Cancer cells co-opt pain-sensing 'wasabi receptor' to survive oxidative stress
24 May 2018 at 11:16am
Some cancers express unusually high levels of a neural calcium channel known as the 'wasabi receptor,' which plays a role in detecting pain, cold and other sensations. New research finds cancer cells co-opt this neural channel to increase their tolerance against toxic oxidative stress. Blocking the activity of this channel in mice curbs tumor growth and makes cancer cells more sensitive to chemotherapy.

A new article shows allergies can have serious, far-reaching consequences, especially on adolescent sufferers.
Source of molecule linked to nasal polyps, asthma attacks
23 May 2018 at 10:12am
A new discovery about how the immune system responds to common sinus infections and asthma could explain why patients develop these issues in the first place and ultimately may lead to improved targeted therapies.
New treatment for severe asthma
22 May 2018 at 2:00pm
Researchers have developed a new method to treat severe asthma. In a study of over 200 participants with severe asthma, the new treatment was shown to have improved asthma symptoms and lung function, while reducing the need for corticosteroids by up to 70%.

21 May 2018 at 3:47pm
Women who are unable to quit smoking during their pregnancy may reduce the harm smoking does to their baby's lungs by taking vitamin C, according to a new randomized, controlled trial.
Eczema drug effective against severe asthma
21 May 2018 at 11:39am
New studies of patients with difficult-to-control asthma show that the eczema drug dupilumab alleviates asthma symptoms and improves patients' ability to breathe better than standard therapies. Dupilumab, an injectable anti-inflammatory drug, was approved in 2017 by the Food and Drug Administration as a treatment for eczema, a chronic skin disease.
Alternative treatment for mild asthma
16 May 2018 at 2:23pm
People with mild asthma are often prescribed a daily treatment regimen, but up to 80 per cent do not follow the routine, using inhalers only when they have an asthma attack. Now the researchers have found an as-needed combined-drug inhaler is a viable treatment option.
How electronic health records can benefit clinical trials
16 May 2018 at 7:14am
A new study has indicated that the Secure Anonymized Information Linkage (SAIL) Databank can provide a simple, cost-effective way to follow-up after the completion of randomized controlled trials.
Keeping kids with asthma out of the hospital

Only multimodal interventions that combined multiple categories were effective at reducing the risk of readmission for pediatric asthma between 30 days and one year after initial discharge, Children's research finds.
A high-fiber diet protects mice against the flu virus
15 May 2018 at 8:38am
Dietary fiber increases survival in influenza-infected mice by setting the immune system at a healthy level of responsiveness, according to a preclinical study published May 15 in the journal Immunity. A high-fiber diet blunts harmful, excessive immune responses in the lungs while boosting antiviral immunity by activating T cells. These dual benefits were mediated by changes in the composition of gut bacteria.
Occupational exposures linked with increased risk of COPD
9 May 2018 at 7:49am
A study with more than 3,300 participants in 12 countries has established a relationship between occupational exposure to biological dusts, gases, fumes and pesticides and COPD. The researchers did a follow-up of the participants 20 years after the first assessment.
Nutmeg's hidden power: Helping the liver
9 May 2018 at 7:49am
Smelling nutmeg evokes images of fall, pumpkin pie and hot apple cider. But the spice has been used for years in traditional Chinese medicine to treat gastrointestinal illnesses. Now one group reports that they have figured out how nutmeg helps other organs, specifically the liver.
Correlation between secondhand marijuana and tobacco smoke exposure and child...
5 May 2018 at 6:18am
Marijuana is the most commonly used illicit substance in the US. Secondhand marijuana smoke (SHMS) exposure and its subsequent impact on child health have not been studied. The objective of this study was to determine association between SHMS exposure and rates of emergency department visitation, and rates of tobacco sensitive conditions (asthma, otitis media and viral respiratory infections).
Study points to the futility of urine tests for salbutamol doping
3 May 2018 at 11:27am
Salbutamol, also known as albuterol, is a medication that opens up constricted medium and large airways in the lungs and is often used to treat asthma.
New test safely and accurately diagnoses peanut allergies
3 May 2018 at 5:56am
Scientists have developed a new laboratory test to diagnose peanut allergy. The test has 98 percent specificity and, unlike current options, it doesn't run the risk of false-positives or causing allergic reactions such as anaphylactic shock.
