Detection and quantification limits were lower than 6.6 and 22.0 μg/kg for the studied analytes, respectively.The synthesis of stereoregular telechelic polypropylene (PP) and their use to access triblock amphiphilic copolymers with the PP block located in the center is described. The strategy consists of selectively copolymerizing propylene and a di-functional co-monomer (1,3-diisopropenylbenzene) to yield a α,ω-substituted polypropylene. Initiation of the copolymerization favors insertion of DIB over propylene; propagation steps favor insertion of propylene. Termination via a chain-transfer reaction yields the terminal unsaturation of the polymer. The telechelic polypropylene is then converted into α,ω-hydroxyl-terminated polypropylene and used as a macroinitiator for the synthesis of triblock copolymers. Water-soluble amphiphilic triblock polymers are also synthesized. The use of catalytic reactions simultaneously provides the stereocontrol of the polypropylene and high productivity (multiple chains of block copolymer per metal center). Low-grade albuminuria, as an early marker of endothelial dysfunction and kidney damage, has been recognized as a risk factor for metabolic disorders. Epidemiological studies manifesting the association of low-grade albuminuria with the risk of incident NAFLD and fibrosis were not available. We aimed to investigate the association of low-grade albuminuria with incident NAFLD and fibrosis by glycaemia status. A prospective population-based study was performed in 3308 participants without NAFLD at recruitment. Baseline urinary albumin excretion was obtained by a first-voided early morning spot urine sample. At follow-up visit, incident NAFLD was diagnosed by hepatic ultrasound after excluding
