New MS-Based Technique Detects Drugs in Urine Samples
The rapid urine test can detect 40 drugs reliably in just three minutes and can also be applied in clinical toxicology tests
Scientists Close in on Elusive Goal of Adapting Nanopore Technology for Protein Sequencing
Technology could enable medical laboratories to deploy inexpensive protein sequencing with a handheld device at point of care and remote locations
“Zombie neurons” shed light on the cerebellum's critical teaching signals
Nestled at the back of your head, the cerebellum is a brain structure that plays a pivotal role in how we learn, adapting our actions based on past experiences. Yet the precise ways in which this learning happens are still being defined. A study led by a team at the Champalimaud Foundation brings new clarity to this debate, with a serendipitous finding of so-called "zombie neurons". These neurons, alive but functionally altered, have helped to advance our understanding of the cerebellum's critical teaching signals.
Approved Whole Blood Rapid Test for Assessing Brain Injury
US Army Announces FDA Clearance of Whole Blood Rapid Test to Help with Assessment of Traumatic Brain Injury
Liquid Biopsy Not Effective for Colorectal Cancer Screening
A blood test will be better than nothing, but may lead to more CRC cases and deaths than established screening tests
Muscles in microgravity: Spaceflight duration impacts muscle protein stress markers
Researchers analyzed muscle samples from long-duration mission (LDM) and short-duration mission (SDM) astronauts to investigate the effects of spaceflight on muscle protein nitrosylation. They found that LDM astronauts showed close-to-normal expression of sarcolemmal NOS1 (short for nitric oxide synthase type-1) and over-nitrosylation of functional proteins post- vs. preflight, indicating muscle adaptation. Further, SDM astronauts displayed s-nitrosylation of glycolytic flux proteins, tricarboxylic acid (TCA) cycle proteins, and respiratory chain proteins, indicating impaired adenosine triphosphate (ATP) production and muscle contraction.
San Diego University Researchers Believe Bacteriophages May Be the Future of Eradicating Multi-Drug Resistant Superbugs
Clinical laboratories and microbiologists may soon have new powerful tools for fighting antimicrobial resistant bacteria that saves lives
The effect of personality traits on over-the-top service use and binge-watching
With the freedom to consume content on preferred devices at any time as long as there is an Internet connection, binge-watching has become a prevalent behavior. The effect of personality traits on over-the-top service use and binge-watching is examined. Implications of the current findings and future research are presented.
Having a ruff day? Study says spending time with dogs can help
In a recent study published in PLoS ONE, researchers examined how interacting with dogs affects the emotions and psychophysiology of humans using an electroencephalogram (EEG).
