A method was recently proposed and experimentally realized for characterizing a quantum state by directly measuring its complex probability amplitudes in a particular basis using so-called weak values. Recently, Vallone and Dequal [Phys. Rev. Lett. 116, 040502 (2016)PRLTAO0031-900710.1103/PhysRevLett.116.040502] showed theoretically that weak measurements are not a necessary condition to determine the weak value. Here, we report a measurement scheme used in a matter-wave interferometric experiment in which the neutron path system's quantum state was characterized via direct measurements, using both strong and weak interactions...

The present study investigated the potential utility of contrast-enhanced abdominal ultrasonography (CEUS), using Sonazoid™, in colorectal cancer (CRC). Three patients were subjected to CEUS with Sonazoid™. Surgical specimens were immunostained for CD31. Numbers of blood vessels positive for CD31 were analyzed in each of five fields at ×400 magnification and averaged to determine blood vessel density. Blood vessel density was compared between non-tumorous and tumorous areas. Prior to the administration of Sonazoid™, CRC was illustrated as irregular-shaped wall thickening...

Intraabdominal lymphangiomas are uncommon; additionally, those affecting the gastrointestinal tract are rare and account for less than 1% of cases. Intussusception caused by a cystic lymphangioma of the small bowel is extremely rare. The patient was a 20-year-old woman who visited our emergency room with a complaint of abdominal pain. A computed tomography image revealed ileo-ileal intussusception with a leading hypovascular mass measuring 1 cm in a diameter. Single-incision laparoscopic-assisted ileal resection was performed...

BACKGROUND: When assessing the cost of transplants in Japan, earlier studies have been limited to case series that investigated inpatient cost alone. Few studies have evaluated total cost, which includes inpatient, outpatient, and pharmaceutical costs, or compared costs before and after transplantation. Using the National Database of Health Insurance Claims and Specific Health Checkups of Japan (NDB), we investigated the total cost of major transplantation and contributing factors. METHODS: We analyzed the cost and complications of patients who underwent a cadaveric renal transplantation (CRT), living renal transplantation (LRT), living-donor liver transplantation (LDLT), allogeneic bone marrow transplantation, autologous bone marrow transplantation, allogeneic peripheral blood stem cell transplantation, or autologous peripheral blood stem cell transplantation (auto-PBSCT) from April 2009 to March 2010...

OBJECTIVES: The techniques and outcomes of outflow reconstruction in living donor liver transplantation (LDLT) using cryopreserved homologous veins at the University of Tokyo Hospital are presented. METHODS: We performed 540 LDLTs from January 1996 to March 2015. Graft types included right liver graft (n = 262), left liver graft (n = 196), left lateral sector graft (n = 53), and posterior sector graft (n = 28). We routinely use cryopreserved homologous vein grafts for the hepatic vein reconstructions to secure the large outflow of the graft...

Among the constituents of the essential nutrient vitamin A, retinol is a potent suppressor of refractory cancer cell growth linked to tumor progression, showing greater efficacy than retinoic acid (RA). However, the mechanisms of retinol action on human refractory cancer are not known well. In the current study, we examined the actions of retinol on proliferation of human gallbladder cancer NOZ C-1 cells. Retinol and RA inhibited the proliferation of human NOZ C-1 cells in dose-dependent manner, while RA was less potent than retinol...

Vitamin A is an essential nutrient that is obtained from the daily diet. The major forms of vitamin A in the body consist of retinol, retinal, retinoic acid (RA), and retinyl esters. Retinal is fundamental for vision and RA is used in clinical therapy of human acute promyelocytic leukemia. The actions of retinol and retinyl palmitate (RP) are not known well. Recently, we found that retinol is a potent anti-proliferative agent against human refractory cancers, including gallbladder cancer, being more effective than RA, while RP was inactive...

Aseptic bone flap resorption, a rare complication after cranioplasty following decompressive craniectomy, is more likely to develop in children. We experienced two cases of aseptic bone flap resorption and identified potential pathophysiological mechanisms through histological findings. In the first case, an 11-year-old girl underwent decompressive craniectomy due to brain swelling with contusion. An autologous bone flap was cryopreserved for four months. Twenty-five months after cranioplasty with autologous bone flap, aseptic bone flap resorption was observed, and cranioplasty was performed with ceramic bone...

An amphoteric ion-exchange resin hardly shrank in 550 and 300 g/L glucose and sodium chloride solutions, respectively; however, the bed packed with a cation-exchange resin shrank considerably. From the distribution coefficients of some saccharides, the swelling pressure of the amphoteric ion-exchange resin was estimated to be 2.0 MPa at 25 °C. The distribution coefficients of glucose, galactose, fructose, and mannose were independent of their concentration and were about 0.621. On the other hand, the apparent distribution coefficients of NaF, NaCl, NaBr, NaI, LiCl, KCl, and CsCl largely depended on concentration...

The aim of this study was to examine the effect of nonprotein respiratory quotient (npRQ), as assessed using indirect calorimetry, on clinical outcomes in patients with liver cirrhosis (LC). A total of 244 LC patients were evaluated in this study. For the univariate analysis, for each continuous variable, the optimal cutoff value that maximized the sum of sensitivity and specificity was selected using receiver operating curve (ROC) analysis for survival. There were 137 men and 107 women with the median (range) age of 67 (25-90) years...

An adolescent obese boy showed late-onset unilateral tibia vara associated with physeal separation (slipped epiphysis) of the lateral proximal tibia and physeal widening of the lateral distal femur. These affected physes showed normal signal intensities by MRI. He was treated with lateral hemiepiphysiodesis of the left proximal tibia and the distal femur using two parallel eight-Plates, and varus deformity rapidly improved postoperatively without recurrence. This is the first case of late-onset tibia vara caused by lateral physeal separation of the proximal tibia...

Many aquatic plants act as biosorbents, removing and recovering metals from the environment. To assess the biosorbent activity of Egeria densa, a submerged freshwater macrophyte, plants were collected monthly from a circular drainage area in Lake Biwa basin and the Mn concentrations of the plants were analyzed. Mn concentrations in these plants were generally above those of terrestrial hyperaccumulators, and were markedly higher in spring and summer than in autumn. Mn concentrations were much lower in plants incubated in hydroponic medium at various pH levels with and without Mn supplementation than in field-collected plants...

BACKGROUND: It is unclear whether health related quality of life (HRQL) may have a predictive value for mortality in idiopathic pulmonary fibrosis (IPF). We investigated the relationship between HRQL assessed using the St. George's Respiratory Questionnaire (SGRQ) and survival time in patients with IPF, and tried to determine a clinical meaningful cut off value to predict poorer survival rates. METHODS: We retrospectively analyzed consecutive patients with IPF who underwent an initial evaluation from May 2007 to December 2012...

OBJECTIVE: Hospitalizations for acute asthma are thought to be highly preventable through the use of efficacious medications, though many patients have poor metered-dose inhaler (MDI) technique, lessening these medications' real-world effectiveness. Teaching MDI technique during hospitalization may therefore lead to improved outcomes. However, MDIs may be underutilized to deliver short-acting β-agonists in the inpatient setting, despite equivalent efficacy to nebulizer delivery. We sought to characterize delivery methods of short-acting beta-agonist (SABA) therapy among hospitalized patients with acute asthma to understand if there are missed opportunities for self-management education...

For neuroendocrine tumor G1, local resection is one of the primary treatment options. Endoscopic submucosal dissection has been proven to ensure complete resection with sufficient margins. However, duodenal endoscopic submucosal dissection has a high risk of duodenal perforation because of the thin duodenal wall and poor endoscopic maneuverability. During laparoscopic dissection, suturing can resolve perforation. Therefore, laparoscopic-endoscopic cooperative surgery (LECS) can ensure complete resection with a minimal margin to prevent stenosis, and suturing can resolve perforation...

PURPOSE: To observe choroidal blood vessels in cases sharply demarcated with retinal pigment epithelium (RPE) atrophy at the macular area using en-face optical coherence tomography angiography (OCTA) and standard en-face optical coherence tomography (OCT). METHODS: The retrospective study included 12 eyes (8 patients; 5 men, 3 women; average age, 64.3 years) with RPE atrophy seen by ophthalmoscopy. The macular areas with normal and atrophic RPE sections were examined using en-face OCTA with an 840-nm light source (RTVue XR Avanti; Optovue Inc), which system can obtain standard en-face OCT images at identical areas...

To investigate how motor sensation facilitates learning, we used a sensory-motor association task to determine whether the sensation induced by forced movements contributes to performance improvements in rats. The rats were trained to respond to a tactile stimulus (an air puff) by releasing a lever pressed by the stimulated (compatible condition) or nonstimulated (incompatible condition) forepaw. When error rates fell below 15%, the compatibility condition was changed (reversal learning). An error trial was followed by a lever activation trial in which a lever on the correct or the incorrect response side was automatically elevated at a preset time of 120, 220, 320, or 420 ms after tactile stimulation...

We herein report a case of acute cholangitis and bacteremia caused by a commensal Neisseria species, Neisseria subflava, in an 82-year-old man with cholangiocarcinoma. Emergency endoscopic nasobiliary drainage and cefoperazone/sulbactam therapy were effective. Gram negative coccobacilli were isolated from both blood and bile cultures on 5% sheep blood agar. The isolate was identified as N.subflava biovar perflava by mass spectrometry, a sequence analysis of the 16S rRNA, and biochemical testing. Although biliary infections due to commensal Neisseria are extremely rare, this case demonstrates the possibility of its occurrence in patients undergoing bile duct treatment...

Late-onset amyloidogenic transthyretin (ATTR) type familial amyloid polyneuropathy (FAP) shows features distinct from those of early-onset hereditary ATTR type FAP. We herein describe an asymptomatic 68-year-old man with late-onset ATTR type FAP whose serial annual electrocardiograms demonstrated progressive left bundle branch block. Latent but severe cardiac involvement seems to be one feature of late-onset ATTR type FAP, similar to senile systemic amyloidosis (SSA). Early differential diagnosis of late-onset ATTR type FAP from SSA is important because, currently, only the former has new therapeutic options available in Japan...
