Whereas static vocal fold medialization or lateralization are currently the standard procedures, new dynamic treatment methods such as reinnervation and laryngeal pacing focus on better toning and remobilization of the paralyzed vocal folds. End-to-end or jump anastomoses of the recurrent laryngeal nerve can preserve muscle mass and avoid atrophy, thus enabling subsequent dynamic therapeutic options. Prognostic evaluation and the time point of therapeutic intervention are important issues in the management of patients with recurrent laryngeal nerve paralysis...

Bothropic venom contains a range of biologically active substances capable of causing severe local and systemic envenoming symptomatology within its victims. The snake anti-venom is effective against systemic effects but has no neutralizing effect against the fast developing local effects. Herein, mice gastrocnemius injected with Bothrops moojeni venom (40 μg/kg) or saline solution were irradiated with HeNe (632.8 nm) and GaAs (904 nm) lasers (daily energy density of 4 J/cm(2); 0.03/0.21 power density; 0...

Megacystis microcolon intestinal hypoperistalsis syndrome (MMIHS) is a congenital disorder characterized by loss of smooth muscle contraction in the bladder and intestine. To date, three genes are known to be involved in MMIHS pathogenesis: ACTG2, MYH11, and LMOD1. However, for approximately 10% of affected individuals, the genetic cause of the disease is unknown, suggesting that other loci are most likely involved. Here, we report on three MMIHS-affected subjects from two consanguineous families with no variants in the known MMIHS-associated genes...

INTRODUCTION: When performing total hip arthroplasty (THA), it is important to maintain the femoral and acetabular offsets to ensure good joint stability and to restore the function of the hip abductor muscles. In our practice, we mainly use a lateralized stem and hollow out the acetabulum to the quadrilateral plate to accommodate a press-fit polyethylene cup. However, the repercussions of this preparation method, which is driven by the cup's design, are not known. We carried out a retrospective study to assess 1) the changes in the femoral and acetabular offset, 2) the height of the center of rotation, and 3) the repercussions on wear...

We report on a 32-year-old male patient with acute left-hemispheric stroke caused by embolism due to infective endocarditis affected from the HACEK group. Additionally, atypical findings from the transesophageal echocardiography (TEE) which showed fluttering structures belonging to the papillary muscle could be proven as infectious agents with the help of a glucose positron emission tomography (PET) scan. TEE controls showed increasing vegetation involving the mitral valve so that surgery became necessary. The current work reflects, in detail, the emergent clinical course of this young patient, suffering from both an unusual localization and an infrequent cause of endocarditis and focuses on an actual view to the literature...

Mutations of the human valosin-containing protein, p97 (VCP) and Wiskott-Aldrich syndrome protein and SCAR homolog (WASH) complex genes cause motor neuron and cognitive impairment disorders. Here, we analyzed a cohort of German patients with sporadic amyotrophic lateral sclerosis and frontotemporal lobar degeneration comorbidity (ALS/FTD) for VCP and WASH complex gene mutations. Next-generation panel sequencing of VCP, WASH1, FAM21C, CCDC53, SWIP, strumpellin, F-actin capping protein of muscle Z-line alfa 1 (CAPZA1), and CAPZB genes was performed in 43 sporadic ALS/FTD patients...

Loss of neuronal stimulation enhances protein breakdown and reduces protein synthesis, causing rapid muscle mass loss. To elucidate the pathophysiological adaptations that occur in atrophying muscles, we used stable isotope labelling and mass spectrometry to accurately quantify protein expression changes during denervation-induced atrophy after sciatic nerve section in the mouse gastrocnemius muscle (GAST). Additionally, mice were fed a SILAC diet containing (13)C6 lysine for four, seven, or eleven days to calculate relative levels of protein synthesis in denervated and control muscles...

Non-alcoholic fatty liver disease (NAFLD) is associated with hepatic insulin resistance and may result primarily from increased hepatic de novo lipogenesis (PRIM) or secondarily from adipose-tissue lipolysis (SEC). We studied mice with hepatocyte- or adipocyte-specific sterol regulatory-element binding protein-1c (SREBP-1c) overexpression as models of PRIM and SEC. PRIM mice featured increased lipogenic gene expression in liver and adipose tissue. Their selective, liver-specific insulin resistance was associated with increased C18:1-diacylglycerol (DAG) content and protein kinase C (PKC)ε translocation...

BACKGROUND: Socioeconomically deprived children are at increased risk of ill-health associated with sedentary behavior, malnutrition, and helminth infection. The resulting reduced physical fitness, growth retardation, and impaired cognitive abilities may impede children's capacity to pay attention. The present study examines how socioeconomic status (SES), parasitic worm infections, stunting, food insecurity, and physical fitness are associated with selective attention and academic achievement in school-aged children...

Accidents in which a person is run over are often associated with multiple serious injuries. Immediate bleeding control is crucial. Pressure and shear stress at the borders of subcutaneous tissue to the muscle fascia can cause hypoperfusion and the emergence of blood-filled cavities that are associated with a high risk of infection and necrosis, a so-called Morel-Lavallée lesion. Insufficient therapy can lead to local complications and furthermore to live-threatening sepsis.

A prototype of a powered knee orthotic device was developed to determine whether fractional external torque and power support to the knee relieves the biomechanical loads and reduces the muscular demand for a subject performing sit-to-stand movements. With this demonstrator, consisting of the subsystems actuation, kinematics, sensors, and control, all relevant sensor data can be acquired and full control is maintained over actuator parameters. A series-elastic actuator based on a direct current motor provides up to 30 Nm torque to the knee via a hinge joint with an additional sliding degree of freedom...

The means for judging optimal tension during tendon transfers are approximate and not very quantifiable. The purpose of this study was to demonstrate the feasibility of quantitatively assessing muscular mechanical properties intraoperatively using ultrasound elastography (shear wave elastography [SWE]) during extensor indicis proprius (EIP) transfer. We report two cases of EIP transfer for post-traumatic rupture of the extensor pollicis longus muscle. Ultrasound acquisitions measured the elasticity modulus of the EIP muscle at different stages: rest, active extension, active extension against resistance, EIP section, distal passive traction of the tendon, after tendon transfer at rest and then during active extension...

Natriuretic regulation of extracellular fluid volume homeostasis includes suppression of the renin-angiotensin-aldosterone system, pressure natriuresis, and reduced renal nerve activity, actions that concomitantly increase urinary Na+ excretion and lead to increased urine volume. The resulting natriuresis-driven diuretic water loss is assumed to control the extracellular volume. Here, we have demonstrated that urine concentration, and therefore regulation of water conservation, is an important control system for urine formation and extracellular volume homeostasis in mice and humans across various levels of salt intake...

Diabetic cardiomyopathy (DCM) is a disease of heart muscle that remains one of the leading causes of death in diabetic individuals. Shifts in substrate preference resulting in aberrant serum lipid content and enlarged left ventricular wall thickness are well-established characteristics associated with the development of DCM. As underlying mechanisms driving the onset of the DCM remain relatively unclear, this study sought to characterize age-dependent development of left ventricular (LV) wall thickness in diabetic (db/db) mice...

Peripheral artery disease (PAD) is an atherosclerotic vascular disease that affects 200 million worldwide. While PAD primarily affects large arteries, it is also associated with microvascular dysfunction, an exaggerated blood pressure (BP) response to exercise, and high cardiovascular mortality. We hypothesized that fatiguing plantar flexion exercise that evokes claudication elicits a greater reduction in skeletal muscle oxygenation (SmO2) and a higher rise in BP in PAD compared to age-matched healthy subjects, but low-intensity steady state plantar flexion elicits similar responses between groups...

Engineering a small diameter vascular graft with mechanical and biological properties comparable to living tissues remains challenging. Often, current devices lead to thrombosis and unsatisfactory long-term patency as a result of poor blood compatibility and a mismatch between the mechanical properties of the living tissue and the implanted biomaterial. Address-ing all these requirements is essential to produce scaffolds able to survive throughout the life of the patient. For this purpose, we fabricated a novel three-layered vascular graft by combining electrospinning and braiding...

Resting heart rate is a heritable trait, and an increase in heart rate is associated with increased mortality risk. Genome-wide association study analyses have found loci associated with resting heart rate, at the time of our study these loci explained 0.9% of the variation. This study aims to discover new genetic loci associated with heart rate from Exome Chip meta-analyses.Heart rate was measured from either elecrtrocardiograms or pulse recordings. We meta-analysed heart rate association results from 104 452 European-ancestry individuals from 30 cohorts, genotyped using the Exome Chip...
