Magnesium oxide-water compounds at megabar pressure and implications on planetary interiors.

Magnesium Oxide (MgO) and water (HO) are abundant in the interior of planets. Their properties, and in particular their interaction, significantly affect the planet interior structure and thermal evolution. Here, using crystal structure predictions and ab initio molecular dynamics simulations, we find that MgO and HO can react again at ultrahigh pressure, although Mg(OH) decomposes at low pressure.

Exploring the link between star and planet formation with Ariel.

The goal of the Ariel space mission is to observe a large and diversified population of transiting planets around a range of host star types to collect information on their atmospheric composition. The planetary bulk and atmospheric compositions bear the marks of the way the planets formed: Ariel's observations will therefore provide an unprecedented wealth of data to advance our understanding of planet formation in our Galaxy. A number of environmental and evolutionary factors, however, can affect the final atmospheric composition.

The impact of left ventricular ejection fraction on heart failure patients with pulmonary hypertension.

Background: The most common cause of pulmonary hypertension (PH) in developed countries is left heart disease (LHD, group 2 PH). The development of PH in heart failure (HF) patients is indicative of worse outcomes.

Objective: The aim of this study was to evaluate the long term outcomes of HF patients with PH in a national long-term registry.

The Management and Outcome of Hospitalized and Ambulatory Israeli Heart Failure Patients Compared to European Heart Failure Patients: Results from the ESC Heart Failure Long-Term Registry.

Background: The treatment of patients hospitalized with heart failure (HHF) and ambulatory chronic heart failure (CHF) differs in various countries.

Objectives: To evaluate the management and outcomes of patients with HFF and CHF in Israel compared to those in other European countries who were included in the ESC-HF Long-Term Registry.

Methods: From May 2011 to April 2013, heart failure patients - 467 Israelis and 11,973 from other countries - were evaluated.

Primary lymphoma of the heart: three-dimensional reconstruction.

Primary cardiac lymphoma is defined as a lymphoma of the heart and pericardium with little or no extracardiac or local involvement such as mediastinal lymph nodes or pleural effusion. Most cases are diagnosed only post mortem (1). If this disease could be diagnosed earlier, therapy with chlorpropamide, doxorubicin, vincristine and prednisone (CHOP) could bring about a remission (2,3,4).
