Deposition pattern of aerosolized Legionella using an ex vivo human-porcine respiratory model

By |2017-11-23T01:33:51+00:00November 23rd, 2017|

Abstract Legionella are bacteria responsible for severe lung pathologies. However how they enter and are deposited within the respiratory tract remains poorly documented. Data using animal testing led to the establishment of mathematical models allowing the estimation of aerosol dispersion risks. But direct extrapolation to humans is questionable and experimental models more physiologically representative of the [...]

Surge in human H7N9 cases caused by poultry, not people

By |2017-11-23T01:26:11+00:00November 23rd, 2017|

“Reassuring” study findings indicate that the recent surge in human influenza A(H7N9) cases in China is probably due to increased spread from poultry to people and not because of a swell in human-to-human transmission. With a case fatality rate of around 40%, experts consider H7N9 to be one of the most troubling infectious disease threats in the [...]

NANOSPONGES SHOW PROMISE FOR POTENTIALLY BLINDING EYE INFECTIONS

By |2017-11-23T01:17:35+00:00November 23rd, 2017|

Washington, DC – November 22, 2017 – In recent years, the number of eye surgeries for conditions including cataracts and glaucoma has dramatically increased and with it, so has the number of potentially blinding intraocular infections. In a new study, researchers demonstrate using a mouse model that engineered nanosponges can be used to protect eyes from [...]

Getting Personal: The Future of Flu Vaccines

By |2017-11-23T01:14:52+00:00November 23rd, 2017|

Does a 250-pound male linebacker need the same flu vaccine as a 120-pound female dancer? Probably not. Biomedical research has established that factors such as gender, age and body composition can affect the body’s immune responses prompted by vaccination. Pregnancy, a weakened immune system, and allergies to substances like egg or yeast proteins in vaccines [...]

Kill switches for engineered microbes gone rogue

By |2017-11-23T01:11:35+00:00November 23rd, 2017|

Stable autonomous kill switches ensure biocontainment of living microbes designed as devices for medicine or the environment (BOSTON) — Synthetic biologists are fitting the genomes of microorganisms with synthetic gene circuits to break down polluting plastics, non-invasively diagnose and treat infections in the human gut, and generate chemicals and nutrition on long haul space flights.

North Texas flu spike

By |2017-11-23T01:08:30+00:00November 23rd, 2017|

Health officials in North Texas are warning about a spike in flu cases in adults and children ahead of the Thanksgiving holiday. According to Medical City Arlington officials, flu is up in Southeast Tarrant County. Medical City Arlington and Medical City Arlington ER Grand Prairie reports almost 200 cases last week. "We've seen a large amount of [...]

Not Just Antibiotics: Is Cancer Chemotherapy Driving Antimicrobial Resistance?

By |2017-11-23T01:03:57+00:00November 23rd, 2017|

The global spread of antibiotic-resistant pathogens threatens to increase the mortality of cancer patients significantly. We propose that chemotherapy contributes to the emergence of antibiotic-resistant bacteria within the gut and, in combination with antibiotics, drives pathogen overgrowth and translocation into the bloodstream. In our model, these processes are mediated by the effects of chemotherapy on [...]

Why cooking a stir fry could be bad for health, according to scientists

By |2017-11-23T00:07:58+00:00November 23rd, 2017|

It may seem like a healthy option, but cooking a stir-fry could be bad for health because it shoots microscopic particles of fat into the air, which may be hazardous if inhaled, scientists have warned. Researchers at Texas Tech University and Utah State University heated up oil in a frying pan and then recorded what happened when [...]
