background: the aim of this study was to evaluate and compare the clinical and ‎electrocardiographic (ecg) manifestations of benzodiazepines (bzs).‎ methods: in this retrospective study, all bz-poisoned patients hospitalized at loghman ‎hakim hospital between september 2010 and march 2011 were evaluated. patients’ ‎information including age, sex, time elapsed between the ingestion and presentat...

Abstract The electrocardiogram is a very valuable clinical tool which allows to retrieve information about the presence and location of arrhythmic foci as well ischemic scar tissue disorder’s dedicated cardiac conduction system. In presented study timing parameters computed by delineating beat detector for identifying P-Wave, QRS - complex T-Wave are used classify individual beats. From set tot...

The development of electrocardiogram (ECG) wearable devices has increased due to its applications on ambulatory patients. ECG signals provide useful information about the heart behavior, but when daily activities are monitored, motion artifacts introduced producing saturation signal, thus losing information. typical resolution used record is maximum 16-bit, which might not be enough detect low-...

Let M be a compact connected special flat affine manifold without boundary equipped with a Gauduchon metric g and a covariant constant volume form. Let G be either a connected reductive complex linear algebraic group or the real locus of a split real form of a complex reductive group. We prove that a flat principal G–bundle EG over M admits a Hermitian–Einstein structure if and only if EG is po...

When rhythmic firing is elicited in cat spinal motoneurons by long-lasting depolarizing currents, the `threshold' voltage from which each spike arises may appear to be quite constant (Fig . IA, arrow) . If one probes for the threshold during the interspike interval (ISI), however, it is seen to fall well below this level, rising towards it later in the ISL Exceptionally large depolarizing after...

The purpose of this study was to investigate the effects of running drills during an interval training program on biomechanical parameters of running. Thirty recreational runners, divided into 2 groups (control group and experimental group [EG]), were submitted to a 15-week interval training, but only EG performed running drills in the training. The test sessions were accomplished before and af...

bone scanning using the 99mtc-phosphate analogs is an established diagnostic modality and a commonly requested radioisotope examination for a variety of pathologies involving the skeleton, such as osteomyelitis, bony metastases, and occult fractures. the bone scan is one of the most commonly requested procedure in most nuclear medicine department. the images show areas of increased and decrease...

purpose: to evaluate the rate of optical coherence tomography (oct) grid decentration in a routine practice and its effect on thickness measurements methods: topcon spectral domain oct scans from various macular diseases including age related macular degeneration, diabetic macular edema, macular pucker and central serous chorioretinopathy (cscr) were studied in all patients visited during seven...

seventy seven adult large mixed breed dogs of either sex were included in this study. the animals were randomly divided into four groups and received the following drug combinations intramuscularly: group 1 xylazine (0.5 mg/kg) and acepromazine (0.05 mg/kg), group 2 xylazine (0.8 mg/kg) and acepromazine (0.03 mg/kg), group 3 xylazine (0.3 mg/kg) and acepromazine (0.08 mg/kg) and group 4 xylazin...
