Persons unable to exercise due to old age, immobility or medical condition may develop low bone density, decline in muscle contraction, blood pooling or clot. Due to musculoskeletal fragility caution is required in bone and muscle strengthening. Similarly, caution is required to use anticoagulant drug to prevent blood clot due to side effect, and compression devices are not as effective as drug. This paper presents a transcutaneous muscle fiber excitation system adaptable for use in seated, walking or lying position...

INTRODUCTION: Early ambulation is the principal objective in trans-femoral amputees. Postamputation modifications complicate the rehabilitation process due to a reduced control at the interface between stump and prosthesis. The aim of this study is to determine whether magnetic resonance imaging depicts the amount of fatty degeneration of the thigh muscles after trans-femoral amputation (TFA). METHODS: A total of 12 patients following a TFA on the basis of a bone neoplasm or metastasis with an evaluable postoperative MRI were identified...

Vaccines often contain adjuvants to strengthen the response to the vaccine antigen. However, their modes of action at the site of injection (SOI) are poorly understood. Therefore, we assessed the local effects of adjuvant on the innate immune system in mice. We investigated the safe, widely used adjuvants MF59 and aluminum hydroxide (alum), as well as trehalose-6,6'-dibehenate (TDB), Complete Freund's Adjuvant (CFA) and the Toll-Like-Receptor-ligands lipopolysaccharide (LPS) and Pam3CysSerLys4 (Pam3CSK4). We assessed muscle immune cell infiltration after adjuvant injection and observed 16h post immunization (hpi) an increased influx with CFA, MF59 and TDB, but not with alum, LPS or Pam3CSK4...

Compared to aerobic-based physical activity, less research has evaluated the effects of muscle-strengthening physical activity (MSPA) on mortality. Additionally, limited research has evaluated this among adults with mobility limitations, which was this study's purpose. Data from the 2003-2006 NHANES, with follow-up through 2011, were used (analyzed in 2016). MSPA was assessed via self-report, with all-cause, CVD-specific, and cancer-specific mortality assessed as the outcome variables. Analyses were limited to adults with mobility limitations (N=1411), assessed via a validated questionnaire...

The rotator cuff (RC) insertions according to most anatomical texts are described as being separate from one another. However, clear fusion of the RC tendon fibres exists with prior studies showing this interdigitation forming a common, continuous insertion onto and around the lesser and greater tubercles (LT and GT) of the humerus. Current surgical repair methods (especially arthroscopic techniques) rarely mention or consider these connections during repair and suture anchor implantation. The general principles of RC surgery remain a controversial subject, due to various available techniques, surgeon experience and preference, and the contradicting success rates...

Abbas Bagheri, Mohaddese Feizi
Moebius syndrome is characterized by congenital facial palsy and limitation in horizontal gaze. The surgical results of the exotropic pattern are rare and have not been published before. The authors report three cases of exotropic Moebius syndrome. Maximal weakening of the lateral rectus muscles followed by strengthening of the medial recti in exotropic Moebius syndrome can improve exotropia significantly. Most of these cases also need some measures to relieve the often associated severe dry eye. [J Pediatr Ophthalmol Strabismus...

PURPOSE: Plication is a muscle-strengthening procedure in which a muscle is not dissected from its point of insertion. The purpose of this study was to compare the results of plication-recession (PR) with those of resection-recession (RR) in adult patients with intermittent exotropia (XT). METHODS: Patients with XT who underwent either PR or RR with a minimum postoperative follow-up of 12 months were retrospectively reviewed. Postoperative mean distance deviation and surgical outcomes were compared at 1 week and at 1, 3, 6, and 12 months, and at the final follow-up...

A direct link between development of insulin resistance and the presence of chronic inflammation, in case of obesity exists, with cytokines playing an important role in glucose metabolism. Members of TGF-β superfamily, including bone morphogenetic proteins (BMPs), have been shown to be involved in islet morphogenesis, establishment of β-cell mass and adipose cell fate determination. Here, we demonstrate a novel and direct role of BMP-4 and -7 in the regulation of glucose homeostasis and insulin resistance...

Studies have suggested a compromised postural control in individuals with knee osteoarthritis (OA) evidenced by larger and faster displacement of center of pressure (COP). However, quantification of postural control in the mini-squat posture performed by patients with early knee OA and its relation to muscle strength and self-reported symptoms have not been investigated. The main aim of this cross-sectional, observational, controlled study was to determine whether postural control in the mini-squat posture differs between individuals with early knee OA and a control group (CG) and verify the relation among knee extensor torque (KET) and self-reported physical function, stiffness and pain...

Small insects drive their flight muscle at frequencies up to 1,000 Hz. This remarkable ability owes to the mechanism of stretch activation. However, it remains unknown as to what sarcomeric component senses the stretch and triggers the following force generation. Here we show that the earliest structural change after a step stretch is reflected in the blinking of the 111 and 201 reflections, as observed in the fast X-ray diffraction recording from isolated bumblebee flight muscle fibers. The same signal has also been observed in live bumblebee...

BACKGROUND: Chest-wall contouring surgery is one of the first steps in sexual reassignment in female-to-male (FtM) transsexuals that contributes to strengthening of the self-image and facilitates living in the new gender role. The main goal is to masculinize the chest by removing the female contour. Chest contour, scar placement, scar shape, scar length, nipple-areola position, nipple size and the areola size are the key points. METHODS: Between July 2013 and June 2016, 25 FtM transgender patients underwent surgical procedures to create a masculine chest-wall contour...
