INTRODUCTION Chronic necrotizing pulmonary aspergillosis usually occurs in mildly immune-compromised hosts or those with underlying pulmonary disease. The radiographic pattern of chronic necrotizing pulmonary aspergillosis is typically a progressive upper lobe cavitary infiltrate with pleural thickening. We report here an atypical case of chronic(More)
Silent information regulator 2 (SIR2) is a highly conserved protein, the mammalian orthologue of which, SIRT1, exhibits histone deacetylase activity. SIRT1 is involved not in only longevity due to caloric restriction but in a variety of diseases such as diabetes, cardiovascular dysfunction and neurodegeneration.(More)
AIMS AND BACKGROUND It is reported that about 20% of patients with small cell lung cancer (SCLC) receive third-line chemotherapy. We conducted a retrospective study to investigate the outcome and prognostic factors of patients with SCLC who receive third-line chemotherapy. METHODS AND STUDY DESIGN The medical records of patients with SCLC who received(More)
BACKGROUND AND OBJECTIVE In asthma, reduced histone deacetylase activity and enhanced histone acetyltransferase activity in the lungs have been reported. However, the precise function of Sirtuin 1 (Sirt1), a class III histone deacetylase, and the effect of the Sirt1 activator SRT1720 on allergic inflammation have not been fully elucidated. METHODS The(More)
It has been reported that beta2-agonists may potentially exert some anti-inflammatory action in addition to bronchodilation that may contribute to their beneficial effects on asthma control. Bronchial epithelial cells are well known to respond to a range of stimuli by producing various biologically active mediators that can influence airway inflammation.(More)
Adenosylhomocysteine hydrolase (SAHase)-like protein 1 (SAH-L), also called inositol 1,4,5-triphosphate receptor-binding protein (IRBIT) is a novel protein involved in fish embryo development and calcium release in mammalian cells through protein-protein interactions. To better understand its reaction mechanism, purified protein is indispensable. Here we(More)
INTRODUCTION Miliary brain metastasis is an extremely rare form of brain metastasis which can present with atypical imaging findings. We report the case of a patient with miliary brain metastasis of lung cancer showing calcification in metastatic lesions. CASE PRESENTATION A 68-year-old Japanese woman was diagnosed with lung adenocarcinoma. Brain computed(More)
AIMS AND BACKGROUND Amrubicin monotherapy can be an effective treatment option for patients with recurrent small cell lung cancer (SCLC). We conducted this retrospective study to investigate the prognostic factors in patients with recurrent SCLC receiving amrubicin monotherapy. METHODS The associations between survival and clinical data, including the(More)
A 23-year-old Japanese man was admitted to our hospital because of dry cough and lacrimal gland swelling. Laboratory findings showed hypergammaglobulinemia (4859 mg/dl), hypocomplementemia (CH50 13 U/ml), and hyperamylasemia. CT revealed a marked swelling of the bilateral lacrimal glands, diffuse patchy infiltration in the bilateral lung fields, and(More)
