Inhibiting Stress Oxidant May be New Therapy for COPD

21.04.2008
A study in Clinical and Experimental Pharmacology and Physiology published by Wiley-Blackwell has showed that the generation of oxidative stress increases pulmonary inflammation – thus encouraging the development of airway obstruction associated with chronic obstructive pulmonary disease (COPD).

The study “Oxidative Stress is an Important Component of Airway Inflammation in Mice Exposed to Cigarette Smoke or Lipopolysaccharide” investigates the inflammatory responses in oxidative stress-deficient mice exposed to cigarette smoke. The authors employ a cigarette smoke model to understand the role of oxidative stress in the pathogenesis of COPD, and suggested that further investigations of the efficacy of new compounds that may help treat respiratory disorders.

Cigarette smoking is the main cause of respiratory disorders such as chronic bronchitis, emphysema and COPD. Smokers and patients with COPD generally display an increased oxidative stress level as compared to healthy patients.

Lead author Vincent Lagente, Professor of Pharmacology at the University of Rennes 1 in France says, “Overwhelming evidence shows that- compared to non-smokers and healthy patients – smokers and patients with COPD display an increased level of oxidative stress, and suffer from an imbalance in oxidants in airway inflammation. As classic anti-inflammatory compounds are ineffective in treating respiratory disorders, and the effects of cigarette smoke on COPD are still not completely understood, we have developed a cigarette exposure protocol that results in airway inflammation to better understand the physiopathology of the inflammatory process.”

In examining the response of mice exposed to cigarette smoke, researchers found that those with reduced oxidative stress showed lesser inflammatory symptoms – hence suggesting the association of oxidative stress with COPD and supporting the development of anti-oxidant therapy for smoking related-diseases.

Im Focus: Significantly more productivity in USP lasers

In recent years, lasers with ultrashort pulses (USP) down to the femtosecond range have become established on an industrial scale. They could advance some applications with the much-lauded “cold ablation” – if that meant they would then achieve more throughput. A new generation of process engineering that will address this issue in particular will be discussed at the “4th UKP Workshop – Ultrafast Laser Technology” in April 2017.

Even back in the 1990s, scientists were comparing materials processing with nanosecond, picosecond and femtosesecond pulses. The result was surprising:...

Im Focus: Novel silicon etching technique crafts 3-D gradient refractive index micro-optics

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.

Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...

Im Focus: Quantum Particles Form Droplets

In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.

“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...

Im Focus: MADMAX: Max Planck Institute for Physics takes up axion research

The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.

The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...
