Animal germ cells produce PIWI-interacting RNAs (piRNAs), small silencing RNAs that suppress transposons and enable gamete maturation. Mammalian transposon-silencing piRNAs accumulate early in spermatogenesis, whereas pachytene piRNAs are produced later during postnatal spermatogenesis and account for >95% of all piRNAs in the adult mouse testis. Mutants defective for pachytene piRNA pathway pr...
In order to study the relationship between acetylation of histones, chromatin structure and gene activity, the distribution and turnover of acetyl groups among nucleosomal core histones and the extent of histone H4 acetylation were examined in rooster testis cell nuclei at different stages of spermatogenesis. Histone H4 was the predominant acetylated histone in mature testes. Hyperacetylation o...
The mature apo Very Low Density Lipoprotein II (apo VLDLII) mRNA appears in chicken liver within a few hours after estrogen administration. Apart from this mRNA species, shorter RNA molecules hybridizing to apo VLDLII sequences have been detected in rooster liver upon estrogen stimulation. These molecules are present in the non-polyadenylated fraction of the total cellular- and polysomal RNA. N...
BACKGROUND With rapid aging, Singapore faces an increasing proportion of the population with age-related dementia. We used system dynamics methodology to estimate the number and proportion of people with mild, moderate, and severe dementia in future years and to examine the impact of changing family composition on their likely living arrangements. METHODS A system dynamics model was construct...
The elderly population is projected to make up 20% of the total United States population by the year 2030. In addition, epidemiological data suggests increasing prevalence of chronic pain and frailty with advancing age. Pain, being a subjective symptom, is challenging to manage effectively. This is more so in elderly populations with age-specific physiological changes that affect drug action an...
BACKGROUND Balance during quiet stance involves the complex interactions of multiple postural control systems, which may degrade with frailty. The complexity of center of pressure (COP) dynamics, as quantified using multiscale entropy (MSE), during quiet standing is lower in older adults, especially those with falls. We hypothesized that COP dynamics from frail elderly individuals demonstrate l...
Key aspects related to implementation of risk stratification in health care systems-the ASSEHS study
BACKGROUND The lack of proven efficacy of new healthcare interventions represents a problem for health systems globally. It is partly related to suboptimal implementation processes, leading to poor adoption of new interventions. Activation of Stratification Strategies and Results of the interventions on frail patients of Healthcare Services (ASSEHS) EU project (N° 2013 12 04) aims to study curr...
OBJECTIVES To determine the impact on outcomes in patients of the Evercare approach to case management of elderly people. DESIGN Practice level before and after analysis of hospital admissions data with control group. SETTING Nine primary care trusts in England that, in 2003-5, piloted case management of elderly people selected as being at high risk of emergency admission. MAIN OUTCOME ME...
BACKGROUND Partial unweighted treadmill training is a potentially effective modality for improving fitness and function in frail elders. We tested the feasibility of partial unweighted treadmill training in older, mobility-impaired veterans. METHODS Eight mobility-impaired elders participated in partial unweighted treadmill training three times/week for twelve weeks. Outcome measures included...
STUDY OBJECTIVE The study was undertaken to identify any relationship between the mortality of frail elderly people living at home and their housing conditions. DESIGN AND SETTING A cohort of frail elderly people living in Yao City, Osaka Prefecture, Japan was followed for six years. Data on demographic variables, activities of daily living, the disease that was the main cause of the disabili...
