Posterior segment ocular diseases, such as diabetic retinopathy, age-related macular degeneration, and retinal vein occlusion, are leading causes of vision impairment and blindness worldwide. Effective management of these conditions remains a formidable challenge due to the unique anatomical and physiological barriers of the eye, including the blood-retinal barrier and rapid drug clearance mechanisms. To address these hurdles, nanostructured drug delivery systems are proposed to overcome ocular barriers, target the retina, and enhance permeation while ensuring controlled release.

Pancreatic cancer (PC) is one of the most aggressive malignancies, characterized by an increasing incidence and unfavorable prognosis. Despite recent advances, surgical resection combined with chemotherapy remains the only potentially curative therapeutic option. Therefore, it is of paramount importance to identify novel therapeutic targets and develop effective treatment strategies.

In the background of antioxidation properties of selenium (Se) in plants, the role of nano‑selenium (Se-NPs) was justified in the modulation of Capsicum fruit ripening. In our study, exogenous application of 8 mg L Se-NPs on fruits through 7 days (D) of postharvest storage regulated decay rate, water loss and fruit coat firmness. Se-NPs recovered fruit coat damages with reduction of ion leakage, lipid oxidation, and accumulation of polyamines.

Photoactive complexes of bioessential 3d metals, activable within the phototherapeutic window (650-900 nm), have gained widespread interest due to their therapeutic potential. Herein, we report the synthesis, characterization, and light-enhanced anticancer and antibacterial properties of four new dinuclear Co(II) complexes: [Co(phen)(cat)] (Co-1), [Co(dppz)(cat)] (Co-2), [Co(phen)(esc)] (Co-3), and [Co(dppz)(esc)] (Co-4). In these complexes, phen (1,10-phenanthroline) and dppz (dipyrido[3,2-:2',3'-]phenazine) act as neutral N,N-donor ligands, while cat and esc serve as O,O-donor catecholate ligands derived from catechol (1,2-dihydroxybenzene) and esculetin (6,7-dihydroxy coumarin).
