No evidence that widely prescribed statins protect against prostate cancer
...Hall said. In this study, statin use was just a marker
for presence of other illnesses, she said. This study may inform that debate, however, by suggesting that any protective pathway offered by statins, if it exists, is not through androgen suppression. ...
New test improves detection of liver cancer
...t in the blood. For the detection of HCC, only one marker
(AFP) is generally used. However, this marker
has a low specificity and is frequently inadequate because of false-positive results. New blood ...
Aggressive therapy best for certain AML patients
...these patients. It was the first clinically useful marker
to be identified in cases of AML with normal-looking chromosomes, and it was found to predict a short remission and poor response to therapy. About 8 percent of AML patients with normal-looking chromosomes have the mutation. Studies done eight to ...
Molecule blocks gene, sheds light on liver cancer
...ase. This particular microRNA might also provide a marker
to help determine a patient's prognosis. The study, led by researchers at the Ohio State University Comprehensive Cancer Center, is published in the August issue of the journal Gastroenterology. Our findings essentially describe a new mechanism...

Nodal status is best predictor of outcome after neoadjuvant therapy for esophageal cancer
...adiotherapy for oesophageal tumours is a surrogate marker
of survival advantage, explain the authors. However, the study established that it was nodal status rather than attainment of pathological response that was the most significant determinant of prognosis. When individuals with complete pathological...
New blood test might offer early warning of deep belly fat
...suggests a potential role for RBP4 as a convenient marker
not only for type 2 diabetes but also for cardiovascular risk, they wrote. In addition, RBP4 may provide a mechanistic link between visceral adipose tissue accumulation and the increased metabolic and cardiovascular risks associated with it. Kahn sai...

Engineered blood vessels function like native tissue
...scle cells from bone marrow by using a fluorescent marker
protein and a tissue-specific promoter for alpha-actin, a protein found in muscles that is responsible for their ability to contract and relax. Although not yet strong enough for coronary applications, the UB groups tissue-engineered vessels ...
New 'asthma gene' could lead to new therapies
...e located on chromosome 17, and children with this marker
had higher levels of a new gene called ORMDL3 in their blood, which occurs in higher amounts in children with asthma. The presence of the disease-associated version of ORMDL3 increases the risk of asthma by 60-70 percent, the study suggests. "In te...

for prion infection, even before the onset of apparent clinical disease. In practice, however, it ...
Antibody linked to MS significantly higher in spinal fluid of blacks
...Louis An antibody frequently used as a diagnostic marker
for multiple sclerosis (MS) is present at greater levels in the cerebrospinal fluid of blacks with MS than Caucasians with the disease.The findings suggest that genetic differences among ethnic groups contribute to changes in the immune system, affec...
Alcohol abuse is in the genes
.... Beta-endorphins constitute a useful biological marker
to identify specifically those subjects who have a higher risk of developing alcohol abuse, the research claims. Regarding the results of this study, professor Rico states the following: alcohol-abuse prevention must consist of locating and identif...
Support for chromosomal theory of cancer found in cancers' development of drug resistance
... cells of a particular cancer have the same set of marker
chromosomes, a rogues gallery of normal chromosomes and stumps of chromosomes. Duesberg and UC Berkeley postdoctoral fellow Ruhong Li showed that the karyotype of drug-resistant cancer cells differs significantly from the karyotype of drug-sensitive ...
Researchers find gene that spurs development of the epididymis
...eveloping epididymis for inhibin beta A and for a marker
of activin activation Yaos team was able to show that inhibin beta A was spurring activity in the cells that form the walls of epididymal tube. Further study showed that a lack of inhibin beta A led to stasis in these cells. Without it, the cells ...
Fine particulate matter from traffic may influence birth weight

of the particles originating from traffic, and in particular from diesel vehicles. Earlier American Studies had already suggested that fine particulate matter might influence the birth weight. This recent study is the first study from Germany and W...
