Why we could all do with a siesta

...fe Sciences. "We have pinpointed how glucose ?the sugar in food ?can stop brain cells from producing signals that keep us awake. Dr Burdakov's research has shown exactly how glucose blocks or 'inhibits' neurons that make orexins ?tiny proteins that are vital for normal regulation of our state of consciou...

Herbal medicine silymarin may help sugar-control in people with type II diabetes

...elping people with diabetes to control their blood sugar levels. The herbal medicine extracted from seeds... can help people significantly lower the amount of sugar bound to haemoglobin in blood, as well as reducing fasting blood sugar levels. Silymarin contains...

Eat less, weigh more? Enzyme makes lean mice 'susceptible' to dietary fat

...h energy cells need. Many cells in the body use a sugar called glucose as a source of energy. When the body is starved, the body literally feeds on itself, breaking down fat to form fatty acids that fuel energy needs. When the cells of the body are well fed and energy is in ample supply, molecular signa...

Five new technologies that promise to transform medicine

...art and breathing rates, blood pressure, and blood sugar levels. And further into the future are links smart pumps that, when signalled, instantly deliver the correct medication. Another prediction is the use of miniature telescopes that restore vision for patients with degenerative eye disease. The tel...

New data from NIH lab confirms protocol to reverse type 1 diabetes in mice

...d islet cell and hastened the restoration of blood sugar levels. The direct contribution of spleen cells to islet recovery, first described in the 2003 study, is confirmed in the current work. NIH researchers used cell lineage tracking in the form of Y-chromosomal fluorescence in situ hybridization (FI...

Psst! Coffee drinkers: Fruit flies have something to tell you about caffeine

...y testing whether mutant fruit flies prefer eating sugar over sugar laced with caffeine. Using a simple behavioral test, the researchers discovered that a single prote...

A green way to slag off bunnies

...act as an effective fertilizer in rice paddies and sugar cane fields. And as it’s not an active chemical, it could circumvent the convoluted pesticide regulatory approval pathway and be used straight away. ...

Genomic comparison of lactic acid bacteria published

...of these diverse species offered a window into the sugar metabolism and energy conversion systems of LAB, and the evolution of these systems, which helped identify key enzymes involved in the production of end products including acetic acid, lactic acid, ethanol, and CO2." "This work represents a hallma...

Holiday gluttony can spell disaster for undiagnosed diabetics

...re-diabetes: People have higher-than-normal blood sugar levels but the levels are not high enough for a diabetes diagnosis. Type 1 : The immune system attacks insulin-producing beta cells in the pancreas, requiring insulin to survive. This typically affects children. Type 2: The body can't efficien...

New mechanism underlying pain found

...waking. Made up of glycoproteins, or proteins with sugar molecules attached, pacemaker channels -- also known as HCN channels (Hyperpolarization activated, Cyclic Nucleotide-gated cation channels) -- allow the entrance of sodium ions into the cell based on the configuration of the protein. Entry of sodium ...

Jefferson scientists find high glucose before surgery raises risk of dangerous complications

Engineer ramps up protein production, develops versatile viral spheres

...owing for the first time how glucose, the abundant sugar produced by photosynthesis and used in many organisms, can be used to power cell-free protein synthesis. "We are delighted to honor Professor Swartz with the Gaden Award this year," says journal Editor Douglas S. Clark, a chemical engineering profe...

Developing uses for sugar-cane bagasse: Biotechnology applied to the paper industry

...venient means of usefully clearing this voluminous sugar refinery waste product: indeed, one tonne of refined sugar results in two tonnes of bagasse. However, whatever the raw material used, paper pulp has to undergo...

From managing sugar to managing healing

...nsulin is a hormone known primarily for regulating sugar levels in the blood, yet researchers at the University of California, Riverside, recently found that applying insulin directly to skin wounds significantly enhanced the healing process. Skin wounds in rats treated topically with insulin healed faste...
