Loss of dietary diversity contributes to rise in obesity, Type 2 diabetes and other diseases

A loss of dietary diversity during the past 50 years could be a contributing factor to the rise in obesity, Type 2 diabetes, gastrointestinal problems and other diseases, according to a lecture by Mark Heiman, vice president and chief scientific officer at MicroBiome Therapeutics, at IFT15: Where Science Feeds Innovation hosted by the Institute of Food Technologists in Chicago.

Nitric oxide released through nanotechnology may be a new way to treat, prevent acne

GW researcher and dermatologist, Adam Friedman, M.D., and colleagues, find that the release of nitric oxide over time may be a new way to treat and prevent acne through nanotechnology.

New hand-held paper machine could be used for point-of-care detection of infectious diseases, cancer

In the U.S. and other industrialized nations, testing for infectious diseases and cancer often requires expensive equipment and highly trained specialists. In countries where resources are limited, performing the same diagnostics is far more challenging. To address this disparity, scientists are developing a portable, low-cost "paper machine" for point-of-care detection of infectious diseases, genetic conditions and cancer.

Magnetic nanoparticles may hold key to bringing immunotherapy into successful clinical use

In recent years, researchers have hotly pursued immunotherapy, a promising form of treatment that relies on harnessing and training the body's own immune system to better fight cancer and infection. Now, results of a study led by Johns Hopkins investigators suggests that a device composed of a magnetic column paired with custom-made magnetic nanoparticles may hold a key to bringing immunotherapy into widespread and successful clinical use.

Survey: Over 30% of parents say their children missed school due to oral health problem

This past school year was a painful one for many U.S. students, according to a new survey out today from Delta Dental. The survey finds that more than 30 percent of parents said their children between the ages of six and 12 had to miss school due to an oral health problem.

Scientists discover new variant of streptococcal bacteria that contributes to severe infections

Scientists have discovered a new variant of streptococcal bacteria that has contributed to a rise in disease cases in the UK over the last 17 years.

New study highlights burden of community-acquired pneumonia hospitalizations among U.S. adults

Viruses, not bacteria, are the most commonly detected respiratory pathogens in U.S. adults hospitalized with pneumonia, according to a New England Journal of Medicine study released today and conducted by researchers at Centers for Disease Control and Prevention and hospitals in Chicago and Nashville, including Vanderbilt University Medical Center.

Multidrug-resistant bacteria can naturally relinquish its ability to resist antibiotics

Infections with one of the most troublesome and least understood antibiotic-resistant "superbugs" are increasing at alarming rates, particularly in health-care settings.

New approach provides more complete picture of donor support for key global health issues

As the world's leaders gather in Addis Ababa, Ethiopia, for the Financing for Development Conference, a study published in The Lancet demonstrates that a new approach is needed for classifying funding that reflects the function the funding serves, rather than the specific disease or country. The study is the first in-depth assessment of how donor funding is spent on global versus country-specific functions of health.

Researchers identify protein responsible for preserving antibody-producing cells that lead to long-term immunity

Melbourne researchers have identified a protein responsible for preserving the antibody-producing cells that lead to long-term immunity after infection or vaccination.

Laser microdissection microscope series with LED for transmitted light launched by Leica Microsystems

Leica Microsystems has launched two instruments of the laser microdissection microscope series, the Leica LMD6 and the LMD7, with LED illumination for transmitted light. Users can now choose between halogen and LED illumination. LEDs are an energy-efficient light source providing homogenous illumination and a constant color temperature.

Activating bacterial receptors boosts macrophage response, limits damage to spinal cord following injury

Macrophages are cellular sentinels in the body, assigned to identify "attacks" from viruses, bacteria, or fungi and sound the alarm when they are present. However, these cells are a "double edged sword" in spinal cord injury, providing both neural repair-promoting properties and pathological functions that destroy neuronal tissue

Microbiota blocks the immune cells responsible for triggering allergies

The human body is inhabited by billions of symbiotic bacteria, carrying a diversity that is unique to each individual. The microbiota is involved in many mechanisms, including digestion, vitamin synthesis and host defense.

Researchers reveal how certain lipids help adenoviruses to enter the cell

Adenoviruses cause numerous diseases, such as eye or respiratory infections, and they are widely used in gene therapy. Researchers from the University of Zurich have now discovered how these viruses penetrate the cells, a key step for infection and gene delivery. The cell unwillingly supports virus entry and infection by providing lipids that are normally used to repair damaged membranes.

UTHealth scientist receives $1.9 million from NIH to develop non-antibiotic treatment for C. diff infections

Charles Darkoh, Ph.D., a researcher at The University of Texas Health Science Center at Houston School of Public Health, was recently awarded a five-year, $1.9 million R01 grant by the National Institutes of Health to develop a non-antibiotic treatment for Clostridium difficile (C. diff) infections.

Trial results show routine oral cholera vaccination programme protects people living in endemic regions

An oral cholera vaccine given as part of routine health services is safe and protects against severe cholera in children and adults in urban Bangladesh where the disease is endemic, according to the first real-life trial of this vaccine published in The Lancet.
