Novel approach for treating non-cardiac chest pain suggested

Novel approach for treating non-cardiac chest pain suggested

Chest pain doesn’t necessarily come from the heart. An estimated 200,000 Americans each year experience non-cardiac chest pain, which in addition to pain can involve painful swallowing, discomfort and anxiety. Continue reading

Cosmic rays threaten future deep-space astronaut missions

Cosmic rays threaten future deep-space astronaut missions

Crewed missions to Mars remain an essential goal for NASA, but scientists are only now beginning to understand and characterize the radiation hazards that could make such ventures risky, concludes a new paper by University of New Hampshire scientists. Continue reading

Treatment for osteoporosis, bone cancer, employed for the first time in dental filling procedures

Treatment for osteoporosis, bone cancer, employed for the first time in dental filling procedures

Journal of Dental Research publishes a paper directed by Salvatore Sauro, Professor at University CEU Cardenal Herrera in Spain, in collaboration with international researchers from Finland, Brazil, United States and United Kingdom. The research report has demonstrated how the use of zoledronic acid, in combination with bioactive ion-releasing resin-based restorative materials used as dental adhesive, reduces the degradation of dentin collagen and promotes remineralisation at the resin-dentine interface.

Resetting the circadian clock: Shift workers might want to skip high-iron foods at night

Resetting the circadian clock: Shift workers might want to skip high-iron foods at night

Workers punching in for the graveyard shift may be better off not eating high-iron foods at night so they don’t disrupt the circadian clock in their livers. Continue reading

Obesity link to increased risk for orthopedic conditions, surgical complications

Obesity link to increased risk for orthopedic conditions, surgical complications

Obesity affects individual patient care, the healthcare system and nearly every organ in the body. People with obesity often have other health problems, including diabetes, heart disease, certain tumors and cancers, and psychiatric disorders. Continue reading

Patients treated with radiation therapy who have tumors in left breast have comparable overall survival to those with tumors in right breast

Patients treated with radiation therapy who have tumors in left breast have comparable overall survival to those with tumors in right breast

Tumor laterality (left-side vs. right-side) does not impact overall survival in breast cancer patients treated with breast-conserving surgery and adjuvant external beam radiation therapy, according to a study published in the October 1, 2014 issue of the International Journal of Radiation Oncology • Biology • Physics (Red Journal), the official scientific journal of the American Society for Radiation Oncology (ASTRO). Studies have shown that breast cancer patients treated with radiation therapy have improved local-regional recurrence, and breast cancer-specific survival after breast-conserving surgery and overall survival (OS) after mastectomy Continue reading

Lab-developed intestinal organoids form mature human tissue in mice

Lab-developed intestinal organoids form mature human tissue in mice

Researchers have successfully transplanted “organoids” of functioning human intestinal tissue grown from pluripotent stem cells in a lab dish into mice — creating an unprecedented model for studying diseases of the intestine. Continue reading

Many older people have mutations linked to leukemia, lymphoma in their blood cells

Many older people have mutations linked to leukemia, lymphoma in their blood cells

At least 2 percent of people over age 40 and 5 percent of people over 70 have mutations linked to leukemia and lymphoma in their blood cells, according to new research at Washington University School of Medicine in St. Louis. Mutations in the body’s cells randomly accumulate as part of the aging process, and most are harmless Continue reading

‘Mega’ cells control growth of blood-producing cells

‘Mega’ cells control growth of blood-producing cells

While megakaryocytes are best known for producing platelets that heal wounds, these “mega” cells found in bone marrow also play a critical role in regulating stem cells according to new research from the Stowers Institute for Medical Research. In fact, hematopoietic stem cells differentiate to generate megakaryocytes in bone marrow. The Stowers study is the first to show that hematopoietic stem cells (the parent cells) can be directly controlled by their own progeny (megakaryocytes). Continue reading

How a molecular Superman protects genome from damage

How a molecular Superman protects genome from damage

How many times have we seen Superman swoop down from the heavens and rescue a would-be victim from a rapidly oncoming train? It’s a familiar scenario, played out hundreds of times in the movies. But the dramatic scene is reenacted in real life every time a cell divides Continue reading
