EMBRYO GLUE AND CLINICAL PREGNANCY RATES IN ICSI EMBRYO TRANSFER CYCLES: A PROSPECTIVE STUDY

Purpose: One of the reasons for failed implantation after transferring good quality embryos in an intracytoplasmic sperm injection cycle is the failure of creation a viscid layer between the embryo and the endometrium. Many modifications have been made in embryo transfer medium to improve implantation and increase pregnancy rates such as adding albumin as a source of energy and adding hyaluronic acid in high concentrations such as in Embryo Glue medium: a human embryo transfer medium. To investigate whether the use of Embryo Glue had any effect on clinical pregnancy rates in intracytoplasmic sperm injection-fresh embryo transfer cycles. Methods: A prospective study included one hundred and twenty-eight infertile Iraqi women who were selected and subjected to a stimulation protocol in an intracytoplasmic sperm injection-fresh embryo transfer cycle. All patients were considered to be eligible for embryo transfer (no visible causes could prevent implantation) and only good quality embryos were transferred to them. Those women were divided randomly into two groups according to type of embryo transfer medium: group A: Embryo Glue medium. group B: Conventional medium. Then group A was subdivided according to age into: AI (34 women with age < 35 years and represented 50.7%) AII (33 women with age ≥ 35 years and represented 49.3%) While group B was subdivided into: BI (41women with age < 35 years and represented 67.3%) BII (20 women with age ≥ 35 years and represented 32.7%). Results: Although there was no significant difference between all groups in causes of infertility, the pregnancy rate was significantly higher in subgroup AII (18 pregnant from 33 women) while only 5 patients became pregnant from 20 patients in subgroup BII. In all women no more than four good quality embryos were transferred, and when total number of transferred embryos was significantly more in group B than group A (P=0.013), the significant increase in pregnancy rates was only observed in subgroup AII (P=0.048). Even though a highly significant difference in number of repeated implantation failure was in group A than group B (P=0.027), the pregnancy rates were significantly higher in group A (P=0.038). Conclusion: This study concluded that using Embryo Glue has a beneficial effect on old women and increase pregnancy rates, also it has a positive effect on pregnancy rates in repeated implantation failure and increases pregnancy rates even if the women is old.

Penggunaan Metode K-Means Cluster Untuk Mengklasifikasikan Kemampuan 4C Mahasiswa

The K-means method is a non-hierarchical belongs to an algorithmic technique for grouping items into K clusters by minimizing the SS sum of square (SS) distance to the centroid cluster. In the K-means method, the number of clusters can be determined by the researchers themselves. The K-means method can be applied to all fields, including education. In facing the 21st century, many students must equip themselves with many abilities, including critical thinking, collaboration, communication, and creativity and innovation, referred to as 4C abilities. This study aims to apply the K-means method to classify students' 4C abilities. The population in this study were students of the English Language State Institute of Islamic Studies Ponorogo class of 2017 and class of 2018. The sampling technique was carried out using the stratified random sampling method with a sample size of 71 divided into 30 students of the 2017 class and 41 students of the 2018 class. In identifying outliers, it is known that 16 students enter outlier detection not to be analyzed. The results of the classification using the K-means method showed that there were three groups with a composition of 20 students in the high group, 20 students in the medium group, and 15 students in the low group with an R2 value of 41.7%. Based on the test results of ANOVA, it is known that the three groups, based on their ability level, have differences. These results showed that each group formed had a noticeable difference, albeit with an R2 value that was not large.

Analisis Kemampuan Koneksi Matematika dalam Pemecahan Masalah Segitiga

This study aims to describe the mathematical connection ability of students in the high, medium, and low categories in solving math problems based on Polya's steps. This study used a qualitative approach with descriptive methods carried out in class VII SMP PGRI 06 Malang in the 2019/2020 academic year. The subjects of this study were 22 students of which three students' categorized into high mathematical connection ability, four students categorized into medium mathematical connection ability, and fifteen students categorized into low mathematical connection ability. The results of this study show that students with the high category of mathematical connection ability were able to connect between concepts by making concept maps and solving problems well. Students with the medium group of mathematical connection ability can connect between concept, but in the episode of implementing the plan and looking back at the results of their work did not do well. Students with the low category of mathematical connection ability cannot connect between concepts, so they cannot understand the problem well and cannot plan problem-solving.

Does personality matter when we are approaching the subjective perception of overtraining among adolescents?

This article deals with the issue of overtraining among elite adolescent athletes. The aim of our study was to examine the relationship between certain personality traits, as perfectionism, extraversion, neuroticism and other Big 5 traits and subjective perception of training load (which is one of the best indicator of overtraining syndrome). We also focused on the relationship between a perceived training difficulty and perceived training load too find out, if there is some kind of integral relationship. To collect data we used a questionnaire, which were given to adolescent elite athletes playing team sports in a mid-season period. The results show significant relationship between perceived training load and overall perfectionism (r=0.189, p<0.001), extraversion (r=-0.241, p<0.001), neuroticism (r=0.343, p<0.001) and consciousness (r=-0.287, p<0.001). After the closer examination we found an interesting relation between single dimension of perfectionism and perceived training load, suggesting the contribution of maladaptive perfectionism on development of overtraining syndrome. Besides that, we differentiated athletes into two groups, according to the level of perceived training difficulty. Those, who perceived training as difficult to exhausting (M=2,19, SD=0.50) were significantly higher than low to medium group (M=1.99, SD=0.47) in the perceived training load t(178)=-0.894, p=0.007. Those results extend our knowledge of overtraining topic and can be used in coaching practice to help identify athletes with higher risk of overtraining, or even prevent these states among young athletes before they occur. Hereby results suggest the importance of psychological aspects in sport preparation.

ISSR polymorphism of laying hens of broiler parental stock distinguished by rates of growth and productivity indicators

Searching for biomarkers of high productivity in chickens is currently one of the relevant tasks facing poultry farming. Thus, the research was aimed at studying genetic traits of laying hens. The hens belonged to parental stock of the «Arbor Acres Plus» hybrid cross and varied according to the productivity abilities. The study was carried out in 2018-2019 at the PRODO Tyumen Broiler factory located in Tyumen, Tyumen region on three groups of chickens numbering from 6000 to 6085 bird units. Raising and evaluation of laying hens were carried out in accordance with the «Arbor Acres Plus» guidelines and standards for breeding of the parental generation and the regulations for the technology of the parent stoсk management and bird weighing which were developed on the basis of those guidelines and standards and adopted at the factory. The practice of raising the «Arbor Acres Plus» hybrid cross revealed a distinct differentiation of laying hens by body weight during the growth period. There were distinguished fast-growing «large» individuals, «small» individuals and «medium» individuals occupying an intermediate position. At the beginning of the experiment, during the 18th week of age the average mass of «small» chickens was 106 g less than that of chickens from the «medium» group. The average mass of chickens from the «medium» group was 139 g less than the indications in the «large» group, and the differences between the «large» and the «small» hens amounted to 245 g. Such differences remained until the 35th week, and then they leveled out substantially. The differences between groups of chickens were observed also in egg production rates, which decreased with increasing the age of laying hens (by 31-33 weeks). The amount of eggs per layer per week averaged out at 71.1 % for “small” hens, 72.8 % for the «medium», and 74.4 % for the «large» ones. To assess the genetic polymorphism of chickens the ISSR-PCR method was applied. Seven primers were used to study the genetic polymorphism of laying hens: (AG)8G, (AG)8T, (CA)8G, (GT)8C, (AC)8T, (TC)8C, (TG)8A. The experimental groups of laying hens differed both in the frequencies of ISSR bands and in the average indicators of polymorphism. Higher parameters of the proportion of polymorphic bands (P), genetic diversity (h), apparent (ne) and effective number of alleles (na) were observed in the group of «large» laying hens, while the «medium» and «small» groups had lower rates and did not significantly differ in the level of polymorphism among themselves. Higher rates of ISSR polymorphism observed in the group of fast-growing («large») laying hens could be a marker of a higher level of genetic diversity in this group compared to chickens from the other two groups. The conducted studies showed that ISSR markers can be recommended as a simple tool for monitoring the genetic diversity of stocks of laying hens.

Economic analysis of onion seed production in Washim district of Vidarbha region

The present study is undertaken to study the economics analysis of onion seed production in washim district of Vidarbha.The study was based on primary data. Primary data of 90 farmers pertaining to the year 2018-2019 were collected from three villages and functionaries involved in onion seed procurement chain producer, seed company, retailer were selected for collecting information. The onion seed production is taken on small scale but it contributes sizable share in total earning of the cultivator. However, yield and profit from onion seed cultivation is uncertain because it is very sensitive, it require special attention. To study the economics of onion seed production, the standard cost concepts were used. In estimation of cost of cultivation, seed, rental value of land, human labour and interest on fixed capital were the major cost items.The gross cropped area was highest in large group i.e. 8.28 hectare followed by medium 5.27 ha and small group 2.93. The cropping pattern of onion seed was dominated by soybean, cotton and tur in Kharif season whereas gram and wheat was Rabi season. In Rabi season the contribution of area under onion seed was 12.62, 12.52 and 12.31 per cent by small, medium and large farmers. Per hectare total cost of cultivation of onion seed was highest in the medium group i.e. Rs. 167967.3 per hectare followed by large group Rs. 166102.74 and small group Rs.165161.53.The benefit cost ratio of onion seed at cost ‘C3’ was 1.70 in small group, 1.76 in medium group and 1.78 in large group.

Ratio of Baseline Monocyte Counts to Apolipoprotein A1 is Associated with Long-Term Mortality in Patients with Coronary Artery Disease After Percutaneous Coronary Intervention

Background: The relationship between the ratio of monocytes to apolipoprotein A1 (MAR) and the long-term prognosis of patients with coronary artery disease (CAD) after PCI has not been investigated. Methods: A total of 5678 patients with CAD after PCI were recruited for the present study from the First Affiliated Hospital of Xinjiang Medical University. The patients were divided into 3 groups according to the MAR tertiles: lower group (MAR<0.34, n=1881), medium group (0.34≤MAR<0.50, n=1859), and higher group (MAR≥0.50, n=1938). The primary endpoint was long-term mortality, including all-cause death (ACM) and cardiac death (CM). The mean follow-up time was 35.9 ± 22.6 months. Results: There were 78 (4.1%) deaths in the lower group, 90 (4.8%) deaths in the medium group, and 125 (6.4%) deaths in the higher group. The difference was significant (P=0.004). We also found significant differences among these three groups in the incidence of CM (P=0.012), MACE (P=0.008), and MACCE (P=0.012). Using 0.535 as an optimal cutoff value, we found that patients with MARs ≥0.535 had 40.5% and 39.9% increased risks of ACM and CM, respectively, compared to patients with an MAR<0.535. The differences remained significant after adjustment for confounders (ACM, HR=1.447, 95%CI: 1.139-1.838, P=0.003; CM, HR=1.424, 95%CI: 1.089-1.862, P=0.010). Conclusion: This study demonstrated that the baseline MAR was an independent predictor of long-term mortality in CAD patients who underwent PCI.
