Measurement of delayed fluorescence in N with a streak camera.

Using a streak camera, we directly measure time- and space-resolved dynamics of emission from a self-seeded filament. Fluorescence emission does not start with ionization, but with a delay in the tenth of ps range.

Trends in folic acid supplementation during pregnancy - the effect on allergy development in children.

Introduction: The results of some previous studies suggested that maternal folate supplementation during pregnancy may contribute to allergy development in offspring.

Aim: This study was performed to examine the influence of maternal folic acid intake prior to and during pregnancy on the development of various types of allergy in children taking into account the timing and dosage of supplemented folate.

Material And Methods: The retrospective study was performed between 2010 and 2014 in 307 child-mother pairs (203 allergic children and 104 children without allergy symptoms, aged 2-72 months).

Folate status, regulatory T cells and MTHFR C677T polymorphism study in allergic children.

Purpose: This study aimed to investigate early-life folate serum concentrations in children with food, inhalant or mixed type allergy. The influence of folate levels on the FoxP expression in Treg (regulatory T) cells in the studied children, taking into account the MTHFR (5,10-methylenetetrahydrofolate reductase) genotypes was also analyzed.

Material And Methods: The study was performed in 83 allergic children (study group) and 49 healthy children (control group), aged 2-72 months.

Pre- and postnatal exposure of children to tobacco smoke during the first four years of life--observations of the authors.

Introduction: Environmental exposure to tobacco smoke is a significant threat for human health, where the higher is its degree, the more immature the human organism is. Therefore, the exposure to Tobacco smoke in foetal life exerts unfavourable effects on developing foetus and may cause early and distant results in children.

Material And Methods: The study comprised 318 children in their first four years of life, treated for various medical conditions.

Prevalence of atopic dermatitis in infants during the first six months of life: authors' observations.

Introduction: Atopic dermatitis (AD) is a frequent chronic skin disease in infants. It creates great difficulties, both diagnostic and therapeutic.

Aim: To assess the prevalence of atopic dermatitis in infants during the first 6 months of life.
