A review of recent advances biomedical implants and their application

This chapter is focused on some of the most important polymers used for preparing hybrid materials applied in biomedicine. The work is divided into two parts: Non-degradable polymers used for hybrid materials in implants and degradable polymers employed to fabricate biomedical implants and devices. Each part describes the main characteristics of these structures, followed by a list of the most significant polymers and derivatives. This brief introduction could be useful for industry, students, or people interested in the recent advances of biomedical applications where polymers play an important role.

Major Progress

The use CCD detectors has allowed a major progress in abundance derivations for globular cluster stars in the last years. Abundances deduced from high dispersion spectra now correlates well with other abundance indicators. I discuss some problems concerning the derivation of accurate metal abundances for globular clusters using high dispersion spectra from both the old photographic and the most recent CCD data. The discrepant low abundances found by Cohen (1980), from photographic material for M71 giants, are found to be due to the use of too high microturbulences.

Chromatin Structure And Dynamics

In the 30 years since the discovery of the nucleosome, our picture of it has come into sharp focus. The recent high-resolution structures have provided a wealth of insight into the function of the nucleosome, but they are inherently static. Our current knowledge of how nucleosomes can be reconfigured dynamically is at a much earlier stage. Here, recent advances in the understanding of chromatin structure and dynamics are highlighted. The ways in which different modes of nucleosome reconfiguration are likely to influence each other are discussed, and some of the factors likely to regulate the dynamic properties of nucleosomes are considered.
