OBJECTIVE To determine which physiological mechanism is responsible for the blood pressure increase during leg crossing at knee-level in the sitting position. METHODS Finger blood pressure was measured with the Finometer in 102 participants (47 men) before and during leg crossing: 24 treated hypertensive patients, 50 diabetic individuals (25 with and 25 without antihypertensive medication) an...

a r t i c l e i n f o This study explored the effects of group norms, intra-group position, and age on the direct and indirect aggressive intentions of 247 children (aged 5.50 to 11.83 years). Participants were assigned to a team, with team norms (aggression vs. helping) and the child's position within the team (prototypical vs. peripheral– prototypical vs. peripheral) manipulated. Results show...

abstract we report a 54-year-old woman with the history of end-stage renal disease (esrd) who was admitted to our hospital because of volume overload. due to long-term use of peripheral veins and arteriovenous fistula (avf) failure, central venous catheterization was the only choice for hemodialysis. she developed right upper extremiti’s pain and paresis during hemodialysis. a posteroanterior c...

Recognition of faces and objects is impaired when illumination direction varies. Three experiments explore whether this impairment can be explained by display changes (Biederman & Bar, 1999), and whether cast shadows help or hinder face recognition. Observers judged whether two sequentially-presented faces, shown with or without cast shadows, were the same person. The faces were illuminated fro...

In the healthy lung, ventilation is distributed heterogeneously due to factors such as anatomical asymmetry and gravity. This ventilation heterogeneity increases pathologically in conditions such as asthma, chronic obstructive lung disease, and cystic fibrosis. In chronic heart failure, lung biopsy demonstrates evidence of peripheral lung fibrosis and small airways narrowing and distortion. We ...

During foveal reaching, the activity of neurons in the macaque medial posterior parietal area V6A is modulated by both gaze and arm direction. In the present work, we dissociated the position of gaze and reaching targets, and studied the neural activity of single V6A cells while the eyes and reaching targets were arranged in different spatial configurations (peripheral and foveal combinations)....

background: multiple sclerosis (ms) is known to affect essentially the central nervous system; however, peripheral nerve involvement, as an additional cause of disability, has been recently noticed. objectives: this study was aimed to perform detailed electrodiagnostic assessments in ms patients to evaluate peripheral nervous system involvement. materials and methods: a total of eighty ms patie...

objective(s):biochemical markers are important for the timely diagnosis and follow-up of ischemic events. most of the markers have been previously studied in the context of cardiac ischemia. however, research on markers of non-cardiac events has been insufficient. therefore, we investigated the relationship between troponin and myoglobin which are commonly used markers of cardiac ischemia, in n...

introduction: neuroblastoma is the most common extracranial solid tumor in children, accounting for 8% to 10% of all childhood cancers. significantly, autologous transplantation appeared to have the largest impact on survival for the high risk subset of patients, such as those with n-myc amplified metastatic disease diagnosed after age 2 years. patients and methods: this study includes high ris...
