The Centrosomes of Haploid and Diploid Cells Have an Equal Number of Centrioles in the Parasitoid Wasp .

Background: The centrosome is the main center of the organization of microtubules (MT) in the cell, the origin for the formation of flagella and cilia, as well as the site of many regulatory intracellular processes. In diploid cells, the centrosome includes two centrioles connected to some additional structures and surrounded by pericentriolar material.

Methods: The ultrastructure of the cells was studied using transmission electron microscopy on serial ultrathin sections.

Regeneration of Rabbit Auricular Cartilage After the Intravenous Stem Cell Injection.

Background: The restoration of auricular cartilage is a major problem of otolaryngology. The low regenerative capacity of cartilage requires alternative approaches such as cell and tissue engineering. Stem cells are one of the ways to repair auricular cartilage damages.

[Mass spectrometry virulence marker Vibrio cholerae.].

Identification mass-spectrometry of marker proteins of toxicity of V. cholerae for development the express of diagnostics of the causative agent of cholera on the basis of the computer analysis in the MALDI-ToF format of electronic profiles became the purpose of our research. Subjected to the computer analysis mass and spectrometer electronic passports 140 of strains of V.

[The mass-spectrometric analysis of MALDI-TOF in identification and typing of strains of comma bacillus].

The data base “Protein profiles of mass-specters of representatives of species of Vibrio cholerae for program MALDI Biotyper” was used to implement typing of strains of comma bacillus isolated at the territory of the Russian Federation in 2010-2012. Also, analysis of degree of similarity and differences among constant ribosomal proteins was implemented. According the results of MALDI-TOF mass-spectrometry strains of V.

[The time-of-flight mass spectrometer intra-specific diagnostic of strains of Escherichia isolated from patient].

The time-of-flight mass spectrometer analysis of freshly separated human colibacillus populations for identification of markers of proteom specific for hemolytic and non-hemolytic strains, Escherichia-associant of opportunistic enterobacteria. The material consisted of 20 strains of mono-population of hemolytic Escherichia; 100 strains of mono-population of non-hemolytic Escherichia; 15 non-hemolytic strains isolated from association with opportunistic enterobacteria. The protein profiling was implemented on mass spectrometer MALDI-TOF MS Autoflex “Bruker Daltonik”.
