The compound undergoes a magnetic Co-Co sublattice ordering at similar to 150 K, and a second magnetic Dy-Dy sublattice ordering transition at 22 K. Magnetization and modified Arrott plots indicate that DyCo3B2 compound undergoes a second-order phase transition at

similar to 22 K. A large reversible magnetocaloric effect has been observed around Dy-Dy sublattice ordering temperature. The values of maximum magnetic entropy change (-Delta S-M(max)) reach 7.4 and 15.1 J kg(-1) K-1 for the field change of 2 and 7 T with no obvious hysteresis loss around 25 K; the corresponding values 5-Fluoracil mouse of maximum adiabatic temperature changes (Delta T-ad(max)) are evaluated to be 6.4 and 13.8 K, respectively. The large reversible Delta S-M(max) and Delta T-ad(ma), as well as considerable relative cooling power, make DyCo3B2 compound a suitable candidate for low temperature magnetic refrigeration.

“Controlled thermoresponsive PET track-etched membranes were synthesized by grafting N-isopropylacrylamide (NIPAAm) onto the membrane surface via atom transfer radical polymerization (ATRP). The initial measurements were made to determine the anchoring of ATRP initiator on PET membrane surface. Thereafter, polymerization was carried out to control the mass

of polymer by controlling reaction time grafted from the membrane surface and, ATR-FTIR, grafting degree measurements, water contact angle measurements, TGA, and SEM were used to characterize changes in the chemical functionality, surface and pore morphology of membranes as a result of modification. Water flux measurements were used to evaluate the thermoresponsive capacity of grafted membranes. The results show the grafted PET track-etched membranes exhibit rapid and reversible response of permeability to environmental

temperature, and its permeability could be controlled by controlling polymerization selleck inhibitor time using ATRP method. (C) 2011 Wiley Periodicals, Inc. J Appl Polym Sci 122: 2047-2053, 2011″
“Although the origins of the high effective permittivity observed in CaCu3Ti4O12 (CCTO) ceramics and single crystals at similar to 100-400 K have been resolved, the relaxorlike temperature- and frequency-dependence of permittivity obtained from fixed frequency capacitance measurements at higher temperatures reported in the literature remains unexplained, especially as CCTO adopts a centrosymmetric cubic crystal structure in the range of similar to 35-1273 K. Impedance spectroscopy studies reveal that this type of relaxorlike behavior is an artifact induced mainly by a nonohmic sample-electrode contact impedance. In addition, an instrument-related parasitic series inductance and resistance effect modifies the measured capacitance values as the sample resistance decreases with increasing temperature.

“Laparoscopic Roux-en-Y gastric bypass (RYGB) is one of the most common bariatric procedures performed. Dumping syndrome, intolerance to RYGB-induced restriction, and weight selleck kinase inhibitor loss issues are possible problems bariatric surgeons are confronted with. This study reports the feasibility, safety, and outcomes of laparoscopic reconversion of RYGB to original anatomy (OA) as treatment of these complications.

Between January 2005 and April 2008, eight patients benefited from laparoscopic GSI-IX reconversion of RYGB to OA. Reason was dumping syndrome without postprandial hypoglycemia (three), intolerance to RYGB-induced restriction (three), too much (one) and too little weight loss (one). Mean weight and body mass index (BMI) at RYGB were 104.7 +/- 19.3 kg and 38.7 +/- 6 kg/m(2), respectively. Four patients suffered of obesity co-morbidities. Mean time

between RYGB and reconversion was 21 +/- 18.8 months. Mean weight, BMI, and % excess weight loss at reconversion was 66.8 +/- 21.7 kg, 20.1 +/- 7 kg/m(2), and 23.7 +/- 55%, respectively. The procedure involved dismantling both gastrojejunostomy and jejunojejunostomy, reanastomosing gastric pouch to gastric remnant, and proximal alimentary limb end to distal biliary limb end.

Mean operative time was 132.2 +/- 29.5 min. There were no conversions to open surgery and no early complications. Gastrogastrostomy was this website performed manually (four) and by linear

stapler (four), and jejunojejunostomy by linear stapler (eight). Mean hospital stay was 7.7 +/- 3.5 days. After a mean follow-up of 18.3 +/- 9.2 months, two patients continued to further lose weight, two patients maintained the same weight, and four patients presented weight regain. Gastroesophageal reflux disease appeared in three patients.

Laparoscopic reconversion of RYGB to OA is feasible and safe. Dumping syndrome and intolerance to RYGB-induced restriction are resolved. The anatomy remains one of the aspects besides nutritional and psychological factors in cases of reconversion for weight issues.”
“Objective: Balance of prognostic factors between treatment groups is desirable because it improves the accuracy, precision, and credibility of the results. In cluster-controlled trials, imbalance can easily occur by chance when the number of cluster is small.

Severe postoperative pain was defined as NAS >= 5. Data were analyzed using chi square, Fisher’s exact test or analysis of variance, with alpha = 0.05.

PACU pain and the incidence of severe PACU pain increased with surgical complexity (P < 0.005). PACU pain scores averaged 4.71 +/- 0.24 and 57.7% of subjects experienced severe pain. Postoperative pain scores

at 1 or 6-12 months did not vary by surgical PKC412 supplier complexity and averaged 2.21 +/- 0.32 and 0.74 +/- 0.22, respectively. Severe postoperative pain was experienced by 22.1% of subjects at 1 month and 8.2% of subjects at 6-12 months. Older age and systolic hypertension were associated with less PACU pain. Non-White race, obesity, and high PACU opioid use compound screening assay were associated with greater postoperative pain at 1 month. Non-White people also had greater postoperative pain at 6-12 months.

The results suggest that nearly 60% of breast surgery patients experience severe acute postoperative pain, with severe pain persisting for 6-12 months in almost 10% of patients.”
“Introduction: Functional outcome and quality of life (QOL) domains are important outcomes after curative therapy for prostate

cancer. Although useful for scientific purposes, QOL questionnaires may be too extensive for daily routine, and single questions or interview-assessed outcomes may be more practical alternatives. The QOL outcomes of these measures were compared. Materials and Methods: The QOL of patients undergoing Robot-Assisted Radical Prostatectomy Selleckchem AG-881 (RARP) in our hospital was monitored before and after treatment using both brief standardized interview questions, as well as more extensive validated questionnaires. The interview questions address erectile function and urinary continence with only one question on each subject (both four response items).

Questionnaires included a total of 74 questions (EORTC-QLQ-C30, EORTC-QLQ-PR25, international index of erectile function-15, and international consulation on incontinence questionnaire-short form). Results: In 925 RARP patients, pre- and postoperative interview and questionnaire QOL data were available with a median follow up of 20 months. Improvement in both erectile function and continence scores occurred up till 2 years after the RARP for both interview- and questionnaire-based evaluations. On an individual patient basis, interview scores poorly correlated with questionnaire-based domains for continence and erectile function. Single questions from the questionnaire showed better correlation with domain scores. Functional recovery of continence after 1 year was worse when assessed by questionnaire than by interview evaluation. A decrease in physical (8%) and overall QOL (12%) after prostatectomy as assessed by the EORTC-QLQ-C30 questionnaire was better predicted by questionnaire-based than interview-based scores.

Retrospective review of all gastric cancer surgeries from 2005 to

Retrospective review of all gastric cancer surgeries from 2005 to 2009 ( = 2,588) revealed 53 patients (2.0%) who developed anastomotic leakage and were treated conservatively. EN was performed via a nasointestinal tube inserted using a guidewire under X-ray

fluoroscopy. Clinical outcomes and complications following EN were compared with those in patients treated with PN (historical control group). The severity of complications was evaluated according to the Clavien-Dindo classification.

Fifty patients were included in the final this website analysis (three patients died): 29 patients managed by EN and 21 managed by PN. There were no significant differences in clinical outcomes and the frequency of total complications between the two groups; however, there were fewer tube/catheter-related complications in the EN compared with the PN group (1 vs. 7, respectively; < 0.01). There was one epistaxis (3.4%; grade I) in the EN group and seven catheter infections (33.3%; grade II) in the PN group. The risk of grade II or higher complications was greater in the PN than the EN group (11 vs. 4, respectively; < 0.01), with the greatest difference seen in the incidence of catheter infections. On days 7, 10, and 15 after diagnosis of leakage, the white Mdivi1 blood cell count and C-reactive protein levels were higher in the PN than in the EN group. The PN group required prolonged intravenous antibiotic infusion ( < 0.01).


tube insertion with EN can be performed safely for patients with anastomotic leakage. A major advantage of EN is fewer infectious complications. Because EN was not inferior to PN in terms of clinical outcome, we recommended that it is used in patients with anastomotic leakage after gastric cancer surgery.”
“OBJECTIVES: Laser lead extraction is a challenging procedure, especially in patients with old or multiple pacemaker (PM) or implantable cardioverter defibrillator (ICD) leads. The mechanical force is a leading cause of

complications during the extraction procedure. Use of new laser sheaths, which deliver a rate of 80 pulses per second, may probably reduce intraoperative adverse events by reduction of extraction force.

METHODS: selleck chemicals llc Between January 2012 and April 2013, 76 PM and ICD leads were treated in 38 patients using GlideLight 80 Hz laser sheaths. Indications for lead removals were pocket infection (42.1%), septicaemia or endocarditis (23.7%), lead dysfunction (31.6%) and upgrade from PM to ICD (2.6%). Data on procedural success rates, intra-and postoperative outcomes, as well as 30-day mortality were collected into a database and analysed retrospectively.

RESULTS: The mean patient age was 62.0 +/- 17.7 years (range 18-83), and 73.7% were male. The mean time from initial lead implantation was 96.0 +/- 58.3 months (range 24-288). Thirty-seven (48.7%) PM and 39 (51.3%) ICD leads had to be extracted. The mean procedural time was 68.3 +/- 27.3 min (range 35-115).

95 (1.59-5.48). The latter tendency remained strong until 1965. Among non-allergics, the increase in surgery probability by age cohort showed the same tendency, but the relationship was less strong than for those with allergy.

Conclusions: Despite a twofold increase in recurrent OM and OM surgery from 1925 to 1945, the proportion of OM and OM surgery have been stable since 1945. Our findings suggest a shift in clinical practice, most likely

indicating a change in surgery from acute infections to otitis media with effusion (OME). (C) 2010 Elsevier FG-4592 mw Ireland Ltd. All rights reserved.”
“Background: Our study was designed to (1) investigate the risk factors associated with cervical or trochanteric hip fractures; and (2) identify the risk factors for increased mortality in the elderly population sustaining hip fractures, after adjusting the miscellaneous

baseline prefracture conditions.

Methods: Two hundred seventeen elder patients with first-time, low-trauma hip fractures were enrolled. The follow-up time ranged from 35 months to 56 months. Potential risk factors for hip fracture types included (1) the 77 items on the self-reported questionnaire; (2) the body height, weight, and body mass index; (3) tests Ferrostatin-1 datasheet of coordination, handgrip strength, and peak expiratory flow rate; and (4) the bone mineral density variables. GTFN ratio was defined as the bone mineral density ratio between the greater trochanter and the femoral neck. Multivariate logistic regression and Cox regression models were used for analysis. The population attributable risk proportion of death to each significant factor was estimated.

Results: Risk factors for trochanteric fractures include a GTFN ratio <= 0.81, being male, and an age >80 years. Risk factors for higher mortality after hip fracture included trochanteric fracture, body mass index <= 20 (kg/m(2)), poor self-assessed health status, peak expiratory flow rate <=

215 (L/min), being male, illiteracy, and coordination abnormality, in the declining order of population attributable risk proportion. Trochanteric fractures had a significantly higher cumulative mortality at 36 months, 48 months, and 60 months than cervical fractures.

Conclusions: The novel GTFN ratio was associated with hip fracture sites. Clinically, cervical and trochanteric fractures Alpelisib clinical trial represent different disease entities because of the difference in their mortality rates.”

Data from the

cohort were used to examine the ability of the CRIS-CAT to predict key one year outcomes. Data from the CRIS-CAT administration study were used to calculate ICC (2,1) minimum detectable change (MDC), and average number of items used during CAT administration.

Results: Reliability scores for all scales were above 0.75, but decreased at both Selleckchem Talazoparib ends of the score continuum. CRIS-CAT scores were correlated with concurrent validity indicators and differed significantly between the three Veteran groups (P < .001). The odds of having any Emergency Room visits were reduced for Veterans with better CRIS-CAT scores (Extent, Perceived Satisfaction respectively: OR = 0.94, 0.93, 0.95; P < .05). CRIS-CAT scores were predictive of SF-12 physical and mental health related quality of life scores at the 1 year follow-up. Scales had ICCs >0.9. MDCs were 5.9, 6.2, and 3.6, respectively for Extent, Perceived and Satisfaction subscales. Number of items (mn, SD) administered at Visit 1 were 14.6 (3.8) 10.9 (2.7) and 10.4 (1.7) respectively for Extent, Perceived and Satisfaction subscales.

Conclusion: The CRIS-CAT demonstrated sound measurement properties including INCB024360 solubility dmso reliability, construct, known group and predictive validity, and it was administered with minimal respondent burden. These findings support the use

of this measure in assessing community reintegration.”
“Sleep and its disorders are increasingly becoming important in our sleep deprived society. Sleep is intricately connected to various hormonal and metabolic processes in the body and is important in maintaining metabolic homeostasis. Research shows that sleep deprivation and sleep disorders may have profound metabolic and cardiovascular implications. Sleep deprivation, sleep disordered breathing, and circadian misalignment are believed to cause metabolic dysregulation through myriad pathways involving sympathetic overstimulation, hormonal imbalance, and VX-809 subclinical inflammation. This paper reviews sleep and metabolism, and how sleep deprivation and sleep disorders

may be altering human metabolism.”
“Background: Population based studies are important for prevalence, incidence and association studies, but their external validity might be threatened by decreasing participation rates. The 50 807 participants in the third survey of the HUNT Study (HUNT3, 2006-08), represented 54% of the invited, necessitating a nonparticipation study.

Methods: Questionnaire data from HUNT3 were compared with data collected from several sources: a short questionnaire to nonparticipants, anonymous data on specific diagnoses and prescribed medication extracted from randomly selected general practices, registry data from Statistics Norway on socioeconomic factors and mortality, and from the Norwegian Prescription Database on drug consumption.

8 [3.5-4.3]). Standardised mortality ratio (SMR) was higher for type 1 compared with type 2 diabetic patients (4.5 [3.8-5.3] vs 3.5 [3.1-4.0], p = 0.032). For cardiovascular and non-cardiovascular deaths SMRs were 5.6 (95% CI 4.8-6.6) and 2.7 (2.3-3.1) and did not differ according to type of diabetes. SMRs for all-cause and cardiovascular mortality were significantly higher in women compared with men in type 1 (p <0.05 and p <0.01) and type 2 diabetes (p <0.001 and p <0.01). In both types of diabetes, SMRs

significantly decreased during the last two decades R406 inhibitor (p for trend 0.004 and 0.002).

Conclusions: Patients with type 1 and type 2 diabetes had an increased long-term mortality compared with the general Swiss population. Excess mortality was higher in type 1 compared with type 2 diabetes and in women compared with men for both types of diabetes, but steadily

decreased over the last two decades.”
“Study Design. Prospective longitudinal cohort.

Objective. To evaluate the efficacy of hydroxyapatite (HA) grafts in combination with cervical plates in terms of fusion, restoration, and maintenance of cervical lordosis and to compare clinical and radiologic outcomes of patients who experienced graft breakage with patients who did not.

Summary of Background Data. The most common complication related to the use of HA graft for cervical anterior fusion is graft breakage. However, the implication of graft breakage in terms of loss of graft height, cervical alignment, plate migration, and clinical outcomes has not been adequately evaluated.

Methodology. A prospective study of 40 patients who underwent anterior cervical PU-H71 in vivo fusion in which HA graft and plate systems were used. Clinical and radiologic assessments were made 1 month after surgery and again at the final follow-up.


At the final follow-up evaluation, 80% of patients had an excellent clinical outcome, 15% had a good outcome, and 5% had a fair outcome based on Odom’s classification. All patients achieved lordotic alignment in the immediate EPZ015666 in vitro postoperative period. Graft breakage was observed in 25% of cases. Patients who experienced HA block breakage have 21 times more chance to have intervertebral height loss greater than 2 mm, 4.9 times more likely to undergo loss of cervical alignment exceeding 3, and 12.4 times more likely to present migration of the plates when compared to patients who had normal HA grafts.

Conclusion. Despite the positive clinical results observed in this study, breakage of HA grafts was a common complication occurring in 25% of patients. Graft breakage was associated with strut height loss of more than 2 mm, loss of cervical alignment exceeding 3 and a higher rate of plate migration. These changes related to the HA graft breakage demonstrate the necessity to continue searching for better grafting methods to perform cervical interbody fusion.

Arterial stiffness was assessed by a TensioClinic arteriograph, a recently validated technique. Brachial arterial FMD and ccIMT were determined

using high-resolution ultrasonography. Autoimmune patients exerted impaired FMD (3.7 +/- 3.8%), increased ccIMT (0.7 +/- 0.2 mm), AIx (1.2 +/- 32.2%), and PWV (9.7 +/- 2.4 m/s) in comparison to control subjects (FMD = 8.4 +/- 4.0%; ccIMT = 0.6 +/- 0.1 mm; Aix = -41.1 +/- 22.5%; PWV = 8.0 +/- 1.5 m/s; p < 0.05). We found a significant negative correlation of FMD with AIx (R = -0.64; p < 0.0001) and PWV (R = -0.37; p = 0.00014). There were significant positive correlations between mTOR inhibitor ccIMT and AIx (R = 0.34; p = 0.0009), ccIMT and PWV (R = 0.44; p < 0.0001), as well as AIx and PWV (R = 0.47; p < 0.0001).

AIx, PWV, and ccIMT positively correlated and FMD negatively correlated with the age of the autoimmune patients. Arterial stiffness indicated by increased AIx and PWV may be strongly associated with endothelial dysfunction and overt atherosclerosis in patients with autoimmune diseases. Assessment of arterial stiffness, FMD, and ccIMT are reproducible and reliable noninvasive techniques for the complex assessment of vascular abnormalities in patients at high risk.”
“The PD-1/PD-L1 signaling pathway effects of Ni dopants and O vacancies on the electronic structure and magnetic properties of Ni-doped SnO2 are studied using the first-principles density functional calculation. Both of generalized

gradient approximation (GGA (and GGA+U calculations show that substitutional Ni atoms at Sn sites cannot induce magnetic moment in Ni-doped SnO2 without O vacancy. O vacancies prefer to locate near Ni atoms and induce the magnetic moments at Ni atom and its nearest O atoms. Moreover, O vacancies in a chain connecting two Ni atoms of large distance can lead to a long-range ferromagnetic (FM (coupling between the two Ni atoms. The strength of coupling calculated by GGA+U is about triple that calculated by GGA. The spin density distribution shows that the long-range BX-795 FM coupling between two Ni atoms can be explained in terms of the bound magnetic polaron model. (C) 2010 American Institute of Physics.

“Introduction: The phase III TITAN trial evaluated the use

“Introduction: The phase III TITAN trial evaluated the use of darunavir with low-dose ritonavir (DRV/r)

600/100 mg twice daily (bid) compared with lopinavir with low-dose ritonavir (LPV/r) in treatment-experienced, lopinavir-naive patients. This study estimates the cost effectiveness of DRV/r from a US societal perspective when compared with LPV/r in treatment-experienced patients with a profile similar to those TITAN patients who had one or more International AIDS Society – USA (IAS-USA) primary protease inhibitor (PI) resistance-associated mutations (RAMs) at baseline. This NMS-E628 population had less advanced HIV disease and a broader range of previous PI exposure/failure (0-2 PIs) at enrolment than those in the darunavir phase IIb POWER trials.

Methods: An existing Markov model containing

six health states defined by CD4 cell count range (>500, 351-500, 201-350, 101-200, 51-100 and 0-50 cells/mm(3)) and an absorbing state of death was adapted. Baseline demographics, CD4 cell count distribution and antiretroviral drug usage, virological response (at week 24), and immunological response estimates and matching transition probabilities were based on data collected directly from the one or more IAS-USA PI mutation subpopulation during the first 48 weeks of the TITAN trial, as well as from published literature. Patients were assumed to switch to a regimen containing tipranavir plus an optimized background regimen after treatment failure. For each CD4 cell count range

or health state, the utility values, HIV and non-HIV-related mortality rates, and non-antiretroviral-related VE 822 cost of HIV care estimates were derived from published literature. Unit costs were derived from official local sources. A lifetime horizon was taken in the base-case analysis.

Results: The base-case analysis predicted discounted quality-adjusted survival gains of 0.493 quality-adjusted life-years (QALYs) for DRV/r compared with LPV/r, resulting in an incremental cost-effectiveness ratio (ICER) of US$23 057 per QALY gained over a lifetime horizon. Probabilistic sensitivity analysis indicated a 0.754 probability of an ICER below the threshold of US$50 000 per QALY gained. DRV/r remained cost effective over all parameter ranges tested in extensive one-way sensitivity analyses and variability analyses, which examined the impact of input parameter uncertainty and changes in model assumptions and treatment patterns, respectively. Shortening the model time horizon had the largest impact on the ICER, reducing it most notably to US$4919 with a 10-year time horizon.

Methods: We retrospectively compared results of completely portal robot lobectomy with 4 arms (CPRL-4) against propensity-matched controls and results after technical changes to CPRL-4.

Results: In 14 months, 168 patients underwent robotic pulmonary resection: 7 had metastatic pleural disease, 13 had conversion to open procedures, and 148 had completion robotically (106 lobectomies, 26 wedge resections, 16 segmentectomies). All

patients underwent R0 resection and removal of all visible lymph nodes (median of 5 N2, 3 N1 nodal stations, 17 lymph nodes). The 106 patients who underwent CPRL-4 were compared with 318 propensity-matched patients selleck chemicals who underwent lobectomy by rib- and nerve-sparing thoracotomy. The robotic group had reduced morbidity (27% vs 38%; P = .05), lower mortality (0% vs 3.1%; P = .11), improved PCI-32765 ic50 mental quality of life (53 vs 40; P < .001), and shorter hospital stay (2.0 vs 4.0 days; P = .02). Results of CPRL-4 after technical modifications led to reductions in median operative time (3.7 vs 1.9 hours; P < .001) and conversion (12/62 vs 1/106; P < .001). Technical improvements were

Conclusions: The newly refined CPRL-4 is safe and yields an R0 resection with complete lymph node removal. It has lower morbidity, mortality, shorter hospital stay, and better quality of life than rib- and nerve-sparing thoracotomy. Technical advances are possible to shorten and improve the operation.

“The localization of stilbene synthase (STS) (EC in grape berry (Vitis vinifera L.) was investigated during fruit development. The berries were collected at 2, 4, 7, 11, and 15 weeks postflowering from the cultivar Nebbiolo during the 2005 and 2006 growing seasons. High-performance liquid chromatography analysis showed that berries accumulated cis- and

trans-isomers of resveratrol mainly in the exocarp throughout fruit development. Immunodetection Rigosertib clinical trial of STS protein was performed on berry extracts and sections with an antibody specifically developed against recombinant grape STS1. In agreement with resveratrol presence, STS was found in berry exocarp tissues during all stages of fruit development. The labeled epidermal cells were few and were randomly distributed, whereas nearly all the outer hypodermis cells were STS-positive. The STS signal decreased gradually from exocarp to mesocarp, where the protein was detected only occasionally. At the subcellular level, STS was found predominantly within vesicles (of varying size), along the plasma membrane and in the cell wall, suggesting protein secretion in the apoplast compartment.
