Surgical uterine biopsies (SUBs) were obtained by laparotomy from 14 bitches with unexplained infertility whose pregnancy was not confirmed (NCP group) and from 7 bitches that had experienced unexplained pregnancy loss (PL). SUBs were obtained during the luteal phase of the cycle in 16 of 21 bitches. Overall, the biopsied uterine tissues presented obvious(More)
Human polymorphonuclear cells (PMN) were found to adhere to a novel model of blood vessel wall-associated IgG. The internal surfaces of cellulose acetate hollow fibres, of comparable internal diameter to small blood vessels, were coated with normal serum human IgG, heat-aggregated IgG (HAIgG), laminin or fibrinogen. Under conditions of flow mimicking those(More)
The present study was designed to examine changes in vocal intensity following unilateral posteroventral pallidotomy (PVP) in a large sample of speakers with Parkinson's disease (PD) that exhibited a range of hypokinetic dysarthria. Twenty-five persons with PD were recorded using a variety of speech tasks, once prior to and once following PVP. The pre-PVP(More)
Ten hypokinetic parkinsonian patients and ten age- and sex-matched controls were tested, using reaction times with and without a warning signal. The time difference between each was used as a measure of phasic arousal. Both groups' reaction times improved with a warning signal, but there were no differences in reaction-time reduction between the(More)
OBJECTIVE To learn how PD influences verbal description of emotional events. BACKGROUND Individuals with PD exhibit emotional processing deficits. Emotional experience likely involves several dimensions (e.g., valence, arousal, motor activation) subserved by a distributed modular network involving cortical, limbic, basal ganglia, diencephalic, and(More)
Metabolic acidosis was produced in two patients with hypokalemic periodic paralysis by the administration of ammonium chloride over a period of three days. The challenging test of glucose and insulin produced a substantially smaller reduction of both serum potassium concentration and muscle strength than when the patients were tested in normal acid-base(More)
No permanent neurologic deficit results from a transient ischemic attack, but patients with these episodes are at risk of stroke. Successful treatment depends on identifying the source of the problem--the heart, blood, or vessel wall. However, anticoagulants and antiplatelet agglutinating agents will reduce only the incidence of TIA's, not the incidence of(More)
