Engineer to develop a drug-filled gel to repair heart after heart attack

After a heart attack, the cells in the heart muscle cannot get enough nutrients and oxygen to survive, so they die. A structural support network in the heart’s wall can help those cells regenerate, however, two enzymes that break down the network are naturally increased after a heart attack, leaving […]

Senescence is both vital and damaging – scientists found how it works

Ageing is still not considered a disease. This is a problem, because doctors cannot prescribe known drugs that slow the ageing down, but maybe it will change with better understanding of the mechanism behind ageing. Now scientists from the University of Edinburgh found that some of the damaging cell effects […]

Against the grain

Sidney Strickland knew what he was up against when he began working on the disease more than two decades ago, and little has changed: Alzheimer’s remains a deadly health threat and among the most feared diseases on the planet, unchecked in its power to destroy brain cells and erase minds. […]

Making better embryos

One out of every six Canadian couples experiences infertility, and some resort to in vitro fertilization. Trouble is, the embryos obtained through this technique often have defects. In a study published in the journal Current Biology, researchers from the University of Montreal Hospital Research Centre (CRCHUM) succeeded in reducing the number of defects in […]

Cellular Sickness Linked to Type 1 Diabetes Onset

A UC San Francisco study of human and mouse pancreatic tissue suggests a new origin story for type 1 (T1) diabetes. The findings flip current assumptions about the causes of the disease on their head and demonstrate a promising new preventative strategy that dramatically reduced disease risk in laboratory animals.

CRISPR Gene Editing Makes Stem Cells ‘Invisible’ to Immune System

UC San Francisco scientists have used the CRISPR-Cas9 gene-editing system to create the first pluripotent stem cells that are functionally “invisible” to the immune system, a feat of biological engineering that, in laboratory studies, prevented rejection of stem cell transplants. Because these “universal” stem cells can be manufactured more efficiently […]

Old and terminally ill people do not want end-of-life care to focus on postponing death

It is something everyone will have to deal with. Our life has its beginning and it has its ending. It is not fun being aware of that, but it is the reality. End of life typically requires some sort of care. People get sick physically and mentally and cannot take […]

Engineers develop placenta-on-a-chip to study caffeine transport from mother to fetus

Engineers have used microfluidic technology to create a “placenta-on-a-chip” that models how compounds can be passed from a mother to a fetus. “I am interested in microfluidics and I’ve been excited about using the technology to understand what happens in the cellular environment and within the body,” said Nicole Hashemi, […]

Pain, fatigue, poor sleep: common symptom triad at age 65+

In older people, symptoms of pain, depression and fatigue are commonplace. But how common? Researchers examined the prevalence and impact of six common symptoms (pain, fatigue, depression, anxiety, breathing difficulty, sleep problems) and found that nearly half of adults ages 65 and older have two or more of these symptoms […]

Some Primary Care Doctors Not Prepared to Help with Cancer Treatment Decisions

The idea of team-based cancer care most often focuses on involving primary care physicians in the care of cancer survivors. But research has shown patients are discussing initial cancer treatment options with their primary care doctors. And now a new study finds that a significant number of these physicians report notable […]

Researchers push forward frontiers of vaccine science

Using sophisticated gene sequencing and computing techniques, researchers at Vanderbilt University Medical Center and the San Diego Supercomputer Center have achieved a first-of-its-kind glimpse into how the body’s immune system gears up to fight off infection. Their findings, published in the journal Nature, could aid development of “rational vaccine design,” as […]

Database funded to help researchers understand the effect of bipolar disorder throughout adult life span

Not much is known about how bipolar disorder (BD) affects people throughout their lives. Do women and men differ in the severity of their symptoms? Does a person’s age when a bipolar diagnosis is made have any bearing on how severe the symptoms are? How do other medical conditions affect […]

New insight into cell receptors opens the way for tailored cancer drugs

New research on how cancer mutations influence a certain type of receptor on the cell membrane opens the way for the development of tailored drugs for certain cancers, such as rectal cancer and lung cancer. This according to researchers at Karolinska Institutet and Uppsala University, who have been collaborating with […]

Inhibiting Cancer-Causing Protein Could Prevent Scleroderma Fibrosis

A protein known to play a role in cancer may also be increasing fibrosis in scleroderma patients. Scleroderma, a rare, chronic autoimmune disease, is marked by hardening of the skin and internal organs. Symptoms often include pain, stiffness, fatigue and breathing difficulties. “The disease creates excessive fibroblast activation that ultimately […]

Tackling Tumors That Always Come Back: New Brain Cancer Research Could Improve Outcomes

Researchers from the University of Michigan Rogel Cancer Center have found that a genetic mutation seen in about half of all brain tumors produces a response that prevents radiation treatment from working. Altering that response using FDA-approved drugs restores tumors’ sensitivity to radiation therapy, extending survival in mice. The paper, representing more […]

Researchers discover a weakness in a rare cancer that could be exploited with drugs

Cancer cells are, in some respects, impressive: They can grow relentlessly, sidestep the aging process by becoming immortal, and evade the immune system’s persistent attacks. But in the process of acquiring such superpowers, the cells must occasionally relinquish other, more mundane skills—including the ability to produce certain nutrients. Researchers at […]
