We examine the dynamic interaction of the population age structure, economic dependency, and fertility, paying particular attention to the role of intergenerational transfers. In the short run, a reduction in fertility produces a “demographic dividend” that allows for higher consumption. In the long run, however, higher old-age dependency can more than offset this effect. To analyze these dynam...

Effects of age on cyclosporin A- (CsA) induced gingival overgrowth were investigated in Fischer rats. Rats 15, 30, 45, and 60 days old were fed a diet containing cyclosporin A (120-200 micrograms/g) for 40 days. Gingival overgrowth was estimated by measuring the gingival sulcus depth with a thin color slide probe under a stereoscopic dissecting microscope. The youngest group (15 days old) of ra...

Tumors were induced in Regional Poultry Research Laboratory line 6 chickens inoculated in the wing web with Rous sarcoma virus the Bryan high-liter strain of pseudotype, at 1, 14, and 28 days of age. Tumor regression failed to occur in chicks inoculated at 1 and 14 days of age, but an incidence of regression of 50% was observed in chicks inocu lated at 28 days of age. Chick survival time postin...

In this paper, we introduce and analyze two structured models for the transmission of a vector-borne infectious disease. The first of these models assumes that the level of contagiousness and the rate of removal (recovery) of infected individuals depends on the infection age. In the second model the hosts population is structured with respect to the physical age of the hosts, and the susceptibi...

The age and species dependent characteristics of cutaneous esterase activity were examined in cultured keratinocytes of neonatal and adult humans and of rats at the age of 1, 3, 10, and 50 d. The existence of esterases was characterized using fluorescein-5-isothiocyanate diacetate under a confocal laser scanning microscope. In vitro hydrolysis of ethyl nicotinate (EN), an esterified prodrug of ...

Recent theoretical and empirical work has focused on the variability of network dynamics in maturation. Such variability seems to reflect the spontaneous formation and dissolution of different functional networks. We sought to extend these observations into healthy aging. Two different data sets, one EEG (total n = 48, ages 18-72) and one magnetoencephalography (n = 31, ages 20-75) were analyze...

This study examined to study how respondents rely on the Internet to fulfill the various life goals dimensioned into understanding, orientation and playing goals, and how this dependency relates to the generation of social capital. Further, it examined the resources of social capital in terms of bonding social capita and bridging social capital. In this study quantitative research approach was ...

BACKGROUND AND PURPOSE The purpose of this study was to define predictors of poor outcome after a first-ever stroke. We studied risk factors and stroke severity at baseline in relationship to death, dependency, and stroke recurrence within a year after the event. METHODS The study included a community-based cohort of first-ever stroke patients. Subarachnoid hemorrhage was not included. All pa...

The paper has scrutinized the nexus among poverty, economic growth, employment and dependency ratio in developing countries. The primary intension behind this study is to find out the association between variables such as poverty, economic growth, agricultural and industrial employment and dependency ratio due to the gap in the existing literature. This study fully relies on cross country data ...
