Sclerostin expression in trabecular bone is down-regulated by osteoclasts

Scientific Reports

Bone tissues have trabecular bone with a high bone turnover rate and cortical bone with a low turnover. Expression of sclerostin by osteocytes works to inhibit bone formation. A study performed recently aimed to evaluate the relationship between the secretion of sclerostin by osteocytes and the secretion of leukemia inhibitory factor (LIF) by osteoclasts. It was found that LIF secretion effectively suppresses sclerostin expression and promotes bone formation.

Biomarker of urinary 5-HIAA as a valuable predictor of acute appendicitis

Science Direct

Acute appendicitis is one of the most common causes of severe acute abdominal pain globally. Increased levels of 5-Hydroxyindole acetic acid (5-HIAA), a metabolite of serotonin, in urine has been associated with acute appendicitis due to the densely packed serotonin-containing cells in the appendix. A study performed recently aimed to evaluate and determine the significance of 5-HIAA as a diagnostic marker.

Alzheimer’s targets brain cells that help people stay awake

Science News

New Alzheimer’s disease research is providing valuable insight into the cause of the drowsiness associated with dementias. A study performed in a neuropathology lab at UC San Francisco found the brain stem and hypothalamus to be packed with tau protein. The brain stem and hypothalamus oversee several nervous system functions, including keeping people awake and focused. Tau forms “tangles” inside of nerve cells and hinder them from performing necessary functions. In studying three areas of theses structures that help keep people awake, researchers found over 70 percent of the nerve cells were destroyed by tau. These findings will help to drive a greater focus on the brain stem in dementia and Alzheimers research.

Our Anti-Phospholipid IgM and IgG Line Immunoassays were used in two recent studies. These assays are part of our DotDiver line of products from Generic Assays (designed for use with the DotDiver 2.0 Immunoassay Processor).

The first study performed a comparison of the line immunoassays versus the ELISA method to evaluate the sensitivity and specificity. The second study focused on using line immunoassays to examine thrombotic risk of non-criteria anti-phospholipid antibodies. Abstracts and citation information for both studies are below.

Evaluation of the sensitivity and specificity of a novel line immunoassay for the detection of criteria and non-criteria antiphospholipid antibodies in comparison to established ELISAs. (Full Article)

Abstract Background:
Persistent antiphospholipid antibodies (aPL) constitute the serological hallmark of the anti-phospholipid syndrome (APS). Recently, various new assay technologies for the detection of aPL better suited to multiplex reaction environments than ELISAs emerged. We evaluated the diagnostic performance of such a novel line immunoassay (LIA) for the simultaneous detection of 10 different aPL.

Thrombotic Risk of Non-Criteria Anti-Phospholipid Antibodies Measured by Line Immunoassay: Superiority of Anti-Phosphatidylserine and Anti-Phosphatidic Acid Antibodies  (Full Article)

Abstract Background:
Increasing interest has focused on the development of new assays more specific for APS and application of multiple combinations of anti-phospholipid antibodies (aPLs). This study explored the thrombotic risk of non-criteria aPLs measured by a new line immunoassay (LIA) and the benefit of additional non-criteria aPLs results to the APS diagnosis.

Gluten response in celiac patients could lead to diagnostic test

Science Daily

A study led by ImmunastaT Inc. could provide significant advances in diagnostic testing for celiac disease. The current testing requires patients to ingest gluten over an extended period of time, sometimes up to several months, before having an invasive procedure to sample the small intestine. During this time, the patient will experience the symptoms related to celiac, including nausea, vomiting, diarrhea, and abdominal pain. The new test involves researchers testing for immune markers related to celiac disease in blood samples. Initial research shows that these markers are present and detectable in blood samples in just a few hours after gluten consumption. Interleukin-2 (IL-2) was found to be the most prominent cytokine to appear shortly after gluten ingestion. Researchers believe that celiac symptoms are caused by gluten-specific CD4+ T-cells are being reactivated by the presence of these markers.
