Cultura e desenvolvimento humano sustentável
A cultura é cada vez mais o centro das políticas locais, pela importância que vem revelando no contexto de um paradigma de desenvolvimento humano integral. Para além da atenção que lhe é dirigida graças à sua intima conexão a fatores de índole económica, social e urbana; a sua relevância deve-se essencialmente às relações intrínsecas que mantém com as questões da identidade, da memória, da criatividade, da ciência e do pensamento e conhecimento crítico. Optámos por dividir este livro em três capítulos de modo a permitir uma sequência de leitura, desde as temáticas gerais de grande escala – da União Europeia e da Globalização, até ao cerne do problema que em nosso entendimento urge solucionar nas cidades: a efetiva e definitiva integração da dimensão cultural nas estratégias territoriais de desenvolvimento humano sustentável.N/
CD47 expression is decreased in hematopoietic progenitor cells in patients with myelofibrosis
Myelofibrosis (MF) is characterized by increased circulating hematopoietic progenitor cells (HPCs), abnormal cytokine levels, and the survival advantage of neoplastic progenitors over their normal counterparts, which leads to progressive disappearance of polyclonal hematopoiesis. CD47 is a surface glycoprotein with many functions, such as acting as a phagocytosis inhibitor of the expressing cell, that is increased in normal hematopoietic stem and progenitor cells mobilized into the blood and several human cancer-initiating cells, such as in acute myeloid leukemia. We compared CD47 expression in hematopoietic stem and progenitor cells of patients with MF and controls and found it to be decreased in progenitors of MF. Exposure of control HPCs to the cytokines transforming growth factor β and stromal-derived factor 1, which are important regulators of hematopoietic stem cell cycling and are overexpressed in patients with MF, did not modulate CD47 expression
An Illustrative Case of Neurofibromatosis Type 1 and NF1 Microdeletion
We report on a patient with NF1 microdeletion and clinical manifestations that fulfill the diagnostic criteria for neurofibromatosis type 1 but also presenting features reminiscent of Proteus syndrome
Deletions encompassing 1q41q42.1 and clinical features of autosomal dominant Robinow syndrome

Supplementary Material for: Major Contribution of Genomic Copy Number Variation in Syndromic Congenital Heart Disease: The Use of MLPA as the First Genetic Test
<p>Congenital heart disease (CHD) is the most common congenital disorder
among live births. When associated with extracardiac abnormalities, it
is characterized as a syndromic heart disease (syndromic CHD) and
corresponds to 25% of all liveborn infants with a heart defect. The
etiology in about 65% of the cases still remains unknown, and in about
35% of the patients, it is associated with genetic factors. In the
present study, MLPA and SNP-array techniques were used to investigate a
group of 47 patients with syndromic CHD. In total, 16 defects (34%) were
identified, of which 12 (25.5%) were classified as pathogenic or
probably pathogenic. The most frequent abnormalities were 22q11.2
deletion (22q11.2 deletion syndrome) and 7q11.23 deletion
(Williams-Beuren syndrome). We also show that rarer malformations may be
associated with syndromic CHD, such as 14q32.33 deletion as well as
17q25.3, 15q11.2 (BP1-BP2), 22q13.31, and 12p13.31 (<i>SLC2A3</i>)
duplications. The present study demonstrates that CNVs are important
causal factors and should be studied in patients with syndromic CHD.
Furthermore, the use of MLPA as a first screening test was appropriate,
as this less expensive technology detected 11 of the 12 pathogenic
abnormalities (91.6%).</p
Phenotypic and mutational spectrum of ROR2-related Robinow syndrome
Robinow syndrome is characterized by a triad of craniofacial dysmorphisms, disproportionate-limb short stature, and genital hypoplasia. A significant degree of phenotypic variability seems to correlate with different genes/loci. Disturbances of the noncanonical WNT-pathway have been identified as the main cause of the syndrome. Biallelic variants in ROR2 cause an autosomal recessive form of the syndrome with distinctive skeletal findings. Twenty-two patients with a clinical diagnosis of autosomal recessive Robinow syndrome were screened for variants in ROR2 using multiple molecular approaches. We identified 25 putatively pathogenic ROR2 variants, 16 novel, including single nucleotide variants and exonic deletions. Detailed phenotypic analyses revealed that all subjects presented with a prominent forehead, hypertelorism, short nose, abnormality of the nasal tip, brachydactyly, mesomelic limb shortening, short stature, and genital hypoplasia in male patients. A total of 19 clinical features were present in more than 75% of the subjects, thus pointing to an overall uniformity of the phenotype. Disease-causing variants in ROR2, contribute to a clinically recognizable autosomal recessive trait phenotype with multiple skeletal defects. A comprehensive quantitative clinical evaluation of this cohort delineated the phenotypic spectrum of ROR2-related Robinow syndrome. The identification of exonic deletion variant alleles further supports the contention of a loss-of-function mechanism in the etiology of the syndrome
