Exercise alters brain's dopamine system to help treat addiction, study finds

New research by the University at Buffalo Research Institute on Addictions has identified a key mechanism in how aerobic exercise can help impact the brain in ways that may support treatment - and even prevention strategies - for addiction.

Lung-on-a-chip technology could streamline drug-testing for pulmonary fibrosis

Developing new medicines to treat pulmonary fibrosis, one of the most common and serious forms of lung disease, is not easy.

Cancer cells co-opt pain-sensing 'neural channel' to increase tolerance against oxidative stress

Anyone who's taken a bite of a sandwich with too much spicy mustard or a piece of sushi with too much wasabi can attest to the tear-inducing sensation these condiments can cause. These loud warnings to the nervous system of exposure to potentially harmful chemicals are triggered by TRPA1, a calcium channel protein sometimes referred to as the "wasabi receptor."

AACN outlines evidence-based protocols and clinical strategies to manage alarms

Clinical alarms are designed to alert clinicians to changes in their patients' conditions, but their sheer numbers and resulting noise instead pose a significant threat to patient safety, according to the American Association of Critical-Care Nurses.

Scientists uncover the cause of insulin resistance in obesity

A team of international researchers has identified a pathway by which obesity results in reduced insulin sensitivity.

Researchers take important step toward finding protein biomarkers during cancer surgery

Isabelle Fournier and her team are out to change surgical oncology. "Better surgery is associated with better prognosis and higher survival," said Fournier, a professor at the University of Lille and co-director of a proteomics center of INSERM, the French national institute of health.

Investigational technology could increase donor organ supply for lung transplants

As many as 80 percent of lungs from organ donors are not used, either because they are not in good enough condition to transplant, or there are doubts about their quality and there is no way to verify their condition.

New way of grouping atoms could herald novel materials, drugs and computers

Scientists have found a new way of joining groups of atoms together into shape-changing molecules - opening up the possibility of a new area of chemistry and the development of countless new drugs, microelectronics and materials with novel characteristics.

Researchers uncover clues to early lung transplant failure

Among organ transplant patients, those receiving new lungs face a higher rate of organ failure and death compared with people undergoing heart, kidney and liver transplants. One of the culprits is inflammation that damages the newly transplanted lung.

New LIVE scoring tool effectively predicts future risk of hospitalization for COPD patients

Researchers have developed a new tool that utilizes basic laboratory tests to effectively identify patients with chronic obstructive pulmonary disease who are at high risk of being hospitalized due to a flare up of the condition.

Intermittent fasting may increase diabetes risk, shows study

Fasting every other day to lose weight impairs the action of sugar-regulating hormone, insulin, which may increase diabetes risk, according to data presented in Barcelona at the European Society of Endocrinology annual meeting, ECE 2018.

Updated SSC Bundle aims to improve survival for sepsis patients

For patients with sepsis, a serious infection causing widespread inflammation, immediate treatment is essential to improve the chances of survival. An updated "Hour-1 Bundle" of the international, evidence-based guidelines for treatment of sepsis is introduced in the June issue of Critical Care Medicine.

L.A. County unlawfully terminated thousands of Medi-Cal recipients, court rules

Los Angeles County unlawfully dropped an estimated 22,000 people from California's Medicaid program, including low-income seniors and disabled residents who couldn't get vital medications and medical care after their coverage was terminated, according to a court ruling late last week.

Automated system more accurate in identifying patients at risk for ventilator-associated pneumonia

An automated system for identifying patients at risk for complications associated with the use of mechanical ventilators provided significantly more accurate results than did traditional surveillance methods, which rely on manual recording and interpretation of individual patient data.

Cardiac arrest patients using newer laryngeal breathing tube may have higher survival rate, study shows

In a landmark study, researchers found that patients treated with paramedic oxygen delivery using a newer, more flexible laryngeal breathing tube may have a greater survival rate after sudden cardiac arrest than the traditional intubation breathing tube.

Increasing physical activity over six years associated with decreased heart failure risk

By analyzing reported physical activity levels over time in more than 11,000 American adults, Johns Hopkins Medicine researchers conclude that increasing physical activity to recommended levels over as few as six years in middle age is associated with a significantly decreased risk of heart failure, a condition that affects an estimated 5 million to 6 million Americans.

Biochemists isolate protein supercomplex from bacteria that generates voltage

Biochemists at the University of Illinois have isolated a protein supercomplex from a bacterial membrane that, like a battery, generates a voltage across the bacterial membrane.

Researchers use spheroids to screen for potential cancer drugs

Researchers from The Scripps Research Institute have reported a new and more effective way of screening for potential cancer drugs.

Adding chemotherapy to treatment regimen can give children with PVS a chance to grow up

Pulmonary vein stenosis (PVS) is a rare disease in which abnormal cells build up inside the veins responsible for carrying oxygen-rich blood from the lungs to the heart. It restricts blood flow through these vessels, eventually sealing them off entirely if left untreated.

New therapeutic strategy exploits acquired vulnerability in drug-resistant cancer

Cancer cells that develop resistance to drugs, pay a price for this, by simultaneously developing a new vulnerability. If this acquired vulnerability can be identified, it may be exploited clinically.
