Abstract: some individuals submitted to spine surgery will have unfavorable postoperative outcomes, regardless of the success of the technical procedure. this failure leads to an increase in morbidity and socioeconomic costs. also, it is known that psychosocial factors influence the subject's impression. in order to identify these factors, the search for prognostic predictors through screening instruments has been stimulated. however, selecting the most appropriate one may be difficult, as a large number of questionnaires already exist. the aspects addressed by these questionnaires include: functional incapacity, quality of life, satisfaction, pain, depression, mood swings and functional activity. this work reviews the special characteristics, indications and limitations of the instruments used to evaluate patients with spine disease.
Development and Implementation of Image-based Algorithms for Measurement of Deformations in Material Testing
Luigi Barazzetti,Marco Scaioni
Sensors , 2010, DOI: 10.3390/s100807469
Abstract: This paper presents the development and implementation of three image-based methods used to detect and measure the displacements of a vast number of points in the case of laboratory testing on construction materials. Starting from the needs of structural engineers, three ad hoc tools for crack measurement in fibre-reinforced specimens and 2D or 3D deformation analysis through digital images were implemented and tested. These tools make use of advanced image processing algorithms and can integrate or even substitute some traditional sensors employed today in most laboratories. In addition, the automation provided by the implemented software, the limited cost of the instruments and the possibility to operate with an indefinite number of points offer new and more extensive analysis in the field of material testing. Several comparisons with other traditional sensors widely adopted inside most laboratories were carried out in order to demonstrate the accuracy of the implemented software. Implementation details, simulations and real applications are reported and discussed in this paper.
What "best practice" could be in Palliative Care: an analysis of statements on practice and ethics expressed by the main Health Organizations
Gaia Barazzetti, Claudia Borreani, Guido Miccinesi, Franco Toscani
BMC Palliative Care , 2010, DOI: 10.1186/1472-684x-9-1
Abstract: The official documents by the most representative health organisations committed to the definition of policies and guidelines for palliative and end-of-life care had been considered. The documents were analysed through a framework of the components of end-of-life care derived from literature, which was composed of 4 main "areas" and of 12 "sub-areas".Overall, 34 organizations were identified, 7 international organisations, and 27 organisations operating on the national level in four different countries (Australia, Canada, UK and United States). Up to 56 documents were selected and analysed. Most of them (38) are position statements. Relevant quotations from the documents were presented by "areas" and "sub-areas". In general, the "sub-areas" of symptoms control as well as those referring to relational and social issues are more widely covered by the documents than the "sub-areas" related to "preparation" and to "existential condition". Indeed, the consistency of end-of-life choices with the patient's wishes, as well as completion and meaningfulness at the end of life is given only a minor relevance.An integrated model of the best palliative care practice is generally lacking in the documents. It might be argued that the lack of a fixed and coherent model is due to the relevance of unavoidable context issues in palliative care, such as specific cultural settings, patient-centred variables, and family specificity. The implication is that palliative care staff have continuously to adapt their model of caring to the specific needs and values of each patient, more than applying a fixed, although maybe comprehensive, care model.One of the main objectives of a culture is re-orienting death towards life[1]: each person's death threatens society's cohesion by casting a shadow on the feelings of safety and continuity on which every human being bases his/her life and finds support and consolation. For ages the "good death" reflected the community's religious beliefs, and the su

Open Journal of Stomatology (OJST) , 2013, DOI: 10.4236/ojst.2013.31001
Abstract:

The aim of this pilot study was to evaluate the shear bond strength of superficial bovine incisor dentin in different crown regions. Bonding was performed to the incisal, middle and cervical thirds of superficial bovine coronal dentin (n = 20) with a two-step etch-and-rinse adhesive (Optibond Solo Plus) and resin composite (Z100). Shear bond strength was evaluated at 24 h and failure modes of representative specimens wereobserved with FE-SEM. Non-parametric Kruskal-Wallis test with a significance level of 0.05 was used for data analysis. Mean shear bond strength values for the incisal, middle, and cervical thirds were 36.9 (3.1), 42.6 (2.6), and 37.1 (2.1) respectively with no significant differences evidenced between the crown thirds (p = 0.19). Observation of the failure mode of representative specimens demonstrated that specimens with high bond strength values exhibited predominantly mixed-type failures whereas low strength specimens exhibited adhesive failures between the dentin and adhesive. The absence of significant differences in shear bond strength between crown thirds indicate that, regardless of tubule orientation, any crown region can be used when superficial bovine incisor dentin is used for shear bond strength testing.

Abstract: A new 3D acquisition and processing procedure to map RGB, thermal IR and near infrared images (NIR) on a detailed 3D model of a building is presented. The combination and fusion of different data sources allows the generation of 3D thermal data useful for different purposes such as localization, visualization, and analysis of anomalies in contemporary architecture. The classic approach, which is currently used to map IR images on 3D models, is based on the direct registration of each single image by using space resection or homography. This approach is largely time consuming and in many cases suffers from poor object texture. To overcome these drawbacks, a “bi-camera” system coupling a thermal IR camera to a RGB camera has been setup. The second sensor is used to orient the “bi-camera” through a photogrammetric network also including free-handled camera stations to strengthen the block geometry. In many cases the bundle adjustment can be executed through a procedure for automatic extraction of tie points. Terrestrial laser scanning is adopted to retrieve the 3D model building. The integration of a low-cost NIR camera accumulates further radiometric information on the final 3D model. The use of such a sensor has not been exploited until now to assess the conservation state of buildings. Here some interesting findings from this kind of analysis are reported. The paper shows the methodology and its experimental application to a couple of buildings in the main Campus of Politecnico di Milano University, where IR thermography has previously been carried out for conservation and maintenance purposes.

Abstract: The purpose of this study was to determine the in vitro expansion and hatching rates of vitrified mouse blastocysts loaded into glass micro-capillaries (Brand - 5 μL). Early morning on day 4 of pregnancy, blastocysts were collected from donors, morphologically evaluated, and then allocated in three groups: Group 1 (Control): embryos were transferred into 100 μL of KSOM medium drops and in vitro cultured during 72 h; Groups 2 and 3: embryos initially exposed to the equilibration solution (PBSm + 10% EG + 10% PROH and 0.5% PVA) for 1 min, and then to vitrification solution (PBSm + 20% EG + 20% PROH + 0.5% PVA) for 30 sec. After that, blastocysts were loaded into glass micropipettes (GMP) or glass microcapillaries (GMC) and plunged into super-cooled liquid nitrogen (-200 °C). Embryo warming and cryoprotectant dilution were carried out into 500 μL droplets of PBSm supplemented with 0.25 M sucrose maintained at 37 °C. After 5 min embryos were transferred to 100 mL droplets of KSOM medium and cultured in vitro for 72 h. Blastocyst expansion rates after in vitro culture were 77% (138/177) and 74% (131/175), for blastocysts vitrified in GMP and GMC, respectively. Blastocyst hatching rate (control group) was 91% (134/146), which was higher than for embryos loaded in GMP 61% (108/177) and GMC 53% (93/175). ICM number in control group embryos contained 25.7 ± 2.5 cells and did not differ from the mean cell number observed in vitrified embryos loaded in GMP (24.2±2.3) or GMC (22.5±2.59). Regarding the trophoectoderm cell number, Group 1 embryos displayed 63.1±3.0 cells, and also not differ from the cell numbers of the embryos loaded into GMP (58.0±1.8) or GMC (58.0±.3.7). In conclusion, manufactured GMC (Brand ) tested in this study showed same efficiency as GMP for vitrification of mouse blastocysts.

Abstract: Pathogens in the soil or transmitted by seeds can reduce the stand of plants, affecting the yield of the crop. Furthermore, in the case of rice, the low temperature is a limiting factor in culture. The treatment of seeds with insecticides is an alternative to reduce the damage caused by pests incidents during the early stages of plant development and in some cases, may assist in the germination of seeds exposed to low temperatures. In this sense, the objective of this study was to evaluate the influence of seed treatment with insecticides in the physiological quality and yield of hybrid rice seeds, cv. Inov CL. For this, three experiments were conducted with treated seeds in different doses of thiamethoxam + lambda-cyhalothrin and fipronil totaling seven treatments, including the control (no product). In the first experiment, it was determined seed germination to 10°C, 13°C, 16°C, 20°C and 25°C. In the second experiment, it was assessed seed vigor through accelerated aging, cold test and emergency field. The third experiment was carried out into the field to observe the number of panicles m-2 and crop yield. It is concluded that treatment of hybrid rice seeds, cv. Inov CL with thiamethoxam + lambda-cyhalothrin and fipronil increases the germination percentage of seed and early seedling performance. Treatment of hybrid rice seeds, cv. Inov CL with thiamethoxam + lambda-cyhalothrin provides greater germination and early seedling performance compared to treatment with fipronil. Treatment of hybrid rice seeds, cv. Inov CL with thiamethoxam + lambda-cyhalothrin in dosages of 500 mL 100 kg-11 of seeds or 500 mL 45 kg-1 of seeds increases grain yield.

Abstract: The thiamethoxam acts as enhancer, allowing maximizing the expression of seed vigor. Isozymes are products of gene expression, highly influenced by the environment, because genes that control its expression are manifested in certain stages of development and in specific organs and tissues, or even under the action of certain stimulus. This study evaluated the isoenzyme expression in bean seedlings from seeds treated with thiamethoxam. Bean seeds were used, cultivar Pérola and IAPAR Siriri, submitted or not to drought stress. Seeds were treated at doses of thiamethoxam: 0, 1, 2, 3, 4 and 5 mL·kg-1 of seed. Isozymes were extracted from seedlings collected five days after sowing. We evaluated the expression of isoenzymes: Glutamate Oxalacetate transaminase (GOT), acid phosphatase (FAC), peroxidase (PO), Esterase (EST), malate dehydrogenase (MDH) and glutamate dehydrogenase (GTDH). Interpretation of the results was based on visual analysis of electrophoresis gels, considering the presence/absence and the intensity of each electrophoretic band. Bean seeds treated with thiamethoxam with doses up 3 mL·kg-1 of seed are higher germination untreated, even when submitted to drought stress. The expression of isozymes GOT, FAC, PO, EST, MDH and GTDH is not affected significantly in bean seedlings of Pérola and IPR Siriri under different doses of thiamethoxam with and without drought stress.
