Siemens has introduced its new mobile X-ray system a “digital X-ray room on wheels”. Mobilett XP CR, the mobile X-ray workstation, helps in bedside imaging. The incorporated monitor can deliver results of the examination in less than 50 seconds for first image review in the hospital room. And images can be achieved directly at the patient’s bedside. Also, there is additional time saving as compared to stationary X-ray systems, since basic image processing steps such as changes in brightness and contrast as well as edge enhancement can be performed directly at the mobile system and no separate devices are required. By using different-sized image cassettes, the physician is able to quickly display different anatomical regions. This means that the system masters demanding imaging tasks, for example, in surgery wards or neonatal departments. In emergency cases, the Mobilett XP CR can be used as the central CR reader for a ward. The Mobilett XP CR shows high ease of use. It is easy to handle, compact and easy to maneuver. The patient can be recumbent, sitting or in any other position. It is also possible to control the Mobilett XP CR via remote from a maximum distance of approximately 30 feet.
Patients suffering from disease or injury that leave them unable to move have little hope of independent mobility. However there is good news for them. Researchers are developing a thought-controlled robotic wheelchair. Spanish scientists have begun work on a new brain-computer interface, or BCI, capable of converting thought into commands that a wheelchair can execute. Javier Minguez, a researcher at the University of Zaragoza “We are planning to use non-invasive devices to record the rhythms from the surface of the skull, we also plan to use this system with a school for disabled children.” Dawn Taylor, an assistant professor says “You’re not going to be using EEGs to control a robotic arm to play the piano or anything but you can certainly turn right and left and stop and go using that sort of signal. Two 800-MHz Intel computers mounted on the wheelchair will process these readings and send instructions to the wheels. A front-mounted laser will work as a sensor, detecting obstacles ahead and changes in the environment, like furniture that has been moved. This is particularly important for people with limited head and neck mobility, as they often cannot clearly see the way ahead, especially at ground level.
Overweight children may not only have health hazards, but can also have higher risk of foot problem. Kids who carry surplus pounds may be doing unending damage to their feet. Dr. Darryl Haycock a foot and ankle surgeon in private practice in Lima, Ohio says “When there is an increased amount of weight and stress being placed on the foot, it can cause some significant changes in foot structure. Children’s feet aren’t fully developed until the age of 14 or 15 for girls, 15 to 17 for boys, meaning their foot bones are “easily moldable.” As few as 15 to 20 extra pounds can add to flattening of the arches and inflammation of the growth plate in the heel. It’s difficult to determine whether children are obese because they have foot problems in the first place, which make it painful for them to be active, or whether the obesity is causing the changes in foot structure. Children and adolescents who are overweight are more likely than their normal weight counterparts to suffer bone fractures and have joint and muscle pains, according to a study conducted at the National Institutes of Health.
Australian researchers found out that -Left-handed people can think more quickly in carrying out various tasks such as playing computer games or playing sport. Connections between the left and right hand hemispheres of the brain are quicker in left-handed people. They are more comfortable in using both the sides of the brain. They are also better at multitasking and performing complicated jobs than right-handers as there is fast transfer of information in the brain. Study leader Dr Nick Cherbuin from the Australian National University calculated transfer time between the two sides of the brain by measuring reaction times to white dots flashed to the left and right of a fixed cross. Tests conducted on 80 right-handed volunteers showed there was a strong correlation between how quickly information was transferred across the left and right hemispheres and how quickly people spotted matching letters. But when the tests were repeated in 20 left-handed volunteers, the researchers found that the more left-handed people were, the better they were at processing information across the two sides of the brain. They were 43 milliseconds faster spotting matching letters across the right and left visual fields than right-handed people. Dr Cherbuin concluded: “These findings confirm our prediction of increasing efficiency of hemispheric interactions with increasing left-handedness

Herbs and shrubs are always known for their medicinal values, but the shrub called the Artemisia annua, is broadly regarded by medical experts as the best cure for malaria, one of the world’s leading deadly diseases. Sweet Wormwood (Artemisia annua) is distinguished from other kind of shrubs by its fresh, sharp scent. This shrub with fern-like leaves first found its way into Chinese medical annals more than 1,600 years ago in Luofushan in China’s southern Guangdong province. Doctor Ge Hong was the first who, wrote about it in his Book of Emergency Medicine when he served as a Taoist priest in this mountainous region.The WHO recommends that artemisinin be used in combination with other drugs, or artemisinin-based combination therapies (ACTs), to slow the development of any resistance.Quinine, extracted from the bark of the South American cinchona tree and in use for more than 160 years, was regarded as the drug of choice up to the early 2000s, until it was displaced by artemisinin in the controversial SEAQUAMAT (Southeast Asia Quinine Artesunate Malarial Trial) of June 2003-May 2005. Doctors in India, Bangladesh, Indonesia and Myanmar split 2,000 patients suffering from severe malaria into two groups, giving half of them artemisinin and the other half quinine but stopped the trial because of the huge difference in mortality in the two groups.
Insomniacs can breath a sigh of relief as scientist have found out new ways to deal with insomnia. Researchers studying a disease that causes people to suddenly fall off to sleep are trying to turn what they have learned into a new way to help insomniacs get some shut-eye. According to a paper in Sunday’s online issue of the journal Nature Medicine- Researchers found that blocking brain receptors for orexin, a blood peptide, promoted sleep in rats, dogs and people. Orexin (hypocretin) is important in maintaining wakefulness. It is missing in the brains of people who experience narcolepsy, a chronic disorder in which people cannot regulate sleep-wake cycles normally. The research team, led by Francois Jenck of the Swiss drug company Actelion Pharmaceuticals, developed a drug that can block the receptors in the brain that respond to orexin-hypocretin. The researchers reported successful testing in rodents, dogs and men. Researchers hope to decide this year whether to conduct a phase-three study, a detailed assessment of the drug that would be the final step before seeking U.S. government approval for its use. Dr. Thomas Scammell, professor of neurology at Harvard University, said the work was “promising, with a certain amount of caution. I think it may be the beginning of something quite exciting.”
Carnegie Mellon University scientists have married bright fluorescent dye molecules with DNA nanostructure templates to make nanosized fluorescent labels that hold considerable promise for studying fundamental chemical and biochemical reactions in single molecules or cells. According to Armitage- The high brightness of the nanotags should be of very helpful in detecting rare cancer cells within tissue biopsies, for example, which is important in determining whether treatments have been successful or if recurrence is likely. In addition, DNA nanotags offer the opportunity to perform multicolor experiments which is useful for imaging applications, as the multiple colors can be seen simultaneously, requiring only one experiment using one laser and one fluorescence-imaging machine. The scientist modeled their DNA nanotags on the structure of phycobiliproteins. Found in certain types of algae, these proteins contain multiple, fluorescent pigments that work together to absorb light energy that is then transferred to chlorophyll, where it is used for photosynthesis. The Carnegie Mellon team assembled well-defined nanostructured DNA templates that bind multiple fluorescent dye molecules between base pairs in the DNA helix to achieve greater brightness. DNA nanotags contain “light-harvesting” dyes within the DNA helix that are excited by one wavelength of light and then transfer that excitation energy to “light-emitting” dyes on the nanotag’s surface which made multicolor experiments possible.
Most of the times we avoid dental visits as we are scared of the pain the drills and needles will give us. But what if we could have our fillings placed painlessly without drills or needles? Air abrasion is a drill-less technique that is being used by some dentists to remove tooth decay and for other applications. Micro-fine particles are sprayed against the tooth in a very fine ‘particle beam’. These particles gently blow away tooth decay. An instrument that works like a mini sandblaster is used to spray away decay. During air abrasion, a fine stream of particles is aimed at the decayed portion of the tooth. These particles are made of silica, aluminum oxide, or a baking soda mixture and are propelled toward the tooth surface by compressed air or a gas that runs through the dental hand piece. Small particles of decay on the tooth surface are removed as the stream of particles strikes them. The particles of decay are then “suctioned” away. Compared with the traditional drilling method, the advantages of air abrasion are- it generates no heat, sound, pressure or vibration, reduces the need for anesthesia, reduces the risk of micro fracturing and chipping of the tooth and hence prevents the need for future crowns and even root canals. The procedure is relatively simple and quick.
