[Modulation of energy metabolism of lymphocytes in children by natural physical factors]

Area of Science:

• Pediatric endocrinology and environmental health.
• Investigating age-dependent energy metabolism in children.

Context:

• Longitudinal study over 11 years examining healthy and premature children.
• Environmental factors including solar activity, geomagnetic field, and atmospheric conditions were monitored.
• Cytochemical analyses were performed annually until age six.

Purpose:

• To explore how natural physical factors affect age-dependent energy exchange parameters, specifically succinate dehydrogenase (SDH) activity.
• To understand the relationship between environmental factors and developmental trajectories in children.
• To compare these effects in healthy versus premature infants.

Summary:

• Geomagnetic field activity appears to be a key factor, with quieter periods potentially correlating with higher SDH activity.
• Increased magnetic field activity may shift the peak age of SDH activity earlier.
• Lymphocytes exhibit a phasic response to magnetic storms, and other environmental factors may have counteracting effects.
• Prenatal exposure to high solar activity may enhance early development but is linked to lower later SDH activity.
• Premature children show depressed hydrogenase activity in the final stage, unlike healthy children whose SDH activity remains within a normal, potentially beneficial range.

Impact:

• Findings suggest environmental monitoring could inform pediatric health strategies.
• Highlights the sensitivity of infant development to subtle environmental changes.
• Provides insights into potential biomarkers for developmental health in response to environmental stimuli.
