Liquid flow and control without solid walls.

When miniaturizing fluidic circuitry, the solid walls of the fluid channels become increasingly important because they limit the flow rates achievable for a given pressure drop, and they are prone to fouling. Approaches for reducing the wall interactions include hydrophobic coatings, liquid-infused porous surfaces, nanoparticle surfactant jamming, changes to surface electronic structure, electrowetting, surface tension pinning and use of atomically flat channels. A better solution may be to avoid the solid walls altogether.

Neonatal renal and inferior vena cava thrombosis associated with fetal thrombotic vasculopathy: a case report.

Background: Fetal thrombotic vasculopathy is a described placental diagnosis associated with adverse perinatal outcomes. It may also predispose children to somatic thromboembolic events. As far as we know, this is the first case of inferior vena cava thrombosis associated with fetal thrombotic vasculopathy in a completely asymptomatic newborn.

Low breast milk IgA and high blood eosinophil count in breast-fed newborns determine higher risk for developing atopic eczema after an 18-month follow-up.

Eosinophil count and IgA breast milk were evaluated at birth in 120 mother-newborn pairs with an 18-month prospective follow-up study. Our study showed a higher risk of developing atopic eczema in newborns with eosinophil count higher than 500 cell/mm3 and with IgA breast milk less than 220 mg/dl (odds ratio 17.6 CI 5.

Basophil count in neonates is not suitable for atopy predictivity.

Basophil granulocytes and their mediators are involved in the pathogenesis of allergic inflammation. We evaluated basophil count, blood histamine content, eosinophil count and serum total IgE levels in one hundred-thirteen healthy newborns at birth. 102 children were prospectively studied with a follow up to 18 months of age for development of atopic disorders.

[Respiratory function tests in the newborn and the infant].

We evaluated respiratory mechanics in healthy or with respiratory diseases newborns and infants. We used a facial mask collected with a pneumotachograph and a software. We obtained flow-volume and flow-time loops which are useful for evaluating lung function in non collaborating infants.

[Basophil count of the newborn is not useful in prediction of allergic diseases].

Basophil granulocytes and their mediators are involved in the pathogenesis of allergic inflammation. We evaluated basophil count, blood histamine content, eosinophil count and serum total IgE levels in one hundred-thirteen healthy newborns at birth. 108 children were prospectively studied with a follow-up to 18 months of age for development of topic disorders.

[Eosinophils: current knowledge and clinical usefulness in childhood].

We describe the eosinophil granulocyte's immunobiology and pediatric management implications. Moreover, we review our results about eosinophil count in newborn as a predictive marker of atopy.

Usefulness of neonatal eosinophil counts as a marker of atopy?

Eosinophil count (EC) were obtained from 312 newborns with and 172 without family history of atopy (FHA). The EC were higher in infants with than without FHA. Elevated EC were recorded in babies of parietaria sensitive mothers born in the spring, as compared to other seasons.
