Triggering Collapse of the Presolar Dense Cloud Core and Injecting Short-Lived Radioisotopes with a Shock Wave. I. Varied Shock Speeds

, 2009
The discovery of decay products of a short-lived radioisotope (SLRI) in the Allende meteorite led to the hypothesis that a supernova shock wave transported freshly synthesized SLRI to the presolar dense cloud core, triggered its self-gravitational ...

Inhibition of Intestinal Cholesterol Absorption by Ocimum sanctum L. Flower Aqueous Extract via Changing Physicochemical Properties of Cholesterol Micelles

Journal of Food Biochemistry, Volume 2026, Issue 1, 2026.
Hyperlipidemia is recognized as a major contributor to chronic noncommunicable diseases. The primary strategy regarding hyperlipidemia prevention is involved in the blockade of intestinal cholesterol absorption. Ezetimibe (Eze) is the sole prescribed drug that targets Niemann‐Pick C1 Like 1 (NPC1L1), a key cholesterol transporter, resulting in reduced ...

Sc(III) Complexes of Pyclen Derivative Ligands as Probes for Hypoxia: Synthesis, Chemical Characterization, 44Sc‐Radiolabeling, and Preclinical Assessment

Chemistry – A European Journal, Volume 31, Issue 72, December 23, 2025.
Hypoxia‐sensitive nitroimidazole‐functionalized pyclen derivatives were successfully synthesized and radiolabeled with 44Sc(III), affording stable and inert scandium complexes. Remarkable Sc(III)‐binding capabilities of the PC2A‐mono(amide) platform enabled excellent radiolabeling performance, with ≥92–99% yields and ≥99% radiochemical purity. MicroPET
