Panel Calls for Biomarkers in Routine Clinical AD Diagnosis

Clinicians should try to incorporate biomarker data in their diagnosis of patients with Alzheimer’s disease or conditions potentially leading to it, an ad hoc expert panel recommended.

Levels of beta-amyloid or tau proteins in cerebrospinal fluid (CSF), or data from MRI or PET scans using amyloid-specific tracers, should be part of the differential diagnosis of Alzheimer-related disorders, according to two dozen members of the International Working Group for New Research Criteria for the Diagnosis of Alzheimer’s Disease.

Consortium Develops Algorithm from Blood-Based Alzheimer’s Biomarkers

Chronix Biomedical Adds State-of-the-art Mass Seqeuncing Capabilities to Accelerate Development of it’s DNA Biomakers for Early Detection of Cancer

Chronix Biomedical today reported that it has significantly expanded and accelerated its biomarker development capabilities with the installation of Germany’s first state-of-the-art high-throughput DNA mass sequencer at the University of Göttingen, Chronix’s long-time collaborator. Chronix is developing disease-specific biomarkers based on DNA fragments that are released into the bloodstream by damaged and dying (apoptotic) cells. Chronix‘s serum DNA biomarkers are applicable to a wide range of cancers and other chronic diseases.

The Cancer Biomarker Conundrum: Too Many False Discoveries

The boom in cancer biomarker investments over the past 25 years has not translated into major clinical success. The reasons for biomarker failures include problems with study design and interpretation, as well as statistical deficiencies, according to an article published online August 12 in The Journal of the National Cancer Institute.
