Summary: Catalyst based on palladium nanoparticles and poly(propyleneimine) (PPI) dendrimers immobilized on mesoporous phenol-formaldehyde support was synthesized. Catalytic characteristics were evaluated in the hydrogenation of 1-octyne, 4-octyne, and 1-hexyne. High selectivity for alkenes (up to 99%) was achieved. Synthesized hybrid catalyst can be recycled without a loss of activity and additional regeneration.

The cost for treatment of DFU by a multidisciplinary team in the federal medical institution was substantially higher than basic medical insurance tariff for this disease. Because revascularization procedures appeared to be the main cost driver, our results stress the need for careful implementation of this type of treatment for patients with DFU.
