|Title:||Impact of nucleotides and nutritional support on growth and body composition of severely malnourished infants|
|Abstract:||Understanding neuron connections is a great challenge, which is needed to solve many important problems in neurobiology and neuroengineering for recreation of brain functions and efficient biorobotics. In particular, a design of an optical synapse capable to communicate with neuron spike sequences would be crucial to improve the functionality of neuromimmetic networks. In this work we propose an optical synaptic sensor based on an erbium-doped fiber laser driven by a FitzHungNagumo electronic neuron, to connect with another electronic neuron. Two possible optical synaptic configurations are analyzed for optoelectronic coupling between neurons: laser cavity loss modulation and pump laser modulation. The control parameters of the proposed optical synapse provide additional degrees of flexibility to the neuron connection traditionally controlled only by coupling strengths in artificial networks.

An infinite moving grating is simulated on the LCD spatial modulator, on a screen with 128 240 pixels, which is handled by a microcontroller program in which the direction and velocity of the displacement, and also the fill factor and spatial period, can be defined.

An accepted approach has not been established by most health professionals attending malnourished infants. The objective of this study was to determine if an improvement in the growth rate and body composition of infants with PEM occurred after receiving a starting infant formula with nucleotides. Twenty-five malnourished infants from 3 to 18 months of age participated in the study. All were fed through a nasogastric tube with infant formula (3.35 kJ/mL) for 2 weeks and ad libitum for another 2 weeks. Direct and indirect anthropometric indicators were determined. The subjects were divided into 2 groups; group 1 (n = 11) was fed a formula with added nucleotides, and group 2 (n = 9), with no nucleotides. A paired t test was used to determine the differences between the initial and final measurements for each group, and nonpaired t test was used to compare the groups. Indicators of growth and fat incorporation showed significant differences within each group (P < .001). The comparison of the rate of anthropometric changes showed no significant difference between the groups. Skin fold thickness and fat percentage were higher but not significant in group 2. An infant formula with an intake of 837 kJ/kg per day and protein of 4 g/kg per day in infants with PEM had a favorable impact on growth, fat incorporation, and body composition indicators regardless of the addition of nucleotides.
