Fat cells may influence how the body reacts to heart failure, study shows

University of Alberta researchers have found that limiting the amount of fat the body releases into the bloodstream from fat cells during heart failure could help improve outcomes for patients. In a recent study published in the American Journal of Physiology, Jason Dyck, professor of paediatrics in the Faculty of Medicine & Dentistry and director […]

Seeing schizophrenia: X-rays shed light on neural differences, point toward treatment

An international research team used the ultrabright X-rays of the Advanced Photon Source to examine neurons in the brains of schizophrenia patients. What they learned may help neurologists treat this harmful brain disorder. Schizophrenia, a chronic, neurological brain disorder, affects millions of people around the world. It causes a fracture […]

Reactivating Aging Stem Cells in the Brain

As people get older, their neural stem cells lose the ability to proliferate and produce new neurons, leading to a decline in memory function. Researchers at the University of Zurich have now discovered a mechanism linked to stem cell aging – and how the production of neurons can be reactivated. […]

Effective treatment for insomnia delivered in a few short phone calls

Insomnia — trouble falling asleep, staying asleep or waking up too early — is a common condition in older adults. Sleeplessness can be exacerbated by osteoarthritis, the most common form of arthritis causing joint pain. While there are effective therapies for treating insomnia in older adults, many people cannot get […]

Stroke of Luck: Scientists Discover Target for Stroke Therapy in Blood-Brain Barrier

The blood-brain barrier prevents immune cells from circulating freely in the brain, and the breakdown of its function is a major cause of post-stroke inflammation. Now, for the first time, researchers have identified how a toxic stroke byproduct, acrolein, could activate the barrier-degrading enzyme proheparanase (proHPSE). The research group has […]

High fructose diets could cause immune system damage

New research led by Swansea University in collaboration with researchers at the University of Bristol and the Francis Crick Institute in London has indicated that consuming a diet high in sugar fructose might prevent the proper functioning of peoples' immune systems in ways that have, until now, largely been unknown. […]

Sleep is vital to associating emotion with memory, according to U-M study

When you slip into sleep, it’s easy to imagine that your brain shuts down, but University of Michigan research suggests that groups of neurons activated during prior learning keep humming, tattooing memories into your brain. U-M researchers have been studying how memories associated with a specific sensory event are formed […]

An experimental neurofeedback imaging treatment has emerged for psychiatric patients. Does it work?

In recent years, researchers have begun using functional magnetic resonance imaging (fMRI) not just for better understanding the neural bases of psychiatric illness, but also for experimental treatment of depression, ADHD, anxiety, PTSD, substance use disorder, and schizophrenia with a technique called real-time fMRI neurofeedback. While rtfMRI-NF has emerged in recent […]

Yale scientists repair injured spinal cord using patients’ own stem cells

Intravenous injection of bone marrow-derived stem cells (MSCs) in patients with spinal cord injuries led to significant improvement in motor functions, researchers from Yale University and Japan report in the Journal of Clinical Neurology and Neurosurgery. For more than half of the patients, substantial improvements in key functions — such […]

Toward a disease-sniffing device that rivals a dog’s nose

Numerous studies have shown that trained dogs can detect many kinds of disease —  including lung, breast, ovarian, bladder, and prostate cancers, and possibly Covid-19 — simply through smell. In some cases, involving prostate cancer, for example, the dogs had a 99 per cent success rate in detecting the disease […]

AI can predict f­fic­acy of breast cancer treat­ment from morphology of the tumour

Artificial Intelligence has a huge potential in diagnostic medicine. It can run through vast amounts of data very quickly, noticing details that escape the human eye. Now scientists from the University of Helsinki have demonstrated the possibilities to use AI to predict the efficacy of a targeted breast cancer therapy. […]

How do people without the sense of touch feel their body position?

One of the huge problems in developing self-propelled robots is awareness of the body positioning. We as humans and animals have that solved very well – we sense when we touch something and are very aware of the boundaries of our physical selves. But how – is sense of touch […]

New research on mitochondrial function can play significant part in serious disease

Disorders of the cells’ energy supply can cause a number of serious diseases, but also seem to be connected to ageing. More research is needed on a mitochondrial function to find future treatments. A new study involving researchers at Karolinska Institutet shows how an important molecule inside the mitochondria affects […]

How a gene called HAND2 may impact the timing of labor

A new study illuminates how a gene called HAND2 may have a hand in the timing of human labour. “We don’t know why humans go into labour. It’s a basic aspect of human biology that we just don’t know the answer to, and it’s kind of embarrassing that we don’t,” […]

Five Years Later: Penn-developed CAR T Therapy Shows Long-lasting Remissions in Non-Hodgkin Lymphomas

Findings represent the longest follow-up data to date for a personalized cellular therapy approved by the FDA for the treatment of aggressive lymphomas. A significant number of non-Hodgkin lymphoma (NHL) patients in a Penn Medicine-initiated clinical trial continue to be in remission five years after receiving the chimeric antigen receptor […]

Study finds analyzing DNA in urine could help detect cancer

Currently, cancers are detected and diagnosed using more invasive methods such as surgical biopsies of suspected tumours and blood draws. Urinalysis has long been used to detect and manage many diseases and disorders, but not cancer. Researchers investigated whether fragments of cell-free DNA in urine could be analyzed to detect […]
