Allergy to hair dye increasing

...ns to PPD on patch testing is increasing. This was confirmed in a recent survey in London, which found a doubling in frequency over six years to 7.1% in a clinic for adults with contact dermatitis. This trend has also been observed in other countries. Market research also indicates that more people are dyei...

Scientists find genes involved in the battle between Hessian flies and wheat

...he larvae, which then fight back, he said. This is confirmed by the Hessian fly larvae's increased production of enzymes triggered by their antioxidant genes in order to detoxify wheat anti-insect poisons. "Hessian fly larvae are under stress when they encounter resistant wheat plants," Shukle said. "This s...

Brown cancer biologists identify major player in cell growth

... restart cell division were unchanged. The team confirmed GABP's critical role in cell growth another way. Simply forcing dormant cells to make GABP, they found, was enough to rouse cells from their slumber and get them to grow again. "So we've found a new pathway to control cell growth," Rosmarin said. ...

Discovery could lead to better control of hemorrhagic fever viruses

...n's lab by HMS graduate student Sheli Radoshitzky, confirmed that TfR1 is also the receptor for the other three New World arenaviruses. (Abraham and Radoshitzky are both first authors on the study.) Expertise from Nancy Andrews, MD, PhD, an expert in iron metabolism at Children's, sped up the work. Althoug...

Anthrax attack posed greater potential threat than thought

...x individuals vaccinated against B. anthracis, two confirmed to have had anthrax, and 12 with no known B. anthracis exposure. The results: Immune responses occurred not only in subjects in or near the Daschle office but also in those elsewhere in the Hart building, or even outside the building; the extent o...

Study shows hope for early diagnosis of Alzheimer's

...ercent of the time). Alzheimer’s disease cannot be confirmed until a patient has died and his or her brain has been examined. Gold standard tests administered at world-class research facilities, such as Penn, have a 90-percent accuracy rate. However, most people are evaluated at community hospitals and clinics...

First-degree fetal heart block may be reversible

...tervention. "Given the high recurrence rate we confirmed in this study, close monitoring and the earliest possible marker is necessary," said Copel, who plans trials of other possible treatments. "Advanced block and permanent heart damage can occur within one week of a normal echocardiogram, even a weekly ...

Vasectomy may put men at risk for type of dementia

...nch a national study to see if her results will be confirmed in a larger population. "I don't want to scare anyone away from getting a vasectomy," Weintraub stressed. "It's obviously a major birth control alternative. This is just a correlational observation," she said of the dementia connection. "We need...

Elucidation of the genome for diabetics with DNA chips

... The key results of this first screening were then confirmed in more than 5500 French diabetic patients treated at Corbeil-Essonnes Hospital (Guillaume Charpentier) and Poitiers University Hospital (Samy Hadjadj) and in additional control subjects. These results demonstrate very strong associations between DT2...

The chimpanzee stone age

... imitation of humans by chimpanzees. This study confirmed that chimpanzees and human ancestors share for thousands of years several cultural attributes once thought exclusive of humanity, including transport of raw materials across the landscape; selection and curation of raw materials for a specific type o...

Breakthrough in understanding type-2 diabetes as key genes identified

...ngle-nucleotide polymorphisms. The researchers confirmed their findings by analysing the genetic makeup of a further 5,000 individuals with type-2 diabetes and a family history of the disorder, to verify that the same genetic mutations were visible in these individuals. Professor David Balding, co-auth...

Genes may determine success of hip replacement surgery

...nd deep infection. The authors conclude that if confirmed in other research, these findings could be used to predict long term success in patients undergoing hip replacement surgery. And they could also be used to develop targeted genetic treatments....

Scientists find new genetic clue to cause of Alzheimer's disease

...n Younkin, M.D., Ph.D., of the Mayo Clinic further confirmed the association of SORL1 variations and Alzheimer's. "We are seeing the gene implicated in multiple data sets, across ethnic and racial groups," says Farrer. He adds that the group was "encouraged and excited" by cell biology experiments that demon...

Dual gene therapy suppresses lung cancer in preclinical test

...oparticle had individually. The research team then confirmed these findings in the mouse studies. The nanoparticle delivery system, which the researchers have used for years, consists of a plasmid gene expression cassette loaded with DNA that encodes either the p53 or the FUS1 protein. This is wrapped tight...

Inflammation may play role in metastasis of prostate cancer

... said Gonias. In research using mouse models and confirmed in human tissue, the scientists observed that a protein kinase called IkB kinasea (IKKa) turns down the expression of a single gene called Maspin, which has well-established anti-metastatic activity in breast and prostate cancers. They found that th...

Amur leopard still on the brink of extinction, scientists say

...k census of leopard numbers. "The recent census confirmed once again that the Amur leopard survives on very shaky ground," said Pavel Fomenko, biodiversity conservation program coordinator at the Far-Eastern branch of WWF in Russia. Fomenko said encroaching civilization, new roads, poaching, exploitation...

Application of Genomatix in silico methods reveals novel cancer associated genes

...mental verification by siRNA knock-down and RT-PCR confirmed the in silico results. "I am delighted that an ever increasing number of scientists proof the validity of our concepts and experience the value of our integrated approach. This excellent work, carried out by researchers at The Conway Institute of th...

Sleep enforces the temporal sequence in memory

...eaded by Jan Born at the University of Lübeck have confirmed the widely held view that long-term memories are formed particularly during sleep, and that this process relies on the brain replaying recently encoded experiences during the night. The same research group now provides evidence that sleep not only st...

Re-analysis of cigarettes confirms tobacco companies increased addictive nicotine 11 percent

...rettes sold in Massachusetts from 1997 to 2005 has confirmed that manufacturers have steadily increased the levels of this agent in cigarettes. This independent analysis, based on data submitted to the Massachusetts Department of Public Health (MDPH) by the manufacturers, found that increases in smoke nicotine...
