Article Synopsis
- The study investigates heart failure (HF) markers in patients with professional chronic obstructive pulmonary disease (PCOPD), a specific type of COPD, and the challenges in diagnosing HF in these patients.
- A total of 345 patients were included, with 115 each in three groups: those with PCOPD, smokers with COPD, and healthy controls, matched for age, sex, and COPD duration.
- Key findings revealed that HF in PCOPD patients often involves biventricular damage, preserved heart function, and increased hospitalization rates, with several identified markers like high pulmonary artery pressure and specific protein levels indicating HF at a diagnostic sensitivity of
Aim: To establish the efficacy of 13-valent pneumococcal conjugate vaccine (PCV13) for healthcare workers protection from occupational acquired infection and impact of healthcare staff vaccination on the risk of transmission to patients.
Materials And Methods: Healthcare personnel (n=157 of whom 105 critical care department staff) and 1770 patients of that critical care department observed. Healthcare workers received PCV13.
Article Synopsis
- This article explores the stability of fullerene colloids in methyl alcohol, focusing on how electrolytes affect coagulation.
- The experiments involved creating alcosols with a fullerene concentration of 4 × 10 M and examining their properties, showing aggregates of about 300 nm with a negative electrokinetic potential.
- Findings indicate that while 1:1 electrolytes like NaClO have negatively charged colloidal species, certain metal ions can cause a temporary positive charge, demonstrating the complex interactions in these systems.
Towards better understanding of C60 organosols.

It is of common knowledge that fullerenes form colloids in polar solvents. However, the coagulation via electrolytes and the origin of the negative charge of species are still unexplored. Using a 'radical scavenger' and electrospray ionization spectroscopy (ESI), we proved the formation of ion-radical C60˙(-) and its (probable) transformation into C60(2-) or (C60)2(2-).
