The component helminth community in six sympatric species of Ardeidae.

2005

We studied the helminth communities in 6 sympatric species of Ardeidae (Ixobrychus minutus (Linnaeus, 1766), Nycticorax nycticorax (Linnaeus, 1758), Bubulcus ibis (Linnaeus, 1758), Egretta garzetta (Linnaeus, 1766), Ardea cinerea (Linnaeus, 1758), and Ardea purpurea (Linnaeus, 1766)) from "La Albufera de Valencia," Spain. The survey revealed 13 species of helminth parasites: 5 digeneans, 2 cestodes, and 6 nematodes. The component helminth communities of the Ardeidae examined are depauperate and conform to the pattern typically found in isolationist communities, probably because of their high trophic dependence on a few prey species. Evenness was positively correlated with richness and abund…

Despite increasing interest in the development of audiovisual speech perception in infancy, the underlying mechanisms and neural processes are still only poorly understood. In addition to regions in temporal cortex associated with speech processing and multimodal integration, such as superior temporal sulcus, left inferior frontal cortex (IFC) has been suggested to be critically involved in mapping information from different modalities during speech perception. To further illuminate the role of IFC during infant language learning and speech perception, the current study examined the processing of auditory, visual and audiovisual speech in 6-month-old infants using functional near-infrared s…

Bestiari Llatí Polisemàntic: un Estudi Motivacional

2015

La tesi és un estudi semàntic diacrònic dels cinquanta zoònims llatins més productius de significats figurats o metasèmies; alhora constitueix una anàlisi motivacional de la creació de lèxic nou en general, i zoonímic en particular. Es constata que els zoònims constitueixen segurament el camp semàntic de més capacitat per a un ús figurat metafòric o metonímic. S'analitzen, doncs, les 16 derives semàntiques dels zoònims llatins, que per ordre de major freqüència a menor freqüència són les següents: noms de persona (antropònims), noms de plantes o fruits (fitònims), noms de caràcter, especialment insults i termes afectuosos (etònims), noms de lloc (topònims), noms d'animals procedents de noms…

Abstract Proprioceptive paired-stimulus paradigm was used for 30 children (10–17 years) and 21 adult (25–45 years) volunteers in magnetoencephalography (MEG). Their right index finger was moved twice with 500-ms interval every 4 ± 25 s (repeated 100 times) using a pneumatic-movement actuator. Spatial-independent component analysis (ICA) was applied to identify stimulus-related components from MEG cortical responses. Clustering was used to identify spatiotemporally consistent components across subjects. We found a consistent primary response in the primary somatosensory (SI) cortex with similar gating ratios of 0.72 and 0.69 for the children and adults, respectively. Secondary responses with…

Oral myiasis in a cerebral palsy patient: A case report

2010

Myiasis is a rare condition caused by the invasion of tissues by the larvae of flies, mainly from the order of Diptera. Many cases of myiasis involving various human organs have been reported. Oral Myiasis is very rare in healthy persons. It occurs mainly in the tropics and is usually associated with inadequate personal and public hygiene; sometimes accompanied by poor manual dexterity. We present a case of oral myiasis in a mentally retarded, 13- year-old boy suffering with cerebral palsy. The diagnosis was based on the characteristic clinical features and the visualization of wriggling larvae. Large numbers of larvae were found in the gingival sulcus. Treatment consisted of manual removal…

OC2.01: Examination of the fetal brain by three-dimensional ultrasound: potential for routine neurosonographic studies

2005

Objective: To evaluate the role of three-dimensional (3D) ultrasound in the assessment of the fetal brain and its potential for routine neurosonographic studies. Methods: We studied prospectively 202 consecutive brain fetuses between 16 and 24 weeks’ gestation. A 3D-ultrasound volume of the fetal head was acquired transabdominally. The entire brain anatomy was later analyzed by a sonologist expert in neonatal cranial sonography using the multiplanar images. The quality of the conventional planes obtained (coronal, sagittal and axial, at different levels) and the ability to visualize properly the major brain anatomic structures were evaluated. Results: Acceptable rendered cerebral volumes we…

Posterior Tibial Tendon Dislocation: A Case Report

2022

Abstract Isolated posterior tibial tendon dislocation is a rare condition. Diagnosis can be challenging, especially in the acute clinical setting. Predisposing factors include shallow posterior tibial tendon groove and tear of the flexor retinaculum. We report the case of traumatic subluxation of the posterior tibial tendon, illustrating imaging findings and surgical technique. Posterior tibial tendon dislocation was detected using dynamic ultrasound, while magnetic resonance was essential for a comprehensive evaluation that included underlying predisposing anatomic abnormalities and associated pathologic conditions. Conservative treatment is often unsuccessful thus surgical approach was ne…
