objective: successful bonding of a dental implant to bone, which was referred to as osseointegration by branemark has been well documented. however, long-term prognosis of an implant depends on adequate maintenance and long-term care. an effective maintenance program is required to preserve the health of peri-implant tissues. several techniques have been suggested for this purpose but it is not...

This paper examines the role of a disability approach to the allocation of long-term care benefits. It first highlights the important elements of long-term care that support a disability model. It then reviews the advantages and disadvantages of this approach relative to the traditional indemnity model and summarizes key features of selected domestic and international programs that offer a disa...

The visual system can readily extract numerosity information from brief experiences. This numerical perception is characterized by diminishing accuracy as numerosity increases, and impaired discrimination for similar quantities and large magnitudes. Here we assess whether these properties apply more broadly to numerosity in visual long-term memory. In surprise memory tests, we observed: Remarka...

BACKGROUND The People's Republic of China's population is aging rapidly, partly because of the impact of the one-child policy and improvements in the health care system. Caring for bedridden seniors can be a challenge for many families in the People's Republic of China. OBJECTIVE To identify the inequality of income among different age groups and social statuses, and evaluate the medical burd...

With the rapid aging of the population, Korea introduced public long-term care insurance for older people in 2008. The long-term care insurance was designed as a separate scheme from the national health insurance, with eligibility qualifications and the certification process based on functional disability, benefits and coverage of community-based and institutional care, and a financing structur...

The macaque inferotemporal (IT) cortex, which serves as the storehouse of visual long-term memory, consists of two distinct but mutually interconnected areas: area TE (TE) and area 36 (A36). In the present study, we tested whether memory encoding is put forward at this stage, i.e., whether association between the representations of different but semantically linked objects proceeds forward from...

conclusions the stereotactic brachytherapy for patients with circumscribed and relatively small size tumors appears to be a safe, feasible, and minimally-invasive treatment. results thirteen patients were male and 16 were female, with the median age of 29 years (range, 2.5 – 64 years). the median follow-up was 95 (range, 6 – 240) months. based on pignatti classification, 10 patients were at low...

introduction: stress is associated with neurological and cognitive disorders. it has been suggested that doxepin, in addition to its influence on the content of neurotransmitters, has probable neuroprotective effects as well. therefore, the aim of this study was to investigate the effects of doxepin on synaptic plasticity and brain-derived neurotrophic factor (bdnf) gene expression in the rat h...

long-term potentiation (ltp) is a reflection of synaptic plasticity that induced by specific patterns of synaptic activity and has an important role in learning and memory. the first clue of the potential role of glutamate receptors in ltp was in 1991 with the observation that the mglur agonists 1-amino-1, 3-cyclopentanedicarboxylic acid (acpd), increased ltp. studies have shown that acpd induc...

The term synaptic plasticity points to a series of persistent changes related to the activity of synapses. Long-term potentiation (LTP) is a reflection of synaptic plasticity that has an important role in learning and memory. LTP is a long-lasting increase of synaptic activity due to enhancement of excitatory synaptic transmission after a high-frequency train of electrical stimulations. Differe...
