In this study, the effectiveness of the synthesized Schiff's base, N,N-bis(acetonylacetone)-p-aminoacetophenone-o-phenylene diamine, in detecting environmental pollutants, including mercury (Hg(II)) and lead (Pb(II)), using UV/VIS spectrophotometry, was evaluated. Acetonitrile was chosen as the optimal solvent. Emphasis was placed on reaction conditions, including micelle effects, to enhance results. The study underscores the importance of Schiff's base compounds for environmental monitoring, particularly in detecting mercury and lead pollution.

Abstract During a phase I evaluation of diglycoaldehyde (INOX), an intravenous chemotherapeutic agent used to treat children with malignancies, all of eight patients tested developed a positive direct antiglobulin test (DAT) in vivo. The DAT became positive within one to seven days after the first administration of the drug and remained positive for up to 12 days following the last dose. The indirect antiglobulin tests were negative. None of the patients showed clinical or laboratory evidence of hemolysis at the time the DAT became positive or during follow-up.

This manuscript presents a novel instant additive for elastomeric polymers, specifically focusing on the modification of synthesized mesoporous silica using carbonyl telechelic natural rubber (CTNR). The surface of mesoporous silica particles was modified using a two-step approach. In the first step, a strategy involving the grafting of 3-aminopropyltriethoxysilane (APTES) onto the silica particles was employed. Subsequently, in the second step, a Schiff's base reaction was carried out between the aldehyde functional group of CTNR and the amines on the modified silica surface. The grafting per

Colleters are secretory structures of taxonomic relevance that are characterized by the production of a mucilaginous substance in the shoot apices and the development of organs that act against dehydration, herbivores, and pathogens. However, no studies have investigated the senescence and programmed cell death processes of colleters. The goal of this study was to describe the structure of Alseis pickelii Pilger et Shmale (Cinchonoideae) colleters and to characterize the process of senescence.
