AbstractWe evaluated coracoacromial ligament (CAL) displacement during motion in shoulders with supraspinatus tendon tears by dynamic ultrasonography (US). Twenty subjects with unilateral, full‐thickness supraspinatus tendon tears (SST group) and 20 subjects with intact supraspinatus tendons (control group) underwent dynamic US. The CAL displacement in their bilateral shoulders was measured in the transverse US view during passive and active shoulder abduction and internal rotation (SAIR). In the SST group, the CAL displacement was significantly greater in the affected shoulders than in the intact ones (1.9 mm ± 0.8 mm vs. 1.5 mm ± 0.5 mm, p = 0.01) during passive SAIR, but was not significantly different between the shoulders (1.7 mm ± 0.7 mm vs. 1.7 mm ± 0.4 mm, p = 0.81) during active SAIR. In the control group, no difference in the CAL displacement between the shoulders was noted during passive and active SAIR. Thus, dynamic US revealed greater CAL displacement in shoulders with supraspinatus tendon tears than in intact ones during passive SAIR. Dynamic US may help to detect abnormal kinematics in shoulders with such injury. © 2012 Orthopaedic Research Society. Published by Wiley Periodicals, Inc. J Orthop Res 30:1430–1434, 2012

Published: February 2012

AbstractRoot active uptake and remobilization of boron (B) have been accepted as mechanisms contributing to nutrient efficiency under low supply of boron. Here, we examined the existence of these mechanisms in eggplant (Solanum melongena L.) supplied either with luxury (100 μM, B+) or low (7.5 μM, B–) B in the growth medium via semihydroponic cultivation. Boron treatment was marginally not limiting growth thus avoiding side‐effects and impairment of acclimation mechanisms of plants. The induction of a B‐concentrating mechanism was evident in the roots as B concentration in the xylem sap was only decreased by 23% in B– compared to B+ plants, i.e., B– roots concentrated B by a factor of 2.7 relative to the external solution. Leaf B concentration in the B– treatment decreased by 33% and 40% in young fully expanded and mature leaves, respectively. Larger differences were observed in the soluble B fraction that decreased by 65% in mature leaves. However, both total and soluble B concentrations in developing leaves were almost equal for both treatments exhibiting a pattern commonly observed in B‐remobilizing plants. On the other hand, amounts of B export in the phloem sap were small compared to other species in which B is highly mobile. The B export rate from source leaves was slightly increased under low B supply while that of sucrose was not affected. We conclude that the root concentrating mechanism contributes to the alleviation of B deficiency in eggplant under low B supply while B remobilization may also contribute to a lower degree.

AbstractLower P‐input levels in organic than conventional farming can decrease soil total and available P, which can potentially be resupplied from soil organic P. We studied the effect of 30 y of conventional and organic farming on soil P forms, focussing especially on organic P. Soil samples (0–20 cm) were taken in a field experiment with a nonfertilized control, two organic systems receiving P inputs as animal manure, and two conventional systems receiving only mineral P or mineral P and manure. Soils were analyzed for total, inorganic, organic, and microbial P, by sequential P fractionation and by enzyme additions to alkaline soil extracts. Samples taken prior to starting the experiment were also analyzed. Average annual P balances ranged from –20 to +5 kg ha–1. For systems with a negative balance, labile and moderately labile inorganic P fractions decreased, while organic and stable inorganic P fractions were hardly affected. Similar quantities and proportions of organic P extracted with NaOH‐EDTA were hydrolyzed in all soils after addition of an acid phosphatase, a nuclease, and a phytase, and enzyme‐stable organic P was also similar among soils. Thus, neither sequential fractionation nor enzyme addition to alkaline soil extracts showed an effect of the type of applied P (manure vs. mineral) on organic P, suggesting that organic P from manure has largely been mineralized. Thus far, we have no indication that the greater microbial activity of the organic systems resulted in a use of stable P forms.
Health effects of an organic diet—consumer experiences in the Netherlands
Authors: van de Vijver Lucy PL , van Vliet Marja ET 
Published: February 2012

AbstractBACKGROUND: Health is one of the main reasons for consumers to buy organic; however, scientific evidence for a health effect is still limited. The aim of this study was to investigate the perceived health effects experienced by consumers of organic food using a free access online questionnaire.RESULTS: A total of 566 respondents participated, of whom 30% reported no health effects. The other respondents reported better general health, including feeling more energetic and having better resistance to illness (70%), a positive effect on mental well‐being (30%), improved stomach and bowel function (24%), improved condition of skin, hair and/or nails (19%), fewer allergic complaints (14%) and improved satiety (14%). Furthermore, it was found that the switch to organic food was often accompanied by the use of more freshly prepared foods and other lifestyle changes.CONCLUSION: This research provided insight into the experienced health effects of consumers of organic food. Although the study design does not permit direct conclusions on health effects of organic food, the results can serve as a basis for the generation of new hypotheses.

Nitrogen availability drives the effect of Glomus intraradices on the growth of strawberry (Fragaria x ananassa Duch.) plants
Authors: Castellanos‐Morales Vilma , Villegas‐Moreno Javier , Vierheilig Horst , Cárdenas‐Navarro Raúl 
Published: February 2012

AbstractBACKGROUND: On the one hand, the critical nitrogen (N) content curve allows the minimal N content necessary for maximum growth rate at any stage of crop development to be predicted. On the other hand, arbuscular mycorrhizal fungi (AMF) transfer N from the soil to the plants and its growth and activity depends on the availability of soil N. Our objective was to investigate how the availability of N in the soil affects growth and the accumulation of N in inoculated strawberry plants. Root colonisation, dry matter accumulation and the critical N% curve were studied during growth of inoculated and non‐inoculated strawberry plants grown at several N levels.RESULTS: (1) The increase in the availability of N augmented root colonisation by AMF. (2) The effect of AMF on plant growth depended on N availability and the plant developmental status. (3) The critical %N curves were fitted by the following equations: %N = 2.81× (DM)−0.21 (r2 = 0.81) and %N = 2.89× (DM)−0.32 (r2 = 0.80) for inoculated and non‐inoculated plants, respectively (where DM is the weight of leaf dry matter, in g plant−1).CONCLUSION: N availability was a key factor for root colonisation by AMF and for its contribution to plant growth. The patterns of the critical %N curves suggest that AMF modified the photosynthetic N use efficiency. Copyright © 2012 Society of Chemical Industry

AbstractRecent improvements in the survival of patients after esophagectomy have led to an increase in the occurrence of gastric tube cancer (GTC). Total resection of the gastric tube with lymphadenectomy is a standard and reliable treatment for GTC, but problems may arise during or after surgery, such as laryngeal nerve injury, reduced selection of organs for reconstruction, and impaired swallowing function. We recently performed a less invasive procedure, subtotal gastrectomy with preservation of the upper region of the gastric tube, in two patients. In these patients, blood supply to the gastric tube was evaluated by indocyanine green fluorescence imaging. Blood flow was confirmed as passing from the remnant esophagus to the upper region of the gastric tube through the esophago‐gastric anastomotic site by indocyanine green fluorescence imaging. Therefore, we resected the gastric tube while preserving the upper region of the gastric tube. There was no necrosis of the remnant gastric tube or anastomotic leakage postoperatively, and postoperative swallowing and eating functions were quite good in both patients. In summary, subtotal gastrectomy as a treatment for GTC is potentially safe, curative, and beneficial for the patient's quality of life. J. Surg.

AbstractBackground and ObjectivesIn metastatic colorectal cancer, v‐Ki‐ras2 Kirsten rat sarcoma viral oncogene homolog (KRAS) is a predictive biomarker for anti‐epidermal growth factor receptor (EGFR) treatment and V‐raf murine sarcoma viral oncogene homolog B1 (BRAF) is a prognostic biomarker. We aimed to determine the impact of KRAS and BRAF mutation as determined from liver metastases specimens on overall survival (OS) in patients following colorectal liver metastasectomy.MethodsLiver metastases specimens (n = 292) obtained from patients after liver metastasectomy were used to determine the KRAS/BRAF genotype. Associations between clinicopathological parameters and KRAS/BRAF genotype were identified by univariate and multivariate analyses using the Cox proportional hazards model. The impact of KRAS/BRAF genotype on survival was analyzed using the Kaplan–Meier method.ResultsThe 5‐year survival rate of the cohort was 55.8%. The KRAS and BRAF mutation rates were 38.0 and 2.1%, respectively. BRAF genotype, but not KRAS, was found to be an independent prognostic biomarker (HR = 5.181, P = 0.002) after adjustment for other significant confounding clinicopathological variates: Number of liver metastases (HR = 1.983, P = 0.009), concomitant extrahepatic disease (HR = 1.858, P = 0.014), and surgical margin (HR = 3.241, P < 0.001). BRAF genotype was an independent prognostic biomarker in patients with liver metastases only after metastasectomy (HR = 6.245, P < 0.003).ConclusionsBRAF mutation is an independent prognostic biomarker for colorectal liver metastasectomy.

Published: February 2012

AbstractIn this paper we study the Cauchy‐Kowalewski extension of real analytic functions satisfying a system of differential equations connected to bicomplex analysis, and we use this extension to study the product in the space of bicomplex holomorphic functions. We also show how these ideas can be used to define a Fourier transform for bicomplex holomorphic functions.
Magnetic Fe3O4‐PS‐Polyacetylene Composite Microspheres Showing Chirality Derived From Helical Substituted Polyacetylene

Published: February 2012

AbstractThis communication reports the first integration of two significant concepts, “macromolecular helicity‐derived chirality,” and “magneticity” in one single microsphere entity. The novel chiral magnetic composite microspheres consisted of magnetic Fe3O4 nanoparticles and optically active helical substituted polyacetylene. Therefore, they exhibited both remarkable optical activity and magneticity. The microspheres adsorbed (R)‐(+)‐1‐phenylethylamine much more quickly than the other enantiomer, demonstrating the potential applications of the chiral magnetic composite microspheres in chiral recognition and chiral resolution.

Published: February 2012

AbstractAimTo evaluate the efficacy and proper use of in‐and‐out catheterization as a strategy for trial without catheterization (TWOC) for treatment of acute urinary retention (AUR).MethodsRetrospective analysis of 515 patients who visited the emergency room with AUR from January 2004 to December 2008 was conducted. Patients were segregated to one of two groups, depending on management of AUR (in‐and‐out catheterization at one time: Group 1 or indwelling catheter: Group 2). To characterize the optimal patient characteristics particularly fitting for Group 1 among each success subgroup, Fisher's linear discriminant analysis (LDA) was then conducted. Using an equation from LDA, the hit ratio was evaluated in a prospective trial from July to December 2009.ResultsTWOC success rate was 25.1% for Group 1 and 30.3% for Group 2. In successful cases, age, retention volume, and prostate sizes were significantly lower than those of failure counterparts in both Groups 1 and 2. Among these, age and retention volume were finally selected for LDA. When comparing successful cases, these two were significantly lower in Group 1 than Group 2. LDA showed an 81.6% hit ratio for cases with successful TWOC. In a prospective trial of 28 patients, using an equation from LDA, five of seven patients in Group 1 (71.4%) and 16 of 21 patients (76.2%) in Group 2 succeeded in their initial TWOC.ConclusionsThese results suggest the efficacy of in‐and‐out catheterization as a way of attempting TWOC, particularly for the patient with relatively low retention volume and younger age.

Resource allocation in an asymmetric technology race with temporary advantages
Authors: Golany Boaz , Kress Moshe , Penn Michal , Rothblum Uriel G. 
Published: February 2012

AbstractWe consider two opponents that compete in developing asymmetric technologies where each party's technology is aimed at damaging (or neutralizing) the other's technology. The situation we consider is different than the classical problem of commercial R&D races in two ways: First, while in commercial R&D races the competitors compete over the control of market share, in our case the competition is about the effectiveness of technologies with respect to certain capabilities. Second, in contrast with the “winner‐takes‐all” assumption that characterizes much of the literature on this field in the commercial world, we assume that the party that wins the race gains a temporary advantage that expires when the other party develops a superior technology. We formulate a variety of models that apply to a one‐sided situation, where one of the two parties has to determine how much to invest in developing a technology to counter another technology employed by the other party. The decision problems are expressed as (convex) nonlinear optimization problems. We present an application that provides some operational insights regarding optimal resource allocation. We also consider a two‐sided situation and develop a Nash equilibrium solution that sets investment values, so that both parties have no incentive to change their investments. © 2012 Wiley Periodicals, Inc.

The Effect of Requiring Private Employers to Extend Health Benefit Eligibility to Same‐Sex Partners of Employees: Evidence from California
Authors: Buchmueller Thomas C. , Carpenter Christopher S. 
Published: February 2012

AbstractHealth disparities related to sexual orientation are well documented and may be due to unequal access to a partner's employer‐sponsored insurance (ESI). We provide the literature's first evaluation of legislation enacted by California in 2005 that required private employers within the state to treat employees in committed same‐sex relationships in the same way as employees in different‐sex marriages with respect to ESI. Our analysis uses data on sexual orientation, partnership, and health insurance from the 2001 to 2007 California Health Interview Surveys (CHIS). Prior to the reform, partnered gay men and lesbians were significantly less likely to have ESI in someone else's name than partnered heterosexuals. Pooling data from 2001 to 2007, we find that the reform had no effects on differences in insurance outcomes between gay and straight men. We find some evidence that the reform increased partnership, reduced full‐time employment, and increased health insurance coverage among lesbians relative to heterosexual women. The increases in insurance coverage for lesbians are consistent with a role for expanded dependent ESI, suggesting that such policies may reduce sexual orientation‐based insurance disparities among women.

Published: February 2012

AbstractBackgroundCurrent guidelines recommend the use of combined hormonal contraceptive pills for menstrual suppression in pediatric blood and marrow transplant (BMT) recipients but recent research reveals that provider practice varies. This study was designed to describe the current practice for managing menstrual issues, that is, menstrual suppression and uterine bleeding, in pediatric BMT patients and to better understand health care providers' practices in the use of gonadotropin‐releasing hormone agonists (GnRHa).ProcedureA cross sectional survey consisting of 53 questions was distributed via email to principal investigators in the Pediatric Blood and Marrow Transplant Consortium (PBMTC). Responses were collected using www.surveymonkey.com.ResultsMenstrual suppression and uterine bleeding in pediatric BMT patients are primarily managed by pediatric oncologists (97%). The most frequently reported hormonal method used for induction of therapeutic amenorrhea was GnRHa (41%). The top three reasons for choosing a method were greater likelihood of amenorrhea, concerns about side effects, and possible gonadal protection. Continuous combined hormonal contraceptive pills were the most commonly used method for the management of clinically significant uterine bleeding regardless of primary method used for menstrual suppression.ConclusionDespite the 2002 PBMTC guidelines, wide variation in menstrual suppression management practices still exists. Our data show that use of GnRHa is more common than previously reported. Additional research is needed to develop evidence‐based practice guidelines in pediatric BMT patients.

New piezoelectric damping composites of poly(vinylidene fluoride) blended with clay and multi‐walled carbon nanotubes
Authors: Geng Chengzhen , Wang Jianchuan , Zhang Qin , Fu Qiang 
Published: February 2012

AbstractDamping materials are used to control mechanical vibrations, and piezoelectric damping composite is a very promising material due to its unique mechanism. In this study, a potential piezoelectric damping composite was developed by simply melt mixing poly(vinylidene fluoride) (PVDF) with small amounts of organic modified montmorillonite (OMMT) and multi‐walled carbon nanotubes (MWCNTs). The piezoelectric, mechanical and electrical properties were investigated using a dynamic mechanical analyser, direct current electrical resistivity measurements, X‐ray diffraction, Fourier transform infrared spectroscopy and the direct quasi‐static d33 piezoelectric coefficient method. It was found that the damping property of PVDF can be greatly improved by adding both MWCNTs and OMMT, and the composite containing 1.9 wt% of MWCNTs and 3 wt% of OMMT showed the best damping property. A model and an approximate calculation were applied to explain the improved damping property. Moreover, similar mechanical properties of PVDF composites were observed in the tensile testing and dynamic mechanical analyser measurements. Copyright © 2012 Society of Chemical Industry

Published: February 2012

AbstractA series of novel fatty acid‐based diols were designed and synthesized from sunflower and ricin oils using optimized chemical reactions and purifications. These diols were categorized in two different types: (i) fatty acid‐based monoester containing diols (FAmE‐1 to FAmE‐6) and (ii) fatty acid‐based diester containing diols (FAdE‐1 to FAdE‐8). Their synthesis involved a series of reactions such as transesterification, epoxidation, ring opening of epoxide, and thiol‐ene additions. Analyses of these new fatty acid‐based diols were performed by HPLC/GC and NMR spectroscopy. The latter were then demonstrated as polyurethane (PU) precursors in the bulk polymerization with isophorone diisocyanate in the presence of dibutyl tin dilaurate as a catalyst. The effects of the diol nature and purity on the PU synthesis and properties were investigated. The structural characterization of the different PUs was carried out by means of FTIR, 1H NMR, and 1H DOSY NMR spectroscopy. The thermomechanical and rheological properties of these new PUs were found dependent on the chemical structure and purity of the diol building block. © 2012 Wiley Periodicals, Inc.
