The invasive spotted-wing Drosophila (Diptera, Drosophilidae) has been found in the city of São Paulo (Brazil)

The invasive spotted-wing Drosophila (Diptera, Drosophilidae) has been found in the city of São Paulo (Brazil). Drosophila suzukii (Matsumura, 1931), the cherry fly or spotted-wing Drosophila, a pest species from the Oriental and southeastern Palaearctic regions belonging to the melanogaster group, invaded the Nearctic and western countries of the Palaearctic regions late last decade (2008) and, more recently (2013), the southern Brazilian states of Rio Grande do Sul and Santa Catarina. Early in 2014 it was reared from blueberries produced in São Joaquim, state of Santa Catarina, that were bought at a São Paulo city grocery store. Despite being a cold-adapted species, after having arrived to the southeastern state of São Paulo, this invasive fly will probably expand its territory to other Brazilian states and South American countries through trade of cultivated soft skin small fruits, such as blueberries and strawberries, as well as naturally through the use of small wild fruits as breeding sites.

The Energy metabolism of China and India between 1971-2010: studying the bifurcation

This paper presents a comparison of the changes in the energetic metabolic pattern of China and India, the two most populated countries in the world, with two economies undergoing an important economic transition. The comparison of the changes in the energetic metabolic pattern has the scope to characterize and explain a bifurcation in their evolutionary path in the recent years, using the Multi-Scale Integrated Analysis of Societal and Ecosystem Metabolism (MuSIASEM) approach. The analysis shows an impressive transformation of China’s energy metabolism determined by the joining of the WTO in 2001. Since then, China became the largest factory of the world with a generalized capitalization of all sectors ―especially the industrial sector― boosting economic labor productivity as well as total energy consumption. India, on the contrary, lags behind when considering these factors. Looking at changes in the household sector (energy metabolism associated with final consumption) in the case of China, the energetic metabolic rate (EMR) soared in the last decade, also thanks to a reduced growth of population, whereas in India it remained stagnant for the last 40 years. This analysis indicates a big challenge for India for the next decade. In the light of the data analyzed both countries will continue to require strong injections of technical capital requiring a continuous increase in their total energy consumption. When considering the size of these economies it is easy to guess that this may induce a dramatic increase in the price of energy, an event that at the moment will penalize much more the chance of a quick economic development of India.

Censura gubernativa, Iglesia e inquisición en el siglo XVIII

Government censorship in Eighteenth Century Spain was another means of the Spanish Enlightenment policy. Until mid-century both powers of Church and State were balanced, from Charles III’s reign on the censorship of the Consejo de Castilla tried to control and restrict not only the traditional power of the Inquisition, but also the intellectual output of the country, either ideological -criticism on the Crown’s policy- or cultural-publishing religious Works. It is important to notice that many members of the elergy collaborated with the State in that task; and also that, after the French Revolution, the Inquisition regained its previous role. In the last decade of the Seventeenth century the irreconcilable clash between the advocates and the critics of the Inquisition became evident

Regulation of proliferation and differentiation of human fetal bone cells.

During the last decade, extensive research has been performed in the field of orthopedic medicine to develop cell-based therapies for the restoration of injured bone tissue. We previously demonstrated that human primary fetal bone cells (HFBCs) associated with porous scaffolds induced a bone formation in critical calvaria defect; however, the environmental factors regulating their behavior in culture have not been identified. HFBCs (human fetal femur,12 week development) were compared to marrow-derived human mesenchymal stem cells (HMSCs) for their capacity to proliferate and differentiate into osteoblasts under various culture conditions. When cultured in standard alphaMEM medium, PDGF and FGF-2 increased cell proliferation of both cell types. Investigation of the differentiating capacity of HFBCs and HMSCs in a normal culture medium indicated that HFBCs expressed higher expression levels of RUNX2, OSX, and osteogenic markers compared with HMSCs, while SOX9 was expressed at very low levels in both cells types. However, HMSCs, but not HFBCs enhanced osteoblastic markers in response to osteogenic factors. Surprisingly, BMP-2 with osteogenic factors increased cell numbers and reduced osteoblastic differentiation in HFBCs with the opposite effect seen in HMSCs. Associated with a higher expression of osteoblastic markers, HFBCs produced a higher calcified extra cellular matrix compared with HMSCs. Taken together, data presented in this study suggest that HFBCs have characteristics of osteoprecursor cells that are more advanced in their osteogenesis development compared with mesenchymal stem cells, making fetal cells an interesting biological tool for treatment of skeletal defects and diseases.

Sports-related chronic repetitive head trauma as a cause of pituitary dysfunction.

Traumatic brain injury (TBI) is recognized as a cause of hypopituitarism even after mild TBI. Although over the past decade, a growing body of research has detailed neuroendocrine changes induced by TBI, the mechanisms and risk factors responsible for this pituitary dysfunction are still unclear. Around the world, sports-especially combative sports-are very popular. However, sports are not generally considered as a cause of TBI in most epidemiological studies, and the link between sports-related head trauma and hypopituitarism has not been investigated until recently. Thus, there is a paucity of data regarding this important concern. Because of the large number of young sports participants with near-normal life expectancy, the implications of undiagnosed or untreated postconcussion pituitary dysfunction can be dramatic. Understanding the pathophysiological mechanisms and risk factors of hypopituitarism caused by sports injuries is thus an important issue that concerns both medical staff and sponsors of sports. The aim of this paper was to summarize the best evidence for understanding the pathophysiological mechanisms and to discuss the current data and recommendations on sports-related head trauma as a cause of hypopituitarism.

Affordable Housing in Iowa: Meeting New Challenges, 2007

Iowa faces a signifi cant challenge over the next decade. In the words of a recent report, “The state faces the danger of worker and skill gaps that could undermine its businesses, erode the earning power of its workers, and slow its economic growth.” (Iowa Works Campaign, 2006) Iowa’s economic and demographic stability depends on attracting new immigrants and slowing the departure of residents. Eroding housing affordability and quality will make this more difficult. Housing alone cannot solve the problem, but it must be part of the solution. This study examines trends in the state’s major housing markets, analyzes the achievements of housing programs in the recent past, and incorporates input from more than 80 housing experts across the state. The second part of this study (included on the attached CD) analyzes housing’s impact on the economy. We developed three major policy recommendations.

Nanopore detection of single molecule RNAP-DNA transcription complex.

In the past decade, a number of single-molecule methods have been developed with the aim of investigating single protein and nucleic acid interactions. For the first time we use solid-state nanopore sensing to detect a single E. coli RNAP-DNA transcription complex and single E. coli RNAP enzyme. On the basis of their specific conductance translocation signature, we can discriminate and identify between those two types of molecular translocations and translocations of bare DNA. This opens up a new perspectives for investigating transcription processes at the single-molecule level.

Recent developments in the use of isotope ratio mass spectrometry in sports drug testing.

According to the annual report of the World Anti-Doping Agency, steroids are the most frequently detected class of doping agents. Detecting the misuse of endogenously occurring steroids, i.e. steroids such as testosterone that are produced naturally by humans, is one of the most challenging issues in doping control analysis. The established thresholds for urinary concentrations or concentration ratios such as the testosterone/epitestosterone quotient are sometimes inconclusive owing to the large biological variation in these parameters.For more than 15 years, doping control laboratories focused on the carbon isotope ratios of endogenous steroids to distinguish between naturally elevated steroid profile parameters and illicit administration of steroids. A variety of different methods has been developed throughout the last decade and the number of different steroids under investigation by isotope ratio mass spectrometry has recently grown considerably. Besides norandrosterone, boldenone was found to occur endogenously in rare cases and the misuse of corticosteroids or epitestosterone can now be detected with the aid of carbon isotope ratios as well. In addition, steroids excreted as sulfoconjugates were investigated, and the first results regarding hydrogen isotope ratios recently became available.All of these will be presented in detail within this review together with some considerations on validation issues and on identification of parameters influencing steroidal isotope ratios in urine.

Profiling of counterfeit medicines by vibrational spectroscopy

Counterfeit pharmaceutical products have become a widespread problem in the last decade. Various analytical techniques have been applied to discriminate between genuine and counterfeit products. Among these, Near-infrared (NIR) and Raman spectroscopy provided promising results.The present study offers a methodology allowing to provide more valuable information fororganisations engaged in the fight against counterfeiting of medicines.A database was established by analyzing counterfeits of a particular pharmaceutical product using Near-infrared (NIR) and Raman spectroscopy. Unsupervised chemometric techniques (i.e. principal component analysis - PCA and hierarchical cluster analysis - HCA) were implemented to identify the classes within the datasets. Gas Chromatography coupled to Mass Spectrometry (GC-MS) and Fourier Transform Infrared Spectroscopy (FT-IR) were used to determine the number of different chemical profiles within the counterfeits. A comparison with the classes established by NIR and Raman spectroscopy allowed to evaluate the discriminating power provided by these techniques. Supervised classifiers (i.e. k-Nearest Neighbors, Partial Least Squares Discriminant Analysis, Probabilistic Neural Networks and Counterpropagation Artificial Neural Networks) were applied on the acquired NIR and Raman spectra and the results were compared to the ones provided by the unsupervised classifiers.The retained strategy for routine applications, founded on the classes identified by NIR and Raman spectroscopy, uses a classification algorithm based on distance measures and Receiver Operating Characteristics (ROC) curves. The model is able to compare the spectrum of a new counterfeit with that of previously analyzed products and to determine if a new specimen belongs to one of the existing classes, consequently allowing to establish a link with other counterfeits of the database.

Changing healthcare: stakeholder perceptions of the burden of chronic disease and the value of teams, measurements and communication.

Canadian healthcare is changing. Over the course of the past decade, the Health Care in Canada Survey (HCIC) has annually measured the reactions of the public and professional stakeholders to many of these change forces. In HCIC 2008, for the first time, the public's perception of their health status and all stakeholders' views of the burden and effective management of chronic diseases were sought. Overall, Canadians perceive themselves as healthy, with 84% of adults reporting good-to-excellent health. However, good health decreased with age as the occurrence of chronic illness rose, from 12% in the age group 18-24 to 65% for the population =65 years. More than 70% of all stakeholders were strongly or somewhat supportive of the implementation of coordinated care, or disease management programs, to improve the care of patients with chronic illnesses. Concordant support was also expressed for key disease management components, including coordinated interventions to improve home, community and self-care; increased wellness promotion; and increased use of clinical measurements and feedback to all stakeholders. However, there were also important areas of non-concordance. For example, the public and doctors consistently expressed less support than other stakeholders for the value of team care, including the use of non-physician professionals to provide patient care; increased patient involvement in decision-making; and the use of electronic health records to facilitate communication. The actual participation in disease management programs averaged 34% for professionals and 25% for the public. We conclude that chronic diseases are common, age-related and burdensome in Canada. Disease management or coordinated intervention often delivered by teams is also relatively common, despite its less-than-universal acceptance by all stakeholders. Further insights are needed, particularly into the variable perceptions of the value and efficacy of team-delivered healthcare and its important components.

Disseny i elaboració d'un gimnàs on-line

L’evolució que ha experimentat la societat, les grans ciutats, la industrialització i molts altres factors han modificat l’estil de vida de les persones accentuant-ne, irremediablement, el sedentarisme i l’abstinència de realitzar exercici físic. La pràctica esportiva i/o d’exercici físic realitzada sota les condicions recomanades pels professionals, és beneficiosa per millorar el nivell de salut o mantenir-lo en tot el possible, ja que provoca modificacions beneficioses sobre el metabolisme, el sistema cardiovascular i l’aparell locomotor. Lamentablement, l’hàbit de realitzar exercici físic no és comú en totes les persones, ja sigui per l’estil de vida que genera incompatibilitats d’horaris amb la feina, fills i familiars o bé per mandra o desgana d’haver d’aprofitar aquelles estones de temps lliure per dedicar-los al culte del cos i de la salut. Els efectes negatius que suposa una modalitat de vida sedentària per a la salut són notablement elevats, amb la qual cosa, cal buscar sistemes per augmentar l’ interès de la població per la pràctica de l’esport i l’activitat física. La creació d’aquest projecte neix de la idea d’unir el fet d’enginyar un mètode per incrementar l’interès de les persones per l’exercici físic amb els avenços tecnològics que s’han realitzat aquesta última dècada relacionats amb el desenvolupament web i multimèdia. A grans trets, la idea general d’aquest projecte es basa en el cas d’un gimnàs real i en actiu, amb necessitat de crear un portal web que serveixi alhora de pàgina web informativa i d’eina de gestió acadèmica del centre proporcionant certes funcionalitats als clients tot presentant-los una nova modalitat de realitzar exercici físic dirigit: realitzar-lo des de casa. Per desenvolupar tot el sistema informàtic que ho durà a terme, després de realitzar una recerca, anàlisi i elecció de les eines mitjançant les quals poder-ho realitzar, s’ha optat per crear l’entorn web mitjançant els llenguatges HTML i PHP en combinació amb els fulls d’estil CSS. Pel que fa a l’entorn de desenvolupament, s’ha utilitzat Notepad++ i com a entorn de proves, WAMP Server. Per últim, pel que fa a la transmissió del contingut multimèdia (vídeos de les sessions d’activitats) s’ha utilitzat Flash Media Interactive Server en combinació de Flash Media Live Encoder per codificar-ne el contingut. L’usuari final, des de qualsevol punt del planeta, podrà realitzar (sempre i quan disposi del temps i el material necessari i una connexió a Internet) en temps real i en directe les classes dirigides que es realitzen al centre. Tanmateix, també s’ha desenvolupat una botiga virtual on qualsevol persona podrà comprar-hi, entre d’altres coses relacionades amb la pràctica de l’exercici físic, tot el material necessari per realitzar qualsevol de les activitats que s’imparteixen al gimnàs i ho rebrà còmodament a casa. Aprofitar unes circumstàncies econòmiques adverses per generar una nova manera de captar clients proporcionant-los una alternativa econòmica, diferent, nova i original d’anar al gimnàs. Temps de crisis, temps d’oportunitats. Aquesta és la moralitat que pretén donar aquest projecte.

Defecto en la homeostasis del oxido nítrico. Mecanismo común subyacente de la insulino-resistencia, la hiperactividad simpática y la morbi-mortalidad cardiovascular [Defective nitric oxide homeostasis. Common underlying mechanism between insulin resistance, sympathetic overactivity and cardiovascular morbidity and mortality]

Obesity, insulin resistance and associated cardiovascular complications are reaching epidemic proportions worldwide and represent a major public health problem. Over the past decade, evidence has accumulated indicating that insulin administration, in addition to its metabolic effects, also has important cardiovascular actions. The sympathetic nervous system and the L-arginine-nitric oxide pathway are the central players in the mediation of insulin's cardiovascular actions. Based on recent animal and human research, we demonstrate that both defective and augmented NO synthesis represent a central defect triggering many of the metabolic, vascular and sympathetic abnormalities characteristic of insulin-resistant states. These observations provide the rationale for the use of pharmaceutical drugs releasing small and physiological amounts of NO and/or inhibitors of NO overproduction as a future treatment for insulin resistance and associated comorbidities.

Monitoring natural hazards

Few subjects have caught the attention of the entire world as much as those dealing with natural hazards. The first decade of this new millennium provides a litany of tragic examples of various hazards that turned into disasters affecting millions of individuals around the globe. The human losses (some 225,000 people) associated with the 2004 Indian Ocean earthquake and tsunami, the economic costs (approximately 200 billion USD) of the 2011 Tohoku Japan earthquake, tsunami and reactor event, and the collective social impacts of human tragedies experienced during Hurricane Katrina in 2005 all provide repetitive reminders that we humans are temporary guests occupying a very active and angry planet. Any examples may have been cited here to stress the point that natural events on Earth may, and often do, lead to disasters and catastrophes when humans place themselves into situations of high risk. Few subjects share the true interdisciplinary dependency that characterizes the field of natural hazards. From geology and geophysics to engineering and emergency response to social psychology and economics, the study of natural hazards draws input from an impressive suite of unique and previously independent specializations. Natural hazards provide a common platform to reduce disciplinary boundaries and facilitate a beneficial synergy in the provision of timely and useful information and action on this critical subject matter. As social norms change regarding the concept of acceptable risk and human migration leads to an explosion in the number of megacities, coastal over-crowding and unmanaged habitation in precarious environments such as mountainous slopes, the vulnerability of people and their susceptibility to natural hazards increases dramatically. Coupled with the concerns of changing climates, escalating recovery costs, a growing divergence between more developed and less developed countries, the subject of natural hazards remains on the forefront of issues that affect all people, nations, and environments all the time.This treatise provides a compendium of critical, timely and very detailed information and essential facts regarding the basic attributes of natural hazards and concomitant disasters. The Encyclopedia of Natural Hazards effectively captures and integrates contributions from an international portfolio of almost 300 specialists whose range of expertise addresses over 330 topics pertinent to the field of natural hazards. Disciplinary barriers are overcome in this comprehensive treatment of the subject matter. Clear illustrations and numerous color images enhance the primary aim to communicate and educate. The inclusion of a series of unique ?classic case study? events interspersed throughout the volume provides tangible examples linking concepts, issues, outcomes and solutions. These case studies illustrate different but notable recent, historic and prehistoric events that have shaped the world as we now know it. They provide excellent focal points linking the remaining terms in the volume to the primary field of study. This Encyclopedia of Natural Hazards will remain a standard reference of choice for many years.

Adaptation to marginal habitats

The ability to adapt to marginal habitats, in which survival and reproduction are initially poor, plays a crucial role in the evolution of ecological niches and species ranges. Adaptation to marginal habitats may be limited by genetic, developmental, and functional constraints, but also by consequences of demographic characteristics of marginal populations. Marginal populations are often sparse, fragmented, prone to local extinctions, or are demographic sinks subject to high immigration from high-quality core habitats. This makes them demographically and genetically dependent on core habitats and prone to gene flow counteracting local selection. Theoretical and empirical research in the past decade has advanced our understanding of conditions that favor adaptation to marginal habitats despite those limitations. This review is an attempt at synthesis of those developments and of the emerging conceptual framework.
