The changes in the amino and fatty acid profiles in the semifinished foodstuffs based on broiler meat and components of chicken eggs after different types of thermal treatment

The changes in the amino and fatty acid profiles in the semifinished foodstuffs (SFFs) based on broiler meat and coagulated chicken egg melange after different types of thermal treatment (water or steam boiling, braising, baking, frying) were studied. The amino acid profiles were determined on Knauer analyzer; tryptophan by standard method. The biological value of the treated products was assessed using amino acid balance coefficients calculated by the method of N. N. Lipatov. It was found that the changes in the initial amino acid profiles of the SFFs were the least after water and steam boiling; braising and baking were found to increase the contents of the essential amino acids. The amino acid profiles in the treated SFFs were close to the reference values. The best criteria of their biological value (coefficient of rationality of amino acid composition, comparable redundance) were found after water and steam boiling. It was found that all types of thermal treatments insignificantly affected the parameters of fatty acid balance within the SFFs; the changes found were primarily related to slight increase in total content of saturated fatty acids and increase in total content of polyunsaturated fatty acids (PUFAs) in compare to initial profiles, by 2.64–3.88% depending on the treatment type. The changes in ω‑6/ω‑3 PUFAs ratios were more substantial especially after braisin

NMR analysis of the composition of essential oil of fur during its evaporation

Comparative analysis of the composition of essential oil of fir during its evaporation in air for 12 weeks by method of NMR 1 H and 13 C was carried out. 12 major essential oil components were identified and quantified. It was found that the compositional change of essential oil is reflected experimentally in the quantitative content of components, and caused mainly by evaporation of highly volatile compounds. The oxidation and polymerization processes in new products approve themselves slightly

Study of the association of gene polymorphism with the risk of non-communicable diseases in martial artists

Objective: to study the effect of genetic polymorphisms: rs rs9939609 (FTO gene), rs4994 (ADRB3 gene), rs1042713 (ADRB2 gene), rs2228570 (VDR gene), rs1801133 (MTHFR gene) on anthropometric and lipid metabolism indicators in athletes representing martial arts.Materials and methods: studies of anthropometric and biochemical parameters, genetic polymorphisms were carried out in 120 athletes (101 men and 19 women) who are engaged in martial arts. Anthropometric studies were performed by measuring height (cm), body weight (kg), followed by calculating body mass index (BMI, kg / m2). Biochemical nutritional status markers were determined using the ABX Pentra 400 analyzer (HORIBA ABX SAS, France) in an automatic mode. Genotyping was performed using allele­specific amplification using TaqMan probes complementary to polymorphic DNA regions and real­time detection of the results using reagent kits from Syntol, Russia. Studies were performed on the device CFX96 Real Time System (Bio­Rad, USA). Statistical processing of the results was performed using the PASW Statistics 20 system.Results: as a result of generic Diovan athletes martial artists on the risk of non­communicable diseases, discovered that the frequency of allele A of rs9939609 polymorphism of the FTO gene they have is 43.9 %, allele polymorphism rs4994 ADRB3 gene — 10.9 %, G allele of rs1042713 ADRB2 gene polymorphism — 52.6 %, G allele of the polymorphism rs2228570 VDR gene with 44.9 % and allele t of rs1801133 in the MTHFR gene to 36.7 %. An association was found between the value of anthropometric indicators in male martial artists and the presence of polymorphisms rs9939609 (FTO), rs1042713 (ADRB2) and rs2228570 (VDR).Conclusions: the reason for the identified dyslipidemia in martial artists may be not only the previously detected violations of the structure of their nutrition, but also the presence of certain genetic polymorphisms, in particular, rs4994 of the ADRB3 gene and rs1042713 of the ADRB2 gene

Study of Association of gene polymorphism with nutrition and nutritional status of martial arts athletes

Objective: studying the effect of genetic polymorphisms: rs1815739 (ACTN3 gene), rs2016520 (PPARD gene), rs1042713 (ADRB2 gene), rs1799945 (HFE gene) on anthropometric and lipid metabolism indicators in athletes representing martial arts. Materials and methods: studies of anthropometric and biochemical parameters, genetic polymorphisms were carried out in 83 athletes (64 men and 19 women) who were are engaged in martial arts. Anthropometric studies were performed by height (cm) and body weight (kg) measuring followed by calculating body mass index (BMI, kg / m2). Biochemical nutritional status markers were determined using the ABXPENTRA 400 analyzer (HORIBA ABX SAS, France) in an automatic mode. Genotyping was performed using allele-specific amplification using TaqMan probes complementary to polymorphic DNA regions and realtime detection of the results using reagent kits from Syntol, Russia. Studies were performed on the device «CFX96 Real Time System» («BIO-RAD», USA). Statistical processing of the results was performed using the PASW Statistics 20 system. Results: as a result of gene testing for endurance of combat athletes, it was found that the frequency of the T allele of the rs1815739 polymorphism (ACTN3 gene) was 47.5%, the PPARD gene ал20120120 allele G is 13.9%, the rs1042713 G allele of the ADRB2 gene was 51.9%, and the G allele of the rs1799945 polymorphism of the HFE gene was 19.3%. No association was found between the value of anthropometric parameters in athletes and the presence of the studied polymorphisms. Conclusions: the cause of identified dyslipidemia in combat athletes may be not only the disturbances in the structure of their nutrition that we found earlier, but also the presence of certain genetic polymorphisms

Role and Place of PET/CT in the Assessment of Skin Melanoma Prevalence

Skin melanoma is potentially the most dangerous form among all tumor skin lesions. According to statistics, melanoma accounts for about 90% of deaths. The cause of high mortality of patients is early metastasis. At the same time, melanoma metastases can be localized in almost all organs and tissues. In addition to local and regional metastasis to the skin, subcutaneous tissue and lymph nodes, metastatic melanoma of distant organs is not uncommon, and this dramatically worsens the prognosis of the disease. High-quality instrumental diagnostics at various stages of patient management (from primary diagnosis to treatment control) allow to reduce mortality and increase the overall survival of patients. Positron emission tomography in combination with computed tomography (PET/CT) has been used in the last decade as a dominant imaging method for initial staging, control of treatment and detection of progression or recurrence of various types of cancer, including melanoma. It is of great practical importance for predicting survival outcomes, assessing the risk of disease progression, as well as the effectiveness of radiation and systemic therapy. It is PET/CT that allows to simultaneously evaluate the condition of all organs and tissues with minimal radiation load being more sensitive and specific imaging method in comparison with ultrasound, CT and magnetic resonance imaging. PET/CT with <sup>18</sup>F-fluorodeoxyglucose is the most effective method for early detection of asymptomatic melanoma recurrence. In addition to accurate setting the tumor process stage, this method is crucial to ensure adequate and effective treatment, which in turn will increase the life expectancy of this category of patients in the near future
