The addition of aqueous perchloric acid to I at room temperature leads to the adsorption compound formation.

[Clinical and morphological diagnosis of secondary hemophagocytic lymphohistiocytosis].

Secondary hemophagocytic lymphohistiocytosis (hemophagocytic syndrome, massive macrophage activation syndrome) is a rare, aggressive, severe syndrome with a frequent fatal outcome. The pathogenesis of the syndrome, the role of viral infection, and the development of an excessive, aberrant, and inflammatory response leading to multiple organ dysfunction and sepsis remain unclear so far. The paper presents the data available in the literature and describes the authors' own observation of secondary hemophagocytic lymphohistiocytosis in a 14-year-old girl who had Epstein-Barr virus infection and died of severe multiple organ dysfunction.

High-Throughput Fingerprinting of Rhizobial Free Fatty Acids by Chemical Thin-Film Deposition and Matrix-Assisted Laser Desorption/Ionization Mass Spectrometry.

Fatty acids (FAs) represent an important class of metabolites, impacting on membrane building blocks and signaling compounds in cellular regulatory networks. In nature, prokaryotes are characterized with the most impressing FA structural diversity and the highest relative content of free fatty acids (FFAs). In this context, nitrogen-fixing bacteria (order Rhizobiales), the symbionts of legumes, are particularly interesting.

[The etiologic structure and biologic characteristics of agents of infections of bloodstream.].

As before, the infections of blood flow remain actual because of absence of universal approaches to their diagnostic and high lethality. Taking into account the fact that most frequently the sepsisogenic strains are selected in blood, studying of biological characteristics of hemocultures in comparison with strains isolated from other biotopes is very important for understanding the mechanisms of survival of pathogens in blood and prognosis development of septic complications. The article presents the results of microbiological analysis of blood carried out in multi-field clinic of Khanti-Mansiisk during 2007-2015.

Were identified specific and meaningful for computer work physiological functions in children of 5-6 years: a functional motility of nervous processes, the function of the motor analyzer (accuracy of hand kinesthesia), the functional state of the eye accommodative system, mental capacity, volume and concentration, shortterm memory function. A considerable number of preschoolers (47%) set high enough level of development of organism functions necessary for successful interaction with the computer.

[Transforming growth factor as a marker beta of nephrogenetic disturbance in congenital obstructive uropathies].

The paper presents the results of morphological and immunohistochemical studies of the kidneys and ureters obtained at surgery in 25 children aged from 2 days to 3 years who had congenital obstructive uropathies. The morphological study revealed varying renal tissue dysplasia concurrent with dysplasia of the prepelvic or distal ureter. Immunohistochemically, the kidneys showed a pronounced expression of TGFbeta1, TGF(1R1 and R2 in the nephrocytes of non-differentiated and collecting tubules, in the tubular lumen, vascular walls, in the interstitial tissue and cell interstitial infiltrates, on the hypoplastic and disoriented ureteral smooth muscle fibers.

[Renal development long after correction of primary non-refluxing forms of megaureter in children].

We studied the condition and development of 50 kidneys in 45 patients 10-30 years after surgical correction of megaureter. We made resection and neoimplantation of the ureter according to the antireflux technique. By x-ray findings, we estimated area of the kidney, renocortical index and compared them with visual assessment of the condition of the kidney and its pelvicocalicyal system.

alpha-Defensins from blood leukocytes of the monkey Papio hamadryas.

Three antimicrobial peptides named PHD1-3 (Papio hamadryas defensin) have been isolated from hamadryas baboon blood leukocytes using preparative electrophoresis and reverse-phase HPLC. The primary structures of these peptides have been determined by automated Edman degradation and mass-spectrometry. The results suggest that the peptides belong to the alpha-defensin family.

Singularity of proton transport in salts of orthoperiodic and orthotellurium acids: theoretical modeling using density functional calculations.

Density functional B3LYP calculations have been performed to investigate proton transport in orthoperiodic and orthotellurium acids, their salts MIO(6)H(4)(M = Li, Rb, Cs) and CsH(5)TeO(6), dimers of the salt*acid type MIO(6)H(4)*H(5)IO(6)(M = Rb, Cs), CsIO(6)H(4)*H(6)TeO(6), CsHSO(4)*H(6)TeO(6), Cs(2)SO(4)*H(6)TeO(6), and also in double-substituted and binary salts Rb(2)H(3)IO(6) and Rb(4)H(2)I(2)O(10). It has been shown that the energy of salt dimerization is 33-35 kcal mol(-1) and the activation barrier for proton migration between the neighboring octahedrons of the salt*acid --> acid*salt type is calculated to be 3-13 kcal mol(-1). The activation energy of the proton migration along the octahedron, 20-30 kcal mol(-1), is comparable with the barrier for water molecule separation.
