Relativistic Nucleus-Nucleus Collisions and the QCD Matter Phase Diagram
This review will be concerned with our knowledge of extended matter under the
governance of strong interaction, in short: QCD matter. Strictly speaking, the
hadrons are representing the first layer of extended QCD architecture. In fact
we encounter the characteristic phenomena of confinement as distances grow to
the scale of 1 fm (i.e. hadron size): loss of the chiral symmetry property of
the elementary QCD Lagrangian via non-perturbative generation of "massive"
quark and gluon condensates, that replace the bare QCD vacuum. However, given
such first experiences of transition from short range perturbative QCD
phenomena (jet physics etc.), toward extended, non perturbative QCD hadron
structure, we shall proceed here to systems with dimensions far exceeding the
force range: matter in the interior of heavy nuclei, or in neutron stars, and
primordial matter in the cosmological era from electro-weak decoupling (10^-12
s) to hadron formation (0.5 10^-5 s). This primordial matter, prior to
hadronization, should be deconfined in its QCD sector, forming a plasma (i.e.
color conducting) state of quarks and gluons: the Quark Gluon Plasma (QGP).Comment: 146 pages, 83 figure
Identification of a novel susceptibility locus at 13q34 and refinement of the 20p12.2 region as a multi-signal locus associated with bladder cancer risk in individuals of European ancestry
Candidate gene and genome-wide association studies (GWAS) have identified 15 independent genomic regions associated with bladder cancer risk. In search for additional susceptibility variants, we followed up on four promising single-nucleotide polymorphisms (SNPs) that had not achieved genome-wide significance in 6911 cases and 11 814 controls (rs6104690, rs4510656, rs5003154 and rs4907479, P < 1 × 10−6), using additional data from existing GWAS datasets and targeted genotyping for studies that did not have GWAS data. In a combined analysis, which included data on up to 15 058 cases and 286 270 controls, two SNPs achieved genome-wide statistical significance: rs6104690 in a gene desert at 20p12.2 (P = 2.19 × 10−11) and rs4907479 within the MCF2L gene at 13q34 (P = 3.3 × 10−10). Imputation and fine-mapping analyses were performed in these two regions for a subset of 5551 bladder cancer cases and 10 242 controls. Analyses at the 13q34 region suggest a single signal marked by rs4907479. In contrast, we detected two signals in the 20p12.2 region—the first signal is marked by rs6104690, and the second signal is marked by two moderately correlated SNPs (r2 = 0.53), rs6108803 and the previously reported rs62185668. The second 20p12.2 signal is more strongly associated with the risk of muscle-invasive (T2-T4 stage) compared with non-muscle-invasive (Ta, T1 stage) bladder cancer (case–case P ≤ 0.02 for both rs62185668 and rs6108803). Functional analyses are needed to explore the biological mechanisms underlying these novel genetic associations with risk for bladder cancer

The management of moderate-to-severe chronic plaque psoriasis
Recent approval and marketization of novel treatments have widened the range of therapeutic opportunities for moderate-to-severe psoriasis. In the next years, this panorama will be further enlarged as many other agents, both oral small molecules and biologics, have passed phase III and are expected to be approved, and subsequently marketed, shortly. In spite of this array of therapeutic possibilities, there is still an unmet need for an appropriate treatment in a large number of cases. This review was aimed to describe general principles regarding the therapeutic approach to moderate-severe plaque psoriasis, providing an updated overview of the therapeutic armamentarium that is specifically available in Italy, drug prescriptibility, and some peculiar limitations for reimbursement defined by our National Health Care System
Maternal Age at Delivery Is Associated with an Epigenetic Signature in Both Newborns and Adults.
Offspring of older mothers are at increased risk of adverse birth outcomes, childhood cancers, type 1 diabetes, and neurodevelopmental disorders. The underlying biologic mechanisms for most of these associations remain obscure. One possibility is that maternal aging may produce lasting changes in the epigenetic features of a child's DNA. To test this, we explored the association of mothers' age at pregnancy with methylation in her offspring, using blood samples from 890 Norwegian newborns and measuring DNA methylation at more than 450,000 CpG sites across the genome. We examined replication of a maternal-age finding in an independent group of 1062 Norwegian newborns, and then in 200 US middle-aged women. Older maternal age was significantly associated with reduced methylation at four adjacent CpGs near the 2nd exon of KLHL35 in newborns (p-values ranging from 3x10-6 to 8x10-7). These associations were replicated in the independent set of newborns, and replicated again in women 40 to 60 years after their birth. This study provides the first example of parental age permanently affecting the epigenetic profile of offspring. While the specific functions of the affected gene are unknown, this finding opens the possibility that a mother's age at pregnancy could affect her child's health through epigenetic mechanisms
