18 F-FDG PET Metabolic Parameters for the Prediction of Histological Response to Induction Chemotherapy in Osteosarcoma and Ewing Sarcoma : A Systematic Review and Network Meta-analysis.

Purpose: This study aimed to evaluate the ability of 18 F-FDG PET/CT metabolic parameters to predict the histological response to neoadjuvant chemotherapy in patients with osteosarcoma and Ewing sarcoma.

Patients And Methods: This systematic review and network meta-analysis adhered to the PRISMA-NMA and Cochrane guidelines. Electronic databases were searched from January 2008 to January 2024; this search was supplemented by snowballing methods.

[The complex evaluation of condition of intestinal and nasopharyngeal microbiocenosis in alumni of children's home].

The examination of nasopharyngeal and intestinal microbiocenoses was implemented in orphan children aged 1-3 years residing in children;s home of Cheremkhovo of the Irkutskaia oblast. All children had compromised anamnesis: prematurity, hypotrophy, chicken pox, frequent acute respiratory viral infections, intestinal infections, atopic dermatitis. The study was carried out to comprehensively evaluate conditions of intestinal and nasopharyngeal biotops in children residing in closed children’s institution - children’s home.

[The micro-ecological characteristic of intestinal biocenosis of children with functional disorders of gastrointestinal tract].

The study was carried out to investigate micro-ecological characteristics of intestinal microbiocenosis in children with functional disorders of gastro-intestinal tract. All patients were applied general clinical and laboratory examination (feces microscopy and analysis on intestinal dysbacteriosis). The micro-ecological coefficients were calculated i.

[THE SPECIES CHARACTERISTIC OF BIFIDOBACTERIA IN INTESTINAL BIOTOPE OF CHILDREN WITH FUNCTIONAL DYSPEPSIA].

The study was carried out to investigate species specter and combinational variety of bifidobacteria in children with functional dyspepsia. The examined sampling included 73 children with functional dyspepsia aged from 4 to 6 years. The comparison group according common characteristic of microbiota of large intestine included 100 healthy children comparative by age.

[The structure of intestinal dysbioses in children of preschool age during long-term period of monitoring].

The study was organized to examine long-term (1990-2011) structure of intestinal dysbioses in children of preschool age residing in Irkutsk. The significant decrease of expression of micro-ecological shifts (IV and III degrees) to the end of period of monitoring and almost total lacking of cases of eubiosis and statistically reliable (p ≤ 0.05) increasing of rate of dysbioses of I and II degrees were established.

[The detection of occurrence rate of genes coding capability to form pili binding in auto-strains of Escherichia coli].

E. coli is a commensal of intestine of the vertebrata. The exchange of genetic material of different types of bacteria between themselves and with other representatives of family of Enterobacteriaceae in intestinal ecosystem results in development of types of normal colibacillus with genetic characteristics of pathogenicity that can serve as a theoretical substantiation to attribute such strains to pathobionts.

[The detection of strains of Esherichia coll producing Shiga toxin in populations of normal intestinal microbiota in children with functional disorders of gastrointestinal tract].

In intestinal ecosystem, interchange of genetic material between different types of bacteria and other representatives of family Enterobacteriaceae results in development of types of normal colibacillus with genetic characteristics of pathogenicity. This occurrence can be considered as a theoretical substantiation for labeling such strains as pathobionts. The polymerase chain reaction was implemented to analyze 96 strains of different types of Escherichia coli (with normal and weak zymogenic activity and hemolytic activity) isolated from children with functional disorders of gastrointestinal tract.

[The formation of intestinal microbiocenosis in children in the industrial cities of Siberia].

The purpose of this study was to investigate the features of the formation of intestinal microbiocenosis in children residing in the industrial cities of Siberia. The study included 168 healthy children. There is presented the medical and hygienic assessment of the examined area with bearing in mind the degree and specificity of the man-made pollution of the atmosphere.

[The specific features of microbiocenoses in children living under conditions of anthropogenic pressing].

The specific features of enteric and nasopharyngeal microbiocenoses and the species composition of bifidobacteria have been studied in children living in the industrial towns of the Irkutsk Region under the existing anthropogenic load. Ambient air pollution is characterized and a presumptive human health risk assessed.

TEM and HREM of diamond crystals grown on Si tips: structure and results of ion-beam-treatment.

Diamond single crystals were grown on the silicon whiskers by a hot filament chemical vapor deposition technique at the filament temperature about 2100 degrees C and the temperature of support 800 degrees C. Specimens were examined by SEM, TEM, HRTEM and SAED. When the filament temperature was about 1900 degrees C globular polycrystalline diamond particles were grown.
