The invention concerns a method of manufacturing objects by selective laser melting (SLM) in which between the forming of subsequent layers of the object a plastic deformation and residual stresses are induced into the solidified material of at least one of said layers to improve the mechanical properties and the fatigue life of the object. This step is carried out with a laser, as a LSP or WLSP step. The invention also concerns a system to carry out the method.

The invention relates to a scaffold material comprising a carrier and embedded microbeads for use in tissue engineering applications such as soft tissues therapeutic treatment. The scaffold provides a short-term bulking effect coupled with a long-term functional activity. Both the carrier and the microbeads are substantially composed of natural or extracellular matrix-derived polymers, and the beads can comprise homogeneously distributed active agents, providing a regulated agent release along time. An aspect of the invention relates to a method for producing the microbeads of the invention by using an expressly designed microfluidic chip.

The centriole is an evolutionarily conserved macromolecular structure that is crucial for the formation of flagella, cilia and centrosomes. The ultrastructure of the centriole was first characterized decades ago with the advent of electron microscopy, revealing a striking ninefold radial arrangement of microtubules. However, it is only recently that the molecular mechanisms governing centriole assembly have begun to emerge, including the elucidation of the crucial role of spindle assembly abnormal 6 (SAS-6) proteins in imparting the ninefold symmetry. These advances have brought the field to an exciting era in which architecture meets function. © 2012 Macmillan Publishers Limited. All rights reserved.

Understanding the biology of the breast and how ovarian hormones impinge on it is key to rational new approaches in breast cancer prevention and therapy. Because of the success of selective oestrogen receptor modulators (SERMs), such as tamoxifen, and aromatase inhibitors in breast cancer treatment, oestrogens have long received the most attention. Early progesterone receptor (PR) antagonists, however, were dismissed because of severe side effects, but awareness is now increasing that progesterone is an important hormone in breast cancer. Oestrogen receptor-α (ERα) signalling and PR signalling have distinct roles in normal mammary gland biology in mice; both ERα and PR delegate many of their biological functions to distinct paracrine mediators. If the findings in the mouse model translate to humans, new preventive and therapeutic perspectives might open up. © 2013 Macmillan Publishers Limited. All rights reserved.
