E. coli aggregation and impaired cell division after terahertz irradiation.

In this study we demonstrated that exposure of Escherichia coli (E. coli) to terahertz (THz) radiation resulted in a change in the activities of the tdcABCDEFGR and matA-F genes (signs of cell aggregation), gene yjjQ (signs of suppression of cell motility), dicABCF, FtsZ, and minCDE genes (signs of suppression of cell division), sfmACDHF genes (signs of adhesin synthesis), yjbEFGH and gfcA genes (signs of cell envelope stabilization). Moreover, THz radiation induced E.

Complexes of Metal Halides with Unreduced -(Imino)quinones.

A series of complexes of metal halides with unreduced quinone-type ligands have been synthesized and characterized in detail. The 3,6-di--butyl--benzoquinone () and 4,6-di--butyl--aryl-substituted -iminobenzoquinones (-) (aryl is 2,6-dimethylphenyl in , 2-methyl-6-ethylphenyl in , 2,6-diethylphenyl in , and 2,6-diisopropylphenyl in ) were used to obtain the molecular complexes with metal 12 group halides as well as with indium(III) iodide. The molecular structures of five complexes, bearing an unreduced form of redox-active ligand, have been established by single-crystal X-ray analysis.

Changes in the proteomic profile of blood serum in coronary atherosclerosis.

Background: Our aim was to study changes in the serum proteomic profile in coronary atherosclerosis.

Methods: The study involved two groups of patients: 1) men with coronary heart disease and coronary atherosclerosis (n = 15); 2) control (n = 15): men without coronary heart disease. The object of this study was blood serum.

A Proteomic Study of Atherosclerotic Plaques in Men with Coronary Atherosclerosis.

Background: To study the changes in protein composition of atherosclerotic plaques at different stages of their development in coronary atherosclerosis using proteomics.

Methods: The object of research consisted of homogenates of atherosclerotic plaques from coronary arteries at different stages of development, obtained from 15 patients. Plaque proteins were separated by two-dimensional electrophoresis.

An intrinsically disordered linker controlling the formation and the stability of the bacterial flagellar hook.

Background: In a macro-molecular complex, any minor change may prove detrimental. For a supra-molecular nano-machine like the bacterial flagellum, which consists of several distinct parts with specific characteristics, stability is important. During the rotation of the bacterial flagellar motor, which is located in the membrane, the flagella rotate at speeds between 200 and 2000 rpm, depending on the bacterial species.
