In the light-adapted vertebrate retina, nitric oxide (NO) modulates synaptic transmission between photoreceptors and second-order neurons. Although NO is believed to be a mediator of adaptation, its effect on photoreceptors in situ is not known yet. Therefore, we studied rod and cone activities in rat eyes in situ, using the electroretinogram (ERG). Rod and(More)
We report a case of a gastric bronchogenic cyst diagnosed via endosonographically guided fine-needle aspiration (EUS-FNA) biopsy. A 60-year-old woman was referred to our hospital for an endoscopic ultrasound (EUS) examination because of a gastric subepithelial lesion detected by upper gastrointestinal endoscopy. EUS examination revealed a lesion that(More)
We describe a case of gastric aberrant pancreas with acute pancreatitis followed up with subsequent endoscopic ultrasound. A 20-year-old woman known to have aberrant pancreas in the stomach was admitted to our hospital because of severe epigastralgia. Laboratory tests showed slight C reactive protein elevation without hyperamylasemia.(More)
The recent progression of endoscopic ultrasonography (EUS) enables EUS-guided transmural drainage based on the EUS-guided fine-needle aspiration biopsy technique. Prior to the development of EUS-guided drainage procedures, the options for treating obstruction of the pancreatobiliary system included surgical drainage, percutaneous drainage using ultrasound(More)
The electroretinogram (ERG) is a non-invasive indicator of retinal function. Light flashes evoke a cornea-negative a-wave followed by a cornea-positive b-wave. Light-adaptation is known to increase the amplitude of cone-dependent b-waves. To identify the underlying mechanism, we recorded rat cone photoresponses in situ, using intravitreally-injected(More)
Overexpression of epidermal growth factor receptor (EGFR) has been found in various epithelial malignancies, including head and neck squamous cell carcinoma (HNSCC), and is associated with increased tumor growth, metastasis, resistance to chemotherapeutic agents and poor prognosis. As such, EGFR is a potential target for antitumor therapy and several EGFR(More)
Caspase-9 (Casp-9) induces death signals by triggering other types of caspase activation, and its expression greatly influences the onset of apoptosis. During the isolation of apoptosis-related genes involved in glucocorticoid (GC)-induced cell death in murine thymic lymphomas, we found that the antisense gene of the transcription factor activator protein-4(More)
Etoposide, a topoisomerase 2 (TOP2) inhibitor, is associated with the development of KMT2A (MLL)-rearranged infant leukemia. An epidemiological study suggested that in utero exposure to TOP2 inhibitors may be involved in generation of KMT2A (MLL) rearrangement. The present study examined the mechanism underlying the development of KMT2A (MLL)-rearranged(More)
When damaged, skeletal muscle regenerates. In the early phases of regeneration, inflammatory cells such as neutrophils/granulocytes and macrophages infiltrate damaged muscle tissue. To reveal the roles of macrophages during skeletal muscle regeneration, we injected an antibody, AFS98 that blocks the binding of M-CSF to its receptor into normal mice that(More)
