Gene therapy delivery of nerve growth factors reverses erectile dysfunction in animal model

...cancer. Even if a patient receives a nerve-sparing procedure during surgery, recovery from ED after radical prostatectomy may take a long time. In this study, which was led by Joseph C. Glorioso, III, Ph.D., chair of the department of biochemistry and molecular genetics, and Joel Nelson, M.D., chair of the...

Gene therapy study shows safety and statistically significant improvement in Parkinson's disease

'Virtual autopsy' helps identify drowning as cause of death

...ntional autopsy. In cases of suspicious death, the procedure does not damage or destroy key forensic evidence, as can happen during a conventional autopsy. In addition, MDCT can be used in situations where autopsy may not be feasible or is prohibited by religious beliefs. However, in most cases, MDCT would bes...

Focused ultrasound relieves fibroid symptoms in women

A noninvasive ultrasound procedure effectively shrinks uterine fibroids and significantly relieves fibroid-related symptoms in women, according to the results of a multicenter clinical trial reported in the June issue of the journal Radiology. Magnetic resonance-guided, focused ultras...

Students invent protective pouch to enhance cell therapy

...iologist can view and guide the minimally invasive procedure as it takes place. First, the doctor would insert the stainless steel outer stent, which would push out harmlessly on the elastic interior of the vein. Next, the doctor would insert the inner stent, surrounded by the porous nylon mesh. The inner sten...

Automatic identification of protein's critical features from the structure

...de Fisiologia Celular/UNAM, developed an automatic procedure that allows scientists for the first time to identify the critical elements of proteins from their shape exclusively....

Tissue engineered scaffolding allows reproduction of cartilage tissue

...udy appears in the journal Artificial Organs. The procedure was extremely successful in tested mice as the study found these scaffolds to be a far more effective means of regenerating cartilage than traditional therapy. The shrinkage of cartilage that occurs frequently in other tissue engineering methods, and...

Implanting dopamine generators in brain cells obtains improvement in Parkinson's in monkeys

...uman primates and for a longer period of time. The procedure involved implanting cell fragments extracted from the carotid body in the striate area of the brain. The carotid body is a small structure located at the bifurcation of the carotid artery, at the level of the neck. Its function is to control the rhyt...

Lighting up life: Cold Spring Harbor Protocols presents tips for creating glowing plants

...ld Spring Harbor Protocols this month—describes a procedure for nurturing mammalian cells for studies in cell division. Both of these publications join a growing library of high-quality methods from Cold Spring Harbor Protocols that span a broad spectrum of topics essential to researchers across many discip...

2 brains -- 1 thought

...d to mathematically pin down this diversity." This procedure resembles juggling with many unknown quantities and requires great computational power. Already in a network of 1000 neurons (where each neuron can be connected to any other) there are a million possible contacts between any two neurons and consequen...

Imaging techniques permit scientists to follow a day -- or four -- in the life of a cell

...g/cgi/content/full/2007/1/pdb.prot4657 , details a procedure to inject proteins into individual cells. The injected protein can be fluorescently labeled, so scientists can track the glowing protein with a microscope and observe what it's doing and where it's going inside the cell. This microinjection technique...

Drug-resistant bacterial infections serious complication after corrective eye surgery

...urse who underwent an "uneventful" bilateral LASIK procedure that resulted in 20/20 (right eye) and 20/70 (left eye) visual acuity. Within 2 weeks, he had developed an infection in his left eye that grew worse, despite treatment, until his vision was only 20/400. When the infection was cultured and found to be...

Cancer-killing invention also harvests stem cells

...therapy. When doctors remove a primary tumor, the procedure itself can release cancer cells into the bloodstream. King's device would grab those cancer cells and kill them, greatly reducing the possibility of metastasis. Associate Professor King envisions that the device would use a shunt similar to the t...

Wired for sound: How the brain senses visual illusions

...li, using an electrophysiological or EEG recording procedure that measures electrical activity of the brain through the skull. "In subjects who reported seeing a second flash, the ERP measurements showed a boost of activity within the visual cortex of the brain immediately after hearing the second sound,"...

Scientists discover new, readily available source of stem cells

...otic fluid specimens obtained for amniocentesis, a procedure that examines cells in this fluid for prenatal diagnosis of certain genetic disorders. Similar stem cells were isolated from "afterbirth," the placenta and other membranes that are expelled after delivery. Atala said a bank with 100,000 specimens...

UW launches study testing adult stem cells for heart damage repair

...(ACT34-CMI) Trial. The first patient underwent the procedure March 7. Because the study is randomized and "double-blinded," however, neither the patient nor the research physician knows if he received his own stem cells or a placebo substance. This trial is the first human Phase II adult stem cell therapy s...

Surgeons develop simpler way to cure atrial fibrillation
