Shock it to Heal!!

...isguise would be a new device that delivers a high voltage electric current to the skin. //Such an electrical stimulation would help in the healing of foot ulcers. People with diabetes may develop foot ulcers as a result of poor circulation and a reduced ability to fight infection. The conventional way to t...

Testing Your Health & Charging Your Mobile At One Go - Check Out The Urine Powered Batteries

... The urine-powered battery was able to generate a voltage of about 1.5 volts - with a corresponding power of 1.5 micro-watts - using just 0.2 millilitres of urine. And if a second droplet of urine was added 15 hours after the battery was first activated, the replenished urine could generate still more elec...

Combination therapy for patients treated with Implantable Cardioverter Defibrillator

...r defibrillator (ICD). ICD treatment produces high voltage shocks which are used to treat fatal cases of ventricular arrhythmias, but these shocks are very painful which can be reduced by amiodarone drugs. Beta blockers such as sotalol is also used for treating shocks, the researchers have combined both th...

Radiation Therapy Made More Compatible

...duced by specialized x-ray tubes of extremely high voltage and current,’ Dilmanian said. Such x-ray sources may become available sometime in the future and may allow the implementation of the method in hospitals. Next, the scientists demonstrated the ability to "interlace" two parallel arrays of the thicker ...

EC Warns Tan Lovers Against Skin Cancer

...ars," the Commission warned. EU rules require low voltage devices to be safe and the Commission will request member states and the tanning industry to ensure that there are warnings to avoid misuse. The executive will also direct agencies that certify products to introduce ultraviolet radiation limits. The...

Samsung Develops Device to Measure Body Fat

...end a safe current through the body, measuring the voltage drop as the current flows up one arm and down the other. A body fat value serves as a main index to determine fatness, which is known to cause many adult diseases. Since fat occupies 17 percent of a human body and contains little water, it offer...

...y's Advanced Photon Source, where the accelerating voltage ranges from one to 20 keV, says Brinker. Genetic modification done cheap It is noteworthy that the entrapped cells easily absorb other nano-components inserted at the cellular interface. Because of this, the cell can internalize new DNA (introduc...

Researcher Develops Sensor to Detect E.coli

...end of the glass is a ceramic layer that generates voltage in response to applied mechanical stress. A voltage is applied to the ceramic layer, making it expand and contract, causing the glass sliver to vibrate....

Indian radiologist spearheads cure for osteoarthritis sans surgery

...ed and focused on to tissues, generating streaming voltage potentials. The electrical impulse in the joints causes forced movement of hydrogen protons and stimulates the cartilage called chondrocytes. "The trials have demonstrated that RFQMR stimulates the chondrocytes and initiates the regeneration proc...

Einstein's Tea Leaves Inspire New Blood Separation Technique

...d close to the surface of the blood at an angle. A voltage is applied to the needle, generating ions around its tip that repel the oppositely charged ions close to it. This creates an airflow known as "ionic wind" that sweeps across the surface of the blood, causing it to circulate. The microscopic particles...

Researchers Discover Key to Body’s Ability to Detect Subtle Temperature Change

...ating the flow of charged ions and controlling the voltage gradient found between the inside and outside of every living cell. In the current study, Zheng and his colleagues focused on a group of ion channels called transient receptor potential (TRP) channels. In all, there are more than 20 TRP channels. Z...

Micro-jets for Painless Needle-free Injections

...s backed up by a piezoelectric crystal, and when a voltage pulse is applied to the crystal it moves forward and pushes the piston. This, in turn, pushes the drug in the form of a small jet which penetrates into the skin." The pulsed micro-jets are expelled at over 100 metres per second at volumes of just 2...
