Aspirin use best for those with high coronary calcium, low risk of bleeding

An X-ray test commonly used to assess hardening of the arteries could help doctors decide whether the benefits of taking aspirin to prevent a first heart attack or stroke outweigh the risks of bleeding from its use, research suggests.

'Fast' MRI detects breast cancers that 3-D mammograms may miss

In a retrospective study of asymptomatic patients, all of whom had a negative 3-D mammogram within the previous 11 months, abbreviated MRI detected roughly 27 cancers per 1,000 women screened.

What do breast cancer cells feel inside the tumor?

Using a new technique, a team of researchers has found tiny and previously undetectable 'hot spots' of extremely high stiffness inside aggressive and invasive breast cancer tumors. Their findings suggest, for the first time, that only very tiny regions of a tumor need to stiffen for metastasis to take place. Though still in its infancy, the researchers believe that their technique may prove useful in detecting and mapping the progression of aggressive cancers.

Steroid inhalers/pills for asthma linked to heightened risk of brittle bones and fractures

Taking steroid inhalers or tablets to treat asthma or control flare-ups is linked to a heightened risk of brittle bones (osteoporosis) and increased vulnerability to broken bones (fragility fractures), finds new research.

Calcium bursts kill drug-resistant tumor cells

Multidrug resistance (MDR) -- a process in which tumors become resistant to multiple medicines -- is the main cause of failure of cancer chemotherapy. Tumor cells often acquire MDR by boosting their production of proteins that pump drugs out of the cell, rendering the chemotherapies ineffective. Now, researchers have developed nanoparticles that release bursts of calcium inside tumor cells, inhibiting drug pumps and reversing MDR.

Skeletal muscle development and regeneration mechanisms vary by gender

Researchers have generated mice lacking the estrogen receptor beta gene, both fiber-specific and muscle stem cell-specific, which resulted in abnormalities in the growth and regeneration of skeletal muscle in female mice. This was not observed in male mice that lacked the ER-beta gene, suggesting that estrogen and its downstream signals may be a female-specific mechanism for muscle growth and regeneration.

Women's expected longevity linked to age at birth of last child

No one knows for sure how long they will live. A new study, however, suggests that leukocyte telomere length may offer some key insights into a woman's longevity and further demonstrates how maternal age at birth of last child affects telomere length and long-term health.

How an egg cell's 'operating manual' sets the stage for fertility

Scientists have revealed in unprecedented detail the genetic instructions immature egg cells go through step by step as they mature into functionality. Their findings improve our understanding of how ovaries maintain a female's fertility.

Light stimulation makes bones heavier

Researchers showed that laser ablation of bone inhibits expression of the osteogenesis inhibitor protein sclerostin without causing inflammation, unlike the conventional bur-drilling technique. Further investigations confirmed that this beneficial bio-stimulation works by inducing mechanical stress. These findings help advance research into the treatment of osteoporosis as well as specific enhancement of bone regrowth in orthopedic and dental surgery.

Pregnancy complications linked to heightened risk of heart disease and stroke in later life

Pregnancy complications such as miscarriage, pre-eclampsia, diabetes in pregnancy (gestational diabetes) and pre-term birth are linked to a heightened risk of heart disease in later life, suggests an overarching (umbrella) analysis of data.
