The hypothalamic suprachiasmatic nucleus (SCN) of the mammal is the circadian pacemaker responsible for generation of circadian rhythms. Several immediate-early genes are expressed in the SCN by light stimuli which induce phase shifts of animal activity rhythms. In the present study, we investigated whether Homer, a PDZ-like protein which is rapidly induced(More)
Calcium and nitric oxide (NO) are important messengers for the activity-dependent immediate-early gene (IEG) expressions in neuronal cells. In the present study, we have investigated the roles of two mitogen-activated protein (MAP) kinases, extracellular signal-regulated protein kinase (ERK) and p38 MAP kinase (p38 kinase) in calcium- and NO-induced c-fos(More)
Protein kinase A (PKA) plays an essential role in the depolarization-induced c-fos expression in PC12 cells although the exact mechanism is unknown. Here we demonstrate that PKA is required for depolarization-induced activation of both extracellular signal-regulated kinase (ERK) and p38 mitogen-activated protein (MAP) kinase in PC12 cells. In addition, we(More)
BACKGROUND Immune reconstitution (IR) after hematopoietic stem cell transplantation (HSCT) reduces transplantation-related complications such as infection and improves HSCT outcomes. METHODS We retrospectively analyzed IR of lymphocyte subpopulations in 38 pediatric patients for hematologic malignant diseases after allogeneic HSCT from April 2006 to July(More)
Anemia caused by vitamin B12 deficiency resulting from inadequate dietary intake is rare in children in the modern era because of improvements in nutritional status. However, such anemia can be caused by decreased ingestion or impaired absorption and/or utilization of vitamin B12. We report the case of an 18-year-old man with short stature, prepubertal(More)
We investigated the developmental changes of detergent-insoluble characteristics of NMDA and AMPA receptor subunits in the synaptic membranes prepared from the rat cerebral cortex. At postnatal day (PND) 1, the majority of NMDAR1 and NMDAR2B subunits of NMDA receptors in the synaptic membranes were insoluble to the treatment of 1% Triton X-100. The(More)
It has been suggested that the increased frequency of trigger finger (TF) after carpal tunnel release (CTR) may be caused by the volar migration of the flexor tendons at the wrist altering the tendon biomechanics at the A1 pulley. This hypothesis has not been validated. We performed pre- and post-operative ultrasonography (USG) on the affected wrists of 92(More)
The aims of this study were to assess the efficacy of a newly designed radiological technique (the radial groove view) for the detection of protrusion of screws in the groove for the extensor pollicis longus tendon (EPL) during plating of distal radial fractures. We also aimed to determine the optimum position of the forearm to obtain this view. We(More)
BACKGROUND Despite advances in chemotherapy, the prognosis of relapsed acute lymphoblastic leukemia (ALL) remains poor. Few studies on relapsed ALL have reported the importance of intensive consolidation followed with or without allogeneic hematopoietic stem cell transplantation (HSCT). METHODS We evaluated the post-relapse outcomes in 47 Korean children(More)
