Successful Complete Response of Tumor Thrombus after Combined with Chemotherapy and Irradiation for Ewing Sarcoma.

Pelvic Ewing sarcoma is associated with a worse prognosis. Thromboembolic events are relatively common in pediatric patients with cancers including sarcomas. We have presented a case of Ewing sarcoma arising from the left iliac bone with tumor thrombus of inferior vena cava (IVC) which was obtained complete response by both chemotherapy and irradiation.

Feasibility study of contralateral risk-reducing mastectomy with breast reconstruction for breast cancer patients with BRCA mutations in Japan.

Background: Contralateral risk-reducing mastectomy (CRRM) for breast cancer patients with BRCA mutations has been reported to not only reduce breast cancer incidence but also to improve survival. The National Comprehensive Cancer Network guidelines recommend providing CRRM to women with BRCA mutations who desire CRRM after risk-reduction counseling. However, in Japan, CRRM cannot be performed generally because it is not covered by health insurance.

Role of G protein-regulated inducer of neurite outgrowth 3 (GRIN3) in β-arrestin 2-Akt signaling and dopaminergic behaviors.

The G protein-regulated inducer of neurite growth (GRIN) family has three isoforms (GRIN1-3), which bind to the Gαi/o subfamily of G protein that mediate signal processing via G protein-coupled receptors (GPCRs). Here, we show that GRIN3 is involved in regulation of dopamine-dependent behaviors and is essential for activation of the dopamine receptors (DAR)-β-arrestin signaling cascade. Analysis of functional regions of GRIN3 showed that a di-cysteine motif (Cys751/752) is required for plasma membrane localization.

Proposal for new selection criteria considering pre-transplant muscularity and visceral adiposity in living donor liver transplantation.

Background: The significance of pre-operative body composition has recently attracted much attention in various diseases. However, cut-off values for these parameters remain undetermined, and these factors are not currently included in selection criteria for recipients of living donor liver transplantation (LDLT).

Methods: Using computed tomography of 657 donors for LDLT, skeletal muscle mass, muscle quality, and visceral adiposity were evaluated by using skeletal muscle mass index (SMI), intramuscular adipose tissue content (IMAC), and visceral-to-subcutaneous adipose tissue area ratio (VSR).

Vidarabine, an anti-herpesvirus agent, prevents catecholamine-induced arrhythmias without adverse effect on heart function in mice.

Sympathetic activation causes clinically important arrhythmias including atrial fibrillation (AF) and ventricular tachyarrhythmia. Although the usefulness of β-adrenergic receptor blockade therapy is widely accepted, its multiple critical side effects often prevent its initiation or continuation. The aim of this study is to determine the advantages of vidarabine, an adenylyl cyclase (AC)-targeted anti-sympathetic agent, as an alternative treatment for arrhythmia.

Hyalinizing clear cell carcinoma of the bronchial glands: presentation of three cases and pathological comparisons with salivary gland counterparts and bronchial mucoepidermoid carcinomas.

Hyalinizing clear cell carcinoma of the bronchial glands is a very rare tumor. Since only five reports describing six tumors have been published to date, only a little is known about specific histologic findings and clinical features. Because of its rarity, hyalinizing clear cell carcinoma has not been described in the latest WHO classification of pulmonary tumors yet.

[Esophagogastric Junction Cancer Resection with Bilateral Adrenal Metastasis - A Case Report].

The patient was a 64-year-old man with esophagogastric junction cancer. We performed right thoracotomy-laparotomy for lower esophageal and cardiac gastric resection, D2 lymphadenectomy, and reconstruction of a gastric tube in October 2011. Histopathology confirmed T4aN1M1(LYM), Stage IV cancer(Japanese Classification of Gastric Carcinoma, 14th edition) with R0 resection.

[A Case of Rectal Cancer Presenting with Schistosomiasis Japonica Eggs].

A 87-year-old man had used to live in Shizuoka Prefecture. He got colonoscopy due to melena, and a type 1 tumor about 3 cm was detected in the rectum. He was diagnosed with rectal cancer.

Rikkunshito for Preventing Chemotherapy-Induced Nausea and Vomiting in Lung Cancer Patients: Results from 2 Prospective, Randomized Phase 2 Trials.

The herbal medicine rikkunshito has the potential to improve chemotherapy-induced nausea and vomiting (CINV) by stimulating ghrelin secretion. We aimed to evaluate the efficacy and safety of rikkunshito in preventing CINV for patients with lung cancer. Two separate prospective, randomized, phase II parallel design studies were conducted in patients with lung cancer.

[A Case of Metastatic Carcinoma of Anal Fistula].

A 58-year-old man underwent rectal resection(D2 dissection)for rectal cancer and liver/lung metastases in August 2009. Histopathological findings were Ra, type 2, 70×80mm, tub1>tub2, int, pSI(peritoneum), INF b, ly1, v1, pN1(2/13), pPM0, pDM0, M1a(H1, PUL1), fStage IV . The lung metastasis had disappeared on chest CT after postoperative chemotherapy and we were able to perform radical resection of the liver metastasis by performing hepatectomy twice.

[Sigmoid colon cancer with intussusception prolapsing through the anus treated by elective laparoscopic radical surgery].

An 86-year-old man was brought in ambulance to our hospital because of sudden hematochezia and abdominal pain during defecation. Intestinal prolapse approximately 80mm from the anus and a type 1 tumor 50mm in size on the mucosal surface were detected. The intestinal prolapse was manually repositioned, and the reduction of the intussusception was confirmed by computed tomography (CT).

Validity of Valence Estimation of Dopants in Glasses using XANES Analysis.

X-ray absorption near edge structure (XANES) measurement is one of the most powerful tools for the evaluation of a cation valence state. XANES measurement is sometimes the only available technique for the evaluation of the valence state of a dopant cation, which often occurs in phosphor materials. The validity of the core excitation process should be examined as a basis for understanding the applicability of this technique.

Impact of sarcopenic overweight on the outcomes after living donor liver transplantation.

Background: The effect of body composition disturbances has been recently in focus. Sarcopenic obesity, a co-occurrence of low muscle mass and high body fat was reportedly predictive of high mortality in patients with cirrhosis. However, the impact of the interacting sarcopenia and overweight on the outcomes after liver transplantation is still unclear.

Pneumonectomy in pulmonary metastasis.

Background: The risk of complication following pneumonectomy is high; therefore, the decision to perform pneumonectomy should be carefully evaluated. A retrospective multicenter study of patients with metastatic lung tumors who underwent pneumonectomy was conducted.

Methods: The database from the Metastatic Lung Tumor Study Group of Japan was retrospectively reviewed.

Advancement of magma fragmentation by inhomogeneous bubble distribution.

Decompression times reported in previous studies suggest that thoroughly brittle fragmentation is unlikely in actual explosive volcanic eruptions. What occurs in practice is brittle-like fragmentation, which is defined as the solid-like fracture of a material whose bulk rheological properties are close to those of a fluid. Through laboratory experiments and numerical simulation, the link between the inhomogeneous structure of bubbles and the development of cracks that may lead to brittle-like fragmentation was clearly demonstrated here.

Site-Selective Linear Alkylation of Anilides by Cooperative Nickel/Aluminum Catalysis.

We report meta- and para-selective linear alkylation reactions of anilides with alkenes by nickel/N-heterocyclic carbene (NHC) and aluminum catalysis. With a less bulky NHC, the alkylation reaction of N-methyl-N-phenylcyclohexanecarboxamides proceeded mainly at the meta position. In contrast, a bulky NHC ligand led to the para-selective alkylation of N-sec-alkyl anilides.

Generation of branching ureteric bud tissues from human pluripotent stem cells.

Recent progress in kidney regeneration research is noteworthy. However, the selective and robust differentiation of the ureteric bud (UB), an embryonic renal progenitor, from human pluripotent stem cells (hPSCs) remains to be established. The present study aimed to establish a robust induction method for branching UB tissue from hPSCs towards the creation of renal disease models.

Preoperative low muscle mass has a strong negative effect on pulmonary function in patients undergoing living donor liver transplantation.

Objective: This study investigated the effect of preoperative sarcopenia on cardiopulmonary function in patients undergoing living donor liver transplantation (LDLT).

Methods: A retrospective analysis was performed of 207 patients who underwent LDLT between January 2008 and April 2015. The quantity and quality of skeletal muscle were evaluated by the psoas muscle mass index (PMI) and intramuscular adipose tissue content (IMAC), respectively, using preoperative computed tomography imaging.

Non-traumatic bladder rupture showing less than 10 Hounsfield units of ascites.

Aim: Bladder ruptures are commonly misdiagnosed as gastrointestinal perforations or intestinal ischemia. If a diagnosis is made preoperatively, conservative treatment is a safe and effective option. We evaluated the validity of using the attenuation value of ascites, measured by non-contrast computed tomography (CT), to identify patients with bladder ruptures.

Spontaneous external biliary fistula arising from an intrahepatic duct.

A spontaneous external biliary fistula is most commonly a cholecystocutaneous fistula secondary to acute cholecystitis. A fistula arising from an intrahepatic duct is extremely rare. An 87-year-old man presented with swelling of the epigastric region and right upper quadrant abdomen.

Video-assisted thoracoscopic surgery lobectomy via confronting upside-down monitor setting.

Video-assisted thoracoscopic surgery (VATS) has been widely accepted as a minimally invasive surgery for treatment of early-stage lung cancer. However, various VATS approaches are available. In patients with lung cancer, VATS should achieve not only minimal invasiveness but also safety and oncological clearance.

Indocyanine green fluorescence-navigated thoracoscopic anatomical segmentectomy.

Background: To evaluate the feasibility and efficacy of thoracoscopic anatomical segmentectomy (TS-S) using three-dimensional computed tomography (3D-CT) reconstruction and indocyanine green-fluorescence (ICGF) navigation.

Methods: Twenty TS-S procedures were performed for 15 primary lung cancers and 5 metastatic lung tumors. Preoperatively we evaluated the target segmental pulmonary artery and created a virtual intersegmental plane using 3D-CT reconstruction.

Method to Reduce Long-lived Fission Products by Nuclear Transmutations with Fast Spectrum Reactors.

Transmutation of long-lived fission products (LLFPs: Se, Zr, Tc, Pd, I, and Cs) into short-lived or non-radioactive nuclides by fast neutron spectrum reactors without isotope separation has been proposed as a solution to the problem of radioactive wastes disposal. Despite investigation of many methods, such transmutation remains technologically difficult. To establish an effective and efficient transmutation system, we propose a novel neutron moderator material, yttrium deuteride (YD), to soften the neutron spectrum leaking from the reactor core.

Prognostic Effect of Lymphovascular Invasion on TNM Staging in Stage I Non-Small-cell Lung Cancer.

Introduction: Lymphovascular invasion (LVI) is a known adverse prognostic factor for early-stage non-small-cell lung cancer (NSCLC). Nonetheless, the prognostic effect of LVI on TNM staging of stage I NSCLC remains inconclusive. We thus hypothesized that it might be better to upstage pathologic stage IA NSCLC with LVI to pathologic stage IB NSCLC.
