Aging

This paper touches upon virus removal technology for groundwater remediation.
Sporadic late-onset Alzheimer's disease (AD) is the most frequent cause of dementia associated with aging. Due to the progressive aging of the population, AD is becoming a healthcare burden of unprecedented proportions. Twenty years ago, it was reported that some indole molecules produced by the gut microbiota possess essential biological activities, including neuroprotection and antioxidant properties. Since then, research has cemented additional characteristics of these substances, including anti-inflammatory, immunoregulatory, and amyloid anti-aggregation features.
This Comment supports SDGs 3 and 10 by highlighting inequities in palliative care between racial groups, including differences in the use of palliative care services, symptom control, and the documentation and implementation of people's end of life wishes.
Background: Many causes of vision impairment can be prevented or treated. With an ageing global population, the demands for eye health services are increasing. We estimated the prevalence and relative contribution of avoidable causes of blindness and vision impairment globally from 1990 to 2020. We aimed to compare the results with the World Health Assembly Global Action Plan (WHA GAP) target of a 25% global reduction from 2010 to 2019 in avoidable vision impairment, defined as cataract and undercorrected refractive error.
Background: Previous studies have shown an excess risk of Alzheimer's disease and related dementias among women. Education is thought to have a causal association with dementia onset. We aimed to investigate the role of education in influencing sex differences in cognitive ageing.
Background: There are growing numbers of adults aging with long-term mobility disabilities. Very little is known about the challenges this population experiences with everyday activities, and such challenges are likely to be greater and more complex than those of older adults who experience mobility declines later in life. Objectives: The current manuscript presents in-depth insights on the specific activity challenges experienced by older adults with long-term mobility disabilities, and the response strategies they employ to overcome those challenges.
Chronological age is a commonly-used time metric, but there may be more relevant time measures in older adulthood. This paper reviews change point modeling, a type of analysis increasingly common in cognitive aging research but with limited application in applied research. Here, we propose a new application of such models for cognitive training studies.

The aggregation of fibrils of hyperphosphorylated and C-terminally truncated microtubule-associated tau protein characterizes 80% of all dementia disorders, the most common neurodegenerative disorders. These so-called tauopathies are hitherto not curable and their diagnosis, especially at early disease stages, has traditionally proven difficult. A keystone in the diagnosis of tauopathies was the development of methods to assess levels of tau protein in vivo in cerebrospinal fluid, which has significantly improved our knowledge about these conditions.
Ectomycorrhizal (ECM) fungi are crucial in the functioning of most forest ecosystems. Increased understanding of ECM symbiosis has led to numerous advancements in environment protection and forestry. The ECM fungi are a diverse group, both phylogenetically and functionally. Research covering their community structure on distinct sites shows that the presence of certain taxa depends on particular stand traits, such as tree species and age structure.
Exercise has been shown to reduce the risk of developing Mild Cognitive Impairment and Alzheimer's disease as well as to improve cognition in healthy and cognitively impaired individuals. However, the mechanisms of these benefits are not well understood. The stress hypothesis suggests that the cognitive benefits attributed to exercise may partially be mediated by changes in the cortisol secretion pattern.
