ATR maintains chromosomal integrity during postnatal cerebellar neurogenesis and is required for medulloblastoma formation
Microcephaly and medulloblastoma may both result from mutations that compromise genomic stability. We report that ATR, which is mutated in the microcephalic disorder Seckel syndrome, sustains cerebellar growth by maintaining chromosomal integrity during postnatal neurogenesis. Atr deletion in cerebellar granule neuron progenitors (CGNPs) induced proliferation-associated DNA damage, p53 activation, apoptosis and cerebellar hypoplasia in mice. Co-deletions of either p53 or Bax and Bak prevented apoptosis in Atr-deleted CGNPs, but failed to fully rescue cerebellar growth. ATR-deficient CGNPs had impaired cell cycle checkpoint function and continued to proliferate, accumulating chromosomal abnormalities. RNA-Seq demonstrated that the transcriptional response to ATR-deficient proliferation was highly p53 dependent and markedly attenuated by p53 co-deletion. Acute ATR inhibition in vivo by nanoparticle-formulated VE-822 reproduced the developmental disruptions seen with Atr deletion. Genetic deletion of Atr blocked tumorigenesis in medulloblastoma-prone SmoM2 mice. Our data show that p53-driven apoptosis and cell cycle arrest β and, in the absence of p53, non-apoptotic cell death β redundantly limit growth in ATR-deficient progenitors. These mechanisms may be exploited for treatment of CGNP-derived medulloblastoma using ATR inhibition
Amine functionalization of cholecyst-derived extracellular matrix with generation 1 PAMAM dendrimer
This document is the unedited author's version of a Submitted Work that was subsequently accepted for publication in Biomacromolecules, copyright Β© American Chemical Society after peer review. To access the final edited and published work, see http://pubs.acs.org/doi/pdf/10.1021/bm701055k.A method to functionalize cholecyst-derived extracellular matrix (CEM) with free amine groups was established in an attempt to improve its potential for tethering of bioactive molecules. CEM was incorporated with Generation-1 polyamidoamine (G1 PAMAM) dendrimer by using N-(3-dimethylaminopropyl)-Nβ²-ethylcarbodiimide and N-hydroxysuccinimide cross-linking system. The nature of incorporation of PAMAM dendrimer was evaluated using shrink temperature measurements, Fourier transform infrared (FTIR) assessment, ninhydrin assay, and swellability. The effects of PAMAM incorporation on mechanical and degradation properties of CEM were evaluated using a uniaxial mechanical test and collagenase degradation assay, respectively. Ninhydrin assay and FTIR assessment confirmed the presence of increasing free amine groups with increasing quantity of PAMAM in dendrimer-incorporated CEM (DENCEM) scaffolds. The amount of dendrimer used was found to be critical in controlling scaffold degradation, shrink temperature, and free amine content. Cell culture studies showed that fibroblasts seeded on DENCEM maintained their metabolic activity and ability to proliferate in vitro. In addition, fluorescence cell staining and scanning electron microscopy analysis of cell-seeded DENCEM showed preservation of normal fibroblast morphology and phenotype

Carrageenan-based hydrogels for the controlled delivery of PDGF-BB in bone tissue engineering applications
One of the major drawbacks found in most bone tissue engineering approaches developed so far consists in the
lack of strategies to promote vascularisation. Some studies have addressed different issues that may enhance
vascularisation in tissue engineered constructs, most of them involving the use of growth factors (GFs) that are
involved in the restitution of the vascularity in a damaged zone. The use of sustained delivery systems might also
play an important role in the re-establishment of angiogenesis. In this study, !-carrageenan, a naturally occurring
polymer, was used to develop hydrogel beads with the ability to incorporate GFs with the purpose of establishing
an effective angiogenesis mechanism. Some processing parameters were studied and their influence on the final
bead properties was evaluated. Platelet derived growth factor (PDGF-BB) was selected as the angiogenic factor
to incorporate in the developed beads, and the results demonstrate the achievement of an efficient encapsulation
and controlled release profile matching those usually required for the development of a fully functional vascular
network. In general, the obtained results demonstrate the potential of these systems for bone tissue engineering
applications.This work was supported by the European NoE EXPERTISSUES (NMP3-CT-2004-500283), the European STREP HIPPOCRATES (NMP3-CT-2003-505758), and by the Portuguese Foundation for Science and Technology (FCT) through the project PTDC/FIS/68517/2006 and through the V.

Mathematical modeling of an effect of refractory metal nanopowders on the strength of concrete
The quality of concrete and the reliability of its exploitation in structures and structures are largely determined by such characteristic as strength. Additives increasing the strength can significantly improve the quality of concrete. The aim of this work is mathematical modeling of the effect of refractory metal nanopowders on the strength of concrete. Regression equations of the first and second orders are constructed, which adequately find the dependence of the compressive strength of concrete on the input parameters. For presented model the optimal values of the concentrations of refractory metal nanopowders have been calculated
Structural characterization of self-organized mono- and multilayers of partly fluorinated polydialkoxyphosphazenes at the air/water interface
We report studies of the collapse of monolayers of mesomorphic poly[bis-(2,2,3,3,4,4,5,5-octafluo-ropentoxy)phosphazene] and poly[bis-(2,2,3,3,4,4,5,5,6,6,7,7-dodecafluoroheptoxy)phosphazene]. The structure of the films has been examined at different stages of the collapse process by synchrotron grazing incidence X-ray diffraction. Surface pressureβsurface area isotherms show that these films undergo a stepwise collapse with formation of multilayers. Grazing incidence X-ray diffraction reveals only one diffraction peak for the monolayer as well as for multilayers of the two polymers studied, which corresponds to an in-plane interchain spacing d = 15.2Β±0.1Β°Γ
and 17.6Β±0.5Β°Γ
, respectively. The in-plane correlation length ΞΎxy reaches ca. 500 Γ
for PFP-C5 (33 macromolecules) and ca. 400 Γ
for PFP-C7 (23 macromolecules), implying a certain mesoscale order similar to a quasi-long-range one
