Electromyographic reaction time in older female fallers and non-fallers after postural perturbation

O tempo de reação eletromiográfica (TRE) reflete a magnitude e a velocidade com que os músculos são ativados para realizar movimentos, evitar lesões ou posicionar uma articulação e pode ser avaliado após uma perturbação externa para análise do desempenho do controle postural e relacioná-lo com a possibilidade de quedas em idosos. O objetivo do estudo foi verificar o TRE dos músculos oblíquo interno (OI), reto femoral (RF), vasto lateral (VL), tibial anterior (TA), multífido (MU), glúteo máximo (GM), bíceps femoral (BF) e gastrocnêmio lateral (GL) em situações de perturbação do equilíbrio em idosos com e sem histórico de quedas. Para isso, foram avaliadas vinte e nove mulheres com 60 anos ou mais, fisicamente ativas e não-institucionalizadas e separadas em dois grupos de acordo com o relato de quedas nos 12 meses pregressos ao estudo: Grupo de Idosas Caidoras (GIC) (n=13; 72,4 ± 8,0 anos) e Grupo de Idosas Não-Caidoras (GINC) (n=16; 67,8 ± 6,8 anos). O TRE dos músculos avaliados durante o teste de desequilíbrio postural anterior e posterior não foram significativamente diferentes entre os grupos. Os resultados sugerem que a ativação muscular dos músculos avaliados, tanto durante o desequilíbrio anterior quanto no desequilíbrio posterior, não podem ser considerados um fator determinante para quedas.

Do muscle strengthening exercises improve performance in the 6-minute walk test in postmenopausal women?

Background: Walking speed seems to be related to aerobic capacity, lower limb strength, and functional mobility, however it is not clear whether there is a direct relationship between improvement in muscle strength and gait performance in early postmenopausal women. Objective: To evaluate the effect of muscle strengthening exercises on the performance of the 6-minute walk test in women within 5 years of menopause. Methods: The women were randomized into control group (n=31), which performed no exercise, and exercise group (n=27), which performed muscle strengthening exercises. The exercises were performed twice a week for 3 months. The exercise protocol consisted of warm-up, stretching, and strengthening of the quadriceps, hamstring, calf, tibialis anterior, gluteus maximus, and abdominal muscles, followed by relaxation. Muscular strength training started with 60% of 1MR (2 series of 10-15 repetitions), reaching 85% until the end of the 3-month period (4 series of 6 repetitions each). Results: The between-group comparisons pre- and post-intervention did not show any difference in distance walked, heart rate or blood pressure (p>0.05), but showed differences in muscle strength post-intervention, with the exercise group showing greater strength (p<0.05). In the within-group comparison, there were differences in final heart rate and quadriceps and hamstring strength pre- and post-intervention in the exercise group (p<0.05). Conclusion: The results suggest that muscle strengthening of the lower limbs did not improve performance in the 6-minute walk test in this population of postmenopausal women.

Costs and benefits of temporary brood desertion in a Neotropical harvestman (Arachnida: Opiliones)

Brood desertion is a life history strategy that allows parents to minimize costs related to parental care and increase their future fecundity. The harvestman Neosadocus maximus is an interesting model organism to study costs and benefits of temporary brood desertion because females abandon their clutches periodically and keep adding eggs to their clutches for some weeks. In this study, we tested if temporary brood desertion (a) imposes a cost to caring females by increasing the risk of egg predation and (b) offers a benefit to caring females by increasing fecundity as a result of increased foraging opportunities. With intensive field observations followed by a model selection approach, we showed that the proportion of consumed eggs was very low during the day and it was not influenced by the frequency of brood desertion. The proportion of consumed eggs was higher at night and it was negatively related to the frequency of brood desertion. However, frequent brood desertion did not result in higher fecundity, measured both as the number of eggs added to the current clutch and the probability of laying a second clutch over the course of the reproductive season. Considering that harvestmen are sensitive to dehydration, brood desertion during the day may attenuate the physiological stress of remaining exposed on the vegetation. Moreover, since brood desertion is higher during the day, when egg predation pressure is lower, caring females could be adjusting their maternal effort to the temporal variation in predation risk, which is regarded as the main cost of brood desertion in ectotherms.

Diversity of harvestmen (Arachnida, Opiliones) in Parque da Onca Parda, southeastern Brazil

The environment most diverse in harvestmen species is the Atlantic Forest of Sao Paulo. However, there remains a lack of studies regarding their communities in certain regions. Among these regions is one south of the Paranapiacaba mountain range in the state of Sao Paulo, the Parque da Onca Parda (POP). Through nocturnal collections and pitfall traps, the region's harvestmen community has been studied. The observed richness of this site included 27 species, with dominance of three species: Holcobunus nigripalpis Roewer, 1910, Neosadocus maximus (Giltay, 1928) and Munequita sp., accounting for 68.4% of harvestmen abundance. This makes the diversity of POP more similar to the semideciduous Atlantic Forest communities of the interior than to those of the Coastal Atlantic Forest that contains the park. Its geographic location places it within the Southern Sao Paulo State (SSP) area of endemism, along with the Parque Turistico do Alto Ribeira (PETAR), with which it shares up to 12% similarity regarding harvestmen fauna. Richness and abundance of harvestmen were positively related to temperature and humidity. The period of animal activity (as measured by abundance and richness) varied throughout the night, being highest in the early hours during both studied seasons (summer and winter).

Labyrinthum capellae. Le "Annotationes in Marcianum" di Giovanni Scoto Eriugena e la fortuna del neoplatonismo cristiano

The labyrinthum Capella quoted in the title (from a Prudentius of Troyes epistle) represents the allegory of the studium of the liberal arts and the looking for knowledge in the early middle age. This is a capital problem in the early Christianity and, in general, for all the western world, concerning the relationship between faith and science. I studied the evolution of this subject from its birth to Carolingian age, focusing on the most relevant figures, for the western Europe, such Saint Augustine (De doctrina christiana), Martianus Capella (De Nuptiis Philologiae et Mercurii) and Iohannes Scotus Eriugena (Annotationes in Marcianum). Clearly it emerges that there were two opposite ways about this relatioship. According to the first, the human being is capable of get a knowledge about God thanks to its own reason and logical thought processes (by the analysis of the nature as a Speculum Dei); on the other way, only the faith and the grace could give the man the possibility to perceive God, and the Bible is the only book men need to know. From late antiquity to Iohannes Scotus times, a few christian and pagan authors fall into line with first position (the neoplatonic one): Saint Augustine (first part of his life, then he retracted some of his views), Martianus, Calcidius and Macrobius. Other philosophers were not neoplatonic bat believed in the power of the studium: Boethius, Cassiodorus, Isidorus of Seville, Hrabanus Maurus and Lupus of Ferriéres. In order to get an idea of this conception, I finally focused the research on Iohannes Scotus Eriugena's Annotationes in Marcianum. I commented Eriugena's work phrase by phrase trying to catch the sense of his words, the reference, philosophical influences, to trace antecedents and its clouts to later middle age and Chartres school. In this scholastic text Eriugena comments the Capella's work and poses again the question of the studium to his students. Iohannes was a magister in schola Palatina during the time of Carl the Bald, he knew Saint Augustine works, and he knew Boethius, Calcidius, Macrobius, Isidorus and Cassiodorus ones too. He translated Pseudo-Dionysius the Areopagite and Maximus the Confessor. He had a neoplatonic view of Christianity and tried to harmonize the impossibility to know God to man's intellectual capability to get a glimpse of God through the study of the nature. According to this point of view, Eriugena's comment of Martianus Capella was no more a secondary work. It gets more and more importance to understand his research and his mystic, and to understand and really grasp the inner sense of his chief work Periphyseon.
