Multi-anode enhanced the bioelectricity generation in air-cathode microbial fuel cells towards energy self-sustaining wastewater treatment.

Microbial fuel cells (MFCs) hold considerable promise for harnessing the substantial energy resources present in wastewater. However, their practical application in wastewater treatment is limited by inadequate removal of organic matter and inefficient power recovery. Previous studies have investigated aeration as a method to enhance the removal of organic matter, but this method is energy-intensive.

Effect of Ion Selectivity on Current Production in Sewage Microbial Fuel Cell Separators.

This study compared the performance of two microbial fuel cells (MFCs) equipped with separators of anion or cation exchange membranes (AEMs or CEMs) for sewage wastewater treatment. Under chemostat feeding of sewage wastewater (hydraulic retention time of approximately 7 h and polarization via an external resistance of 1 Ω), the MFCs with AEM (MFC) generated a maximum current that was 4-5 times greater than that generated by the MFC with CEM (MFC). The high current in the MFC was attributed to the approximately neutral pH of its cathode, in contrast to the extremely high pH of the MFC cathode.

A multicenter phase II trial of preoperative chemoradiotherapy with S-1 plus oxaliplatin and bevacizumab for locally advanced rectal cancer.

Background: We clarified the safety and efficacy of preoperative chemoradiotherapy for locally advanced rectal cancer using a multidrug regimen (S-1 + oxaliplatin + bevacizumab).

Methods: This multicenter phase II trial involved 47 patients with locally advanced rectal cancer. All patients received S-1 orally (80 mg/m/day on days 1-5, 8-12, 15-19, and 22-26) and infusions of oxaliplatin (50 mg/m on days 1, 8, 15, and 22) and bevacizumab (5 mg/kg on days 1 and 15).

Effects of chemotherapy on quality of life and night-time sleep of colon cancer patients.

Background : The aim of this study was to investigate quality of life (QOL) and night-time sleep disturbance in colon cancer patients with middle risk chemotherapy for proper antiemetic therapy. Methods : The study enrolled 139 patients with colorectal cancer. All patients received oxaliplatin or irinotecan-based chemotherapy.

Three cases of paediatric pancreatic injury involving the main pancreatic duct.

We report on 3 patients aged 9-12 years with pancreatic injury involving the main pancreatic duct. None of them presented with shock. They were initially transported to secondary emergency care facilities, leading to delays in diagnosis and treatment.

Role of heat shock factor 1 expression in the microenvironment of intrahepatic cholangiocarcinomas.

Background And Aim: Heat shock factor 1 (HSF1), a master regulator of heat shock response, has been shown to play a multifaceted role in cancer progression. However, the clinical significance and biological effect of HSF1 expression in intrahepatic cholangiocarcinoma (IHCC) remain unknown.

Methods: Forty-nine patients with IHCC who underwent hepatic resection were enrolled in this study.

Loss of Fbxw7 expression is a predictor of recurrence in colorectal liver metastasis.

Background: Fbxw7 is a tumor suppressor through ubiquitination and degradation of multiple oncoproteins. Loss of Fbxw7 is frequently observed in various human cancers. In this study, we examined the role of Fbxw7 expression in colorectal liver metastasis (CRLM) and its mechanism.

Dedifferentiated Liposarcoma Masquerading as Rhabdomyosarcoma.

We present a rare case of retroperitoneal dedifferentiated liposarcoma (DDLPS) masquerading as rhabdomyosarcoma. The patient was a 74-year-old man, complaining a loss of appetite. Abdominal computed tomography revealed a retroperitoneal mass, 10 cm in diameter, between the liver and the right adrenal gland.

Propensity score-matched study of laparoscopic and open surgery for colorectal cancer in rural hospitals.

Background And Aim: Various randomized clinical studies have suggested that short- and long-term outcomes of laparoscopic surgery (LAP) for colorectal cancer are comparable with those of open surgery (OP). However, these studies were performed in high-volume hospitals. The aim of the present study was to compare the outcomes of LAP versus OP for colorectal cancer in rural hospitals.

A case of perinephric liposarcoma which recurred ten years later from the initial operation.

A 58-year old man was referred to our hospital for treatment of an abdominal mass. As for him, tumor resection with right nephrectomy had been performed ten years ago for a giant well-differentiated perinephric liposarcoma. CT examination showed a huge tumor shadow in the abdominal cavity.

Gastric cancer with choriocarcinoma and yolk sac tumor components: case report.

Choriocarcinoma- and yolk sac tumor-like differentiation have rarely been reported in gastric cancers. We report a case of gastric adenocarcinoma, concurrently possessing choriocarcinoma and yolk sac tumor components, of a 74-year-old man. A hemorrhagic, 11 × 8 × 3 cm, tumor with ulceration was located in the body and pre-pylorus of the stomach.

Coexistent poorly-differentiated neuroendocrine cell carcinoma and non-invasive well-differentiated adenocarcinoma in tubulovillous adenoma of the rectum: report of a case.

A 74-years old man was referred to our hospital for treatment of a rectal mass. Colonoscopy revealed villous tumor covering all the lower rectal lumen. Biopsy yielded a diagnosis of adenoma.

Management of oral surgery in patients with hereditary or acquired angioedemas: review and case report.

Angioedemas are a rare but significant event in simple oral surgery because they can cause an acute life-threatening laryngeal edema. We report a case of a tooth extraction in a patient with hereditary angioedema, for which the C1-inhibitor (C1-INH) concentration administered effectively controlled edema during and after extraction. We also review case reports of oral surgery management in patients with hereditary and acquired angioedemas.
