Atividade física para gestantes: estudo com praticantes e não praticantes
Authors: Vieira Costa Alisson , Silva Dias Marcela Fabiani 
Published: May 2024

A prática de atividade física por gestantes é de fundamental, uma vez que pode melhorar o condicionamento físico e diminuir alguns dos sintomas desagradáveis que a mulher, nesta fase, sente. Este estudo torna-se importante aos professores de educaçao física, já que oferece um conhecimento específico acerca do tema, no sentido de ampliar o campo de atuação profissional. Nos procedimentos metodológicos comparou-e a qualidade de vida de gestantes praticantes e não praticantes de atividade física. A amostra foi composta por 10 gestantes, sendo 5 praticantes de atividades físicas e 5 não praticantes. Os instrumentos utilizados para a coleta de dados constituíram-se de dois questionários-diagnósticos, sendo que um foi direcionado para praticantes de atividade física e o outro para as não praticantes. No grupo das não praticantes, a maioria das entrevistadas relatou que não praticavam atividade física por “falta de tempo”. Os maiores desconfortos que as gestantes sentem são o sono e a ansiedade. No grupo das praticantes, a maioria fazia hidroginástica. As melhoras mais significativas neste grupo foi a dor nas costas e a indisposição. Com base no exposto e de acordo com a literatura utilizada nesta investigação é possível afirmar que a prática de atividade física para gestantes é uma ferramenta indispensável para a melhoria da qualidade de vida das mesmas, em oposição às não praticantes.

В последние десятилетия накапливается все больше данных о механизмах обновления и регенерации тканей, которые были бы невозможны без участия стволовых клеток. Доказано, что данные процессы во многих тканях осуществляются за счет тканеспецифичных стволовых клеток (ТСК), однако их получение, культивация и введение с терапевтической целью крайне затруднительны. Наряду с этим наибольший интерес представляют мезенхимальные стволовые клетки (МСК), которые, благодаря возможности их выделения, экспансии и мультипотентности, являются многообещающим терапевтическим агентом, уже доказавшим свою клиническую эффективность при различных нозологиях, в том числе в вопросах тканевой инженерии. Одной из особенностей МСК, введенных системно, является способность находить нишу в пораженной ткани и оставаться в ней, оказывая существенное влияние на воспаление, процессы ремоделирования ткани и ее регенеративный потенциал. Однако механизмы дифференцировки и миграции МСК, а также факторы, влияющие на эти процессы, раскрыты не полностью. В данном обзоре обобщены современные данные о механизмах миграции МСК и возможных путях ее улучшения.
In recent decades a lot of data have been accumulated on the mechanisms of tissue renewal and regeneration, which would be impossible without the participation of stem cells. It has been proven that these processes in many tissues are carried out by tissue-specific stem cells (TSCs), but their production, cultivation and administration for therapeutic purposes are extremely difficult. Along with this, mesenchymal stem cells (MSCs) are a promising therapeutic agent that has already proven its clinical effectiveness in various diseases and in tissue engineering. One of the features of MSCs introduced systemically is the ability to find a niche in the affected tissue and remain there, having a significant impact on inflammation, tissue remodeling processes and its regenerative potential. However, the mechanisms of differentiation and migration of MSCs, as well as the factors influencing these processes, are not fully disclosed. This review makes an attempt to summarize the accumulated data on the mechanisms of MSC migration and possible ways to improve it.

ABSTRACTRecognition of the molecular basis of gastrointestinal stromal tumors has paved the way for significant breakthroughs in the diagnosis and treatment of this disease as well as positioned gastrointestinal stromal tumors as a framework for the concept of precision oncology in solid tumors. The incorporation of novel targeted agents for molecularly defined subgroups has led to significant improvements in treatment outcomes; however, the characterization of heterogeneous KIT or PDGFRA mutations and the emergence of resistance mechanisms highlight the need for a broader use of comprehensive molecular profiling and emphasize the importance of molecularly driven adaptive treatment strategies. Such a molecular background is critical for developing personalized and effective interventions and optimizing outcomes. The present review summarizes key studies that provide the basis for standard-of-care management options as well as provides molecular insights into the management of gastrointestinal stromal tumors, with an emphasis on recent advances.
Dynamism and participant identification in the discursive construction of the American nation
Authors: Guerra Lyons Jesús David , De la Rosa Yacomelo Johan , Villanueva Niebles Elkin 
Published: May 2024

This article analyzes the linguistic choices used in political discourse to represent social actors and their role in the construction of national storylines. We focus on Donald Trump’s and Joseph Biden’s inaugural speeches as a critical exploratory context. The analytical approach involves contrasting their choices for assigning dynamism to socialactors through transitivity roles and for identifying participants through direct, indirect, and pronominal strategies. Our findings show that Trump assigns Actor + Goal roles that construe citizens as agents impinging on material reality, while Biden assigns them Actor – Goal roles that represent citizens as participants in happenings. Trump’s identification of participants shows a higher proportion of indirect strategies linked with possessivequalification, whereas Biden stands out for his frequent use of the singular first person. The findings suggest connections between the strategies identified and the construction of national identities and storylines, both permeated by political leaders’ ideological orientations.

Gang involvement: psychological and behavioral characteristics of gang members, peripheral youth, and nongang Youth
Authors: Alleyne Emma , Wood Jane L. 
Published: August 2010

AbstractResearch has noted the existence of a loose and dynamic gang structure. However, the psychological processes that underpin gang membership have only begun to be addressed. This study examined gang members, peripheral youth, and nongang youth across measures of criminal activity, the importance they attach to status, their levels of moral disengagement, their perceptions of out‐group threat, and their attitudes toward authority. Of the 798 high school students who participated in this study, 59 were identified as gang members, 75 as peripheral youth, and 664 as nongang youth. Gang members and peripheral youth were more delinquent than nongang youth overall; however, gang members committed more minor offenses than nongang youth and peripheral youth committed more violent offenses than nongang youth. Gang members were more anti‐authority than nongang youth, and both gang and peripheral youth valued social status more than nongang youth. Gang members were also more likely to blame their victims for their actions and use euphemisms to sanitize their behavior than nongang youth, whereas peripheral youth were more likely than nongang youth to displace responsibility onto their superiors. These findings are discussed as they highlight the importance of examining individual differences in the cognitive processes that relate to gang involvement. Aggr.

Fabrication and Characterization of Superhydrophobic Surfaces with Dynamic Stability
Authors: Yao Xi , Xu Liang , Jiang Lei 
Published: August 2010

AbstractSuperhydrophobic surfaces of dynamic stability are crucial for applications in water‐repellent materials. In this work, a hierarchical structure composed of a dendritic microporous surface with nanostructured porosity is demonstrated that shows robust superhydrophobicity with dynamic stability. The hierarchical structures are obtained on both copper foils and wires by a dynamic gas‐bubble template‐assisted electrochemical deposition method. The substrates can then be modified with alkyl thiols to obtain the surface superhydrophobicity. A new kind of testing, mechanical monitor‐assisted continuous water surface strokes, is developed to reveal the dynamic stability of the as‐prepared superhydrophobic copper wires. The as‐prepared superhydrophobic copper wires can exert a high propulsive force, and particularly, show little adhesive force in the process of continuous strokes on the water surface, exhibiting robust superhydrophobicity with dynamic stability. The approach allows a strategy for the fabrication of superhydrophobic surfaces with dynamic stability, and suggests a new method to evaluate the dynamic stability of superhydrophobic surfaces.
Tunable Dielectric Function in Electric‐Responsive Glass with Tree‐Like Percolating Pathways of Chargeable Conductive Nanoparticles
Authors: Paleari Alberto , Brovelli Sergio , Lorenzi Roberto , Giussani Marco , Lauria Alessandro , Mochenova Natalia , Chiodini Norberto 
Published: August 2010

AbstractThe design of nanostructured materials with specific physical properties is generally pursued by tuning nanoparticle size, concentration, or surface passivation. An important step forward is to realize “active” systems where nanoparticles are vehicles for controlling, in situ, some specific, tuneable features of a responsive functional material. In this perspective, this work focuses on the rational design of a nanostructured glass with electrically tuneable dielectric function obtained by injection and accumulation of charge on embedded conductive nanocrystals. This enables electrically controlled switching of semiconducting nanophases to charged polarisable states to be achieved, which could lead to smart, field‐enhancement applications in nanophotonics and plasmonics. Here, it is shown that such response switching can be obtained if a percolating charge‐transport mechanism is activated through a disordered tree‐like network, as is demonstrated to be possible in SiO2 films where suitable dispersions of SnO2 nanocrystals, with conductive interfaces, are obtained as a result of a new synthesis strategy.
The 2D:4D digit ratio is not a useful marker for prenatal famine exposure: Evidence from the Dutch hunger winter families study
Authors: Stein Aryeh D. , Kahn Henry S. , Lumey L.H. 
Published: August 2010

AbstractObjectives: Digit lengths, and in particular the ratio of the 2nd (2D) to 4th (4D) digit (2D:4D), are stable in adulthood and have been linked to characteristics thought to have developmental origins, but little research has focused on early life determinants of these measures. We examined whether exposure to acute famine during specific periods of gestation was associated with 2D, 4D or the 2D:4D ratio.Methods: We studied men and women (1) born in one of three hospitals in western Netherlands whose mothers were exposed to a limited period of famine immediately prior to or during the pregnancy (n = 337); (2) born in the same hospitals to mothers not exposed to famine during the pregnancy (n = 271) or same‐sex siblings of individuals in Groups 1 and 2 (n = 295). We measured 2D and 4D on both hands using calipers and computed the 2D:4D ratio.Results: Mean 2D and 4D lengths were 73.5 (SD 5.1) and 75.0 (5.4) mm, respectively. The 2D:4D ratio was 0.981 (SD 0.030). Both 2D and 4D were associated with male gender and height (all P < 0.001), and weakly with BMI. The 2D:4D ratio was 0.0070 (95% confidence interval 0.0017, 0.0123) lower among males as compared with females, and was not significantly associated with height (0.0002 per cm; 95% −0.0001, 0.0005). The 2D:4D ratio was not significantly associated with exposure to famine, overall (−0.0010, 95% CI 0.0030, 0.0050) or within any period of gestation.Conclusions: The 2D:4D ratio is not significantly affected by prenatal exposure to famine and therefore is not a useful marker for generalized prenatal undernutrition.

A model for assessing occupational exposure to extremely low‐frequency magnetic fields in fabrication rooms in the semiconductor health study
Authors: Abdollahzadeh Sassan , Katharine S. Hammond , Schenker Marc B. 
Published: August 2010

AbstractA model was created to assess occupational exposure to extremely low‐frequency MAgnetic fields (ELF‐MF) among semiconductor fabrication‐room (fab) workers. This model was based on the assumption that each subject's exposure arose from being near identifiable ELF‐MF sources or being in areas with high ELF‐MF levels. To assess ELF‐MF exposures, the model superimposed subjects' time‐activity patterns (patterns of how and where they spent their time) with measurements of MAgnetic‐field levels from devices and work areas. This model, which was validated by personal dosimetry on 192 persons in three fabs, predicted actual time‐weighted average exposures with a correlation coefficient of 0.62. The inability of the model to predict individual exposures more accurately was attributed to unforeseen sources of elevated ELF‐MF (transformers, distribution panels, sources in adjacent rooms) or to errors in subjects' judgments of time spent near devices. These unpredictable errors are intrinsic to the method used to Estimate exposure.
