Why heart attacks cause so much more damage in late pregnancy Posted: 02 Jul 2012 01:24 PM PDT While research has shown that the heart typically functions better during pregnancy due to a rise in cardiac pumping capacity to meet increased demands, a new study in rats and mice demonstrates that heart attacks occurring in the last trimester or late months of pregnancy result in worse heart function and more damaged heart tissue than heart attacks among non-pregnant females. This early study may help identify and better understand the mechanisms involved in the higher risks of heart disease during pregnancy.

Naked mole rat may hold the secret to long life Posted: 02 Jul 2012 01:23 PM PDT The naked mole rat's brain contains unusually high levels of NRG-1, a neuroprotecting protein, which preserves high activity, bone health, and cognitive ability throughout its lifespan, new research shows. And because the rodent has an 85 percent genetic similarity to humans, continuing investigation could lead to a longer and healthier life for us.

Researchers block pathway to cancer cell replication Posted: 02 Jul 2012 01:23 PM PDT Research suggests that patients with leukemia sometimes relapse because standard chemotherapy fails to kill the self-renewing leukemia initiating cells, often referred to as cancer stem cells. In such cancers, the cells lie dormant for a time, only to later begin cloning, resulting in a return and metastasis of the disease. One such type of cancer is called pediatric T cell acute lymphoblastic leukemia, often found in children, who have few treatment options beyond chemotherapy.

In vitro study identifies potential combination therapy for breast cancer Posted: 02 Jul 2012 01:23 PM PDT A new study demonstrates an effective combination therapy for breast cancer cells in vitro.

Cell biology: New insights into the life of microtubules Posted: 02 Jul 2012 01:22 PM PDT Every second, around 25 million cell divisions take place in our bodies. This process is driven by microtubule filaments which continually grow and shrink. A new study shows how so-called motor proteins in the cytosol can control their dynamics.

Surprising culprit behind chemo resistance in rare cancer Posted: 02 Jul 2012 01:21 PM PDT Researchers have shown how an aggressive form of multiple myeloma resists chemotherapy. Multiple myeloma is a rare cancer of plasma cells in the bone marrow. Though the finding has no immediate benefit for patients, the scientists say it could help guide research into better treatments.

Physical activity needed to reap benefits of dietary restriction Posted: 02 Jul 2012 01:21 PM PDT Dietary restriction alone does not extend lifespan – at least in fruit flies. Flies, which share many genetic similarities with humans, need physical activity in order to live longer on a Spartan diet. If the same axiom holds true in humans, those practicing caloric restriction in hopes of living longer need to make sure they eat enough to avoid fatigue.
