This work describes the synthesis and characterization of three novel complexes derived from N-benzyl-ethylenediamine and oxalate. Precursor compounds were synthesized by reacting N-benzyl-ethylenediamine with K(2)PtCl(4). Subsequent substitution of chlorides by oxalate led to the final products. Elemental analysis and the infrared, (1)H, (13)C, and (195)Pt NMR spectra of these complexes were provided. The cytotoxic activities were investigated against human non-small cell lung carcinoma (A(549)), mouse non-metastatic cell skin melanoma (B16-F1), mouse metastatic cell skin melanoma (B16-F10), human cell breast adenocarcinoma (MDA-MB-231) and normal cell lines such as baby hamster cell kidney (BHK-21), hamster cell ovary (CHO) and compared to cisplatin and carboplatin under the same experimental conditions. The presence of oxalate as a leaving group conferred an interesting cytotoxicity profile to the complexes in the tested cell lines.

The challenge of "false positive" signals significantly complicates tumor localization and surgical resection, which are pivotal for successful tumor surgeries. Therefore, the development of a method for preoperative tumor localization and intraoperative margin determination holds considerable promise for improving surgical outcomes. In this study, a zero-crosstalk ratiometric tumor-targeting near-infrared (NIR) fluorescent probe was developed for precise cancer diagnosis and intraoperative navigation via NIR fluorescence imaging.

Construction materials are significantly exposed to ecological hazards due to the presence of hazardous chemical constituents found in industrial and agricultural solid wastes. This study aims to investigate the use of sawdust particles (SDPs) and sawdust wastewater (SDW) in alkali-activated composites (AACs) made from a mixture of different silicon-aluminum-based solid wastes (slag powder-SP, red mud-RM, fly ash-FA, and carbide slag-CS). The study examines the impact of SDP content, treated duration of SDPs, and SDW content on both fresh and hardened properties of the AACs, including electrical conductivity, fluidity, density, flexural and compressive strengths, and drying shrinkage.

Lysosomal pH dysregulation is a critical element of the pathophysiology of neurodegenerative diseases, cancers, and lysosomal storage disorders (LSDs). To study the role of lysosomes in pathophysiology, probes to analyze lysosomal size, positioning, and pH are indispensable tools. Here, we developed and characterized a ratiometric genetically encoded lysosomal pH probe, RpH-ILV, targeted to a subpopulation of lysosomal intraluminal vesicles.

Cross-feeding involves microbes consuming exudates of other surrounding microbes, mediating elemental cycling. Characterizing the diversity of cross-feeding pathways in ocean microbes illuminates evolutionary forces driving self-organization of ocean ecosystems. Here, we uncover a purine and pyrimidine cross-feeding network in globally abundant groups.

Particle elasticity has widely been established to substantially influence immune cell clearance and circulation time of vascular-targeted carriers (VTCs). However, prior studies have primarily investigated interactions with macrophages, monocytic cell lines, and in vivo murine models. Interactions between particles and human neutrophils remain largely unexplored, although they represent a critical aspect of VTC performance.
