Dietary Zinc Is Associated with Cardiac Function in the Older Adult Population.

The elderly is a group at particularly high cardiovascular risk. The coexistence of chronic diseases and use of multiple medications creates the need to look for non-pharmacological agents to improve cardiovascular health in that population. In view of reports on the potential role of zinc in enhancing pathways of myocardial tissue repair, the aim of this study was to evaluate the association between dietary zinc intake and cardiac structure and function in individuals of advanced age.

A simple solution to the problem of self-assembling cubic diamond crystals.

The self-assembly of colloidal diamond (CD) crystals is considered as one of the most coveted goals of nanotechnology, both from the technological and fundamental points of view. For applications, colloidal diamond is a photonic crystal which can open new possibilities of manipulating light for information processing. From a fundamental point of view, its unique symmetry exacerbates a series of problems that are commonly faced during the self-assembly of target structures, such as the presence of kinetic traps and the formation of crystalline defects and alternative structures (polymorphs).

SAT-assembly: a new approach for designing self-assembling systems.

We propose a general framework for solving inverse self-assembly problems, i.e. designing interactions between elementary units such that they assemble spontaneously into a predetermined structure.

Comparison of Nutrition Risk Screening 2002 and Subjective Global Assessment Form as Short Nutrition Assessment Tools in Older Hospitalized Adults.

The aim of the present study was to compare two widely recommended short nutrition assessment tools-Nutrition Risk Screening 2002 (NRS-2002) and Subjective Global Assessment Form (SGA)-with other Comprehensive Geriatric Assessment (CGA) measurements. The study included 622 consecutively hospitalized older subjects, aged 81.7 ± 7.

Designing Patchy Interactions to Self-Assemble Arbitrary Structures.

One of the fundamental goals of nanotechnology is to exploit selective and directional interactions between molecules to design particles that self-assemble into desired structures, from capsids, to nanoclusters, to fully formed crystals with target properties (e.g., optical, mechanical, etc.
