Long term observations of biomass burning aerosol over Warsaw by means of multiwavelength lidar.

High quality lidar measurements of PollyXT operating at the University of Warsaw in the years 2013-2022 were analyzed to present a comprehensive optical characterization of biomass burning aerosols over Warsaw. The directions of the aerosol inflows were analyzed by dividing advection cases into four types, according to the area of origin: Western Europe, Eastern Europe, the Iberian Peninsula, and North America. It was shown that optical properties of smoke vary in each of these types, and emphasized that aerosol aging processes are important.

Synergic use of in-situ and remote sensing techniques for comprehensive characterization of aerosol optical and microphysical properties.

We report on importance of conducting comprehensive studies of atmospheric aerosol particles, which cannot be done if information from various complementary sensors is unavailable. We present an example for such application and recommend on the types of sensors that should be used in view of the ACTRIS and RI-URBANS new strategies for monitoring at supersites. Although active and passive remote sensing data was not available in continuous mode, we show that synergic use of them with in-situ observations allows for comprehensive study of temporal and height-resolved distribution of aerosol in the lower troposphere and it can be successfully combined to assess biomass burning impact on air quality and optical properties.

Aortic stiffness and valvular calcifications in patients with end-stage renal disease.

Objectives: To evaluate the presence and extent of cardiac calcifications and aortic stiffness in patients with end-stage renal disease (ESRD).

Patients And Methods: The study group consisted of 60 patients with ESRD with a mean age of 51.7 years, treated with peritoneal dialysis.

[Analysis of some risk factors of coronary artery calcification in peritoneal dialysis patients].

Cardiovascular disease (CVD) is a major cause of death in peritoneal dialysed patients (PD-pts). Coronary artery calcification (CAC) is likely to affect the development of CVD. Purpose of our study was to evaluate coronary artery calcification and risk factors of this calcification in PD-pts.

Lipid and apolipoproteins (ApoAI, ApoB, Apo CIII, ApoE) disturbance in hemodialysis (HD) and renal transplant (Tx) patients.

The aim of the study was to evaluate the serum lipid and apolipoprotein profiles among patients after renal transplantation (Tx) and to compare them with the profiles obtained for permanently hemodialysed patients (HD). The investigations were performed at 15 Tx, 40 HD patients and the control group of 40 healthy subjects. There were significantly increased TG, ApoAIII, ApoE, TC/ HDL-C, ApoCIII non B, ApoCIII:B and decreased HDL-C, ApoAI, HDL-C/ApoAI, ApoAI/ApoCIII, ApoB/ApoCIII ratios comparing HD patients to the control group.
