Purpose: This study evaluated the effect of lung volume at the catch position to force and power outputs during single maximal effort strokes in rowing. Responses were compared when the participants were ‘fresh’ and following specific inspiratory muscle fatigue (IMF). In addition, a single subject pilot study was performed to characterise the changes in intra-thoracic (ITP), intra-abdominal (IAP) and trans-diaphragmatic (Pdi) pressures during a 30 second maximal effort piece on a rowing ergometer. Methods: Nine male rowers of international standard participated in the research. Static force, as well as the power produced during a single stroke were assessed at residual volume (RV), 25%TLC, 50%TLC, 75%TLC, total lung capacity (TLC), and a self-selected lung volume (S-S). Lung volumes were derived from maximal flow-volume loops (MFVLs) and achieved using online real-time feedback. Inspiratory muscle fatigue (IMF) was induced by breathing against an inspiratory load equivalent to 80% baseline maximal inspiratory pressure (MIP), at a breathing frequency (fB) of 15 breaths per minute, and a duty cycle of 0.6. Expiration was unimpeded. The single subject pilot study was undertaken using balloon catheters to measure ITP, IAP, and Pdi during a 30 second maximal effort free-rating piece on the ergometer. Results: There was no significant effect of lung volume upon either force or power production. The RMF protocol induced a significant reduction in MIP (159.9 ± 70.8 vs. 106.8 ± 58.7 cmH2O; p = 0.000), but not maximal expiratory pressure (MEP; 159.9 ± 79.2 vs. 166.6 ± 53.0 cmH2O; p = 0.376). RMF induced a significant reduction in force output with increasing lung volume, across all lung volumes (mean force 1313.4 ± 31.9 vs. 1209.6 ± 45.0N; p < 0.008), but not power (mean power 598.6 ± 31.9 vs. 592.7 ± 45.0W; p > 0.05). Self-selected lung volumes were consistent across all tests for force and power (mean 38.1 ± 6.9% [Force] vs. 28.2 ± 0.6% [Power]; p > 0.017). The pilot study indicated that internal pressures fluctuate markedly during maximal effort rowing (pressure, [max, min, average] cmH2O; IAP [144.69, 7.46, 73.59], ITP [75, -22.65, 15.34], Pdi [111.84, 7.09, 58.83]), suggesting that the trunk muscles play an active role in power production during rowing. Conclusion: The present study suggests that there is no significant effect of lung volume on force or power when athletes are in a fresh condition. However, a decrement in force production is present with inspiratory muscle fatigue. Combined with evidence of high internal pressures during maximal effort rowing, these data may indicate a role for the inspiratory muscles in force production during rowing.

Aging is an intrinsic process that is independent of obvious disease. In contrast to normal aging, age-related diseases are conditions that typically manifest at advanced ages, are associated with explicit pathology and cause disability and premature death. We used Drosophila as a model to investigate the molecular-genetic mechanisms associated with aging and age-related disease. Age-related locomotor impairment (ARLI) is a serious condition for the elderly and greatly impacts their quality of life. Toward identifying genes and mechanisms that influence ARLI, we performed a forward genetic screen using Drosophila mutants. This screen identified a loss of function mutant in PDK1, a component of the insulin signaling pathway. Additional loss of function mutants in the insulin signaling pathway genes PI3K Dp110, and AKT also delayed ARLI. These results suggest a role for insulin signaling in ARLI. Wolfram Syndrome (WFS) is a progressive neurodegenerative disease that is caused by mutations in the genes WFS1 and CISD2. The function of CISD2, the most recently identified gene has not been fully resolved. We used RNAi to knockdown wfs2, the fly ortholog of CISD2 to identify genes and pathways associated with wfs2 that will provide insight into the normal function of this gene. Through a targeted genetic screen in the Drosophila eye we identified that wfs2 interacts with two lysosomal storage disease genes PPT1 and CLN3. These results suggest that WFS and lysosomal storage diseases may be influenced by common molecular-genetic mechanisms. Furthermore, wfs2 may play a role in the neurodegenerative pathways associated with lysosomal storage disease. Oxidative stress is associated with aging and age-related disease. To identify genes that can protect against endogenous oxidative stress we performed a candidate suppressor screen. This screen revealed that expression of wild-type Ataxin-3 suppressed the short lifespan of Sod2 knockdown flies. The ubiquitin associated function of Ataxin-3 was determined to be important for this suppression. Interestingly, Ataxin-3 expression also extended the short lifespan due to knockdown of thioredoxin reductase in muscle. These results suggest that Ataxin-3 expression may play a protective role against enhanced endogenous oxidative stress due to reduced function of a number of antioxidant enzymes.

Methamphetamine is a psychomotor stimulant that produces hyperactivity and euphoria and can lead to drug-seeking and abuse. An estimate from 2005 put the cost of methamphetamine abuse to society at an estimated 23.4 billion dollars. One of methamphetamine's effects is activation of glial cells and associated neuroinflammatory activity in the periphery and CNS. Glia are responsible for maintaining calcium homeostasis, neuroplasticity, immune activity, and cell signaling. Activation of glia and neuroinflammation are becoming recognized as links in drug abuse-related behavior. The goal of the present work was to assess the ability of ibudilast, AV1013, and minocycline, three glial cell modulating compounds, to attenuate responding in rodent procedures that model different aspects of methamphetamine abuse-related behavior. First, Ibudilast (1.8, 7.5, 13 mg/kg) and AV1013 (10, 30, 56 mg/kg) were examined for their effects on methamphetamine-induced (3 mg/kg) locomotor activity and sensitization in mice, the latter thought to involve neurocircuitry common with drug relapse. Ibudilast and AV1013 dose-dependently attenuated methamphetamine-induced locomotor activity and its sensitization. Second, ibudilast (1, 7.5, 10 mg/kg), AV1013 (1, 10, 30 mg/kg), and minocycline (10, 30, 60 mg/kg) were examined for their effects on methamphetamine self-administration (0.001, 0.03, and 0.1 mg/kg/inf) in rats. All three compounds significantly reduced methamphetamine (0.03 mg/kg/inf) self-administration. Results suggested baseline self-administration rate as a possible determinant of these effects; however, follow-up tests with ibudilast while controlling for baseline response rate dismissed this possibility. Additional follow-up tests identified whether the attenuation of operant response rates was specific to methamphetamine-maintained behavior. Using a behavioral economic approach, all three test compounds were determined to also affect non-nutritive banana pellet-maintained responding when the baseline strengths maintained by methamphetamine and banana pellet delivery were matched. Finally, ibudilast was evaluated for its effects on methamphetamine discrimination in rats, a procedure thought to model clinical subjective effects. Ibudilast (1, 7.5, 10 mg/kg) did not significantly modify methamphetamine’s discriminative stimulus effects when trained at either 1 or 0.56 mg/kg. These results support the hypothesis that attenuation of glial cell activity and neuroinflammation may be linked to some abuse-related behaviors of methamphetamine, reinforcing their examination as novel targets for treating methamphetamine abuse.

There is a growing consensus, based on several converging lines of evidence, which suggests schizophrenia is the product of a developmental insult occurring in the late 2 nd or early 3 rd trimester. Additionally, it has been observed that adults who abuse the noncompetitive NMDA antagonist PCP present with symptoms that mimic schizophrenia, such as hallucinations, formal thought disorder, delusions, unstable or flattened affect, social withdrawal, and impaired cognition. Thus, several labs have attempted to use early postnatal PCP administration in rodents as a drug model of schizophrenia. The current study investigated the cognitive effects of early postnatal PCP administration in C57BL/6 mice. Mouse pups received daily administrations of either 10.0 mg/kg PCP or saline on postnatal (PN) days 5-15. After weaning, pups were assessed in locomotor activity, a reference memory task in the Morris water maze, and a spatial delayed alternation task in the T-maze. Additionally, pups were subjected to a pharmacological challenge with PCP in the delayed alternation task. In males, No significant differences were detected between PCP- and saline-treated animals in locomotor activity. However, in the reference memory task, PCP-treated males had significantly longer path lengths, and displayed a non-significant trend towards increased thigmotaxia. Furthermore, males treated with PCP displayed significantly reduced accuracy in the working memory task without differences in choice latency, and were more sensitive to the acute effects of PCP than saline controls. Finally, these deficits were associated with a 29% increase in NR1 subunit expression in the hippocampus. Interestingly, PCP-treated female mice were not significantly different from saline-treated controls in locomotor activity, reference memory task performance, or delayed alternation performance, did not have a significantly different reaction to pharmacological challenge with PCP in the delayed alternation task, and did not demonstrate any changes in NR1 subunit expression. The present study provided the first evidence that early postnatal PCP administration in C57BL/6 mice can produce selective memory pairments. However, this effect was limited to the male mice, suggesting that the female mice were protected somewhat from these effects.

The aim was to highlight the context of developmental dysplasia therapy with postural hip locomotor development for children aged 4 weeks to 12 months. General examination was carried out in 9 children with disabilities in hip joints, degrees IIa- III. without contractures of adductors. We investigated spontaneous activity, and spontaneous reactivity. We compared the clinical picture of hip joints with the ultrasound image. Investigation of spontaneous activity was done by aspection. The test of spontaneous reactivity was taken using video and photos. Experimental results of our study showed the incidence of pathology in the spontaneous activity of 88.89 % children. Spontaneous reactivity was pathology in all cases, with various tests are discussed in the work. Ultrasound findings correlated with clinical manifestation in 66,67 %, but we cannot say that the proportion of patients will generally be higher than 60 %. Hypotheses were tested using the relative frequency parameter. The results are further discussed and compared with the assumptions by other authors. Powered by TCPDF (www.tcpdf.org)

Title: Functional disorders of the musculoskeletal system on individuals after kindey transplantation Defining of the problem: Renal transplantation is a method to treat patients with renal failure,which is associated to a prolonged survival of patients compared to a dialysis method (Viklický et al., 2008). After a successful renal transplantation the renal function is restored and complications caused by dialysis treatment disappear . However, complications due to the transplant, not only in terms of surgical intervention, but also from the point of a lifelong immunosuppressive therapy remain at risk. Functional changes on the locomotor system can occur as a concequence of a long-term renal disease or kidney transplant. This could further reduce the quality of life on patients due to self-sufficiency, being the main role of the locomotor system. Objectives: The aim of this study is to valuate functional disorders of the musculoskeletal system on individuals after kindey transplantation up to one year after a transplant. Methods: This thesis is elaborated in the form of an analytical - experimental study in which 2 groups of selected individuals were tested. Testing was conducted by using suitable tests focused on functional disorders of the locomotor system and parameters in each group and time...

Le système nerveux central possède des réseaux de neurones capables de générer des commandes motrices rythmiques en l'absence d'informations sensorielles. Ces réseaux neuronaux sont communément appelés générateurs centraux de patron (CPG, central pattern generator) et sont impliqués dans plusieurs fonctions et comportements vitaux tels que la locomotion et la respiration. Dans certaines circonstances, ces réseaux neuronaux se doivent d'interagir afin de produire un comportement moteur adapté aux contraintes environnementales ainsi qu'aux exigences de l'organisme. C'est notamment le cas lors d'un effort physique où une augmentation du rythme respiratoire est rapidement observée pour subvenir aux besoins en oxygène de l'organisme. Dans ce contexte de neurosciences intégratives, mon travail doctoral a porté sur l'étude des mécanismes neurogènes responsables de l'interaction entre les CPG respiratoires du tronc cérébral et les CPG locomoteurs de la moelle épinière. Cette étude a été réalisée sur des préparations de tronc cérébral-moelle épinière isolée in vitro de rat nouveau-né (P0 à P2) au sein desquelles les centres respiratoires et locomoteurs sont conservés intacts. Par des approches électrophysiologique, pharmacologique, lésionnelle et neuroanatomique, les mécanismes de coordination entre ces sous-groupes neuronaux ont été étudiés. Dans ce contexte, un des principaux résultats de ce travail doctoral est la mise en évidence de l'existence d'une influence ascendante excitatrice issues des CPG locomoteurs spinaux sur les centres respiratoires, et plus particulièrement sur le groupe respiratoire parafacial, structure située dans le bulbe rachidien et impliquée dans la genèse de la commande respiratoire. Outre son implication dans la modulation du rythme respiratoire, cette influence ascendante module également l'activité des populations neuronales expiratoires des régions spinales thoraciques et lombaires. Ces données constituent la première mise en évidence de l'existence de neurones bi-fonctionnels au sein de la moelle-épinière chez le rat nouveau-né. / The central nervous system contains neural networks that can generate rhythmic motor drive in absence of sensory feedback. These neural networks are commonly called central pattern generators (CPG) and are involved in many vital functions and behaviors, such as locomotion or respiration. In certain circumstances, these neural networks must interact to produce motor behaviors adapted to environmental constraints and the basic needs of organism. This is the case during physical exercise when the respiratory frequency increases in order to satisfy the oxygen needs. In a context of integrative neurosciences, my doctoral work aimed at exploring the neurogenic mechanisms involved in the coordination between the medullary respiratory networks and the spinal locomotor CPG. To address this question, we used an isolated in vitro brain stem-spinal cord preparations from neonatal rats (0-2 days) in which the respiratory and the locomotor networks are kept intact. Using electrophysiological, pharmacological, lesional and neuroanatomical approaches, mechanisms involved in the coordination between locomotor and respiratory rhythms have been studied. The major finding of this doctoral work is the identification of an ascending excitatory influence from spinal locomotor CPG to the respiratory networks, acting particularly on the parafacial respiratory group, which is known to be engaged in the genesis of expiratory activity. In addition to the respiratory frequency modulation, this ascending influence also modulates the activity of spinal expiratory neurons located in lumbar and thoracic segments. These data provide the first evidence for the existence of bi-functional neurons in newborn rat spinal cord.

Doenças como a dengue, chikungunya, Zika e febre amarela urbana são causadas por patógenos transmitidos pela picada de fêmeas infectadas de Ae. aegypti e Ae. albopictus. Fatores bióticos, como a competição na fase larval, e abióticos, como a variação da temperatura, provocam alterações no ciclo de desenvolvimento dessas espécies. O presente estudo avaliou os efeitos da competição intraespecífica e da temperatura na atividade locomotora de fêmeas virgens de Ae. aegypti e Ae. albopictus. Os objetivos do trabalho foram: comparar o tamanho das fêmeas de Ae. aegypti e Ae. albopictus oriundas de criadouros com baixa e alta competição intraespecífica; avaliar o efeito da competição intraespecífica na atividade locomotora de fêmeas virgens de Ae. aegypti e Ae. albopictus, sob regime de 12 horas de claro e 12 horas de escuro, à 25ºC e analisar o padrão da atividade locomotora de fêmeas virgens de Ae. aegypti e Ae. albopictus, sob regime de 12 horas de claro e 12 horas de escuro, sob diferentes temperaturas (20ºC, 25ºC e 30ºC). As colônias dos mosquitos utilizados nos experimentos são provenientes da FIOCRUZ-RJ. Para o experimento de competição, larvas de ambas as espécies foram criadas sob condições de alta (100 larvas) e baixa (20 larvas) densidades. Para isso, foram utilizadas 14 bacias preenchidas com 500 ml de água e 0,2 g de ração para peixes. Após a competição, as fêmeas oriundas de cada densidade foram transferidas para incubadoras para a realização da análise da atividade locomotora. Após a atividade, verificou-se o tamanho dos adultos oriundos de cada densidade larvária, por meio da medição das asas de cada fêmea. Para a análise da atividade locomotora sob diferentes temperaturas, as fêmeas utilizadas foram desenvolvidas em ambiente com quantidade de ovos similares. Foi utilizado o mesmo procedimento para análise da atividade do experimento anterior, porém, cada experimento ocorreu sob diferentes temperaturas: 20°C, 25°C e 30°C. Para a análise dos dados obtidos foram utilizados os testes T e ANOVA multifatorial. Para o experimento de competição, fêmeas de ambas as espécies oriundas de competição de baixa densidade foram maiores do que as oriundas de desenvolvimento sob alta densidade larvária. A atividade das fêmeas de Ae. aegypti e Ae. albopictus de ambas as densidades foi muito semelhante, sugerindo que fêmeas menores tem atividade equivalente à de fêmeas maiores. Já no experimento que avaliou a atividade das fêmeas sob faixas térmicas distintas, notou-se que, em Ae. aegypti, houve diferença significativa na atividade total sob 20°C quando comparadas a 25°C e 30°C, demonstrando que a temperatura mais baixa foi limitante para a atividade desta espécie. Houve diferenças em algumas médias avaliadas na atividade de Ae. albopictus, porém, esta espécie pareceu ter sido menos influenciada com a variação da temperatura. Análises estatísticas confirmaram que as fêmeas de Ae. aegypti respondem de forma distinta das fêmeas de Ae. albopictus quando as temperaturas foram modificadas. O presente estudo ajuda a esclarecer alguns aspectos relacionados ao comportamento dos mosquitos Ae. aegypti e Ae. albopictus, que são considerados de grande importância para a saúde pública. / Diseases such as dengue, chikungunya, Zika and urban yellow fever are caused by pathogens transmitted by the bites of infected females of Ae. aegypti and Ae. albopictus. Biotics factors essentially competition on larval stages, and abiotics factors, for instance, temperature variation, occasion adjustments on development cycle of these species. The present study evaluated the effects of intraspecific competition and temperature on locomotor activity of Ae. aegypti and Ae. albopictus. The aims of this study were: to compare the size of females Ae. aegypti and Ae. albopictus from breeding sites with low and high intraspecific competition; to evaluate the effect of intraspecific competition on locomotor activity of virgin females of Ae. aegypti and Ae. albopictus, under regime of 12 hours of light and 12 hours of dark at 25°C and to analyze the pattern of the locomotor activity of virgins females of Ae. aegypti and Ae. albopictus, under regime of 12 hours of light and 12 hours of dark, under different temperatures (20ºC, 25ºC e 30ºC). The mosquitoes colonies used on experiment are from FIOCRUZ-RJ. For the competition experiment, larvae from both species were raised under conditions of high (100 larvae) and low (20 larvae) densities. For this 14 containers filled with 500 ml of water and 0,2 g of fish food were used. After the competition, the females from each density were transferred to incubators to perform locomotor activity analysis. After the activity, the size of adult from each larval density, were verified by wings measurement of each female. For the analysis of the locomotor activity under different temperatures, the females used were developed in an environment with similar amount of eggs. The same procedure was used to the analyze the activity of the previous experiment, however, each experiment happened under different temperatures: 20°C, 25°C e 30°C. For the analysis of the obtained data were applied T tests and ANOVA multivariate. For the competition experiment, females of both species from low density of competition were longer than females from competition under high larval density. The activity of females of Ae. aegypti and Ae. albopictus from both densities was very similar, suggesting that smaller females have equivalent activity to that of larger females. In the experiment that evaluated the activity of females under different thermal bands, it was noticed that in Ae. aegypti there was significant difference in total activity under 20°C when compared with 25°C and 30°C degrees, demonstrating the lower temperature was limiting to activity for this species. There were differences in some averages evaluated in Ae. albopictus activity, however, this species seemed to have been less influenced with the temperature variation. Statistical analysis confirmed that females of Ae. aegypti respond differently than females of Ae. albopictus when the temperatures were modified. The present study helps to clarify some aspects about the behavior of mosquitoes Ae. aegypti and Ae. albopictus which are considered of great concern for public health.
