Symmetry, averageness, and feature size in the facial attractiveness of women
2004
International audience; Female facial attractiveness was investigated by comparing the ratings made by male judges with the metric characteristics of female faces. Three kinds of facial characteristics were considered: facial symmetry, averageness, and size of individual features. The results suggested that female face attractiveness is greater when the face is symmetrical, is close to the average, and has certain features (e.g., large eyes, prominent cheekbones, thick lips, thin eyebrows, and a small nose and chin). Nevertheless, the detrimental effect of asymmetry appears to result solely from the fact that an asymmetrical face is a face that deviates from the norm. In addition, a factor …
Asymptomatic Leishmania infantum/chagasi infection in blood donors of western Sicily.
2007
The purpose of this study was to evaluate whether the risk of transfusion-transmitted visceral leishmaniasis was present in an area of western Sicily where the incidence of the disease is higher than the regional average. From May to December 2005, 1449 blood donors from Agrigento district (Sicily, Italy) were screened for the presence of anti-Leishmania antibodies by an indirect immunofluorescent antibody test (IFAT). Blood samples from IFAT-positive donors were examined by PCR to detect Leishmania DNA. Anti-Leishmania antibodies were found in 11 (0.75%) cases, among which Leishmania DNA was detected from four (36.4%). Particular techniques to inactivate different pathogens would be consid…
Balantidiasis in Aymara children from the northern Bolivian Altiplano.
1998
Balantidium coli infection was coprologically studied in 2,124 Aymara children 5-19 years of age from the schools of 22 communities of the northern Bolivian Altiplano over a five-year period. Infection with B. coli was found in 11 of the communities surveyed, with prevalences of 1.0-5.3% (overall prevalence=1.2%). The prevalences observed are some of the highest reported and did not differ significantly among the various age groups or between boys and girls. These prevalences, the apparent absence of symptoms or signs of illness due to this parasite in the schoolchildren surveyed at the time of stool sampling, and the consistency of stool samples of the infected students suggest that they a…
Clinical evaluation of pancreatitis-associated protein as a serum marker of hepatocellular carcinoma: Comparison with α-fetoprotein
1998
This study evaluated the significance of serum pancreatitis-associated protein (PAP) assay, as a marker of hepatocellular carcinoma (HCC), in comparison and combined with α-fetoprotein (AFP) assay. Sixty-five patients with HCC, 59 with liver cirrhosis (LC) and 68 asymptomatic controls (C) were studied. PAP and AFP values significantly increased from C to LC and HCC group (p < 0.0001). The area under receiver-operating characteristic (ROC) curve for the two markers was not statistically different. At 100% specificity, ROC analysis gave a cut-off level for AFP of 166 IU/l with 40% sensitivity, and a cut-off level of 240 µg/l for PAP with 23% sensitivity. Diagnostic accuracy of combined AFP…
Efficacy of mometasone furoate microemulsion in the treatment of erosive-ulcerative oral lichen planus: pilot study
2004
Background: Oral lichen planus (OLP) is a frequent immunological chronic disease, having different clinical forms: asymptomatic and symptomatic. Symptomatic OLP has been palliated with topical corticosteroids with different levels of efficacy and safety. The purpose of this pilot phase II clinical trial was to determine the efficacy of mometasone furoate microemulsion upon the symptoms and signs of erosive-ulcerative OLP. Methods: Forty-nine patients with clinical and histologically confirmed erosive-ulcerative OLP were enrolled in this study (36 women and 13 men). Their average age was 56.4 years (from 28 to 78). The treatment consisted of 0.1% mometasone furoate microemulsion mouthwash …
Oligophrenin 1 mutations frequently cause X-linked mental retardation with cerebellar hypoplasia
2005
Background: Mutations of oligophrenin 1, one of the first genes identified in nonspecific X-linked mental retardation (MRX), have been described in patients with moderate to severe cognitive impairment and predominant cerebellar hypoplasia, in the vermis. Objective: To further delineate the phenotypic and mutational spectrum of the syndrome, by screening oligophrenin 1 in two cohorts of male patients with mental retardation (MR) with or without known posterior fossa anomalies. Methods: Clinical examination, cognitive testing, MRI studies, and mutational analysis (denaturing gradient gel electrophoresis and direct sequencing) on blood lymphocytes were performed in 213 unrelated affected indi…
Asymmetry in the human primary somatosensory cortex and handedness.
2003
Brain asymmetry is a phenomenon well known for handedness and language specialization and has also been studied in motor cortex. Less is known about hemispheric asymmetries in the somatosensory cortex. In the present study, we systematically investigated the representation of somatosensory function analyzing early subcortical and cortical somatosensory-evoked potentials (SEP) after electrical stimulation of the right and left median nerve. In 16 subjects, we compared thresholds, the peripheral neurogram at Erb point, and, using MRI-based EEG source analysis, the P14 brainstem component as well as N20 and P22, the earliest cortical responses from the primary sensorimotor cortex. Handedness w…
Linear and Volumetric Mandibular Asymmetries in Adult Patients With Different Skeletal Classes and Vertical Patterns: A Cone-Beam Computed Tomography…
2018
AbstractThis study aimed to quantify the height of the mandibular condyle and ramus, condylar volume, and the asymmetry index in adult patients of different sex, skeletal class and vertical pattern using Cone-Beam Computed Tomography (CBCT), and to determine whether there were differences between these groups. The study used CBCT scans of 159 patients with a mean age of 32.32 ± 8.31 years. InVivoDental® software was used to perform both linear (condylar, ramal, and total height) and condylar volume measurements. Linear and volumetric asymmetries were calculated. There were not significant differences between right and left sides. The mean value obtained for condyle height was 7.27 mm, ramus…
Computed tomography coronary angiography in asymptomatic patients
2011
This study assessed the accuracy of computed tomography coronary angiography (CT-CA) for detecting significant coronary artery disease (CAD; a parts per thousand yen50% lumen reduction) in intermediate/high-risk asymptomatic patients. A total of 183 consecutive asymptomatic individuals (92 men; mean age 54 +/- 11 years) with more than one major risk factor (obesity, hypertension, diabetes, hypercholesterolaemia, family history, smoking) and an inconclusive or nonfeasible noninvasive stress test result (stress electrocardiography, stress echocardiography, nuclear stress scintigraphy) underwent CT-CA in an outpatient setting. All patients underwent conventional coronary angiography (CAG) with…
Structural hemispheric asymmetries underlie verbal Stroop performance
2017
Performance on tasks involving cognitive control such as the Stroop task is often associated with left lateralized brain activations. Based on this neuro-functional evidence, we tested whether leftward structural grey matter asymmetries would also predict inter-individual differences in combatting Stroop interference. To check for the specificity of the results, both a verbal Stroop task and a spatial one were administered to a total of 111 healthy young individuals, for whom T1-weighted magnetic resonance imaging (MRI) images were also acquired. Surface thickness and area estimations were calculated using FreeSurfer. Participants' hemispheres were registered to a symmetric template and Lat…
