Photosynthesis converts light energy into biologically useful chemical energy vital to life on Earth. The initial reaction of photosynthesis takes place in photosystem II (PSII), a 700-kilodalton homodimeric membrane protein complex that catalyses photo-oxidation of water into dioxygen through an S-state cycle of the oxygen evolving complex (OEC). The(More)
BACKGROUND The prognostic impact of neutrophil to lymphocyte ratio (NLR) in non-small cell lung cancer (NSCLC) was examined using patients with a follow-up period more than 5 years. PATIENTS AND METHODS Two hundred and eighty four consecutive resected NSCLC patients were reviewed retrospectively. In this study, patients who were treated with a follow-up(More)
Crystal structures of endopolygalacturonase from Stereum purpureum were solved in native and two galacturonic acid complex states at atomic resolution. Endopolygalacturonase catalyzes the hydrolysis of alpha-1,4-glycosidic linkage of polygalacturonate in pectin. The native structure was determined by the multiple wavelength anomalous dispersion method and(More)
BACKGROUND/AIMS We performed a randomized trial to evaluate whether fixation of the greater omentum to the peritoneum prevents delayed gastric emptying and other complications after left-sided hepatectomy. METHODOLOGY Patients undergoing left lateral segmentectomy or left hepatectomy were randomly assigned to a fixation group (n=24) and a non-fixation(More)
Relationship between thrombocytosis and poor prognosis has been reported in lung cancer. However, the majority of previous studies included many advanced stage and small cell lung cancer patients. Few studies focused on resectable non-small cell lung cancer patients. In the present study, therefore, consecutive 240 non-small cell lung cancer patients who(More)
BACKGROUND/PURPOSE Delayed gastric emptying (DGE) sometimes occurs after left hepatectomy with lymphadenectomy. We performed fixation of the greater omentum to the peritoneum to prevent DGE and other complications in patients undergoing left hepatectomy with lymphadenectomy for cholangiocarcinoma. METHODS Patients undergoing left hepatectomy with(More)
BACKGROUND Thymic carcinoma is a rare neoplasm with extremely poor prognosis. To evaluate the biological characteristics of thymic carcinoma, we reviewed 8 patients. METHODS There were 2 men and 6 women: ages ranged from 19 to 67 years old (mean 54.8 years). None of these patients had concomitant myasthenia gravis and pure red cell aplasia. No patient had(More)
We describe herein a case of inflammatory malignant fibrous histiocytoma (IMFH) of the gallbladder that subsequently metastasized to the ascending colon and later to the stomach. A 70-year-old Japanese man with a palpable mass in the right upper quadrant of the abdomen was referred to our hospital for investigation and treatment. Laboratory data showed(More)
Mucoceles of the appendix are a group of mucus-filled lesions causing obstructive dilation of the ileocecal appendix. We report a rare case of giant appendiceal mucocele. A 48-year-old woman, with no discomfort, was admitted to our hospital after a mass was detected in the right lower quadrant of the abdomen. The patient underwent right hemicolectomy on the(More)
Lymph node (LN) metastases from hepatocellular carcinoma (HCC) are considered uncommon. We describe the surgical resection of a solitary para-aortic LN metastasis from HCC. A 65-year-old Japanese man with B-type liver cirrhosis was admitted for the evaluation of a liver tumor. He had already undergone radiofrequency ablation, transcatheter arterial(More)
