Highly stable Fe/CeO catalyst for the reverse water gas shift reaction in the presence of HS.

This study focused on evaluating the catalytic properties for the reverse water gas shift reaction (RWGS: CO + H → CO + HO Δ = 42.1 kJ mol) in the presence of hydrogen sulfide (HS) over a Fe/CeO catalyst, commercial Cu-Zn catalyst for the WGS reaction (MDC-7), and Co-Mo catalyst for hydrocarbon desulfurization. The Fe/CeO catalyst exhibited a relatively high catalytic activity to RWGS, compared to the commercial MDC-7 and Co-Mo catalysts.

Preoperative Watchful-Waiting Time and Surgical Outcome of Patients with Non-small Cell Lung Cancer Found by Chest Low-Dose CT Screening.

Backgrounds: Chest low-dose CT screening (LDCTS) has been finding unprecedented numbers of peripheral non-small cell lung cancers (NSCLC) at an early stage and increased the number of patients with surgical indication. It is important to explore the influence of preoperative watchful-waiting time (WWT) on surgical outcomes. Objective is to clarify relationship between WWT and surgical outcomes of LDCTS-finding NSCLC from the view point of treatment delay.

Pulmonary adenocarcinoma possibly developed from the cut-end of small-sized adenocarcinoma in the lung periphery as recurrence 13 years after its wedge resection.

Background: It is a big topic for general thoracic surgery whether still curability can be obtained by limited resection for peripheral small-sized nodules of non-small cell lung cancer (NSCLC) in the current era of frequent computed tomography (CT) use. Accumulation of information on problematic cases would be meaningful for surgeons to select better surgical procedures.

Case Presentation: A 69-year-old man was pointed out an enlarged 2.

Curative resection by splenectomy for solitary splenic metastasis from early gastric cancer: a case report and literature review.

Background: Solitary metastasis of a malignancy to the spleen is rare, particularly for gastric cancer. Only a few case reports have documented isolated splenic metastasis from early gastric cancer. We describe a case of splenic metastasis from early gastric cancer.

[A case of advanced signet ring cell carcinoma of the appendix that responded to S-1 and docetaxel].

A 68-year-old man was admitted to our hospital after testing positive in a fecal occult blood test. He was subsequently diagnosed with advanced signet ring cell carcinoma of the appendix with disseminated peritoneal disease and ascites. Weekly chemotherapy with S-1 was commenced, and after three courses, the tumor shrunk in size and the ascites decreased.
