Metabolites Altered in Chronic Kidney Disease

Chronic kidney disease (CKD) is an important public health problem with a high prevalence worldwide, from 10% to14% of the general population, and strongly increased age-standardized death rate, yet, there is a paucity of effective treatment options. More...

Blood Biomarker Detected for Different Diseases

A method has been developed to identify biological markers in small amounts of blood that could be used to detect a myriad of diseases, infections and different medical conditions at early stages. More...

Diagnostic Test Identified for Pediatric Biliary Atresia

Biliary atresia is a rare disease of the liver and bile ducts that occurs in infants. Liver cells produce bile, which helps digest fat and carries waste products from the liver to the intestines. When an infant has biliary atresia, this flow is blocked and bile becomes trapped inside the liver, quickly causing liver damage and eventually liver failure. More...

Physicians Perform Fewer Prostate Biopsies Post-Phi Testing

Prostate cancer is the third-leading cause of cancer death in men, with one in seven receiving a diagnosis during his lifetime. In 2017, approximately 161,360 new cases of prostate cancer were identified, with 60% of those occurring in men 65 years of age or older. More...

Newly Developed Automated Immunoassay Analyzed

Dipeptidyl peptidase-4 (DPP-4) may be a suitable biomarker to identify people with severe asthma who have greater activation of the interleukin-13 (IL-13) pathway and may therefore benefit from IL-13-targeted treatments. More...

Test Detects Overdose Patients at Risk of Liver Damage

Paracetamol is a safe analgesic drug when taken at therapeutic doses; however, in overdose, paracetamol is hepatotoxic and is the most common cause of acute liver failure in the USA and Europe. More...

Image: Diagram of DiviTum sTK1 assay: BrdUTP is subsequently incorporated into a solid-phase DNA-strand. Incorporated BrdU is detected using an anti-BrdU monoclonal antibody conjugated to the signal generating enzyme alkaline phosphatase. The level of BrdU incorporated over time is proportional to the level of thymidine kinase activity in the sample (Photo courtesy of Biovica).

Blood Test Reduces Interim for Evaluating Cancer Treatment

Although prognosis and treatment of metastatic breast cancer (MBC) have improved over the last years, there is still an unmet clinical need for more precise prognostic and treatment monitoring tools. More...
