New smart drug targets and reduces site-specific inflammation

BEER-SHEVA, Israel...July 22, 2015 - Ben-Gurion University of the Negev (BGU) and University of Colorado researchers have developed a dynamic "smart" drug that targets inflammation in a site-specific manner and could enhance the body's natural ability to fight infection and reduce side effects.

Dually noted: New CRISPR-Cas9 strategy edits genes 2 ways

The CRISPR-Cas9 system has been in the limelight mainly as a revolutionary genome engineering tool used to modify specific gene sequences within the vast sea of an organism's DNA. Cas9, a naturally occurring protein in the immune system of certain bacteria, acts like a pair of molecular scissors... Read More

Felinine Plays a Role in the Chasing and Fighting between Cats and Mice

A recent study found that mice may be controlled to be brave in the fight with their biggest enemy cats after smelling a chemical emitted by them and existed in their urine. Read More

Biologist investigates how gene-swapping bacteria evade antibiotics

A scientific peek into bacteria boudoirs is revealing how "sex" among disease-causing microbes can lead different species or strains to become resistant to antibiotic medications. Read More

Sendai virus defends against a threat

A research group at Hiroshima University demonstrated the mechanism by which the Sendai virus (SeV) escapes the host immune system. The researchers examined the crystal structure of the complex of SeV C protein and transcription factor STAT1, and found that SeV C protein inhibits the signal tran... Read More

The next anti-tuberculosis drug may already be in your local pharmacy

Testing thousands of approved drugs, EPFL scientists have identified an unlikely anti-tuberculosis drug: the over-the-counter antacid lansoprazole (Prevacid®). Read More

E. coli more virulent when accompanied by beneficial bacteria

Scientists wonder why some people get so sick and even die after being infected by the foodborne pathogen E.coli O157:H7, while others experience much milder symptoms and recover relatively quickly. Now Penn State's College of Agricultural Sciences researchers believe they have discovered an exp... Read More

Transgenic pigs resistant to foot-and-mouth disease

Foot-and-mouth disease virus (FMDV) infects cloven-hoofed animals such as cattle, pigs, sheep, goats, and many wild species. The disease caused by this virus is a substantial problem for farmers because infected animals cannot be sold. Transgenic pigs have now been produced which express a short... Read More

UGA researchers develop breakthrough tools in fight against cryptosporidium

Athens, Ga. - Researchers at the University of Georgia have developed new tools to study and genetically manipulate cryptosporidium, a microscopic parasite that causes the diarrheal disease cryptosporidiosis. Their discoveries, published in the journal Nature, will ultimately help researchers in... Read More

New Diversity for Lager Beers

Washington, DC – September 25, 2015 - Unlike ales, lager beers differ little in flavor. But now, by creating new crosses among the relevant yeasts, Kevin Verstrepen, PhD, Stijn Mertens, and their collaborators have opened up new horizons of taste. The research is published in the September 25 Ap... Read More

How long have primates been infected with viruses related to HIV?

Disease-causing viruses engage their hosts in ongoing arms races: positive selection for antiviral genes increases host fitness and survival, and viruses in turn select for mutations that counteract the antiviral host factors. Studying such adaptive mutations can provide insights into the distan... Read More

Community ecology can advance the fight against infectious diseases

Despite continued medical advances, infectious diseases kill over 10 million people worldwide each year. The ecological complexity of many emerging disease threats--interactions among multiple hosts, multiple vectors and even multiple parasites--often complicates efforts aimed at controlling dis...

Cells in Senescence State May Help Slow down Aging and Cancer Treatment

BOC Sciences-Senescence means a state where cells stop further development in their function but clean themselves and remove the extra substance. Scientists found that when cells go into this stage, the growth rate of tumor would slow down, which is true of aging. The finding was made on the lev... Read More

Following Maternal Transmission, Group B Strep Mutates to Sicken Infants

Washington, DC - August 18, 2015 - Group B streptococcus, a mostly benign inhabitant of healthy adults, is one of the world’s leading causes of neonatal sepsis and meningitis. A team of French investigators has now shown that such cases might occur when the microbe mutates within the infant foll... Read More

Rapid Ebola Test Could Play Key Role in Efforts to End Lingering Outbreak

Research presented at the 2015 AACC Annual Meeting & Clinical Lab Expo will expand on the studies that led to a fingerprick Ebola test becoming the first and only rapid diagnostic for this disease to receive approval from the World Health Organization (WHO). This test could prove vital to breaki... Read More

Antiviral compound protects nonhuman primates against Marburg virus

An experimental drug that protected monkeys from the deadly Marburg virus appears to have potential for treating people who have been exposed to the virus, according to a study published in the July 23 edition of The New England Journal of Medicine. Marburg virus is closely related to Ebola viru... Read More
