Published: December 2013

AbstractA large part of the southeastern Tibetan Plateau (TP) is characterized by low‐relief surfaces at high elevations (>3.5 km). The origin of these landscapes and their geodynamic implications with regard to evolution of the southeastern TP has been the subject of considerable debate. Focusing on this topic, this study utilizes fission track and (U‐Th)/He thermochronology to reconstruct the thermal history of the Late Triassic Daocheng granite, on which a low‐relief high‐elevation landscape has developed. Results suggest that the plateau surface experienced widespread Late Jurassic to Early Cretaceous cooling (at a rate of ~1–2°C/Ma), followed by minimal regional cooling (~0.3°C/Ma) and Early Miocene enhanced cooling (~2–3°C/Ma) along deep valleys at the southern edge of the landscape. Given the subdued Late Jurassic to Early Cretaceous crustal deformation in the study area, we relate the coeval cooling to crustal refrigeration and exhumation triggered by northward subduction of the Meso‐Tethys Ocean along the Bangong suture. Subsequent Late Cretaceous to Cenozoic minimal cooling supports arguments for the formation of a low‐elevation landform prior to uplift of the southeastern TP. The enhanced cooling commenced at the Early Miocene (~15–22 Ma) along deep valleys and heralded the onset of river incision and surface uplift of the southeastern TP. This finding does not support previous proposals claiming that high elevations of the southeastern TP were formed in Late Miocene time resulting from lower crustal flow but rather supports a model highlighting continental subduction and extrusion along the large Tanggula‐Yushu‐Batang‐Red River fault system.

AbstractBroadband magnetotelluric (MT) measurements were conducted in 2010 and 2011 in the vicinity of Shinmoe‐dake Volcano in the Kirishima volcano group, Japan, where sub‐Plinian eruptions took place 3 times during 26–27 January 2011. By combining the new observations with previous MT data, it is found that an anomalous phase in excess of 90° is commonly observed in the northern sector of the Kirishima volcano group. Because the anomalous phase is not explained by 1‐D or 2‐D structure with isotropic resistivity media, 3‐D inversions were performed. By applying small errors to the anomalous phase, we successfully estimated a 3‐D resistivity structure that explains not only the normal data but also the anomalous phase data. The final model shows a vertical conductor that is located between a deep‐seated conductive body (at a depth greater than 10 km) and a shallow conductive layer. By applying the findings of geophysical and petrological studies of the 2011 sub‐Plinian eruptions, we infer that the subvertical conductor represents a zone of hydrothermal aqueous fluids at temperatures over 400°C, in which a magma pathway (interconnected melt) is partially and occasionally formed before magmatic eruptions. To the north of the deep conductor, earthquake swarms occurred from 1968 to 1969, suggesting that these earthquakes were caused by volcanic fluids.

Published: December 2013

SignificanceA new generation of double dielectric barrier discharge (DDBD) reactor featured by a metal powder (MP) high voltage electrode is presented. The MP high voltage electrode not only has excellent homogeneous discharge performance but also has the advantage of without regular maintenance. Therefore, the MP‐DDBD reactor was proved to be suitable for the uninterrupted and safe synthesis of high purity H2O2 aqueous solution with up to 65 wt % concentration from the H2/O2 mixture. The scale‐up synthesis of H2O2 was successfully attempted in an integrated device based on the MP‐DDBD reactor. The future practical H2O2 synthesizer based on the MP‐DDBD reactor will be small and movable, and therefore, be convenient to supply high purity H2O2 on site for small scale users like semiconductor industry. © 2013 American Institute of Chemical Engineers AIChE J 60: 415–419, 2014

Published: December 2013

ABSTRACTHigh electrochemical active free‐standing multiwalled carbon nanotube (MWNT) films have been synthesized from aniline oligomer functionalized MWNTs (MWNT‐AO), by using filtration of the acidic phosphate ester (APE) doped MWNT‐AO dispersions. The homogeneously distributed MWNTs endowed APE/MWNT films automatically releasing from the filter membrane. The sheet resistivity of MWNT‐AO (850 Ω sq−1) showed a lower value than that of carboxyl MWNTs (1273 Ω sq−1), due to the doping effect of MWNT on aniline oligomer, confirmed by the N1s X‐ray photoelectron spectrum. However, it showed a higher sheet resistivity value of 1526 Ω sq−1 after further doped by APE, because of the presence of unreacted dopant. After removing the residual insulating dopant by the vacuum filtration, the resultant APE/MWNT films showed the sheet resistivity value as low as 131 Ω sq−1. Thermogravimetric analysis showed that the MWNT loading in the film can be over than 77%, which showed the specific capacitance as high as 249 F g−1. © 2013 Wiley Periodicals, Inc. J. Appl. Polym.

Published: December 2013

ObjectiveTotal hip arthroplasty (THA) and total knee arthroplasty (TKA) are effective procedures for patients with moderate‐to‐severe osteoarthritis. Mortality rates after THA and TKA may have changed because of new surgical techniques, improvement of peri‐ and postoperative care, and performance of surgery in older patients having multiple comorbidities. However, data on secular mortality trends are scarce. We undertook this study to evaluate mortality patterns between 1989 and 2007 in patients undergoing elective THA and TKA.MethodsIn a Danish retrospective nationwide cohort study, 71,812 patients who underwent THA and 40,642 patients who underwent TKA were identified between January 1989 and December 2007. All‐cause and disease‐specific mortality was assessed, stratified by calendar periods. Using Cox proportional hazards models, relative risks (RRs) of mortality were calculated between different calendar periods, adjusted for age, sex, and comorbid diseases.ResultsSince the early 1990s, short‐term survival following elective THA and TKA has greatly improved. Compared with the period between 1989 and 1991, 60‐day mortality rates between 2004 and 2007 were substantially lower for patients undergoing THA (RR 0.40, 95% confidence interval [95% CI] 0.28–0.58) and for patients undergoing TKA (RR 0.37, 95% CI 0.21–0.67). This trend was far superior to what was seen in the general population. The decrease in mortality was greatest for deaths from myocardial infarction, venous thromboembolism, pneumonia, and stroke. Patients tended to have more presurgical comorbidity over time, and the duration of hospital stay was roughly halved.ConclusionMortality rates following elective THA and TKA have decreased substantially since the early 1990s, despite patients having more presurgical comorbidity. These findings are reassuring for patients undergoing elective THA or TKA.

Published: December 2013

ObjectiveTo identify the optimal exercise program, characterized by type and intensity of exercise, length of program, duration of individual supervised sessions, and number of sessions per week, for reducing pain and patient‐reported disability in knee osteoarthritis (OA).MethodsA systematic review and meta‐analysis of randomized controlled trials were performed. Standardized mean differences (SMDs) were combined using a random‐effects model. Study‐level covariates were applied in meta‐regression analyses in order to reduce between‐study heterogeneity.ResultsForty‐eight trials were included. Similar effects in reducing pain were found for aerobic, resistance, and performance exercise (SMD 0.67, 0.62, and 0.48, respectively; P = 0.733). These single‐type exercise programs were more efficacious than programs that included different exercise types (SMD 0.61 versus 0.16; P < 0.001). The effect of aerobic exercise on pain relief increased with an increased number of supervised sessions (slope 0.022 [95% confidence interval 0.002, 0.043]). More pain reduction occurred with quadriceps‐specific exercise than with lower limb exercise (SMD 0.85 versus 0.39; P = 0.005) and when supervised exercise was performed at least 3 times a week (SMD 0.68 versus 0.41; P = 0.017). No impact of intensity, duration of individual sessions, or patient characteristics was found. Similar results were found for the effect on patient‐reported disability.ConclusionOptimal exercise programs for knee OA should have one aim and focus on improving aerobic capacity, quadriceps muscle strength, or lower extremity performance. For best results, the program should be supervised and carried out 3 times a week. Such programs have a similar effect regardless of patient characteristics, including radiographic severity and baseline pain.
3D shape retrieval using viewpoint information‐theoretic measures

Published: December 2013

AbstractIn this paper, we present an information‐theoretic framework to compute the shape similarity between 3D polygonal models. Given a 3D model, an information channel between a sphere of viewpoints around the model and its polygonal mesh is defined to compute the specific information associated with each viewpoint. The obtained information sphere can be seen as a shape descriptor of the model. Then, given two models, their similarity is obtained by performing a registration process between the corresponding information spheres. The distance between the information histograms is also defined as a coarse measure of similarity, as well as the scalar value given by the mutual information of the channel. The performance of all these measures is tested using the Princeton Shape Benchmark database. Copyright © 2013 John Wiley & Sons, Ltd.

Abstract(+)‐Catechin is a type of catechin present in large amounts in açaí fruits and cocoa seeds. Besides its antioxidant and anti‐inflammatory activities, little is known about its effects in the liver, especially during hepatic fibrosis. We report here the effects of (+)‐catechin on hepatic stellate cells. (+)‐Catechin induced quiescent phenotype in GRX cells, along with an increase in lipid droplets. Proliferator‐activated receptor γ mRNA expression was upregulated, whereas type I collagen mRNA expression was downregulated. Pro‐inflammatory cytokines were not influenced by (+)‐catechin, whereas the levels of interleukin 10 were significantly increased. The data provide evidence that (+)‐catechin can reduce hepatic stellate cell activation.
Structure‐Based and Fragment‐Based GPCR Drug Discovery
Authors: Andrews Stephen P. , Brown Giles A. , Christopher John A. 
Published: December 2013

AbstractG protein‐coupled receptors (GPCRs) are an important family of membrane proteins; historically, drug discovery in this target class has been fruitful, with many of the world’s top‐selling drugs being GPCR modulators. Until recently, the modern techniques of structure‐ and fragment‐based drug discovery had not been fully applied to GPCRs, primarily because of the instability of these proteins when isolated from their cell membrane environments. Recent advances in receptor stabilisation have facilitated major advances in GPCR structural biology over the past six years, with 21 new receptor targets successfully crystallised with one or more ligands. The dramatic increase in GPCR structural information has yielded an increased use of structure‐based methods for hit identification and progression, which are reviewed herein. Additionally, a number of fragment‐based drug discovery techniques have been validated for use with GPCRs in recent years; these approaches and their use in hit identification are reviewed.
Sensing‐throughput tradeoff for cooperative multiple‐input single‐output cognitive radio
Authors: Liu Xin , Jing Qingfeng , Jia Yun , Zhong Weizhi , Guan Yong Liang 
Published: December 2013

SummaryIn this paper, we propose a new cooperative multiple‐input single‐output (MISO) cognitive radio (CR) system, which can use some of the antennas to transmit its data and the others to help to transmit the data of the primary user (PU) by performing cooperative communication if the presence of the PU is detected through the cooperative spectrum sensing. A new cooperative sensing‐throughput tradeoff model is proposed, which maximizes the aggregate rate of the CR by jointly optimizing sensing time and spatial sub‐channel power, subject to the constraints of the aggregate rate of the PU, the false alarm and detection probabilities, the aggregate interference to the PU and the aggregate power of the CR. Simulation results show that compared with the conventional scheme, the proposed cooperative scheme can achieve the larger aggregate rate of the CR, while keeping the aggregate rate of the PU invariable with the increasing of the interference.

Lipid and sensory quality of canned Atlantic salmon (Salmo salar): Effect of the use of different seaweed extracts as covering liquids
Authors: Ortiz Jaime , Vivanco Juan P. , Aubourg Santiago P. 
Published: December 2013

The addition of natural compounds as additives in fish products is increasingly important to prevent or delay their deterioration. Nowadays, most of the additives used on seafood are synthetic, and their safety is being increasingly questioned. The aim of this research was to compare the effects of the addition of different seaweeds extracts on lipid and sensory quality parameters of canned Atlantic salmon (Salmo salar) muscle. For this purpose, four different seaweeds extracts were tested: cochayuyo, sea lettuce, ulte, and red luche as covering liquids against a standard, without seaweed extract. For each sampling day, three cans from each treatment were analyzed periodically, up to reach 140 days of storage at 40°C. The parameters that were measured are: fatty acids content (saturated, monounsaturated, and polyunsaturated), polyene index (PI), peroxide value (PV), p‐anisidine value (pAV), astaxanthin content (AX), total tocopherols content, total volatile basic nitrogen (TVB‐N), and sensory indicators of “characteristic flavor” and “rancid odor.” All chemical parameters measured (fatty acids, PI, PV, pAV, AX, total tocopherols, and TVB‐N) showed significant differences between all treatments and throughout storage time. Sensory parameters were not significantly different between canned salmons packed with different covering liquids, and they were always within acceptable limits.Practical applications: The results obtained in this research show the possibility of the use of seaweeds as an alternative source of natural antioxidants in fatty fish canning. Next studies on the use of seaweeds to help in fish and seafood preservation should be focused on the use of mixtures of seaweeds as protective extracts. The results indicate that it is possible to obtain advantages in the preservation of canned salmon, based on the use of some seaweed extracts as covering liquid, which can help inhibit lipid peroxidation.

Published: December 2013

Tridocosahexaenoyl glycerol (tri‐DHA) has been identified and purified from the commercial oil DHASCO®, a natural and renewable source of DHA with 7.48 wt% of tri‐DHA, by means of a gravimetric normal‐phase chromatographic column and silver nitrate‐silica gel as stationary phase. This method allows the purification of a highly enriched tri‐DHA fraction from DHASCO® (84.4% of the total tri‐DHA contained in DHASCO®), and DHA accounting for 79.8% of the total fatty acids of the purified fraction. Subsequently, the whole process was scaled up to 10 times with satisfactory results.Practical applications: This work was conducted to obtain a valuable form of DHA from a natural resource. The whole process, in which the use of unsafe solvents is avoided, has been designed to allow the potential use of the DHA‐enriched fraction in the food and pharmaceutical industries as nutritional supplement, as well as for use in laboratory research using animal models.

Binge Eating, Binge Eating Disorder and Loss of Control Eating: Effects on Weight Outcomes after Bariatric Surgery
Authors: Meany Gavin , Conceição Eva , Mitchell James E. 
Published: December 2013

AbstractThere is increasing evidence that patients who have problems with binge eating (BE) or BE disorder (BED) are quite common among the severely obese, including bariatric surgery candidates. The literature suggests that in many cases such eating behaviours improve after bariatric surgery, although this is not uniformly true. The current paper reviews the data on the development of BE, BED and loss of control (LOC) eating after bariatric surgery and the impact of these problems on long‐term weight outcome. A search was made of various databases regarding evidence of BE, BED and LOC eating post‐operatively in bariatric surgery patients. The data extracted from the literature suggests that 15 research studies have now examined this question. Fourteen of the available 15 studies suggest that the development of problems with BE, BED or LOC eating post‐bariatric surgery is associated with less weight loss and/or more weight regain post‐bariatric surgery. These data suggests that it is important to identify individuals at high risk for these problems, to follow them post‐operatively, and, if appropriate interventions can be developed if such behaviours occur in order to maximize weight loss outcomes.

AbstractBackgroundThis study investigated the effects of 2 different swallowing exercise regimens performed during radiation therapy with/without chemotherapy on swallowing function.MethodsFifty patients were recruited prospectively to 2 groups (the exercise group, n = 26 and the repetitive swallow group, n = 24). Functional Oral Intake Scale (FOIS) scores and percutaneous endoscopic gastrostomy (PEG) placements were compared at posttreatment and at 3 months.ResultsThe exercise group eliminated significantly more PEG tubes at 3 months posttreatment compared to the swallow group (16% vs 50%). Among patients who received both radiation and chemotherapy, the exercise group had significantly less PEG tubes immediately posttreatment as well as 3 months posttreatment (35% and 10%), compared to the swallow group (69% and 50%).ConclusionFindings indicate significant benefits of the exercise group's exercise regimen in reducing PEG dependence and oral intake difficulties. © 2014 Wiley Periodicals, Inc.

Published: December 2013

AbstractBackgroundThe role of contemporary radiotherapy (RT) has not yet been elucidated, mainly because of the low incidence of cervical esophageal cancer. The purpose of this study was to analyze the outcome in patients with cervical esophageal cancer treated with definitive RT.MethodsA total of 115 patients with cervical esophageal cancer treated with definitive RT during January 2001 through April 2012 in our center were analyzed. Eighty patients received RT alone and 35 patients received concurrent chemoradiotherapy with cisplatin administered either weekly (30 mg/m2) or every 3 weeks (80 mg/m2).ResultsThe median follow‐up time was 17.1 months. For all patients, the overall 2‐year local failure‐free survival (LFFS), regional failure‐free survival (RFFS), distant failure‐free survival (DFFS), and overall survival (OS) rate was 68.3%, 83.3%, 75.7%, and 47.6%, respectively.ConclusionDefinitive RT accomplished a satisfactory local control rate and contributed to organ preservation for patients with cervical esophageal cancer. © 2014 Wiley Periodicals, Inc.
