In this communication, we demonstrate the sequential expression of endogenous molecules, including immediate early genes (IEGs), cytokines, neurotrophins, and neurotrophin receptors in the injured spinal cord. In the acute phase, expression of IEGs and cytokines mRNAs were rapidly upregulated within 1 h in nonneuronal cells in the lesioned sites and the(More)
BACKGROUND AND PURPOSE The necessity for structural MRI is greater than ever to both diagnose AD in its early stage and objectively evaluate its progression. We propose a new VBM-based software program for automatic detection of early specific atrophy in AD. MATERIALS AND METHODS A target VOI was determined by group comparison of 30 patients with very(More)
Exposure to stressful events and elevated level of stress hormones are associated with impaired spatial memory and neuronal damage in the hippocampus. These neurons are considered to be maintained by neurotrophins such as nerve growth factor (NGF), brain-derived neurotrophic factor (BDNF), and neurotrophin-3 (NT-3) and trk family of neurotrophin receptors.(More)
To clarify the process of post-translational modification of L-histidine decarboxylase (HDC), we investigated the conversion of the 74-kDa form of HDC into the 53-kDa form in specialized organella of a rat basophilic/mast cell line (RBL-2H3). With treatment of streptolysin-O, RBL-2H3 cells released approximately 40% of HDC activity accompanied by over 90%(More)
PURPOSE To assess the effectiveness and toxicity of external radiation therapy for superficial esophageal cancer. METHODS AND MATERIALS During the period from March 1979 to November 1996, 78 patients with superficial esophageal cancer received radiation therapy without intracavitary irradiation at nine radiotherapy institutions in Japan. All patients had(More)
L-Histidine decarboxylase (HDC) is a dimer consisting of two identical 53 kDa subunits. On the other hand, the size of HDC deduced from its cDNA sequence is around 74 kDa, indicating that the translated 74 kDa form of HDC is subjected to post-translational processing to generate the 53 kDa form. However, modification of the translated 74 kDa form of HDC in(More)
OBJECTIVES The objectives of this study were to reveal the utility of (18)F-fluorodeoxyglucose positron emission tomography (FDG-PET) within 7 days after chemoradiotherapy to predict prognosis in patients with postoperative recurrent esophageal cancer. MATERIALS AND METHODS Patients scheduled to undergo concurrent chemoradiotherapy for postoperative(More)
PURPOSE Renal cell carcinoma (RCC) is known as a radioresistant tumor, and there are few reports on radiotherapy for primary RCC. We evaluated the efficacy of carbon ion radiotherapy (CIRT) for patients with RCC. METHODS AND MATERIALS Data for patients with RCC who received CIRT were analyzed. A median total dose of 72 GyE (gray equivalents) in 16(More)
PURPOSE To evaluate the factors associated with acute esophagitis in lung cancer patients treated with thoracic radiotherapy. METHODS AND MATERIALS We examined 35 patients with non-small-cell lung cancer (n = 27, 77%) and small-cell lung cancer (n = 8, 23%) treated with thoracic radiotherapy between February 2003 and November 2004. The median patient age(More)
PURPOSE To evaluate the treatment outcome of radiation therapy for 33 loco-regionally recurrent esophageal cancer patients. METHODS Between 1988 and 1997, 33 patients with loco-regional recurrence of esophageal cancer after curative surgery received radiation therapy at an average total dose of 61 Gy. The site of recurrence was the supraclavicular region(More)
