2010 Dietary Guidelines urge Americans to keep calorie intake from saturated fat to less than 10%

This week the U.S. government released the 2010 Dietary Guidelines for Americans with few changes since the 2005 version. The guidelines continue to urge Americans to keep their calorie intake from saturated fat to less than 10 percent and lower the amount of trans fat in their diet to as low as possible.

Study suggests human amniotic cells 'cross talk' with melatonin receptor MT1

Human amniotic epithelial cells, stem cells derived from human placenta left over from live births and generally discarded, proliferated and differentiated when they interacted with one kind of melatonin receptor, MT1. This potentially therapeutic response occurred when the stem cells were transplanted into laboratory test tube and animal models of stroke. The same cells did not perform similarly when interacting with melatonin receptor MT2.

Targeted delivery combination crosses brain protecting barrier and homes in on tumors

A targeted delivery combination selectively crosses the tight barrier that protects the brain from the bloodstream to home in on and bind to brain tumors, a research team led by scientists from The University of Texas MD Anderson Cancer Center reported in the January issue of the Journal of Clinical Investigation.

Nitrate boosts efficiency of mitochondria

The spinach-eating cartoon character Popeye has much to teach us, new research from the Swedish medical university Karolinska Institutet shows. The muscles' cellular power plants - the mitochondria - are boosted by nitrate, a substance found in abundance in vegetables such as lettuce, spinach and beetroot.

Multi-national group of researchers announce launch of International Genomics of Alzheimer's Project

The launch of the International Genomics of Alzheimer's Project (IGAP) - a collaboration formed to discover and map the genes that contribute to Alzheimer's disease - was announced today by a multi-national group of researchers including Drs. Lindsay Farrer and Sudha Seshadri at Boston University School of Medicine (BUSM). The collaborative effort, spanning universities from both sides of the Atlantic, will combine the knowledge, staff and resources of four consortia that work on Alzheimer's disease genetics.

Nanotechnology and nanotoxicology

The rapid development of nanotechnology has increased fears about the health risks of nano-objects. Are these fears justified? Do we need a new discipline, nanotoxicology, to evaluate the risks? Empa scientists Harald F. Krug and Peter Wick discuss these questions in the new edition of the journal Angewandte Chemie.

Higher intake of monounsaturated, polyunsaturated fatty acids reduce risk of mild cognitive impairment

Mayo Clinic researchers found that the prevalence of mild cognitive impairment decreased with an increase in the consumption of monounsaturated and polyunsaturated fatty acids. Monounsaturated fatty acids are commonly found in olive oil and canola oils, and polyunsaturated fatty acids, such as Omega 3 or Omega 6 fatty acids, are commonly found in most varieties of nuts, seeds and fish.

Zebrafish research findings may provide potential to improve kidney function in humans

It is estimated that up to 10 percent of the U.S. population may have some form of renal disease, with 450,000 patients with end stage renal disease requiring hemodialysis. Researchers at Brigham and Women's Hospital, Massachusetts General Hospital and the University of Pittsburgh have identified a cell in zebrafish that can be transplanted from one fish to another to regenerate nephrons, providing the potential to improve kidney function.

First commercially available full length human MTOR protein with superior biological activity released

OriGene Technologies, Inc., a gene-centric life sciences company, releases the first commercially available full length human MTOR protein with superior biological activity.

Defective nucleoli linked to Parkinson's disease

"Nucleolus", or small nucleus, is the term coined by early biologists for the tiny structure within the nucleus which they saw under the microscope. In this structure within the nucleus, RNA molecules and proteins are assembled to form ribosomes, the true protein factories of cells.

Drugs affecting brain noradrenaline levels could improve breathing in sleep apnea patients

New research from the University of Toronto could provide some restful nights for the 18 million North Americans who suffer from obstructive sleep apnea.

Researchers find better way to create iPS cells from blood samples

Researchers at Johns Hopkins have found a better way to create induced pluripotent stem cells-adult cells reprogrammed with the properties of embryonic stem cells-from a small blood sample. This new method, described last week in Cell Research, avoids creating DNA changes that could lead to tumor formation.

Microbubble contrast- enhanced ultrasound improves identification of sentinel lymph node in breast biopsies

Using "microbubbles" and ultrasound can mean more targeted breast biopsies for patients with early breast cancer, helping to determine treatment and possibly saving those patients from undergoing a second breast cancer surgery, a new study in shows.

Study finds treatment-related mortality with bevacizumab in cancer patients

Cancer patients treated with the chemotherapy agent bevacizumab may be at an increased risk of treatment-related death when the drug is used in combination with other therapies.

Bioengineers and physician-scientists zap tumors with light-activated nanoparticles

Rice University bioengineers and physician-scientists at Baylor College of Medicine and Texas Children's Hospital have successfully destroyed tumors of human brain cancer cells in the first animal tests of a minimally invasive treatment that zaps glioma tumors with heat. The tests involved nanoshells, light-activated nanoparticles that are designed to destroy tumors with heat and avoid the unwanted side effects of drug and radiation therapies.

Scientists discover breast cancer cells that dodge immune system, promote tumor growth

Scientists discovered a new way breast cancer cells dodge the immune system and promote tumor growth, providing a fresh treatment target in the fight against the disease. While comparable mechanisms to avoid the immune system have been identified in mice with breast and other cancers, the study tested human breast tumor cells, putting researchers closer to understanding how the disease progresses in real patients.

Scientists test new dry powder measles vaccine that can be inhaled

Sustained high vaccination coverage is key to preventing deaths from measles. Despite the availability of a vaccine, measles remains an important killer of children worldwide, particularly in less-developed regions where vaccination coverage is limited. A team of researchers, led by scientists at the Johns Hopkins Bloomberg School of Public Health and the University of Colorado, developed and successfully tested a dry powder, live-attenuated measles vaccine that can be inhaled.
