A novel scalable and stackable nonvolatile memory technology suitable for building fast and dense memory devices is discussed. The memory cell is built by layering a storage element and a selector. The storage element is a Phase Change Memory (PCM) cell [1] and the selector is an Ovonic Threshold Switch (OTS) [2]. The vertically integrated memory cell of(More)
BACKGROUND Papillary thyroid carcinoma (PTC) of the thyroid is the most common endocrine malignancy. High prevalence of an activating point mutation of BRAF gene, BRAF(V600E), has been reported in PTC. We assessed the efficiency of peptide nucleic acid clamp real-time polymerase chain reaction (PNAcqPCR) for the detection of BRAF(V600E) mutation in PTC in(More)
[Purpose] Balance is generally defined as the ability to maintain the body's center of gravity within its base of support and may be categorized by either static or dynamic balance. The purpose of the present study was to evaluate the effect of 8 weeks of balance training on strength, and the functional balance ability of elite weightlifters. [Subjects](More)
OBJECTIVE This study assessed the iron status of Korean male lead workers by measuring the dietary iron intake and biochemical indices, and tested the hypothesis that a high blood lead level is associated with impaired iron function, which results in higher prevalence of iron deficiency when the route of exposure is not the gastrointestinal tract. METHODS(More)
The effects of two antioxidants, superoxide dismutase (SOD) and the flavonoid 3,4-dihydroxyflavone (DHF), on bovine embryo development in vitro were examined. Blastocyst development, total cell and inner cell mass (ICM) numbers, intracellular levels of reactive oxygen species (ROS), apoptotic indices and gene expression levels were examined before and after(More)
[Purpose] The purpose of this study was to investigate the effects of 12 weeks regular aerobic exercise on brain-derived neurotrophic factor (BDNF) and inflammatory factors in juvenile obesity and type 2 diabetes mellitus (T2DM). Obesity and T2DM, typically common among adults, have recently become more prevalent in the Korean juvenile population, affecting(More)
Astrocytes are ubiquitous in the brain and have multiple functions. It is becoming clear that they play an important role in monitoring the neuromicroenvironment, information processing, and signaling in the central nervous system (CNS) in normal conditions and that they respond to CNS injuries. During the development of the CNS, astrocytes play a key role(More)
PURPOSE Secreted protein acidic and rich in cysteine (SPARC), also known as osteonectin or basement-membrane-40 (BM-40), is a member of a family of matricellular proteins, whose functions are to modulate cell-matrix interactions, growth and angiogenesis in colorectal cancer. In this study, the expression of SPARC was evaluated and its correlations with(More)
Lung cancer is one of the most aggressive and lethal form of cancers. Patients with far advanced lung cancer are treated by chemotherapy with or without radiotherapy. However, median survival of these patients is less than 6 months. To increase survival and quality of life for these patients, various forms of complementary treatments have been tried in(More)
We sought to determine whether Alberta Stroke Program Early CT Scores (ASPECTS) derived from baseline noncontrast CT (NCCT) and perfusion CT (CTP) imaging maps can predict clinical outcome after recanalization therapy in acute ischemic stroke of the middle cerebral artery (MCA) territory and whether changes in the ASPECTS from baseline to 24 h after(More)
