A cherry on top: Tart cherries may alter heart/diabetes factors

...the process by which the body burns fat instead of storing it, and it is important in the formation of blood lipids like LDL, typically known as the "bad cholesterol". Drugs in the classes known as thiazolidinediones and glitazars activate PPAR and are often used to manage high cholesterol and risk for Type ...

Machine preservation may promote more organ sharing

...n a pump ?as opposed to the conventional method of storing and transporting organs in a cooler ?may lower hospital costs, improve initial organ function, and promote greater use and more sharing of organs, according to new research by Wake Forest University Baptist Medical Center. "By placing kidneys on a p...

...s of the lipids used to make membranes involved in storing and communicating information in the brain. These lipid changes were partially reversed in patients treated with antipsychotic medications, said Joseph McEvoy, M.D., associate professor of biological psychiatry and study co-investigator. "This tec...

Columbia scientists determine 3-dimensional structure of cell's 'fuel gauge'

...PK directs cells toward "anabolic" activities like storing the extra energy as fat. When ATP is low, AMPK turns off anabolic activities, and activates "catabolic" functions, like burning fat to make energy. AMPK provides an especially promising drug target for people with type 2 diabetes. These patients...

New biofuels process promises to meet all US transportation needs

... by the existing infrastructure for delivering and storing today's fuels is a huge deterrent to introducing technologies that use only batteries or hydrogen alone," Agrawal said. "A major advantage of our process is that it would enable us to use the current infrastructure and internal combustion engine tech...

UCLA/Toronto researchers unlock key to memory storage in brain

...brain assigns cells to participate in encoding and storing memories. Now a UCLA/University of Toronto team has discovered that a protein called CREB controls the odds of a neuron playing a role in memory formation. The April 20 edition of Science reports the findings, which suggest a new approach for prese...

Experience affects new neuron survival in adult brain; study sheds light on learning, memory

...t brain could contribute to learning and memory by storing the information of one’s previous experiences," Gage says. Future research, he says, should focus on understanding when new neurons are active during memory-related behavior, how experience affects this activity, and what the consequences are for oth...

Lower carbon dioxide emissions from coal-fueled power plants possible with technology development

... well the process works and evaluate an option for storing captured carbon dioxide. For process verification, Rochelle will work with colleagues at the college’s Center for Energy and Environmental Resources at the Pickle Campus. The colleagues, part of the Separations Research Program, oversee the small...

Birds found to plan for the future

... from their previous experiences of food scarcity, storing food for future use in places where they anticipate future slim pickings. The researchers at the University of Cambridge believe this is the first known example of future planning in animals. On alternate mornings eight jays were given breakfast in ...

Major link in brain-obesity puzzle found

...authors suspect that fat-cell SH2B1 encourages the storing of fat. When they tested this theory, they found that SH2B1 appeared to help mouse embryonic cells turn into fat cells, a process called adipogenesis. But, they suspect, the action of SH2B1 in the brain trumps its action in fat tissue, leading to the...

Vaccine-producing 'plant-factories'

...hloroplast is a cell organ with great capacity for storing proteins. However, it is incapable of producing glycosylate proteins. The newly discovered route connects the cell organ where the proteins are glycosylated, the reticulum, with the chloroplasts. This discovery signifies the first step in the deve...

Ferns provide model for tiny motors powered by evaporation

...ogged, the sporangium remained closed like a fist, storing the spores safely inside. But when the water in the outer wall evaporated, it caused the sporangium to unfurl and eject the spores into the environment. The researchers examined some fern leaves under a microscope. They found that when exposed to l...

How ants find their way

...er. Accurate memory retrieval often relies on ants storing a large panorama." A better understanding of ant navigation could help to develop autonomous robots. Professor Collett explained: "Insect behaviour is much more 'machine-like' than that of mammals, and ants are a lot less flexible in their use of n...

Mayo Clinic study suggests that a central nervous system viral infection can lead to memory deficits

... -- the part of the brain responsible for forming, storing and processing memory. Inflammation-induced damage to the brain is believed to be associated with learning and memory deficits. Because picornaviruses are widespread and infection is common, the potential for this family of viruses to damage the hu...

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

... liver sure isn't going to tell you, it just keeps storing fat as long as the body is well fed." Instead, he notes, it is the control regions of the brain, namely the hypothalamus, that governs eating behavior. Previously, the same researchers showed that a molecule called malonyl-CoA is critical for fat me...

Common carp sheds new light on surviving in extreme environments

...rom low levels of oxygen in the tissues apart from storing oxygen, and we need to reassess its importance. It may be that the kind of damage caused in humans by low oxygen levels, could be countered by the therapeutic elevation of myglobin levels or by other treatments that mimic its effects.

New egg freezing technique offers hope to hundreds of women

...itres) of a special vitrification solution, before storing in liquid nitrogen. This process prevents ice crystals forming, which do so much damage to the structure of the egg. Dr Kuwayama froze 111 eggs, of which 94.5% survived freeze-thawing, 90.5% were fertilised using ICSI (intra-cytoplasmic sperm injecti...

Septum keeps neurons in synch, can reduce epileptic seizures by 90 percent
