Background—Body-surface ECG measures (QT dispersion [QTd], QRST integrals) have been used as indices of myocardial repolarization abnormalities with the goal of identifying patients at risk of fatal arrhythmias. The clinical utility of these measures has been questioned. We investigate the complex relationship between epicardial and body-surface potentials in the context of regionally abnormal ...

body weight (bw) is a complex and important economic trait that may benefit from the implementation of marker assisted selection (mas). the objective followed in this study was to identify qtls associated with bw at different ages as distinct traits based on an experimental half-sib cross of japanese quails divergently selected for bw at 4 weeks of age. the body weights at hatch, and as well at...

During communication, we perceive and express emotional information through many different channels, including facial expressions, prosody, body motion, and posture. Although historically the human body has been perceived primarily as a tool for actions, there is now increased understanding that the body is also an important medium for emotional expression. Indeed, research on emotional body la...

The somatotopic organization of the postcentral parietal cortex of the Old World monkey, Macaca fascicularis, was determined with multi-unit microelectrode recordings. The results lead to the following conclusions: 1) There are at least two complete and systematic representations of the contralateral body surface in the cortex of the postcentral gyrus. One representation is contained within Are...

patients and methods in this cross-sectional study, we evaluated all patients referred to a single rheumatology clinic for bone mineral density measurements from 2009 to 2010. all patients who had bone mineral density measurements taken from the hip, lumbar spine, forearm, and whole body were enrolled in the study. standard bone mineral density measurements were performed using a dual energy x-...

IFN-ε is a unique type I IFN whose constitutive expression in lung, brain, small intestine, and reproductive tissues is only partially understood. Our previous observation that posttranscriptional events participate in the regulation of IFN-ε mRNA expression led us to investigate whether the 5' and/or 3' untranslated regions (UTR) have regulatory functions. Surprisingly, we found that full-leng...

This paper presents an approach for determining the presence of people in a still image. The approach starts with the segmentation of skin areas in the images using the YCbCr color space and a set of experimentally defined thresholds. The detected skin areas are then grouped into body part candidate regions. Regions that are too small (typically smaller than 5x5) are discarded. A simple heurist...

RATIONALE AND OBJECTIVE To quantifiably measure the impact of self-instructed radiological anatomy modules on anatomy comprehension, demonstrated by radiology, gross, and written exams. MATERIALS AND METHODS Study guides for independent use that emphasized structural relationships were created for use with two online radiology atlases. A guide was created for each module of the first year med...

BACKGROUND To establish prevalence, risk factors, and impact of work-related musculoskeletal disorders (WMSDs) among farmers in Ireland. METHODS In summer 2009, a questionnaire was appended to the Teagasc (Irish Agricultural and Food Development Authority) National Farm Survey (n = 1,110) to obtain data on the prevalence, risk factors and impact of WMSDs amongst farm operators in Ireland. Dat...

Neuronal circuits in the central nervous system play a critical role in orchestrating the control of glucose and energy homeostasis. Glucose, beside being a nutrient, is also a signal detected by several glucose-sensing units that are located at different anatomical sites and converge to the hypothalamus to cooperate with leptin and insulin in controlling the melanocortin pathway.
