Healthcare a call away
Washington: University of California researchers have developed a lens-free imaging technique small enough to fit in a mobile phone, which can be a boon in developing countries where healthcare is non existent.
The study outlines improvements in a technique known as LUCAS, or ‘lensless ultra-wide-field cell monitoring array,’ platform based on shadow imaging.
LUCAS technique demonstrated a method for quickly and accurately counting targeted cell types in a homogenous cell solution. Removing lens from the imaging process allows LUCAS
University of California, Los Angeles researchers have further refined LUCAS technique to be able to classify a significantly larger sample volume – up to 5 ml, up from a tenth of one ml – representing a major step toward portable medical diagnostic applications.
The research team, led by Aydogan Ozcan, assistant professor of electrical engineering at the UCLA Henry Samueli School of Engineering and Applied Science, includes postdoctoral scholar Sungkyu Seo, doctoral student Ting-Wei Su, master’s student Derek Tseng and undergraduate Anthony Erlinger.
Ozcan envisions people one day being able to draw a blood sample into a chip the size of a quarter, which could then be inserted into a LUCAS-equipped cell phone that would quickly identify and count the cells within the sample. The read-out could be sent wirelessly to a hospital for further analysis.
These findings will be published in the quarterly Cellular and Molecular Bioengineering and is currently available online.

Mobile use leads to road accidents
Toronto: Canadian doctors have warned that using cell phone while driving adversely affects the brain’s capacity to identify the danger, its visual concentration, the speed to process information and hence its reaction time.
Basing their research on various studies from around the world, the Ontario Medical Association (OMA) doctors here say that there is a strong link between mobile use by drivers and road accidents around the world.
Their research points out that mobile use by drivers automatically led to a big reduction in their functional field of view, decreased safe distance between vehicles and slowed their brake reaction time. The use of mobile slowed the drivers’ response time to traffic light changes, 15 percent less response to traffic lights, and slowed braking by 18 percent.
Further, the use of mobile by the drivers reduced their visual monitoring of mirrors and instruments, with some abandoning them entirely. It also led to fewer glances at traffic lights and an increased tendency for hard braking.
“The evidence is clear that driving while using a mobile phone is dangerous to the driver, their passengers and others on or near the roadway,” said Ken Arnold, president of the OMA.
“Too many drivers treat talking on a phone while driving as a harmless practice.it’s not an easy prescription to give, but this practice has to be curtailed,” he said.
Arnold added, “`Doctors know all too well the consequences of driving while distracted and it is time that the right steps are taken to ensure the safety” of people.
Some states in America, Australia and many European countries have banned the use of cell phone while driving. In Canada, only four of the 10 provinces have put restrictions on the use of cell phones by drivers.
Since Ontario, which has more than 40 percent of the total Canadian population of 33 million, has no such laws to ban the practice, doctors have called for a legislation to discourage this habit.
