Glowing dye may aid in eliminating cancer

When a solid cancer is surgically removed, any small piece that is left behind increases the chance of a local recurrence or spread. In a pilot study of dogs with mammary tumors, a disease very similar to human breast cancer, a team found that an injectable dye, which glows under near-infrared light, illuminated cancerous growth in the primary tumor as well as in lymph nodes.

Discovery of key protein behind cancer relapse and progression can lead to new therapies

Reports show that cancer is the second-highest leading cause of death globally. A recent study by scientists provides new evidence supporting the presence of a key mechanism behind progression and relapse in cancer. The study discusses the role of MBNL1 protein as a biomarker for cancer prognosis, which can lead to the development of new treatment strategies for cancer.

Two new, powerful small molecules may be able to kill cancers that other therapies can't

Scientists have identified and developed two potent small molecules that appear to suppress tumor growth in multiple cancers even when other treatments cease to work, possibly due to the development of drug resistance. Called CS1 and CS2, these cancer inhibitor compounds are part of a protein known as ''fat mass and obesity-associated protein.'' This FTO protein plays a critical role in cancer development and progression, primarily because it regulates cancer stem cells and immune evasion.

3D X-ray reveals secrets from inside bones

Researchers have uncovered a previously unknown substructure in bone tissue using a new X-ray technique to produce 3D images of the internal structure of bones. The discovery potentially questions fundamentally a number of the models of bone tissue and the mechanical properties of bones that, among other things, is used to describe the process of bone formation.

A good vitamin D status can protect against cancer

A good vitamin D status is beneficial both in cancer prevention and in the prognosis of several cancers, according to a new research review. The anti-cancer effects of vitamin D are especially pronounced in the prevention and treatment of colon cancer and blood cancers. In addition, high vitamin D responsiveness can be linked to a smaller cancer risk. Vitamin D responsiveness varies between individuals, affecting their need for vitamin D supplementation.

Different hormone therapies affect brain function differently

Sex hormones influence the structure and function of the brain, but little is known about the effect of hormone therapies (HT) on changes in the brain during menopause. A new study shows smaller increases in structural brain changes related to aging were associated with hormone-level changes from transdermal estradiol or oral conjugated equine estrogen.

Physical activity in all of its forms may help maintain muscle mass in midlife

Loss of estrogen has an effect on muscles and leads to a decline in muscle mass. Physical activity in all of its forms may help maintain muscle mass in midlife.

'Terminator' protein halts cancer-causing cellular processes

New research finds that a protein called TiPARP acts as a terminator for several cancer-causing transcription factors, including HIF-1, which is implicated in many cancers, including breast cancer. The research demonstrates that TiPARP, therefore, is a tumor suppressor.

Probiotics with top-performing Lactobacillus strains may improve vaginal health

Vaginal Lactobacillus bacterial strains largely perform better than strains currently used in probiotics for vaginal health, according to a new study. The findings suggest that a vaginal health probiotic that includes top-performing vaginal Lactobacillus strains may improve treatment options for bacterial vaginosis.

Disrupted sleep increases the risk of cardiovascular disease by promoting inflammation

Sleep disruption has been shown to be associated with an increased risk of atherosclerosis, but the mechanism has been unclear. A new study reveals that fragmented sleep exacerbates atherosclerosis and may raise the risk of stroke via an effect on inflammatory pathways.
