OBJECTIVE: Sugar-sweetened beverage (SSB) consumption is cited as a major contributor to the U.S. obesity epidemic. The objective of this paper was to leverage insights from behavioral economics to examine whether nudges would entice college students to save meal calories by choosing water over SSBs. METHODS: Three message-based nudge interventions, with washout periods between, were used during the 7-week study. Calorie savings (self-interest), charity (prosocial), or charity-plus-calorie message posters were displayed in a college-based food franchise...

Few would argue that the unique insights brought by studying the typical and atypical development of psychological processes are essential to building a comprehensive understanding of the brain. Often, however, the associated challenges of working with non-standard adult populations results in the more complex psychophysical paradigms being rejected as too complex. Recently we created a child- (and clinical group) friendly implementation of one such technique - the reverse-correlation Bubbles approach - and noted an associated performance boost in adult participants...

OBJECTIVES: Race/ethnic disparities in obesity are widely reported and are often attributed to diet-related factors, such as menu-labeling usage. We aimed to determine whether racial difference exists in menu-labeling usage. METHODS: Data from the 2012 Behavioral Risk Factor Surveillance System were used. Menu labeling was measured from the Sugar-Sweetened Beverages and Menu Labeling module administered in 18 states. We stratified the population into four race/ethnic categories: non-Hispanic whites (reference, n = 66,019, 63%), non-Hispanic blacks (n = 13,623, 13%), Hispanics (n = 14,671, 14%), and others (n = 7336, 7%)...

Plants integrate and monitor low temperature signals to cope with the continual variations in their environment. Arabidopsis thaliana cold responsive-element binding factor 3 (AtCBF3) plays its role in various cellular activities by modulating multiple genes induced under chilling stress. In this work, AtCBF3 transcription was remarkably induced following chilling stress. AtCBF3-overexpressors namely AtCBF3-Rio Grande, AtCBF3-Moneymaker, and AtCBF3-Roma showed defensible response to various levels of chilling stress, while their isogenic wild type plants indicated hypersensitive response to chilling stress...

In Bacillus subtilis, Listeria monocytogenes and in two Mycobacteria, it was previously shown that yvcK is a gene required for normal cell shape, for optimal carbon source utilization and for virulence of pathogenic bacteria. Here we report that the B. subtilis protein YvcK binds to Uridine diphosphate-sugars like Uridine diphosphate-Glucose (UDP-Glc) and Uridine diphosphate-N-acetylglucosamine (UDP-GlcNAc) in vitro. Using the crystal structure of Bacillus halodurans YvcK, we identified residues involved in this interaction...

In ripe fruit, energy mostly derives from sugar, while in over-ripe fruit, it also comes from ethanol. Such ripeness differences may alter the fitness benefits associated with frugivory if animals are unable to degrade ethanol when consuming over-ripe fruit. In the tropical butterfly Bicyclus anynana, we found that females consuming isocaloric solutions mimicking ripe (20% sucrose) and over-ripe fruit (10% sucrose, 7% ethanol) of the palm Astrocaryum standleyanum exhibited higher fecundity than females consuming a solution mimicking unripe fruit (10% sucrose)...

We report novel capillary gel electrophoresis (CGE) with poly(ethylene glycol) (PEG)-based hydrogels for the effective separations of biomolecules containing sugars and DNAs based on a molecular size effect. The gel capillaries were prepared in a fused silica capillary modified with 3-(trimethoxysilyl)propylmethacrylate using a variety of the PEG-based hydrogels. After the fundamental evaluations in CGE regarding the separation based on the molecular size effect depending on the crosslinking density, the optimized capillary provided the efficient separation of glucose ladder (G1 to G20)...

BACKGROUND: Blood-brain barrier (BBB) breakdown and inflammation are critical events in ischemic stroke, contributing to aggravated brain damage. The BBB mainly consists of microvascular endothelial cells sealed by tight junctions to protect the brain from blood-borne substances. Thus, the maintenance of BBB integrity may be a potential target for neuroprotection. Sac-1004, a pseudo-sugar derivative of cholesterol, enhances the endothelial barrier by the stabilization of the cortical actin ring...

The contribution of transcriptional and post-transcriptional regulation to modifying carbon allocation to developing wood of trees is not well defined. To clarify the role of transcriptional regulation, the enzyme activity patterns of eight central primary metabolism enzymes across phloem, cambium, and developing wood of aspen (Populus tremula L.) were compared with transcript levels obtained by RNA sequencing of sequential stem sections from the same trees. Enzymes were selected on the basis of their importance in sugar metabolism and in linking primary metabolism to lignin biosynthesis...

The SAR11 clade (Pelagibacterales) is a diverse group that forms a monophyletic clade within the Alphaproteobacteria, and constitutes up to one third of all prokaryotic cells in the photic zone of most oceans. Pelagibacterales are very abundant in the warm and highly saline surface waters of the Red Sea, raising the question of adaptive traits of SAR11 populations in this water body and warmer oceans through the world. In this study, two pure cultures were successfully obtained from surface waters on the Red Sea, one isolate of subgroup Ia and one of the previously uncultured SAR11 Ib lineage...

Stereoselective synthesis of S-linked trisaccharide glycal of angucycline antitumor antibiotic derhodinosylurdamycin A is described. The synthesis has been accomplished employing our previously reported umpolung S-glycosylation strategy - stereoselective sulfenylation of 2-deoxy glycosyl lithium. It was found that sugar-derived thiocyanate was a better electrophile than corresponding asymmetric disulfide in this type of stereoselective sulfenylation.

With the omnipresence of silver nanoparticles (AgNPs) in our daily consumer products, their release has raised serious concerns. However, the biochemical mechanisms by which plants counteract the toxicity of nanoparticles are largely unknown. This study investigated the exposure of aquatic Wolffia globosa to ATP-nAg (AgNPs coated with adenosine triphosphate), cit-nAg (AgNPs coated with citrate), and Ag(+). Hill reaction activity was basically lost in W. globosa treated with 10mg/L ATP-nAg and Ag(+), while the activity was still maintained at 38...

Proposed distributed reactivity model of dehydration for seedling parts of two various maize hybrids (ZP434, ZP704) was established. Dehydration stresses were induced thermally, which is also accompanied by response of hybrids to heat stress. It was found that an increased value of activation energy counterparts within radicle dehydration of ZP434, with a high concentration of 24-epibrassinolide (24-EBL) at elevated operating temperatures, probably causes activation of diffusion mechanisms in cutin network and may increases likelihood of formation of free volumes, large enough to accommodate diffusing molecule...

We studied the effect of genetic transformation on biologically active compounds (artemisinin and its co-products (ART) as well as sugars) accumulation in Artemisia vulgaris and A.dracunculus "hairy" root cultures. Glucose, fructose, sucrose and mannitol were accumulated in A. vulgaris and A. dracunculus "hairy" root lines. Genetic transformation has led in some cases to the sugars content increasing or appearing of non-relevant for the control plants carbohydrates. Sucrose content was 1.6 times higher in A...

The integration of redox- and reactive oxygen species-dependent signaling and metabolic activities are fundamental to plant acclimation to biotic and abiotic stresses. Previous data suggest the existence of a dynamically interacting module in the chloroplast stroma consisting of cyclophilin 20-3 (Cyp20-3), O-acetylserine(thiol)lyase B (OASTL-B), 2-cysteine peroxiredoxins A/B (2-CysPrx) and serine acetyltransferase 2;1 (SERAT2;1). The functionality of this COPS module is influenced by redox stimuli and oxophytodienoic acid (OPDA) which is the precursor for jasmonic acid...

Dental caries is one of the most prevalent disease (about 50%) in children across the globe. If not treated in time, it can affect not only the mastication function but also the speech, smile and psychosocial environment and the quality of life of the child and the family. The treatment of dental diseases is very expensive in all countries and prevention is very simple and effective. The caries in children below 6 y is called early childhood caries (ECC). It is most commonly caused by milk bottle or mother's feed during night...

Grafting of elite cultivars onto tolerant rootstocks is an advanced strategy to increase tomato tolerance to sub-optimal temperature. However, a detailed understanding of adaptive mechanisms to sub-optimal temperature in rootstocks and scions of grafting combinations on a physiological and molecular level is lacking. Here, the commercial cultivar Kommeet was grafted either onto 'Moneymaker' (sensitive) or onto the line accession LA 1777 of Solanum habrochaites (tolerant). Grafted plants were grown in NFT-system at either optimal (25°C) or sub-optimal (15°C) temperatures in the root environment with optimal air temperature (25°C) for 22 days...
