Bone ingrowth in randomly distributed porous interbody cage during lumbar spinal fusion.

Porous interbody cages are often used in spinal fusion surgery since they allow bone ingrowth which facilitates long-term stability. However, the extent of bone ingrowth in and around porous interbody cages has scarcely been investigated. Moreover, tissue differentiation might not be similar around the superior and inferior cage-bone interfaces.

TiAlV Implants with Dense-Trabecular Bilayer Morphology for Bone Ingrowth: Synergy of Green Net Shaping and Sacrificial Templating.

Stress shielding in dental and orthopedic implants is a long-standing hurdle, and trabecular porous architecture to improve bone ingrowth is deemed to be a potential solution. Fabricating TiAlV components with dense-porous bilayer structures is complicated with limited lab-scale and commercial success. Here, a green dough-forming technique with metal powders is successfully explored to develop heterogeneous structures with a monolith-like dense-porous interface.

6-Aminocoumarin-derived Schiff base gelators: aggregation and sensing of CN, Fe, Cu and CO under different conditions.

Herein, we report the synthesis, characterization, supramolecular gelation and multiple applications of 6-aminocoumarin-derived Schiff bases 1 and 2. Both Schiff bases underwent gelation in DMF-HO (2 : 1, v/v), DMSO-HO (2 : 1, v/v) and dioxane-HO (2 : 1, v/v) involving weak forces. Furthermore, the gels were stable and exhibited good viscoelastic properties.

Skeletal Reorganization Emanated via the Course of Heterocyclic N-N Bond Cleavage: Electrosynthetic Approach.

A unified method toward the synthesis of functionalized diazepines and quinazolines through reorganization of the molecular skeleton has been devised. The process is indulged by electrical energy via a domino N-N bond cleavage followed by concomitant ring closing, initiating from cinnolines and indazoles as designed precursors. Additionally, an intermolecular ring homologation has also been established to synthesize densely functionalized dihydroquinazolines from 2,3-diaryl-indazoles and acetonitrile involving the same electrochemical strategy.

Primary risk assessment of microplastic pollution in spineless cuttlefish () from the North-East Bay of Bengal: A tissue-based analysis.

Microplastic pollution has a significant threat to marine ecosystems, yet its impact on spineless cuttlefish () remains under-researched. This study aims to address this gap by analysing microplastic contamination in from the North-East Bay of Bengal. This species is widely consumed and transported globally as food, thus holding significant health concerns.
