Researchers discover inherited mutation for leukemia

...osition. However, usually only two or three people within a family are affected, making it difficult to do the genetic studies needed to find possible mutations, Plass says. The family examined in this research was identified by collaborator Henry Lynch at Creighton University. The researchers are n...

Innovative smallpox vaccine research study to be conducted at Case Medical Center

...it contains a more weakened form of the live-virus within the vaccine. “Because the vaccine is weakened, the side effects should be minimized enough to give the vaccine to all individuals, even those whose immune systems are suppressed,” says Dr. Salata. “Our hope is that the new vaccine will be a safer...

Brain inflammation may be friend, not foe, for Alzheimer's patients

...time about a balance of ‘good guys’ and ‘bad guys’ within the inflammatory process, either causing harm or alleviating the disease. The current work reinforces the idea that inflammation is not simply the bad guy that many people think it is.” The work could have ramifications for the development of a va...

Snoring in children might be an allergic type disease

...ring the first five years of life. 219 children within the original study group had rhinitis and of these, 213 could provide information on snoring. Almost 60% of these children snored at least once per week including 26% who snored more than three nights per week. This is a very high prevalence in five...

Loss of stem cells correlates with premature aging in animal study

...such as hair graying, hair loss, and osteoporosis, within three to four months. To be able to renew itself, most tissues have a reservoir of specific adult stem cells. These stem cells don’t divide as frequently as other cell types since they need to maintain the integrity of their DNA, and multiple div...

New study finds genetically engineered crops could play a role in sustainable agriculture

...“Bt crops” fared better in field trials than those within locales treated with chemical insecticides. “This is a groundbreaking study and the first of its kind to evaluate the current science surrounding genetically modified crops. The results are significant for how we think about technology and the fu...

U-M researchers discover gene switched off in cancer can be turned on

...me from one person to the next, and even the cells within a single tumor are not the same. Giving a single drug or drug combination to 500 people is setting ourselves up for failure, much like a one-size-fits-all clothing store would never succeed,” Reisman says. “Targeted therapies are now opening the ...

Physicist cracks women's random but always lucky choice of X chromosome

...cess both X chromosomes are brought close together within the cell. The Warwick researcher paper says that what happens next is that material for a "protein plug" then begins to gather around both of the XIST suicide genes on each X Chromosome. This starts a race between the two build ups of protein. Inevit...

Therefore, autophagy requires HDAC6 to work. They also show...
