Authors: Lin Jixiang , Wang Yingnan , Qi Mingming , Li Xiaoyu , Yang Chunxue , Wang Yongcui , Mu Chunsheng
Published: May 2016

Timely harvest is critical to achieve maximum seed viability and vigour in agricultural production. However, little information exists concerning how to reap the best quality seeds of Leymus chinensis, which is the dominant and most promising grass species in the Songnen Grassland of Northern China. The objective of this study was to investigate and evaluate possible quality indices of the seeds at different days after peak anthesis. Seed quality at different development stages was assessed by the colours of the seed and lemmas, seed weight, moisture content, electrical conductivity of seed leachate and germination indices. Two consecutive years of experimental results showed that the maximum seed quality was recorded at 39 days after peak anthesis. At this date, the colours of the seed and lemmas reached heavy brown and yellow, respectively. The seed weight was highest and the moisture content and the electrical conductivity of seed leachate were lowest. In addition, the seed also reached its maximum germination percentage and energy at this stage, determined using a standard germination test (SGT) and accelerated ageing test (AAT). Thus, Leymus chinensis can be harvested at 39 days after peak anthesis based on the changes in parameters. Colour identification can be used as an additional indicator to provide a more rapid and reliable measure of optimum seed maturity; approximately 10 days after the colour of the lemmas reached yellow and the colour of the seed reached heavy brown, the seed of this species was suitable for harvest.
Depletion of kinesin-12, a myosin-IIB-interacting protein, promotes migration of cortical astrocytes

Published: May 2016

Kinesin-12 (also named Kif15) participates in important events during neuronal development, such as cell division of neuronal precursors, migration of young neurons and establishment of axons and dendritic arbors, by regulating microtubule organization. Little is known about the molecular mechanisms behind the functions of kinesin-12, and even less is known about its roles in other cell types of the nervous system. Here, we show that kinesin-12 depletion from cultured rat cortical astrocytes decreases cell proliferation but increases migration. Co-immunoprecipitation, GST pulldown and small interfering RNA (siRNA) experiments indicated that kinesin-12 directly interacts with myosin-IIB through their tail domains. Immunofluorescence analyses indicated that kinesin-12 and myosin-IIB colocalize in the lamellar region of astrocytes, and fluorescence resonance energy transfer analyses revealed an interaction between the two. The phosphorylation at Thr1142 of kinesin-12 was vital for their interaction. Loss of their interaction through expression of a phosphorylation mutant of kinesin-12 promoted astrocyte migration. We suggest that kinesin-12 and myosin-IIB can form a hetero-oligomer that generates force to integrate microtubules and actin filaments in certain regions of cells, and in the case of astrocytes, that this interaction can modulate their migration.
Cities Are Physical Too: Using Computer Vision to Measure the Quality and Impact of Urban Appearance
Authors: Naik Nikhil , Raskar Ramesh , Hidalgo César A.
Published: May 2016

For social scientists, developing an empirical connection between the physical appearance of a city and the behavior and health of its inhabitants has proved challenging due to a lack of data on urban appearance. Can we use computers to quantify urban appearance from street-level imagery? We describe Streetscore: a computer vision algorithm that measures the perceived safety of streetscapes. Using Streetscore to evaluate 19 American cities, we find that the average perceived safety has a strong positive correlation with population density and household income; and the variation in perceived safety has a strong positive correlation with income inequality.
Measuring the Effect of Blended Learning: Evidence from a Selective Liberal Arts College
Authors: Swoboda Aaron , Feiler Lauren
Published: May 2016

We compare introductory microeconomics courses that employ a blended learning approach to more traditional control courses at a selective liberal arts college. The blended learning courses required students to complete online homework and watch video lectures before problem-based class sessions, while the control courses used paper homework and primarily traditional lecturing. We use the Test of Understanding in College Economics to measure improvement and use the Student Opinion Survey to control for students' self-reported effort and amount of importance placed on the test. We find that students in the blended courses improve more than those in traditional courses.
State Capacity and American Technology: Evidence from the Nineteenth Century
Authors: Acemoglu Daron , Moscona Jacob , Robinson James A.
Published: May 2016

Robert Gordon's The Rise and Fall of American Economic Growth compellingly shows how technical innovation, stimulated by the country's institutions, has radically improved the living standards of the citizens of the US. We conduct an empirical investigation of the impact of the capacity of the US state, as proxied by the presence of post offices, on innovation. We show that there is a strong association between the number of post offices in a county and patenting activity. Our evidence suggests that part of story of US innovation is the capacity and reach of the US state.
Winter Is Coming: Robert Gordon and the Future of Economic Growth
Authors: Clark Gregory
Published: May 2016

This comment assesses the claim of The Rise and Fall of American Growth that for coming decades, growth in US TFP will continue the disappointing pace of the last decade. While predicting future technological advance is difficult, there are indications that Gordon may actually be too optimistic on future TFP growth. The share of output from manufacturing, which still generates the majority of R&D expenditures, and has historically more rapid TFP growth, will continue to fall. There are substantial obstacles to rapid TFP advance in much of the rest of the economy: construction, transport, health care and other services.
Patent Licensing, Technology Transfer, and Innovation
Authors: Lemley Mark A. , Feldman Robin
Published: May 2016

Traditional justifications for patents are based on direct or indirect contribution to product creation. Non-practicing entities (NPEs) might provide such innovation, either directly, through working the patent or transfer of technology to others who do, or indirectly, when others copy. Available evidence suggests, however, that ex post licensing demands from NPEs do not normally involve these activities. Some have argued that patents are valuable without01/technology transfer because the ability to exclude may drive commercialization that would not otherwise occur. We demonstrate that even if commercialization theories sometimes justify patent protection, they cannot justify most NPE lawsuits or licensing demands.
Infrastructure, Incentives, and Institutions
Authors: Ashraf Nava , Glaeser Edward L. , Ponzetto Giacomo A. M.
Published: May 2016

Expensive infrastructure is ineffective if it doesn't travel the last mile. In nineteenth-century New York and modern Africa, disease has spread when urbanites chose not to use newly built sanitation infrastructure to save money. Either subsidies or Pigouvian fines can internalize the externalities that occur when people don't use sanitation infrastructure, but with weak institutions subsidies generate waste and fines lead to extortion. Our model illustrates the complementarity between infrastructure and institutions and shows how institutional weaknesses determine whether fines, subsidies, both or neither are optimal. Contrary to Becker (1968), the optimal fine is often mild to reduce extortion.
Paid Parental Leave Laws in the United States: Does Short-Duration Leave Affect Women's Labor-Force Attachment?
Authors: Byker Tanya S.
Published: May 2016

I analyze the effects of short-duration paid parental leave on maternal labor supply. Using monthly longitudinal data from the Survey of Income and Program Participation, my event-study research design estimates impacts of paid leave laws in California and New Jersey on women's labor-force outcomes around childbirth. I find that paid leave laws are associated with a substantial increase in labor-force attachment in the months directly around birth. While US-style short-duration leave is unlikely to change prolonged exits from the labor force, my findings imply that paid leave laws induce some women stay more attached to jobs, particularly low-skill women.
Case Report: Cervical chondrocalcinosis as a complication of Gitelman syndrome
Authors: Iqbal Zahra , Mead Paul , Sayer John A.
Published: May 2016

Gitelman syndrome is an inherited tubulopathy leading to a hypokalaemic metabolic alkalosis with hypomagnesaemia and hypocalciuria. Most cases are due to mutations in SLC12A3, encoding the apical thiazide sensitive co-transporter in the distal convoluted tubule. Musculoskeletal effects of Gitelman syndrome are common, including muscle weakness, tetany and cramps. Chronic hypomagnesaemia can lead to chondrocalcinosis, which often affects knees but can affect other joints. Here we present a case of Gitelman syndrome complicated by cervical chondrocalcinosis leading to neck pain and numbness of the fingers. Treatments directed at correcting both hypokalaemia and hypomagnesaemia were initiated and allowed conservative non-surgical management of the neck pain. Recognition of chondrocalcinosis is important and treatments must be individualised to correct the underlying hypomagnesaemia.
Responsible court in the global world – managerism or managerialism
Authors: Morawska Sylwia , Banasik Przemysław
Published: May 2016

One can look at the improvement of the effectiveness and efficiency of the justice system from three perspectives: macro, mezo, and micro. After all, the general goal is to enhance the effectiveness and efficiency of the justice system as a whole (the macro perspective), the courts (the mezo scale), and court proceedings  (the micro scale). The need to improve the effectiveness and efficiency of the justice system was noticed in the Strategy of modernization of justice  in Poland in the years 2014–2020 prepared by the Ministry of Justice incorporates the three abovementioned perspectives. From the perspective of this paper, emphasis has been placed on courts. The Strategy, as a matter of fact, assumes that the improvement of  the effectiveness and efficiency of courts may occur by introducing a model of management based on the idea of “managerialism” to run them. Effective and efficient courts, just like the proceedings they operate, are particularly important in the face of globalization, regulatory arbitration, as well as forum shopping. Based on a case study, this paper outlines the results of an innovative pilot project of implementing management methods of running common courts, and sets out to answer the question of the extent to which the state of institutional development of courts allows one to employ good practices in courts already successful in the world of business. During the pilot study, in 60 selected regional, district, and appellate courts, with the support of external experts, „good practices” were implemented to serve as management enhancements (Final report…, 2014..). The results of the pilot study prove that the level of institutional development of courts determines the possibility of introducing good management practices that have already been approved in the world of business. This situation is further complicated by the diverse level of institutional development among courts. The type of a given court (its size, regional, district, appellate) may impact the possible upgrade of the maturity of the way a given practice functions. Also, not all business practices are eligible for implementation, given the different level of managers’ competence, as well as the frequently clear process of taking on the management staff.

Non–rinse skin cleansers: the way forward in preventing incontinence related moisture lesions?
Authors: Harries F. J. , Begg P. A.
Published: May 2016

Objective:

The use of non-rinse skin cleansers in the care of patients who are at risk of tissue breakdown is not new within the National Health Service (NHS). Back to the Floor Continence Care Rounds (introduced in 2012 to facilitate bedside continence care education) at University Hospitals Birmingham had identified that in the current climate of austerity and efficiency savings, the use of non-rinse cleanser was being randomly rationed. Our objective was to determine whether the introduction of a smaller tube of non-rinse cleanser with targeted education would improve usage and ultimately improve the skin of incontinent patients.

Method:

There were five clinical areas randomised into two groups. In group 1 three clinical areas were provided with targeted education and new sizes of tubes of non-rinse skin cleanser. In group 2, the two remaining clinical areas acted as control groups, one receiving targeted education only and the remaining had no education or new sized tubes. The incidence of incontinence associated moisture lesions from each clinical area was monitored for 13 weeks pre and post study period.

Results:

The in-depth study undertaken at University Hospitals Birmingham, over a 6-month period, confirmed a trend in staff committing to the ethos of prudency, and in turn compromising the use of the most effective treatment and prevention of incontinence associated moisture lesions. The ability of the Trust staff to recognise and respond to a change in practice and the responsiveness of a commercial provider to the proposed new methodology has resulted in a significant reduction in incontinence associated moisture lesions across the trust. The clinical areas included in the study demonstrated a 70–76.9% reduction in moisture lesion incidence compared to an 8.3–13.6% reduction in the control groups.

Conclusion:

The results strongly suggest that a reduction in incontinence associated moisture lesions can be achieved by a simple change in nursing regime. The combination of solid education provision, alongside a more appropriate size of product, has demonstrated significant patient benefit, greater adherence in practice and a reduction in waste. The integrity of the patients' tissue was preserved and staff were satisfied with their input and the patients' progress. The outcomes of this study will have an impact on patient benefit and on the efficiency for trusts resulting in greater patient satisfaction and a more appropriate use of limited resources.

Declaration of interest:

SCA provided 20ml tubes of TENA Wash Cream free of charge and the TENA Nurse Advisor for support during the education provision element of the study.

El sentido del positivismo jurídico (II): el positivismo jurídico prescriptivo como un derecho humano
Authors: Campbell Tom
Published: May 2016

Continúa aquí defendiéndose el iuspositivismo "prescriptivo" o "ético" ya esbozado en la primera parte de este artículo (Doxa, núm 25): entender el iuspositivismo como una teoría normativa (no conceptual ni descriptiva) sobre la forma del Derecho como gobierno de reglas claras y precisas empíricamente aplicables sin recurrir a opiniones morales. Ahora se muestra cómo lo anterior constituye un derecho humano vinculado a la democracia y a la igualdad: los derechos humanos incorporan la idea del imperio de la ley, pero de la ley positiva en ese sentido formal. En consecuencia, la tarea de articular los derechos humanos es de los gobiernos y los parlamentos, no de los tribunales ni de la Constitución, siendo el control judicial sustantivo sobre las leyes algo básicamente antidemocrático. Por último, la disputa conceptual entre el iuspositivismo incluyente y el excluyente debe reformularse como una disputa moral y política sobre qué órgano ha de determinar el contenido de las reglas y sobre si la regla de reconocimiento debe o no contener criterios morales.
La doctrina de la revisión judicial y la obligación de obedecer el Derecho
Authors: William Idowu W.
Published: May 2016

El autor estudia la conexión entre la revisión judicial de las leyes y el problema de la obediencia al Derecho. En particular, intenta mostrar de qué manera un análisis acerca de la doctrina de la revisión judicial, contribuye a resolver algunas cuestiones relacionadas con el problema de la obediencia al Derecho. En su opinión "la obligación de obedecer el Derecho deriva de la conformidad de una regla jurídica con una norma externa [...] el contenido moral de la ley define o determina si se genera una obligación de obedecer el Derecho". Partiendo del análisis de la revisión judicial a la luz de la idea de obligación jurídica, el autor concluye que "no hay obligación prima facie de obedecer una ley perniciosa o injusta cuando existen limitaciones a la autorización para crear leyes". La obligación de obedecer el Derecho es moral, lo que quiere decir que "deriva del contenido del Derecho y, por tanto, que es externa al mismo".

Wolff entre autoridad y autonomía: un análisis de la concepción voluntarista de la autonomía como autolegislación y de sus consecuencias respecto de la tesis de la incompatibilidad conceptual entre autoridad y autonomía
Authors: Iosa Juan
Published: May 2016

El trabajo distingue entre dos concepciones de la autonomía moral —como autolegislación y como juicio propio— presentes en In Defense of Anarchism, de Wolff. Seguidamente examina la particular comprensión wolffiana de la idea de autonomía como autolegislación: el voluntarismo. Se muestra que Wolff adopta esta tesis como consecuencia de su rechazo a la viabilidad de la pretensión kantiana de fundar la ley moral sobre bases a priori. Considero que presentar los argumentos de Wolff en contra de Kant es un buen medio tanto para determinar los contornos de la concepción voluntarista de la autonomía como autolegislación como para explicitar los compromisos que su adopción implica. Por último se intenta mostrar que desde una concepción voluntarista de la autonomía como autolegislación no puede sostenerse coherentemente la tesis de la incompatibilidad conceptual entre autoridad y autonomía. Si la democracia directa y por unanimidad es, como sostiene Wolff, un tipo de autoridad, entonces a partir del voluntarismo hay al menos un caso en que podemos hablar con propiedad de autoridad legítima.

Published: May 2016

A revisão da literatura é uma etapa chave da pesquisa em qualquer campo da ciência. Na área de logística e transportes se destaca o uso da Revisão Sistemática da Literatura (RSL). Este método apresenta um processo replicável e auditável de execução, mas não está livre do viés e da subjetividade do pesquisador e de falhas em sua execução que podem comprometer os resultados da revisão. Diante destas dificuldades, o trabalho propõe a adoção de critérios de avaliação da qualidade na condução da RSL de forma a identificar falhas e corrigi-las. Para demonstrar a aplicabilidade da proposta, três estudos de caso na área de logística e transportes são avaliados. A aplicação permitiu identificar falhas na execução da RSL e apontar formas de correção das mesmas. Ressalta-se que os critérios propostos são úteis também para a avaliação da qualidade de revisões narrativas da literatura.

FLUCTUATION EFFECT OF EQUILIBRIUM MOISTURE CONTENT OF LOW SUBGRADE UNDER HIGH GROUNDWATER LEVEL IN HOT AND HUMID CLIMATIC REGIONS
Authors: Yun Que , Jiabin Wu
Published: May 2016

In order to reveal the fluctuation effect of equilibrium moisture content of low subgrade in hot and humid climatic regions, the effect of temperature on the fluctuation of the equilibrium moisture content of subgrade was analysed. Taking the typical climate and the subgrade soil in Fujian province as an example, three technological methods - theoretical analysis, numerical simulation and indoor simulation experiment - were adopted in the investigation of the fluctuation effect of equilibrium moisture content of subgrade. The results show that, computing results from the formula of the equilibrium moisture content of subgrade, the numerical simulation results are closer to each other in consideration of the temperature effect. The test results can not reflect the relationship between the equilibrium moisture content and the height of embankment. The maximum fluctuation range of the equilibrium moisture content of the cement concrete pavement is less than 2 percent in Fujian area, and this phenomenon presents the effect of the moist-hot climate on the equilibrium moisture content. Equilibrium moisture content presents a declining trend with the increment of the temperature and the compactness. So, if matric potential considering temperature indirectly reflects the influence of thermal potential, then the equilibrium moisture content of low subgrade under high groundwater level can be estimated approximately. The fluctuation range of equilibrium moisture content in different layers of subgrade can be reduced effectively with the increment of the roadbed compaction degree.

Published: May 2016

The aim of the research was to carry out a hydraulic design of rowing/sculling and paddlingsimulator. Nowadays there are two main approaches in the simulator design. The first one includesa static water with no artificial movement and counts on specially cut oars to provide the sameresistance in the water. The second approach, on the other hand uses pumps or similar devices toforce the water to circulate but both of the designs share many problems. Such problems areaffecting already built facilities and can be summarized as unrealistic feeling, unwanted turbulentflow and bad velocity profile. Therefore, the goal was to design a new rowing simulator that wouldprovide nature-like conditions for the racers and provide an unmatched experience. In order toaccomplish this challenge, it was decided to use in-depth numerical modeling to solve the hydraulicproblems. The general measures for the design were taken in accordance with space availability ofthe simulator´s housing. The entire research was coordinated with other stages of the constructionusing BIM. The detailed geometry was designed using a numerical model in Ansys Fluent andparametric auto-optimization tools which led to minimum negative hydraulic phenomena anddecreased investment and operational costs due to the decreased hydraulic losses in the system.

Published: May 2016

Coloration of cotton fabric in one step via in situ deposition of manganese oxide or cobalt oxide nanoparticles, using microwave techniques, was performed. The structure and surface morphology of the obtained nanoparticles were studied by x-ray diffraction analysis and transmission electron microscopy (TEM). The cobalt oxide nanoparticles had a nanotube-like shape, with a length of 100–200 nm and a diameter of ∼58 nm, whereas manganese oxide nanoparticles had a linear structure of nanorods with a diameter of 50–55 nm and a length of 70-80 nm. Treated cotton fabrics were characterized by scanning electron microscopy (SEM) and the amount of nanoparticles deposited was quantitatively analyzed by SEM coupled with high energy dispersive x-ray (XRD) analysis. The fastness properties of dyed cotton fabrics containing these nanoparticles were evaluated.

Published: May 2016

The purpose of this research was to evaluate clothing ventilation designs for their ability to reduce heat stress incurred during firefighting activities. Ventilation applications were implemented on structural turnout suits, including both active and passive systems, to determine the benefit of ventilation towards heat loss. A total of five different designs were evaluated on a sweating manikin for thermal and evaporative resistance. From these measurements, a predicted total heat loss (THL) was calculated for each design and compared back to a control suit with no ventilation. A significant improvement in heat loss was measured, specifically, with the maximum open ventilation design. Overall, ventilation designs in structural firefighter turnout gear showed a statistically significant increase in heat loss improvement for the wearer.
EDUCAÇÃO INCLUSIVA: A IMPORTÂNCIA DA INTERAÇÃO NO ESPAÇO ESCOLAR ENTRE DOCENTE E ESTUDANTE SURDO

O artigo tem por objetivo investigar a importância da interação afetiva entre docente e estudante viabilizada por aspectos da educação inclusiva da pessoa surda no contexto escolar. A pesquisa tem como foco a abordagem qualitativa por apresentar métodos exploratórios e descritivos, sendo empregado o estudo de caso, o qual foi realizado numa escola pública do interior do estado de Rondônia. Os participantes foram sete adolescentes surdos na faixa etária dos catorze aos dezoitos anos e oito docentes que lecionam em turmas de ensino médio que continham estudantes surdos matriculados. Como procedimento estratégico aplicou-se um questionário semiestruturado com indagações de cunho fechado e aberto. Portanto, obteve-se a conclusão de que não há uma interação entre docente e estudante adolescente surdo no contexto escolar, visto que a relação pedagógica não é interativa. Cujo fator preponderante é a falta de comunicação no ambiente de ensino entre as pessoas ouvintes com as pessoas surdas. Ocorrido principalmente pelo desconhecimento da Libras pelo grupo dominante, tornando a relação distante, com pouca afetividade e motivação para o processo de ensino-aprendizagem.http://dx.doi.org/10.14572/nuances.v27i1.3440

A necessidade de compreender o indivíduo em sua totalidade, histórico e socialmente constituído, rompendo com a dicotomia corpo/mente, tal como a psicologia histórico-cultural defende, é importante para a formação de professores de qualquer componente curricular da educação formal. Na educação física, cujo objeto é a cultura corporal, essa compreensão é fundamental, pois o licenciado atuará na escola, como professor e profissional da saúde, usando dessa interface de áreas como conteúdo e meio pedagógico. As categorias atividade e consciência são pressupostos importantes da psicologia histórico cultural que possibilitam ao professor de educação física planejar e executar suas aulas considerando as peculiaridades do desenvolvimento do aluno, tendo a cultura corporal como um dos conteúdos que promovam a (trans)formação do indivíduo para uma sociedade mais humana.

Utilização de biossurfactante no escoamento de petróleo em campo maduro
Authors: Soares Anne Karine de Souza Nascimento , Souza Roberto Rodrigues
Published: May 2016

Os biossurfactantes são compostos orgânicos que podem ser utilizados como redutores das altas tensões interfaciais entre o óleo e a água contidos em rochas reservatório, e com isso aumentar os índices de recuperação de óleo. Com objetivo de avaliar a mobilidade do petróleo em meio poroso, foram analisadas as características do meio e dos fluidos, simulando as condições reais de pressão e temperatura na produção de óleo em um poço, seguindo a metodologia apresentada por Silva (2011) para produção de biossurfactante e Curbelo (2006) para análise da recuperação do óleo. Como resultado das análises propostas para o biossurfactante em estudo, foi determinada a concentração micelar crítica (CMC), com valor de 50mg/L, apresentando estabilidade frente a elevadas temperaturas e altas concentrações salinas. O meio poroso estudado apresentou uma porosidade em torno de 39,78% e uma permeabilidade de 124,37 mD. Na análise de recuperação de petróleo os resultados foram satisfatórios, apresentando um fator de recuperação parcial de 30,66% e o fator de recuperação total de 50,47% com a injeção de biossurfactante. Conclui-se, portanto, que o Bacillus subtilis possui um grande potencial para utilização em processo MEOR.
Copeptin predicts 10-year all-cause mortality in community patients: a 10-year prospective cohort study
Authors: Odermatt Jonas , Bolliger Rebekka , Hersberger Lara , Ottiger Manuel , Christ-Crain Mirjam , Briel Matthias , Bucher Heiner C. , Mueller Beat , Schuetz Philipp
Published: May 2016

Background:

Copeptin, the C-terminal part of the arginine vasopressin (AVP) precursor peptide, is secreted in response to stress and correlates with adverse clinical outcomes in the acute-care hospital setting. There are no comprehensive data regarding its prognostic value in the community. We evaluated associations of copeptin levels with 10-year mortality in patients visiting their general practitioner (GP) for a respiratory infection included in a previous trial.

Methods:

This is a post hoc analysis including data from 359 patients included in the PARTI trial. Copeptin was measured in batch-analysis on admission and after 7 days. We calculated Cox regression models and area under the receiver operating characteristic curve (AUC) to assess an association of copeptin with mortality and adverse outcome. Follow-up data were collected by GP, patient and relative tracing through phone interviews 10 years after trial inclusion.

Results:

After a median follow-up of 10.0 years, mortality was 9.8%. Median admission copeptin levels (pmol/L) were significantly elevated in non-survivors compared to survivors (13.8, IQR 5.9–27.8; vs. 6.3 IQR 4.1–11.5; p<0.001). Admission copeptin levels were associated with 10-year all-cause mortality [age-adjusted hazard ratio 1.7 (95% CI, 1.2–2.5); p<0.001, AUC 0.68]. Results were similar for discharge copeptin levels. Copeptin also predicted adverse outcomes defined as death, pulmonary embolism and major adverse cardiac and cerebrovascular events.

Conclusions:

In a sample of community-dwelling patients visiting their GP for a respiratory infection, copeptin levels were associated with 10-year all-cause mortality. In conjunction with traditional risk factors, this marker may help to better direct preventive measures in this population.

In large systems, such as health care, reforms are underway constantly. The article presents a definition of health care reform and factors that influence its success. The factors being discussed range from knowledgeable personnel, the role of involvement of international experts and all stakeholders in the country, the importance of electoral mandate and governmental support, leadership and clear and transparent communication. The goals set need to be clear, and it is helpful to have good data and analytical support in the process. Despite all debates and experiences, it is impossible to clearly define the best approach to tackle health care reform due to a different configuration of governance structure, political will and state of the economy in a country.

Rodríguez-Rosell, D, Mora-Custodio, R, Franco-Márquez, F, Yáñez-García, JM, González-Badillo, JJ. Traditional vs. sport-specific vertical jump tests: reliability, validity, and relationship with the legs strength and sprint performance in adult and teen soccer and basketball players. J Strength Cond Res 31(1): 196–206, 2017—The vertical jump is considered an essential motor skill in many team sports. Many protocols have been used to assess vertical jump ability. However, controversy regarding test selection still exists based on the reliability and specificity of the tests. The main aim of this study was to analyze the reliability and validity of 2 standardized (countermovement jump [CMJ] and Abalakov jump [AJ]) and 2 sport-specific (run-up with 2 [2-LEGS] or 1 leg [1-LEG] take-off jump) vertical jump tests, and their usefulness as predictors of sprint and strength performance for soccer (n = 127) and basketball (n = 59) players in 3 different categories (Under-15, Under-18, and Adults). Three attempts for each of the 4 jump tests were recorded. Twenty-meter sprint time and estimated 1 repetition maximum in full squat were also evaluated. All jump tests showed high intraclass correlation coefficients (0.969–0.995) and low coefficients of variation (1.54–4.82%), although 1-LEG was the jump test with the lowest absolute and relative reliability. All selected jump tests were significantly correlated (r = 0.580–0.983). Factor analysis resulted in the extraction of one principal component, which explained 82.90–95.79% of the variance of all jump tests. The 1-LEG test showed the lowest associations with sprint and strength performance. The results of this study suggest that CMJ and AJ are the most reliable tests for the estimation of explosive force in soccer and basketball players in different age categories.

Resistance to thyroid hormone (RTH) is a syndrome of reduced tissue responsiveness to thyroid hormones. RTH is majorly caused by mutations in the thyroid hormone receptor beta (THRB) gene. Recent studies indicated a close association of THRB mutations with human cancers, but the role of THRB mutation in carcinogenesis is still unclear. Here, we report a rare case of RTH with a papillary thyroid carcinoma (PTC). A 26-year-old woman was referred to our hospital due to a thyroid tumor and hormonal abnormality. She had elevated serum thyroid hormones and non-suppressed TSH levels. Genetic analysis of THRB identified a missense mutation, P452L, leading to a diagnosis of RTH. Ultrasound-guided fine-needle aspiration biopsy of the tumor and lymph nodes enabled the cytological diagnosis of PTC with lymph node metastases. Total thyroidectomy and neck lymph nodes dissection were performed. Following surgery, thyroxine replacement (≥500 μg) was necessary to avoid the symptoms of hypothyroidism and to maintain her TSH levels within the same range as before the operation. During the follow-up, basal thyroglobulin (Tg) levels were around 6 ng/ml and TSH-stimulated Tg levels were between 12 and 20 ng/ml. Up to present, the patient has had no recurrence of PTC. This indicates that these Tg values are consistent with a biochemical incomplete response or an indeterminate response. There is no consensus regarding the management of thyroid carcinoma in patients with RTH, but aggressive treatments such as total thyroidectomy followed by radioiodine (RAI) and TSH suppression therapy are recommended.

Learning points

There are only a few cases reporting the coexistence of RTH and thyroid carcinoma. Moreover, our case would be the first case presenting one with lymph node metastases.

Recent studies indicated a close association of THRB mutations with human cancers, but the role of THRB mutation in carcinogenesis is still unclear.

When total thyroidectomy is performed in patients with RTH, a large amount of thyroxine is needed to maintain their thyroid function.

There is no consensus regarding the management of thyroid carcinoma in patient with RTH, but effective treatments such as total thyroidectomy followed by RAI and TSH suppression therapy are recommended.

Cardiac resynchronisation therapy (CRT) can profoundly improve outcome in selected patients with heart failure; however, response is difficult to predict and can be absent in up to one in three patients. There has been a substantial amount of interest in the echocardiographic assessment of left ventricular dyssynchrony, with the ultimate aim of reliably identifying patients who will respond to CRT. The measurement of myocardial deformation (strain) has conventionally been assessed using tissue Doppler imaging (TDI), which is limited by its angle dependence and ability to measure in a single plane. Two-dimensional speckle-tracking echocardiography is a technique that provides measurements of strain in three planes, by tracking patterns of ultrasound interference (‘sspeckles’s) in the myocardial wall throughout the cardiac cycle. Since its initial use over 15 years ago, it has emerged as a tool that provides more robust, reproducible and sensitive markers of dyssynchrony than TDI. This article reviews the use of two-dimensional and three-dimensional speckle-tracking echocardiography in the assessment of dyssynchrony, including the identification of echocardiographic parameters that may hold predictive potential for the response to CRT. It also reviews the application of these techniques in guiding optimal LV lead placement pre-implant,with promising results in clinical improvement post-CRT.
Прооксидантний і антиоксидантний баланс крові коней української верхової породи в динаміці фізичних навантажень

Досліджено вміст маркерів оксидаційного стресу та активність ферментів антиоксидантного захисту у крові, плазмі та суспензії еритроцитів коней української верхової породи, які використовуються у класичних видах кінного спорту. Встановлено достовірні зміни інтенсивності перекисного окиснення ліпідів еритроцитів та вмісту похідних оксидаційної модифікації білків плазми, а також активності ферментів антиоксидантного захисту крові спортивних коней у динаміці тренувань. Виявлено істотне зниження вмісту малонового діальдегіду у суспензії еритроцитів і продуктів окиснювальної модифікації білків плазми коней після фізичних навантажень, що свідчить про розвиток ефективних адаптаційних реакцій. У динаміці тренінгу спостерігалось також істотне підвищення активності ферментів антиоксидантного захисту (супероксиддисмутази та глутатіонредуктази). Кореляційний аналіз залежності між маркерами оксидаційного стресу та системи антиоксидантного захисту виявив важливу роль ферментів глутатіонової ланки, які попереджують розвиток пероксидації ліпідів і білків під час фізичних навантажень у коней української верхової породи. Таким чином, рівень маркерів оксидаційного стресу та активність ферментів антиоксидантного захисту у спортивних коней можуть бути інформативними показниками для оцінки рівня тренованості коней спортивного напряму працездатності.

Проаналізовано віковий склад, довжину та масу тіла популяцій плітки звичайної (Rutilus rutilus L.) у водоймах із різним рівнем промислового навантаження. Кременчуцьке водосховище, яке формує понад 50% річного промислового вилову R. rutilus в Україні, обрано як водойму з надмірним тиском промислу. Для порівняння взято акваторії природного заповідника «Дніпровсько-Орільський» як приклад водного об’єкта, де тиск промислу мінімізований. Віковий ряд R. rutilus на відкритому плесі водосховищ Дніпра набагато довший, ніж у його придаткових річкових системах. Розмірно-вагові показники вікових груп R. rutilus 6+ – 10+ у водоймі з інтенсивним антропогенним навантаженням статистично достовірно нижчі, ніж в особин на природоохоронних акваторіях. Це можна пояснити наслідком селективної дії традиційного промислу ставними сітками, якими вилучаються особини з більшими темпами росту. На спрямовану елімінацію швидкоростучих особин вказали криві приростів і час настання кульмінації приросту іхтіомаси. Таким чином, потужне промислове навантаження на популяції R. rutilus і активне їх вилучення ставними сітками спричиняє накопичення тугорослих особин.

Надано оцінку стійкості популяцій земноводних на основі даних динаміки чисельності. Зроблено спробу оцінити напрям динамічних змін популяцій земноводних. Визначено швидкість відхилення системи від стаціонарного стану внаслідок впливу можливих чинників навколишнього середовища за допомогою такого поняття як реактивність, ступінь реактивності та еластичності системи із застосуванням їх індексів. Установлено, що стаціонарний стан угруповань земноводних заплави р. Самара стійкий. Характерною ознакою є еластичність системи. Підтверджено еластичність системи особин Bufo bufo (Linnaeus, 1758). Визначено Pelobates fuscus (Laurenti, 1768) як фактор стійкості екосистеми у кількісному відношенні. Встановлено залежність динамічних показників популяцій від їх чисельності за допомогою рівняння регресії. Динаміка угруповання залежить від дії можливих предикторів, у відповідь на яких популяція B. bufo не змінюється. Стаціонарний стан угруповання нестабільний відносно динамічної матриці, яка описує поведінку угруповання в околиці першого стаціонарного стану. Другий стаціонарний стан стабільний, але система повертається у нього протягом хвилеподібної динаміки. На основі проведених досліджень встановлено, що чисельність угруповань земноводних залишається стійкою, системи поводяться по-різному, динаміка їх повернення до стаціонарного стану еластична або реактивна.
