New biofuels process promises to meet all US transportation needs

...ess, making it possible to produce three times the volume of biofuels from the same quantity of biomass, said Rakesh Agrawal, Purdue's Winthrop E. Stone Distinguished Professor of Chemical Engineering. The researchers are calling their approach a "hybrid hydrogen-carbon process," or H2CAR. "Further re...

Keeping the body in sync -- The stability of cellular clocks

...t, and changes in liver metabolism. In the tiny volume of the cell, however, the chemical environment is constantly fluctuating. How is it possible for all these cell-autonomous clocks to sustain accurate 24-hour rhythms in such a noisy environment? Using mouse fibroblast circadian bioluminescence re...

3-D ultrasound identifies women at risk for impending preterm birth

..., sensitivity and specificity of the adrenal gland volume in predicting preterm birth within five days from ...l ultrasound assessment of the fetal adrenal gland volume can assist clinicians with devising better therapeutic and preventive interventions for preterm birt...

Lithium builds gray matter in bipolar brains, UCLA study shows

...polar patients not on lithium, they found that the volume of gray matter in the brains of those on lithium w...her studies have measured increases in the overall volume of the brain, Bearden said, this imaging method allowed the researchers to see exactly which brain r...

Scientists seek useful traits in wild cottons

...d roller-ginned, and then characterized using high volume instrumentation and the advanced fiber information analysis system. The Lubbock scientists enter this information into a genetic database which they share with other scientists and the public. This database will complement the Texas A&M ...

Tissue engineered scaffolding allows reproduction of cartilage tissue

... allowed the newly grown cartilage to maintain its volume during cultivation and post-procedure. "The cell-derived scaffold could provide a favorable environment for cartilage cells to maintain their characteristics while synthesizing cartilage in the scaffold structure in vivo," notes study author Dr. ...

Gene malfunctions cause schizophrenia, depression symptoms in mice

...tant mice exhibited the same kind of reduced brain volume seen in people with schizophrenia and depression, the researchers found. Also, both types showed biochemical abnormalities in the function of the protein produced by the DISC1 gene. The researchers concluded that the different effects of antipsych...

'Virtual Patient' to simulate real-time organ motions for radiation therapy

...ider such issues as the breathing function and air volume change that are affected by several physiological factors over the course of the radiation treatment." Real-time simulations could allow doctors to spot the small fractions of time when the lungs, liver, kidneys, and eventually the heart, are stat...

Focused ultrasound relieves fibroid symptoms in women

Runners -- Let thirst be your guide

...ising, the AVP is telling your kidney to excrete a volume of fluid that is markedly less than the maximum the kidney can excrete at rest,” Verbalis says. Too much water intake in an endurance exerciser whose AVP levels are on the rise means that some of the ingested water will be retained, and that excess w...

Warning from Asian bees

... intruders are nowhere near the same league in the volume of honey they produce. In the recent experience of Papua New Guinea and the Solomon Islands, they could become a serious pest, not just for beekeepers, but of concern to agriculture generally. Bees play a big role in the food supply chain. “...

Research shows cord blood comparable to matched bone marrow

...eet certain standards in relation to cell dose (or volume of the transplanted cells) and Human Leukocyte Antigen (HLA) diversity. Human Leukocyte Antigens (HLA) are a group of proteins on bone marrow cells that can provoke the immune system to respond. When doing bone marrow or cord blood transplants, do...
