A 79-year-old man was diagnosed with Stage ⅢB(T4N2M0)adenocarcinoma of the lung, administered. He suddenly developed abdominal pain with muscle guarding and rebound tenderness. An abdominal computed tomography scan revealed a thickened small bowel wall and mesenteric mass, as well as massive ascites and free air.

maintains the balance of primitive endoderm versus epiblast specification during mouse embryonic development by suppression of .

The inner cell mass of the mouse blastocyst gives rise to the pluripotent epiblast (EPI), which forms the embryo proper, and the primitive endoderm (PrE), which forms extra-embryonic yolk sac tissues. All inner cells coexpress lineage markers such as and at embryonic day (E) 3.25, and the EPI and PrE precursor cells eventually segregate to exclusively express and , respectively.

[A Case of Locally Far-Advanced Colon Cancer Resected by Laparoscopic Surgery after Colonic Stent Insertion and Neoadjuvant Chemotherapy].

We report a case of locally far-advanced colon cancer resected by laparoscopic surgery after colonic stent insertion and neoadjuvant chemotherapy. A 71-year-old man with obstructive symptoms was admitted to our hospital in July 2015. CT revealed a sigmoid colon tumor infiltrating the retroperitoneum and small intestine.

Comprehensive Identification of Krüppel-Like Factor Family Members Contributing to the Self-Renewal of Mouse Embryonic Stem Cells and Cellular Reprogramming.

Pluripotency is maintained in mouse embryonic stem (ES) cells and is induced from somatic cells by the activation of appropriate transcriptional regulatory networks. Krüppel-like factor gene family members, such as Klf2, Klf4 and Klf5, have important roles in maintaining the undifferentiated state of mouse ES cells as well as in cellular reprogramming, yet it is not known whether other Klf family members exert self-renewal and reprogramming functions when overexpressed. In this study, we examined whether overexpression of any representative Klf family member, such as Klf1-Klf10, would be sufficient for the self-renewal of mouse ES cells.

[New FP Therapy Was Effective for a Case of Massive Hepatocellular Carcinoma].

A 62 year-old woman was hospitalized with the diagnosis of pneumonia, and a huge mass was recognized in the right lobe of the liver during a CT scan. AFP and PIVKA-Ⅱ were elevated to 101.05 ng/mL and 2,177 mAU/mL.

Effects of treatment with a combination of cardiac rehabilitation and bosentan in patients with pulmonary Langerhans cell histiocytosis associated with pulmonary hypertension.

Pulmonary hypertension (PH), which is classified as group 5 in the clinical classification of PH, is sometimes a complication of Pulmonary langerhans cell histiocytosis (PLCH), and is associated with high mortality. A 36-year-old woman had suffered from severe dyspnea 9 years previously and was diagnosed with PLCH and was on a waiting list for a lung transplant. Right heart failure had been observed and the mean pulmonary artery pressure was over 40 mmHg.

Metachronous bilateral pulmonary metastases from cancer of the ampulla duodeni.

We present a 76-year-old man who underwent two lung resections for metastases originating from cancer of the Ampulla duodeni, 9 years-after pancreaticoduodenectomy with lymphadenectomy. Pancreaticoduodenectomy was performed in 2002; histological examination of the original tumor revealed a stage III tubular adenocarcinoma (pT3, N0, M0). Repetitive lung resection was performed in 2007 (left S8) and 2011 (right S1 and extirpation of a pericardial cyst).

Pulmonary resection after chemoradiotherapy for advanced non-small cell lung cancer: the impact of presurgical radiation therapy.

Purpose: Chemoradiation therapy (CRT) is recommended as standard care for stage III non-small cell lung cancer (NSCLC), but some patients experience local recurrence after the treatment. Surgical resection after CRT involves high surgical risk, but is expected to increase the curability. This study was performed to investigate the impact of presurgical CRT on the postoperative outcome, focusing especially on the effect of radiation therapy.

Totally thoracoscopic surgery and troubleshooting for bleeding in non-small cell lung cancer.

Background: Although accumulating data support the feasibility and efficacy of video-assisted thoracic surgery anatomic resection, few studies have reported on intraoperative complications, such as vessel injury. The purpose of this study was to evaluate intraoperative vessel injury and to analyze troubleshooting.

Methods: Twenty-six of 557 patients with non-small cell lung cancer who underwent thoracoscopic anatomic lung resection were identified as having intraoperative vessel injury between January 2004 and December 2011.

Serum level of HE4 is closely associated with pulmonary adenocarcinoma progression.

The human epididymis 4 (HE4) protein is expressed in the epididymis and respiratory tract. We previously reported that HE4 is also expressed in pulmonary adenocarcinoma. The purpose of this study was to investigate serum levels of HE4 as a biological marker in pulmonary adenocarcinoma.

[Surgical management for lung cancer in less than 1 cm].

Recently, the greater utilization of computed tomography (CT) has led to an increasing proportion of small-sized stage I A lung cancer in less than 1 cm in diameter. However, a treatment strategy for these small-sized lung cancers has not yet been defined. The aim of this study was to investigate surgical outcomes regarding these lung cancers.

Off-the-job training for VATS employing anatomically correct lung models.

We evaluated our simulated major lung resection employing anatomically correct lung models as "off-the-job training" for video-assisted thoracic surgery trainees. A total of 76 surgeons voluntarily participated in our study. They performed video-assisted thoracic surgical lobectomy employing anatomically correct lung models, which are made of sponges so that vessels and bronchi can be cut using usual surgical techniques with typical forceps.

Does pneumothorax occurrence correlate with a change in the weather?

Purpose: There has been speculation that weather changes correlate with the incidence of spontaneous pneumothorax, although this has not been verified. Moreover, there are no significant data available on the meteoropathic pneumothorax in Asia. The aim of this study was to investigate the possible correlation and to compare our results to those of the United States and Europe.

Successful treatment of bronchial anastomotic stenosis with modified Dumon Y-stent insertion in lung transplantation: report of a case.

Bronchial complications owing to airway anastomosis still remain a cause of morbidity and mortality following lung transplantation, and bronchial stenosis is the most common manifestation. Current treatment strategies include endoscopic balloon dilation, laser ablation, and stent insertion. Although a variety of stent types are currently available, it is unclear as to which type of prosthesis is most suitable for post-transplant bronchial complications with regard to the primary effects and long-term outcomes.

Tracheal resection for malignant and benign diseases: surgical results and perioperative considerations.

Purpose: Tracheal surgery is an established treatment for various diseases; however, it is still a potentially challenging procedure. We herein discuss the safety of this procedure with regard to the coordination with airway interventional and anesthetic support.

Methods: A tracheal resection was performed on 18 patients.

Clinical outcome after pulmonary resection for lung cancer patients on hemodialysis.

Background: The number of operations for patients with malignant tumors receiving long-term hemodialysis has been increasing; however, there are only few reports about pulmonary resection for the patients with lung cancer.

Methods: Between 1995 and 2009, 11 hemodialysis patients (6 men, 5 women; mean age, 66.4 years) with non-small cell lung cancer underwent pulmonary resection at our institution.

PPARalpha ligand WY14643 reduced acute rejection after rat lung transplantation with the upregulation of IL-4, IL-10 and TGFbeta mRNA expression.

Background: The peroxisome proliferators-activated receptor-alpha (PPARalpha) is important in lipid metabolism and regulation of inflammation. Recent studies have demonstrated the immunoregulatory effects of PPARalpha. This investigated the immunosuppressive effects of PPARalpha using its ligand, WY14643, on acute lung allograft rejection in a rat model and its mechanism of action.

Krüppel-like factor 5 is essential for blastocyst development and the normal self-renewal of mouse ESCs.

The transcription factor Klf4 has demonstrated activity in the reprogramming of somatic cells to a pluripotent state, but the molecular mechanism of this process remains unknown. It is, therefore, of great interest to understand the functional role of Klf4 and related genes in ESC regulation. Here, we show that homozygous disruption of Klf5 results in the failure of ESC derivation from ICM cells and early embryonic lethality due to an implantation defect.

Association between the expression of chemokine receptors CCR7 and CXCR3, and lymph node metastatic potential in lung adenocarcinoma.

Chemokines and their receptors are essential for leukocyte trafficking, and are also involved in cancer metastasis to specific organs. Although the migration of tumor cells into the lymph nodes is an important aspect of cancer, the processes involved are poorly understood. Chemokine receptors CCR7 and CXCR3 have been shown to play an important role in tumor cell migration and lymph node metastasis.
