BACKGROUND Developmental dysplasia of the hip (DDH) is a common cause of secondary osteoarthritis (OA) in younger patients, and when end-stage OA develops, a THA can provide a solution. Different options have been developed to reconstruct these defects, one of which is impaction bone grafting combined with a cemented cup. To determine the true value of a specific technique, it is important to e...

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...

PURPOSE Open partial nephrectomy has proven long-term oncological efficacy. Long-term outcomes of laparoscopic partial nephrectomy are pending. We present the long-term outcomes of patients undergoing laparoscopic or open partial nephrectomy for a single cT1 renal cortical tumor 7 cm or less. MATERIALS AND METHODS Of 2,246 patients undergoing partial nephrectomy for a single cT1 tumor (1999 t...

PURPOSE Few large European studies have evaluated long-term outcomes for permanent prostate brachytherapy (PPB) as monotherapy for clinically localized prostate cancer. The objective of the present study was to evaluate long-term survival in this patient profile. METHODS AND MATERIALS Retrospective study of 700 patients who underwent transperineal ultrasound-guided iodine-125 PPB (145 Gy) bet...

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...

BACKGROUND This study examines the effects of long-term care insurance (LTCI) on the length of stay (LoS) of senior citizens under the national health insurance of Korea. METHODS The subjects include 3,903,448 people aged 65 and over as of July 1, 2008 when the LTCI was introduced in Korea. This study uses their panel data which traced the records of medical services and LTCI services for the...

We demonstrate the existence of multiple dimensions of private information in the long-term care insurance market. Two types of people purchase insurance: individuals with private information that they are high risk and individuals with private information that they have strong taste for insurance. Ex post, the former are higher risk than insurance companies expect, while the latter are lower r...

objective(s): there is controversial evidence about the effect of methamphetamine (meth) on spatial memory. we tested the time- dependent effects of meth on spatial short-term (working) and long-term (reference) memory in meth –sensitized and withdrawn rats in the morris water maze. materials and methods: rats were sensitized to meth (2 mg/kg, daily/5 days, sc). rats were trained in water maze ...
