Bones from blood: Scientists aim to break new ground on fractures

...if the creation of bone structures from stem cells proves viable, it might be used for cell-based therapies to repair bone defects and fractures. Ultimately, bone structures developed in this way could be used to make hip replacements more durable. "The participation of colleagues from Sociology and Philos...

Diabetes researchers pioneer islet cell xenotransplantation in primate studies

...ination. "This represents a major step forward and proves neonatal porcine islets can correct diabetes long-term in primates," said Drs. Korbutt and Rajotte. "To meet the needs of the millions suffering from type 1 diabetes, we must find new donor sources to allow large-scale application of islet cell tran...

New discovery: Molecular variation in one gene affects the growth of natural populations

... and reproductive performance. The present result proves that these differences between individuals also have repercussions at the population level. The role of Pgi is emphasised by the fact that variation in the other genes studied showed no connection to population growth. How strongly the differences ...

New drug could reduce tissue damage after heart attack

...bition within a couple of years. If the treatment proves safe and effective, we also aim to investigate its effectiveness in strokes. "It is likely that CRP contributes to tissue damage in a range of diseases in which CRP levels are greatly increased, and the inhibition of CRP may thus find broad applicat...

First human study confirms that immune cells can be a primary cause of bone loss in gum disease

...ctivation, RANKL expression by T cells and B cells proves to be one of the major stimuli of osteoclast precursor cells and, hence, bone loss through periodontal disease. ...

UF scientists restore sight to chickens with blinding disease

...online journal Public Library of Science-Medicine, proves in principle that a similar treatment can be developed for an incurable form of childhood blindness. "We were able to restore function to the photoreceptor cells in the retinas of an avian model of a disease that is one of the more common causes of ...

Connect the Quantum Dots

... the luminescence of a quantum dot. This research proves this important fundamental principle and lay the necessary groundwork for researchers to further improve its sensitivity, stability and reproducibility for biomedical applications. "Our method has a long-term impact on biomedical diagnostic applica...

Failure of 'scout cells' may lead to cancer in transplant patients

...imulate the memory T cells. If our hypothesis proves to be true, VanBuskirk says, it may one day be possible to identify transplant patients who are at greater risk for PTLD and to develop new therapies that prevent or treat the disease. ...

Plants tell caterpillars when it's safe to forage

...is strategy is obviously no use against a cow, but proves effective when the offender is a caterpillar and the summoned predator is a wasp. Just how much control such biotic factors exert over a forager's daily routine has remained an open question. But in a new study in the open access journal PLoS Biology...

Newborn screening can cause unnecessary parental stress

...e considerable parental stress, even when the baby proves negative on retesting, and that the stress could be alleviated by better education for parents and pediatricians. Psychologist Susan Waisbren, PhD and Elizabeth Gurian, MS in Children's Division of Genetics interviewed 173 families who had received ...

Fat stem cells being studied as option for breast reconstruction

...the growth of cancer cells. We certainly hope this proves not to be the case," Dr. Rubin cautioned. In 2001, researchers from the University of California Los Angeles and the University of Pittsburgh first reported that adult stem cells could be isolated from adipose tissue, more commonly known as fat. ...

Halving daily cigarette quota has no health benefit

...temporary measure in smoking cessation, this study proves quite clearly that the only safe way out of the risk caused by smoking is to quit, say the authors. They base their findings on more than 51,000 men and women, all of whom were aged between 20 and 34 at the start of the study. Participants wer...

West Australian fossil find rewrites land mammal evolution

...es are found in the human arm. "This new fossil proves that features of land-living tetrapods (four-legged vertebrates) evolved much earlier in their evolutionary history than previously thought," Mr Fitzgerald, a researcher in the School of Geosciences, said. "This means that humans can trace their evol...

How brain injury leads to seizures, memory problems

PNAS study reveals why organs fail following massive trauma

...icle in the August edition of Nature. "Our study proves for the first time that it is possible to identify the genetic and protein changes in specific immune cells that play a significant role in determining whether or not trauma is fatal," said Carol L. Miller-Graziano, Ph.D., professor of Surgery and of...

Exposure to dioxins influences male reproductive system, study of Vietnam veterans concludes

...sturbances in the human body. The study indirectly proves that BPH is an endocrine disorder." Regarding the decreased risk for BPH found in the veterans groups, Dr. Gupta cautioned that the finding should not be interpreted as a positive result. "It may be construed that a decrease in the risk of BPH ...

U-M researchers use nanoparticles to target brain cancer

...hensive Cancer Center. If nanoparticle delivery proves to be safe in humans, it will allow researchers to re-examine previously developed drugs that were discarded because they caused too many dangerous side effects in patients. By combining the drug with a contrast agent, researchers were able using ...

'Best of both worlds' -- Targeting a single gene could inhibit bone decay and stimulate bone growth

...he quality of bone even better. "Our discovery proves that inhibiting osteoclasts while simultaneously stimulating new bone formation can be done." Bone health is maintained by the balanced activities of osteoblasts and osteoclasts. The study shows that the inactivation of gene Atp6v0d2 in mice resu...
