ACUTE CHANGES IN TASTE RECEPTORS. "Our taste preferences may fluctuate with our hormones...many pregnant women in their first trimester can't stand the sight of vegetables...pregnant women crave foods that tend to be high energy sources." Is this hormonally regulated? Maternal biome changes occur throughout pregnancy. https://lnkd.in/eDcVrhp View in LinkedIn

NEW INSIGHTS. "The discovery of photonic crystals, periodic dielectric materials with a photonic band gap, has opened up new methods for controlling light, leading to proposals for many novel devices." https://lnkd.in/e3AZ-X7 View in LinkedIn

ACUTE CHANGES IN BUDS. It is clear that our taste buds and their taste receptors can change acutely in short time intervals, affecting food preferences and caloric intake. The control of these changes is poorly understood. Food preferences, caloric intake, and satiety are undoubtedly controlled, at least in part, by taste receptor composition. View in LinkedIn

"JANUS PARTICLES (JPs) are noncentrosymmetric spherical, cylindrical, or disk-like colloids feauring two phase-separated faces or compartments with distinct differences in chemical and/or physical properties. Over the past two decades, JPs have drawn widespread attention in soft matter nanoscience and materials science, as nanomotors, chemical or optical sensors, for programmable self-assembly and bio-medical applications." https://lnkd.in/eEJEhhZ View in LinkedIn

GUT BIOME SYMBIOSIS. "Gut bacteria aid digestion by breaking down otherwise indigestible plant fibers into short-chain fatty acids that intestinal cells can access." The normal microbiome plays a key role in maintaining our health, that we know. But gut fermented SCFAs turn out to be critical microbial signals to the host, as well as providing nutrition. https://lnkd.in/eCbaTsv View in LinkedIn

BIOME REGULATION OF TASTE RECEPTORS. Sweet taste receptor genes in taste buds in the mouth can be down-regulated by bacterially-derived lipopolysaccharides, which modulates the transmission of taste input to the brain. This is a direct connection, at least in mice, between oral taste receptors and the microbiome. http://www.researchgate.net/publication/258443568_Ingestion_of_bacterial_lipopolysaccharide_inhibits_peripheral_taste_responses_to_sucrose_in_mice View in LinkedIn

FRAGMENT IN NATURE continues this weekend with the theme of the interaction of the microbiome with taste receptors and that effect on satiety, food selection and health. These is little literature on the effects of the microbiome directly on taste receptors in the mouth, but intuitively, it is a likely control point for these symbiotic bacteria in their host nutritional status.

BIOME EFFECT IN TASTE RECEPTORS. Microbiota can modulate mouse host taste receptor expression in the mouth and gut, and thereby affect their food preferences. Cultured human epithelial cells' receptors could also be induced by microbiota samples. A brilliant review. https://lnkd.in/eknVNSM View in LinkedIn

PHASE UTILITY. "Optoelectronic phase change materials (PCM) have markedly different optical reflectivity and electrical conductivity in their disordered and ordered phases. They can be switched rapidly and reversibly between their better conducting crystalline and the more insulating amorphous phases. Owing to their properties, PCMs are used as non-volatile memory materials and bear promise as materials for programmable logic circuits." https://lnkd.in/eC9wHtZ View in LinkedIn

HYPOTHESIS: BACTERIA CONTROL HOST APPETITE. Gut microbiota affects the host appetite, since food selection affects the gut microbiota ecology; equally, stress in the host releases stress hormones that change the gut ecology. The growing list of molecules used by bacteria to control host behaviour exceeds 24. http://jb.asm.org/content/195/3/411.full View in LinkedIn
