Chest X-ray (CXR) is a low-cost medical imaging technique. It common procedure for the identification of many respiratory diseases compared to MRI, CT, and PET scans. This paper presents use generative adversarial networks (GAN) perform task lung segmentation on given CXR. GANs are popular generate realistic data by learning mapping from one domain another. In our work, generator GAN trained segmented mask input The discriminator distinguishes between ground truth generated mask, updates...
Abstract U-Net is a widely adopted neural network in the domain of medical image segmentation. Despite its quick embracement by imaging community, performance suffers on complicated datasets. The problem can be ascribed to simple feature extracting blocks: encoder/decoder, and semantic gap between encoder decoder. Variants (such as R2U-Net) have been proposed address blocks making deeper, but it does not deal with problem. On other hand, another variant UNET++ deals introducing dense skip...
BackgroundIn patients with pulmonary hypertension (PH), ascertaining raised vascular resistance as a cause is clinical objective, for which various Doppler-based measurements have been proposed, but modest accuracy. We hypothesize that acceleration time (PAcT) and the ratio of PAcT/peak artery systolic pressure (PASP) reflect better extent resistance, compared other available methods, can differentiate accurately between pre- post-capillary PH.
Non-adherence to guidelines and preventive measures is a major challenge, particularly so obtain long-term adherence lifestyle changes recommended medication. The objective was investigate if pictorial information regarding subclinical carotid atherosclerosis provided individuals physicians gave sustained effects on cardiovascular risk beyond the previously reported effect after 1 year up 3 years.A Prospective Randomized Open Blinded End-point (PROBE) trial. Within CVD prevention program in...
Abstract The central nervous system (CNS) controls skeletal muscles by the recruitment of motor units (MUs). Understanding MU function is critical in diagnosis neuromuscular diseases, exercise physiology and sports, rehabilitation medicine. Recording analyzing MUs’ electrical depolarization basis for state-of-the-art methods. Ultrafast ultrasound a method that has potential to study MUs because depolarizations consequent mechanical twitches. In this study, we evaluate if single their...
The central nervous system coordinates movement through forces generated by motor units (MUs) in skeletal muscles. To analyze MUs function is essential sports, rehabilitation medicine applications, and neuromuscular diagnostics. their are studied using electromyography. Typically, these methods study only a small muscle volume (1 mm <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">3</sup> ) or superficial (<1 cm) of the muscle. Here we introduce...
Abstract Background fibromyalgia is a relatively common condition with widespread pain and pressure allodynia, but unknown aetiology. For decades, the association between motor control strategies chronic has been topic for debate. One long held functional neuromuscular mechanism differential activation regions within single muscle. The aim of this study was to investigate differences in control, i.e. activation, myalgic trapezius patients healthy controls. Methods 27 30 controls performed 3...
A surface electromyogram (sEMG) contains information about physiological and morphological characteristics of the active muscle its neural strategies. Because electrodes are situated on skin above muscle, sEMG is an easily obtainable source information. However, different combinations can lead to similar signals recordings contain noise other artefacts. Therefore, many signal processing methods have been developed applied allow insight into neuromuscular physiology. This paper gives overview...

The ability of fingers to rapidly rewarm following cold exposure is a possible indicator injury protection. We categorized the post-cooling hand-rewarming responses men before and after participation in 15 mo military training environment northern Sweden determine: 1) if initial rewarming category was related occurrence local during training; 2) affected subsequent responses.Immersion dominant hand 10 degrees C water for min performed pre-training on 77 men. Of those, 45 were available...
We aimed to explore the prevalence of atherosclerosis by using multi-view ultrasound examination carotid arteries and its association with clinical risk factors in a middle-aged population at low intermediate cardiovascular disease (CVD). Carotid vascular was performed 3532 participants VIPVIZA trial. Mean maximal intima media thickness (cIMT) prespecified angles plaque presence were examined on left right side. Associations between CVD variables quantified partial least squares (PLS)...
In this study, the aim was to compare performance of four spatiotemporal decomposition algorithms (stICA, stJADE, stSOBI, and sPCA) parameters for identifying single motor units in human skeletal muscle under voluntary isometric contractions ultrafast ultrasound image sequences as an extension a previous study. The quantified using two measures: (1) similarity components' temporal characteristics against gold standard needle electromyography recordings (2) agreement detected sets components...
Abstract Aim: To examine the occurrence of repeated differential activation between heads biceps brachii muscle and its relation to fatigue prevention during a submaximal contraction. Methods: Thirty‐nine subjects carried out an isometric contraction elbow flexion at 25% maximal voluntary (MVC) until exhaustion. A grid 13 by 10 electrodes was used record surface electromyographic signals from both brachii. The root‐mean‐square recorded located medially laterally analyse differences....
During a voluntary contraction, motor units (MUs) fire train of action potentials, causing summation the twitch forces, resulting in fused or unfused tetanus. Twitches have been important studying whole-muscle contractile properties and differentiation between MU types. However, there are still knowledge gaps concerning force generation mechanisms. Current methods rely on spike-triggered averaging technique, which cannot track changes successive twitches' response to individual neural...
Skeletal muscles are functionally regulated by populations of so-called motor units (MUs). An MU comprises a bundle muscle fibers controlled neuron from the spinal cord. Current methods to diagnose neuromuscular diseases and monitor rehabilitation, study sports sciences rely on recording analyzing bio-electric activity MUs. However, these provide information limited part muscle. Ultrasound imaging provides large It has recently been shown that ultrafast ultrasound can be used record analyze...
