Study Shows Varied Results from Different Methods of Measuring Albumin

A recent paper compared the accuracy of several different methods for determining levels of serum or plasma albumin, measurements, which are used to evaluate the nutritional status, kidney function, and fluid balance of dialysis patients. More...

Low Levels of Klothos Linked to Kidney Function Decline

The kidney has the highest levels of klotho expression and is likely the major source of soluble klotho and not surprisingly, therefore, levels of klotho tend to be low in patients with kidney disease. More...

Screening System Detects Four Metabolic Disorders

Lysosomal Storage Disorders (LSDs) are a group of rare, inherited metabolic disorders in which enzymes (proteins) that normally eliminate unwanted substances in the body’s cells are not at normal levels or functioning properly. If not detected and treated in a timely manner, these disorders may cause organ damage, neurological disability or death. More...

Increased Triglyceride Content Associated with Plasma Lipoprotein Lipase

Non-fasting plasma triglyceride (TG) reflect a higher risk for cardiovascular disease (CVD) than TG in the fasting plasma and this the postprandial increase of TG is the most common form of hyperlipidemia which is associated with increased remnant lipoproteins (RLP) as a risk factor for CVD.

Novel Approach Enables Ultrasensitive Detection of Volatile Organic Compounds

By a pore tuning approach using anisotropically shaped sno2 nanocrystals, scientists have developed highly sensitive gas sensors for volatile organic compound (VOC) detection. More...

Genome Study Strengthens Value of PSA Screening as Diagnostic Tool

Results of a genome-wide association study (GWAS) of prostate specific antigen (PSA) may lead to improvements that will increase the usefulness of measuring this biomarker for diagnosis of prostate cancer. More...

Blood Test May Help Predict Confusion Post-Surgery

Many people experience an extended period of confusion when they awake after surgery and this acute confusional state, called delirium, particularly affects older adults and poses an important clinical challenge as it can lead to greater postoperative complications and may extend hospitalization.
