Simple gene-based blood test, quicker, more accurate evaluation for cystic fibrosis

Researchers at National Jewish Health have identified a simple gene-based blood test that more accurately and quickly measures cystic fibrosis patients' response to therapy than current tests.

Molecule stops DNA replication in its tracks

When a dividing cell duplicates its genetic material, a molecular machine called a sliding clamp travels along the DNA double helix, tethering the proteins that perform the replication.

New test for rapid detection of influenza

The Association of Public Health Laboratories (APHL) collaborated with the Centers for Disease Control and Prevention (CDC) in the development of a new test for influenza, which received 510(k) clearance today by the Food and Drug Administration (FDA).

Micronics receives two new patents on microfluidic technologies

Micronics, Inc. today announced that it has been issued two patents from the United States Patent and Trademark Office (USPTO) for novel microfluidic devices and methods. These new patents relate to the company’s focus on the development of rapid and easy to use clinical diagnostic products.

Premature births may be the result of undiagnosed infection

Scientists in the U.S. say a significant number of premature births may be caused by infections which are undiagnosed and the heavier the infection, the more likely the women were to deliver younger, sicker babies.

Infections of amniotic fluid may be a significant cause of premature birth

Previously unrecognized and unidentified infections of amniotic fluid may be a significant cause of premature birth, according to researchers at the Stanford University School of Medicine.

Rifamycin antibiotics attack tuberculosis bacteria with walls, not signals

Amid concerns about the rising number of new tuberculosis cases worldwide, researchers led by Rockefeller University's Seth A. Darst have reexamined and disproved a theory that describes how a potent class of antibiotics kills a deadly form of bacteria. The findings, which will appear in this week's online issue of the Proceedings of the National Academy of Sciences, not only bring scientists closer to understanding how these antibiotics work but also how the bacteria become resistant to their effects.

New studies examine use of the nucleoside polymerase inhibitor, R1626, to the standard therapy for hepatitis C

Two new studies examine the use of the nucleoside polymerase inhibitor, R1626, to the standard therapy for hepatitis C. The reports appear in the August issue of Hepatology, a journal published by John Wiley & Sons on behalf of the American Association for the Study of Liver Diseases (AASLD).

New biomarker for early cancer detection? Research reveals that 'microRNA' may fit the bill

Scientists at Fred Hutchinson Cancer Research Center have discovered that microRNAs - molecular workhorses that regulate gene expression - are released by cancer cells and circulate in the blood, which gives them the potential to become a new class of biomarkers to detect cancer at its earliest stages. Muneesh Tewari, M.D., Ph.D., and colleagues describe their findings in the July 28 issue of the Proceedings of the National Academy of Sciences.

Cure for bird flu a step closer

Scientists and researchers have taken a big step closer to a cure for the most common strain of avian influenza, or "bird flu," the potential pandemic that has claimed more than 200 lives and infected nearly 400 people in 14 countries since it was identified in 2003.

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.

Disease-detecting lab-on-a-chip

Detecting food-borne diseases such as campylobacter and salmonella long before they enter the food chain would help ensure that the dinner on your table is safe to eat.

NCI scientists visualize gene regulation in living cells

A research team led by scientists at the National Cancer Institute (NCI), part of the National Institutes of Health (NIH), has applied advanced imaging methods and computer simulations to be able to glance at the regulation of a cancer-related gene in a living cell. They found that the efficiency with which the components of the cell's gene reading machinery come together has an impact on gene expression, the process by which a gene translates its information into a new protein. The findings, published in the May 23, 2008 issue of Molecular Cell, shed new light on the means by which living cells regulate gene activity.

Scientists identify key roadblock to gene expression

A team of scientists has provided, for the first time, a detailed map of how the building blocks of chromosomes, the cellular structures that contain genes, are organized in the fruit fly Drosophila melanogaster. The work identifies a critical stop sign for transcription, the first step in gene expression, and has implications for understanding how the AIDS virus regulates its genes. The findings will be published in the 15 May 2008 issue of the journal Nature

Clockwork PCR including sample prep

Analysis and diagnosis in a chip format are coming of age, but their practical application has been limited because until now, the sample usually had to be prepared separately and on a nonminiaturized scale.

Cancer could return unless stored ovarian tissue undergoes adequate testing before re-implantation

Cancer patients who have been successfully treated for their disease face the prospect of its return if stored ovarian (or testicular) tissue is transplanted back into their bodies without adequate checks, according to researchers at two university hospitals in Israel.

Periodontitis and human papillomavirus combined increase risk for tongue cancer

Persons with periodontitis who also are infected with human papillomavirus (HPV) are at increased risk of developing tongue cancer, new research conducted at the University at Buffalo School of Dental Medicine has shown.

MRSA in hospital intensive care -- what's growing where?

Researchers are finding out which bugs grow in intensive care units to develop a novel sampling regime that would indicate the threat of MRSA and other superbugs in the environment, scientists heard (Monday 31 March 2008) at the Society for General Microbiology's 162nd meeting being held this week at the Edinburgh International Conference Centre.

A biosensing nanodevice to revolutionize health screenings

One day soon a biosensing nanodevice developed by Arizona State University researcher Wayne Frasch may eliminate long lines at airport security checkpoints and revolutionize health screenings for diseases like anthrax, cancer and antibiotic resistant Staphylococcus aureus (MRSA).

BARACLUDE data show low resistance over 5 years in nucleoside-naive hepatitis B patients

New BARACLUDE (entecavir) data presented demonstrated a continued low incidence of resistance in nucleoside-naïve patients through five years of treatment. In the nucleoside-naïve chronic hepatitis B patients analyzed, no additional patient developed resistance in the fifth year (n=108).
