Automated Patch Clamp for the Detection of Tetrodotoxin in Pufferfish Samples.

Tetrodotoxin (TTX) is a marine toxin responsible for many intoxications around the world. Its presence in some pufferfish species and, as recently reported, in shellfish, poses a serious health concern. Although TTX is not routinely monitored, there is a need for fast, sensitive, reliable, and simple methods for its detection and quantification.

Comparative Study of 2D-Cine and 3D-wh Volumetry: Revealing Systemic Error of 2D-Cine Volumetry.

This study investigates the crucial factors influencing the end-systolic and end-diastolic volumes in MRI volumetry and their direct effects on the derived functional parameters. Through the simultaneous acquisition of 2D-cine and 3D whole-heart slices in end-diastole and end-systole, we present a novel direct comparison of the volumetric measurements from both methods. A prospective study was conducted with 18 healthy participants.

Evaluation of Toxicity Equivalency Factors of Tetrodotoxin Analogues with a Neuro-2a Cell-Based Assay and Application to Puffer Fish from Greece.

Tetrodotoxin (TTX) is a potent marine neurotoxin involved in poisoning cases, especially through the consumption of puffer fish. Knowledge of the toxicity equivalency factors (TEFs) of TTX analogues is crucial in monitoring programs to estimate the toxicity of samples analyzed with instrumental analysis methods. In this work, TTX analogues were isolated from the liver of a individual caught on South Crete coasts.

The efficacy of the dental Water Jet, orthodontic, and conventional toothbrushes in plaque removal around orthodontic braces in adolescents: A randomized controlled trial.

Objectives: Orthodontic treatment improves both masticatory function and the aspects of facial esthetics through the correct alignment of the teeth. If oral hygiene is neglected during fixed orthodontic treatment, it may lead to plaque accumulation and gingivitis. The aim of this randomized controlled trial was to evaluate the effectiveness of the dental Water Jet (DWJ), and orthodontic toothbrush (O-TH) in removing dental plaque around the orthodontic braces compared to conventional toothbrush (C-TH) in adolescents.
