1. Does mismatch negativity have utility for NMDA receptor drug development in depression?
Rapid antidepressant effects associated with ketamine have shifted the landscape for the development of therapeutics to treat major depressive disorder (MDD) from a monoaminergic to glutamatergic model. Treatment with ketamine, an N-methyl-D-aspartate (NMDA) receptor antagonist, may be effective, but has many non-glutamatergic targets, and clinical and logis

2. Non-alpine primary thyroid angiosarcoma
SUMMARY Thyroid angiosarcoma is an extremely rare malignancy, which occurs more frequently in the alpine region, likely associated with iodine deficiency and endemic goiter. This is an aggressive neoplasm that usually harbors a poor prognosis. We report the case of a 49-year-old Portuguese female patient presenting with a large nodule in the anterior neck re

3. Mismatch Negativity Elicited by Verbal and Nonverbal Stimuli: Comparison with Potential N1
Abstract Introduction Mismatch negativity (MMN) is a long latency auditory evoked potential, represented by a negative wave, generated after the potential N1 and visualized in a resulting wave. Objective To identify the time of occurrence ofMMNafter N1, elicited with verbal and nonverbal stimuli. Methods Ninety individuals aged between 18 and 56 years

4. Mismatch Negativity Occurrence with Verbal and Nonverbal Stimuli in Normal-Hearing Adults
Abstract Introduction The mismatch negativity (MMN) is a long-latency auditory evoked potential related to a passive elicited auditory event. Objective To verify the occurrence of MMN with different stimuli, to describe reference values in normal-hearing adults with verbal and nonverbal stimuli and to compare them with each other, besides analyzing the l

6. Interrelation Among Morphology, Mechanical Properties and Oxidation Behavior of NbxAlyNz Thin Films
NbxAlyNz thin films were deposited by magnetron sputtering reactive technique with (y/x+y) ratio varying from 0 to 0.4, in order to maintain aluminum atoms inside NbN matrix in solid solution. GAXRD analyses revealed that the crystalline phase obtained for NbxAlyNz thin films was B1-NbN with a lattice constant shrinkage as Al concentration at these coatings

7. Mismatch Negativity in Childrenwith Cochlear Implant
Abstract Introduction The mismatch negativity (MMN) is a negative long-latency auditory potential elicited by any discriminable change in a repetitive aspect of auditory stimulation. This evoked potential can provide cortical information about the sound processing, including in children who use cochlear implants. Objective To identify MMN characteristics

8. Mismatch Negativity in Children: Reference Values
Abstract Introduction The Mismatch Negativity (MMN) auditory evoked potential evaluation is a promising procedure to assess objectively the ability of auditory discrimination. Objective To characterize the latency and amplitude values of MMN in children with normal auditory thresholds and without auditory complaints. Methods Children between 5 and 11 y

11. Prevalence of schistosomiasis mansoni in indigenous Maxakali villages, Minas Gerais, Brazil
ABSTRACT Intestinal parasitic infections are a common health problem among Amerindian populations and schistosomiasis represents one of the most prevalent diseases in Maxakali people. The Kato-Katz is the diagnostic method recommended by WHO for epidemiological studies; however, one of the technique’s limitations is the failure to detect parasites in indiv

12. Amusia e seus correlatos eletrofisiológicos na neurofibromatose tipo 1
RESUMO Déficits de processamento auditivo são comuns em pessoas com neurofibromatose tipo 1 (NF1), que também se queixam frequentemente de dificuldades no desempenho musical. Objetivos: Nós investigamos se a NF1 poderia estar associada à amusia, assim como a algum comprometimento da atividade do córtex auditivo primário. Métodos: Dezoito pessoas co
