Although lifting the heels has frequently been observed during balance recovery, the function of this movement has generally been overlooked. The present study aimed to investigate the functional role of heel lifting during regaining balance from a perturbed state. Computer simulation was employed to objectively examine the effect of allowing/constraining heel lifting on balance performance. The human model consisted of 3 rigid body segments connected by frictionless joints. Movements were driven by joint torques depending on current joint angle, angular velocity, and activation level...

BACKGROUND: Type 2 diabetes is a chronic disorder that requires lifelong treatment. We aimed to assess whether intensive weight management within routine primary care would achieve remission of type 2 diabetes. METHODS: We did this open-label, cluster-randomised trial (DiRECT) at 49 primary care practices in Scotland and the Tyneside region of England. Practices were randomly assigned (1:1), via a computer-generated list, to provide either a weight management programme (intervention) or best-practice care by guidelines (control), with stratification for study site (Tyneside or Scotland) and practice list size (>5700 or ≤5700)...

BACKGROUND: Atrial fibrillatory cycle length has been considered one of the indices of atrial electrical remodelling during atrial fibrillation (AF), which can be assessed from surface ECG by computer-assisted calculation of atrial fibrillatory rate (AFR). Horses have been suggested as a bona fide model for AF studies since horses too, develop lone AF, however data on AF characteristics in horses are extremely sparse and non-invasive characterization of AF complexity using surface ECG processing has not been reported...

We present a case of prenatal diagnosis of a mediastinal cyst by ultrasound, confirmed during infancy through computed tomography (CT) and magnetic resonance imaging (MRI). A 6-month-old male infant was admitted to the hospital. A mid-mediastinal cyst was detected through a province-wide fetal ultrasonography screening program. During the infancy stage, the CT scan and the MRI confirmed the finding of a mediastinal cyst. Based on the findings on prenatal ultrasonography and postnatal imaging studies (CT, MRI), a benign mediastinal cyst was suspected...

Computational annotation of textual information has taken on an important role in knowledge extraction from the biomedical literature, since most of the relevant information from scientific findings is still maintained in text format. In this endeavour, annotation tools can assist in the identification of biomedical concepts and their relationships, providing faster reading and curation processes, with reduced costs. However, the separate usage of distinct annotation systems results in highly heterogeneous data, as it is difficult to efficiently combine and exchange this valuable asset...

BACKGROUND: Medial collateral ligament (MCL) reconstruction of the elbow mandates precise characterization of where the centerline of elbow rotation projects onto the medial epicondyle (ME). A muscle-splitting approach allows the flexor-pronator muscles to remain attached to the ME and facilitates visualization of the MCL remnant, the sublime tubercle, and the ulnohumeral joint line. Knowledge of where the centerline of rotation intersects the ME relative to the ulnohumeral joint line may assist the surgeon during placement of the proximal drill hole...

The catalytic cycle of a new derivative of ebselen, 1, was elucidated via three steps by the density functional theory and solvent-assisted proton exchange procedure involving indirect proton exchange through a hydrogen-bonded transfer network. Different behaviors of the aromatic and aliphatic thiols were investigated in the reduction of selenoxide (step 2→3) and selenurane (step 3→1) based on their nucleophilicity. The reduction of selenoxide in the presence of thiophenol (ΔG≠=15.9 kcal.mol-1) is faster than methanethiol (ΔG≠=29...

Histoplasmosis is a common endemic mycosis in North, Central, and South America, but Korea is not known as an endemic area. We treated an immunocompetent Korean patient who had histoplasmosis. A 65-year-old Korean man presented with multiple pulmonary clumps of tiny nodules in the both lungs. He had been diagnosed 40 years earlier with pulmonary tuberculosis (TB) and a fungus ball had been diagnosed 4 years earlier. He denied any history of overseas travel. The patient visited our hospital with dyspnea, blood-tinged sputum, and weight loss, which had appeared 2 months earlier...

Progestins are utilized as a component of human contraceptives, and enter the environment via wastewater treatment plant effluent. Certain progestins activate fish androgen receptors and cause decreases in fecundity and masculinization of females. In this study, a nest acquisition assay and computer assisted sperm analysis (CASA) was used to examine the effects of levonorgestrel (LNG) on male fathead minnow (Pimephales promelas) reproductive fitness. Males were exposed to 0, 10, or 100ng/L LNG for 14d. Combinations of a control male and a male from one of the treatments were placed into a competitive nesting assay, and time each male spent holding the nest and time spent exhibiting aggressive behaviors were analyzed at 48hrs post-exposure...
