Biomarker for alzheimer's disease or mild cognitive impairment Invention relates to the field of medicine, namely to a method of diagnosing Alzheimer's disease or a mild cognitive impairment. The essence of the method consists in the fact than the method includes the measurement of desmosterol, beta-amyloid, and gelsolin in blood. If the desmosterol level in the subject's blood is below the standard value, or if the desmosterol level and Aβx-42 or Aβx-42/Aβx-40 in the subject's blood are below the standard values, or if the desmosterol level and Aβx-42 or Aβx-42/Aβx-40 and the level of helsolin in the subject's blood are below the standard values, Alzheimer's disease or a mild cognitive impairment are diagnosed. |

Method of separating and determining iron (iii) and iron (ii) Method includes preparing a solution containing iron (III) and iron (II), creating the necessary pH, reacting the solution with a sorbent, measuring the diffuse reflection factor at 500 nm and determining iron content from a calibration curve, where in order to separate iron from the solution in different oxidation states, the sorbent used is silica which is successively modified with polyhexamethylene guanidine and pyrocatechol-3,5-disulphonic acid, wherein iron (III) is separated from the solution with pH=3, and then iron (II) from the solution with pH=6. |

Analysis for quantitative determination of clostridial neurotoxin Invention relates to the field of biochemistry, namely to a method of determining an unknown concentration of a clostridial neurotoxin in the first sample with respect to a known concentration of the clostridial neurotoxin in the second sample and to a method for determining the relative activity of the clostridial neurotoxin in the first sample relative to the activity of the clostridial neurotoxin in the second sample, where the method includes the following stages: (a) contact of a cell culture with the said second sample, containing the clostridial neurotoxin in the known concentration; (c) measurement of the second effect, caused in the said cell culture by the said clostridial neurotoxin in the known concentration; (d) repetition of stages (a)-(c) with different concentrations of the said clostridial neurotoxin; (e) registration of the measured second effect of stage (d) depending on the concentration of the clostridial neurotoxin with the registration, in such a way, of the second set of data; (f) contact of the cell culture with the said first sample, containing the said clostridial neurotoxin in the unknown concentration; (h) measurement of the first effect, caused in the said cell culture by the said clostridial neurotoxin in the unknown concentration; (k) determination of the concentration of the clostridial neurotoxin, at which the said first and the said second effects are identical; and (l) comparison of the concentration of the clostridial toxin, determined in (k), with the said unknown concentration of the clostridial neurotoxin; where before the said measurement at stage (c) and stage (h) and after contact at stage (a) and stage (f) the said cell structure is subjected for 0.5 to 100 h to contact with a water medium, which does not contain the clostrdial neurotoxin, and where stage (c) is performed in case the said second sample is missing, and stage (h) is performed if the said first sample is missing. Application of the method for the determination of the unknown concentration of the clostridial neurotoxin in the first sample relative to the known concentration of the clostridial neurotoxin in the second sample is described. |

That is ensured by using an enzyme immunoassay to measure patient's oral fluid biomarkers prior to or at least 30 min after meals. The above biomarker is matrix metalloproteinase 2 (MMP 2) or matrix metalloproteinase 8 (MMP 8). For a clinical reference group, MMP 2 is adopted as 1.89-2.69 ng/ml; if the observed level is 4.2-6.6 ng/ml, the low adaptation ability is diagnosed; the level of 2.9-3.8 ng/ml shows the complete functional adaptation in the patient suffering dentofacial new growths to removable appliances of prosthetic dentures. For a clinical reference group, MMP 8 is 21.65-41.85 ng/ml; if the observed level is 433.0-1,011.6 ng/ml, the low adaptation ability is diagnosed; the level of 52.8-186.3 ng/ml shows the complete functional adaptation in the patient suffering dentofacial new growths to removable appliances of prosthetic dentures. |

Early diagnostic technique for primary open-angle glaucoma Invention refers to medicine, namely to ophthalmology, and can be used for the early diagnosis of primary open-angle glaucoma. That is ensured by measuring and assessing an intraocular pressure, examining visual fields and lachrymal fluid, measuring pro-inflammatory and anti-inflammatory cytokines and additionally measuring them in blood serum. If observing an increase of blood serum IF-γ/IL-4, IL-1β/IL-10, TNF-α/IL-10 in the patients with suspected glaucoma, cytokine coefficients equal to 3.66±1.77, 1.9±0.47, 1.20±0.32 respectively in the patients suffering the initial stage of open-angle glaucoma, the relations IF-γ/IL-4, IF-γ/IL-10, IL-1β/IL-10, TNF-α/IL-10, cytokine coefficients equal to 1.85±0.44, 1.48±0.34, 2.85±0.74, 2.42±0.71 respectively, as well as an increase of lachrymal IF-γ/IL-4, IF-γ/IL-10, IL-1β/IL-10, TNF-α/IL-10 in the patients with suspected glaucoma, cytokine coefficients equal to 1.11±0.19, 1.06±0,09, 3.81±0.63, 4.04±0.36 respectively, and in the patients with the initial stage of open-angle glaucoma, an increase of IF-γ/IL-4, IF-γ/IL-10, IL-1β/IL10, cytokine coefficients equal to 1.26±0.22, 0.84±0.08, 3.98±0.61 respectively, primary open-angle glaucoma is diagnosed. |

Method of determination of fire resistance of brick columns with mortar holder Brick columns are tested without destruction by a complex of single parameters of quality, estimating the value of the actual degree of fire resistance by the loss of bearing capacity. For this purpose the geometrical sizes of brick columns with mortar holder, conditions of heating of columns, the value of the longitudinal bend coefficient, the parameters of thermal diffusion of material of brick columns and mortar of the holder, percentage of indirect reinforcing of brickwork; the value of standard loads during fire resistance test and level of tension of hazardous cross sections of brick walls. A degree of fire resistance of brick columns with a mortar holder is determined by the evidence of losses of bearing capacity. |
