Regular skiing and running at low altitudes can delay aging

Most biologists and medical professionals would agree that skiing and running can delay aging. This is essentially because of the direct positive impact on the body due to good exercise and physical fitness.

Study finds narrowed upper airways in preterm infants that may explain higher OSA risk

Infants born preterm have significantly lower nasopharyngeal and oropharyngeal volumes, compared with newborn peers carried to full term, and those lower airway volumes are independent of the infants' gender, ethnicity or weight, according to a study published online Dec. 16, 2017 in Clinical Imaging.

Stem cells remain healthy following low-dose X-ray exposure, say biophysicists

Biophysicists have shown that following low-dose exposure to X-rays (at 80 milligrays), stem cells remain healthy, proliferate, and do not accumulate DNA damage to be passed on to their progeny. The paper was published in the journal Aging.

Cell phones should be kept away from the body warn California health officials

Last week the California Department of Public Health (CDPH) issued a guideline that would help the public reduce the radiation exposure from cell phones. The guidelines clearly state that cell phones need to be kept away from the body.

Papillomaviruses linked to UV light promote development of non-melanoma skin cancer

UV radiation has been known for a long time to be a risk factor for the development of skin cancer. Simultaneous infection with human papillomaviruses (HPV) has also been suspected to promote skin cancer, particularly in organ transplant recipients.

Researchers focus on use of protective shielding against stray radiation during CT scans

Radiation exposure during diagnostic imaging such as computed tomography (CT) contributes to a small, but potentially preventable percentage of cancers, yet a new study reports that 40% of hospitals surveyed do not routinely utilize CT shielding.

Yale scientists unravel molecular mechanism of breast cancer risk gene

More than 20 years after scientists revealed that mutations in the BRCA1 gene predispose women to breast cancer, Yale scientists have pinpointed the molecular mechanism that allows those mutations to wreak their havoc.

Child with abdominal pain more likely to receive CT scan in general ED, study finds

A child with non-traumatic abdominal pain, a common symptom of appendicitis, is more likely to receive a computed tomography (CT) scan in a general emergency department (ED) than if he or she visited a pediatric emergency department, according to a study published in Pediatrics.

Low-level radiation exposure poses less threat to health than modern lifestyle risks

Human populations have always been exposed to ionizing radiation, and more so in modern life due to its use in medicine, industry and the armed forces.

Melanomas mostly from from new spots rather than existing ones

According to a new study appearing this week in the Journal of the American Academy of Dermatology, melanomas do not grow from existing moles and skin growths, but from new ones. Therefore it is vital that people keep a careful eye for new growths over their skin in order to detect early stages of melanomas.

Incisionless surgery method can safely treat painful bone tumors, study shows

Doctors from the Sheikh Zayed Institute for Pediatric Surgical Innovation at Children's National Health System have completed a clinical trial that demonstrates how osteoid osteoma, a benign but painful bone tumor that commonly occurs in children and young adults, can be safely and successfully treated using an incisionless surgery method called magnetic resonance-guided high-intensity focused ultrasound (MR-HIFU).
