The purpose of the study was to investigate the effects of nordic walking on body composition and physical fitness in obese women with intellectual disability(ID). The subjects in experimental group(n=12) participated in nordic walking program for 12 weeks while those in control group(n=9) was controled not to participate in physical activities. After the training, weight, muscle mass and fat mass% showed significant improvement in experimental group. In physical fitness, strength, balance and coordination in experimental group showed significant improvement. In conclusion, these results suggest that nordic walking can be recommended as an effective intervention program to change body composition and to improve physical fitness in obese women with ID.

The current review seeks to highlight the concerns that have been raised on pre-slaughter stress, contributing factors and its consequent effects on cattle behavioural responses and the quality of beef; inter-linking the activities involved from birth to slaughter. Such information is crucial in light of the consumer concerns on overall animal welfare, quality of meat and food security. Slaughter animals are exposed to different conditions during production and transportation to abattoirs on a daily basis. However; the majority of studies that have been done previously singled out different environments in the meat production chain, while conclusions have been made that the welfare of slaughter animals and the quality of meat harvested from them is dependent on the whole chain. Behaviour is a critical component used to evaluate the animals' wellbeing and it has been reported to have an effect on product quality. Apart from the influence of on-farm, transportation and abattoir conditions, the genetic background of the animal also affects how it perceives and responds to certain encounters. Stress activates the animals' hypothalamic-pituitary-adrenal activity, triggering release of various stress hormones such as catecholamines and cortisol, thus glycogen depletion prior slaughter, elevated ultimate pH and poor muscle-meat conversion. Pre-slaughter stress sometimes results to cattle attaining bruises, resulting to the affected parts of the carcass being trimmed and condemned for human consumption, downgrading of the carcass and thus profit losses.

In this study, we studied the effect of dissolved cement powder on Carassius auratus by analysis of the morphophysiological changes. The gill exposed to dissolved cement powder showed the thickened primary lamellae and the activity of chloride cells and mucous cells was also significantly increased and the proliferation, separation and clubbing of gill filament was observed in the secondary lamellae. In the kidney tissue, the space in Bowman's capsule was widen and the arrangement of dermis was irregular due to the thinned epidermis in the integument tissue. The activities of antioxidant enzymes and LDH tended to increase with the duration of cement exposure. It was confirmed that the up-regulated proteins were identified as involved in glycolysis and energy metabolism and down-regulated proteins were myofibrillar proteins which were involved in muscle contraction by the cement exposure to the integument. With these results, dissolved cement powder was thought to be a big threat to the survival of the fish because it causes the morphological changes and weakens the physiological activity in C. auratus tissues.

The purpose of this study lies in finding out the effect that variation of pain and body deflection posture has an influence on the static spinal stabilization after having performed spinal stabilization exercise making degenerative disc disease patients an object over 8 weeks using $CENTAUR^{(R)}$, 3-D spinal stabilization training implement. Subjects : 61 of DDD patients were made as an object of this study (mean age: 45.46 years, SD: ${\pm}12.78$, range: 16-68), their average height was 161.87cm, average weight 60.70kg, 12 males and 49 females were involved. Methods: 8 various investigations were performed and varied values were compared with reinvestigation done after having exercised 8 weeks using 3-D $CENTAUR^{(R)}$. We used VAS(Visual Analog Scale) in order to see the variation of pain intensity, MOS(Modified Oswestry Scale) in order to see activities of daily life. Results VAS was lessened from 7.50 to 2.71, limitation of routine life(MOS) from 20.26 to 9.32, there were remarkable differences statistically(p<0.05). As a result of muscular investigation for static spinal stabilization by 8 variations of body deflection, muscular strength were all increased and there were remarkable differences statistically(p<0.05). Conclusions : It has been turned out that pain and limitation of daily life was lessened as a result of making 61 of degenerative disc disease patients exercised 8 weeks using $CENTAUR^{(R)}$, 3-D spinal stabilization training implement, deep muscular power was increased. Thus it has been turned out that 3-D lumbar stabilization exercise has an effect on the spinal muscles strengthening and alleviation of their pain for degenerative disc disease.

Although conservative management of congenital muscular torticollis (CMT) has been well documented, relatively little is known about the response to the treatment. The purposes of this case report were to describe the use of a therapeutic approach based on motor development in physical therapy intervention for an infant with CMT and to report the result of the treatment. The patient was a 20-day-old baby boy with left CMT presenting muscular mass in the left sternocleidomastoid muscle. The angle of the lateral head tilt was 20 degrees. The size of muscular mass was 5.3 mm in ultrasonography. Intervention included ultrasonic therapy, soft tissue massage, passive and active range of motion exercises, motor developmental therapy, and parent instruction. The procedures of motor developmental therapy and changes in the amount of lateral head tilt were documented using photography. The size of the mass was decreased to .3 mm before the 5-month follow-up. The patient also maintained a midline head position in the supine position and a midline head alignment during all functional activities. A therapeutic approach based on motor development is a beneficial method for reducing an asymmetrical head and neck position, and facilitating normal development as a component of physical therapy intervention.

Objective: The aim of the present study was to determine the effect of supplementing pasture-finished steers with corn silage on the expression level of the calpain system proteins and beef tenderization. Methods: Thirty Braford steers grazing on summer pasture were used for the study. For 120 days fifteen animals were supplemented with corn silage at 1% of body weight per head per day (Suppl) whereas the remaining 15 steers only received pasture (Contr). Carcass and meat traits were evaluated and compared between groups. Gene expression and activities of proteases (calpain 1 and calpain 2) and inhibitor (calpastatin) were measured using real-time polymerase chain reaction and casein zymography. Results: Carcass and meat traits were significantly different between feeding systems. Supplemented steers showed higher hot carcass weight (p<0.01), fat content (p = 0.02), and Warner-Bratzler shear force (p = 0.03). Furthermore, the control group showed higher protease:inhibitor ratios, at mRNA (p = 0.01) and protein levels (p<0.10). Warner-Bratzler shear force and mRNA calpains:calpastatin ratio were associated in both feeding systems (p<0.01). Conclusion: Based on the results obtained in the study, beef tenderness differences among finishing strategies could be modulated through differential expression of the calpain system proteins.

The aim of the present study was to evaluate the possible roles of hyperforin against hyperglycemia, hyperlipidemia and oxidative stress in streptozotocin-induced diabetic rats. Diabetes was induced by a single intraperitoneal injection of streptozotocin (65 mg/kg). Biochemical parameters were measured following hyperforin treatment (10 mg/kg, i.p.) for 7 days. Hyperforin treatment significantly reversed the elevations in plasma glucose, triglycerides, total cholesterol and LDL-cholesterol. Hyperforin also reversed the declines in plasma HDL-cholesterol and liver glycogen, but did not reverse the change in plasma insulin levels when compared to the diabetic control rats. Hyperforin treatment also reversed the oxidative stress induced by streptozotocin. Moreover, the effect of the hyperforin on peripheral glucose utilization in normal rats was evaluated by an oral glucose tolerance test (OGTT). Hyperforin treatment significantly increased (p < 0.05) the glucose tolerance compared to the vehicle in OGTT. The antihyperglycemic, antihyperlipidemic and antioxidant activities of hyperforin (10 mg/kg, i.p.) were comparable qualitatively to glibenclamide (1 mg/kg, p.o.). In conclusion, we report for the first time through an in vivo study that hyperforin is potentially valuable for the treatment of diabetes and its associated hyperlipidemia and oxidative stress by enhancing the glucose utilization by peripheral tissues such as muscle and adipose tissues.

The purpose of this study was to determine the effect of the foot rotation on the lower limb muscles. Fourteen subjects performed step-up/step-down at a cadence of 80 beats/min, exercises with the foot neutral, $35^{\circ}$ internally rotated, and $35^{\circ}$ externally rotated, respectively. For each variable, a one-way analysis of variance (ANOVA) was used to determine whether there were significant differences between genders and among the eight types of jump. When a significant difference was found in jump type, post hoc analyses were performed using the Tukey procedure. A confidence level of p < .05 was used to determine statistical significance. The results showed that significant changes in averaged IEMG values occurred with the internal rotation of the foot in the lateral gastrocnemius during the knee extension, and in the semitendinosus during the knee flexion. During the knee extension, however, the internal rotation of the foot produced a significantly lower Averaged IEMG values than the neutral foot position in the medial gastrocnemius. The results also found that the peak IEMG activity of the rectus femoris during the knee extension for the external rotation of the foot was Significantly higher than the corresponding values in the neutral position of the foot, while the intenal rotaion of the foot exhibited a significant difference with the neutral position of the foot in the semitendinosus during the knee flexion. In general, the foot rotation position did not influence the average IEMG and Peak IEMG values of most muscles. The practice of adopting foot rotation to selectively strengthen individual muscles of the lower limb was not supported by this study. The external rotation of the foot produced high muscle activities in the quadriceps during the knee extension. For the knee extension, therefore, maintaining a laterally rotated position should be need for stable and comfortable position.

Purpose: The purpose of this study was to evaluate the clinical results of the old Achilles tendon rupture treated with modified flexor hallucis longus (FHL) tendon transfer. Materials and Methods: Seventeen patients with old Achilles tendon rupture treated with modified FHL tendon transfer between March 2004 and February 2008 were enrolled in this study. Technically FHL was pass through the distal portion of the ruptured tendon instead of the drilled hole made on the calcaneus. The mean age of the patients was 37 years (range, 22~67 years), mean follow-up period was 28 months (range, 12~30 months). Patients' subjective satisfaction, calf circumferential diameter, range of motion of ankle and AOFAS ankle-hind foot score and Arner-Lidholm score was evaluated. Results: The average gap between the ruptured tendon was 52 mm (range, 47~56 mm). The AOFAS score improved from 47 pre-operatively to 91 points at the last follow-up. Sixteen patients were satisfied with the result free from discomfort, a patient had mild discomfort who had DM. fourteen patients had decreased range of motion less than 5 degrees while 2 patients had more than 7 degrees decrease compared to the intact side but had no discomfort in daily activities. Nine patients had less than 1 cm calf circumferential diameter difference and 7 patients had 1 to 3 cm diameter difference compared to the intact side. One who had more than 3 cm diameter difference had deteriorated muscle strength. Conclusion: Modified FHL tendon transfer can be a useful technique for the treatment of old Achilles tendon rupture when the gap is with large gap placed too proximal.

Exercise training (ET) and selenium (SEL) were evaluated either individually or in combination (COMBI) for their effects on expression of glucose (AMPK, PGC- $1{\alpha}$, GLUT-4) and lactate metabolic proteins (LDH, MCT-1, MCT-4, COX-IV) in heart and skeletal muscles in a rodent model (Goto-Kakisaki, GK) of diabetes. Forty GK rats either remained sedentary (SED), performed ET, received SEL, ($5\;{\mu}mol{\cdot}kg$ body $wt^{-1}{\cdot}day^{-1}$) or underwent both ET and SEL treatment for 6 wk. ET alone, SEL alone, or COMBI resulted in a significant lowering of lactate, glucose, and insulin levels as well as a reduction in HOMA-IR and AUC for glucose relative to SED. Additionally, ET alone, SEL alone, or COMBI increased glycogen content and citrate synthase (CS) activities in liver and muscles. However, their effects on glycogen content and CS activity were tissue-specific. In particular, ET alone, SEL alone, or COMBI induced upregulation of glucose (AMPK, PGC-la, GLUT-4) and lactate (LDH, MCT-1, MCT-4, COX-IV) metabolic proteins relative to SED. However, their effects on glucose and lactate metabolic proteins also appeared to be tissue-specific. It seemed that glucose and lactate metabolic protein expression was not further enhanced with COMBI compared to that of ET alone or SEL alone. These data suggest that ET alone or SEL alone or COMBI represent a practical strategy for ameliorating aberrant expression of glucose and lactate metabolic proteins in diabetic GK rats.
