Increased heart rate after exercise facilitates the processing of fearful but not disgusted faces.

Embodied theories of emotion assume that emotional processing is grounded in bodily and affective processes. Accordingly, the perception of an emotion re-enacts congruent sensory and affective states; and conversely, bodily states congruent with a specific emotion facilitate emotional processing. This study tests whether the ability to process facial expressions (faces having a neutral expression, expressing fear, or disgust) can be influenced by making the participants' body state congruent with the expressed emotion (e.g., high heart rate in the case of faces expressing fear). We designed a task requiring participants to categorize pictures of male and female faces that either had a neutral expression (neutral), or expressed emotions whose linkage with high heart rate is strong (fear) or significantly weaker or absent (disgust). Critically, participants were tested in two conditions: with experimentally induced high heart rate (Exercise) and with normal heart rate (Normal). Participants processed fearful faces (but not disgusted or neutral faces) faster when they were in the Exercise condition than in the Normal condition. These results support the idea that an emotionally congruent body state facilitates the automatic processing of emotionally-charged stimuli and this effect is emotion-specific rather than due to generic factors such as arousal.

The occurrence and pathogenicity of Serratospiculum tendo (Nematoda: Diplotriaenoidea) in birds of prey from southern Italy.

The air sacs of free-ranging birds of prey (n= 652) from southern Italy, including 11 species of Accipitriformes and six of Falconiforms, were examined for infections with Serratospiculum tendo (Nematoda: Diplotriaenoidea). Of the 17 species of birds examined, 25 of 31 (80.6%) peregrine falcons (Falco peregrinus) from Calabria Region and a single northern goshawk (Accipiter gentilis) from Campania Region were infected with S. tendo, suggesting a strong host specificity for the peregrine falcon. The northern goshawk and 18 of 25 infected peregrine falcons showed cachexia and all infected birds had bone fractures. At gross examination, air sacculitis and pneumonia were the most common lesions in infected birds. Microscopically, the air-sac walls showed thickening of the smooth muscle cells, resulting in a papillary appearance, along with hyperplasia of the mesothelium and epithelium, and foci of plasma cell infiltration and macrophages associated with several embryonated eggs and adult parasites. Extensive areas of inflammation were found in the lungs, characterized by lymphocytes, macrophages and fibroblasts surrounding embryonated eggs. The northern goshawk also had detachment of the dextral lung with several necrotic foci. In this case, the death of the bird was directly attributed to S. tendo infection. Lesions and pathological changes observed here suggest that S. tendo can cause disease.

Word reading and picture naming in Italian.

Results from two separate norming studies of lexical access in Italian were merged, permitting a comparison of word-reading and picture-naming latencies and the factors that predict each one for an overlapping subsample of 128 common nouns. Factor analysis of shared lexical predictors yielded four latent variables: a frequency factor, a semantic factor, a length factor, and a final factor dominated by frication on the initial phoneme. Age of acquisition (AoA) loaded highly on the first two factors, suggesting that it can be split into separate sources of variance. Regression analyses using factor scores as predictors showed that word reading and picture naming are both influenced by the frequency/AoA factor. The semantics/AoA factor influenced only picture naming, whereas the length and frication factors influenced only word reading. Generalizability of these results to other languages is discussed, including potential effects of cross-language differences in orthographic transparency.

Combined cyclosporin A-steroid-MTX treatment in endogenous non-infectious uveitis.

Thirty-two patients with endogenous uveitis resistant to treatment with high doses of cortisone and other immunosuppressive agents were treated with cyclosporin A (at an initial dose of 5 mg/kg/die, subsequently modified according to individual clinical response), fluocortolone and methotrexate. Total and lasting disease remission was obtained in all patients, together with the recovery of normal visual acuity in 20 cases and its significant improvement in the remaining 12. Furthermore, in all patients the total disappearance of all ocular inflammatory activity was observed and maintained for a period of 10.87 +/- 5.31 (6-18) months. No signs of renal or hepatic toxicity were observed in any of the patients. A form of hirsutism appeared in only two cases.

Intraocular pressure changes in secondary positions of gaze in normal subjects and in restrictive ocular motility disorders.

One hundred normal Caucasian eyes and 29 eyes with restrictive disorders of ocular motility were studied in order to delineate intraocular pressure changes in secondary positions of gaze. Applanation tonometry was performed in the primary position and at an angle of 22 degrees. In patients with restrictive syndromes the changes of intraocular pressure in the secondary positions of gaze were significantly higher (p less than 0.0001) than in normal subjects. The range of variation in normal subjects was 0, +3 mmHg for supraduction and -3, +1 mmHg for abduction. Patients with restrictive syndromes showed changes between +1 and +15 mmHg for supraduction and between +3 and +10 mmHg for abduction. Results obtained in the two groups showed the existence of false negatives. This test is thus a practical and useful diagnostic tool, but its results must be evaluated cautiously.

Divergence pseudoparalysis: a case report.

Divergence paralysis is a clinical syndrome that is characterized by esotropia and diplopia at distance fixation and fusion at near fixation. This syndrome is thought to result from a lesion in the brain stem, probably in the midbrain or in the pontine region. This paper reports a case in which ocular motility disturbances, simulating divergence paralysis, were caused by a bilateral and symmetrical restrictive syndrome involving the medial rectus muscles.

Diabetic retinopathy and colour discrimination under various illuminants.

25 patients suffering from diabetic retinopathy, examined with the aid of 100-hue test, show an acquired tritan-like deficiency. Colour discrimination impairment is found to run parallel to visual acuity deterioration. When tested under illumination produced by an Hg source, relatively poor of energy in the short wavelength range, an improvement in colour discrimination (decrease in total score) compared to C illumination is found.
