Outpatient parents' views on shared-decision-making at an Italian children's hospital.

Information is lacking on what parents in southern European countries know and how they view clinical shared-decision-making (SDM) for their children. This survey assesses general parental views on SDM and patient-physician SDM relationships in an Italian paediatric outpatients' clinic. In a 3-month cross-sectional survey, we enrolled 458 consecutive native and foreign Italian-speaking parents bringing their children to our public hospital for various reasons.

Casein phosphopeptides modulate proliferation and apoptosis in HT-29 cell line through their interaction with voltage-operated L-type calcium channels.

At the intestinal level, proliferation and apoptosis are modulated by the extracellular calcium concentration; thus, dietary calcium may exert a chemoprotective role on normal differentiated intestinal cells, while it may behave as a carcinogenesis promoter in transformed cells. Calcium in milk is associated with casein and casein phosphopeptides (CPPs), hence is preserved from precipitation. CPPs were demonstrated to induce uptake of extracellular calcium ions by in vitro intestinal tumor HT-29 cells but only upon differentiation.

Casein phosphopeptides promote calcium uptake and modulate the differentiation pathway in human primary osteoblast-like cells.

Casein phosphopeptides (CPPs), originating by in vitro and/or in vivo casein digestion, are characterized by the ability to complex and solubilize calcium ions preventing their precipitation. Previous works demonstrated that CPPs improve calcium uptake by human differentiated intestinal tumor cell lines, are able to re-mineralize carious lesions in a dental enamel, and, as components of a diet, affect bone weight and calcium content in rats. The aim of the present study was to evaluate if CPPs can directly modulate bone cells activity and mineralization.

Caseinphosphopeptide-induced calcium uptake in human intestinal cell lines HT-29 and Caco2 is correlated to cellular differentiation.

Caseinphosphopeptides (CPPs) are considered as mineral carriers because of their ability to bind and solubilize calcium ions, with the possible role, yet to be definitely assessed, of improving calcium absorption at the intestinal level. Previous works demonstrated that CPPs improve calcium uptake, with increasing intracellular calcium concentration, by human differentiated tumor HT-29 cells, and that this effect correlates with the supramolecular structure of CPPs in the presence of calcium ions. The aim of the present study was to establish whether the CPP effect on calcium uptake is specific for HT-29 cells and depends on the differentiated state of the cells.

New methodological approach to induce a differentiation phenotype in Caco-2 cells prior to post-confluence stage.

Background: Various differentiation-inducing agents or harvesting of spontaneously late post-confluence cultures have been used to differentiate the human colon carcinoma Caco-2 cell line. We report a new procedure to generate pre-confluent subcultures of Caco-2 population at various stages of differentiation without altering culture conditions.

Materials And Methods: Ultrastructural analysis, cell proliferation activity and biochemical markers of differentiation were evaluated at different passages.
