Deslocamentos das cabeças da mandíbula entre as posições de máxima intercuspidação habitual (MIH) e de relação cêntrica (RC) são ocorrências encontradas nas mordidas cruzadas posteriores unilaterais em crianças. Desta forma os mesmos foram estudados em 18 crianças com a referida maloclusão, com media de idade de 7,2 anos para o gênero feminino e 8,4 anos para o gênero masculino. A correção dessa foi efetuada com o aparelho de recobrimento oclusal de acrílico associado ao parafuso hyrax, ajustado à oclusão do paciente de modo a promover contatos bilaterais simultâneos e múltiplos, resultando em algum grau de desprogramação. Os deslocamentos foram medidos nos três planos do espaço por meio do indicador de posição condilar (IPC), antes e após a expansão rápida da maxila com o referido aparelho. Pode-se observar que os deslocamentos condilares entre as posições de RC e MIH, nos planos vertical e horizontal, no tempo pré-expansão, mostraram-se significativamente maiores que os encontrados no tempo pós-expansão, demonstrando assim, diminuição dos mesmos após a correção da maloclusão. No plano transversal não houve diferenças entre os tempos pré e pós-expansão. A comparação entre os lados direito e esquerdo dos deslocamentos estudados no tempo pré-expansão...

A Escola Politécnica da Universidade de São Paulo (EPUSP, Brasil) e o Instituto Dante Pazzanese de Cardiologia (IDPC, Brasil) estão desenvolvendo conjuntamente um Dispositivo de Assistência Ventricular (DAV) baseado numa bomba de vazão mista e utilizando mancais magnéticos que objetivem substituir os mancais convencionais, pois o uso de mancal magnético neste dispositivo minimiza a hemólise e melhora o tempo de vida do DAV, isso em razão da ausência e contato de um mancal com a crase sanguínea o que, por fim, aumenta a vida útil do dispositivo. O mancal magnético utilizado para o DAV será o mancal do tipo híbrido. Este tipo de mancal combina ímãs permanentes com eletroímãs para realizar a levitação do rotor com controle apenas na direção axial do rotor. Na configuração original desse mancal magnético, um sensor indutivo detecta a posição axial do rotor. Esta posição é enviada a um controlador do tipo PID e processada, amplificada e enviada aos atuadores eletromagnéticos. A corrente enviada aos eletroímãs é controlada de maneira a manter o rotor sempre em uma posição axial fixa. No entanto, essa configuração exige o uso de um atuador eletromagnético contendo um furo para a instalação do sensor indutivo...

AIMS—To investigate and compare heart rate variability (HRV) and responses of heart rate and arousal to head-up tilting in infants sleeping prone and supine.
METHODS—Thirty seven healthy infants aged 2-4 months were studied. HRV was measured for 500 beats while they were in a horizontal position. Subjects were then tilted 60° head-up, and heart rate recorded over 1 minute and arousal responses observed. Data were collected during both quiet and active sleep for both prone and supine sleep positions.
RESULTS—HRV, as assessed by the point dispersion of Poincaré plots, was significantly reduced in the prone position for both sleep states. Sleep position did not influence the changes in heart rate seen during a head-up tilt. Full awakening to the tilt was common in active sleep but significantly less so in the prone position (15% of prone tests vs 54% supine). Full awakening to the tilt rarely occurred during quiet sleep in either sleep position.
CONCLUSION—This study provides some evidence that blunted arousal responses and/or altered autonomic function are a feature of the prone sleeping position. Decreased HRV may be a sign of autonomic impairment. It is seen in many disease states and in infants who later die of sudden infant death syndrome (SIDS).

In his review of my book, Better never to have been, Len Doyal suggests, contrary to my view, that rational beings in the original position might prefer coming into existence to the alternative of never existing, if their lives were to include enough good and not too much bad. I argue, in response, that Professor Doyal fails to make his case.

Despite the increasing popularity of blood pressure (BP) wrist monitors for self-BP measurement at home, device validation and the effect of arm position remains an issue. This study focused on the validation of the Omron HEM-609 wrist BP device, including an evaluation of the impact of arm position and pulse pressure on BP measurement validation. Fifty patients at high risk for cardiovascular disease were selected (age 65 ± 10 years). Each patient had two measurements with a mercury sphygmomanometer and three measurements with the wrist BP device (wrist at the heart level while the horizontal arm supported [HORIZONTAL], hand supported on the opposite shoulder [SHOULDER], and elbow placed on a desk [DESK]), in random order. The achieved systolic BP (SBP) and diastolic BP (DBP) wrist-cuff readings were compared to the mercury device and the frequencies of the readings within 5, 10, and 15 mmHg of the gold standard were computed and compared with the British Hypertension Society (BHS) and Association for the Advancement of Medical Instrumentation (AAMI) protocols. The results showed while SBP readings with HORIZONTAL and SHOULDER positions were significantly different from the mercury device (mean difference = 7.1 and 13.3 mmHg, respectively; P < 0.05)...

Aedes aegypti and Aedes albopictus are competent natural and laboratory vectors for numerous arthropod-borne viruses (arboviruses), many of which pose global public health concerns. Efficiently imbibing a blood meal from an artificial membrane feeder, Ae. aegypti is an easy feeder: ∼96% success. Alternatively, Ae. albopictus is known to be a difficult feeder imbibing poorly: ∼20% success. Adult female mosquitoes were grouped in cohorts of 50, proffered a bovine blood meal, and challenged with experimental variables, and feeding success was documented. Controls included Ae. aegypti and the artificial glass membrane feeder: topside presentation (upside-down feeding position only). Variables included lambskin versus bovine collagen sausage membranes, presence or absence of gentle motion, filial generations, and large or small blood packets positioned differently: horizontal presentation (right side-up or nose-up feeding position) and vertical presentation (nose-up feeding position only). Both species preferred sausage casings, and ultrastructural analysis revealed that sausage casings had a textured gripping surface not observed on lambskin membranes. Neither filial generations nor gentle motion improved feeding; however, a 32%–46% increase in blood feeding was observed when Ae. albopictus fed on large horizontal and large or small vertical blood packets. Upside-down feeding of Ae. albopictus with a blood suspension of Sindbis virus heat resistant (SVHR) and the original isolate (AR339) resulted in virus dissemination of 10% and 50%...

[Purpose] This study investigated the effect of functional electrical stimulation (FES) of stroke patients in a sitting position on balance and activities of daily living. [Methods] FES was applied to stroke patients (six male, three female) while in a sitting and supine position. FES was applied six times for 30 minutes each for a total of six weeks. [Results] The timed up and go (TUG) values at weeks 2, 4, and 6 after FES treatment in a sitting position were noticeably decreased in a time-dependent manner, compared with controls. In the sitting, the functional reach test (FRT) values were significantly increased in a time-dependent manner. The same values in the supine position weakly showed a similar pattern to those in the sitting position. Furthermore, the functional independent measurement (FIM) values in the sitting position were markedly increased in a time-dependent manner. In the sitting position, the intensity of FES was markedly decreased in a time-dependent manner. The same values in the supine position weakly showed a similar pattern to those in the sitting position. [Conclusion] These results suggest that the conditions of stroke patients in both the sitting and supine positions after FES treatment were improved and that FES had a greater effect in the sitting position.

Immobilized skeletal muscle fixed in a shortened position displays disuse atrophy, whereas when fixed in a stretched position it does not (Goldspink, D. F. (1977) J Physiol 264, 267–282). Although significant advances have been made in our understanding of mechanisms involved in development of atrophy in muscle fixed in a shortened position, little is known about why mass is maintained when muscle is immobilized in a stretched position. In the present study, we hypothesized that skeletal muscle immobilized in a stretched position would be protected from gene expression changes known to be associated with disuse atrophy. To test the hypothesis, male Sprague‐Dawley rats were anesthetized using isoflurane and subjected to unilateral hindlimb immobilization for 3 days with the soleus fixed in either a shortened or stretched position. All comparisons were made to the contralateral nonimmobilized muscle. Soleus immobilized in a shortened position exhibited disuse atrophy, attenuated rates of protein synthesis, attenuated mTORC1 signaling, and induced expression of genes for REDD1, REDD2, MAFbx, and MuRF1. In contrast, immobilization of the soleus in a stretched position prevented these changes as it exhibited no difference in muscle mass...

Objectives: The main objective of this study was to observe the behavior of the fetal head position during labor, when starting from occiput anterior or posterior position and also to determine their importance in labor management (if the starting fetal head position can be a strong argument in favour of vaginal or cesarean delivery). Methods:187 patients in labor were included in this study, with gestational age over 37 weeks and estimated fetal weight over 2500 g, singleton pregnancy, cephalic presentation, empty urinary bladder. For these patients the ultrasound assessed parameters were: fetal head position at the beginning of labour and fetal head rotation during labour. Results: 89,18 percent of the patients starting from OTP (occiput transverse or posterior position) had a vaginal birth after an anterior rotation of the fetal head, and only 10,82 % presented persitent occiput posterior requiring cesarean section for delivery. Furthermore, considering only initial occiput posterior position, we observed an increased rate for cesarean section delivery (22,72%) by persistence of this position during labour. None of the patients starting with an anterior fetal head position rotated posteriorly. Conclusions: vaginal delivery in occiput anterior position was the most common result in both OTP and OP fetal head initial position. The main reason for cesarean delivery was persistent OP position. Patients with occiput posterior position were subsequent only to an initial posterior/transverse position.

[Purpose] Knee joint proprioception combines sensory input from a variety of afferent receptors that encompasses the sensations of joint position and motion. Poor proprioception is one of the risk factors of anterior cruciate ligament injury. Most studies have favored testing knee joint position sense in the sagittal plane and non-weight-bearing position. One of the most common mechanisms of noncontact anterior cruciate ligament injury is dynamic knee valgus. No study has measured joint position sense in a manner relevant to the mechanism of injury. Therefore, the aim of this study was to measure knee joint position sense in the noncontact anterior cruciate ligament injury risk position and normal condition. [Subjects and Methods] Thirty healthy male athletes participated in the study. Joint position sense was evaluated by active reproduction of the anterior cruciate ligament injury risk position and normal condition. The dominant knees of subjects were tested. [Results] The results showed less accurate knee joint position sense in the noncontact anterior cruciate ligament injury risk position rather than the normal condition. [Conclusion] The poorer joint position sense in non-contact anterior cruciate ligament injury risk position compared with the normal condition may contribute to the increased incidence of anterior cruciate ligament injury.

[Purpose] This study investigated the selective activation of the gluteus maximus during a prone hip extension with knee flexion exercise, with the hip joint in different positions. [Subjects] The subjects were 21 healthy, male volunteers. [Methods] Activities of the right gluteus maximus, right hamstrings, bilateral lumbar erector spinae, and bilateral lumbar multifidus were measured using surface electromyography during a prone hip extension with knee flexion exercise. Measurements were made with the hip joint in each of 3 positions: (1) a neutral hip joint position, (2) an abduction hip joint position, and (3) an abduction with external rotation hip joint position. [Results] Gluteus maximus activity was significantly higher when the hip was in the abduction with external rotation hip joint position than when it was in the neutral hip joint and abduction hip joint positions. Gluteus maximus activity was also significantly higher in the abduction hip joint position than in the neutral hip joint position. Hamstring activity was significantly lower when the hip was in the abduction with external rotation hip joint position than when it was in the neutral hip joint and abduction hip joint positions. [Conclusion] Abduction and external rotation of the hip during prone hip extension with knee flexion exercise selectively activates the gluteus maximus.

[Purpose] The purpose of the present study was to investigate the limb position at which the maximum toe-grip strength could be exerted as well as measurement reproducibility. [Subjects] Twenty healthy young women were selected. [Methods] We measured toe-grip strength under three conditions: 90° hip and knee flexion while sitting, 90° hip flexion and knee extension while sitting, and a standing position. [Results] We found that toe-grip strength was significantly lower in the 90° hip flexion and knee extension sitting position than in the 90° hip and knee flexion sitting position and standing position. Moreover, the 90° hip and knee flexion sitting position produced the best intraclass correlation coefficient (r = 0.813). [Conclusion] The results suggest that 90° hip and knee flexion while sitting is the most suitable limb position for measuring toe-grip strength, as this position allows maximum strength to be exerted and allows measurements to be repeated.

Ce mémoire examine le rôle de la diversité dans une conception de la justice. Je débute en considérant l’abstraction de la différence impliquée dans le raisonnement utilisé pour arriver à une conception de la justice. Par la suite j’évalue le rôle des différences des groupes sociaux dans l’application des principes de justice, en considérant si la justice exige des droits individuels ou si les groupes peuvent revendiquer des droits différenciés. Ce mémoire utilise la position originale de John Rawls pour évaluer la première question, et sa conception de la personne et des groupes sociaux pour examiner la deuxième. Je soutiens que nous pouvons et devrions utiliser l’abstraction de la position originale, tant que nous sommes conscients de ses limites. Bien que sa conception politique de la personne soit également utile pour la défense des droits individuels, sa conception du groupe social n’est pas appropriée pour les groupes culturels ou historiquement opprimés, car il repose trop lourdement sur la notion d’association volontaire. J’analyse l’argument de Will Kymlicka concernant les droits minoritaires et j’enrichis la théorie de Rawls en ajoutant l’inégalité entre groupes. Je termine en examinant les problèmes concernant les minorités à l’intérieur des groupes minoritaires et conclue que les droits minoritaires ne sont justifiées que lorsqu’ils sont compatibles avec les droits individuels...

En este trabajo examino la teoría rawlsiana del derecho de gentes. Defiendo que el tratamiento de John Rawls de las relaciones entre Estados constituye una auténtica novedad en los planteamientos de este autor, ya que su principal objeto de estudio fue, desde sus primeros artículos, el contenido de la concepción de la justicia para las sociedades democráticas. Pero su propuesta se enfrenta a una serie de dificultades, que hacen imposible su intención de articular el derecho de gentes en una posición original análoga a la del nivel doméstico de las sociedades democráticas. Uno de esos obstáculos lo constituye su negativa de articular un principio de diferencia global, que, sin embargo, como argumentaré, podría ser derivado de su misma concepción del derecho de gentes.   In this paper I examine Rawls’s theory of the jus gentium, or law of peoples. I argue that his treatment of the relation between States is new in John Rawls, because from his earlier papers onward his main subject had been how democratic societies conceive justice. But Rawls’s proposal has some difficulties that make it impossible to fulfil its intention to articulate the law of peoples in one original position analogous to the original position of democratic societies at the domestic level. One of these obstacles is the proposal’s refusal to articulate one global difference principle...

There are many reports on position-related complications in neurosurgical literature but so far, continuous quantification of the patient’s position during the surgery has not been reported. This study aims to explore the utility of a new surgical table system and its software in displaying the patient’s body positions during surgery on real-time basis. More than 200 neurosurgical cases were monitored for their positions intra-operatively. The position was digitally recorded and could be seen by all the members in the operating team. It also displayed the three-dimensional relationship between the head and the heart positions. No position-related complications were observed during the study. The system was able to serve as an excellent indicator for monitoring the patient’s position. The recordings were analyzed and even used to reproduce or improve the position in the subsequent operations. The novel technique of monitoring the position of the head and the heart of the patients and the operating table planes are considered to be useful during delicate neurosurgical procedures thereby, preventing inadvertent procedural errors. This can be used to quantify various surgical positions in the future and define safety measures accordingly.

Errors when judging an offside position in football are very frequent. In the last years, several scientific papers have tried to explain the causes for human errors. When a referee or an assistant referee misjudges an offside position, it is thought to be caused by a human error. A human error means to carry out incorrectly an action we are physiologically qualified for. The hypothesis to be studied in this paper is if when judging an offside position it is possible to attribute errors to humans or to the fact that human physiology and the technical media are not capable of detecting an offside position. The offside rule has to be applied in real time, in zero milliseconds, in the precise moment when the ball is being passed, never 1 millisecond or even 1 millionth of a second later. This paper shows that the human being and the technological media are both physically and technically incapable of detecting an offside position in real time, in zero milliseconds. The results of this study show that when the ball is passed, the human eye and brain and the technological media need some time to locate the at least four players who intervene in an offside position. When those players are located, time has passed and they are never in the original position...

The impact and relevance of economic theory to the development of “A Theory of Justice” are often left aside in the immense literature regarding the works of John Rawls. And yet, understanding the elements of political economy in Rawls’work is fundamental for the comprehension of why Rawls will abandons a utilitarian approach to political philosophy and, consequentially, for our understanding of the main issues that motivate the notion of Justice as Fairness.  This article has two mains goals: First, to describe the influence of John Stuart Mill, Kenneth Arrow and Vilfredo Pareto in the methodological turn found in the idea of the Original Position; and second, to describe the historical elements that are presupposed for the conceivability of Rawls’ ideals. I conclude the present paper with some remarks suggesting a historicist and phenomenological complement to the ideal descriptions found in political liberalism as understood by Rawls.; O impacto e a relevância da teoria econômica para o desenvolvimento de A Theory of Justice são, frequentemente, deixados de lado na imensa literatura a respeito das obras de John Rawls.

The aim of the present work is to compare the procedure followed in The Law of Peoples with the one followed in A Theory of Justice e Political Liberalism. I will try to show that, contrary to what Rawls claims, there are important differences between these two procedures, which originate in the conception of the basic structure, defined as the subject to which the principles of justice are applied. The differences in the concept of basic structure have important consequences on how the device of the original position is used at the international level. If Rawls had transferred to the international level the same conceptions of basic structure and original position used at the domestic case, the result would be a conception of international justice different from that which is adopted in The Law of Peoples.

Dworkin claimed that hypothetical agreements are not binding and, thus, that the argument from the Original Position in Rawls’ A Theory of Justice does not justify or ground the principles of justice. I argue that the Original Position is neither foundational nor in need of a “deep theory”, as claims Dworkin; it is only a means of clarification, a sort of “perspicuous representation” of our judgments concerning justice. I also argue that the natural duty of justice works as a non-hypothetical justification for why the principles are binding. This because the natural duty of justice does not depend on agreements to hold and, as such, makes any principle of justice binding.
