    Background. Post-stroke cognitive impairment is a clinically heterogeneous condition, some types of which cannot be fully differentiated neuropsychologicallyΒ that necessitates the active search for biomarkers. Aims: analyze parameters of neuroinflammation and neurodegeneration inΒ combination with neuroimaging markers in patients with different types of post-stroke cognitive impairment in acute ischemic stroke.Materials andΒ methods. In 72 patients we performed the assessment of cognitive status and distinguished 3 types: normal cognition, dysexecutive, and mixed cognitiveΒ impairment. In each group we determined the concentration of cytokines (IL-1Ξ², IL-6, TNFΞ±, IL-10) in liquor and serum, Ξ²-amyloid 1βˆ’40Β in liquor and a number of MRI morphometric parameters and fractional anisotropy.Results. In all groups of patients we detected higher level ofIL-10 in serum compared with the control. Patients with dysexecutive cognitive impairment had higher concentration of IL-1Ξ², IL-10 in liquor,Β IL-6 level in serum, lower fractional anisotropy of ipsilateral thalamus compared with patients with normal cognition and largest size of infarct.Β Patients with dysexecutive and mixed cognitive impairment had the higher area of leukoareosis and ventricular volume, reduced fractional anisotropyΒ of contralateral cingulum compared with patients with normal cognition. Patients with mixed cognitive impairment characterized by lowerΒ fractional anisotropy of contralateral fronto-occipital fasciculus compared with patients with dysexecutive cognitive deficit.Conclusions. SerumΒ and cerebrospinal fluid concentrations of cytokines studied in combination with MRI parameters particularly fractional anisotropy seems to beΒ informative biomarkers of pathogenic types of PSCI.ОбоснованиС.

    Elemental analysis of archaeological ochre: method and possibilities of X-ray fluorescence spectroscopy (based on materials of Neolithic and Aeneolithic sites of the Middle Trans-Urals and Western Siberia)

    No full text
    The article is dedicated to methodological aspects of the elemental analysis (X-ray fluorescence spectroscopy) of a natural mineral pigment β€” ochre. We chose oxide ochre obtained from the Neolithic and Aeneolithic sites of the taiga zone of Western Siberia and the Middle Urals (the end of VI β€” III millennium BC) as a source base. The questions of selection and preparation of archaeological samples, and of interpretive capabilities of the chosen approach are discussed in the article

    Nutrition in fasting and non-fasting women during the great orthodox lent

    No full text
    Introduction: During the Great Lent orthodox Christians abstain from meat, eggs and dairy for seven weeks. Fish and oils are allowed on certain days only. This leads to substantial changes in diet composition during this period. Aim: To compare nutrition of fasting and non-fasting women in Moscow. Methods: Daily intake of proteins, fats, carbohydrates and their fractions, water- and fat-soluble vitamins, macro-, micro- and ultra trace elements as well as the total caloric content of diet was estimated in 33 fasting and 32 non-fasting women during the Lent. Nutrition was assessed by frequency analysis using Nutrilogic software. Results: Fasting women had significantly higher intake of carbohydrates (412 g vs. 174 g) and fiber (42 g vs. 17 g), but lower intake of cholesterol (74 mg vs. 401 mg) and saturated fats (18 g vs. 30 g). Fasting women were less likely to consume insufficient amounts of vitamins B1 (12% vs. 91%), B3 (52% vs. 91%), B5 (52% vs. 91%), B6 (48% vs. 88%), B9 (42% vs. 94%) and E (24% vs. 72%), potassium (6% vs. 41%), magnesium (21% vs. 91%), iron (18% vs. 81%) and copper (3% vs. 41%). P < 0.001 for all comparisons. All women consumed insufficient amount of vitamin D with food. Conclusion: Diet of fasting women had more favourable macro- and micronutrient composition and was richer in vitamins except vitamin D. This dietary pattern may be associated with health benefits in fasting women. Β©2021 Π³

    Single-Mode W-Type Optical Fiber Stable Against Bending and Radiation

    No full text
    It is shown that single-mode fluorosilicate optical fibers fabricated with the aid of modified chemical vapor deposition exhibit a significant decrease in the radiation resistance when 1 mol % GeO2_{2} is introduced into the silica-glass core. Elimination of chlorine and OH group impurities in the silica glass of the core of the fluorosilicate single-mode fiber leads to a relatively low level of radiation-induced attenuation. Prior to radiation processing, the loss factors of optical fiber are 0.18 and 0.3 dB/km at wavelengths of 1.55 and 1.31 ΞΌm, respectively. The dependence of optical loss of such fibers on the bend diameter ranging from 6 to 12 mm is studied

At the same time, doped carbon coatings are characterized by lower roughness and grain size
