Study provides new insights into mechanism that controls differences in gut's ability to fight infections

Considering how many microorganisms we ingest each day, our gut has an extensive and well-developed immune system. This defense is involved in acute and chronic gut diseases, but it varies dramatically among people. A persistent question is how our genetic make-up affects our gut's ability to fight infections. EPFL scientists have found that gut immunity is not affected by single genes but by entire groups of genes.

New model helps to answer longstanding question in cancer science

A paper published today in the Proceedings of the National Academy of Sciences argues against the commonly held "accumulation of mutations" model of oncogenesis in favor of a model that depends on evolutionary pressures acting on populations of cells.

Dietary phosphate appears to cause spikes in blood phosphorus levels

Phosphates artificially added to dairy and cereal products appear to cause bigger spikes in blood phosphorus levels than naturally occurring phosphates, potentially putting harmful stress on kidneys. Too much dietary phosphate stiffens blood vessels, enlarges the heart and is bad for bones, but a new study by Houston Methodist researchers suggests it matters where the phosphates come from.

Aging may trigger adaptive response to offset effects of oxidative stress on blood vessels

Although the causes of many age-related diseases remain unknown, oxidative stress is thought to be the main culprit. Oxidative stress has been linked to cardiovascular and neurodegenerative diseases including diabetes, hypertension and age-related cancers. However, researchers at the University of Missouri recently found that aging actually offered significant protection against oxidative stress.

Iowa researchers gain important insight into sudden unexpected death in epilepsy

Sudden unexpected death in epilepsy (SUDEP) is becoming increasingly recognized as a very real and devastating problem in which impaired breathing is thought to play a critical role. Researchers believe breathing may be impaired during and after seizures, without the patient's knowledge.

Family, cultural and geographical factors influence unsafe sleep position of infants

When it comes to newborn sleep, mother may not know best. According to Deborah Raines, associate professor in the University at Buffalo School of Nursing, family, cultural and geographical influences may lead some mothers to place their newborn children in unsafe sleeping positions.

Researchers create clinical pathway to identify OSA in high-risk, hospitalized patients

Obstructive Sleep Apnea (OSA) remains under-recognized in hospitalized patients, despite being associated with cardiovascular complications and sudden death. A multi-disciplinary group of researchers and physicians at Thomas Jefferson University and Hospitals have created a clinical pathway, or screening process, to identify the disorder in higher-risk, hospitalized patients and recently published the results in the Journal of Clinical Sleep Medicine.

Hyperbaric oxygen treatment effective for fibromyalgia

Fibromyalgia is almost impossible to diagnose. The chronic pain syndrome strikes an estimated 1 in 70 Americans, most of them women. The disorder is often triggered by head trauma, a neurological infection, or severe emotional stress, and is characterized by symptoms such as musculoskeletal pain, fatigue, memory loss and mood swings. Fibromyalgia is often mistaken for other culprits and most patients suffer months, even years, of unrelenting pain before being properly diagnosed. And once diagnosed, patients enjoy little respite because few therapies have been found to be effective in assuaging its symptoms.

Innovation in anaesthesia: an interview with Matti Lehtonen, GE Healthcare

The spectrum of patients seen today, from pre-term infants to the morbidly obese to the longer living elderly, is wider than ever before and increasingly more challenging with patients often presenting with multiple co-morbidities. This puts a huge strain on healthcare providers who are facing increasing challenges such as cost pressure and staff shortages.

Study offers new way to suppress growth factors related to cancer cell proliferation

Cancer cells need life-essential molecules to proliferate. These so-called growth factors are activated by ectodomain shedding of precursor proteins on the outside of the plasma membrane, mainly carried out by three human cleavage enzymes. A pharmaceutical blocking of these enzymes could hinder cancer from growing but would also inhibit other life-essential processes.

Potential molecular link identified between excess fat in the blood and blood vessel recovery in ischemia

The buildup of fat in the blood makes a bad situation worse - it not only raises a person's risk for heart attack or stroke but also impairs the growth of new blood vessels. How excess fat in the blood - a condition known as hyperlipidemia - blocks vessel growth was unclear, but new work by researchers at Temple University School of Medicine shows that a molecule known as caspase-1 plays a central role and that preventing its activity could be the key to building new blood vessels and restoring blood supply to oxygen-starved tissues.
