Space research leads to needle-free blood tests

...ow much oxygen there is in the blood, by placing a sensor on the finger or ear. It's a standard piece of equipment in the intensive care unit. But we could do far more with near infrared. The researchers are currently looking at how to take account of different skin colours and levels of body fat in interpr...

Massage therapy regulates sleep cycle of newborns

... the infants were not massaged. Researchers used a sensor to measure the infants' daytime and nighttime activity before and after the treatment. Quantities of a byproduct of Melatonin, a sleep-regulating hormone secreted by the pineal gland at night was measured in the babies at 6,8 and 12 weeks of age. Th...

Accuracy Of Lung Function Test Questioned

...correctly. Another common error can occur when the sensor is obstructed by condensation of water vapor, mucus, or the subject’s fingers. Researchers say these two problems are especially dangerous because the high values they produce replace accurate but lower values recorded during testing, leading the te...

An insight of the small intestine

...ght hours, pictures are taken and transmitted to a sensor worn on the person's abdomen.// The pictures can then be viewed to show lesions in areas that are not accessible by a colonoscopy or endoscopy. This technology, while allowing for a great deal more diagnostic ability, has some downsides, according t...

... which two wires intersect in each matrix provides sensor readings, with changes in current indicating fluct...orm the finished e-skin. The distance between each sensor in the matrices is roughly four centimetres and sensitivity to temperature and pressure has yet to b...

A Novel Method For Measuring Interstitial Fluid Pressure In Cancer Tissues

...passed through the lumen of a surgical needle. The sensor is kept in the lumen of the needle during penetration into the tumor. The sensor tip is then introduced into the center core of the tumor as the needle sleeve is withdrawn from the ...

New sensors developed to predict effectiveness of radiotherapy treatment

...recise dose of radiation is being delivered. New sensor systems have now been developed that can assess th...sful, there would soon be commercialization of the sensor system. This is hoped to reduce the side effects patients associated with radiotherapy by improving ...

Bacterial Photographs Created By Student Scientists!

...eptor protein (derived from blue-green algae) to a sensor normally present on the bacterial cell surface for determination of salt concentration. This light receptor system was then designed to communicate with a pigment control system. Once light was sensed by the receptor, it inactivated certain genes a...

New Sensor Created For Lung Disorder Patients

New Gadget To Protect The Eyesight Of Children

... top of a TV set. It uses a passive infrared (PIR) sensor to judge the distance between the TV set and the viewer. "Parents can pre-set the allowed distance between the TV and the viewer. When the child sits too close, the TV Magic Tool shouts 'My friend, you are sitting too close!' If the child does not...

New Implantable Cardioverter Defibrillators to avoid unnecessary shocks

...leading to unpleasant situation. This new ICDs has sensor electrodes and magnets, which make them accurately receive electrical activity against which electric current can be given. This new device has the advantage of detecting shocks accurately, which avoids unnecessary electric treatment. Researchers fee...

Sensor Can Detect "Unhealthy" Molecules In Breath

...r Paul Thomas led a team of researchers in using a sensor employed to check out explosives at the airports. // The sensor, called a microDMxTM sensor was developed by Sionex Corporation, is now being used by researchers to detect "unhealthy" molecule...

Biosensor Chips to detect Urinary Tract Infections

...ochemical signals causing an elevated level in the sensor which is estimated accurately and this research work is funded with $ 5.6 million by the National Institute of Biomedical Imaging and Bioengineering....

New Sensor To Monitor Oxygen Deprivation In Babies During Birth

...metabolizing hypoxanthine is incorporated into the sensor as well. Human clinical trials of the biochemical ...td, regarding further direction of the biochemical sensor project. If promising results are obtained, then doctors could soon have a medical device that can...

New Multi-functional Sensing Tool To Investigate Cystic Fibrosis

...AFM-SECM approach. “There are a lot of emerging sensor technologies, but few have been adapted for routine use in medical research, which is one of the development goals at the Applied Sensors Lab,” Mizaikoff said. “As analytical chemists, we want to develop quantitative sensing devices that can answer i...

3-D Imaging For Monitoring Reactor Systems, Power Plants

... Anniversary Symposium. The invention includes a sensor system that measures the capacitance of the materials inside the reactor -- their ability to store an electrical charge. Software then converts those measurements to information about the materials' composition. Materials flow inside these hot reac...

Polymer Molecule Layered On Carb Molecule to Increase Sensitivity

...Lin said, it should be possible to build a similar sensor using other enzymes that react specifically with other biological chemicals, environmental agents or even microbes and their toxic byproducts. Lin and colleagues also reported, in February issue of Analytical Chemistry, having used a similar techniqu...

Orissa Boy Invents Unique Communication Device For Paralysed

...ate the device,' he said, adding the data from the sensor was processed and forwarded to the data transmission section. 'Subsequently, the receiver forwards the data to the micro-controller which is used to select and surf the menu. Finally, it reaches the pre-recorded message that helps a disabled person...

Growth Factors Help Neurons to Reach Their Correct Destination

...ach their destination in mouse mutants lacking the sensor molecule. Finally, using mice engineered to express a fluorescent protein in MMCm neurons, the investigators demonstrated that only the glowing neurons extended axons in the direction of target cells expressing FGF. ‘After a lot of hard work, we narr...
