A new century of Alzheimer's disease research

...ch people would develop the disease over time. One marker is AB. Although no one knows what the normal function of AB is, the Mayo Clinic researchers found that it could be measured in blood, and that levels of both AB40 and AB42 varied in people who developed the disease. What they discovered through thi...

Blood Protein may Hold Key to Why Healthy People Get Heart Attacks

...terol or C-reactive protein, a widely acknowledged marker of inflammation. The study noted that MPO changes low-density-lipoprotein (LDL) cholesterol into a harmful oxidized form that cause atherosclerosis and the 'bleach' produced by MPO damages the arteries directly, causing cell death and erosion of th...

Chronic Insomnia can Lead to Anxiety Disorders and Depression

...ers and depression. "Chronic insomnia is a state marker of both anxiety disorder and depression," Neckelmann said. "From a clinical point of view, these results imply that individuals reporting chronic insomnia, in addition to receiving adequate treatment for their sleep disturbance, should be carefull...

Cognitive Test Takers and Score Variation

...in-person variability could be a useful diagnostic marker in their own right. For example, he and other cognitive psychologists are discussing whether wilder fluctuations within one persons test scores are an early warning of mental decline....

New Asthma Gene Identified

...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 ter...

New Blood Vessels can Be Created from Bone Marrow Stem Cells: Study

...ourse of study, the researchers used 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, to develop the new method for isolating functional smooth muscle cells from bone marrow. Although the re...

...er and was planned with MRI-CT fusion and fiducial marker insertion, and treated with dose-escalated 7-field IMRT with online cone-beam CT and electronic portal image verification. "As a result of the technology now available at the NCCI, we will be able to provide patients with the most modern, highest q...

Genetic Marker That Increases Colon Cancer Risk Discovered

Boffins have discovered a genetic marker that increases a person's risk of colon cancer by ...ithout the marker. The genetic link between the marker and colon cancer was especially strong among patients diagnosed with colon cancer at a young age, le...

For prostate cancer patients whose tumors have continued to grow despite medical o...

Large Geographic Differences in EpiPen Prescriptions in the U. S.

...g north-south differences in EpiPen prescribing, a marker of anaphylaxis risk, currently are without explanation. The investigators hypothesize, however, that low levels of vitamin D from lack of sunshine, may play a role and that this hypothesis requires further investigation. The study, Regional differ...

Nodal Status is the Best Predictor in 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...

C -reactive Protein is the Marker for Cardiovascular Disease

...tudy of children ages 5 to 7,C-reactive protein, a marker of inflammation that is often used to detect cardiovascular disease, may also indicate cognitive impairment in children with obstructive sleep apnea. Children with OSA have increased levels of hsCRP [high-sensitivty C-reactive protein] and also e...

HIV Drug Combo can Boost Immune Marker in Long-term Patients: Study

The paper sheds light on poorly understood conditions as to why some people on antiretroviral drugs can boost and maintain th...

Alcohol Consumption may Help to Protect Against Rheumatoid Arthritis

...s to detect the presence of HLA-DRB1 SE alleles, a marker indicating genetic risk factor for RA, and all cases were classified by presence of anti-CCP2 antibodies (anti-cyclic citrullinated peptide antibodies) to identify RA subtypes. Researchers calculated gender-specific odds ratios for anti-CCP positiv...

Scientists Have Discovered Blood Protein That Could Spot Colon Cancer

...particular concentration of scaffold-proteins as a marker for disease. Researchers found 100 percent accurate results in identifying the 28 existing cancers, using the same protein markers. "These proteins seem very good at separating normal samples from cancerous ones and identifying other groups with ...

Women Taking Oestrogen Therapy Showed Reduced Coronary Artery Calcification
