BRUSSELS， Feb. 15 (Xinhua) -- The European Commission on Wednesday warned Germany， France， Spain， Italy and Britain for continually breaching air pollution limits for nitrogen dioxide (NO2) and urged them to take action to address the problem.
European Union (EU) legislation on ambient air quality sets limit values for air pollutants， including NO2. Member states are required to adopt and implement air quality plans that set out appropriate measures to ensure good air quality.
If a member state fails to act within two months， the Commission may decide to take the matter to the Court of Justice of the EU.
According to a statement of the Commission， legal action on NO2 involves 12 member states such as Austria， Belgium， the Czech Republic， to name a few.
More than 400，000 citizens die prematurely in the EU each year as a result of poor air quality， it said， and millions more suffer from respiratory and cardiovascular diseases caused by air pollution.
High levels of NO2 caused almost 70，000 premature deaths in Europe in 2013， said the statement. Road traffic is responsible for around 40 percent of nitrogen oxides emissions in the EU， according to official data.
Of the total emitted nitrogen oxides from traffic， around 80 percent comes from diesel powered vehicles.
VANCOUVER Nike Air Max 98 Günstig , Aug. 29 (Xinhua) -- An herb widely used in traditional Chinese medicine might hold the key to a new osteoporosis therapy that could prevent bone loss without causing side effects, said a new study.
The Journal of Bone and Mineral Research published by Canada's University of British Colombia (UBC) reported the new findings Tuesday.
Using a compound derived from red sage, UBC researchers have found a way to selectively block an enzyme called Cathepsin K (CatK), which plays a major role in the breakdown of collagen in bones during osteoporosis.
The development of osteoporosis drugs by pharmaceutical companies has focused heavily on blocking CatK in recent years.
Quite a number of clinical trials to date have failed due to side effects ranging from stroke Nike Air Max 97 Günstig , skin fibrosis and cardiovascular issues.
The researchers tested a compound derived from red sage in human and mouse bone cells and a mouse model.
They found that it prevented bone loss and increased the bone mineral density of the mice treated with the compound by 35 percent, when compared with the control group.
The research builds on a previous research which focused on the effectiveness of red sage, known as Danshen in Chinese and used to treat bone ailments, in stopping the activity of CatK in limited ways.
Enzyme blockers work like keys in locks. Most drugs in development have been so called active site-directed inhibitors Nike Air Max 96 Günstig , which act like master keys and lock the entire enzyme, blocking both its disease-relevant functions such as collagen degradation and its other normal functions.
CatK is a multifunctional enzyme with important roles in other parts of the body, completely blocking it is what causes unexpected side effects in other drugs.
The UBC red sage compound only locks the collagen-degrading CatK activity, preventing the unregulated breakdown of collagen in bones without any other negative impacts.
The treatment could also potentially be used to treat a variety of other bone and cartilage diseases such as arthritis and certain bone cancers.
Osteoporosis is a global health problem that will affect one out of three women and one out of five men worldwide Nike Air Max 95 Damen Günstig , with a multi-billion-dollar pharmaceutical industry dedicated to finding treatments to stop its progression.

BEIJING, Sept. 27 (Xinhua) -- Chinese President Xi Jinping's speech delivered Tuesday at the opening ceremony of the 86th Interpol General Assembly has been applauded by many overseas scholars and officials.
Speaking at the general assembly in Beijing Nike Air Max 95 Grün Günstig , Xi said China hopes to work closely with countries and international organizations on global security, and jointly build universal security for humankind.
In order to beef up global law enforcement and security cooperation, Xi proposed the need to enhance reform and innovation, uphold the rule of law and seek mutual benefits. The Chinese president also vowed stronger support for Interpol in the next five years to raise its global influence and leadership.
Xi's speech at the Interpol meeting showed that China Nike Air Max 95 Rosa Günstig , faced with new challenges in the 21st century, is ready to be a cooperation partner and play a decisive role, said Fernando Reyes Matta, former Chilean ambassador to China.
Xi's speech had two major messages. The first one is that China aspires to forge close cooperation with other nations so that it could be more efficient in dealing with security issues Nike Air Max 95 Schwarz Günstig , said Reyes, who is now director of the Latin American Center for Chinese Studies at Andre Bello University.
The second is that China hopes to share its experience and knowledge on security with other countries to help them improve national security and stability, he said.
Reyes added that Xi's pledge to support Interpol is a sign of how China views its role in an emerging new world order.
