title: Continuous versus interrupted suture technique in microvascular anastomosis in rats

description: Abstract Purpose: To compare the continuous and interrupted suture technique on femoral artery on rats after vessel repair and 14 days after. Methods: Twenty rats were operated randomly divided into two group matched according to the suture technique used: interrupted or continuous. We performed a femoral anastomosis on the right femoral artery. We analyzed weight, arterial caliber, anastomosis time and patency after vessel repair and 14 days after. Results: There was no significant difference between groups in the weight (p=0.64), diameter of the femoral artery (p=0.95) and patency (p=1.00). The time spent in the anastomosis was 451 seconds in the continuous group and 718 seconds in the interrupted group, presenting significant difference (p&lt;0.01). Conclusion: The continuous suture technique shows a similar patency rates than interrupted technique, however with a shorter time to perform the anastomosis.

title: Industrial textile recycling and reuse in Brazil: case study and considerations concerning the circular economy

description: Abstract Textile products are present in all aspects of our lives and drive a significant part of the world economy. Issues related to enterprise competitiveness, sustainability, limitation of natural resources, environmental and social impacts are increasingly considered. In this context, the recovery and recycling of textile materials are essential. This study aimed to present an overview of the Brazilian textile and clothing industry, highlighting the mechanical and chemical recycling processes and reuse. We also discuss the reasons for importing textile waste, and considerations about circular economy concepts, correlating them to the key factors and obstacles involving industrial operation of textile recycling. The authors conducted technical visits to textile recycling industries in order to observe the production processes and identify their main challenges. Nevertheless, the initiatives show that Brazil is on track for industrial sustainability, following a global production trend.

title: La globalización y la política macroeconómica acentúan la financiarización y la fragilidad de las economías: el caso de México

description: Summary The predominant economic policies have promoted the financialization of Latin American economies, which has been to the detriment of the endogenous conditions of accumulation and has led the economy to depend on the behavior of exports and capital inflow, which is why they are placed in a context of high vulnerability. When these variables acted in a positive way, conditions of stability and certain growth were reached. By failing to act positively, imbalances in public finances and the external sector manifest themselves, destabilizing exchange rate parity, the capital market and slowing growth. Governments are reacting with restrictive monetary and fiscal policies, which further weaken economies. The Latin American economies and in particular the Mexican economy, which is the object of study, do not present prospects for growth towards the external market, given the slowdown in international trade, and the eventual protectionist policies that the new government will implement in the United States. There is also no prospect of inward growth, because economic liberalization and high levels of indebtedness prevent them from flexibilizing economic policy.

title: The bats of Rio Grande do Norte state, northeastern Brazil

description: Abstract Rio Grande do Norte is one of the smallest states in Brazil but has a rich diversity of ecosystems, including Caatinga vegetation, remnants of Atlantic Forest, coastal habitats, mangroves and large karstic areas with caves. However, its chiropteran fauna is little known, and the state contains conspicuous gaps of information on the occurrence and distribution of bats in Brazil. In order to reduce this information gap, based on a review of scientific literature and regional mammal collections, we list 42 species of bats, including new occurrences for 13 species and discussion on their conservation status. Results show that more than half (54%) of the recorded species are phyllostomid bats, and about one third of the bats in the state roosts in underground cavities. The Caatinga harbored the highest bat richness in the state, including the occurrence of four vulnerable species (Furipterus horrens, Lonchorhina aurita, Natalus macrourus and Xeronycteris vieirai). The Atlantic Forest needs to be more sampled, including mangroves, coastal habitats and areas of Caatinga in the central region of the state (Borborema highlands), which are virtually unsurveyed. Although the recent increase of studies on bats in the state, future studies should complement conventional mistnetting with active roost search and bioacoustical records in order to obtain better data for unraveling the bat fauna of Rio Grande do Norte.

title: THE DEBATE ABOUT CURRICULUM POLICY AND THE MEANING OF SUPERVISED INTERNSHIPS (1996-2006): AN ANALYSIS BASED ON DISCOURSE THEORY

description: ABSTRACT: This article describes the results of a research study about Brazil’s debate on curriculum and the meaning of supervised internships (1996-2006), considering the concepts of demands, articulations, and hegemony. We have worked with Ernesto Laclau’s discourse theory arguing that such a debate represents a discursive articulation field. We formulated questions like “Which demands are hegemonized in curriculum policies?” and “How the meanings of supervised internships are built through this debate?” The field of study is the National Association for Education Professionals Training (ANFOPE) and the Ministry of Education/National Council of Education (MEC/CNE). We created a method of analysis based on discourse theory in order to examine the aforementioned debate through the perspective of questioning/deconstructing discourses to reveal how hegemony operates. We found that the meanings of supervised internship result from articulatory practices between different demands produced during it, under the influence of conflictual debate surrounding knowledge, training models and the curriculum.

title: Rapid Transport of Deformation-Tuned Nanoparticles across Biological Hydrogels and Cellular Barriers

description: Nanoparticle (NP) size, shape and surface charge have proven to affect the interaction of nanoparticles with cells and within animals. However, whether NP elasticity affects transport across various barriers outside and inside the cell remains elusive. Here, we experimentally and theoretically demonstrated that NPs with appropriate elasticity displayed superior mucus penetration and higher epithelial cellular uptake than their softer and harder counterparts in mucosal tissue. It is unprecedented that these semi-elastic NPs even displayed approximately 17-fold enhanced diffusivity than NPs with small size in mucus. Preliminary results further showed that semi-elastic NPs could effectively deliver the anticancer drug doxorubicin in rat orally. Molecular simulations and super-resolution microscopy revealed that the softer NPs deformed easily, which rendered them to accommodate with and adhere to the mucus fiber, thus showing the lowest permeation.<br>

title: ADDITIONAL LANGUAGE TAUGHT IN PUBLIC SCHOOLS: DISCUSSION FROM AN INTERCULTURAL SCENARIO

description: ABSTRACT: This article aims to discuss partial data of a more comprehensive survey that analyzed the offer of additional languages in the primary education, in a scenario historically characterized by intercultural aspects: the Micro-region of Blumenau, Santa Catarina. Previous studies have pointed the presence of immigration languages in the region, which justifies the need of tracing a profile of languages offered in the school curriculum of the public education system. The methodological procedures included a data survey through questionnaire in the fifteen cities that compose the region. From this survey, it was possible to recognize each city situation regarding the languages offered in schools and the latest local linguistic policies. The records’ analysis shows small investment in the immigration languages still present in the micro-region, as well as the need to discuss the role of the school while facing contemporary multilingualism.

title: Short-term Creep Properties and Fracture Surface of 18 Ni (300) Maraging Steel Plasma Nitrided

description: Plasma nitriding of a solution annealed and aged 300 grade maraging steel was studied aiming to increase the creep resistance. The surface microhardness reached 1,140 HV, producing 50 µm layer composed of ε-Fe3N and γ'-Fe4N nitrides at the uppermost sample layer. The inner core remained unaltered presenting typical plate-like martensite microstructure of maraging steels with average microhardness of 604 HV. Surface RMS roughness in the nanometric scale increase from 52 nm to 71 nm. The continuous layer of iron nitrides seems to behave as a barrier for oxidation and for inward oxygen diffusion improving the creep resistance by reducing the steady-state creep rate (εs) in 52-65% when compared with the literature results. Dominant creep mechanism is controlled by dislocations climb. Fracture surfaces of specimens presented ductile failure consisting of equiaxed and bi-modal dimples in the fibrous zone surrounded by 45º shear lip. Nitrided sample presented a reduced ductility, associated to the hard surface layer.

title: Oral pigmentations in Laugier-Hunziker syndrome: a case report and review of diagnostic criteria

description: ABSTRACT Laugier-Hunziker syndrome (LHS) is a rare mucocutaneous disorder, of unknown etiology, characterized by multiple hyperpigmented macules, dispersed mostly on the oral mucosa, occasionally associated with longitudinal ridging of the nails. The diagnosis requires exclusion of other conditions, such as Addison's disease and Peutz-Jeghers syndrome. We report a case of a 34-year-old male patient, presenting with hyperpigmented macules on the lips, buccal mucosa and palate, as well as mild dark striations on toenails. After careful clinical and laboratorial investigations, the diagnosis of LHS was established. Given the lack of aesthetic complaints and symptoms, no treatment was necessary.

title: A GENERIC TACTICAL PLANNING MODEL TO SUPPLY A BIOREFINERY WITH BIOMASS

description: ABSTRACT The supply chains which bring biomass to biorefineries play a critical role in biofuel production. Optimization models can help decision makers to design more efficient chains and minimize the cost of biomass delivered to the refineries. This article based on a French national research project on biomass logistics considers one refinery, able to process several crops and several parts of the same crop, over a one-year horizon divided into days or weeks. A network model and a data model are first developed to let the decision maker describe the supply chain structure and its data, without affecting the underlying mathematical model. The latter is a mixed integer linear program which combines for the first time various features, either original or tackled separately in the literature. Knowing the refinery demands, it determines the activity levels in the network (amounts harvested, baled, transported, stored, etc.) and the required equipment, in order to minimize a total cost including harvesting costs, transport costs and storage costs. Numerical evaluations based on real data show that the proposed model can optimize large supply chains in reasonable running times.

title: Frequency and carbapenems susceptibility profile of non-fermenting Gram-negative bacilli isolated from clinical samples between 2007 and 2012

description: ABSTRACT Introduction: One of the major problems in health services is the occurrence of healthcare-associated infections (HAIs) by microorganisms resistant to various antimicrobials. Objectives: To describe the frequency and susceptibility profile of Pseudomonas aeruginosa and Acinetobacter baumannii to carbapenems in the hospital from Fundação Santa Casa de Franca, São Paulo, Brazil. Methods: The susceptibility of P. aeruginosa and A. baumannii to carbapenems from 304 clinical isolates between 2007 and 2012 was retrospectively analyzed from a microbiology database at the clinical laboratory of the hospital of Fundação Santa Casa de Franca, São Paulo, Brazil. Results: From isolated and identified strains, 236 (5.3%) P. aeruginosa were susceptible to imipenem (2007 - 69.6% to 2012 - 41.7%) and meropenem (2007 - 63.3% to 2012 - 25%). In addition, all 68 (1.7%) A. baumannii isolates were susceptible to both antibiotics. Conclusion: A. baumannii resistance to carbapenems was not identified; however, there was a decrease in susceptibility to carbapenems over the years for P. aeruginosa.
