“The NdMnO3/Mn3O4 nanocomposite film was synthesized by spontaneous phase decomposition of NdMn2O5. NdMnO3 is a canted A-type antiferromagnet with a Neel temperature of about 75 K, while Mn3O4 is ferrimagnetic below its Curie temperature of 42 K. Ferromagnetic order of

the Nd moments in NdMnO3 around 15 K has been confirmed. These moments are antiferromagnetically coupled with the Mn moments. The effect of the consecutive magnetic orderings of NdMnO3 on the exchange coupling between NdMnO3 and Mn3O4 has been investigated. The temperature dependence of the exchange bias manifests itself as a peak at 20 K, which is explained in terms of competing ferromagnetic and antiferromagnetic coupling of the Mn and Nd magnetic sublattices with Mn moments of Mn3O4, respectively.

“To investigate the morphology, crystallization properties of reversible phase and thermal sensitive shape memory properties of CW/SMPU (Cellulose Whisker/Shape Memory Polyurethane) nano-composite, the CW/SMPU nano-composite having CW contents of 0.1-3.8 wt % were prepared. SEM investigation showed the evolution of reversible phase morphology from spherolite crystallization structure to uniform matrix with tiny CW aggregates with the addition

of CW into the SMPU matrix. DSC and isothermal Selleckchem SCH727965 crystallization kinetic method revealed the effect of CW on crystallization properties of reversible phase and fixed phase, suggesting that the effect of CW on the crystallization of hard segment phase is not comparable with thermal history; the more CW causes the higher crystallization rate of reversible phase; the crystallization mechanism of reversible phase in nano-composite gradually evolves to heterogeneous nucleation and crystal growth in two dimensions with the increase of CW content; the excellent nucleation effect of CW for the reversible phase leads to the drop of activity energy from 134.1 kJ/mol (N-0), to 95.1 kJ/mol (N-4). Cyclic tensile tests illustrate the addition of CW content can engender rapid shape fixity ability after a relative short cooling time; the shape fixity ratio of nano-composite and the control sample after sufficient cooling all can be identically high.

“Background Few published studies have analyzed serum lidocaine levels and individual patient characteristics

affecting metabolism after application of compounded topical anesthetics. Objective To measure serum lidocaine levels during and cutaneous side effects after standardized application of 23% lidocaine/7% tetracaine compounded anesthetic to the face of healthy volunteers. Methods and Materials Fifty-two volunteers were enrolled, and compounded 23% lidocaine/7% tetracaine ointment was applied to their faces for 2hours. Lidocaine levels were determined every 30minutes during application and for 2hours after removal. APR-246 Follow-up telephone calls 3days later assessed cutaneous side effects. Results Median peak lidocaine level was 1.15 mu g/mL, and the highest peak lidocaine level in an individual was 3.4 PND-1186 mw mu g/mL. Higher serum lidocaine levels were found in men (p<.01), nonwhite volunteers (p=.02), and those with larger facial surface area (p=.04). Age and body mass index did not affect lidocaine levels. Irritant contact dermatitis was common, resulting in hyperpigmentation in some patients. Conclusion Facial surface area, male

sex, and nonwhite ethnicity were associated with higher serum lidocaine levels after topical application of lidocaine. Compounded anesthetics containing lidocaine should be used with caution under the direct supervision of a physician.”
“Background:

Orthotopic liver transplantation (OLT) is performed as a definitive treatment of acute and chronic liver failure. The prevalence of acute and chronic kidney diseases is substantially higher in this population secondary to diverse etiologies. Combined kidney-liver transplantation (CKLT) is widely performed in some centers,

even though there are no definitive studies which support or contradict this practice.

Methods:

We comprehensively reviewed OLT as well as CKLT data from US transplant centers provided by United Network of Organ Sharing (UNOS).

Results:

The incidence of CKLT as a percentage of total OLTs performed has been increasing, especially in the post-MELD era (2002 Blebbistatin in vivo and after). Moreover, there is a great disparity among centers in regard to percentage of CKLTs to total OLTs.

Conclusion:

We conclude that there is much difference of opinion among US transplant centers as to indications for CKLT. A more scientific approach to this problem including studies to assess the role of kidney biopsy in determining renal outcome after OLT is needed.”

“The surface of a polypropylene (PP) film was activated

with chemical, electrochemical, and physical methods, and the effectiveness of these methods was compared. The effects of PP activation were assessed with attenuated total reflection IR spectroscopy (ATR-IR), SEM microscopy, and an analysis, based on the liquid contact angle, of the free energy components of the surface. The activation of the PP surface, which was dependent on the oxidizing medium, increased the energy of the PP surface layer and formed new chemical (carbonyl) groups, which were identified by IR (ATR) absorption spectroscopy and confirmed by selective surface dyeing.

“This study investigates bipolar and nonpolar resistive-switching of HfO2 with various metal electrodes. Supported by convincing physical and electrical evidence, it is our contention that the composition of conducting filaments in HfO2 strongly depends upon the metal electrodes.

Nonpolar resistive-switching with the Ni electrode is attributed to the migration of metal cations and the corresponding electrochemical metallization. Conversely, oxygen-deficient filaments induced by anion migration are responsible for bipolar resistive-switching. It was also found that the characteristic nature of the

conducting filaments influences many aspects of switching characteristics, including the switching power, cycling variations, and retention at elevated temperatures. (C) 2011 American Institute of Physics. [doi:10.1063/1.3567915]“

“Background: Despite some problems related to accuracy and applicability of malaria rapid diagnostic tests (RDTs), they are currently the best option in areas with limited laboratory services for improving case management through parasitological diagnosis and reducing over-treatment. This

study was conducted in areas with declining malaria burden to assess; 1) the accuracy of RDTs when used at different community settings, 2) the impact of using RDTs on anti-malarial dispensing by community-owned resource persons (CORPs) and 3) adherence of CORPs to treatment guidelines by providing treatment based on RDT results.

Methods: Data were obtained from: 1) a longitudinal study of passive case detection of fevers using CORPs in six villages in Korogwe; and 2) cross-sectional surveys (CSS) in BIBF 1120 clinical trial six villages of Korogwe and Muheza districts, northeastern, Tanzania. Performance of RDTs was compared GSK461364 purchase with microscopy as a gold standard, and factors affecting their accuracy were explored using a multivariate logistic regression model.

Results: Overall sensitivity and specificity of RDTs in the longitudinal study (of 23,793 febrile cases; 18,154 with microscopy and RDTs results) were 88.6% and 88.2%, respectively. In the CSS, the sensitivity

was significantly lower (63.4%; chi(2) = 367.7, p < 0.001), while the specificity was significantly higher (94.3%; chi(2) = 143.1, p < 0.001) when compared to the longitudinal study. As determinants of sensitivity of RDTs in both BMS-754807 studies, parasite density of < 200 asexual parasites/mu l was significantly associated with high risk of false negative RDTs (OR >= 16.60, p < 0.001), while the risk of false negative test was significantly lower among cases with fever (axillary

temperature >= 37.5 degrees C) (OR <= 0.63, p <= 0.027). The risk of false positive RDT (as a determinant of specificity) was significantly higher in cases with fever compared to afebrile cases (OR >= 2.40, p < 0.001). Using RDTs reduced anti-malarials dispensing from 98.9% to 32.1% in cases aged >= 5 years.

Conclusion: Although RDTs had low sensitivity and specificity, which varied widely depending on fever and parasite density, using RDTs reduced over-treatment with anti-malarials significantly. Thus, with declining malaria prevalence, RDTs will potentially identify majority of febrile cases with parasites and lead to improved management of malaria and non-malaria fevers.”

The structure of the ThFe11C2 compound has three inequivalent iron sites with different local

environment. A strongly enhanced magnetic moment is observed on certain Fe positions, coexisting with much lower magnetic moments on other iron positions of the lattice. Band structure calculations indeed show that the Fe magnetic moments depend strongly on the local environment. The average Fe magnetic moment obtained from these calculations is in good agreement with the experimental average Fe moment obtained from magnetization measurements. The orbital contribution to the magnetic moment is found to be especially large on https://www.selleckchem.com/products/ABT-888.html the Fe 4b position. Comparing calculated hyperfine fields with experimental results, it is found that the calculated and experimental hyperfine fields are correlated. However, similarly to the results reported before for elemental Fe, the magnitude of all calculated Fe selleck compound hyperfine fields is about 25% smaller. The agreement with the Mossbauer measurements is improved by scaling the core polarization contribution and by estimating the orbital valence d-electrons contribution to the magnetic hyperfine fields using the local spin density approximation+dynamical mean field theory calculated

orbital moments. VC 2011 American Institute of Physics. [doi:10.1063/1.3567923]“
“A graft copolymer was synthesized by graft copolymerization of starch with styrene (St) and butyl acrylate (BA), using ferrous sulfate-hydrogen peroxide redox initiation system. The starch was pregelled in the presence of acrylonitrile (AN) in aqueous alkali at high temperature before graft polymerization. Major factors affecting the polymerization reaction were investigated. It was found that a graft copolymer with higher percentage conversion (PC), graft efficiency (GE) and

graft percentage (GP) was obtained by controlling the initiator concentration, concentration, and ratio of monomers and polymerization temperature. The optimum conditions were as follows: H(2)O(2) concentration, 12%; monomer concentration, 120%; St/BA ratio, 1 : 1; polymerization temperature, 65 degrees C. Fourier transform infrared spectroscopy and NMR analyses were used to gain information IPI-549 concentration on the structure of the products. It was demonstrated that St, BA, and AN had been successfully grafted onto starch and -CN had been saponified into -CONH(2) and -COO(-) to a certain degree when pregelling. Scanning electron microscope micrographs showed the coarse structure and broad network. The graft polymerization took place on the surface of starch granule and led to amorphization of the starch structure. Graft polymer had better thermal stability and was endowed with pseudo-plasticity. It was observed that the starch graft copolymer offers good properties such as water resistance as surface-sizing agent. (C) 2011 Wiley Periodicals, Inc.

Total fatty acid content was greatest (P < 0.001) for CONC and least (P < 0.001) for PA. Supplementation of grazing cattle increased (P < 0.001) total fatty acid content compared with PA, but concentrations were less (P < 0.001) than for CONC. Myristic and palmitic acid contents were greater ( P < 0.001) for CONC than for PO and PC, which were greater (P < 0.001) than for PA. HKI-272 Stearic acid content was greater (P < 0.01) for PO than for CONC,

de VX-689 price novo fatty acids in subcutaneous adipose tissue. Upregulation of SCD with grain feeding and reduced tissue CLA concentrations suggest that the decreased CLA concentrations were the result of limited substrate (trans-11 vaccenic acid) availability.”
“The surface modification of sulfur-prevulcanized natural rubber (SPNR) sheets by the polyethyleneimine-functionalized-poly(methyl methacrylate) (PMMA/PEI) nanoparticles was successfully performed via a simple dipping method. The percentage of surface coverage (Cs) of the nanoparticles on SPNR sheets was found to be affected by a variation of nanoparticle latex concentrations and immersion times. The adsorption isotherm of PMMA/PEI nanoparticles on SPNR sheets was analyzed and found to fit well to the Freundlich model. After coating, it can be observed that the presence of PMMA/PEI nanoparticles on SPNR surface had no effects over the SPNR mechanical properties e.g., tensile strength, elongation at break, and hardness. On the other hand, the coated SPNR sheets showed a reduction of surface friction coefficients and interfacial adhesion up to 45 and 59%, respectively.

46% referral rate of hyperbilirubinemi babies was much lower. The combined DPOAE/AABR screening technique revealed a referral rate of 5.03%, a false-positive rate of 2% and a false-negative rate of 0.06%. The false-positive rate was well below the suggested 3% of the American Academy of Pediatric. Comparisons of the referral rate, false-positive rate and false-negative rate of two hearing screening protocols (DPOAE alone and combined DPOAE/AABR) revealed significant differences (t-test, p < 0.05, p < 0.01, p < 0.01). 91 infants (3.03% of the NICU babies) who failed the combined DPOAE/AABR

screening were confirmed on hearing impairment. Of 22 babies who passed DPOAE screening but failed the AABR screening had a severe to profound hearing loss based on classic ABR.

“Objectives: Lingual thyroglossal duct cysts (TGDC) are rare and liable to be missed in a cursory clinical examination. This study aimed to report the details of lingual TGDC from the authors’ series and

review existing literature on the entity.

Methods: A 12 year retrospective survey of all cases of thyroglossal duct selleck chemicals anomalies managed at a tertiary teaching hospital was conducted to identify those with lingual TGDC. Their clinical presentation, investigations, diagnosis and management were analysed. Case series from anecdotal published English literature were critically reviewed with particular regard to diagnosis and management.

Results: Of 78 cases of thyroglossal duct anomalies, 3 were lingual TGDC. All were females. One neonate presented with feeding difficulty and was clinically misdiagnosed as a ranula.

The two older children presented with a cyst at the foramen caecum. The varied imaging and diagnostic dilemma are presented. The older children PR-171 clinical trial had cysts abutting the hyoid and were managed with transoral excision and a Sistrunk procedure; the neonate was managed with transoral excision only. This report also reviews the YM155 price sparse literature and discusses specific issues in their treatment. The differential diagnoses encompass a wide array of developmental and neoplastic entities. Specific anatomic imaging with USG/CT/MRI and functional evaluation with radionuclide thyroid scan are essential investigative modalities. Besides a classical Sistrunk procedure and simple transoral excision, newer less invasive treatment options including marsupialisation and alcohol ablation have

been reported.

Conclusions: In conclusion, the diagnosis and management of lingual TGDC needs to be individualised depending on their presentation and anatomic location. The Sistrunk’s procedure is ideal for those in close proximity to the hyoid; however complete cyst excision would suffice in the rest. (C) 2011 Elsevier Ireland Ltd. All rights reserved.”

“BACKGROUND

AND OBJECTIVE

Various types of allogenic skin substitutes composed of cryopreserved keratinocytes, fibroblasts, or both have been used for treatments of diabetic foot ulcers, but the effects have generally not been dramatic because cryopreservation impairs cell activities. The purpose of the study was to evaluate the use of non-cryopreserved fresh human fibroblast allografts in treating diabetic foot ulcers.

MATERIALS AND METHODS

Human dermal fibroblasts from healthy teenagers were cultured and applied over the foot ulcers of 37 patients with diabetes. Control treatment was performed in 18 patients. Eight weeks after treatment, the percentages of complete healing, mean healing times, and patient satisfaction were compared, with follow-up ranging from 6 to 40 months.

RESULTS

Our study showed that 83.8% of the treated group and 50.0% of the control group experienced complete healing. The times required for complete healing were 30.9 +/- 10.
