Estocagem tecidual e utilização de lipídeos em Matrinxã, Brycon cephalus (Günther, 1869)

Lipids have important biological functions, suchas membrane constituents, hormone precursors, and are efficient energy reserves, due to thers high caloric content. In fish, but not in mammals, lipid storage patterns are quite diverse. The aim of this study was to determine lipid distribution in somatic and reproductive tissues of matrinxã, Brycon cephalus, both male and female, highlighting somatic indices related to lipid dynamics. From Oct 98 to Jan 99, a total of 174 fish (8-12 each month) were sampled. After fish anesthesia, heparinized blood was collected for plasma triacylglycerol determination. Fish were individually weighed and measured, and liver, gonads and visceral fat were collected and weighed for HSI (hepatosomatic index), GSI (gonad somatic index) and MFI (mesenteric fat index) calculation. The highest values of total lipids were found in red muscle (about 18%), liver and gonads (about 16.5%). The white muscle had a lower concentration (2.5%). Analyses of variance of HSI and MFI showed fluctuations along the experimental period with lowest concentrations in the periods of highest temperatures. Matrinxã store lipids in several body tissues, including mesenteric fat, liver, muscles and gonads.

Efeitos preventivos do exercício físico na expressão da miostatina em ratos tratados com Dexametasona

Muscle atrophy is always associated with Dexamethasone (Dexa) treatment, however the mechanisms are not completely understood. This study investigated the effects of Dexa on myostatin and p70S6K protein expression and if previous exercise training (T) can attenuate these effects. Eighty rats were distributed into 4 groups: sedentary control (SC), sedentary treated with Dexa (SD; 0,5 mg/kg per day, i.p., 10 days), trained control (TC) and trained treated with Dexa (TD) and underwent a training period where they were either submitted to a running protocol (60% of physical capacity, 5 days/week for 8 weeks) or kept sedentary. After T period, animals underwent Dexa treatment concomitant with training. Western Blot was performed to identify myostatin and p70S6k protein expression in the tibialis anterior (TA) and soleus (SOL) muscle. Ten days of Dexa treatment increased fasting glucose (SD=+62%), however previous T attenuated this increase (TD=+20%, p<0.05). Dexa determined significant decrease in body weight in TD (-22%) and SD (-25%), followed by TA weight reduction in SD (-23%) and TD (-20%). Previous training could not avoid these decreases. Myostatin protein expression was not altered by dexa treatment or training in TA muscle but in SOL muscle it was significantly modified after T, regardless of treatment (TC=+%23 and TD=+25) compared with their respective controls. The protein p70S6K was not modified neither by dexa nor training in any of the analyzed muscle or condition. The results of this study allowed us to conclude that previous training attenuates the hyperglycemia induced by Dexa, however it did not prevent the body or muscle weight reductions. Even in the presence of muscle atrophy, the expression of myostatin and p70S6K do not justify the mechanisms of muscle loss induced by Dexa, which suggests that other catabolic or anabolic proteins could be involved in the process of muscle atrophy after 10 days of treatment with Dexa

Natação Adaptada: análise da função pulmonar de pessoas com deficiência

The research discusses the pulmonary function of the students of SORRI that are part of the Project for the extension of the Department of Physical Education in Bauru Swimming for People with Disabilities during the aquatic activities, noting the changes in efficiency class of breathing with the practice of aquatic activity, by the analysis of the volume and respiratory capacity. The respiratory control is essential in the process of adaptation to the liquid medium, because a student who fails to immerse the face in the water will not be able to adopt a horizontal position sufficiently stable. The practice of aquatic activities requires a great effort of breathing. Therefore, the practice of aquatic activities influence favorably the breathing, because the movements performed in the water tone the diaphragm, which is the essential muscle of the breathing, allowing an improvement in pulmonary ventilation. For the purposes of this study, the sample was composed of 10 students of the SORRI of the city of Bauru forming part of the project Swimming for People with Disabilities, practicing swimming once a week for 1 hour. For the collection of lung volumes and capacities was used a transducer of air flow and a unit of data collection, model MP36, both of the brand Biopac connected to a computer, where the data were collected and recorded for later analysis. Two tests were carried out in a day with each participant in the project of swimming, and a test at the beginning of the lesson, at rest, and another after a series of 10 breaths carried out within the swimming pool. These tests were performed in the months of March and April. The analysis of the data was through the medium of the figures and also individually, noting the changes in respiratory function of students practicing aquatic activities, without which there would be no comparison between the participants. The measurements of the scores on the pre- and post-exercise show that the...

Histochemistry profile of the biceps brachii muscle fibres of capuchin monkeys (Cebus apella, Linnaeus, 1758)

A general analysis of the behaviour of "Cebus" shows that when this primate moves position to feed or perform another activity, it presents different ways of locomotion. This information shows that the brachial biceps muscle of this animal is frequently used in their locomotion activities, but it should also be remembered that this muscle is also used for other development activities like hiding, searching for objects, searching out in the woods, and digging in the soil. Considering the above, it was decided to research the histoenzimologic characteristics of the brachial biceps muscle to observe whether it is better adpted to postural or phasic function. To that end, samples were taken from the superficial and deep regions, the inserts proximal (medial and lateral) and distal brachial biceps six capuchin monkeys male and adult, which were subjected to the reactions of m-ATPase, NADH-Tr. Based on the results of these reactions fibres were classified as in Fast Twitch Glycolitic (FG), Fast Twitch Oxidative Glycolitic (FOG) and Slow Twitc (SO). In general, the results, considering the muscle as a whole, show a trend of frequency FOG>FG>SO. The data on the frequency were studied on three superficial regions FOG=FG>SO; the deep regions of the inserts proximal FOG=FG=SO and inserting the distal FOG>FG=SO. In conclusion, the biceps brachii of the capuchin monkey is well adapted for both postural and phasic activities.

Uso do soro autólogo condicionado e do plasma rico em plaquetas na terapia ortopédica de equinos

Musculoskeletal injuries that occur in horses during sports activities are often disabling and require a long period of treatment and rehabilitation, most resulting in scar tissue, predisposing to recurrence. In search of more effective therapies and tissue regeneration, studies have been carried out with blood derivatives - platelet rich plasma and autologous conditioned serum. In spite of both being blood-derived therapies, platelet rich plasma and autologous conditioned serum are distinct products, with equally distinct indications for their use. Platelet rich plasma shows promising results in ligament and tendon injuries in clinical and experimental trials. This occurs also in osteoarticular lesions with both hemoderivates, autologous conditioned serum and platelet rich plasma. This review aims to present clinical and experimental studies (in vivo and in vitro) in the equine species, as an aid for an appropriate therapeutic choice, when hemoderivates are considered for treatment of musculoskeletal lesions.

Caracterização molecular de bovinos de origem Bos indicus e seus cruzados para maciez de carne

O objetivo desse trabalho foi conhecer a variabilidade genética da calpaína e seu potencial como marcador molecular para programas de melhoramento genético, visando auxiliar na seleção de genótipos superiores para maciez de carne zebuína. Para tanto foram analisados 55 animais da raça Nelore, proveniente de outros projetos de pesquisa conduzidos pela equipe técnica do Laboratório de Genética do Instituto de Zootecnia de Nova Odessa. Os animais foram abatidos ao atingirem o acabamento de 4 mm de espessura de gordura e a amostra de carne foi coletada entre a 12ª e 13ª costelas no músculo Longissimus dorsi. A maciez de carne foi avaliada empregando-se a técnica de Warner Bratzler Shear Force em 0 e 14 dias de maturação. O DNA foi extraído a partir das amostras de carne, em seguida foi quantificado e diluído para ser amplificado por PCR. Três polimorfismos foram investigados pelas técnicas de PCR-RFLP e PCR- SSCP, localizados no exon 9, exon 14 e intron 17 do gene calpaína, sendo denominados CPN316, CAPN530, CAPN4751, respectivamente. Os resultados da análise de associação entre os dados de força de cisalhamento (FC) e marcadores moleculares revelaram efeito significativo apenas para o marcador CAPN4751. O alelo C, considerado favorável para maciez de carne, apresentou relação significativa (P>0,05) com valores menores de FC, sugerindo o seu emprego na seleção de genótipos superiores para maciez de carne de bovinos da raça Nelore

Efeito agudo do alongamento de diferentes grupos musculares no desempenho muscular de idosas

Among the numerous possibilities of physical exercise, it has been recommended that stretching routines should be incorporated into training programs focused on the elderly population, and that these routines should be preferentially performed on the same strength or aerobic training session. However, studies have shown that muscle strength production can be acutely impaired if it is preceded by static stretching exercises (AE). Although there seems to be a relationship between the number of stretched muscles and strength response, no studies were found examining such relationship in the same study, simultaneously. Thus, the objective of this study is to analyze the acute effect of stretching of different muscle groups on strength performance in older women. Nineteen physically active older women participated in the study (67.8 ± 5.3 years, 68.9 ± 12.4 kg, 157.2 ± 6.4 cm)-usar ponto final em inglês e não vírgula. The participants visited the lab for six consecutive days, three of which were intended to familiarization. Over the next three days, all the participants performed the experimental conditions: control; quadriceps stretching alone and complete stretching, involving the major extensors muscle groups of knees and hips. Both the two stretching conditions were realized with three series of 30s (total volume of 90 seconds for each exercise). All experimental conditions was be performed with an interval of at least 24 hours and order of execution was be randomized. The force transducer was connected to a leg press apparatus, where the isometric force time curve and electromyographic activity of the vastus medial and vastus lateralis were recorded. Measurements were registered immediately after each experimental condition, during five seconds. Statistical analysis comprised descriptive procedures and the One way ANOVA test for repeated measures (p<0.05). No statistically significant differences between the control and the two...
