The current study investigated how bovine milk extracellular vesicles (EVs) affected rotarod performance and biomarkers of skeletal muscle physiology in young, growing rats. Twenty-eight-day Fisher 344 rats were provided an AIN-93G-based diet for 4 weeks that either remained unadulterated [EVs and RNA-sufficient (ERS; n = 12)] or was sonicated [EVs and RNA-depleted (ERD; n = 12)]. Prior to (PRE) and on the last day of the intervention (POST), animals were tested for maximal rotarod performance. Following the feeding period, the gastrocnemius muscle was analyzed at the histological, biochemical, and molecular levels and was also used to measure mitochondrial function and …

The development of effective nanosystems for drug delivery represents a key challenge for the improvement of most current anticancer therapies. Recent progress in the understanding of structure and function of extracellular vesicles (EVs)-specialized membrane-bound nanocarriers for intercellular communication-suggests that they might also serve as optimal delivery systems of therapeutics. In addition to carrying proteins, lipids, DNA and different forms of RNAs, EVs can be engineered to deliver specific bioactive molecules to target cells. Exploitation of their molecular composition and physical properties, together with improvement in bio-techniques to modify their content are critical issues to target them to specific cells/tissues/organs. Here, …

Power Output In Rugby Players Comparing Unilateral And Bilateral Isotonic Upper-Body Resistance Exercise, Evan Nakachi, James D. George, Allen Parcell, Dennis Eggett, Brent Feland
International Journal of Exercise Science
International Journal of Exercise Science 12(6): 691-700, 2019. Bilateral deficit (BLD) occurs when the internal muscular force generated during simultaneous bilateral limb exercise is lower than the sum of internal muscular forces generated during separate right limb and left limb unilateral exercise, while attempting to oppose the same total external load. Numerous BLD studies have evaluated force output differences during exercise; however, no study has determined whether BLD exists when generating power during isotonic upper-body exercise. To address this, we measured and compared power output across unilateral and bilateral isotonic upper-body exercise. Seventeen college male rugby players (age = 21.8 …

The Mexican axolotl (Ambystoma mexicanum) is an important model organism in biomedical research. Much current attention is focused on the axolotl's amazing ability to regenerate tissues and whole organs after injury. However, not forgotten is the axolotl's equally amazing ability to thwart aspects of tissue maturation and retain juvenile morphology into the adult phase of life. Unlike close tiger salamander relatives that undergo a thyroid hormone regulated metamorphosis, the axolotl does not typically undergo a metamorphosis. Instead, the axolotl exhibits a paedomorphic mode of development that enables a completely aquatic life cycle. The evolution of paedomorphosis allowed axolotls …

Lumen-apposing metal stents (LAMS) are increasingly being used in the drainage of pancreatic walled-off necrosis (WON). Best choice of stent is subject to argument, and studies are varied in the reported outcomes between LAMS and plastic stents (PS) to this end. We conducted a comprehensive search of multiple electronic databases and conference proceedings including PubMed, EMBASE, and Web of Science databases (earliest inception through July 2018) to identify studies that reported on the use of LAMS and PS in WON drainage. Studies published since the release of the revised Atlanta classification for pancreatic fluid collections (2014 to current) were included …

Trunk Muscle Activation During Dynamic Sling Training Exercises, Tobias Morat, Denis Holzer, Rieke Trumpf
International Journal of Exercise Science
International Journal of Exercise Science 12(1): 590-601, 2019. The purpose of this study was to examine the level of trunk muscle activation to characterize different dynamic sling training exercises. Thirty-six young adults (25±3 years, 1.78±0.1 m, 71.5±10.4 kg) performed six different sling training exercises while muscle activation of eight different trunk muscles was measured unilaterally by surface electrodes. Four of the exercises were conducted at two different difficulty levels (an easy and a hard version) by changing the body angle. The six sling training exercises differed regarding muscle activation, with significant differences (p< 0.05) between the three body parts (front, side, back). High muscle activations (76-87%) of the (front) trunk flexor muscles were measured. The back muscles tested reached more than half of their peak reference trial values only during one exercise tested. Regarding the side muscles, three of the sling exercises achieved muscle activations of 60% and higher (66-92%). All eight trunk muscles tested demonstrated a significantly (p< 0.05) higher muscle activation in the harder version compared with the easy version. Based on the results, the sling training exercises tested in this study seem to be most effective for the abdominal muscles. As assumed based on the former literature, changing the body angle during sling training exercises is shown to be a feasible way of adjusting the intensity of sling training. This could potentially be used in longitudinal sling training studies to assure a controlled, progressively increasing training intervention.

Dorsiflexion Range Of Motion In Copers And Those With Chronic Ankle Instability, Madison M. Vomacka, Melena R. Calhoun, Monica R. Lininger, Jupil Ko
International Journal of Exercise Science
International Journal of Exercise Science 12(1): 614-622, 2019. The Cumberland Ankle Instability Tool (CAIT) is used to classify individuals as ankle sprain copers, or as one suffering from chronic ankle instability (CAI). However, literature examining factors contributing to these classifications on the CAIT is lacking, as the CAIT itself does not offer explanations for specific anthropometric measures that influence a patient’s classification. Therefore, the purpose was to determine if there was a difference between dorsiflexion active range of motion (AROM) between copers, those with CAI, and a healthy control group. Twenty-two individuals with recent ankle sprains were recruited by a …

We generated an inducible, skeletal muscle-specific Dicer knockout mouse to deplete microRNAs in adult skeletal muscle. Following tamoxifen treatment, Dicer mRNA expression was significantly decreased by 87%. Wild-type (WT) and Dicer knockout (KO) mice were subjected to either synergist ablation or hind limb suspension for two weeks. There was no difference in muscle weight with hypertrophy or atrophy between WT and KO groups; however, even with the significant loss of Dicer expression, myomiR (miR-1, -133a and -206) expression was only reduced by 38% on average. We next aged WT and KO mice for ~22 months following Dicer inactivation to determine …
