BPA activates immune response in mice that passes down through generations
15 Jan 2020 at 9:06am
Some plastic food and beverage containers still contain bisphenol A (BPA), which can mimic the hormone estrogen. Although experts say that small amounts of BPA detected in foods are unlikely to cause problems, some people worry that constant low-level exposures could have health effects, especially for developing fetuses, infants and children. Now, researchers report that in mice, BPA activates an immune response that persists for at least three generations.
Genetic anomaly associated with poor response to common asthma treatment
13 Jan 2020 at 12:33pm
A new study has uncovered a genetic anomaly associated with poor response to a common asthma treatment. The findings showed that asthmatic patients with the gene variant are less likely to respond to glucocorticoids and often develop severe asthma.
Meta-analysis indicates that one-fifth of the world's population exposed to T...

Human toxocariasis -- a neglected tropical disease found worldwide, can cause a range of allergic, neurological, cardiac, and other symptoms. However, it also goes unnoticed in many people who contract the infection. Now, researchers report that about 19% of the world's human population carries antibodies against Toxocara.
Asthma severity linked to microbiome of upper airway
16 Dec 2019 at 8:01am
A new study suggests there is a link between bacteria that live in the upper airway and the severity of asthma symptoms among children with mild to moderate asthma.
Study highlights high cost of fossil fuel pollution on children's health
12 Dec 2019 at 1:33pm
A new study has compiled the estimated per-case costs of 6 childhood health conditions linked to air pollution -- estimates that can be incorporated into benefits assessments of air pollution regulations and climate change mitigation policies.
Dramatic health benefits following air pollution reduction
6 Dec 2019 at 2:36pm
Reductions in air pollution yielded fast and dramatic impacts on health-outcomes, as well as decreases in all-cause morbidity, according to new findings.
Migraine headaches? Consider aspirin for treatment and prevention
3 Dec 2019 at 6:10am
Evidence from 13 randomized trials of the treatment of migraine in 4,222 patients and tens of thousands of patients in prevention of recurrent attacks supports the use of high dose aspirin from 900 to 1,300 milligrams to treat acute migraine as well as low dose daily aspirin from 81 to 325 milligrams to prevent recurrent attacks. Aspirin is available without a prescription, is inexpensive, and has a relatively favorable side-effect profile compared to alternative more expensive medications.
Evidence in mice that childhood asthma is influenced by the neurotransmitter ...
19 Nov 2019 at 10:25am
Neurons that produce the neurotransmitter dopamine communicate with T cells to enhance allergic inflammation in the lungs of young mice but not older mice, researchers report. The findings potentially explain why asthma susceptibility is higher in children. By highlighting the important role of interactions between the nervous system and the immune system in childhood asthma, the results could lead to new strategies for treating the common chronic disease.
Allergy shots may be an effective treatment for pediatric pollen food allergy...

A new study shows allergy shots (subcutaneous immunotherapy) can be effective in reducing PFAS symptoms for pediatric patients.
Developing new delivery tools for gene editing
31 Oct 2019 at 2:46pm
Scientists are using simple peptides to deliver gene-editing tools into notoriously hard-to-access lung and airway cells with the goal of creating new treatments for people with diseases like cystic fibrosis, COPD, and asthma.
How Chlamydia gain access to human cells
30 Oct 2019 at 10:27am
Infection biologists have found out how the LIPP protein helps Chlamydia to infect human cells. These insights could provide the basis for prevention of chlamydial infections.
Prenatal air pollution exposure linked to infants' decreased heart rate respo...
30 Oct 2019 at 4:33am
A mother's exposure to particulate air pollution during pregnancy is associated with reduced cardiac response to stress in six-month-old infants, according to new research. This study is among the first to find that particulate air pollution exposure in utero can affect heart rate variability, which is a known risk factor for health issues.
Crimped or straight? Lung fiber shape influences elasticity
28 Oct 2019 at 2:51pm
Stiff collagen and stretchy elastin fibers packed together in rows allow the respiratory system to stretch and snap back into shape. Scientists previously thought these fibers govern the mechanics of the airways due to their composition. New research has instead observed that differences in the shape and form of tissue fibers influence respiratory elasticity. These findings will help scientists better understand lung diseases, from chronic diseases like COPD to the lung ailment associated with vaping.
Research tests speed of drones in responding to medical emergency scenarios
25 Oct 2019 at 4:59am
Could drones be used someday to deliver life-saving medications or interventions in the case of a child's emergency, a drug overdose or in response to a mass casualty scene? According to new research, it's an idea worth exploring.
A higher resolution image of human lung development
18 Oct 2019 at 7:05am
Researchers provide clearer picture of how lungs develop and discover novel markers to differentiate populations of lung cells implicated in lung diseases of premature babies.
