Fuyong Xing, Xiaoshuang Shi, Zizhao Zhang, JinZheng Cai, Yuanpu Xie, Lin Yang
In order to deal with ambiguous image appearances in cell segmentation, high-level shape modeling has been introduced to delineate cell boundaries. However, shape modeling usually requires sufficient annotated training shapes, which are often labor intensive or unavailable. Meanwhile, when applying the model to different datasets, it is necessary to repeat the tedious annotation process to generate enough training data, and this will significantly limit the applicability of the model. In this paper, we propose to transfer shape modeling learned from an existing but different dataset (e...

PURPOSE: The aim of the study was to compare neuromuscular fatigue induced by repeated sprint running vs cycling. METHODS: Eleven active male participants performed two repeated maximal sprint protocol (5×6 s, 24-s rest periods, 4 sets, 3-min between sets), one in running (treadmill) and one in cycling (cycle ergometer). Neuromuscular function, evaluated before (PRE), 30 s after the first (S1), the second (S2), and the last set (LAST), and 5 min after the last set (POST5), consisted in determining knee extensors maximal voluntary torque (MVC), voluntary activation (VA), single twitch (Tw), high- (Db100) and low- (Db10) frequency torque, and maximal muscle compound action potential (M-wave) amplitude and duration of vastus lateralis...

Inflammatory myopathies are a heterogeneous group of immune-mediated diseases that involve the skeletal muscle as well as many other organs. In addition to a histological diagnosis at muscle biopsy, the clinical phenotypes of inflammatory myopathies can be defined by the presence of various autoantibodies that are originally detected by RNA or protein immunoprecipitation. However, the correlation between histological features and autoantibodies has not been fully elucidated. Immune-mediated necrotizing myopathy (IMNM), which is characterized by significant necrotic and regeneration muscle fibers with minimal or no inflammatory cell infiltration, is associated with the presence of autoantibodies...

Typically, balance training has been used as an intervention paradigm either as static or as reactive balance training. Possible differences in functional outcomes between the two modalities have not been profoundly studied. The objective of the study was to investigate the specificity of neuromuscular adaptations in response to two balance intervention modalities within test and intervention paradigms containing characteristics of both profiles: classical sensorimotor training (SMT) referring to a static ledger pivoting around the ankle joint vs...

Electronic pacemakers have been used in patients with heart rhythm disorders for device-supported pacing. While effective, there are such shortcomings as limited battery life, permanent implantation of catheters, the lack of autonomic neurohumoral responses, and risks of lead dislodging. Here we describe protocols for establishing porcine models of sick sinus syndrome and complete heart block, and the generation of bioartificial pacemaker by delivering a strategically engineered form of hyperpolarization-activated cyclic nucleotide-gated pacemaker channel protein via somatic gene transfer to convert atrial or ventricular muscle cardiomyocytes into nodal-like cells that rhythmically fire action potentials...

Fundamentally, cardiac gene therapy clinical trials have demonstrated that route efficiency is paramount in achieving maximum myocardial expression within safety limits. Gene transfer phenomena are largely influenced by physical transport principles (i.e., pressure, residence time, dispersion trafficking, mechanical resistance) that are independent of therapeutic characteristics. An alternative to intracoronary infusion methods, in an effort to improve efficiency in terms of cardiac specificity, is direct myocardial delivery via surgical injection...

Type 2 diabetes is characterized by triglyceride accumulation and reduced lipid oxidation capacity in skeletal muscle. SIRT1 is a key protein in the regulation of lipid oxidation and its expression is reduced in the skeletal muscle of insulin resistant mice. In this tissue, Sirt1 up-regulates the expression of genes involved in oxidative metabolism and improves mitochondrial function mainly through PPARGC1 deacetylation. Here we examined whether Sirt1 overexpression mediated by adeno-associated viral vectors of serotype 1 (AAV1) specifically in skeletal muscle can counteract the development of insulin resistance induced by a high fat diet in mice...

Langerhans cell histiocytosis (LCH) is a rare histiocytic disorder of unpredictable clinical course and varied modes of presentation. The spectrum of presentation is wide, ranging from isolated eosinophilic granulomas to multiple lesions and diffuse systemic involvement. We present the case of a 52-year-old man, who presented with an 8-week history of worsening otalgia and superficial temporal tenderness attributed to otitis externa within the community and subsequently giant cell arteritis. Computed tomography and magnetic resonance imaging were undertaken due to atypical features, which demonstrated bony destruction within the right greater wing of the sphenoid, squamous part of temporal and mastoid bone, with middle cranial fossa communication...

To better understand the roles played by signaling molecules in the bladder, we established a protocol of intravital imaging of the bladder of mice expressing a Förster/fluorescence resonance energy transfer (FRET) biosensor for extracellular signal-regulated kinase (ERK), which plays critical roles not only in cell growth but also stress responses. With an upright two-photon excitation microscope and a vacuum-stabilized imaging window, cellular ERK activity was visualized in the whole bladder wall, from adventitia to urothelium...

Infectious bursal disease virus (IBDV) causes important economic losses and negatively affects global trade in poultry and poultry products. This study determined the presence of IBDV in primary lymphoid tissues and muscle tissue of infected broilers and the role of vaccination as a mitigation strategy. In the first study, specific-pathogen-free (SPF) broiler chickens were challenged with STC (classical [cIBDV]), Indiana (variant [varIBDV]), rA (very virulent [vvIBDV]), or Ohio (serotype 2, avirulent) IBDV...

Massive rotator cuff tears are difficult to treat surgically due to retraction, degeneration and fraying of the ends of torn tendons, severe fatty infiltration and atrophy of the respective muscles. Procedures developed to close the gap between the rotator cuff and the greater tuberosity of the humerus, such as soft tissue release may be inadequate for large tears. Human or porcine dermal allografts still have uncertain benefits, and tendon transfers seem to be associated with poor outcomes, donor site morbidity and altered mechanics...

In Exp. 1, 56 gestating sows (PIC 1050; 35 d postinsemination) were used in a 30-d trial to determine serum 25(OH)D response to increasing concentrations of dietary vitamin D. Sows were randomly allotted to 1 of 7 dietary D treatments (200, 800, 1,600, 3,200, 6,400, 12,800, or 25,600 IU of added D per kilogram of complete diet) with 8 sows per treatment. Increasing D increased (quadratic; < 0.001) serum 25(OH)D with the response depicted by the prediction equation: serum 25(OH)D, ng/mL = 35.1746 + (0.002353 × dietary D, IU/d) - (0...

Creatine, a key component of muscle energy metabolism, exhibits a chemical exchange saturation transfer (CEST) effect between its amine group and bulk water, which has been exploited to spatially and temporally map creatine changes in skeletal muscle before and after exercise. In addition, exercise leads to an increase in muscle perfusion. In this work, we determined the effects of perfused blood on the CEST effects from creatine in skeletal muscle. Experiments were performed on healthy human subjects (n = 5) on a whole-body Siemens 7T magnetic resonance imaging (MRI) scanner with a 28-channel radiofrequency (RF) coil...

Exoskeleton is a walking assistance device that improves human gait cycle through providing auxiliary force and transferring physical load to the stronger muscles. This device takes the natural state of organ and follows its natural movement. Exoskeleton functions as an auxiliary device to help those with disabilities in hip and knee such as devotees, elderly farmers and agricultural machinery operators who suffer from knee complications. In this research, an exoskeleton designed with two screw jacks at knee and hip joints...

Benzimidazole drugs are used for treatment of trichinellosis, but they have a limited effect against encapsulated larval stages of Trichinella spiralis. Hence, there is a considerable interest in developing new anthelmintic drugs. Our aim is to investigate the possible effect of artemisinin on T. spiralis in in vitro and in vivo studies. T. spiralis worms were isolated from infected mice and transferred to 3 culture media; group I: with no drugs, group II: contained artemisinin and group III: contained mebendazole, then they were subjected to electron microscopic study...

PURPOSE: Concurrent carpal tunnel syndrome and pronator syndrome are rarely considered and the proximal compression sites are easily overlooked. We retrospectively studied 21 concurrent cases in our series from 2009 to 2015 and report the results. PATIENTS AND METHODS: The typical symptoms were pain, tingling, and numbness of the radial 3½ digits. If paresthesia involved the thenar eminence and proximal forearm pain was noted in cases of carpal tunnel syndrome, carpal tunnel syndrome combined with pronator syndrome was considered...
