Fingerprint and authenticity roasted coffees by H-NMR: the Brazilian coffee case.

With globalization, it has become necessary to adopt policies to regulate the coffee market, addressing problems including the authenticity and traceability of products. It is therefore important to establish methodologies that can help to safeguard the interests of producer countries and add value to products. For this purpose, the use of NMR combined with multivariate statistical procedures can be an attractive option.

Central auditory processing outcome after stroke in children.

Objective: To investigate central auditory processing in children with unilateral stroke and to verify whether the hemisphere affected by the lesion influenced auditory competence.

Method: 23 children (13 male) between 7 and 16 years old were evaluated through speech-in-noise tests (auditory closure); dichotic digit test and staggered spondaic word test (selective attention); pitch pattern and duration pattern sequence tests (temporal processing) and their results were compared with control children. Auditory competence was established according to the performance in auditory analysis ability.

Stroke caused auditory attention deficits in children.

Objective: To verify the auditory selective attention in children with stroke.

Methods: Dichotic tests of binaural separation (non-verbal and consonant-vowel) and binaural integration - digits and Staggered Spondaic Words Test (SSW) - were applied in 13 children (7 boys), from 7 to 16 years, with unilateral stroke confirmed by neurological examination and neuroimaging.

Results: The attention performance showed significant differences in comparison to the control group in both kinds of tests.

Does stroke impair learning in children?

Objective. To assess cognitive development and learning in children who have had strokes. Method.

Prenatal and neonatal variables associated with enamel hypoplasia in deciduous teeth in low birth weight preterm infants.

This study investigated possible prenatal and neonatal variables that may influence the prevalence of tooth enamel hypoplasia in preterm and low birth weight children (LBW) and a matched control group of term children with normal birth weight (NBW). The study sample consisted of 61 children born preterm and with LBW examined at 18-34 months of age. The control group was formed by 61 infants born full term and with NBW examined at 31-35 months of age.
