Background: To evaluate the effect of different oral glucose or sucrose solutions on the pain response to heelstick in newborns.
Design: randomised double blind placebo controlled trial of water (control) versus one of three solutions of glucose - namely 5, 33 and 50% - or one of two solutions of sucrose (33% and 50%) or nothing.
Setting: postnatal ward.
Patients: seven groups of 20 healthy newborns (gestational age 38-41, weighing over 2500 g) were randomised to receive 2 ml of one of the six solutions on the tongue inmediately before heelstick procedure.
Main Outcome Measure: heart rate before, during and three minutes after the procedure.
Results: Even if the trend of the cardiac rates did not reach statistic significance, glucose solution 33 and 50% proved to be the most effective in reducing pain response.
Conclusions: Sweet solutions may be an easy, useful, safe and cheap analgesic for minor invasive procedures in newborns.

Enhancing nitrogen (N) fixation in rice plants can reduce N fertilizer application and contribute to sustainable rice production, particularly under low-N conditions. However, detailed microbial and metabolic characterization of N fixation in rice stems, unlike in the well-studied roots, has not been investigated. Therefore, the aim of this study was to determine the active N-fixing sites, their diazotroph communities, and the usability of possible carbon sources in stems compared with roots.

Sugar limitation has dramatic consequences on plant cells, which include cell metabolism and transcriptional reprogramming, and the recycling of cellular components to maintain fundamental cell functions. There is however no description of the contribution of epigenetic regulations to the adaptation of plant cells to limited carbon availability. We investigated this question using nonphotosynthetic grapevine cells (, cv Cabernet Sauvignon) cultured with contrasted glucose concentrations.

Context: The obesity epidemic parallels an increasing type 1 diabetes incidence, such that westernized diets, containing high fat, sugar and/or protein, through inducing nutrient-induced islet beta-cell stress, have been proposed as contributing factors. The broad-spectrum neutral amino acid transporter (B0AT1), encoded by Slc6a19, is the major neutral amino acids transporter in intestine and kidney. B0AT1 deficiency in C567Bl/6J mice, causes aminoaciduria, lowers insulinemia and improves glucose tolerance.

Introduction: Sweet potato is an important food, feed and industrial raw material, and its tubers are rich in starch, carotenoids and anthocyanins.
Methods: To elucidate the gene expression regulation and metabolic characteristics during the development of sweet potato tubers, transcriptomic and metabolomic analyses were performed on the tubers of three different sweet potato varieties at three developmental stages (70, 100, and 130 days (d)).
Results: RNA-seq analysis revealed that 16,303 differentially expressed genes (DEGs) were divided into 12 clusters according to their expression patterns, and the pathways of each cluster were annotated.

D-allose is a rare monosaccharide, found naturally in low abundances. Due to its low-calorie profile and similar taste to sucrose, D-allose has the potential to become an ideal sugar substitute. D-allose also displays unique properties and health benefits that can be applied to various fields, including food and medicine.
