Columbia research lifts major hurdle to gene therapy for cancer

...f the major hurdles ingene therapy for cancer: its tendency to kill normal cells in theprocess of eradicating cancer cells.In a new study published in the Jan. 25 issue of the Proceedings of theNational Academy of Sciences (PNAS), the researchers demonstrated thatthe technique works by incorporating it into a...

How the environment could be damaging men's reproductive health

... transport over long distances. POPs have a strong tendency to bioaccumulate in marine and terrestrial food webs. Humans, being at the top of the food web, particularly are exposed to POPs." The researchers found that larger amounts of both CB-153 and DDE in the blood of the fishermen was associated with a s...

Liposome finding implies electrical effect on cell development

...nd Michele Pysher have found that liposomes have a tendency to form tube-like extensions in their membranes through the influence of local electrical fields. In particular, the surprising finding of such electrically caused bionanotubule formation may reveal a previously unknown process involved in the develo...

New project aims to make large-scale lobster farms feasible

...he lobster's more fascinating habits such as their tendency to crawl in huge single-file lines when crossing open areas between island coasts and reefs, will be the focus of the next Harbor Branch Ocean Science Lecture Series event, on March 9. "Spiny lobsters are one of the most highly-prized fisheries spec...

The lopsided brain: Attention bias is shared by humans and birds

...ot entirely clear, during some tasks humans have a tendency to devote more visual attention to the left side of the visual world than the right side, a phenomenon known as pseudoneglect. Researchers now report that pseudoneglect is not restricted to humans but is shared by birds, suggesting not only that brai...

Nanobacteria in clouds could spread disease, scientists claim

...remely efficient cloud condensation nuclei, with a tendency to aggregate to clusters upon contact." Their work corroborates the findings of Ruprecht Jaenicke, of the Institute for Atmospheric Physics at Mainz University, Germany, on bioaerosols (airborne contaminants) and proteins in the atmosphere reported ...

Men Estimate Men's Risks Of Common Disorders Higher Than Women Do, And Vice Versa

... for their own sex than for the opposite sex. This tendency was also evident in the one condition -- fitness -...ous studies on personal risk assessments suggest a tendency to underestimate one's own risk of illness compared to one's peers -- this is often referred to as o...

Space matters: Estimating species diversity in the fossil record

... rule of thumb called the species-area effect: the tendency for species number, or richness, to increase in a predictable way with area. Paleontologists have been unable to account for the species-area effect, or to even know whether it applies, in estimating paleodiversity because of various confounding fact...

Gene therapy advance treats hemophilia in mouse models

...of normal to within 5 to 10 percent of normal, the tendency for spontaneous bleeding and need for hospitalization would diminish dramatically," McCray said. "In the mouse model in our study, we were able to achieve levels of gene expression that converted the hemophilia A in the mouse from a severe to a mil...

Gene controlling circadian rhythms linked to drug addiction

... a link in disruption of circadian rhythms and the tendency to abuse drugs. "Most work on Clock has focused on the brain's master pacemaker, located in a brain area called the suprachiasmatic nucleus," said Dr. Nestler. "The novelty of Dr. McClung's findings is the role Clock plays in brain reward pathways. ...

What comes first…the chicken, the egg, or the bad attitude?

...nscious thing the bird does, but it does express a tendency of that bird to either be generous or to be selfish with its nutrients." Channelling food into body-building results in lower egg production, chick production and chick quality, said Dr. Frank Robinson, professor of Agricultural Food and Nutritional...

'Shifty-eyed' Monkeys Offer Window Into Brain's Social Reflexes

... direction of the monkey-image gaze. The reflexive tendency to follow gaze is, indeed, powerful, said Platt. 'It's really striking when you're sitting there, and you look at these faces pop up,' he said. 'You feel yourself wanting to look in that same direction.' Platt said that the finding offers the promise...

Discovery of T-cell 'traffic control' boosts new drug promise

...e tired easily, experienced lower blood flow and a tendency for airways to constrict as muscle walls develop abnormally, Goetzl says. "Fully exploiting this approach for treatment of autoimmune diseases and transplant rejection will depend on developing new drugs that block only the immune type of S1P recept...

Columbia scientists develop cancer terminator viruses

...come one of the major hurdles of gene therapy: its tendency to kill normal cells in the process of eradicating cancer cells. The virus eradicated prostate cancer cells in the lab and in animals, while leaving normal cells unscathed. The present cancer "terminator" viruses represent the next generation of ...

UCSD discovery may provide novel method to generate medically useful proteins

... very challenging because the loops would have the tendency to fold incorrectly. "Because of its stability, the phage protein makes a better model to create protein diversity in a test tube," explained Jason Miller, a graduate student in Ghosh's lab who conducted much of the research. "Our discovery shows...

Chernobyl: The true scale of the accident

... Also, widespread expectations of ill health and a tendency to attribute all health problems to radiation exposure have led local residents to assume that Chernobyl related fatalities were much higher than they actually were. What diseases have already occurred or might occur in the future? Residents who at...

But using modern molecular-genetic and imaging processes, researchers from the Max Planck Institue for Marine Microbiology in Bremen and Max Planck Institute of Biochemistry in Martinsried, Germany have identified ...

Anti-cancer drugs may hold promise for premature aging disorder

... proper integration into the lamina. If progerin's tendency to stick to the inner nuclear membrane is indeed the culprit in nuclear blebbing and the root of the progeria defect, Capell and his colleagues reasoned that they could prevent these defects by blocking farnesylation of progerin. The researchers' h...

Machinery of the 'marijuana munchies'

And while scientists have traced this property to cannabinoid receptors in the brain, they have had little understanding of the neural circuitry underlying this effect. Understanding this circuitry has important practical implic...
