The work is devoted to studying the metabolites composition for human urine of prostate cancer and benign prostatic hyperplasia patients by terahertz (THz) high-resolution gas spectroscopy. comparison formed during thermal decomposition collected with preliminary massage, without massage was carried out. THz spectrometer 118-178 GHz frequency range fast sweeping developed authors used. Free online spectroscopy databases were used identification substances. sets two types samples are revealed...

Major changes in the Holocene were identified based on a diatom and geochemical analysis of sediment cores from Lakes Ufimskoe Syrytkul (the Southern Urals). The Lake ecosystem Central mountain area is to be highly sensitive variations temperature. Meanwhile, more responsive climate aridization because its limnological characteristics less precipitation piedmont area. Climate events main drivers for lake ecosystems dynamics throughout almost whole history lakes. records sediments reflect...

Object. Multi-proxy analysis of 265 cm long sediments core Lake Turgoyak, one the deepest lakes Southern Urals, is presented. Materials and methods. The lake ecosystem changes was reconstructed based on diatom, radiocarbon dating geochemical analysis. Statistical treatment surface composition hydrochemistry data 56 from Middle Urals database allowed to obtain indexes for reconstruction water parameters: index organic matter content (ОМ = LOI550ºС/(Al2O3 + TiO2 Na2O K2O)) salinity (ММ...

Oral mucositis is the most common and significant complication of chemoradiation therapy for oral pharyngeal cancer. There are no standard methods preventing treating this disease. Patients with severe adverse events need expensive supportive care unplanned treatment breaks. The objective study was to assess optimize effectiveness low level laser (LLLT) prevention chemoradiation-induced in patients Material Methods. Forty-eight who received cancer were enrolled. All randomly divided into two...

Abstract Analytical data on major and trace elements concentrations in lake sediments are frequently applied a wide range of limnological, paleolimnological, environmental studies. Conventionally methods characterized by time‐consuming, expensive, (or) hazardous sample preparation. The proposed express method simultaneous multi‐element determination laser ablation inductively coupled plasma mass‐spectrometry (LA‐ICP‐MS) pressed powdered pellets comprises minimal preparation, special...

The article is devoted to the description of software products created with help information technologies for study lakes in Urals. LaDa database contains about 107 Urals and allows you conduct a multivariate search using morphometric parameters data from diatom, hydrochemical geochemical analysis visualize results on map. diatom identification “DiatomDB” collection collected systematized by authors, allowing one identify species based set observed characteristics, strict non-strict search,...

Lake Turgoyak development through more than 12 thousand years was studied based on diatom analysis of the lake sediment core. Altogether 142 taxa were identified. Four zones corresponding to main stages ecosystem distinguished with application stratigraphically constrained cluster analysis. It found that in period from 12.1 11.0 cal ka BP had maximum salinity and a high degree overgrowth hydrophytes. Desalination an increase depth occurred between 7.7 BP. Substantial fluctuations parameters...

The study objective is to demonstrate the necessity of individual selection radiation plan in patients with locally advanced squamous-cell oropharyngeal cancer after multicomponent operation decrease radioreactions and injuries. Materials methods . included data on 64 primary combination treatment at Nizhny Novgorod Regional Clinical Oncological Dispensary 2013–2018. Radiation was performed surgeries. 1st group 30 who underwent conformal using linear accelerators. 2nd 34 conventional...

Breast cancer (BC) is one of the most common malignancies and leading cause cancer-related death in women worldwide. Currently, mammography ultrasound are methods commonly used for detection BC, but these have significant limitations absence “classic” visual symptoms breast tissue. In complicated clinical situations, such as magnetic resonance imaging positron emission tomography differential diagnosis cancer. Over past 20 years, BC capabilities expanded due to introduction optical into...

This paper presents the diatom data on Holocene sediments of Lake Tavatui (Middle Urals, Russia). The dataset includes abundances 160 taxa and quantitative reconstructions total phosphorus electrical conductivity lake water through more than 11.7 cal ka BP. Diatom identification was performed using a Mikmed 6 var. 7 microscope, bright-field oil immersion optics at 1000 × magnification. At least 500 valves were counted to determine relative in assemblages (diatom total, percentage)....

Research subject. The Lake Sabakty sediments core, as a source of data on the Holocene and Lateglacial environments in Southern Urals. Aim. To obtain multiple regression model for quantitative reconstructions electrical conductivity water based geochemistry lake to reconstruct Late Glacial study geochemical record. Materials methods. After determination correlations between content chemical elements hydrochemical parameters 107 Ural lakes, models were obtained. Reconstructions performed...

Changes of deep mountain-steppe oligo-mesotrophic lake Yaktykul (Bannoe) over the past 230 years were studied based on diatom analisis sediments core. Identified species and varieties diatoms (126) represented mainly by planktonic-benthic alkaliphiles, oligohalobes, β-mesosaprobes oligosaprobes. Five zones distinguished. Small cyclic (Stephanodiscus parvus, Pantocsekiella comensis) increase in upper part sediment core was observed. total phosphorus (TP) concentration reconstructed. Until...
