Omega-3 fatty acids especially DHA may have even wider range of biological impacts, shows study

Omega-3 fatty acids especially DHA may have even wider range of biological impacts, shows study

A study of the metabolic effects of omega-3 fatty acids, especially DHA, concludes that these compounds may have an even wider range of biological impacts than previously considered, and suggests they could be of significant value in the prevention of fatty liver disease. [More]
Researchers test role of dietary supplement use in college students

Researchers test role of dietary supplement use in college students

Habits acquired during young adulthood are crucial in fostering lifelong health. Unfortunately, some college students fall into nutrient-deficient diets that leave them at risk for developing chronic disease later in life. [More]
Researchers discover mechanism that controls activity of LRRK2 in Parkinson's disease

Researchers discover mechanism that controls activity of LRRK2 in Parkinson's disease

In one variant of Parkinson's disease, the enzyme LRRK2 plays a central role. Scientists at the University of Kassel have now discovered a mechanism that controls the activity of LRRK2. [More]
Researchers identify five new genes associated with increased waist-to-hip ratio

Researchers identify five new genes associated with increased waist-to-hip ratio

Excess abdominal fat can be a precursor to diseases such as cardiovascular disease, type 2 diabetes and cancer. A person's measure of belly fat is reflected in the ratio of waist circumference to hip circumference, and it is estimated that genetics account for about 30-60 percent of waist-to-hip ratio. [More]
Scientists discover novel mechanism that influences GAS virulence at early steps of necrotizing fasciitis

Scientists discover novel mechanism that influences GAS virulence at early steps of necrotizing fasciitis

How does Streptococcus pyogenes, or Group A streptococcus (GAS) — a bacterial pathogen that can colonize humans without causing symptoms or can lead to mild infections — also cause life-threatening diseases such as necrotizing fasciitis (commonly known as flesh-eating disease) and streptococcal toxic shock syndrome? [More]

Research may lead to potential treatment for deadly bacterial infections

Collaboration between the National University of Singapore (NUS) and The Hebrew University of Jerusalem (HUJ) on inflammation research may lead to a potential treatment for deadly bacterial infections [More]

Research opens way to possible new treatments for bacterial infections

​How does Streptococcus pyogenes, or Group A streptococcus (GAS) - a bacterial pathogen that can colonize humans without causing symptoms or can lead to mild infections - also cause life-threatening diseases such as necrotizing fasciitis (commonly known as flesh-eating disease) and streptococcal toxic shock syndrome?

Researchers discover two genetic mutations associated with Familial Alzheimer's Disease

Researchers discover two genetic mutations associated with Familial Alzheimer's Disease

New research, led by Rensselaer Polytechnic Institute researcher Chunyu Wang, has solved one mystery in the development of Familial Alzheimer's Disease (FAD), a genetic variant of the disease that affects a small fraction of the Alzheimer's population. In a paper published online January 6 in the journal Nature Communications, Wang and his team follow the trail of two genetic mutations - V44M and V44A - known to cause FAD, and show how the mutations lead to biochemical changes long linked to the disease.

Study compares relative rate of molecular evolution between humans and chimps with their lice

A new study compares the relative rate of molecular evolution between humans and chimps with that of their lice. The researchers wanted to know whether evolution marches on at a steady pace in all creatures or if subtle changes in genes - substitutions of individual letters of the genetic code - occur more rapidly in some groups than in others.

Inflammatory burden increased in overweight bipolar disorder patients

Inflammatory burden increased in overweight bipolar disorder patients

Breakdown of the amino acid tryptophan is increased in euthymic, overweight individuals with bipolar disorder, show preliminary results from the BIPFAT study. [More]
Researchers make new breakthrough in HIV vaccine research

Researchers make new breakthrough in HIV vaccine research

A vaccine study in monkeys designed to identify measurable signs that the animals were protected from infection by SIV, the monkey version of HIV, as well as the mechanism of such protection has yielded numerous insights that may advance HIV vaccine research. [More]

Researchers receive Doris Duke Foundation award to predict sickle cell crisis, monitor treatments

Researchers at Case Western Reserve University have received a $486,000 Doris Duke Foundation award to discover how to predict when sickle cell disease patients will suffer an acute crisis and monitor the effectiveness of treatments. [More]
Researchers discover molecular "switch" in receptor that controls cell behavior

Researchers discover molecular "switch" in receptor that controls cell behavior

If scientists can control cellular functions such as movement and development, they can cripple cells and pathogens that are causing disease in the body. [More]
Utah researchers discover naturally occurring genetic variation that cause inflammatory arthritis

Utah researchers discover naturally occurring genetic variation that cause inflammatory arthritis

University of Utah researchers have discovered a naturally occurring genetic variation in mice that predisposes carriers toward developing severe, inflammatory arthritis. The finding implicates a new class of genes in arthritis progression, potentially opening doors to new treatment options. [More]

University of Colorado medical school professor uncovers variant of NKH

People from around the country and the world turn to Johan Van Hove, MD, PhD, for advice on a rare metabolic disease known as NKH, which can disrupt the body in devastating and even deadly ways. Now, Van Hove, a University of Colorado medical school professor, has identified a new disease related to NKH, a finding that resolves previously baffling cases including the death of a Colorado girl.

Probe mimics pathogen's amino acids, solving mystery behind Chlamydiae cell wall

Probe mimics pathogen's amino acids, solving mystery behind Chlamydiae cell wall

​Biochemical sleuthing by an Indiana University graduate student has ended a nearly 50-year-old search to find a megamolecule in bacterial cell walls commonly used as a target for antibiotics, but whose presence had never been identified in the bacterium responsible for the most commonly reported sexually transmitted disease in the United States.

Researchers find how olfactory receptor variation impacts human odor perception

Researchers find how olfactory receptor variation impacts human odor perception

According to Gertrude Stein, "A rose is a rose is a rose," but new research indicates that might not be the case when it comes to the rose's scent. Researchers from the Monell Center and collaborating institutions have found that as much as 30 percent of the large array of human olfactory receptor differs between any two individuals. This substantial variation is in turn reflected by variability in how each person perceives odors. [More]
New research finds that H7N9 still mainly adapted for infecting birds, not humans

New research finds that H7N9 still mainly adapted for infecting birds, not humans

Avian influenza virus H7N9, which killed several dozen people in China earlier this year, has not yet acquired the changes needed to infect humans easily, according to a new study by scientists at The Scripps Research Institute. In contrast to some initial studies that had suggested that H7N9 poses an imminent risk of a global pandemic, the new research found, based on analyses of virus samples from the Chinese outbreak, that H7N9 is still mainly adapted for infecting birds, not humans.
