STUDY OF EXPRESSION OF HBD-1 AND HBD-2 GENES IN EPITHELIAL CELLS OF MUCOUS UPPER AIRWAY IN NEWBORNS WITH PNEUMONIA DEPENDING ON THE CAUSATIVE AGENT
Ξ-defensins play an important role in protecting the fetus from infection, so the expression of these antimicrobial peptides in the respiratory tract in newborns is really important. In this regard, we set a task of studying the expression of the HBD-1 and HBD-2 genes in the epithelial cells of the mucous of the upper airway in newborns with pneumonia and in healthy newborns, depending on the causative agent. Also, the polymorphic marker G(-20) A in the DEFB1 gene was associated with infectious pathology of newborns (in particular pneumonia). Methods: The microflora and the factors of congenital immunity on the mucous membranes of the upper airway have been studied in two groups: newborns with ventilator-associated and congenital pneumonia. The biological material was scrapings of epithelial cells of the mucous membrane of the upper airway of newborns and puerperas and blood. Results: It was found that the expression of the HBD-2 gene increases 2.3-fold in children who have an infectious agent, but there are no clinical manifestations of pneumonia. A significant decrease in HBD-2 (3.2 times) in patients with pneumonia caused by K. pneumonia was shown. The frequencies of alleles of the DEFB1 gene in the fetal infection group and in the comparison group: allele G - 0.66, 0.79, allele A - 0.34, 0.21, respectively. The frequencies of the genotypes of the test marker in mothers in the ventilator-associated, congenital pneumonia and the comparison group were as follows: GG - 0.78, 0.58, 0.58; AA is 0, 0.25, 0; AG - 0.22, 0.17, 0.42, respectively. In newborns allele G dominated among alleles (frequency was higher than 0.73 in all groups) and genotype GG (frequency exceeded 0.52). Conclusion: In the course of the study, it was confirmed that Ξ²-defensins protect the mucous from infectious agents. The results indicate that the genetic marker G (-20) A of the DEFB1 gene is associated with the risk of developing the child's UTI

Β Challenges of early kidney cancer detection and screening significantly increase morbidity and mortality rates, thus dictating the need to improve prevention, early diagnosis and organization of medical care for the population of primorsky Krai. The aim of the study was to create a model for improving early diagnosis of kidney cancer in the primorsky Krai using the program for assessing the risk of kidney cancer (ARKC). The model included a population questionnaire to identify risk factors and algorithm of patient routing (Β«roadmapΒ») with suspected kidney cancer for in-depth examination and treatment. Material and Methods. 2982 residents of the primorsky Krai (women β 1950, men β 1032) in the age range 29β75 took part in the questionnaire survey using the ARKC program. Results. No risk factors were identified in 1879 (63.0 %) individuals. All patients at high risk for kidney cancer (656 β 22.0 %) and patients of the uncertainty group (447 β 15.0 %) were referred for physical and ultrasound examination to exclude kidney tumors. Non-tumor pathology of the kidneys was revealed in 156 (14.0 %) patients. Renal mass suspicious for renal cell carcinoma was revealed in 21 (1.9 %) patients (later confirmed in 17 patients with stage IβII cancer, in 3 patients with stage III, in 1 patient with stage IV). According to the results of the factor analysis, two main groups of factors had a predominant effect on the rise in the overall kidney cancer incidencer. The first group of factors (65.0 %) is caused by smoking, excessive alcohol consumption, overweight, unbalanced nutrition, and the influence of carcinogens. The second group of factors (35.0 %) is caused by problems of a medical and social nature: the low material and technical base of primary care medical organizations, the insufficient professional training of medical workers on the issues of cancer prevention and treatment, including kidney cancer.Conclusion. To improve the early detection of kidney cancer, a prognostic model with computer program for assessing the individual risk of developing kidney cancer was developed. population survey using the ARKC computer program allowed us to narrow the diagnostic search, form risk groups and effectively route patients with suspected kidney cancer for in-depth examination in accordance with the Β«road mapΒ».Β Β ΠΡΠΎΠ±Π»Π΅ΠΌΠ° ΡΠ°Π½Π½Π΅ΠΉ Π΄ΠΈΠ°Π³Π½ΠΎΡΡΠΈΠΊΠΈ ΠΈ ΡΠΊΡΠΈΠ½ΠΈΠ½Π³Π° ΡΠ°ΠΊΠ° ΠΏΠΎΡΠΊΠΈ ΡΡΡΠ΅ΡΡΠ²Π΅Π½Π½ΡΠΌ ΠΎΠ±ΡΠ°Π·ΠΎΠΌ Π²Π»ΠΈΡΠ΅Ρ Π½Π° Π·Π°ΠΏΡΡΠ΅Π½Π½ΠΎΡΡΡ ΠΈ ΡΠΌΠ΅ΡΡΠ½ΠΎΡΡΡ ΠΎΡ Π΄Π°Π½Π½ΠΎΠΉ ΠΏΠ°ΡΠΎΠ»ΠΎΠ³ΠΈΠΈ, ΡΡΠΎ Π΄ΠΈΠΊΡΡΠ΅Ρ Π½Π΅ΠΎΠ±Ρ

Preliminary results of the first scientific drilling on Lake Baikal, Buguldeika site, southeastern Siberia
The Baikal Drilling Project (BDP) is a multinational effort to investigate the paleoclimatic history and tectonic evolution of the Baikal sedimentary basin during the Late Neogene. In March 1993 the Baikal drilling system was successfuly deployed from a barge frozen into position over a topographic high, termed the Buguldeika saddle, in the southern basin of Lake Baikal. The BDP-93 scientific team, made up of Russian, American and Japanese scientists, successfully recovered the first long (\u3e100 m) hydraulic piston cores from two holes in 354 m of water. High quality cores of 98 m (Hole 1) and 102 m (Hole 2), representing sedimentation over the last 500,000 years, were collected in 78 mm diameter plastic liners with an average recovery of 72% and 90%, respectively. Magnetic susceptibility logging reveals an excellent hole-to-hole correlation. In this report the scientific team describes the preliminary analytical results from BDP-93 hole 1 cores. Radiocarbon dating by accelerator mass spectrometry provides an accurate chronology for the upper portion of Hole 1. Detailed lithologic characteristics, rock magnetic properties and inorganic element distributions show a significant change to the depositional environment occuring at 50 m subbottom depth, approximately 250,000 BP. This change may be due to uplift and rotation of the horst block in the Buguldeika saddle. The sedimentary section above 50 m is pelitic with varve-like laminae, whereas the section below 50 m contains a high proportion of sand and gravel horizons often organized into turbidite sequences. Accordingly, high resolution seismic records reveal a change in sonic velocity at this depth. It is inferred that sedimentation prior to 250 ka BP was from the west via the Buguldeika river system. After 250 ka BP the Buguldeika saddle reflects an increase in hemipelagic sediments admixed with fine-grained material from the Selenga River drainage basin, east of Lake Baikal. Variations in the spore-pollen assemblage, diatoms, biogenic silica content, rock magnetic properties, clay mineralogy and organic carbon in the upper 50 m of BDP-93-1 reveal a detailed record of climate change over approximately the last 250,000 years. These variables alternate in a pattern characteristic of glacial/interglacial climatic fluctuations. The present age model suggests that the climate signal recorded in Lake Baikal sediments is similar to Late Quaternary signals recorded in Chinese loess sections and in marine sediments.
