World’s first demonstration of multicolor 3-D in vivo imaging using ultra-compact Compton camera with dramatically reduced measurement time As represented by conventional radiograph, radiological images provide only black and white figures in 2D space. The situation is basically the same for Single photon emission tomography (SPECT) and positron emission tomography (PET), which are the two...

Dehydration headaches: Signs, treatment, and prevention
Headaches are one of the most common causes of pain and missed days of work. But what are the key signs that a headache might be due to dehydration? There are many different kinds of headaches and 9 out of 10 adults will experience one at some point in their life. Some of the different kind of headaches,...

Diagnosis and treatment for ankylosing spondylitis
Ankylosing spondylitis is a disorder that causes chronic pain in the joints, usually starting in the back and buttocks. There are a few steps to diagnosing ankylosing spondylitis (AS), as well as some early signs that people should be aware of. People also need to understand how diagnoses can vary, and what sort of treatment they...

Effects of diabetes on the body and organs
Over time, the raised blood sugar levels that result from diabetes can cause a wide range of serious health issues. But what do these health issues involve, and how are the organs of the body affected? Can these effects be minimized? When people have diabetes, the body either does not make enough insulin or cannot use what...

Team discovers neural stem cells can become blood vessels
Professor Ricardo Pardal and his team. Mother cells from the adult carotid body can transform into blood vessels as well as neurons. This discovery could have important repercussions on the treatment of such diseases as pediatric tumors and Parkinson’s. Researchers from the University of Seville and the Seville Institute of Biomedicine (IBiS) have just...

Repeated Administrations of Stem Cells are More Effective than Single Administration
After a heart attack, the heart can undergo several structural and functional changes. Even after oxygen delivery to the heart muscle has been restored, a temporary loss of contractile function can persist for several hours or even days. This phenomenon is called myocardial stunning and it can also occur in people who have undergone cardiovascular...

Stem cell transplants may advance ALS treatment by repair of blood-spinal cord barrier
Researchers at the University of South Florida show in a new study that bone marrow stem cell transplants helped improve motor functions and nervous system conditions in mice with the disease Amyotrophic Lateral Sclerosis (ALS) by repairing damage to the blood-spinal cord barrier. In a study recently published in the journal Scientific Reports, researchers in USF’s...

Researchers identify ‘signal’ crucial to stem cell function in hair follicles
Jeff Biernaskie’s research identifies a factor essential for dermal stem cells to continuously divide during tissue regeneration. Stem cell researchers at the University of Calgary have found another piece of the puzzle behind what may contribute to hair loss and prevent wounds from healing normally. Jeff Biernaskie’s research, published recently in the scientific journal npj...

Success of stem cell therapy for diabetes depends on pre-transplant immune condition
An innovative method for treating type 1 diabetes based on the transplantation of hematopoietic stem cells taken from the patient’s own bone marrow began undergoing testing in Brazil 13 years ago. The results were highly variable. While some of the volunteers were able to stop self-injecting insulin for more than a decade, others had to...

Injured bones reconstructed by gene and stem cell therapies
This illustration shows the bone-tissue engineering technique developed by Cedars-Sinai investigators. ‘Endogenous MSCs’ refers to stem cells from a patient’s bone. The ‘BMP gene’ is a gene that promotes bone repair. A Cedars-Sinai-led team of investigators has successfully repaired severe limb fractures in laboratory animals with an innovative technique that cues bone to regrow...
