Compound honokiol, from Magnolias blocks, elusive pathway for cancer growth

A natural compound from magnolia cones blocks a pathway for cancer growth that was previously considered "undruggable," researchers have found.

Researches identify herpesvirus proteins that target key cellular processes

A study published July 11th in the open-access journal PLoS Pathogens suggests that herpesviruses use multiple strategies to manipulate important components of the host cell nuclear environment during infection.

Scientists mimic molecules to protect against plague

Bacteria that cause pneumonic plague can evade our first-line defences, making it difficult for the body to fight infection. In fact, a signature of the plague is the lack of an inflammatory response. Now, scientists have discovered a way to protect against death following infection with plague bacteria, by using molecules that can mimic the pathogens. According to research published in the July issue of Microbiology, these molecules make antibiotics more effective and can even be used to protect against other diseases.

Stem cells help keep the brain healthy and active

For some years, scientists have been speculating over why stem cells exist in the brain, as brain regeneration is limited. A German team of neuroscientists believe these stem cells help keep the brain healthy and active.

URMC, FDA to collaborate on national data repository for heart research

The University of Rochester Medical Center (URMC) will collaborate with the U.S. Food and Drug Administration (FDA) to develop a national repository of data that will aid academic and industry researchers studying the electrical activity of the heart. In addition to helping researchers understand many cardiac problems, the data may aid the development of new tools to detect drugs that can have dangerous effects on the heart.

Researchers find six genes that, when mutated, contribute to autism

The hunt for gene mutations that contribute to autism has proceeded slowly, largely because autism encompasses a spectrum of diseases. Just as its symptoms vary widely among individuals, so do the genetic mutations that cause them.

Proof-of-concept that purified muscle stem cells can be used in therapy

By injecting purified stem cells isolated from adult skeletal muscle, researchers have shown they can restore healthy muscle and improve muscle function in mice with a form of muscular dystrophy. Those muscle-building stem cells were derived from a larger pool of so-called satellite cells that normally associate with mature muscle fibers and play a role in muscle growth and repair.

Researchers discover that learning suffers if brain transcript isn't transported far out to end of neurons

Neuroscientists at Georgetown University Medical Center have solved a mystery that lies at the heart of human learning, and they say the solution may help explain some forms of mental retardation as well as provide clues to overall brain functioning.

Researchers identify brain cells related to fear - paves way for more effective PTSD treatments

The National Institute of Mental Health estimates that in any given year, about 40 million adults (18 or older) will suffer from some form of anxiety disorder, including debilitating conditions such as phobias, panic disorders and post-traumatic stress disorder (PTSD). It is estimated that nearly 15 percent of U.S. soldiers returning from Iraq and Afghanistan develop PTSD, underscoring the urgency to develop better treatment strategies for anxiety disorders.

Scientists identify 22 genes that control embryonic stem cell fate

Scientists have identified about two dozen genes that control embryonic stem cell fate. The genes may either prod or restrain stem cells from drifting into a kind of limbo, they suspect. The limbo lies between the embryonic stage and fully differentiated, or specialized, cells, such as bone, muscle or fat.

Australian naturopaths in favour of regulation

Naturopaths are strongly in favour of regulation of their industry, a University of Queensland researcher has found.

Advances in RNA research

RNA, the transporter of genetic information within the cell, has emerged from the shadow of DNA to become one of the hottest research areas of molecular biology, with implications for many diseases as well as understanding of evolution. But the field is complex, requiring access to the latest equipment and techniques of imaging, gene expression analysis and bioinformatics, as well as cross-pollination between multiple scientific disciplines.

Researchers measure movements smaller than one-billionth of a meter in ion channels

Each thought or action sends a million electrical signals pulsing through your body. At the heart of the process of generating these electrical impulses is the ion channel.

UGA discovery could lead to new ways to attack cancers by blocking their ability to grow

Human cancer cells divide and conquer. Unless physicians can control that division with surgery, chemotherapy or radiation, the wildly dividing cells will eventually destroy a person's life.

Novel approach shows potential to become an emergency treatment for heart attack patients

Researchers at The Children's Hospital of Philadelphia have manipulated cell activity that occurs during the interruption of blood flow to strongly protect heart tissue in animal studies. The finding has the potential to become an emergency treatment for heart attack patients, particularly since already existing drugs might be pressed into service to produce the protective effects.

More research needed into effects of flavonoids and flavonoid-rich food sources on heart disease

More research is needed into food compounds which could reduce the risk of heart disease, according to a systematic review of trials carried out so far.

Heat waves when in hospital

Deaths due to high temperatures occur so quickly that patients do not have time to be admitted to hospital. This is why prevention campaigns are necessary to try and reduce the negative effects of the heat on health. This is pointed out in new research undertaken at the Hospital Universitario Gregorio Maranon, Madrid.

Researchers crack final part of the immune system code

A group of researchers at the Technical University of Denmark and the University of Copenhagen have developed models of neural networks that make it possible to simulate how the body protects itself from disease and predict the immune system's access codes.

Researcher develops method for early detection of leukemia relapse

Researchers at the Fred Hutchinson Cancer Research Center have developed a method that allows for the early detection of a common mechanism of resistance on drug treatment for chronic myeloid leukemia.
