Five-year follow-up of left ventricular diastolic function in systemic sclerosis patients: determinants of mortality and disease progression.

Objectives: In systemic sclerosis (SSc), left ventricular diastolic dysfunction reflects primary myocardial involvement of the disease. We aimed to assess the abnormalities of the diastolic function, analyze the characteristics of the disease progression, and investigate the prognostic value of diastolic dysfunction in SSc patients.

Patients And Methods: A total of 34 SSc patients (57 ± 12 years, 31 female) were involved in the study.

Adsorption of Cs on titanium ferrocyanide and transformation of the sorbent to lithium titanate: a new method for long term immobilization of Cs.

Dynamic adsorption of radiocesium on titanium ferrocyanide grains from reactor coolant simulating solution containing salts at moderate concentrations has been investigated. Effective decontamination of the neutral solutions has been achieved, in the amounts of a more than 20 thousand bed volumes. After adsorption the titanium ferrocyanide was transferred to titanates and calcined at 900 °C.

Impact of cardiac involvement on the risk of mortality among patients with systemic sclerosis: a 5-year follow-up of a single-center cohort.

Cardiac involvement is among the leading causes of mortality in patients with systemic sclerosis (SSc). Previously, we demonstrated in a single-center, cross-sectional study the frequent coexistence of different forms of cardiac involvement in systemic sclerosis including pulmonary arterial hypertension (PAH), coronary artery disease (CAD), and microvascular dysfunction (MVD). The aim of the present study was to investigate the prognostic significance of cardiac involvement.

Separation of fission produced Ru from simulated high level nuclear wastes for production of brachytherapy sources.

An effective and simple process for the isolation of Ru from high-level liquid wastes was developed. Radioactive ruthenium was oxidized by HIO in HNO solution and was extracted to CCl phase in the form of RuO. In order to obtain ruthenium in the suitable form for production of brachytherapy sources, RuO in organic phase was reduced and re-extracted to aqueous phase.

Search of ligands suitable for Pb/Bi in vivo generators.

The short half-life of Bi and Bi limits the application of these radionuclides in α radionuclide therapy. The labeling of biomolecules with Pb (mother nuclide of Bi) instead of Bi or Bi has the advantage of obtaining a conjugate with a half-life of 10.6 h, compared with of 60 min for Bi or 46 min for Bi.
