New study reports hotel guests at risk from carbon monoxide poisoning

...cidents, 711 guests, 41 employees or owners and 20 rescue personnel were accidentally poisoned. Of those poisoned, 27 died, 66 developed pathological conditions, and 6 had conditions resulting in a jury verdict. Jury verdicts have averaged $4.8 million per incident (range=$1 million-17.5 million). Poisoning...

Researchers shed light on shrinking of chromosomes

...uch chromosomes and acts as a back-up mechanism to rescue separation defects.” The EMBL researchers found that an enzyme called Aurora kinase is crucially involved in this process. Blocking this enzyme abolishes late condensation of chromosomes. They now hope to uncover the detailed molecular mechanism un...

Penn researchers link cell's protein recycling systems

... proteins and have succeeded in using this link to rescue neurodegenerative diseases in a simple animal model. The study appears this week in Nature. The cell has two internal pathways for breaking down proteins. The ubiquitin-proteasome pathway marks unwanted proteins with ubiquitin tags and shuttles t...

Scientists identify molecular cause for one form of deafness

...just a fraction of normal espin linkers, a kind of rescue attempt at restoring hearing could, in principle, be made. "We have identified the underlying molecular cause for one form of deafness, and we have identified a mechanism to potentially 'rescue' this particular kind of pathology," Wong said. "Even ...

Mutation improves memory, may lead to memory-enhancing pill

...his way wouldn't cure the disease itself, it might rescue the symptoms of memory loss." Memories are formed when the repeated activation of brain cells leads to a strengthening of neural connections, or synapses. This process, considered the cellular basis of learning and memory, is known as synaptic pla...

Penn researchers replace organ in adult mice using 'single-parent' stem cells

...s with entirely uniparental blood and were able to rescue other irradiated mice with bone marrow transplants from these animals. It is clear proof, according to McLaughlin, that uniparental cells could produce hematopoietic stem cells. In addition, McLaughlin's group found no evidence of disease linked to...

Stem cell therapy shows promise for rescuing deteriorating vision

...e cells alone demonstrated a remarkable ability to rescue vision. "On their own, they were able to support retinal cells and keep them alive," says Lund, who has conducted pioneering studies of cell therapy for eye disease. "We didn't expect that at all. We've used a number of different cell types from d...

Prion disease treatable if caught early

...y and therapies to earlier stages of disease, when rescue is still possible. "Eventually it may also enable preclinical testing of therapeutic strategies through cognitive endpoints. These data now lead to the hope that early intervention in human prion disease will not only halt clinical progression but...

Transplanted brain cells hold promise for Parkinson's disease

...rk. An important question that remains is, ‘Can we rescue neurons that are dying from Parkinson’s"?This would more accurately mimic what patients need." The researchers already have begun studies that delay the transplants until weeks after injury. For this study, researchers compared animals that receiv...

Batfish to the rescue!

...arauder has emerged unexpectedly from the ocean to rescue a dying coral reef from destruction in the nick of time. With the dramatic flair of comic-book superhero Batman, a batfish has saved a coral reef that was being choked to death by seaweed ?although the fish was never previously known as a weed-eater...

Paying attention sets off symphony of cell synchronization

...a symphony of brain activity that can come to your rescue as millions of neurons together make the music that represents a vivid conscious experience," added Ken Paller, professor of psychology at Northwestern and co-investigator of the study. ...

MIT finds most complex protein knot ever seen

Study shows frogs can play key role in stem cell research

...s from such an ancient animal such as the frog can rescue the behaviour of 'modern' mouse embryonic stem cells. It told us so much about where this behaviour comes from, and how long ago," said Dr Morrison. Dr Josh Brickman, group leader at the Institute for Stem Cell research said: "Our results show that ...

When the going gets tough, slime molds start synthesizing

...lds not make DIF-1 but they couldn't construct the rescue tower, which was exactly the biological corroboration that the Noel lab wanted to hear. The two labs pooled data and now publish their work as one, very complete story while continuing to collaborate on the chemical diversity found in this fascinatin...

Parkinson's disease mechanism discovered

...s. Their studies have also identified a new way to rescue dying neurons in several animal models of Parkinson's disease. According to the researchers, the findings offer a promising opportunity for developing new drugs to treat the underlying causes of Parkinson's disease and related neurodegenerative diso...

'Prosthetic' retinal cells let blind mice see light

...ion has raised some concerns for the retinal-based rescue strategy after the death of photoreceptors," wrote Pan and colleagues. "However, retinal degenerative diseases are heterogeneous as to the time course of the degeneration, survival cell types, and, possibly, their functional state. Therefore, further...

Study fishes out new role for prostaglandins

...some prostaglandin back in the culture medium, you rescue the phenotype." In another set of embryos, the researchers blocked prostaglandin receptors, EP2 and EP4. Blocking the EP4 receptor caused defects similar to those associated with blocking PGE2 synthesis. When the researchers analyzed cell movement,...
