Two features of macrophages make them attractive for targeted transport of drugs: they efficiently take up a broad spectrum of nanoparticles (NPs) and, by sensing cytokine gradients, they are attracted to the sites of infection and inflammation. To expand the potential of macrophages as drug carriers, we investigated whether macrophages could be simultaneously coloaded with different types of nanoparticles, thus equipping individual cells with different functionalities. We used superparamagnetic iron oxide NPs (SPIONs), which produce apoptosis-inducing hyperthermia when exposed to an alternating magnetic field (AMF), and co-loaded them on macrophages together with drug-containing NPs (inorganic-organic nanoparticles (IOH-NPs) or mesoporous silica NPs (MSNs)).

Integrin antagonist complex (IAC), a novel αvβ3 integrin antagonist peptidomimetic, has emerged as a promising agent for molecular imaging of tumor angiogenesis. This study evaluates the biodistribution and clinical efficacy of [Ga]Ga-DOTAGA-IAC PET/CT in detecting radioiodine-refractory differentiated thyroid carcinoma (RAIR-DTC), comparing its diagnostic performance with [F]F-FDG PET/CT. In this prospective pilot study, RAIR-DTC patients underwent whole-body imaging with [F] F-FDG PET/CT, followed by [Ga]Ga-DOTAGA-IAC PET/CT.

Drought stress remains a serious concern in L. var , cultivar Satabdi (IET4786) production, particularly during the earliest growth phases, ultimately affecting yield due to the recent trend of delayed rain arrival in West Bengal, India. This study aimed to develop a cost-effective strategy to improve the drought tolerance capacity of rice seedlings by priming the seeds with flavonoid-enriched extract (FEE) of French marigold () petals to withstand the initial drought milieu.

Imidazo based heterocyclic derivatives are considered as privileged scaffolds due to their presence in various pharmacologically active compounds and in marketed formulations. The present study reports toxicological evaluation of three imidazo based heterocyclic derivatives which are currently being investigated for their potential anticancer activity. Compounds IG-01-007, IG-01-008, and IG-01-009 were assessed for cytotoxicity, hemolysis, and DNA fragmentation activity.
