First in-depth profile of CAR T-cell signals suggests how to improve immunotherapy

21.08.2018 Health Problems

CAR T-cell therapy, which reprograms immune cells to fight cancer, has shown great promise in people with some blood cancers who have not responded to other treatments. But until now, the underlying biological pathways enabling anti-cancer responses have not been thoroughly examined. Understanding these pathways is important for designing future generations of CAR T-cell therapies, including reducing side effects, preventing […]

New clues into how ‘trash bag of the cell’ traps and seals off waste

16.08.2018 Health Problems

The mechanics behind how an important process within the cell traps material before recycling it has puzzled scientists for years. But Penn State researchers have gained new insight into how this process seals off waste, much like a trash bag. The process, called autophagy, allows cell waste and damaged material in the cell to be recycled into energy or new […]

How gambling distorts reality and hooks your brain

13.08.2018 Health Problems

To call gambling a “game of chance” evokes fun, random luck and a sense of collective engagement. These playful connotations may be part of why almost 80 percent of American adults gamble at some point in their lifetime. When I ask my psychology students why they think people gamble, the most frequent suggestions are for pleasure, money or the thrill. […]

Button batteries kill—here’s how we can prevent needless child deaths from battery ingestion

10.08.2018 Kids Health

In 2013, four-year-old Summer Steer died from acute blood loss several days after swallowing a button battery. She hadn’t told her family she’d swallowed anything, so they didn’t know what was wrong. At least not until the caustic reaction caused by the battery, which had lodged in her oesophagus, ate through to her aorta. She presented to hospital with a […]

Study provides insight into how dying neurons control eating behaviors of the brain microglia

24.07.2018 Health Problems

A new Mount Sinai study, published July 23 in the journal Nature Neuroscience, provides important insight into how microglia, cells that form a branch of the immune system inside the brain, go about their job of clearing out dying and non-functional neurons—and how they sometimes mistakenly attack healthy neurons, an event that can play a role in neurodegenerative diseases like […]

Researchers solve mystery of how ALL enters the central nervous system

20.07.2018 Health Problems

A deadly feature of acute lymphoblastic leukemia (ALL) is its invasion of the central nervous system. ALL in the central nervous system is very difficult to treat, because most drugs are blocked from the organ system due to a “blood-brain barrier” designed to protect the brain. How cancer cells enter the central nervous system has been an unanswered question for […]

How I Found Myself After My Mother's & Son's Suicide Attempts

06.07.2018 Kids Health

There are no words to describe the feelings that washed over my body when the phone rang and I heard, “Your mom’s in the hospital; she took a lot of pills and her organs are close to shutting down.” Or when I walked into the laundry room in my house and found my 16-year-old son standing with a chair in […]

How to Make Summer Camp Prep a Breeze

29.06.2018 Kids Health

Summer is upon us, which means long days of fun in the sun stretch ahead of us — or at least for our kids. While we’re stepping into our stuffy, hot suits to trek to work with business as usual, our kids are getting ready for summer camp. But what if it’s their first time away? How do you help […]

Science Says: How family separation may affect kids’ brains

28.06.2018 Health Problems

Doctors have long known that separating families and other traumatic events can damage children’s well-being. More recent research has shed some light on how that may happen: Severe early adversity may cause brain changes and “toxic stress,” resulting in lasting psychological and physical health problems. A “zero-tolerance” immigration policy announced this spring by the Trump Administration has separated 2,300 children […]

Scientists explore how high blood pressure hurts cognition

26.06.2018 Health Problems

The squeeze high blood pressure puts on fragile blood vessels in the brain appears to disrupt a normal, protective process that balances the blood flowing to our brains with the activity of our resting neurons. In the face of hypertension, as blood flow decreases, neuron-nurturing brain cells called astrocytes may instead tell neurons to increase their activity, says Dr. Jessica […]
