The worldwide population aged≥65years is increasing and the average life span is expected to increase another 10years by 2050. This extended lifespan is associated with a progressive decline in immune function and a paradoxical state of low-grade, chronic inflammation that may contribute to susceptibility to viral infection, and reduced responses to vaccination. Here we review the effects of aging on innate immune responses to viral pathogens including elements of recognition, signaling, and production of inflammatory mediators...

An increasing number of studies propose circulating microRNAs (miRNAs) as biomarkers for a large number of human diseases including cancer, cardiovascular diseases, neurological pathologies and others. To further validate miRNA as biomarkers it is indispensable to understand the variability of circulating miRNAs in healthy individuals. We determined the longitudinal miRNomes of 90 serum samples from the Janus Serum Bank in Norway, which have been stored between 23 and 40 years at -25 degrees Celsius. We profiled three serum samples with microarrays for 30 individuals, each...

BACKGROUND: Acquired Brain Injuries (ABIs) can result in multiple detrimental cognitive effects, such as reduced memory capability, concentration, and planning. These effects can lead to cognitive fatigue, which can exacerbate the symptoms of ABIs and hinder management and recovery. Assessing cognitive fatigue is difficult due to the largely subjective nature of the condition and existing assessment approaches. Traditional methods of assessment use self-assessment questionnaires delivered in a medical setting, but recent work has attempted to employ more objective cognitive tests as a way of evaluating cognitive fatigue...

Metformin, first line medication in the treatment of type2 diabetes by millions of patients worldwide, causes gastrointestinal adverse effects (i.e. diarrhea) in approximately 30% of patients, frequently leading to discontinuation. Interestingly, metformin was reported to increase life span in a microscopic worm, Caenorhabditis elegans, by decreasing folate and methionine production of bacteria that this worm uses as a food source. Metformin can be expected to have a similar effect on some microorganisms of human gut microbiota...

BACKGROUND: Although ischemic stroke incidence has been in decline over the past 60 years, the same has not been observed among individuals younger than 55 years. Recent reports have shown a substantial increase in young stroke incidence, yet little is known about young stroke survivors. OBJECTIVE: The aim of this study was to examine the disease comorbidity profile and secondary prevention practices in stroke survivors younger than 50 years. METHODS: This study used a retrospective data analysis of secondary stroke prevention practices among young stroke survivors using data from the 2015 National Health Interview Survey...

Parkinson's disease (PD) is a common neurodegenerative disorder, with ageing being a major risk factor. Accordingly, estimates predict an increasing number of PD patients due to our expanding life span. Consequently, developing a true disease-modifying therapy is necessary. In this regard, monogenic PD offers a suitable means for determining pathogenesis. Among monogenic forms of PD, mitochondrial dysfunction may be a major cause and is also likely to be involved in sporadic PD. Thus, mitochondrial impairment may be a common pathway...

Cystic fibrosis (CF) is one of the most frequently occurring inherited human diseases caused by mutations in the cystic fibrosis transmembrane conductance regulator (CFTR) which lead to ample defects in anion transport and epithelial fluid secretion. Existing models lack both access to early stages of CF development and a coeval focus on the gastrointestinal CF phenotypes, which become increasingly important due increased life span of the affected individuals. Here, we provide a comprehensive overview of gastrointestinal facets of CF and the opportunity to model these in various systems in an attempt to understand and treat CF...

AIM: Although accelerated aging profile has been described in bipolar disorder (BD), the biology linking BD and aging is still largely unknown. Reduced levels and/or activity of a protein named Klotho is associated with decreased life span, premature aging and occurrence of age-related diseases. Therefore, this study was designed to evaluate plasma levels of Klotho in BD patients and controls. METHODS: Forty patients with type 1 BD and 30 controls were enrolled in this study...

BACKGROUND: With social structures changing and the average life-span of individuals increasing, Taiwan is experiencing a steady rise in its elderly population. Thus, caring for older parentsis an urgent problem. Many foreign caregivers have been hired tocare for older parents.However, measuring the quality ofinformal care has not yet been fully explored in Taiwan, particularly among older people who are cared for by foreign caregivers in home settings. PURPOSE: The purposes of this study were to understand the differences in quality of care for older Taiwanese and to explore the predictors of quality of care in two types of caregiving...

Individuals' understanding of wealth and power largely determines their use of resources. Moreover, the age range of wealth and power holders is increasing in modern societies. Thus, the current study examines how people of different ages understand wealth and power. As varying future time perspective is related to changes in prioritised life goals, it was tested as a potential mediator of the age differences. A total of 133 participants aged 18-78 years were asked 8 open-ended questions regarding their understanding of the possible use and desired use of wealth and power, after which they reported their future time perspective...

The power generation from renewable power sources is variable in nature, and may contain unacceptable fluctuations, which can be alleviated by using energy storage systems. However, the cost of batteries and their limited lifetime are serious disadvantages. To solve these problems, an improvement consisting in the collaborative association of batteries and supercapacitors has been studied. Nevertheless, these studies don't address in detail the case of residential and large-scale photovoltaic systems. In this paper, a selected combined topology and a new control scheme are proposed to control the power sharing between batteries and supercapacitors...

Older adults in the United States are healthier and more active than ever before. The number of adult drivers 65 years and older is increasing rapidly. However, older drivers are involved in more fatal car incidents per miles driven than any other age group except teenagers. Driving has become very important for older adults because it is critical to their independence and self-esteem. Therefore, the role of health care providers and the interprofessional team is essential to maximizing the life expectancy of driving to match the life span and activity levels of the older adult population...

Sarcoma 180 (S-180) tumour cell line is a stable murine tumour cell line with 98-99% stumour takes capacity in Swiss albino mouse - Mus musculus. 2 Methoxyestradiol (2ME) - a promising anti-neoplastic and anti-angiogenic agent, showed toxicity to host body in higher concentration. Cyclophosphamide (CP), the anti-neoplastic agent has long been used as a chemotherapeutic drug for treatment of different cancers. Our studies have shown that the combination effect of 2ME and CP on S-180 tumour cell line is anti-proliferative and less toxic...

The yeast Hsp26 protein, a conserved a-crystallin small heatshock chaperone, is assembled in to oligomeric complexes, microscopically visible as distinct cytoplasmic foci. We studied at single cell resolution the dynamics of Hsp26p foci assembly, the mode of their inheritance in to progeny cells and the physiological significance of Hsp26p function. We showed that Hsp26p foci are formed upon cells' entry in to stationary phase, but upon re-entry to proliferation they are asymmetrically retained in the mother cells and are absent from the newborn daughters...

Bioprosthetic heart valves (BHVs), fabricated from exogenously crosslinked collagenous tissues, remain the most popular heart valve replacement design. However, the life span of BHVs remains limited to 10-15 years, in part because the mechanisms that underlie BHV failure remain poorly understood. Experimental evidence indicates that BHVs undergo significant changes in geometry with in vivo operation, which lead to stress concentrations that can have significant impact on structural damage. These changes do not appear to be due to plastic deformation, as the leaflets only deform in the elastic regime...

Aging-related diseases show a marked sex bias. For example, women live longer than men yet have more Alzheimer's disease and osteoporosis, whereas men have more cancer and Parkinson's disease. Understanding the role of sex will be important in designing interventions and in understanding basic aging mechanisms. Aging also shows sex differences in model organisms. Dietary restriction (DR), reduced insulin/IGF1-like signaling (IIS), and reduced TOR signaling each increase life span preferentially in females in both flies and mice...

REVIEW

Recent neuroscience models of adolescent brain development attribute the morbidity and mortality of this period to structural and functional imbalances between more fully developed limbic regions that subserve reward and emotion as opposed to those that enable cognitive control. We challenge this interpretation of adolescent development by distinguishing risk-taking that peaks during adolescence (sensation seeking and impulsive action) from risk taking that declines monotonically from childhood to adulthood (impulsive choice and other decisions under known risk)...

Physical activity is important for well-being across the life span. However, links between patterns of adolescent activity, competence perceptions, and young adult outcomes are underexplored. We used data from seven waves of the 4-H Study of Positive Youth Development (N = 5,961) to assess patterns of adolescent athletic participation, whether these patterns were associated with self-perceived athletic competence and young adult physical activity, depressive symptoms, and health, and associations between changes in participation across adolescence and young adult outcomes...
