This manuscript explores the post-synthetic modification (PSM) of amine-functionalized porous coordination cages, specifically focusing on the formation of imine bonds through reactions with aldehydes. Targeting various cage topologies, including zirconium-, magnesium-, and molybdenum-based structures, we demonstrate the tunability of cage solubility and porosity through selective functionalization where the proximity of amine groups on the parent cage impacts the extent of modification. The work highlights the reversible nature of imine formation, offering potential applications in solubility switching and mixed-metal solid synthesis.

Previously, we knew them to be moderately venomous snakes, primarily causing local envenomation. However, recent reports have indicated severe systemic envenomation incidents, which include hemostatic dysfunction, microangiopathic hemolysis, kidney injury, myocardial toxicity, and even death.

Although humanitarian missions were quick to supply materials, there was a lack of scientific evidence to predict the required intraocular lens power for patients with cataracts. This study aimed to assess the average lens power among patients from Trincomalee district, Sri Lanka, based on sex and age groups.

With the realization of the failures and limitations of current vector control strategies, the authorities are moving towards simple, low- cost, and eco-friendly vector management methods. Thus, the present study was devised to evaluate the potential densities of mosquito natural enemies in natural water habitats in Galle district, Sri Lanka, and to investigate the feeding efficacy of prominent mosquito natural enemies on main dengue vectors (Aedes sp.
