Congress and the Administration are currently exploring various methods of promoting access to long-term care. In this article, an inventory of recent legislative proposals for using the Federal tax code to expand access to long-term care services is provided. Proposals are arrayed along a functional typology that includes tax mechanisms to encourage accumulation of funds, promote purchase of l...
The changing face of long-term care insurance in 1994: profiles and innovations in a dynamic market.
This study examines buyers and nonbuyers of long-term care insurance. The findings show that consumers purchased more comprehensive products in 1994-95 than they did in 1990, and that they appeared to get better value for the premium dollar. While annual sales are increasing at a rate of 25%, the market for long-term care insurance remains small, and many of the market barriers that existed fou...
Assessment of the spatio-temporal dynamics shifting cultivation is important to understand opportunities for land restoration. The past studies on mapping North-East (NE) India lack systematic assessment techniques. We have developed a decision tree-based multi-step threshold (DTMT) method consistent and long-term using Landsat data from 1975 2018. Widely used vegetation indices such as normali...
We have developed a good manufacturing practice for long-term cultivation of fetal human midbrain-derived neural progenitor cells. The generation of human dopaminergic neurons may serve as a tool of either restorative cell therapies or cellular models, particularly as a reference for phenotyping region-specific human neural stem cell lines such as human embryonic stem cells and human inducible ...
Expression of the lux-genes cloned in the recombinant plasmid pPHL7 (Ap r Lux + ) in Escherichia coli Z905 cells was studied in various environments, including model aquatic ecosystems. Expression of the lux-genes strongly depended on the nutritional status of the medium. In particular, the cultivation of cells in nutrient-rich medium favored the maintenance of the initial level of expression o...
BACKGROUND AIMS Spontaneous mutagenesis often leads to appearance of genetic changes in cells. Although human multipotent mesenchymal stromal cells (hMSC) are considered as genetically stable, there is a risk of genomic and structural chromosome instability and, therefore, side effects of cell therapy associated with long-term effects. In this study, the karyotype, genetic variability and clone...
De novo protein synthesis and transcription are necessary for the expression of long-lasting synaptic potentiation [long-term potentiation (LTP)] in hippocampal area CA1 and for the consolidation of long-term memory. The stability of LTP and its longevity require macromolecular synthesis at later stages, but a specific role for early protein synthesis has not been identified. Using electrophysi...
Sleep deprivation disrupts hippocampal function and plasticity. In particular, long-term memory consolidation is impaired by sleep deprivation, suggesting that a specific critical period exists following learning during which sleep is necessary. To elucidate the impact of sleep deprivation on long-term memory consolidation and synaptic plasticity, long-term memory was assessed when mice were sl...
