Porous silicates containing dilute amounts of tri-, tetra- and penta-valent metal sites, such as TS-1, Sn-β and Fe-ZSM-5, have recently emerged as state of the art catalysts for a variety of sustainable chemical transformations. In contrast with their aluminosilicate cousins, which are widely employed throughout the refinery industry for gas-phase catalytic transformations, such metallosilicates have exhibited unprecedented levels of performance for a variety of liquid-phase catalytic processes, including the conversion of biomass to chemicals, and sustainable oxidation technologies with H2 O2 ...

Anaerobic digestion was investigated as a potential method for on-farm disposal of fallen stock (pig carcases), degrading the carcase material to produce biogas and digestate. The effects of feedstock (sugar beet pulp or pig carcase material or a 50:50 mix) and organic loading rate (50 g-TS L-1 or 100 g-TS L-1 ), during mesophilic (35 °C) anaerobic digestion were investigated. Anaerobic digestion was achieved for all experimental treatments, however the pig carcase material at the higher organic loading rate produced the second highest methane yield (0...

We herein report an interesting case in which a complete response was achieved with oral anticancer monotherapy for unresectable lymph node metastasis after surgery for cecal cancer. A 78-year-old woman was referred to our hospital to undergo a detailed examination for anemia. The examination led to a diagnosis of cecal cancer. She underwent open right hemicolectomy combined with adjacent abdominal wall resection and reconstruction of abdominal wall defects the next month. During follow-up without adjuvant therapy at her request, right iliac lymph node metastasis was detected 5 months later...

The patient was a 66-year-old man. Total abdominal gastrectomy and D2 dissection were performed for gastric cancer (cT3N0M0P0CYXH0, cStage II A). Pathological examination confirmed a diagnosis of Stage III C mucinous adenocarcinoma (pT4pN3pM0, pStage III C). He underwent adjuvant chemotherapy with TS-1(120mg/body). One year after adjuvant chemotherapy, anastomotic stricture was caused. Although it was not possible to point out recurrent lesions on the CT image, we strongly suspected that extrinsic compression around the anastomotic portion was due to peritoneal dissemination recurrence because of symptoms and marked tumor elevation...

Gastric mixed adenoneuroendocrine carcinoma(MANEC)with multiple liver metastases is a rare condition with most data being derived from case reports. We present a case with liver metastases from gastric MANEC that respond remarkably to chemotherapy. Sixty-one-year-old male with severe anemia referred to surgical consultation due to advanced gastric cancer with multiple liver metastases. To relieve uncontrollable tumor bleeding, simple distal gastrectomy for symptom palliation was performed. Based on the tentative diagnosis with gastric poorly differentiated adenocarcinoma, a course of TS-1 and oxaliplatin therapy was administrated...

We report a case of an advanced rectal cancer recurrence that responded completely to chemo-radiotherapy. The patient was an 80-year-old woman. Low anterior resection with D2(prxD3)lymph node dissection was performed. Sixteen months after operation, CEA level elevated but no recurrence foci were found in any image tests. Administration of TS-1 was initiated since recurrence was highly suspected. Twenty seven months after operation, PET-CT detected local recurrence in the posterior wall of the vagina. After construction colostomy, chemo-radiotherapy(60 Gy+oral UFT)was performed and CEA level dropped promptly to the normal value...

A rapid, precise and automated means for the regular inspection and maintenance of a large number of tunnels is needed. Based on the depth study of the tunnel monitoring method, the CNU-TS-1 mobile tunnel monitoring system (TS1) is developed and presented. It can efficiently obtain the cross-sections that are orthogonal to the tunnel in a dynamic way, and the control measurements that depend on design data are eliminated. By using odometers to locate the cross-sections and correcting the data based on longitudinal joints of tunnel segment lining, the cost of the system has been significantly reduced, and the interval between adjacent cross-sections can reach 1-2 cm when pushed to collect data at a normal walking speed...

We report a case of pneumonectomy followed by radical pancreatectomy after oral administration of TS-1 for pancreatic cancer with complications ofa lung tumor. The patient was a 66-year-old woman. A pancreatic tail tumor and 2 lung nodules were detected on CT scans, and were diagnosed as pancreatic cancer and metastatic lung cancer. During a total of1 1 courses ofTS -1 therapy, the pancreatic tumor tended to contract, but both pulmonary nodules remained unchanged. Due to differences in treatment effect, double cancers of the lung and pancreas were suspected, rather than metastatic lung cancers...

A 72-year-old man underwent total gastrectomy for gastric cancer (por2, T3, N2, Stage IIIA). Eleven courses of postoperative chemotherapy with TS-1 (tegafur/gimeracil/oteracil) were administered. Five months after surgery, the serum carcinoembryonic antigen value was slightly elevated. However, computed tomography did not reveal any metastatic lesions in other organs. Two years after surgery, the patient felt a mass in the left mammary. A 2-cm tumor was palpable in the central portion of the breast. Ultrasonography revealed a hypoechoic tumor, which was Class 3 on aspiration biopsy cytological examination...

Design of catalyst particles bearing excellent catalytic activity and suitable surface wettability is the key to the successful application of Pickering interfacial catalysis. In this study, the epoxidations of 1-hexene and cyclohexene with aqueous hydrogen peroxide over hollow titanosilicate TS-1 zeolite were studied as probe reactions to investigate the influence of catalyst surface wettability on its catalytic activity. Hydrophobized hollow TS-1 particles (HTS-1) were fabricated via a post-synthesis desilication treatment with tetrapropylammonium hydroxide (TPAOH) and a post-synthesis silylation treatment with hexamethyldisiloxane (HMDSO)...

BACKGROUND/AIMS: Carnitine plays an important role in the metabolism of fatty acids. It has also been reported that the administration of anticancer drugs may lead to reductions in serum carnitine levels due to decreased activity of organic cation transporter novel 2, which plays a role in the reabsorption of carnitine in the tubules of the kidney. We therefore studied the change in carnitine levels when chemotherapy was administered repeatedly to patients with gastric cancer. METHODS: Ten patients with upper gastrointestinal cancer were enrolled in this study between December 2014 and August 2015...

Biological arsenic oxidation has been suggested as a key biogeochemical process that controls the mobilization and fate of this metalloid in aqueous environments. To the best of our knowledge, only four aerobic chemolithoautotrophic arsenite-oxidizing (CAO) bacteria have been shown to grow via direct arsenic oxidation and to have the essential genes for chemolithoautotrophic arsenite oxidation. In this study, a new CAO bacterium was isolated from a high Andean watershed evidencing natural dissolved arsenic attenuation...

The respiration rate of the thermogenic inflorescences of Japanese skunk cabbage Symplocarpus renifolius can reach 300 nmol s-1 g-1 , which is sufficient to raise spadix temperature (Ts ) up to 15 °C above ambient air temperature (Ta ). Respiration rate is inversely related to Ta , such that the Ts achieves a degree of independence from Ta , an effect known as temperature regulation. Here, we measure oxygen consumption rate (Ṁo2 ) in air (21% O2 in mainly N2 ) and in heliox (21% O2 in He) to investigate the diffusive conductance of the network of gas-filled spaces and the thermoregulatory response...

Adjuvant chemotherapy using TS-1 or capecitabine plus oxaliplatin improves survival outcomes after radical gastrectomy, with both regimens showing similar efficacies. A total of 494 patients with stage II‒III gastric cancer who underwent curative D2 gastrectomy and received adjuvant chemotherapy from April 2004 to June 2014 were included in this study. 219 patients received TS-1, and 275 received platinum-based chemotherapy. The disease-free survival associated with adjuvant chemotherapy with TS-1 was compared with that associated with fluoropyrimidine plus platinum chemotherapy to identify the subgroups that would benefit most from platinum-based chemotherapy...
