The synergistic effect of enzymatic detergents on biofilm cleaning from different surfaces.

Biofilm growth is a significant source of contamination in the food industry. Enzymes are considered green countermeasures against biofilm formation in the food industry owing to their biodegradability and low toxicity. In this study, the synergistic effect of enzymes was studied against biofilm cleaning from hard surfaces.

Unusual twin pregnancy: complete hydatidiform mole with coexistent normal fetus.

The authors present a case of complete hydatidiform mole and coexisting fetus (CHMCF) in which mole gestation caused a placenta previa; with a posterior preterm premature rupture of membranes (PPROM) and ending in the 28h week of gestation due to acute chorioamnionitis, obtaining a live preterm newborn.

[Research and professional practice in speech therapy].

The relationship between research and clinical practice is discussed based on the request of this last on new therapeutic perspectives and empirical confirmations of their decisions. Two examples of a clear and justified relation between theoretical research data and the later development of an intervention program illustrate the achievements and disappointments of these relationships. From this analysis, the proposal of evidence-based practice is discussed, the requirements involved and the difficulties in its practical application, especially in the intervention in aspects such as semantics and pragmatics.

[Inferences and verbal comprehension in children with developmental language disorders].

We review the concept of inference in language comprehension -both oral and written- recalling the different proposals of classification. We analyze the type of difficulties that children might encounter in their application of the inferences, depending on the type of language or development pathology. Finally, we describe the proposals for intervention that have been made to enhance the ability to apply inferences in language comprehension.

[Clinical usefulness of the classifications of developmental language disorders].

There have been several proposals for the classification of language disorders in children; some of them are based on the desire to differentiate in terms of its possible cause, while others are based on the criteria for symptoms grouping ('syndromes'), in order to facilitate the diagnostic process and orientate some intervention programs. In the first part, there is an analysis of the advantages and limitations of the most popular classifications, pointing to the inaccuracy on description basis and to the inability to distinguish between several subgroups. In the second part, it is analysed the clinical purpose of using these nomenclatures.
