Epigenetic changes triggered by cigarette smoke may be earliest step in lung cancer development

Scientists at the Johns Hopkins Kimmel Cancer Center say they have preliminary evidence in laboratory-grown, human airway cells that a condensed form of cigarette smoke triggers so-called "epigenetic" changes in the cells consistent with the earliest steps toward lung cancer development.

Component of fire ant venom shows promise as a psoriasis treatment

In a new study involving laboratory mice, researchers have found that solenopsin and similar compounds could be beneficial for psoriasis.

Human cell-based methods could better identify asthma-causing chemicals, research suggests

Chemicals that could potentially cause asthma through an immune reaction could be better identified with human cell- and computer-based test methods, according to a new research paper co-authored by the Physicians Committee's Kristie Sullivan, M.P.H., in Applied In Vitro Toxicology.

Studies highlight risks associated with using e-cigarettes

Two new studies presented at the European Respiratory Society International Congress highlight the risks associated with using e-cigarettes, especially for those who also smoke conventional cigarettes.

Nurses at risk of chronic lung disease COPD due to regular disinfectant use

According to a new study, nurses who are work disinfectants continually through their careers are more likely to develop a chronic lung disease called chronic obstructive pulmonary disease (COPD).

CWRU professor wins $3.9 million NIH grant to identify countermeasures against chemical hazards

Kurt Lu, MD, assistant professor of dermatology at Case Western Reserve University School of Medicine, has received a five year, $3.9 million grant from the National Institutes of Health to expand countermeasures against chemical threats, including mustard gas and mustard-related compounds.

Study provides first structural glimpse of circadian clock's molecular machinery

Scientists have long known that circadian clocks- biochemical oscillators that control physiology, metabolism and behavior on a roughly 24-hour cycle- are present in all forms of life, including animals, plants, fungi and some types of bacteria. However, the molecular mechanisms that "run" these systems remain largely unknown.

Early signs of cardiovascular risk found in children exposed to 9/11 dust

Sixteen years after the collapse of the World Trade Center towers sent a "cloud" of toxic debris across Lower Manhattan, children living nearby who likely breathed in the ash and fumes are showing early signs of risk for future heart disease.

New device detects cancerous tissue during surgery within seconds

Researchers from the University of Texas at Austin have invented a pen-like, handheld device that can identify cancerous tissue in around 10 seconds during surgery, offering hope that procedures to remove cancer could be made quicker, more precise and safer.

Four year $1.4 million Air Force grant supports WVU biologists to explore moths’ olfactory systems

As humans walk and talk, we sense our own movements or sounds. Yet, we can distinguish our actions from everything else in our environment that affects our senses.

Newly-discovered mutation highlights complex genetic network that underpins blood disorder

Porphyrias, a group of eight known blood disorders, affect the body's molecular machinery for making heme, which is a component of the oxygen-transporting protein, hemoglobin. When heme binds with iron, it gives blood its hallmark red color.

Biodegradable nanoparticle injected after spinal cord injury limits damage

After a spinal cord injury, a significant amount of secondary nerve damage is caused by inflammation and internal scarring that inhibits the ability of the nervous system to repair itself.

Higher intake of red meat, poultry linked to greater diabetes risk

While a plant-based diet is generally considered healthier than a meat-based diet in preventing the risk of diabetes, not all meats affect the risk equally.

Mayo Clinic experts move closer to realizing clinical potential of senolytic drugs on aging

Researchers are moving closer to realizing the clinical potential of drugs that have previously been shown to support healthy aging in animals.

Inflammation originating from abdominal fat precedes development of sleep apnea, findings suggest

Inflammation is traditionally thought of as a symptom of sleep apnea, but it might actually precede the disorder, potentially opening the door for new ways to treat and predict sleep apnea, according to researchers.

Researchers identify cytotoxic nature of two-dimensional black phosphorous

When environmental and soil chemist Baoshan Xing at the University of Massachusetts Amherst began reading in 2014 that a new, two-dimensional material known as layered black phosphorous (BP) was gaining the attention of biomedical researchers for use in drug delivery systems and tumor photothermal therapy, he was both intrigued and concerned.

Olfactory tissue regeneration requires inflammatory processes that create loss of smell

In a mouse study designed to understand how chronic inflammation in sinusitis damages the sense of smell, scientists at Johns Hopkins say they were surprised to learn that the regeneration of olfactory tissue requires some of the same inflammatory processes and chemicals that create injury and loss of smell in the first place.

Study sheds new light on gene fusion in bladder and brain cancer

A study by the University of Warwick sheds new light on gene fusion in bladder and brain cancer.

Researchers find increase in adverse birth outcomes due to high levels of pesticide exposure

Although common opinion holds that exposure to pesticides increases adverse birth outcomes, the existing body of scientific evidence is ambiguous. Logistical and ethical barriers -- pesticide use data are not widely available and randomized control trials are impossible -- have gotten in the way of more accurate conclusions.
