The aim of this paper is to present a distribution of new localities of Doronicum austriacum Jacq. which have been noticed in the upper section of Kamienna river valley (Wyżyna Małopolska Upland), to describe number of individuals of populations and to characterize habitats of this species in study area. In the Kamienna river valley five new localities of D. austriacum have been found. On most of the sites the species grows in brushwood of marshy meadow. All the new localities are placed in one ATPOL square (10 × 10 km) - EE 45 and delimit the north range of the species in Poland.

There are many sources of heavy metals in the environment. They can get there from the atmosphere as a result of intensive rain or snowfall, or they can be eroded out of the bedrock or soil. Larger amounts, often exceeding permitted concentrations, are most frequently due to emissions/discharges from industrial areas. The great variety of sources and physico-chemical conditionsmeans that an element can occur inmany different forms. That is why any assessment of the degree of contamination of the environment should be carried out not only from the point of view of the total amount of a metal found in environmental samples; it is also very important to know the contents of stable species of metals, constituting a potential reserve in the biocirculation. Moreover, the forms of occurrence of aluminum determine its toxicity or the synergistic relationships it enters into with other substances, which in turn determine its uptake and absorption by living organisms. © Taylor and Francis Group, LLC.

Background: Measurement of natriuretic peptide's (NP) release in response to hemodynamic stress may be complementary to its baseline assessment in individuals. Atrial natriuretic peptide (ANP) and B-type natriuretic peptide (BNP) increase in patients with atrial fibrillation (AF) and decrease after successful cardioversion, suggesting that AF may stimulate secretion of NPs. However, there are conflicting data on the predictive value of NPs on the cardioversion outcome. Objectives: The purpose of this study was to investigate whether baseline and exercise-induced NP plasma levels can be useful in predicting successful cardioversion of persistent AF and maintenance of sinus rhythm during 6-month follow-up. Methods: A prospective study enrolled 77 consecutive subjects with persistent AF with normal left ventricular function, referred for elective cardioversion. Patients underwent a modified Bruce protocol treadmill exercise test 24 hours before cardioversion. Blood samples for ANP and BNP analyses were obtained at rest and 5 minutes after exercise peak. Results: The group of successful cardioversion and stable sinus rhythm presented higher exercise ANP (110.6 ± 41.2 pg/mL vs 43.8 ± 36.1; pg/mL, P < 0.0001) and lower BNP increase (5.2 ± 5.2 pg/mL vs 40.5 ± 34.2 pg/mL, P < 0.0001) than the group of unsuccessful cardioversion or AF recurrence. Using an optimized cutoff level of ≤12% of relative exercise-induced increase in BNP concentration, and of >50 pg/mL of ANP increase, successful cardioversion can be predicted with high accuracy. Conclusions: An increase in ANP and stability of BNP plasma concentration during exercise testing are independently associated with successful cardioversion and maintenance of sinus rhythm during 6-month follow-up. © 2010 Wiley Periodicals, Inc.

Intoxication caused by propafenone is very rare, and there are no known detailed epidemiological studies. We present the clinical manifestation of severe propafenone intoxication,successfully treated in a 17 year-old male. He was brought to the Intensive Care Unit after he had taken 3.0 g propafenone. The main clinical findings included: sudden cardiac arrest, coma, hypotension, left ventricular failure, bradycardia, sinoatrial block, atrioventricular junctional or/and ventricular tachycardia. During the treatment, transient heart pacing was performed and catecholamines were administered by means of continuous intravenous infusion of pressure doses as well as of infusion liquids. Cessation of toxic signs four hours after admission to hospital was observed. This relatively rare, fully symptomatic intoxication with propafenone deserved to be presented due to the drug's common usage in the treatment of dysrhythmia and life-threatening symptoms of overdosing. The course of the disease was dramatic and the patient survived only thanks to quick resuscitation, artificial ventilation, transient heart pacing, acidosis treatment and administration of pressure doses of catecholamines. © 2010 Via Medica.

This article presents the effect of the method of NBR cross linking on the thermal properties, flammability and fire hazard of its nanocomposites containing modified montmorillonite (NanoBent or Nanofil), using test results obtained by means of a derivatograph, oxygen index and cone calorimetry. It has been found that the thermal stability and flammability of the nanocomposites investigated depend on both the rubber network structure and the type of montmorillonite. The nanoadditives used reduce the flammability of cross-linked nitrile rubber and considerably limit its fire hazard. © 2011 The Author(s).
