Development of cerebral inhibitory processes among individuals with Down syndrome (DS) may be delayed at an early age. In support of this hypothesis, sensory-evoked potentials (EPs) and event-related brain potentials (ERPs) have previously delineated altered habituation to stimuli among infants with DS. The purpose of the current study was to provide(More)
AIMS To evaluate the potential for the direct transmission of tuberculosis from possums to alpacas, and vice versa. METHODS A field study was conducted on an alpaca farm in Northland, New Zealand on 7 January 1999. Observations were recorded on the interaction of one group of male alpacas with a simulated dead possum, one male and one female alpaca group(More)
According to the two currently most popular biological hypotheses, schizophrenic symptoms result from a hyperactivity in dopaminergic neurotransmission or from a hypoactivity in GABAergic neurotransmission. Since diazepam is known to reduce dopamine release and to potentiate GABA, the possible beneficial effects of diazepam were tested in ten hospitalized(More)
Two hundred and forty-two patients with acute schizophrenia were enrolled in a double-blind, comparative, dose-finding study of a novel antipsychotic, remoxipride. Remoxipride was evaluated in a low (30 to 90 mg), medium (120 to 240 mg) and a high (300 to 600 mg) dose range and compared with a haloperidol (15 to 45 mg), which was administered to a similar(More)
The DBA/2 strain of mice have genetically induced vestibular dysfunction that presents grossly at an early age as circling behavior and abnormal righting reflexes. The vestibular morphology of this strain has not previously been examined. DBA/2 mice of different ages that showed circling behavior were sacrificed and then had their inner ears immediately(More)
The advent of magnetic resonance imaging (MRI) has improved imaging of the Achilles tendon. Various pathologic conditions of the Achilles tendon and their MRI characteristics are described. The superior resolution of the tendon provided by MRI can aid in the diagnosis of Achilles tendon disorders, which include complete or partial rupture of the tendon as(More)
