A nonlinear numerical model was developed to analyze reinforced concrete columns under combined axial load and bending up to failure. Results of reinforced concrete columns under eccentric compression tested to failure are presented and compared to results from a numerical nonlinear model. The tests involved 10 columns with cross-section of 250 mm × 120 mm, geometrical reinforcement ratio of 1.57% and concrete with compression strength around 40 MPa, with 3,000 mm in length. The main variable was the load eccentricity in the direction of the smaller dimension of cross-section. Experimental results of ultimate load and of the evolution of transverse displacements and concrete strains are compared with the numerical results. The estimated results obtained by the numerical model are close to the experimental ones, being suitable for use in verification of elements under combined axial load and bending.

National Grid is the electricity system operator in Great Britain and has an unique feature in so far as it is one of the world’s few for-profit system operators. In addition, the commercially orientation of the British market rules means that nearly every action taken by National Grid to operate the system has a cost associated to it. Based on those factors and in order to encourage National Grid to seek continuous improvements and drive for efficient and economic system operation, the regulator (Ofgem) offers an incentive scheme, whereby a target is agreed annually and any savings in relation to this target are shared between consumers and National Grid in the form of a profit. It is in National Grid’s best interest to have mechanisms to mitigate the impacts of volatility in the costs it faces as system operator so that it can implement cost saving actions without the risk of windfall losses (or gains) arising from sudden changes in uncontrollable drivers. The purpose of this paper is to share the experiences of National Grid in the operation of Great Britain's electricity system, with a special interest on the mechanisms created to manage the associated costs in response to the incentive scheme. It does so by describing the market operation in Great Britain and the costs drivers impacting National Grid’s system operation and illustrating the steps recently taken by National Grid to propose volatility mitigation mechanisms. It concludes with the rationale and expected results from the latest proposals as consulted with the industry for introduction in the incentive scheme starting on 1st April 2011. It is worth noting that with this work, the authors wish to both share the experience with other system operators and regulators in the world, as well as give British market participants an insight on the inner workings of National Grid.

AIM： To evaluate the safety and feasibility of bone marrow cell （BMC） transplantation in patients with chronic liver disease on the waiting list for liver transplantation. METHODS： Ten patients （eight males） with chronic liver disease were enrolled to receive infusion of autologous bone marrow-derived cells. Seven patients were classified as Child-Pugh B and three as Child-Pugh C. Baseline assessment included complete clinical and laboratory evaluation and abdominal MRI. Approximately 50 mL of bone marrow aspirate was prepared by centrifugation in a ficoll-hypaque gradient. At least of 100 millions of mononuclear-enriched BMCs were infused into the hepatic artery using the routine technique for arterial chemoembolization for liver tumors. Patients were followed up for adverse events up to 4 mo. RESULTS： The median age of the patients was 52 years （range 24-70 years）. All patients were discharged 48 h after BMC infusion. Two patients complained ofmild pain at the bone marrow needle puncture site. No other complications or specific side effects related to the procedure were observed. Bilirubin levels were lower at 1 （2.19 ± 0.9） and 4 mo （2.10 ± 1.0） after cell transplantation that baseline levels （238 ± 1.2）. Albumin levels 4 mo after BMC infusion （3.73 ± 0.5） were higher than baseline levels （3.47 ± 0.5）. International normalized ratio （INR） decreased from 1.48 （SD = 0.23） to 1.43 （SD = 0.23） one month after cell transplantation. CONCLUSION： BMC infusion into hepatic artery of patients with advanced chronic liver disease is safe and feasible. In addition, a decrease in mean serum bilirubin and INR levels and an increase in albumin levels are observed. Our data warrant further studies in order to evaluate the effect of BMC transplantation in patients with advanced chronic liver disease.

In this case report, we present a male patient who arrived at the hospital for the first time at the age of 8 with giant keloids in both ears and diagnosed by the dermatology and Plastic Surgery as having the “Disease of Jorge Lobo”, which is a fungal infection due to the story of the endemic characteristics. After the first surgical intervention, he received guidance from the team for keloids and left the hospital using elastic mesh and a request to change the place where he lived to reduce his contact with the fungi. Fourteen years later, the patient returned to the Plastic Surgery Service having even larger keloids in both ears, twice the size than the first time. We did the second surgical intervention to remove it, but with the patient’s commitment that he would correctly comply with the guidelines determined by the surgical team. After finishing all the steps and a post-operative for the case, we observed the satisfaction and the increase of the patient’s mood, happier and without the embarrassment of that physical defect.

Purpose: To investigate the prognostic impacts of a combined clopidogrel-metabolizing genotypes CYP 2C19 (+ or -)*2/(+ or -)*17 on patients with acute coronary syndrome (ACS). Population and methods: Prospective, longitudinal study of 95 patients admitted for ACS to a single coronary care unit. Patients less than 75 years of age, who survived hospitalization and to whom clopidogrel was prescribed, were included. CYP2C19 genotyping was performed at dis- charge. For analysis, the patients were grouped as follows: Group A ([+]*2/[+]*17) n = 8;Group B ([+]*2/[-]*17) n = 18;Group C ([-]*2/[+]*17) n = 27;and Group D ([-]*2/[-]*17) n = 42. Platelet function was assessed by an ADP platelet aggregation test using a commercially available kit. The primary end-point was a composite of mortality or readmission for ACS. The median time of follow-up was 136.0 (79.0 - 188.0) days. Results: The mean age of the study patients was 59.9 ± 10.7 years, and 83.2% were male. The allele frequencies of CYP2C19*2 and CYP2C19 *17 were 14.2% and 20%, respectively. Both allele frequencies were in Hardy Weinberg equilibrium. The patient groups were homogenous for demographic data, cardiovascular risk factors, GRACE and CRUSAde bleeding scores, left ventricular ejection fraction, and coronary anatomy. ADP platelet aggre-gation was similar for all groups (respective rates for groups A, B, C, D were 17.5 U (10.3 – 18.7) vs 20.0 U (17.3 – 26.8) vs 16 U (12 – 19) vs 12 U (8 – 22), p = 0.4). Event-free survival was significantly lower for group B (respective rates for Groups A, B, C, D were 87.5% vs 68.8% vs 96.3% vs 92.5%;p = 0.02). By multivariate Cox regression analysis, the CYP2C19 (+)*2/(-)*17 diplotype was an independent predictor of outcome, conferring a 5.2-fold higher adjusted risk for the composite endpoint than the others diplotypes. Conclusion: In our study, patients with the intermediate plus non-ultrarapid clopidogrel-metabolizing genotype ([+]*2/[-]*17) had a significantly poor medium-t

The objective of this study was to characterize and verify the in vitro antitumor activity of essential oils (EOs) extracted from the leaves and flowers of Callistemon viminalis. The EOs were extracted by hydrodistillation using a modified Clevenger apparatus. The identification and quantification of constituents were performed on a gas chromatograph coupled to a mass spectrometer and a gas chromatograph with a flame ionization detector. The antitumoral activity was evaluated by a colorimetric assay (MTS) using different cell lines derived from human tumors (breast, lung, glioblastoma, and melanoma). The major constituents of the EOs of leaves and flowers were similar, only quantitative differences being observed. The compounds 1,8-cineole, α-pinene and α-terpineol were found in concentrations of 50.4%, 25.8% and 8.7% in the EOs obtained from the leaves and 48.8%, 24.5% and 3.9% in the EOs obtained from the flowers, respectively. The cytotoxic activity of the EOs was observed only in melanoma cultures (HT144). Cultures treated for 48 h with EOs from leaves and flowers (200 μg·mL-1) reduced the viability by 40% and 25%, respectively. Thus, the antiproliferative activity of the EO from leaves was more pronounced than the EO from flowers in cells derived from melanoma.

Background: Alzheimer’s disease is a progressive and neurodegenerative disorder characterized by deterioration of brain functions. Psychosocial interventions such as music and photographic stimuli may contribute to cognitive and sensory exercise or rehabilitation. Objective: Evaluate musical and photographic stimuli in elderly people with Alzheimer’s disease. Methods: It is an uncontrolled clinical trial, before-after type, eleven subjects composing the sample. Participants were submitted to Katz Index, Autobiographical Memory Test, GDS-15, Mini-Mental State Examination. The collection instruments were used on the first and last day of intervention, individually. There were 2 sessions in the week with duration of 50 minutes totaling 20 sessions. Data were analyzed by descriptive and inferential statistics and as variables expressed as mean standard deviation. Results: There was a significant effect of cognitive activity (P , it was observed that a small advance (P = 0.05) of the daily life activities. With the analysis of GDS-15, it is verified that they are more effective for the increase of the previous self-estimation of the therapy (P = 0.94). In the application of the AMT, it is observed that there was a better recruitment of the memory for the neutral words. Conclusion: Musical and photographic stimuli had a positive effect on the cognitive level, daily life activities and autobiographical memory in seniors with Alzheimer’s disease.

The objectives of this study were to assess the safety and efficacy of intralesionally administered diclofenac in the treatment of cutaneous neurofibromas in patients with NF1. This was a proof-of-concept, prospective, safety and efficacy study of the effect of intralesionally administered diclofenac 25 mg/ml given once a week to 3 target cutaneous neurofibromas for 4 consecutive weeks. Overall, there was no significant change in neurofibroma size. During the study, some treated lesions developed signs of necrosis and fell off after a few weeks, but none of the control neurofibromas fell off. There were no significant changes in patient’s vital signs. A few adverse events occurred, mostly at the injection sites. During the study, some neurofibromas developed necrosis after the diclofenac injections and eventually detached from the patient. Overall, diclofenac was well tolerated, suggesting minimal systemic exposure, which required confirmation and further studies, including bioavailability analysis.
