The Sapienza University of Rome, officially Sapienza – Università di Roma, also called simply Sapienza formerly known as Università degli studi di Roma "La Sapienza", is a coeducational, autonomous state university in Rome, Italy. It is the largest European university by enrollments and the oldest of Rome's four state universities, founded in 1303. In Italian, sapienza means "wisdom" or "knowledge".Being the biggest Italian University, Sapienza is member of several national and international groups, as: European Spatial Development Planning, Partnership of a European Group of Aeronautics and Space Universities, CINECA, Santander Network, Institutional Network of the Universities from the Capitals of Europe, Mediterranean Universities Union.Sapienza is present in all major international university rankings. It is among the best Italian universities.According to the Academic Ranking of World Universities compiled by the Jiao Tong University of Shanghai, Sapienza is regularly ranked first among Italian universities. Sapienza is positioned within the 101-150 group of universities and among the top 3% of universities in the world.According to webometrics.info La Sapienza is #8th in Europe and #1 in Italy.In 2013, the Center for World University Rankings ranked the Sapienza University of Rome 62nd in the world and the top in Italy in its World University Rankings.According to the American society "U.S News & World Report", La Sapienza is the most prestigious Italian University Wikipedia.

Annual Review of Fluid Mechanics | Year: 2011

We review numerical methods for direct numerical simulation (DNS) and large-eddy simulation (LES) of turbulent compressible flow in the presence of shock waves. Ideal numerical methods should be accurate and free from numerical dissipation in smooth parts of the flow, and at the same time they must robustly capture shock waves without significant Gibbs ringing, which may lead to nonlinear instability. Adapting to these conflicting goals leads to the design of strongly nonlinear numerical schemes that depend on the geometrical properties of the solution. For low-dissipation methods for smooth flows, numerical stability can be based on physical conservation principles for kinetic energy and/or entropy. Shock-capturing requires the addition of artificial dissipation, in more or less explicit form, as a surrogate for physical viscosity, to obtain nonoscillatory transitions. Methods suitable for both smooth and shocked flows are discussed, and the potential for hybridization is highlighted. Examples of the application of advanced algorithms to DNS/LES of turbulent, compressible flows are presented. © 2011 by Annual Reviews. All rights reserved. Source

Bipolar disorders | Year: 2013

Suicidal behavior is a major public health problem worldwide, and its prediction and prevention represent a challenge for everyone, including clinicians. The aim of the present paper is to provide a systematic review of the existing literature on the epidemiology of completed suicides in adult patients with bipolar disorder (BD). We performed a Pubmed/Medline, Scopus, PsycLit, PsycInfo, and Cochrane database search to identify all relevant papers published between 1980 and 2011. A total of 34 articles meeting our inclusion criteria were included in the present review. Several prospective follow-up contributions, many retrospective analyses, and a few psychological autopsy studies and review articles investigated the epidemiology of completed suicides in patients with BD. The main finding of the present review was that the risk for suicide among BD patients was up to 20-30 times greater than that for the general population. Special attention should be given to the characteristics of suicides in patients with BD. Better insight and understanding of suicide and suicidal risk in this very disabling illness should ultimately help clinicians to adequately detect, and thus prevent, suicidal acts in patients with BD. © 2013 John Wiley & Sons A/S.

Annual review of cell and developmental biology | Year: 2014

Two opposing descriptions of so-called mesenchymal stem cells (MSCs) exist at this time. One sees MSCs as the postnatal, self-renewing, and multipotent stem cells for the skeleton. This cell coincides with a specific type of bone marrow perivascular cell. In skeletal physiology, this skeletal stem cell is pivotal to the growth and lifelong turnover of bone and to its native regeneration capacity. In hematopoietic physiology, its role as a key player in maintaining hematopoietic stem cells in their niche and in regulating the hematopoietic microenvironment is emerging. In the alternative description, MSCs are ubiquitous in connective tissues and are defined by in vitro characteristics and by their use in therapy, which rests on their ability to modulate the function of host tissues rather than on stem cell properties. Here, I discuss how the two views developed, conceptually and experimentally, and attempt to clarify the confusion arising from their collision. Source

The revived interest in (hematopoietic) stem cell (HSC) niches has highlighted the role of multiple cellular players found in the bone environment. Initially focused on the role of osteoblasts and sinusoid endothelial cells, the quest for HSC niche cells has recently focused on a unique role for osteoprogenitor cells (skeletal stem cells, mesenchymal stem cells). Strongly validated by observations of HSC dysregulation dictated by the dysregulation of osteoprogenitors, the role of osteoprogenitors in the HSC niche integrates data from different studies into a unified view. As preosteoblastic, periendothelial cells residing at the sinusoid wall, skeletal progenitors reconcile the notions of "osteoblastic" and "sinusoidal" niches with one another. In addition, they bring into focus the cross-regulation of skeletal and hematopoietic physiology as rooted into the interplay of two stem cells (hematopoietic and skeletal) sharing a single niche. As direct regulators of hematopoietic space formation, sinusoid development, and hematopoietic function(s), as well as direct progenitors of positive and negative regulators of HSCs such as osteoblasts and adipocytes, skeletal progenitors have emerged as pivotal organizers of a complex, highly plastic niche. This development seems to represents an evolutionary advance over the deterministic stem cell niches found in archetypal invertebrate systems. © 2011 by The American Society of Hematology. Source
