Research of the overall chemical and amino acid composition of meat from young animals of new sheep genotypes

The paper presents the results of the investigation of the overall chemical composition (mass fraction of moisture, fat, protein and ash) and the amino acid composition of mutton from the experimental animals of new genotypes: Sovetsky Merino x Dzhalginsky Merino and Sovetsky Merino x Stavropolsky breed. As a control, meat of purebred Sovetsky Merino was studied. The experimental and control rams were slaughtered at the age of 8 months by the conventional technology. Meat samples for laboratory examination were taken a day after slaughter. The results of the analysis of the overall chemical composition showed that lamb meat of new genotypes had lower moisture content and higher content of fat and protein compared to the control. Analysis of the amino acid composition of meat proteins of genotypes Sovetsky Merino x Dzhalginsky Merino and Sovetsky Merino x Stavropolsky breed revealed lower content of essential amino acids compared to the control. Comparison of amino acid scores showed that the amino acid composition of meat proteins from the experimental animals was limited by valine and lysine, respectively. It was concluded by the results of the investigations of the amino acid composition of proteins that the biological full value of proteins of mutton from new genotypes was 22.9% and 30.3% lower than that of the control

Age and growth of blue Antimora Antimora rostrata (Moridae) in Southwestern Greenland waters

The results of determination of age and study on growth of blue antimora Antimora rostrata from the waters of Southwestern Greenland are presented. The results are based on the analysis of 200 fish otoliths. In the catches, we found specimens of antimora with total lengths of 18−70 cm, body weights of 23−2731 g, at the age of 7−38 years. Minimal age of males (not considering juvenile individuals) was 10 years at body length of 27−33 cm; maximal age was 18 years at 42 cm. Minimal age of females was 9 years at length of 21–27 cm; maximal age was 38 years at 70 cm. The rate of linear growth in blue antimora from Southwestern Greenland waters is comparable to that in the fish from New Zealand and Ross Sea waters but considerably lower than indicated earlier for fish from the waters of Iceland, Greenland, and the Mid-Atlantic Ridge. The age of reaching sexual maturity in males and females is preliminary determined as 15 and 19−20 years, respectively

Growth and age of the roughhead grenadier Macrourus berglax in waters off Southwest Greenland

Data on the age and growth of the roughhead grenadier Macrourus berglax from waters off Southwest Greenland have been obtained based on the analysis of otoliths. Specimens with a preanal length of 5−39 cm, a weight of 7−5275 g, and age from 2 to 22 years are recorded in trawl catches. Roughhead grenadier exhibits a similar rate of linear growth in waters off Southwest Greenland and other parts of the range in the Northwest Atlantic. No considerable differences from the rate of the linear growth calculated earlier from scales for the species in waters off West Greenland have been found. In the recent period, the rate of weight gain in roughhead grenadier in waters off Southwest Greenland has been lower than in the Northwest Atlantic in the first half of the 1980s. The age of mass maturation in males (7–9 years) and females (16–17 years) in waters off West and East Greenland is somewhat higher than in coastal waters of Norway and the Northwest Atlantic

Analysis of the physical fitness of students in accordance with the norms of the All-Russian sports complex «Ready for labor and defense» with regard to somatic type

Objective: to detect the relationship between body types (somatotype) and successful passing of the standards of «Ready for Labor and Defense-2014» in students-boys of 18-20 years old. Materials and methods: the study involved 82 male students. The method of somatotyping by Dorokhov RN, Petrukhina VG (1989) was used to determine the body types. The overall and component level of variation was defined. We used the results of passing the test standards and compared them with data on the implementation of the norms of GTO in some types of tests: 100-meters race, 3000-meters race, pulling out from suspension on high bar, standing long jump using double-legged take-off. Results: the muscle mass dominates in all somatic groups, which corresponds to macromuscular type (0,509-0,799). The representatives of microsomatiс type have the highest results - 0.7. When comparing the results of tests of «pulling out from suspension on high bar» with the standards of GTO 2014 6 stage, the best results were found in microsomes group: 90.5% of the subjects completed the specification and received the gold badge, 4.8% of the subjects received the bronze badge, 4.8% of the subjects failed tasks. In mesosomes group only 60% of the subjects fulfilled the standard of «pulling-up» and received the gold badge, 33.33% of the subjects received the silver badge, 6.67% of the subjects did not fulfill the norm. While analyzing the results of «standing long jump using double-legged take-off» more successful results were obtained in the MaC group: 46.67% received the gold badge, 33.33% received the silver badge, 16.67% received the bronze badge, 3.33% did not fulfill the norm. Conclusions: assessing the anthropometric and functional parameters of the organism of students, it is necessary to consider not only the average age range, but also pay attention to the constitutional-typological features

Primary dismernoria among teenager girls on the background of non-differentiated dysplasia of connecting tissue

Objective of the study: to identify the features of the primary dysmenorrhea clinic among adolescent girls with connective tissue dysplasia. The mean value of the rank index of pain in the main group is higher than in the comparison group. The emotional component prevailed in the inner picture of the perception of pain. Psycho-emotional status was distinguished by a high level of average score of reactive and personal anxiety. Summary. Systemic pathology associated with connective tissue dysplasia increases the clinical course of primary dysmenorrhea among adolescents, which gives grounds to differentiate the treatment and diagnostic algorith

Galectin-9 influences the Tim-3 molecule expression in natural killer different subpopulations

Galectin-9 is a b-galactoside binding lectin with expressed immunoregulatory activity. During pregnancy galectin-9 is produced by trophoblast cells and regulates the function of natural killer (NK) cells at the maternal-fetal interface via binding to Tim-3 (T-cell Ig and mucin domain-containing protein 3) molecules. Natural killer (NK) lymphocytes belong to the innate lymphoid cells, which have a cytotoxic effect on target cells and are capable of producing a large number of regulatory factors (cytokines, chemokines). Decidual NK have a tolerant phenotype and play a leading role in the regulation of invasive trophoblast growth and provide peripheral immune tolerance in the area of uteroplacental contact. Peripheral NK cells express Tim-3 molecules. Galectin-9 concentration is increased in peripheral blood during physiologic pregnancy. At pregnancy phenotype and functions of peripheral NK cells are changed to maintain the maternal–fetal immune tolerance. Peripheral NK cells migrate to the maternal-fetal interface and are transformed into a decidual NK-like phenotype cells. Galectin-9 concentration is decreased in women with a  complicated  pregnancy and miscarriage. However the galectin-9 effects on different NK cell subpopulations of peripheral blood are not investigated. Therefore, we studied the galectin-9 influence on phenotype transformation and Tim-3 expression of NK cells isolated from peripheral blood of healthy non-pregnant fertile women. CD56+NK cells were obtained by immunomagnetic separation and cultivated in vitro during 72 hours with cytokines (IL-2 and IL-15). Galectin-9 (5 ng/mL) and anti-Tim-3 (10 mg) antibodies were added to the NK cultures. Galectin-9 concentration is corresponded to its level during first trimester of physiologic pregnancy. The number of regulatory NK (CD16-CD56bright), cytotoxic NK (CD16+CD56dim/-) cells and Tim-3 expression on different NK subpopulations were assessed by flow cytometry. It was found that Tim-3 was expressed on all subpopulations of peripheral blood NK cells (CD16-CD56brightNK, CD16+CD56dimNK, CD16+CD56-NK). Incubation with galectin-9 increased the expression of Tim-3 on regulatory CD16-CD56brightNK cells and did not change on cytotoxic CD16+CD56dim/-NK cells. Galectin-9 reduced the percentage of cytotoxic CD16+CD56dimNK in culture, but did not influence the number of regulatory CD16-CD56bright NK and cytotoxic CD16+CD56-NK cells. Thus, galectin-9 regulates Tim-3 molecule expression and NK cell subpopulation distributions in vitro culture
