...h uses both high and low frequency sound waves, to differentiate between solid and gaseous emboli during carotid artery stenting and angiography. "Microembolization" frequently occurs during stenting even with deployment of a distal protection device, the researchers found. More solid emboli (clots) were seen du...Cord blood cells proven to differentiate into heart muscle and brain cells
...lood-forming and immune systems, and that they can differentiate themselves into brain, heart, liver and bone cells...their new surroundings and respond to signals that differentiate them into the needed kind of cell. Indeed, it appears that donor stem cells inexplicably home in on ...Reprogrammable cells from fat are true adult stem cells
...ast two different paths, only 10 percent failed to differentiate into any of the four cell types, Lott said. "Additionally, the results of this study offer criteria for defining stem cell multipotency that should help researchers in further investigations," Guilak said. "More of the clones developed into bone, ca...Progenitor cells predict heart disease severity
...s or by retraining the patient's own stem cells to differentiate into progenitor cells capable of arterial repair. While the direct clinical use of stem cells as a treatment might be many years off, the researchers said it is likely that strategies currently used to reduce the risks for heart disease -- such as li...Stem cells appear not to turn into heart cells
... cells appeared to survive, they did not appear to differentiate into new heart muscle cells. Instead they matured into cells of the traditional blood lineage....Nanotech imaging, molecular fingerprints and signatures hold promise for cancer
...cancer and advance the quest to provide a means to differentiate between early and late stage ovarian cancer in women. Mehta and colleagues examined proteins and peptides that travel in the blood attached to albumin, a large 'sticky' serum protein that acts as a carrier of bioactive molecules. By comparing...Jefferson researchers discover novel gene profile that may identify colon stem cells
...te and make their way to the crypt top, where they differentiate into specialized colon cells, says Dr. Boman. Colon cancer is marked by a change in the distribution pattern of proliferating daughter cells. Next, the researchers plan to use their novel gene profile to investigate cellular changes in colon cancer d...When 'switched on' muscle stem cells morph to resemble nerve cells
...tem cells go through a series of steps before they differentiate into neurons, and each step is initiated by expression of different sets of genes. The last step, in which a large number of genes are activated, is only made possible when a repressor gene -- a kind of brake known by the acronym REST/NRSF -- is abse...CNS cancers and other diseases: Using proteomics to identify unique protein 'fingerprints'
...rospinal fluid (CSF) of humans that enable them to differentiate between cancers, both primary and metastatic, and non-cancerous diseases of the central nervous system (CNS). This finding offers promise of a more rapid, less invasive, and more accurate method of diagnosis of CNS diseases, especially the difficult-...First randomized trial of adult stem cell injections in heart failure patients shows benefit
...rom heart attack or chronic illness could feasibly differentiate into heart muscle cells and cells that promote new vessel growth, thereby improving the heart's ability to contract more effectively and restoring blood supply to the heart itself. The study involved 20 patients with severe heart failure (New York H...Malaria: Plasmodium togetherness a strategy for breeding success
...ground the fly's stomach provides. The gametocytes differentiate into gametes that possess no particular means of attraction, so this lover's ritual of clustering is a sophisticated parasite reproduction strategy which compensates for its gametes' lack of attraction mechanism. Further research is planned, with thr...Dental pulp cells may hold key to treatment of Parkinson's disease
... neurotrophic support for dopaminergic neurons and differentiate into neurons in vitro, implications for tissue engineering and repair in the nervous system." Nosrat's co-authors are his wife, Irina Nosrat, Christopher Smith and Patrick Mullally, at the U-M School of Dentistry, and Lars Olson at the Karolinksa Ins...Researchers define mechanism that enables stem cells to track migrating brain tumor cells
...cells "immature" cells that have the potential to differentiate into any of several types of central nervous system cells have the ability to track glioma cells as they migrate. In recently published work, the researchers genetically engineered tumor-tracking stem cells to secrete interleukin 12, which elicited ...CAD system shows promise as adjunct to breast MRI
... media highlights the lesion over time) could help differentiate benign from malignant lesions. However, this study observed otherwise, said Dr. Chen. "Our study showed no significant differences between enhancement profiles of the benign versus malignant lesions," she said. "It is important to note again that thi...Cutting-edge science offers improved care for liver diseases
...mbilical cord blood cells may have the capacity to differentiate into functional liver cells after transplantation into humans," said Sei Kakinuma, M.D., Ph.D., lead author of the study. "These cells could be a potentially valuable source of cell transplantation, which could have an enormous positive effect on bo...Key immune system protein reduced in HIV-associated dementia patients
...i-bacterial enzyme found in human monocytes (which differentiate into macrophages), which circulate in the blood stream but migrate as macrophages to the brain and other organs to fight infection. Monocyte/macrophages are known to become infected by HIV in the bloodstream, but unlike the immune system's T-cells, t...Cells from fat tissue turned into functional nerve cells

These cells, they s...ue there is a population of stromal cells that can differentiate into different types of cells with many of the characteristics of neuronal and glial cells," said Du...Different subgroups of alcoholics respond differently to serotonin-acting medication
...erous classification schemes have been proposed to differentiate types of alcoholics. Our study supports the usefulness of the Babor Type A and Type B classification system. If we can identify subgroups that may have different post-treatment outcomes, then clinicians may be able to make more precise ongoing trea...Livermore scientists join DOE consortium
...plant in 2002 was able to see large letters and to differentiate between a cup, a plate and a knife after being blind for more than 50 years. To date, six volunteers have received implants of a micro-electronic device that rests on the surface of the retina to perform the function of normal photoreceptive cells. ...DOE labs, universities and second sight partner to speed development of 'artificial retina'
