Bone marrow cell transplants to benefit those with heart disease
Separate bone marrow cell transplantation studies may lead to new treatments for the treatment of heart diseases. One study by a team of Brazilian researchers, found that cell transplantation of bone marrow mononuclear cells (BMMCs) and ReACT formula injected directly into the heart benefited patients suffering from refractory angina. A second study in the Peoples' Republic of China found that apelin, a newly described inotropic peptide, improves heart function following transplantation of BMMCs.

Pandemic Hybrid Of Bird And Human Seasonal Flu Possible Say Scientists

An international team of scientists has created a highly pathogenic laboratory hybrid of the H5N1 bird flu and human seasonal flu viruses by swapping just one gene, and propose that a similar genetic interaction could happen in nature between the current pandemic H1N1 swine flu and H5N1 avian flu strains, highlighting the importance of continued surveillance. A report of the study by senior author is Dr Yoshihiro Kawaoka, professor of pathobiological sciences in the School of Veterinary Medicine at the University of Wisconsin-Madison in the US, and colleagues, appeared online before print on 22 February in the Proceedings of the National Academy of Sciences, PNAS.

57 Million Americans Are On The Brink Of Getting Diabetes: A Convenient Lab Test Can Help Pull Them Back

Approximately 57 million Americans are on the brink of diabetes . Yet research tells us that there is much we can do to keep it from progressing to full-blown diabetes. Lab tests can help us get a grip on the disease, says the American Clinical Laboratory Association President Alan Mertz. "Ask your doctor about a quick and easy lab test called hemoglobin A1C (A1C). The test can tell you if you actually have diabetes or are close to developing it a silent and serious condition called pre-diabetes," says Mertz.

Predicting The Progression Of Alzheimer's

An assessment has been developed which reliably predicts future performance in cognition and activities of daily living for patients withAlzheimer's disease . Researchers writing in BioMed Central's open access journal Alzheimer's Research & Therapy followed 597 patients over 15 years to identify factors associated with slow, intermediate and rapid progression. Professor Rachelle Doody worked with a team of researchers from Baylor College of Medicine, Texas, US, to carry out the study. She said, "Patients and families frequently ask clinicians to predict expected rates of cognitive and functional decline, and clinicians currently have little basis for making such decisions. We've found that a simple, calculated progression rate at the initial visit gives reliable information regarding performance over time. The slowest progression group also survives longer."

Ultra-Fast Lasers Open Doors To New Technologies Unheard Of Just Years Ago

For nearly half a century, scientists have been trying to figure out how to build a cost-effective and reasonably sized X-ray laser that could, among other things, provide super high-resolution imaging. And for the past two decades, University of Colorado at Boulder physics professors Margaret Murnane and Henry Kapteyn have been inching closer to that goal. Recent breakthroughs by their team at JILA, a joint institute of CU-Boulder and the National Institute of Standards and Technology, have paved the way on how to build a tabletop X-ray laser that could be used for super high-resolution imaging, while also giving scientists a new way to peer into a single cell and gain a better understanding of the nanoworld.

How nerve cells grow
Brain researcher Hiroshi Kawabe has discovered the workings of a process that had been completely overlooked until now, and that allows nerve cells in the brain to grow and form complex networks. The study shows that an enzyme which usually controls the destruction of protein components has an unexpected function in nerve cells: it controls the structure of the cytoskeleton and thus ensures that nerve cells can form the tree-like extensions that are necessary for signal transmission in the brain.

Chemical tags likely to affect metabolism, cancer development
Research from the University of North Carolina at Chapel Hill suggests that the addition or removal of a certain type of chemical tag -- called an acetyl group -- onto metabolic enzymes plays a key role in how cellular metabolism is regulated. The finding gives researchers vital clues to understand how normal cells respond to nutrient changes and how the process by which normal cells turn cancerous, and could one day lead to new drugs that starve cancer cells into submission.

Phase II HIV Gene Therapy Trial Data At CROI 2010 Presented By Penn Researchers

Researchers from the University of Pennsylvania School of Medicine presented the results from an ongoing Phase I/II open-label clinical trial of Lexgenleucel-T at the 16th Conference on Retroviruses and Opportunistic Infections (CROI) in San Francisco, CA. Lexgenleucel-T is a cell and gene therapy product being investigated for the treatment of HIV infection. The current study examined the effect of Lexgenleucel-T infusions in HIV-1 infected individuals prior to being taken off their antiretroviral treatment (HAART) regimens as part of the study design's scheduled treatment interruption. In the study, seven of eight evaluable subjects experienced a decrease in viral load set point and one subject experienced prolonged, complete control of HIV viremia for more than 14 weeks in the absence of HAART. Viral load set point is the HIV RNA value specific for each infected individual in absence of anti-retroviral drug control. Higher viral load set point is correlated with more rapid disease progression to AIDS . "We are excited to see these responses using autologous transfer of CD4+ T lymphocytes genetically modified with VRX496TM, a HIV-based lentiviral vector encoding for a RNA antisense targeting HIV env. These are subjects who were taken off of their antiretroviral treatment and are showing a better control of their infection as demonstrated by reduced viral load set points," said Pablo Tebas, M.D., director of the Adult AIDS Clinical Trials Unit, who presented the results at CROI. "Further study is needed to see whether these types of results will translate into a delay in disease progression."

Pittsburgh Neurosurgeons Explore Use Of Drug That Illuminates Brain Tumor Cells To Guide Surgery

AGH is one of just three medical centers in the country approved by the U.S. Food and Drug Administration to investigate the efficacy of an oral fluorescent compound, called 5-aminoevulnic acid (ALA), in a clinical trial of patients diagnosed with a glioma, the most common form of primary brain tumor.
