Washington: Scientists have developed a new test that can easily measure common stress hormones using sweat, blood, urine or saliva. Stress is often called “the silent killer” because of its stealthy and mysterious effects on everything from heart disease to mental health. Researchers from the University of Cincinnati in the US hope to turn the system into a simple device that patients can use at home to monitor their health. “I wanted something that’s simple and easy to interpret. This may not give you all the information, but it tells you whether you need a professional who can take over,” said Andrew Steckl, a professor at University of Cincinnati.

These stress biomarkers are found in all of these fluids, albeit in different quantities, Steckl said. “It measures not just one biomarker but multiple biomarkers. And it can be applied to different bodily fluids. That’s what’s unique,” he said. The device, described in the journal American Chemical Society Sensors, is not intended to replace full-panel laboratory blood tests.

And it sneaks up on you. You don’t know how devastating a short or long duration of stress can be,” said Prajokta Ray, from University of Cincinnati. “So many physical ailments such as diabetes, high blood pressure and neurological or psychological disorders are attributed to stress the patient has gone through. That’s what interested me,” said Ray. Taking exams always gave her stress. Understanding how stress affects you individually could be extremely valuable, she said. “Stress has been a hot topic over the past couple years. Researchers have tried very hard to develop a test that is cheap and easy and effective and detect these hormones in low concentrations,” Ray said. “This test has the potential to make a strong commercial device. It would be great to see the research go in that direction,” she added.
New Delhi: A 55-year-old woman reportedly jumped to her death from the fourth floor of a building here, police said. The victim was identified as Sunita. The incident took place in Dwarka’s Bharat Vihar area. “It may look like a case of suicide but a clear answer will be available only after the post-mortem report. We are looking for other possibilities,” a senior police official said.
21 February 2012A five-member group of experts from the United Nations atomic energy watchdog is today continuing its visit to Iran, where the members are holding talks with officials about international concerns over the country’s nuclear programme. The talks in Tehran are “aimed at resolving all outstanding issues in relation to Iran’s nuclear programme,” the International Atomic Energy Agency (IAEA) reported today in a press release.“We hope to have a couple [of] good and constructive days in Tehran,” said Herman Nackaerts, the deputy director general for safeguards at IAEA and the head of the mission, before the team left Vienna – where the agency is headquartered – late on Sunday.“This is, of course, a complex issue that may take a while, but we hope it will be constructive,” he said, adding that the agency hopes “to have some concrete results after this trip.”IAEA experts also visited Tehran last month to discuss issues of concern, which focus on the clarification of possible military dimensions to Iran’s nuclear programme.Iran has repeatedly stated that its nuclear programme is for the peaceful purpose of providing energy, but some countries contend it is seeking to develop nuclear weapons.The Security Council has imposed four rounds of sanctions against Iran, citing the proliferation risks of its nuclear programme and its continued failure to cooperate with the IAEA.
