A New Bioactive Cement For Facial Reconstruction the future

...lop methods in future for improving the material's mechanical properties by using smaller encapsulating beads that biodegrade at a predictable rate. NIST and the American Dental Association Foundation have conducted cooperative research on dental and medical materials since 1928. ADAF researchers focus on deve...

Hope After Spinal Cord Injuries

Fuel demand to be met by Bio-diesel

...ery day. Kumar, a professor in the department of mechanical engineering, said his 10-member team took five months to complete the project at a cost of Rs.350,000. Speaking about the benefit of bio-diesel, he said the fuel is more efficient than general diesel. It has 10 percent of inbuilt oxygen, which help...

Bionic muscles developed by scientists powered by alcohol and hydrogen

...tself supports the chemical reaction that leads to mechanical work; electrochemical circuits can act as nerves, controlling actuation; some energy is stored locally in the muscle itself; and, like natural muscle, the materials studied contract linearly."...

Mystery behind Complex Regional Pain Syndrome Unraveled

...as found that these areas were highly sensitive to mechanical and heat-induced pain and also showed decreased nerve fiber densities. In case of the controls they did not display these reductions at their pain sites. Hence the researchers concluded by saying that complex regional pain syndrome patients should ...

Satisfied Sexual Intercourse for Impotence men with Penile Prosthesis

...ons which were mostly due to prosthesis infection, mechanical failure or urinary retention. The researchers feel implanting a penile prosthesis is effective in erectile dysfunction patients to have a satisfied sexual intercourse but minor complications such as prosthesis infection are the main concerns for pe...

Heart Functions Being Redefined By Researchers

...esearch which pumps out blood through synchronized mechanical and electrical waves which travel from the apex of the heart to its base. The diastole function of the heart is more important than thought previously, according to Dr. Marek Belohlavek at the Mayo Clinic. The diastole functions are comprised of both...

Novel Biological Pacemaker Under Construction for Weak Hearts

Critically Ill Patients More At Risk Of Infection If Glucose Is Present In Their Lung Secretions

...ically ill patients in intensive care who required mechanical help with their breathing for more than 48 hours. The patients were drawn from medical and surgical specialties. Levels of glucose were measured in their blood samples and lung secretions (bronchial aspirates). The lung secretions were also routinel...

Have You Ever Wondered How We Perceive Different Sounds?

...ion of the inner ear, the hair cells transform the mechanical vibrations that enter the ear in the form of sound waves into chemical signals, which they then direct to the brain. It is surprising to know that some species, including birds, are capable of re-growing hair cells. However mammals lack the ability...

Intensive Care Patients More At Risk From Kidney Failure

The researchers had conducted a multinational, multicenter, prospective, epidemiological study of ARF that includes the large...

Pill might be able to reduce the damage loud noise does to your hearing

...s sound receptors -- hair cells, which convert the mechanical energy of incoming sound waves into nerve messages to the brain. As hair cells die off, hearing erodes permanently. So it makes sense to try to build up the ear's antioxidant defenses as a preventive step, and as a fast treatment after noise exposure...
