New genes that regulate longevity

In an effort to understand the molecular mechanisms that control aging, Howard Hughes Medical Institute researchers and their colleagues have now uncovered 10 new genes that regulate longevity in yeast. The studies also suggest a new model for how aging is slowed when caloric intake is restricted.

Possible viral cause of Kawasaki disease identified

In an important discovery in infectious disease research, a team of scientists from Northwestern University has identified a possible viral cause of Kawasaki disease, the most common cause of acquired heart disease in children in developed nations.

Mayo Clinic provides new strategy for designing better treatments for juvenile dermatomyositis

Mayo Clinic researchers, working with colleagues at the University of Minnesota and University of Pittsburgh, are the first to describe a new role for a specialized cell of the immune system in children suffering from a rare muscle-damaging disease known as juvenile dermatomyositis (JDM).

Link between diet and epileptic seizures studied

Although the high-fat, calorie-restricted ketogenic diet (KD) has long been used to prevent childhood epileptic seizures that are unresponsive to drugs, physicians have not really understood exactly why the diet works.

New Flu Chip can determine the genetic make-up of types of flu virus in 11 hours

A novel "Flu Chip" developed at the University of Colorado at Boulder that can determine the genetic signatures of specific influenza strains from patient samples within hours may help world health officials combat coming epidemics and pandemics.

New high-resolution data on intact ribosome

A new, sharper picture of the nano-machine that translates our genetic program into proteins promises to help researchers explain how some types of antibiotics work and could lead to the design of better ones.

Rapid screen-and-treat methods significantly reduce cervical cancer precursor lesions

A new study led by Columbia University Medical Center researchers demonstrates the safety and efficacy of two low-tech diagnostic tools to significantly reduce the prevalence of cervical cancer precursor lesions.

Targeted drug delivery now possible using nanoparticle-apatamer conjugates

Ground-breaking results from researchers at Harvard Medical School and Massachusetts Institute of Technology (MIT), USA, disclosed at the 13th European Cancer Conference (ECCO) have shown for the first time that targeted drug delivery is possible using nanoparticle-apatamer conjugates.

Possible toxic damage from inhaled nanoparticles

A physicist and a medical researcher at the University of Leicester have received a grant of £100,000 from the Engineering and Physical Sciences Research Council to look at possible toxic damage from inhaled nanoparticles used for a range of everyday purposes.

Number of color-sensitive cones in the human retina differs dramatically among people

First-ever images of living human retinas have yielded a surprise about how we perceive our world.

New model important step toward understanding the molecular basis of cell membrane mechanics

A human red blood cell is a dimpled ballerina, ceaselessly spinning, tumbling, bending, and squeezing through openings narrower than its width to dispense life-giving oxygen to every corner of the body.

Scientists discover molecular structure related to cell growth and cancer

Researchers discovered a special type of molecular structure that helps keep genes properly turned off until the structure is ejected from those genes in a regulated manner to help turn the genes on.

Method to count the absolute number of individual protein molecules inside a living cell

Yale researchers have reported a method to count the absolute number of individual protein molecules inside a living cell, and to measure accurately where they are located, two basic hurdles for studying biology quantitatively.

New prostate cancer test far more accurate

At present in order to predict prostate cancer outcomes, doctors rely on measures that suggest how far the tumour has spread and how abnormal the cancer cells appear under the microscope.

18 Oct 2005

New findings on brain tumors called ependymomas

Brain tumors called ependymomas that occur in different parts of the central nervous system appear to arise from subpopulations of stem cells called radial glia cells (RGCs), according to investigators at St. Jude Children's Research Hospital. The discovery explains why some identical-looking ependymomas are actually distinctly different diseases, the researchers said.

Curry spice appears to shut down a protein active in the spread of breast cancer

Curcumin, the main ingredient of turmeric and the compound that gives curry its mustard-yellow color, inhibits metastasis to the lungs of mice with breast cancer, report researchers at The University of Texas M. D. Anderson Cancer Center

Performing a sentinel node biopsy prior to mastectomy and reconstruction gives best results

Altering the standard step-by-step procedure that takes women facing a mastectomy from diagnosis to surgery to reconstruction can improve the process and help in determining if immediate reconstruction is the best course of action, according to new research from the University of North Carolina at Chapel Hill.

New insights that advance the current model of protein motility and muscle contraction

Scientists from the Burnham Institute for Medical Research and the University of Vermont have captured the first 3-dimensional (3D) atomic-resolution images of the motor protein myosin V as it "walks" along other proteins, revealing new structural insights that advance the current model of protein motility and muscle contraction.
