The purpose of this study was to provide a descriptive assessment of the nutritional habits of resistance trained males in relation to protein and carbohydrate intakes in comparison with the recommended values. Thirty-four male bodybuilders (27.0 +/- 2.1years, 173.5 +/- 5.0 cm, 8.3 +/- 0.61% body fat), twenty-four male weight lifters (20.9 +/- 2.1years, 171.8 +/- 6.9 cm, 7.6 +/- 0.98% body fat) and twenty-five male non-athletes (26.9 +/- 2.5years, 175.3 +/- 5.7 cm,, 8.5 +/- 0.95% body fat) participated in the study. Participants completed a comprehensive survey by twenty-four hour dietary recall methods. All diets were analyzed using the Computer Aided Nutritional (Pro) analyzer by a registered dietician. Body fat was measured using skin fold thickness. The average time spent in resistance training was 18.0 +/- 1.7 hrs/week for body builders and 14.6 +/- 8.7 hrs/week for weight lifters. Total daily calories were 2583.6 +/- 874.8 kcal (31.9 +/- 11.9 kcal/ kg) for bodybuilders, 3565.9 +/- 1281.8 kcal (42.7 +/- 15.0 kcal/kg) for weight lifters and 2016.0 +/- 955.3 kcal (28.1 +/- 13.9 kcal/kg) for non-athletes (p = 0.001). Percent of calories from carbohydrate, protein, and fat 64.2%, 27.1%, and 8.7% for bodybuilders, and 66.3%, 18.6%, and 15.1% for weight lifters. The mean protein intake was 1.9 +/- 1.2 g/ kg of BW for bodybuilders, 1.6 +/- 0.6 g/kg of BW for male weight lifters and 1.1 +/- 0.69 g/kg of BW for non-athletes. Although dietary calcium (78.7%) and riboflavin (86.3%) intakes for bodybuilders were below the RDA, dietary intakes of micronutrients were not deficient. More research needs to be conducted to determine the optimal amounts of protein, carbohydrates, fats, and micronutrients for the resistance trained athletes.

OBJECTIVE: To investigate the difference of range of motion (ROM) of ankle according to pushing force, gender and knee position. METHODS: One hundred and twenty-eight healthy adults (55 men, 73 women) between the ages of 20 and 51, were included in the study. One examiner measured the passive range of motion (PROM) of ankle by Dualer IQ Inclinometers and Commander Muscle Testing. ROM of ankle dorsiflexion (DF) and plantarflexion (PF) according to change of pushing force and knee position were measured at prone position. RESULTS: There was significant correlation between ROM and pushing force, the more pushing force leads the more ROM at ankle DF and ankle PF. Knee flexion of 90° position showed low PF angle and high ankle DF angle, as compared to the at neutral position of knee joint. ROM of ankle DF for female was greater than for male, with no significant difference. ROM of ankle PF for female was greater than male regardless of the pushing force. CONCLUSION: To our knowledge, this is the first study to assess the relationship between pushing force and ROM of ankle joint. There was significant correlation between ROM of ankle and pushing force. ROM of ankle PF for female estimated greater than male regardless of the pushing force and the number of measurement. The ROM of the ankle is measured differently according to the knee joint position. Pushing force, gender and knee joint position are required to be considered when measuring the ROM of ankle joint.

Ultrasound-guided peripheral nerve block has several advantages over traditional techniques for nerve localization. One is a reduction of local anesthetic dose required for successful nerve block, which might allow bilateral brachial plexus block to be performed without risk of local anesthetic toxicity. Another advantage is the ability to detect anatomical variations in nerve and vascular anatomy. We report the case of a patient with unilateral anatomical variations of the musculocutaneous nerve found in ultrasound-guided bilateral axillary brachial plexus block.

OBJECTIVE: To investigate the effects of a shoulder sling on balance in patients with hemiplegia. METHODS: Twenty-seven hemiplegic stroke patients (right 13, left 14) were enrolled in this study. The subjects' movement in their centers of gravity (COGs) during their static and dynamic balance tests was measured with their eyes open in each sling condition-without a sling, with Bobath's axillary support (Bobath sling), and with a simple arm sling. The percent times in quadrant, overall, anterior/posterior, and medial/lateral stability indexes were measured using a posturography platform (Biodex Balance System SD). Functional balance was evaluated using the Berg Balance Scale and the Trunk Impairment Scale. All balance tests were performed with each sling in random order. RESULTS: The COGs of right hemiplegic stroke patients and all hemiplegic stroke patients shifted to, respectively, the right and posterior quadrants during the static balance test without a sling (p<0.05). This weight asymmetry pattern did not improve with either the Bobath or the simple arm sling. There was no significant improvement in any stability index during either the static or the dynamic balance tests in any sling condition. CONCLUSION: The right and posterior deviations of the hemiplegic stroke patients' COGs were maintained during the application of the shoulder slings, and there were no significant effects of the shoulder slings on the patients' balance in the standing still position.

OBJECTIVE: To examine the association between motor evoked potentials (MEPs) in lower limbs and ambulatory outcomes of hemiplegic stroke patients. METHODS: Medical records of hemiplegic patients with the first ever stroke who received inpatient rehabilitation from January 2013 to May 2014 were reviewed. Patient who had diabetes, quadriplegia, bilateral lesion, brainstem lesion, severe musculoskeletal problem, and old age over 80 years were excluded. MEPs in lower limbs were measured when they were transferred to the Department of Rehabilitation Medicine. Subjects were categorized into three groups (normal, abnormal, and absent response) according to MEPs findings. Berg Balance Scale (BBS) and Functional Ambulation Category (FAC) at initial and discharge were compared among the three groups by one-way analysis of variance (ANOVA). Correlation was determined using a linear regression model. RESULTS: Fifty-eight hemiplegic patients were included. BBS and FAC at discharge were significantly (ANOVA, p<0.001) different according to MEPs findings. In linear regression model of BBS and FAC using stepwise selection, patients' age (p<0.01), BBS at admission (p<0.01), and MEPs (p<0.01) remained significant covariates. In regression assumption model of BBS and FAC at admission, MEPs and gender were significant covariates. CONCLUSION: Initial MEPs of lower limbs can prognosticate the ambulatory outcomes of hemiplegic patients.

BACKGROUND: Epstein Barr virus (EBV) infected B cells are transformed into lymphoblastoid cell lines. Some researchers suggested some a few similarities between this process and carcinogenesis. We observed the expression of CD80 and CD86, co-stimulatory molecules on EBV-transformed B cells and changes of CD54 expression after stimulation of CD80 and CD86. METHODS: CD80 and CD86 were stimulated using anti-CD80 and anti-CD86 monoclonal antibodies. To assess apoptosis and surface protein expression, flow cytometric analysis was performed. Intracellular signal molecules were evaluated by RT-PCR and immunoblot. Morphology and localization of proteins were examined using inverted or confocal microscope. RESULTS: Cross-linking of CD80 and CD86 induced apoptosis and interfered with proliferation of EBV-transformed B cells, and dispersion of clumped cells. We also examined that their stimulation induced ROS accumulation and reduced CD54 expression. Interestingly, we observed that CD80 and CD86 diminished the expression of CD54 in different methods. Both CD80 and CD86 down-regulated activation of focal adhesion kinase. CD80 stimulus inhibited CD54 expression through mainly RhoA inactivation, while CD86 down-regulated Ras and JNK phosphorylation. CONCLUSION: These results suggest that co-stimulatory CD80 and CD86 molecules, expressed EBV-transformed B cells, may play a role in apoptosis and cell adhesion.

BACKGROUND: Melanoma is the most fatal form of skin cancer due to its rapid metastasis. Recently, several studies reported that selenium can induce apoptosis in melanoma cells. However, the precise mechanism remains to be elucidated. In this study, we investigated the effect of selenium on cell proliferation in murine melanoma and on tumor growth and metastasis in C57BL/6 mice. METHODS: Cell proliferation was measured by MTT assay in selenium-treated melanoma cells. Cell cycle distribution was analysized by staining DNA with propidum iodide (PI). mRNA and protein expression related to cell cycle arrest was measured by reverse transcription PCR and western blot. Tumor growth and metastasis was measured by in vivo model. RESULTS: Selenium was suppressed the proliferation of melanoma cells in a dose dependent manner. The growth inhibition of melanoma by selenium was associated with an arrest of cell cycle distribution at G0/G1 stage. The mRNA and protein level of CDK2/CDK4 was suppressed by treatment with selenium in a time-dependent manner. In vivo, tumor growth was not suppressed by selenium; however tumor metastasis was suppressed by selenium in mouse model. CONCLUSION: These results suggest that selenium might be a potent agent to inhibit proliferative activity of melanoma cells.
