Article Abstract
The coordination chemistry of a series of pro-ligands ([L¹]-[L⁶]) with cobalt and zinc derivatives has been studied. All complexes have been characterized by multinuclear NMR, elemental analysis, and by single-crystal X-ray diffraction studies. Polymerization of rac-lactide takes place at 130 °C in the presence of cobalt and zinc complexes to yield polymers under solvent free conditions with controlled molecular masses and narrow polydispersities.

Background And Aim: The global demand for efficient poultry production necessitates alternatives to antibiotic growth promoters. This study aimed to evaluate the effects of a novel four-component organic-mineral feed additive (OMFA), comprising lactulose, arginine, ultrafine silicon dioxide particles, and succinic acid, and a three-component variant (without lactulose) on growth performance, nutrient digestibility, elemental tissue composition, and the cecal microbiota of Arbor Acres broiler chickens.
Materials And Methods: One hundred and five one-day-old broiler chicks were randomly allocated into three groups: Control, Group I (four-component OMFA), and Group II (three-component OMFA).

Harnessing the significant buildup of lactic acid (LA) within the tumor microenvironment (TME) for metabolic manipulation presents a promising avenue for cancer treatment. Nevertheless, single-agent therapies often fail to address the complex and varying needs of TME heterogeneity, posing a substantial scientific hurdle in oncology. In this context, we employ asymmetric mesoporous silica nanoparticles (AMS NPs) as delivery vehicles, simultaneously loading them with zinc‑cobalt‑manganese ferrite nanoparticles (ZCMF NPs), lactate oxidase (LOX), and doxorubicin (DOX).

BackgroundGiven the increasing global prevalence of Parkinson's disease (PD) and its complex etiopathogenesis, understanding the role of environmental factors is crucial. Prior investigations suggested a potential link between metal exposure and PD, yet conflicting results emerged.ObjectiveTo identify differences in metal concentrations in whole blood and cerebrospinal fluid (CSF) in PD patients compared to controls.

Conventional cobalt spinel oxides, widely employed in advanced oxidation processes, suffer from limited catalytic activity due to competitive overlap of O 2p orbitals between tetrahedral (Co) and octahedral cobalt (Co). Furthermore, their narrow pH activity window near neutrality severely restricts environmental applicability. To address these limits, the theories of covalency competition and microenvironment modulation are introduced to simulate the catalytic process and propose optimization strategies.
