This article presents a new and facile method for the synthesis of Schiff base compounds with a benzimidazole group using a low-cost and reusable calcium aluminate nanophosphorus catalyst (CaAlO). This approach avoids harmful solvents and reactants, supporting a more environmentally friendly synthesis process. The catalyst maintained its activity and heterogeneity over four cycles with minimal loss of efficiency.

Here, a straightforward design is employed to synthesize a nanocatalyst based on a carbon-activated modified metal-organic framework using the solvothermal method. This work presents a simple and practical approach for producing the activated carbon derived from the Thymus plant (ACT) modified with amine-functionalized isoreticular metal-organic framework-3 (IRMOF-3) to create an ACT@IRMOF-3 core-shell structure. Successful functionalization was confirmed through N adsorption isotherms, FT-IR, FE-SEM, TEM, EDS, elemental mapping, TGA, and XRD analysis.

Dendritic cells (DCs), the primary antigen-presenting cells, have traditionally been identified by CD103 molecules in rats, whereas mouse and human DCs are identified by CD11c molecules. However, this history does not preclude the existence of CD103 DCs in rats. To explore this possibility, we examined MHCII cells in rat spleen and thymus, identifying a novel population of CD103MHCIICD45RCD172a cells.

The condensing reaction of 2-hydroxy-1-naphthaldehyde with quinoxalyl-2-carbohydrazide resulted in synthesizing of a novel derivative of hydrazone quinoxalyl ligand (Hdpq). The bonding behavior between Hdpq and Co(II) ion was investigated in molar ratios of 1: 1 and 2: 1 to produce two different complexes, Codpq and Co(dpq), respectively. Their chemical structure was verified using several spectroscopic approaches.

Dendrobium nobile (D. nobile), a traditional herb known for its immunomodulatory and neuroprotective properties, contains characteristic alkaloids and sesquiterpene glycosides. While alkaloids have been extensively studied, research on sesquiterpene glycosides remains limited.
