarily affects areas containing oil glands including the face, back and trunk, where it causes the formation of seborrhoea and inflammatory lesions. The treatment methods currently in place have side effects...

Objectives: In a well-lit room, observers can generate well-constrained estimates of the distance to an object on the floor even with just a fleeting glimpse. Performance under these conditions is typically characterized by some underestimation but improves when observers have previewed the room. Such evidence suggests that information extracted from longer durations may be stored to contribute to the perception of distance at limited time frames. Here, we examined the possibility that this stored information is used differentially across age...

Dongjuan Xu, Julia A Rivera Drew
Purpose: The majority of research efforts centering on injury among older adults focus on fall-related injuries and short-term consequences of injury. Little is known about the long-term consequences of all-cause nonfatal injuries, including minor injuries. Using a recent, large, and nationally representative sample of the U.S. non-institutionalized civilian population, the current study examines whether older adults who sustained a nonfatal injury (serious and minor) have higher risk of long-term morbidity and mortality outcomes compared with noninjured seniors...

Objectives: Theory of mind (ToM) allows us to detect and make inferences about cognitive and affective mental states. Mixed findings exist regarding (a) age differences in cognitive and affective ToM and (b) what mechanisms may underlie changes in the two components. We addressed these questions by examining the unique and joint contributions of neurocognitive performance, pulse pressure (PP), and biological sex to age differences in cognitive and affective ToM. Method: We tested 86 young and 85 older adults on standardized measures of neurocognitive performance and ToM...

Purpose of the Study: This study investigated the mechanisms of change underlying an activity-based lifestyle intervention, an occupational therapy program aimed at promoting healthy habits, and routines in older adults. We examined two activity-relevant factors as potential mediators linking the intervention to reduced symptoms of depression: activity frequency and global perceptions of activity significance. Social connections and perceived control were assessed to understand how activity-related factors relate to reduced symptoms of depression...

Objectives: Prior elder mistreatment (EM) research has not examined subjective assessments of problem seriousness from the perspective of victims. This study sought to describe the variation in appraisals of perceived EM seriousness among victims of emotional abuse, physical abuse, and neglect and to examine factors that influence varying appraisals using neutralization theory. Methods: Data came from a subsample of EM victims (n = 191) drawn from a representative, population-based study (n = 4,156) of community-dwelling, cognitively intact older adults in New York State...

Objectives: Life-span theories of aging suggest improvements and decrements in individuals' ability to regulate affect. Dynamic process models, with intensive longitudinal data, provide new opportunities to articulate specific theories about individual differences in intraindividual dynamics. This paper illustrates a method for operationalizing affect dynamics using a multilevel stochastic differential equation (SDE) model, and examines how those dynamics differ with age and trait-level tendencies to deploy emotion regulation strategies (reappraisal and suppression)...

Purpose of the Study: Driving is important for older adults' health and well-being, yet little research has examined interventions to maintain driving mobility. As fluid cognitive abilities are strongly linked to driving, targeted cognitive training interventions may impact driving mobility longitudinally. This study assessed the effects of three different cognitive training programs (reasoning, speed of processing, and memory) on driving cessation in older adults across 10 years (n = 2,390)...

Purpose of the Study: Adult day centers (ADCs) offer a heterogeneous group of services that provide for the daily living, care, nutritional, and social needs of older adults. We sought to conceptually map and identify key gaps and findings from literature focused on ADCs, including the types of programs that exist and their associated outcomes on improving health and strengthening health systems. Design and Methods: We conducted a scoping review by searching 5 databases for studies evaluating the outcomes of ADCs specifically for community-dwelling older adults...

Tirth R Bhatta, Jeffrey M Albert, Eva Kahana, Nirmala Lekhak
Objectives: This study employs a novel approach to mediation analysis to clarify the influence of interrelated indicators of life course socioeconomic status (SES) on later life psychological well-being in India. Contrary to traditional approaches (i.e., use of product and difference-in-coefficients), we recognize the role of confounders in the estimation of total, direct, and indirect effects of parental education on respondents' psychological well-being. Method: Drawing from the first wave (2007-2010) of the Study on Global Ageing and Adult Health (SAGE) and adopting a counterfactual approach, we estimate both natural direct and indirect effects of parental education through individual educational attainment (secondarily, through household assets as an additional mediator) on respondents' life-satisfaction and quality of life (QOL)...

Purpose: Early detection of Alzheimer's disease (AD) ensures that affected individuals and their caregivers can make appropriate plans for health care needs, yet many ethnic minorities delay seeking care for AD until the disease has progressed. This study examined attitudes toward care-seeking for AD among Korean Americans (KAs) and identified factors affecting their attitudes. Methods: A cross-sectional survey was used to collect data from 234 KA adults. We conducted hierarchical regression analyses to examine the effects of sociocultural background (age, gender, education, cultural orientation), AD knowledge and exposure to AD, and beliefs about AD (stigma of pity, shame, and public avoidance) and AD care (subjective norm) on KAs' attitudes toward seeking AD care from primary care physicians (PCPs) and AD specialists...

Brenda R Whitehead, Jessica M Blaxton
Purpose of the Study: There is little debate that maintaining some level of physical activity in later life conveys positive benefits both physically and psychologically. What is less understood is the extent to which the type of activity or the length of time spent doing it matters when it comes to these benefits on the daily level. Here, we investigated (a) whether the presence of daily purposeful exercise (Exercise) or non-exercise physical activity (Activity) is sufficient for experiencing day-level benefits, or if time spent matters, and (b) whether there are differential well-being benefits of Exercise and Activity on the daily level...

Similar to organophosphate (OP) nerve agents, diisopropylfluorophosphate (DFP) rapidly and irreversibly inhibits acetylcholinesterase, leading to convulsions that can progress to status epilepticus (SE). However, in contrast to the OP nerve agents, the long-term consequences of DFP-induced SE are not well known. Thus, we characterized the spatiotemporal profile of neuropathology during the first two months following acute DFP intoxication. Adult, male Sprague Dawley rats administered pyridostigmine bromide (0...
