Both Li2CO3-coated nickel particles and fast firing technique were utilized in the manufacturing of MLCCs. They preserved the conductivity of Ni electrodes and provided the possibility of sintering the devices in oxidizing atmospheres. By using our method, the partial pressure of oxygen increase from 10-10 atm in conventional methods to 10-4 atm. The oxidizing atmosphere reduced the oxygen vacancy concentration as illustrated by the color change of the samples, and the results of EELS (electron energy loss spectroscopy)...

The quantum thermal bath (QTB) has been presented as an alternative to path-integral based methods to introduce nuclear quantum effects in molecular dynamics simulations. The method has proved to be efficient, yielding accurate results for various systems. However, the QTB method is prone to zero-point energy leakage (ZPEL) in highly anharmonic systems. This is a well known problem in methods based on classical trajectories where part of the energy of the high frequency modes is transferred to the low frequency modes leading to a wrong energy distribution...

Diabetic retinopathy is a progressive microvascular disease that leads to increased vessel permeability, retinal ischemia, and retinal neovascularization. Optical coherence tomography angiography (OCTA) is a novel angiography technique that has the capability to advance our understanding of diabetic eye disease by providing high-resolution images of retinal and choroidal microvasculature blood flow and structure. Using OCTA, the vascular changes of diabetic retinopathy including microaneurysms, retinal non-perfusion, intraretinal microvascular abnormalities, and neovascularization can be clearly visualized...

Aim: Advanced atherosclerosis increases inflammation and stroke risk in the cerebral vasculature. Exercise is known to improve cardio-metabolic profiles when associated with a caloric restriction, but it remains debated whether it is still beneficial without the dietary control. The aim of this study was to determine both the peripheral and central effects of exercise training combined with a cholesterol-rich diet given ad libitum in old ApoE(-/-) mice. Methods: Forty-five-weeks old obese ApoE(-/-) mice fed with a high cholesterol diet ad libitum were divided into Exercise-trained (EX; running wheel free access) and Sedentary (SED) groups...

A Lagrangian model which simulates the dispersion of (137)Cs in the North Atlantic has been developed. The model includes water/sediment interactions. It has been tested comparing calculated and measured (137)Cs concentrations in water and sediments of the European Shelf resulting after the releases from the nuclear fuel reprocessing plants of Sellafield and La Hague. Some additional numerical experiments have been carried out. First, the redissolution of (137)Cs from contaminated sediments after the reduction in releases from the reprocessing plants has been studied...

In this study, mango fruit were pre-treated with low-temperature conditioning (LTC) at 12°C for 24h, followed by refrigeration at 5°C for 25days before removal to ambient temperature (25°C) to investigate the effects and possible mechanisms of LTC on chilling injury (CI). The results showed that LTC effectively suppressed the development of CI in mango fruit, accelerated softening, and increased the soluble solids and proline content. Furthermore, LTC reduced electrolyte leakage, and levels of malondialdehyde, O2(-) and H2O2, maintaining membrane integrity...

BACKGROUND: Leak rates of over 5% following anastomoses between the ileum and colon continue to be reported in large series and are associated with substantial morbidity and with mortality rates of 10-20%. In 1994, we began performing circumferentially oversewn inverted stapled anastomoses in patients undergoing ileo-colic anastomoses or ileostomy closure. It has become increasingly apparent that this method is associated with a low risk of leakage, which we should report. METHODS: The anastomotic technique described was used in all patients undergoing ileo-colic anastomosis or closure of ileostomy by surgeon 1 (1994-2015) and in all ileo-colic anastomoses by surgeon 2 (2007-2015)...

Tetrandrine (TET) is a bis-benzylisoquinoline alkaloid, which is isolated from a Chinese medicinal herb with antioxidant and anti-inflammatory activities. In this study, we investigated the effects of TET on oxygen-glucose-serum deprivation/reoxygenation (OGSD/R)-induced injury in rat spinal cord astrocytes, which mimics hypoxic/ischemic conditions in vivo. MTT and LDH assays indicated that cell viability was distinctly reduced and LDH leakage was elevated after OGSD/R exposure, which were dose-dependently reversed by pretreatment with TET (0...

BACKGROUND: The effect of anastomotic leakage on oncological outcomes after total mesorectal excision (TME) is controversial. This study aimed to assess the influence of symptomatic and asymptomatic anastomotic leakage on oncological outcomes after laparoscopic TME. METHODS: All patients who underwent restorative laparoscopic TME for rectal adenocarcinoma with curative intent from 2005 to 2014 were identified from an institutional database. Asymptomatic anastomotic leakage was defined by CT performed systematically 4-8 weeks after rectal surgery, with no relevant clinical symptoms or laboratory examination findings during the postoperative course...

CONTEXT: Damage to the auditory system by loud sounds can be avoided by hearing protection devices (HPDs) such as earmuffs, earplugs, or both for maximum attenuation. However, the attenuation can be limited by air conduction (AC) leakage around the earplugs and earmuffs by the occlusion effect (OE) and by skull vibrations initiating bone conduction (BC). AIMS: To assess maximum attenuation by HPDs and possible flanking pathways to the inner ear. SUBJECTS AND METHODS: AC attenuation and resulting thresholds were assessed using the real ear attenuation at threshold (REAT) procedure on 15 normal-hearing participants in four free-field conditions: (a) unprotected ears, (b) ears covered with earmuffs, (c) ears blocked with deeply inserted customized earplugs, and (d) ears blocked with both earplugs and earmuffs...

Previous investigations on rare-earth oxides (REOs) reveal their high possibility as dielectric films in electronic devices, while complicated physical methods impede their developments and applications. Herein, we report a facile route to fabricate 16 REOs thin insulating films through a general solution process and their applications in low-voltage thin-film transistors as dielectrics. The formation and properties of REOs thin films are analyzed by atomic force microscopy (AFM), X-ray diffraction (XRD), spectroscopic ellipsometry, water contact angle measurement, X-ray photoemission spectroscopy (XPS) and electrical characterizations, respectively...

We present a case of a 41-year-old man with symptomatic pulmonary cement embolism following percutaneous vertebral augmentation, which was successfully retrieved via a percutaneous endovascular approach, a novel technique with only two prior cases reported. Cement leakage, including venous embolization of cement into the cardiopulmonary circulation, is a known potential complication following percutaneous kyphoplasty and vertebroplasty. While many patients with pulmonary cement embolism are asymptomatic and likely go undiagnosed, others experience respiratory distress and hemodynamic compromise requiring surgical and medical intervention...

Leaf senescence is a typical symptom in plants exposed to dark and may be regulated by plant growth regulators. The objective of this study was to determine whether exogenous application of melatonin (N-acetyl-5-methoxytryptamine) suppresses dark-induced leaf senescence and the effects of melatonin on reactive oxygen species (ROS) scavenging system and chlorophyll degradation pathway in perennial grass species. Mature perennial ryegrass (Lolium perenne L. cv. 'Pinnacle') leaves were excised and incubated in 3 mM 2-(N-morpholino) ethanesulfonic buffer (pH 5...

An 81-year-old man underwent total gastrectomy with Roux-en-Y reconstruction for cardiac cancer in our department. He developed high fever on postoperative day 3, and pathological examination showed WBC and CRP level of 12,000/mL and 29.983mg/dL, respectively. A diagnosis of anastomotic leakage was confirmed using enhanced abdominal CT scanning that demonstrated free air around the esophagojejunalanastomosis after totalgastrectomy. The drainage tube was replaced by a 12 Fr sump tube because of leakage on postoperative day 10...
