Polish version of standardized noise reaction questions for community noise surveys.

Objectives: This article presents the Polish version of two standardized noise reaction questions for community noise surveys. An internationally comparable noise reaction measure for social surveys was published by Fields et al. as a result of work performed by the Community Response to Noise Team of the International Commission on the Biological Effects of Noise.

Noise duration for a single overflight.

Overflights in national parks and preserves interfere with communication and sounds of nature. The percentage of time that an aircraft is audible, P, can be used as a noise metric. To calculate P the overflight time for a single aircraft, tau, has to be known.

[Our experience with using amrinone in circulatory failure].

A study aimed at evaluating an effect of amrinone of blood circulation dynamics (cardiac output), using impedance ++rheography. The study involved patients with acute, congestive cardiac failure (NYHA III-IV degrees). Cardiac output was measured prior to and 3 and 24 hours following amrinone administration.

Total synthesis of edeine D.

Syntheses of the peptides with sequences postulated for active and inactive isomer of edeine D were carried out. The peptides obtained were identical with natural product in regard to chromatographic and electrophoretic properties. Biological data for synthesized compounds confirmed that in active and inactive isomer isoserine is linked with the alpha- or beta-amino group of alpha, beta-diaminopropionic acid, respectively.

The antibiotic edeine. XII. Isolation and structure of edeine F.

The peptide antibiotic edeine F produced by Bacillus brevis Vm4, one of the components of edeine antibiotics complex, was isolated from a fermentation broth and was also obtained by amidination of edeine D. Edeine F is composed of amino acids: (S)-beta-phenyl-beta-alanine, (S)-isoserine, (S)-2,3-diaminopropionic acid, (2R,6S)-diamino-(7R)-hydroxyazelaic acid, glycine and a polyamine guanidylspermidine. Enzymatic degradation of antibiotic with carboxypeptidase B, dinitrophenylation of edeine and of its enzymatic degradation products and synthesis of edeine F from edeine D of known structure permitted to postulate the chemical structure for edeine F.
