Fifty four patients with idiopathic Parkinson's disease receiving levodopa therapy were studied. Thirty three of these patients displayed peak-dose dyskinesia. Neither the duration of Parkinson's disease nor the duration of levodopa therapy discriminated between patients with and patients without peak-dose dyskinesia. Consequently, these criteria could not determine whether the first appearance...

We studied the cortical processing of spatial stimuli by magnetoencephalographic (MEG) measurements using broadband noise bursts presented from eight sound source directions in the horizontal plane. The stimuli were individually created for each subject by using three-dimensional (3D) sound techniques. The subjects carried out a behavioral task where their accuracy for localizing the 3D stimuli...

Recurrent wildWres constitute a major selecting force in shaping the structure of plant communities. At the regional scale, Wre favours phenotypic and phylogenetic clustering in Mediterranean woody plant communities. Nevertheless, the incidence of Wre within a Wre-prone region may present strong variations at the local, landscape scale. This study tests the prediction that woody communities on ...

OBJECTIVE To study face and emotion recognition in children with mostly expressive specific language impairment (SLI-E). SUBJECTS AND METHODS A test movie to study perception and recognition of faces and mimic-gestural expression was applied to 24 children diagnosed as suffering from SLI-E and an age-matched control group of normally developing children. RESULTS Compared to a normal control...

According to past reports, H-2Ma0/0 mice express a single major histocompatiblity complex class II molecule, A(b), heavily loaded with a single peptide derived from the invariant chain, CLIP. Despite the highly restricted diversity of the class II:peptide complexes expressed on thymic stromal cells in the mutant animals, a large and diverse population of CD4+ T cells is positively selected. How...

TEis problem has been of only moderate interest to research workers, and publications and monographs on the subject have been sporadic, though a few well-known names must be cited here (Leber, 1865a, b, 1872, 1903; Magitot, 1908, 1947; Behr, 1935; Wolff, 1939, 1940, 1948). The findings being very diverse, it seemed appropriate to try to find experimentally the normal vascular anatomy of the opt...

An 84-year-old woman underwent hysterectomy due to a friable endometrial mass infiltrating almost half way through the myometrial wall. The tumor consisted of papillary structures with thin fibrovascular cores covered by several layers of pleomorphic cells. The deeply located neoplastic cells were ovoid with a pale eosinophilic cytoplasm resembling urothelial cells. A diagnosis of papillary squ...

Hydrogenated microcrystalline silicon (μc-Si:H) layers about 500 nm thick were deposited in the same run on flat and rough substrates (rms = 60 nm) of various chemical nature. This study reveals that the spatial distribution of the microcrystalline/amorphous phases within the layer depends on the substrate’s topography. The influence of the chemical nature of the substrate is shown to be prepon...

Proactive interference was assessed with a variant of the process-dissociation procedure, which separates effects of habit (accessibility bias) and recollection (discriminability). In three cued-recall experiments, proactive interference was shown to be an effect of bias rather than an effect on actual remembering. Divided attention, age, and study duration selectively influenced the recollecti...

Italy represents an unexpected and in some ways paradoxical outcome in terms of fertility control: one of the lowest birth rates in the world seems to have been accomplished through the preponderant use of “traditional” methods. Compared to other countries, there has been a reluctance to abandon coitus interruptus. In France in 1994, 84% of women used IUDs or the pill, compared to 42% in Italy ...
