The nature of an ultra-faint galaxy in the cosmic dark ages seen with JWST.

In the first billion years after the Big Bang, sources of ultraviolet (UV) photons are believed to have ionized intergalactic hydrogen, rendering the Universe transparent to UV radiation. Galaxies brighter than the characteristic luminosity L* (refs. ) do not provide enough ionizing photons to drive this cosmic reionization.

[The Regional Registry of Sudden Cardiac Death of Friuli Venezia Giulia. Protocols, best practices and results of a multidisciplinary project].

With the regional law n. 26 of December 30, 2020, the Friuli Venezia Giulia Region wanted to promote the establishment of the Regional Register of Sudden Cardiac Death, with the aim of favoring the study of all those deaths that occurred suddenly and unexpectedly under the age of 50 years in which it is not possible to trace the cause of death with certainty. Such dramatic events, difficult to quantify considering the complexity of data collection, are often accepted with resignation without any further investigation of the possible causes.

An excess of small-scale gravitational lenses observed in galaxy clusters.

Cold dark matter (CDM) constitutes most of the matter in the Universe. The interplay between dark and luminous matter in dense cosmic environments, such as galaxy clusters, is studied theoretically using cosmological simulations. Observations of gravitational lensing are used to characterize the properties of substructures-the small-scale distribution of dark matter-in clusters.

[Cardiological counseling and perioperative management of heart disease patients. Protocol of the University of Trieste - Year 2019].

The management of patients with heart disease or suspected heart disease, who are hospitalized and/or who should undergo surgery or an invasive procedure, is very complex for the comorbidities often present, the multiple therapies taken and the frequent presence of advanced cardiac devices.The purpose of this document is to provide indications and standardize the behavior of different clinicians in the management of heart disease patients or those with suspected heart disease in order (i) to manage acute cardiac conditions with appropriate timing and accuracy, and (ii) to define the cardiovascular risk in the individual patient with appropriate timing and indications, allowing patients to face any surgery or invasive procedure with the lowest risk correlated to his heart disease.

A new amido-phosphine of dichloroacetic acid as an active ligand for metals of pharmaceutical interest. Synthesis, characterization and tests of antiproliferative and pro-apoptotic activity.

We herein describe the synthesis and characterization of the new amido-phosphinic ligand 3,7‑bis(dichloroacetyl)‑1,3,7‑triaza‑5‑phosphabicyclo[3.3.1]nonane (DCP), a derivative of dichloroacetic acid (DCA), whose ability to reverse the suppressed mitochondrial apoptosis in cancer cells is known.
