Chemical-sensing cells in the gums protect the mouth from infections

Newly discovered chemical-sensing cells in the gums protect the mouth by standing guard against infections that damage soft tissue and destroy the bone that supports the teeth, report researchers from the Monell Chemical Senses Center in an animal study published this week in Nature Communications.

Study finds evidence of blood-brain barrier damage even without reported concussion

In a new study of adolescent and adult athletes, researchers at Ben-Gurion University of the Negev, Stanford University and Trinity College in Dublin have found evidence of damage to the brain's protective barrier, without a reported concussion.

The ear's sensitivity to sound is controlled by outer hair cells

The human inner ear has a type of cell called the outer hair cell. These were thought to amplify sounds from the environment. However, a new study based on hearing in gerbils shows these cells are probably involved in regulating the sensitivity of the ear to sound. This could help find ways to preserve good hearing by protecting these cells from destruction.

Mummies show atherosclerosis was prevalent in ancient times

A new study published in the American Heart Journal used spectroscopic imaging techniques to ‘see’ fatty plaques in the arteries of ancient mummies. This shows that the people of ancient times also had a high incidence of clogged arteries, showing that heart disease is of very old lineage.

Ear's tiny outer hair cells regulate sound sensitivity, study shows

The ear’s tiny outer hair cells adjust the sensitivity of neighboring inner hair cells to sound levels rather than acting like an amplifier, suggests a new study published today in eLife.

Algorithm helps physicians to assess whether stroke patients are candidates for clot-removing procedure

An algorithm developed by faculty at The University of Texas Health Science Center at Houston can help physicians outside of major stroke treatment centers assess whether a patient suffering from ischemic stroke would benefit from an endovascular procedure to remove a clot blocking an artery.

Heart disease was bigger issue for human ancestors than originally thought, study reveals

A new imaging study of the mummified arteries of people who lived thousands of years ago revealed that their arteries were more clogged than originally thought, according to a proof-of-concept study led by a researcher with The University of Texas Health Science Center at Houston.

MRI shown to be a powerful tool in the detection and prevention of minor stroke

Recently, researchers discovered that strokes in low risk patients could be predicted and potentially even prevented using MRI.

QUT researchers use deep learning methods for more accurate eye testing

Queensland University of Technology researchers have applied artificial intelligence deep learning techniques to develop a more accurate and detailed method for analyzing images of the back of the eye to help clinicians better detect and track eye diseases, such as glaucoma and age-related macular degeneration.

Nanoscale syringe-like bacterial structures could be used to deliver novel drugs

By scraping tubeworms off the bottom of boats in the San Diego harbor to study them, San Diego State University researchers discovered that a beneficial bacterium that aids them in establishing colonies could also be a boon for human health, because the same process might already take place in the human gut.

Radiation therapy reduces episodes of deadly rapid heart rhythm

A single high dose of radiation aimed at the heart significantly reduces episodes of a potentially deadly rapid heart rhythm, according to results of a phase one/two study at Washington University School of Medicine in St. Louis.

Researchers identify changes in retinal layers of patients with mild Alzheimer's disease

Researchers at the Complutense University of Madrid have identified changes in retinal layer thickness, inflammation or thinning in patients with mild Alzheimer's disease, confirming that the retina is one of the most important biomarkers for early diagnosis of the disease.

ECLS trial demonstrates potential of blood test for early lung cancer detection

Oncimmune Holdings plc, a leading global immunodiagnostics group, welcomes the presentation of data today by Professor Frank Sullivan (Chief Investigator on the ECLS trial) which has demonstrated the potential of Oncimmune’s EarlyCDT Lung test to reduce the incidence of patients with late-stage lung cancer at diagnosis, compared with standard clinical diagnosis.

Brain changes may help track people most likely to develop dementia

Even before dementia diagnosis, people with mild cognitive impairment may have different changes in the brain depending on what type of dementia they have, according to a study published in the September 11, 2019, online issue of Neurology, the medical journal of the American Academy of Neurology.

Medical imaging rates continue to increase despite broad campaign to reduce their use

Despite a broad campaign among physician groups to reduce the amount of imaging in medicine, the rates of use of CT, MRI and other scans have continued to increase in both the U.S. and Ontario, Canada, according to a new study of more than 135 million imaging exams conducted by researchers at UC Davis, UC San Francisco and Kaiser Permanente.
