The city of the dialectical phenomena. A matter of measure
2020
Istanbul seems to be a suspended city. Split by the strait of the Golden Horn, it boasts the water square included by the estuary on the Bosphorus as its most important public space. Each day a multitude of inhabitants, like nomads, cross those waters professing abiding devotion to a ritual transit. Suspended between homologation and identity, Istanbul finds its figurative theme in a fragment. Its three water bridges apparently show a sense of flaunted modernity in which the attraction between Europe and Asia occurs in a geographic place generating a clash of different identities which at the same time repel and try to captivate one another. Hospitable and dangerous, noble and proletary, gr…
La grande incisione
2020
The Fossa della Garofala is a dramatic depression in the center of the city of Palermo. The essay illustrates a vision of this "piece of landscape within the city" A design workshop has dealt with this issue. The graphic work by the group of students lead by architect Michele Sbacchi is illustrated.
Meta-analysis and imputation refines the association of 15q25 with smoking quantity.
2010
Smoking is a leading global cause of disease and mortality(1). We established the Oxford-GlaxoSmithKline study (Ox-GSK) to perform a genome-wide meta-analysis of SNP association with smoking-related behavioral traits. Our final data set included 41,150 individuals drawn from 20 disease, population and control cohorts. Our analysis confirmed an effect on smoking quantity at a locus on 15q25 (P = 9.45 x 10(-19)) that includes CHRNA5, CHRNA3 and CHRNB4, three genes encoding neuronal nicotinic acetylcholine receptor subunits. We used data from the 1000 Genomes project to investigate the region using imputation, which allowed for analysis of virtually all common SNPs in the region and offered a …
The amphibian globin gene repertoire as revealed by the <i>Xenopus </i>genome
2006
The draft genome sequence of the Western clawed frog <i>Xenopus (Silurana) tropicalis</i> facilitates the identification, expression analysis and phylogenetic classification of the amphibian globin gene repertoire. Frog and mammalian neuroglobin display about 67% protein sequence identity, with the expected predominant expression in frog brain and eye. Frog and mammalian cytoglobins share about 69% of their amino acids, but the frog protein lacks the mammalian-type extension at the C-terminus. Like in mammals, <i>X. tropicalis</i> cytoglobin is expressed in many organs including neural tissue. Neuroglobin and cytoglobin genomic regions are syntenically conserved in a…
The impact of next-generation sequencing technology on preimplantation genetic diagnosis and screening.
2013
Largely because of efforts required to complete the Human Genome Project, DNA sequencing has undergone a steady transformation with still-ongoing developments of high-throughput sequencing machines for which the cost per reaction is falling drastically. Similarly, the fast-changing landscape of reproductive technologies has been improved by genetic approaches. Preimplantation genetic diagnosis and screening were established more than two decades ago for selecting genetically normal embryos to avoid inherited diseases and to give the highest potential to achieve stable pregnancies. Most recent additions to the IVF practices (blastocyst/trophectoderm biopsy, embryo vitrification) and adoption…
Extreme genome reduction in Buchnera spp.: Toward the minimal genome needed for symbiotic life
2002
Buchnera is a mutualistic intracellular symbiont of aphids. Their association began about 200 million years ago, with host and symbiont lineages evolving in parallel since that time. During this coevolutionary process, Buchnera has experienced a dramatic decrease of genome size, retaining only essential genes for its specialized lifestyle. Previous studies reported that genome size in Buchnera spp. is very uniform, suggesting that genome shrinkage occurred early in evolution, and that modern lineages retain the genome size of a common ancestor. Our physical mapping of Buchnera genomes obtained from five aphid lineages shows that the genome size is not conserved among them, but has been red…
Progress in Arabidopsis genome sequencing and functional genomics
2000
Arabidopsis thaliana has a relatively small genome of approximately 130 Mb containing about 10% repetitive DNA. Genome sequencing studies reveal a gene-rich genome, predicted to contain approximately 25 000 genes spaced on average every 4.5 kb. Between 10 to 20% of the predicted genes occur as clusters of related genes, indicating that local sequence duplication and subsequent divergence generates a significant proportion of gene families. In addition to gene families, repetitive sequences comprise individual and small clusters of two to three retroelements and other classes of smaller repeats. The clustering of highly repetitive elements is a striking feature of the A. thaliana genome emer…
TMPRSS4 is a type II transmembrane serine protease involved in cancer and viral infections.
2012
Abstract Proteolytic enzymes are involved in almost all biological processes reflecting their importance in health and disease. The human genome contains nearly 600 protease-encoding genes forming more than 2% of the total human proteome. The serine proteases, with about 180 members, built the oldest and second largest family of human proteases. Ten years ago, a novel serine protease family named the type II transmembrane family (TTSP) was identified. This minireview summarizes the up-to-date knowledge about the still growing TTSPs, particularly focusing on the pathophysiological functions of the family member type II transmembrane serine protease (TMPRSS) 4. Recent studies provided importa…
HLA typing from RNA-Seq sequence reads.
2012
We present a method, seq2HLA, for obtaining an individual's human leukocyte antigen (HLA) class I and II type and expression using standard next generation sequencing RNA-Seq data. RNA-Seq reads are mapped against a reference database of HLA alleles, and HLA type, confidence score and locus-specific expression level are determined. We successfully applied seq2HLA to 50 individuals included in the HapMap project, yielding 100% specificity and 94% sensitivity at a P-value of 0.1 for two-digit HLA types. We determined HLA type and expression for previously un-typed Illumina Body Map tissues and a cohort of Korean patients with lung cancer. Because the algorithm uses standard RNA-Seq reads and …
Genomic structure and paralogous regions of the inversion breakpoint occurring between human chromosome 3p12.3 and orangutan chromosome 2.
2003
Intrachromosomal duplications play a significant role in human genome pathology and evolution. To better understand the molecular basis of evolutionary chromosome rearrangements, we performed molecular cytogenetic and sequence analyses of the breakpoint region that distinguishes human chromosome 3p12.3 and orangutan chromosome 2. FISH with region-specific BAC clones demonstrated that the breakpoint-flanking sequences are duplicated intrachromosomally on orangutan 2 and human 3q21 as well as at many pericentromeric and subtelomeric sites throughout the genomes. Breakage and rearrangement of the human 3p12.3-homologous region in the orangutan lineage were associated with a partial loss of dup…
