UK government claims that patient choice improves health care is based on flawed research, experts say Posted: 09 Oct 2011 04:25 PM PDT Research which claims to show that the introduction of patient choice in the United Kingdom's National Health Service (NHS) reduced deaths from heart attacks is flawed and misleading, according to a new report.

If you don't snooze, do you lose? Wake-sleep patterns affect brain synapses during adolescence Posted: 09 Oct 2011 11:02 AM PDT An ongoing lack of sleep during adolescence could lead to more than dragging, foggy teens, a new study suggests.

Small molecules can starve cancer cells Posted: 09 Oct 2011 11:02 AM PDT Researchers in Denmark have found that a small molecule in our cells can block autophagy in cancer cells making them more sensitive for treatment.

Scientists discover three new gene faults which could increase melanoma risk by 30 percent Posted: 09 Oct 2011 11:02 AM PDT Researchers have discovered the first DNA faults linked to melanoma -- the deadliest skin cancer -- that are not related to hair, skin or eye color.

Novel technique uses RNA interference to block inflammation Posted: 09 Oct 2011 11:02 AM PDT Researchers have found a way to block, in an animal model, the damaging inflammation that contributes to many disease conditions.

New membrane lipid measuring technique may help fight disease Posted: 09 Oct 2011 11:02 AM PDT Chemists have developed a technique which successfully quantifies signaling lipids on live cell membranes in real time, opening up possible new routes for treating diseases.

Blame 'faulty' frontal lobe function for undying optimism in face of reality Posted: 09 Oct 2011 11:02 AM PDT Why, in the face of clear evidence to suggest to the contrary, do some people remain so optimistic about the future? Researchers have shown that people who are very optimistic about the outcome of events tend to learn only from information that reinforces their rose-tinted view of the world. This is related to "faulty" function of their frontal lobes.

Study shows how bookmarking genes pre-cell division hastens their subsequent reactivation Posted: 09 Oct 2011 11:01 AM PDT By observing and measuring the kinetics of activation of a single gene locus in a cell before it divides and comparing it with the same gene's reactivation in newly formed daughter cells, scientists have discovered how how bookmarking a gene pre-division causes it to get reactivated post-division.

Water-soluble 'gelatinase inhibitor' compounds show promise for treating neurological diseases Posted: 07 Oct 2011 01:16 PM PDT Scientists have taken a promising step on the road to developing new drugs for a variety of neurological diseases. The researchers focused on the design, synthesis and evaluation of water-soluble "gelatinase inhibitor" compounds.

Bone marrow cells migrate to tumors and can slow their growth Posted: 07 Oct 2011 07:33 AM PDT Bone marrow-derived cells participate in the growth and spread of tumors of the breast, brain, lung, and stomach. To examine the role of BMDCs, researchers developed a mouse model that could be used to track the migration of these cells while tumors formed and expanded. Their results strongly suggest that more effective cancer treatments may be developed by exploiting the mechanism by which bone marrow cells migrate to tumors and retard their proliferation.

Strategy for improving health care for uninsured, low-income, and minorities in the US Posted: 07 Oct 2011 04:32 AM PDT A new set of strategies released today by the Commonwealth Fund Commission on a High Performance Health System could dramatically improve how the US health care system serves vulnerable populations -- those in the US who are uninsured, low-income, or members of racial and ethnic minority groups.

Forgotten dementia sufferers helped through art Posted: 07 Oct 2011 04:31 AM PDT While medical researchers continue the search for advanced diagnosis, prevention and treatment of dementia, one researcher is focusing on improving the experiences of those already suffering with the devastating disease for whom any cure would be too late.
