The afferent inputs from peripheral sensory receptors and efferent signals from the central nervous system that underlie intentional movement can contribute to kinesthetic perception. Previous studies have revealed that tendon vibration to wrist muscles elicits an excitatory response-known as the antagonist vibratory response-in muscles antagonistic to the vibrated muscles. Therefore, the present study aimed to further investigate the effect of tendon vibration combined with motor imagery on kinesthetic perception and muscular activation...

This study aims to evaluate if ligature-induced periodontitis can potentiates the deleterious effects of immobilization in the skeletal striated muscle, contributing to the development of muscle atrophy due to disuse. Forty Wistar rats were divided into four groups: (1) Control Group (CG), (2) Periodontal Disease (PDG), (3) Immobilized (IG), and (4) Immobilized with Periodontal Disease (IPDG). Periodontal disease was induced for 30 days, with ligature method, and the immobilization was performed with cast bandage for 15 days...

Bilirubin is known as a marker of hepatic dysfunction and is incorporated in scoring algorithms to assess prognosis in critically ill patients. No data are so far available on the prognostic role of hepatic dysfunction in patients with severe ARDS on venovenous extracorporeal membrane oxygenation (VV-ECMO) support. In 112 consecutive patients with severe ARDS treated with VV-ECMO, we aimed at assessing whether increased bilirubin during the first 72 h could affect early death. Increased serum bilirubin (≥1...

Duchenne muscular dystrophy (DMD) is a rare, fatal X-linked disorder characterized by the lack of dystrophin, a key sarcolemma muscle protein. Cardiac failure is a significant cause of death in DMD subjects. The purpose of our research was to identify potential cardiac serum biomarkers associated with DMD cardiomyopathy. This is an observational, case-controlled study using subjects from the CINRG DMD natural history study with cardiomyopathy (ejection fraction (EF) <55%; shortening fraction (SF) <28%), subjects without cardiomyopathy (EF ≥ 55%; SF ≥ 28%) compared to normal healthy volunteer subjects...

BACKGROUND: The dystroglycan complex consists of two subunits: extracellular α-dystroglycan and membrane-spanning β-dystroglycan, which provide a tight link between the extracellular matrix and the intracellular cytoskeleton. Previous studies showed that 43 kDa β-dystroglycan is proteolytically cleaved into the 30 kDa fragment by matrix metalloproteinases (MMPs) in various non-muscle tissues, whereas it is protected from cleavage in muscles by the sarcoglycan complex which resides close to the dystroglycan complex...

BACKGROUND: We previously studied the intramuscular innervation of 150 upper limb muscles and demonstrated that certain patterns of intramuscular innervation allowed muscles to be split into compartments with independent function. This study aims to determine the location, extra-muscular course, and number of motor nerve branches of upper limb peripheral nerves. We want to combine this information with our previous work to create a blueprint of upper limb neuromuscular anatomy that would be useful in reconstructive surgery...

INTRODUCTION: Many factors may contribute to running-related injury. These include fatigue and footwear, the combination of which has rarely been studied, in particular with reference to barefoot running, recently advocated as a method to reduce injury risk. METHODS: Twenty-two runners (12 well-trained and 10 trained) participated in a 10 km fatiguing trial. Knee and ankle joint kinematics and kinetics and electromyography were assessed during overground running in the barefoot and shod condition...

With the emerging interest in documenting and understanding muscle atrophy and function in critically ill patients and survivors, ultrasonography has transformational potential in measuring muscle quantity and quality. Here, we discuss the importance of quantifying skeletal muscle in the ICU setting. We also identify the merits and limitations of various modalities that are capable of accurately and precisely measuring muscularity. Ultrasound is emerging as a potentially powerful tool for skeletal muscle quantification; however, there are key challenges that need to be addressed in future work to ensure useful interpretation and comparability of results across diverse observational and interventional studies...

Whale tracking tags often penetrate semi-rigid blubber, with intramuscular sharp tips and toggling barbs under the subdermal sheath to reduce premature shedding. Tag sites can show persistent regional swellings or depressions. Fibroelastic blubber grips a tag, so if muscle shears relative to blubber during locomotion, the tag tip could cavitate the muscle within overall shearing distance. We modelled shearing of blubber relative to muscle, within the dorsal-ventral peduncular movement range of four common dolphin (Delphinus delphis) cadavers (mean length 186 cm)...

BACKGROUND: One in three children in North America are considered overweight or obese. Children with intellectual and developmental disabilities (IDD) are at an increased risk for obesity than their typically developing peers. Decreased physical activity (PA) and low physical fitness may be contributing factors to this rise in obesity. AIM: Because children with IDD are at an increased risk of diseases related to inactivity, it is important to improve health-related physical fitness to complete activities of daily living and improve health...

Congenital muscular dystrophies (CMD) are a group of heterogeneous disorders. Here, targeted next generation sequencing of 168 CMD-associated genes was performed on collected clinic samples to identify potential mutations. A loss-of-function mutation (c.4676-4682delGCTGCAA; p.Cys1560Thrfs*33) of the LAMA2 gene in a consanguineous family was identified and confirmed by Sanger sequencing. The second recessive mutation in SYNE1 (c.2881C>T; p.Arg961Trp) was found in the SAP motif, which was predicted to be involved in chromosomal organization...

BACKGROUND: Typing of Toxoplasma gondii strains is important in epidemiological surveys, to understand the distribution and virulence of different clones of the parasite among human and animal populations. Stray dogs can be consider sentinel animals for contaminated environments playing an important but probably under- evaluated role in the epidemiology of T. gondii. We reported a rare case of acute toxoplasmosis in a stray dog due to clonal type I infection. The clonal type I, sporadic in Europe, is frequently associated with severe toxoplasmosis in humans and the control of its circulation is particularly relevant for public health...

INTRODUCTION: To date, the ergonomics of flexible ureteroscopy (URS) have not been well described. We performed a study to assess the biomechanical stresses on urologists performing URS and to investigate the effect of ureteroscope type on these parameters. METHODS: Electromyography (EMG) was used to quantify the activation level of muscle groups involved in URS. Surface EMG electrodes (Delsys, Boston, MA) were placed on the right and left thenar, flexor carpi ulnaris (FCU), extensor carpi ulnaris (ECU), biceps, triceps and deltoid...

Even though positive relations between children's motor ability and their academic achievement are frequently reported, the underlying mechanisms are still unclear. Executive function has indeed been proposed, but hardly tested as a potential mediator. The aim of the present study was therefore to examine the mediating role of executive function in the relationship between motor ability and academic achievement, also investigating the individual contribution of specific motor abilities to the hypothesized mediated linkage to academic achievement...

BACKGROUND: Patients with secondary unilateral cleft lip are regularly affected by serious nasal deformities especially of the alar and nasal floor. A large number of techniques for correction have been published, but symmetrical restoration of severe nasal deformation is difficult to achieve. We propose an innovative approach for anatomical restoration for this entity of nasal deformities to achieve long-term symmetrical appearance and muscular function. METHODS: A total of 68 patients with severe nasal deformity due to secondary unilateral cleft lip underwent reconstructive surgery using a double composite tissue Z-plasty technique for anatomical restoration of cartilage, muscle, and soft tissue layers...

Although it has been widely accepted that Mg has a positive effect on muscle function, studies on the efficacy of Mg supplementation in young athletes have generated contrasting results. The aim of this work was to examine the effect of Mg supplementation on muscular damage markers and the association between serum Mg levels with these muscular markers. Twelve elite male basketball players (PB) from a team of Spanish Professional Basketball League and a control group (CG) comprising twelve university students who practiced regularly recreational basketball and competed in minor university leagues participated in this study...
