Modulating aryl substitution: Does it play a role in the anti-leishmanial activity of a series of tetra-aryl Sb(V) fluorinated carboxylates?

Eight tetra-arylantimony carboxylates of the general formula ArSbOC(O)R with Ar = Ph (a), p-Tol (b), R = CF (1), CHCF (2), CFBr (3), CFCFCF (4) have been synthesised and characterised. Two of them (2b, 3b) are structurally novel. All structures were analytically characterised by FT-IR, H, C NMR spectroscopy.

Digital Identification of the Human Condition as a Prerequisite for the Effectiveness of the Organizational Automation (Biocybernetic) Systems Operation.

The article deals with the problems of improving modern human-machine interaction systems. Such systems are called biocybernetic systems. It is shown that a significant increase in their efficiency can be achieved by stabilising their work according to the automation control theory.

[Taxonomic relations between forms in evolutionary young complexes of lepidopterans (Insecta, Lepidoptera)].

Morphological characteristics of the prototype wing pattern can be used in lepidopteran population studies as markers of population groups and interpopulation boundaries. The centers of phenotypic variation serving as speciation centers were recognized within the range of polytypic species. Revision of the polytypic complex Polyommatus icarus Rott.

[Bronchial reactivity and mucosal bioamines as criteria for acute bronchitis becoming chronic].

Aim: To study bronchial reactivity and sensitivity with consideration of histamine, serotonin and catecholamines concentration in bronchial mucosa in patients with acute bronchitis (AB) as possible criteria of its becoming chronic.

Material And Methods: Before the treatment 116 patients with verified AB were examined using inhalation provocative tests (IPT) with histamine, serotonin and obsidian in increasing doses. Also, external respiration function was studied.
