Stem cell study for patients with heart attack damage seeks to regenerate heart muscle

...rough a standard IV line. Other therapies require delivery to the site of the disease through catheterization or open surgical procedures, but this one is very simple and easy for the patient. "A person who has had a single, severe heart attack may survive but can be left with substantial damage to the hear...

Botox could help target resistant tumors for treatment

...of its use as an adjuvant, assisting the effective delivery of chemotherapies and radiation. The findings mark a relatively new area of cancer research, which focuses on briefly opening blood vessels that feed tumor cells in order to better deliver therapeutic agents. Until recently, much cancer research has...

New antimicrobial compound adheres to skin to promote healing

...harmacy who specializes in the formulation of drug delivery systems. The first noteworthy application of the Tricide bioadhesive came last year in the treatment of Spirit, the Athens-area dog that was deliberately set on fire. The researchers are currently using the compound to heal skin ulcers on a whale n...

Scientists force viruses to evolve as better delivery vehicles for gene therapy

...y other characteristics of AAV to make it a better delivery vector for genes. "We think there are a huge variety of new problems we could address as well, such as targeting the virus to cells it is ordinarily not good at getting into, or speeding its transport through the body," he said. Though Schaffer ack...

Efficiency, not more doctors, is the prescription for aging population

...resources might be better directed to reorganizing delivery systems that have already demonstrated that they can deliver good care at relatively low cost," the authors write. ...

Nano-particles effective in killing cancer with one-two punch of chemotherapeutics

...r of advantages over other Trojan horse-style drug delivery system, and should prove a useful tool in fighting a number of diseases," said Dennis Discher, a professor in Penn's School of Engineering and Applied Science and a member of Penn's newly established Institute for Translational Medicine and Therapeut...

Radiation-armed robot rapidly destroys human lung tumors

...st US teams devoted to the CyberKnife, a radiation delivery system that uses an accurate, precise robotic arm to aim highly focused x-ray beams at the site of a tumor. Currently there are 76 active CyberKnife sites worldwide (with 45 in the US), and an additional 62 scheduled to be installed globally. Rece...

Viagra improves high altitude exercise performance up to 45% for some

...en from the lungs to the blood and improved oxygen delivery to working muscles. The participants, all trained cyclists, performed a total of 10 cycling trials, with and without sildenafil at sea level and at simulated altitude of 3,874 meters. Neither the participants nor the researchers knew whether the tri...

UC Davis researchers move biotechnology closer to replacing electronic pacemakers

...ccessfully used a custom designed protein and gene delivery system to restore normal heart rhythms in pigs with electronic pacemakers, reducing their dependence on implanted devices. This work suggests that scientists are one step closer to making bioengineering a reality in treating the more than 2.2 million...

UF scientists restore sight to chickens with blinding disease

...tions of sight." Work remains to refine the viral delivery system that transfers the healthy genes to the photoreceptor cells. In addition, solutions have to be found to make the treatment long-lasting -- scientists have restored sight and slowed degeneration, but the retinal cells still degenerate. But Sem...

Bubbles go high-tech to fight tumors

...Gas bubbles, on the other hand, allow very precise delivery because their formation can be controlled and directed from the outside, by a focused high intensity ultrasound. This envisioned technique is actually a two-step process, Bull said. First, a stream of encapsulated superheated perfluorocarbon liquid...
