Histotripsy is a non-invasive, focused ultrasound lesioning technique that can ablate precise volumes of soft tissue using a novel mechanical fractionation mechanism. Previous research suggests that magnetic resonance imaging (MRI) may be a sensitive image-based feedback mechanism for histotripsy. However, there are insufficient data to form some unified understanding of the response of the MR contrast mechanisms in tissues to histotripsy. In this paper, we investigate the response of the MR contrast parameters R1, R2, and the apparent diffusion coefficient (ADC) to various treatment levels of histotripsy in in-vitro porcine liver, kidney, muscle, and blood clot as well in formulations of bovine red blood cells suspended in agar gel...

The failure of mitral valve repair procedures revealed in the outcomes of the recent randomized studies is suggesting the necessity for a better understanding of the biomechanical mechanisms underlying the failure of the surgical approaches. Use of biomechanical modelling and finite element analysis (FEA) in cardiovascular research is an important aid in this context. In our group we developed a biomechanical model taking into account all the component of the mitral valve functional unit including the valve leaflets, the annulus, the papillary muscles, the chordae tendinea and the ventricular geometry...

Ischemic mitral regurgitation (IMR) is a complex disorder occurring after a myocardial infarction and affecting both the mitral valvular and subvalvular apparati. Several abnormalities can be detected in IMR as annular dilatation, leaflet tethering with impaired coaptation and papillary muscle (PM) displacement along a posterior, apical or lateral vectors. Treatments available include, beside myocardial revascularization, mitral-valve repair or chordal-sparing replacement. Repair is normally achieved downsizing the mitral valve annulus with a rigid or semirigid ring...

In recent years, much research has been suggested and examined for the development of tissue engineering scaffolds to promote cellular behaviors. In our study, RGD peptide and graphene oxide (GO) co-functionalized poly(lactide-co-glycolide, PLGA) (RGD-GO-PLGA) nanofiber mats were fabricated via electrospinning, and their physicochemical and thermal properties were characterized to explore their potential as biofunctional scaffolds for vascular tissue engineering. Scanning electron microscopy images revealed that the RGD-GO-PLGA nanofiber mats were readily fabricated and composed of random-oriented electrospun nanofibers with average diameter of 558 nm...

Audrey Loumaye, Jean-Paul Thissen
Cachexia is a complex multifactorial syndrome, characterized by loss of skeletal muscle and fat mass, which affects the majority of advanced cancer patients and is associated with poor prognosis. Interestingly, reversing muscle loss in animal models of cancer cachexia leads to prolong survival. Therefore, detecting cachexia and maintaining muscle mass represent a major goal in the care of cancer patients. However, early diagnosis of cancer cachexia is currently limited for several reasons. Indeed, cachexia development is variable according to tumor and host characteristics...

Filamin B (FLNB) is a large dimeric actin-binding protein which crosslinks actin cytoskeleton filaments into a dynamic structure. Up to present, pathogenic mutations in FLNB are solely found to cause skeletal deformities, indicating the important role of FLNB in skeletal development. FLNB-related disorders are classified as spondylocarpotarsal synostosis (SCT), Larsen syndrome (LS), atelosteogenesis (AO), boomerang dysplasia (BD), and isolated congenital talipes equinovarus, presenting with scoliosis, short-limbed dwarfism, clubfoot, joint dislocation and other unique skeletal abnormalities...

Although sleep and sleep disorders have been studied for centuries, it was the development of sophisticated tools to monitor eye movements, brain waves, and muscle tone in the mid-20th century that led to modern sleep research. These tools allowed neuroscientists to distinguish between different "states" or "phases" of sleep, and to relate these findings to sleep disorders. This review chronicles the groundbreaking work of the pioneers in this field, and the impact their findings have had on patients today.

Werner syndrome (WS) is a rare inheritable progeroid syndrome caused by a mutation in the WRN gene. Although WS has been described as a characteristic appearance of very slender extremities with a stocky trunk, few studies have investigated the loss of muscle mass, fat mass distribution (body composition), and mobility according to age and sex. Therefore, the aim of this study was to precisely describe the body composition in WS. Nine Japanese patients with WS (four males and five females; mean age 48±8.8 years) were recruited...

Biomarker discovery and validation is a critical aim of the medical and scientific community. Research into exercise and diet-related biomarkers aims to improve health, performance, and recovery in military personnel, athletes, and lay-persons. Exercise physiology research has identified individual biomarkers for assessing health, performance, and recovery during exercise training. However, there are few recommendations for biomarker panels for tracking changes in individuals participating in physical activity and exercise training programs...

BACKGROUND: Endomyocardial biopsy (EMB) has been defined as the gold standard method for surveillance of rejection after heart transplantation, and it has also been used in the diagnosis of myocarditis and the unknown causes of cardiomyopathies. The procedure, however, is not free from complications. Access through the jugular vein or the femoral vein is the standard approach. In this study, we performed biopsies by using a long, curved sheath and evaluated the rate of complications with this technique...

In molluscs, muscle contraction is triggered by a direct binding of Ca(2+) to myosin. The myosin essential light chain (MELC) provides the Ca(2+) binding site and is of importance for motor function and regulation. In this study, the complete cDNA sequence of MELC gene of the Pacific oyster, Crassostrea gigas, was obtained, and the expression profiles were performed in different tissues and different embryo-larval development stages. The results showed that the full length of C. gigas MELC (CgMELC) cDNA was 659 bp, containing a 5'-untranslated region of 73 bp, a 3'-untranslated region of 112 bp...

Chronic pancreatitis is a chronic inflammatory disease of the pancreas characterised by irreversible morphological change and typically causing pain and/or permanent loss of function. This progressive, irreversible disease results in destruction of healthy pancreatic tissue and the development of fibrous scar tissue. Gradual loss of exocrine and endocrine function follows, along with clinical manifestations such as steatorrhoea, abdominal pain and diabetes. Nutrition in chronic pancreatitis has been described as a problem area and, until recently, there was little research on the topic...

Botulinum toxin (BT) has long been infamous in food safety and biological warfare. In the early 1970s, Alan B Scott of San Francisco invented its therapeutic use originally in extraocular eye muscles to treat strabismus using a therapeutic BT type A preparation provided by Edward J Schantz and Eric A Johnson. Subsequently a large number of medical indications based on motor and glandular hyperactivity and-most recently-chronic migraine are now treated by BT therapy. BT's highly specific and elaborate mechanism of action represents a completely novel therapeutic principle which will have consequences far beyond existing indications...
