Nuclear Magnetic Resonance with a Levitating Microparticle.

Nuclear magnetic resonance (NMR) spans diverse fields from biology to quantum science. Employing NMR on a floating object could unveil novel possibilities beyond conventional operational paradigms. Here, we observe NMR within a levitating microdiamond using the nuclear spins of nitrogen-14 atoms.

Epidemiology of Tomato Brown Rugose Fruit Virus (ToBRFV) in Commercial Greenhouses.

The tomato brown rugose fruit virus (ToBRFV) poses a considerable threat to tomato production worldwide. Substantial experimental evidence supports the role of infected seeds as a contamination route, but the epidemiologic portrait of the virus has received less attention. This study reports the first survey of ToBRFV prevalence in commercial greenhouses.

Serum and urinary 5-hydroxyindolacetic acid, serotonin, chromogranin A, and NT-proBNP for the detection of carcinoid heart disease.

Objective: The aim of this study was to evaluate the performance of different biomarkers for the detection of carcinoid heart disease (CHD) in neuroendocrine tumours (NETs), in particular serum 5-HIAA (s5HIAA).

Design: An explorative ancillary study of the French CrusoeNET cohort.

Methods: Patients managed in the Lyon-EURACAN Center of Excellence (CoE) were included when they were aged of at least 18 years, treated and followed for an advanced/metastatic ileum or lung NET, a NET irrespective of the primary location or from unknown primary location but with clinical CS, and/or elevation of urinary 5-HIAA (u5HIAA) twice greater than the upper limit of normal.

Investigating MerR's Selectivity: The Crosstalk Between Cadmium and Copper Under Elevated Stress Conditions.

Bacteria respond to metal pollution through sensors that control the uptake and the detoxification machineries. Specificity in metal recognition is therefore a prerequisite for triggering the appropriate response, particularly when facing a mixture of metals. In response to Cu, the purple bacterium induces the efflux Cu-ATPase CopA by the Cu regulator CopR.

Oxaliplatin-Based Versus Alkylating Agent in Neuroendocrine Tumors According to the O-Methylguanine-DNA Methyltransferase Status: A Randomized Phase II Study (MGMT-NET).

Purpose: Alkylating agents (ALKY) are the main chemotherapies used for advanced neuroendocrine tumors (NETs). O-Methylguanine-DNA methyltransferase (MGMT) status, as proficient (p) or deficient (d), may predict the response to ALKY.

Patients And Methods: MGMT-NET (ClinicalTrials.
