(Wiley, 2011-09-29)
Objectives: Human growth is a complex process that remains insufficiently understood. We aimed to analyze genetic and environmental influences on growth from late childhood to early adulthood.
Methods: Two cohorts of ...
Experiments on a lab scale TES unit using eutectic metal alloy as PCM
(Elsevier, 2015-05)
The behavior of a magnesium and zinc eutectic metal alloy used as thermal energy storage (TES) material is tested in a
laboratory scale TES unit. The TES unit consists of two concentric tubes with the central tube surrounded ...
Aluminum's preferential binding site in proteins: sidechain of amino acids versus backbone interactions
(Elsevier, 2017-11-11)
The interaction of aluminum ion Al(III) with polypeptides is a subject of paramount importance, since it is a central feature to understand its deleterious effects in biological systems. Various drastic effects have been ...
Functional organization of the HIV lipid envelope
(Nature, 2016-09-28)
The chemical composition of the human immunodeficiency virus type 1 (HIV-1) membrane is critical for fusion and entry into target cells, suggesting that preservation of a functional lipid bilayer organization may be required ...
