An Eye-Tracking System based on Inner Corner-Pupil Center Vector and Deep Neural Network.

The human eye is a vital sensory organ that provides us with visual information about the world around us. It can also convey such information as our emotional state to people with whom we interact. In technology, eye tracking has become a hot research topic recently, and a growing number of eye-tracking devices have been widely applied in fields such as psychology, medicine, education, and virtual reality.

Accuracy of paramedic diagnosis of stroke.

Background And Purpose: Accurate prehospital diagnosis of acute stroke may lead to fewer delays in hospital presentation. In addition, prehospital personnel soon may be administering therapies to patients with presumed stroke. We sought to determine the sensitivity and positive predictive value (PPV) of paramedic diagnosis of stroke in Mobile, Alabama, and to evaluate the impact of an educational program on paramedic diagnostic capability.

Intravenous t-PA for acute ischemic stroke: therapeutic yield of a stroke code system.

Subsequent to publication of the NINDS t-PA Stroke Study results, we sought to determine the proportion of patients eligible for and receiving intravenous tissue plasminogen activator (t-PA) at an active acute stroke treatment center. Over a 12-month period there were 185 stroke code activations. Of these, 134 involved patients with ischemic stroke, and 48 of these (36%) were potentially eligible for treatment with t-PA by the time criterion (i.

Recovery of virus from the liver of children with fatal dengue: reflections on the pathogenesis of the disease and its possible analogy with that of yellow fever.

Dengue viruses types 2 or 3 were recovered from the liver of 5 out of 17 children who were suspected to have died of dengue. Among the 5 children with liver isolates, virus was also recovered from the heart blood, spleen and midbrain of one and from the spleen of another. Attention is drawn to the many similarities in the clinical manifestations of yellow fever and severe dengue, their indistinguishable liver lesions and the close relationship of the viruses themselves.
