Reconstructing the historical synthesis of mauveine from Perkin and Caro: procedure and details

Scientific Reports, 2017
Mauveine, an iconic dye, first synthesised in 1856 still has secrets to unveil. If nowadays one wanted to prepare the original Perkin’s mauveine, what would be the procedure?

Titanium migration and bone response in loaded osseointegrated implants: ESEM‐EDX analysis in Macaca fascicularis

Journal of Periodontology, EarlyView.
Abstract Background Titanium nanoparticle (TP) migration into peri‐implant bone may influence osseointegration. It remains unclear how loading protocols may affect TP distribution. This study aimed to detect TP in the bone around implants undergoing different loading protocols in Macaca fascicularis.

N-(Pyrazin-2-yl)-4-toluidine

Acta Crystallographica Section E, 2008
The two aromatic systems in the title compound, C11H11N3, are inclined by 19.1 (1)°, whilst the angle at the central amino N atom is 130.3 (2)°. The amino group forms a hydrogen bond to the pyrazine N-4 atom of an adjacent molecule,

Synchronous Regeneration: Key Mechanism for Selective Reinnervation in Bilateral Vocal Fold Paralysis

The Laryngoscope, EarlyView.
This study investigates the mechanisms behind the success of selective laryngeal reinnervation surgery in bilateral vocal fold paralysis. In an animal model, the surgery promoted neuromuscular regeneration and restored coordinated vocal fold movement, with no misdirected potentials observed.

Enrichment of Hyaluronic Acid Binding Tumor Cells by Modulation of Selective Adhesion on Microgel Surfaces

Macromolecular Rapid Communications, EarlyView.
We have developed a thermoresponsive microgel system for the selective enrichment of hyaluronic acid‐binding tumor cells. By modulating the adhesion on the microgel surface via temperature changes from 37°C to 30°C, we demonstrate a novel proof‐of‐principle for separating these tumor cell from white blood cells, which has potential applications in ...

Cu‐Enhanced Medium‐Entropy TiZrCoCrMo Alloys: Balancing Superior Antibacterial and Osteogenic Properties for Orthopedic Implants

Rare Metals, EarlyView.
ABSTRACT This study introduces novel nonequiatomic TiZrCoCrMoCux (x = 0, 5, 10; at%) medium‐entropy alloys (MEAx) tailored for orthopedic implants, synergistically combining the biocompatibility of Ti‐based alloys, the wear resistance of CoCrMo alloys, and the antibacterial/osteogenic attributes of Cu. The alloy's microstructure, mechanical properties,

Histodynamics of Natural Killer Cells from a Healthy Donor Exposed to Exosomes from the Blood of Hepatocellular Carcinoma Patients

Makara Journal of Health Research
Background: Hepatocellular carcinoma (HCC) is the leading form of liver cancer and the second leading cause of cancer-related deaths globally. Exosomes in the HCC microenvironment can induce significant changes in natural killer (NK) cells during ...
