Optimization of thin film-microextraction (TF-SPME) method in order to determine musts volatile compounds.

It is well known that grape aromatic composition is directly correlated to the final wine quality. To determine this composition, a previous stage of selective extraction is necessary, since the aromatic compounds are found in very low concentrations in the grapes. Therefore, in this work, the thin film microextraction technique (TF-SPME) was optimized, for first time, with the aim to analyze the volatile composition of the grape musts.

Maternal anxiety following delivery, early infant temperament and mother's confidence in caregiving.

A mother's emotional state is a well-known environmental factor that relates to the development of infant temperament. However, some relevant issues have not yet been fully explored. The current study examines the influence of determined maternal, contextual and perinatal variables on infant temperament and the mother's confidence in caregiving during the first weeks of life.

[Spanish adaptation of the EAS Temperament Survey for the assessment of child temperament].

Better understanding of child temperament is essential, as it may predict subsequent development of psychopathology. Questionnaires which have been adapted to Spanish population include a rather restricted age range. The Emotionality Sociability and Activity (EAS) Temperament Survey has been widely used in child temperament genetic research.

Gene-environment interaction of child temperament.

Objective: The aims of this study were to review studies on the molecular genetics of child temperament and prospectively analyze infant temperament as a function of the interaction between infant and mother: 5-HTT, DRD4, and MAO-A functional polymorphisms and the mother's emotional state.

Method: A prospective study of 317 newborns and their mothers was performed. Infant temperament and the mother's anxiety and confidence in caregiving were evaluated at 8 and 32 weeks after childbirth using the Mother and Baby Scale.

Thyroid function 48h after delivery as a marker for subsequent postpartum depression.

Physiological changes during gestation and after delivery are associated with postpartum thyroid dysfunction, which is due to thyroid autoimmunity in some cases. Postpartum thyroid dysfunction, in turn, has been associated with postpartum depression (PPD). The aim of the present study was to evaluate whether thyroid function immediately after delivery can predict postpartum depression at 8 weeks and 32 weeks after delivery.

Glucosamine sulfate effect on the degenerated patellar cartilage: preliminary findings by pharmacokinetic magnetic resonance modeling.

Normal and degenerated cartilages have different magnetic resonance (MR) capillary permeability (K(trans)) and interstitial interchangeable volume (v(e)). Our hypothesis was that glucosamine sulfate treatment modifies these neovascularity abnormalities in osteoarthritis. Sixteen patients with patella degeneration, randomly distributed into glucosamine or control groups, underwent two 1.

Reduced expression of NO-sensitive guanylyl cyclase in reactive astrocytes of Alzheimer disease, Creutzfeldt-Jakob disease, and multiple sclerosis brains.

In Alzheimer's disease (AD) brains increased NO synthase (NOS) expression is found in reactive astrocytes surrounding amyloid plaques. We have recently shown that treatment with beta-amyloid peptides or IL-1beta down-regulates NO-sensitive soluble guanylyl cyclase (sGC) in cultured astrocytes and in adult rat brain. In this work, we have examined sGC activity and expression in postmortem brain tissue of AD patients and matched controls.
