Promising clinical trial results for drug for rare disease in which patients can't eat fat

People with familial chylomicronemia syndrome are born with a genetic mutation that means they can’t produce an enzyme called lipoprotein lipase. Without the enzyme, their bodies can’t break down dietary-derived fat in the blood. Instead, fat-carrying molecules called chylomicrons build

Philippines 'open' to dengue vaccine as outbreak kills hundreds

As hundreds die in a severe dengue outbreak in the Philippines, many of them children, President Rodrigo Duterte said Thursday he was open to lifting his government’s blanket ban on the Dengvaxia vaccine. Manila prohibited the import, sale and distribution

One cell at a time, researchers create a blueprint of liver cells in health and disease

In every tissue throughout our bodies, various cell types are communicating and coordinating their efforts to perform vital functions and maintain health. In a new study led by the University of Michigan, researchers have now created a high-resolution picture of

White kids take twice as many antibiotics as other kids, putting them at higher risk, study finds

Antibiotic resistance is a growing problem around the world, and a new study shows that white children are particularly vulnerable to developing it. The Children’s National Health System carried out a study that examined the differences between the care white

A new pathway: Researchers identify potential treatment target for Crohn's disease

There is no cure for the more than 1.6 million people in the United States living with Crohn’s disease (CD) and its symptoms, including abdominal pain, intestinal distress and severe weight-loss. CD is a form of inflammatory bowel disease (IBD)

Implantable 3-D blastocyst-like embryonic structure generated from mouse stem cells

An international collaboration of researchers from the RIKEN Center for Biosystems Dynamics Research (BDR) in Japan and Gladstone Institutes in the U.S. have generated 3-D blastocyst-like structures from stem cells. Published in the journal Stem Cell Reports, the study shows

Researchers identify barriers to fungal infection diagnosis

There are several barriers that prevent the consistent use of fungal diagnostic preparations to correctly identify cutaneous fungal infections, according to a survey from a team at the George Washington University (GW). The study is published in the Journal of

Mayo Clinic minute: Children should have MMR vaccine for first day of school

As families around the country get ready to send their children off to school—and some for the first time—it’s important to ensure their vaccinations are up to date. Dr. Robert Jacobson, a Mayo Clinic pediatrician, explains why the measles, mumps

Many risk factors contribute to worsening of quality of life in people with knee OA

A new study from the University of Eastern Finland shows that the health-related quality of life of most people who have had or have a higher risk of knee osteoarthritis remained unchanged over an eight-year trajectory. Worsening of quality of

Pancreatic cancer: Less toxic, more enduring drug may improve therapy

Unlike many other cancers, most pancreatic tumors are rock hard.  “That’s one reason why pancreatic cancer is one of the most lethal types of cancer,” says Kenneth Olive, Ph.D., associate professor of medicine and pathology & cell biology at Columbia University Vagelos

Reducing exposure to opioids after cesarean delivery

An effort to improve the scheduled cesarean section delivery experience found that changes to preoperative and postoperative processes can lead to reductions in opioid use without increased pain and with faster recovery, according to research from Kaiser Permanente published in

How cigarette smoke makes head and neck cancer more aggressive

Head and neck cancer is the sixth most common cancer in the world. The vast majority of cases are head and neck squamous cell carcinoma (HNSCC), a type of cancer that arises in the outer layer of the skin and

Researchers identify subtypes of squamous cell lung cancer

Lung cancer is the number one cause of cancer-related deaths in the United States, with squamous cell lung cancer (SCC) being one of the common types. Despite improved knowledge of the molecular alterations in SCC, little is understood about how

Targeting apolipoprotein E could be key to eliminating hepatitis B virus

Different gammaherpesviruses suppress largely overlapping host cellular pathways

The discovery of thousands of host mRNAs targeted by gammaherpesvirus microRNAs (miRNAs) could shed light on the biology of gammaherpesviruses and how these pathogens establish lifelong infections, according to a study published August 8 in the open-access journal PLOS Pathogens

Study finds specific microbiome tied to long-term survival of patients with pancreatic cancer

A key difference between the few pancreatic cancer patients who survive long-term and the many whose disease overcomes all treatments is the bacterial signatures on their tumors that either stimulate or suppress immune response, a team led by researchers from

Positive effect of music and dance on dementia proven in study

Stereotypically viewed as passive and immobile, a University of Otago pilot study has shown the powerful influence music and dance can have on older adults with dementia. Researchers from the Department of Dance and Department of Psychological Medicine used familiar,

Balance of 'stop' and 'go' signaling could be key to cancer immunotherapy response

A crucial signaling pathway that can tell the immune system to fight off cancer can also be co-opted by cancer cells to put the brakes on the immune system, according to a new study from researchers in the Abramson Cancer

The world's smallest stent

Researchers at ETH Zurich have developed a new method for producing malleable microstructures—for instance, vascular stents that are 40 times smaller than previously possible. In the future, such stents could be used to help to widen life-threatening constrictions of the

Researchers discover why intense light can protect cardiovascular health

Researchers at the University of Colorado Anschutz Medical Campus have found that intense light amplifies a specific gene that bolsters blood vessels and offers protection against heart attacks. “We already knew that intense light can protect against heart attacks, but
