Efficacy of application of the luteotropic drug for the prevention of intrauterine growth restriction in dairy cows

Purpose: studying the effectiveness of the use of luteotropic action for preventing embryonic development disorders.Materials and methods. The research object is lactating animals in 60-75 days after a selection that manifests sex cyclicity and separated into 4 groups. The first group (n = 11) – in the insemination of parenterally injected the preparation of tautin at a dose of 5 ml. The second group (n = 11) – tautin was administered at a dose of 10 ml on the same time as cows of the first group. The third group (n = 12) – tautin injected 10 ml twice: during seeding and on the 14th day after seeding. The fourth group (n = 12) – was injected with saline per day of seeding and on the 14th day at a dose of 10 ml (negative control). Conducted a transrectal and ultrasound study at the end of the 1st and 2nd month of gestation, in which the size of the yellow body of pregnancy, embryo and the fetus was taken into account. Upon completion of pregnancy, all animals are taken into account: the nature of the flow of labor (physiological flow, objectiveness, fulbirth, detention, postpartum), postpartum period (physiological flow, submissiveness of the uterus, endometritis), the state of newborn calves (gender of the fetus, the time of manifestation of confident poses of standing, sucking reflex, body mass).Results. It has been established that the twofold administration of the tautin during seeding and on the 14th day after a dose of 10,0 ml is accompanied by an increase in fertilization by 19,7-28,8%, a decrease in the delay syndrome of the fetus development of 1,4-4,0 times, Absence of embryonic mortality. The use of the drug Tautin twice in a dose of 10,0 ml is accompanied by an increase in the size of the yellow body of pregnancy in 1,43-2,15 times, in comparison with other modes of its use, cockerel-dump-sized – by 12,9-37,6% and diameter Cases – by 10,1-46,6%. The use of a luteotropic drug is accompanied by a decrease in the incidence of cows to the detention of the last 1,8 times, the submissive of the uterus – 1,8 times, endometritis – by 2,7 times, the time of manifestation of confident posture of the standing of newborns of newborn calves – by 15,6 minutes, a sucking reflex – on 16,5 min and diarrheal syndrome – 2,7 times.Conclusion. The scientific novelty of research lies in the fact that new knowledge is obtained on the effectiveness of the use of the drug of luteotropic action, created using the technology of recombinant proteins, for the prevention of violations of embryonic development in cows.

Influence of the diet's structure on the occurrence of the main gynecological pathologies in the sakhalin population of holstein cows

It was established that the level of metabolic energy and the content of raw fiber in diets significantly affects the milk productivity and the occurrence of reproductive pathologies of cows. With a high level of crude fiber and a lack of metabolic energy in the diet, 12.5 % of cows in the herd were diagnosed with persistent ovarian yellow body. Yellow bodies in the ovaries, as shown by surveys, were most often found 25-30 days after delivery or within the same period of time after infertile insemination, as well as in more distant terms. 23 % of sick cows have a diagnosis "ovarian hypofunction", with impaired growth, development, maturation and timely bursting of the follicles. In some cases, ovarian hypofunction occurred as a result of abnormal labor, untimely start-up and physiological old age of cows. In addition to ovarian pathology, cases of pathological processes in the uterus also led to infertility. Endometritis, as a rule, occurred with inflammation of the uterine mucosa (endometrium). This pathology usually occurred in cases of infection, injuries of the uterine mucosa during pathological childbirth, and retention of the afterbirth. With a low level of raw fiber in the diet and a high content of metabolic energy, the most common cows' pathologies were gynecological diseases in 28 heads (23.3 %). Pathological processes in the ovaries with a high level of metabolic energy in the diet almost completely disappear. Most often, endometritis was diagnosed in sick animals - 98.4 %, associated with infection of the genitals and birth injuries. Studies have shown that blood metabolites, body reserves, and the effectiveness of feeding dairy cows depend on the pH of the environment that occurs when feeding different types of diets. One of the conditions for active fermentation of the substrate is the optimal amount of raw fiber. Pathological processes in the ovaries with a high level of metabolic energy in the diet almost completely disappear.

Body coloration as a dynamic signal during intrasexual communication in a cichlid fish

Background Intrasexual competition over access to resources can lead to aggression between individuals. Because overt aggression, i.e. fights, can be costly for contestants, the communication of aggressive motivation prior to engagement in a physical fight is often mediated by conventional signals. Animals of various taxa, including fishes, display visual signals such as body coloration that can dynamically be adjusted depending on the individual’s motivation. Male individuals of the West African cichlid Pelvicachromis taeniatus express a yellow body coloration displayed during courtship but also in an intrasexual competition context. Results Within-individual variation in male yellow body coloration, as quantified with standardized digital photography and representation in a CIELab color space, was examined in a mating context by exposing males to a female and in a competitive intrasexual context, i.e. in a dyadic contest. Additionally, spectrometric reflectance measurements were taken to obtain color representations in a physiological color space based on spectral sensitivities of our model species. Exposure to females did not significantly affect male color expression. However, analysis of body coloration revealed a change in within-individual color intensity and colored area after interaction with a male competitor. In dominant males, extension of coloration was positively correlated with restrained aggression, i.e. displays, which in turn explained dominance established between the two contestants. Conclusion Body coloration in male P. taeniatus is a dynamic signal that is used in concert with display behavior in communication during intrasexual competition.

A new species of Trimma (Pisces: Gobiidae) from the northern Palauan Islands, western Pacific Ocean

A new species of Trimma is described from the northern Palaun islands. Trimma kalum n. sp. lacks scales on the cheeks, opercle and nape, has an elongate second spine of the first dorsal fin, reaching posteriorly to the base of the 2nd–10th ray of the second dorsal fin when adpressed, 17–18 pectoral-fin rays with 12–13 branched rays in the middle of the fin, a single dichotomous branch point in the 5th pelvic-fin ray, which is 51–75% the length of the 4th ray, a very well developed dermal crest in the midline between the base of the first dorsal spine and the posterior interorbital region, a U-shaped interorbital trench with no fleshy median ridge, a poorly developed postorbital trench ending between the 4th to 5th papillae in row p, which has 6 papillae in total, and there are 5 papillae in row c beneath the eye. When live and freshly collected, the species is very similar in appearance to T. sheppardi, with an overall yellow body, three yellow bars across the cheek, and a double dark spot above the posterior portion of the opercle.

ebony affects pigmentation divergence and cuticular hydrocarbons in Drosophila americana and D. novamexicana

1AbstractDrosophila pigmentation has been a fruitful model system for understanding the genetic and developmental mechanisms underlying phenotypic evolution. For example, prior work has shown that divergence of the tan gene contributes to pigmentation differences between two members of the virilis group: Drosophila novamexicana, which has a light yellow body color, and D. americana, which has a dark brown body color. Quantitative trait locus (QTL) mapping and expression analysis has suggested that divergence of the ebony gene might also contribute to pigmentation differences between these two species. Here, we directly test this hypothesis by using CRISPR/Cas9 genome editing to generate ebony null mutants in D. americana and D. novamexicana and then using reciprocal hemizygosity testing to compare the effects of each species’ ebony allele on pigmentation. We find that divergence of ebony does indeed contribute to the pigmentation divergence between species, with effects on both the overall body color as well as a difference in pigmentation along the dorsal abdominal midline. Motivated by recent work in D. melanogaster, we also used the ebony null mutants to test for effects of ebony on cuticular hydrocarbon (CHC) profiles. We found that ebony affects CHC abundance in both species, but does not contribute to qualitative differences in the CHC profiles between these two species. Additional transgenic resources for working with D. americana and D. novamexicana, such as white mutants of both species and yellow mutants in D. novamexicana, were generated in the course of this work and are also described. Taken together, this study advances our understanding of loci contributing to phenotypic divergence and illustrates how the latest genome editing tools can be used for functional testing in non-model species.

ANATOMIC-FUNCTIONAL STATE OF PELVIC ORGANS IN WOMEN WITH INFERTILITY AND OVARICOVARICOCELE

Introduction. High informativeness and accessibility of ultrasound examination in infertile patients provides for the exclusion or confirmation of morphological changes in genitals, the degree of damage to the organ and the involvement structures, in particular, varicose veins of the gonadal veins, which can be explained by the emergence of ovarian dysfunction. In addition, the polymorphism of semiotics of echographic signs of pathological changes in pelvic organs in the examined patients confirms the complexity of determining the main and concomitant etiological factors of the emergence of functional infertility in women, the development of disorders of reproductive function and causes the need to involve other methods. The aim of the work was to study the anatomical and functional characteristics of the pelvic organs by ultrasound, medical diagnostic laparoscopy and hysteroscopy to determine the degree of morphological changes of the genitals in women with infertility and ovaricovaricocele. Materials and methods. To solve the goals and objectives, 117 pregnant women of reproductive age (21-44 years old) with functional infertility were prospectively examined and divided into 2 groups for the comparative analysis: the main group was 62 women with infertility and varicose veins in the ovaries; a comparison group was 55 women with infertility without varicose veins. The study of the anatomical and functional state of the uterus, ovaries and fallopian tubes in women of the studied groups was performed by standard ultrasound examination on the PHILIPS ATL-HDI 4000, PHILIPS HD 11-XE with the analysis of folliculogenesis. Laparoscopic intervention was performed by the patients of the main group on the apparatus "Karl Storz" (Germany) in the first phase of the menstrual cycle. Diagnostic hysteroscopy in order to clarify the state of the uterus and endometrium was performed simultaneously with laparoscopy in the 1st or 2nd phase of the menstrual cycle using the equipment "Karl Storz" (Germany).Results. In women of the main group with a combination of functional infertility and ovaricoaricocele, there is a statistically significant increase in the percentage of incorrect position of the uterus - 36 (58.1%) in normal form and size of the uterus, both in the main group of women and in the comparison group - 53 (85,5%) and 48 (87.3%) cases respectively. Analyzing the indicators of ovarian size and the number of antral follicles, a statistically significant difference was found in the direction of its reduction in women with functional infertility and ovaricovaricocele women without varicose dilatation of ovarian veins - 4.1 ± 0.1 cm3 vs. 5.8 ± 1 , 4 cm3 and 3.9 ± 1.1 versus 5.6 ± 1.4, respectively, in two groups. In addition, there is a tendency to reduce the size of the ovary of the protradiental age in women of all the studied groups with statistically significant rates in the patients of the main group. Also, there is a difference in the right ovary volume relative to the left in women with infertility and ovaricovaricocele in the direction of decreasing the size of the latter, which may be due to the predominant localization of the enlarged gonadal vein, and this difference is statistically significant. In determining the functional state of the ovaries in the overwhelming number of women in all of the studied groups ovulation was noted, however, when studying the characteristics of the functional state of the yellow body according to echographic signs, decrease in the thickness of the endometrium in the middle of the luteal phase of the menstrual cycle in patients of the main group, as well as the absence in the overwhelming majority cases of its adequate secretory changes, which is statistically significant against the women of the comparison group. In patients, both the main group and the comparison groups, there is a decrease in the ratio of the volume of the yellow body and ovarian volume and the decrease in the thickness of the wall of the yellow body, respectively, against the control group women, which is an ultrasound sign of inferiority of the yellow body and lack of luteal phase of the menstrual cycle. In addition, women in the main group have a statistically significant reduction in the rates against the women in the comparison group. In women of the main group, a large percentage of varicose veins of the small pelvis are found in the absence of organic changes in the uterus and adnexies (73.3%) in the presence of infertility of obscure genesis.Conclusions. Ultrasound study in combination with color Doppler of patients with ovaricovaricocele is a highly informative method of research, because it allows to perform topical diagnosis, to determine the morphological character of the lesion, to differentiate the type of pathological process and to identify the concomitant pathology of the pelvic organs. The conducted study suggests that ovaricovaricocele should be considered not only as an accompanying symptomatic changes in diseases of the female genitals, but also as one of the causes of ovarian dysfunction with delay or termination of growth of the follicles, change in their size, degenerative-dystrophic changes in the ovaries, which leads to a violation hormonal homeostasis and manifested by reproductive disorders. In the perspective of further research it is necessary to consider a complex analysis of the morphological and functional characteristics of the internal genital organs, which will establish the presence of a certain functional and organic gynecological pathology and will enable to diagnose the initial and minimal course of the pathological process of the pelvic organs, finally verify the final diagnosis and appoint pathogenetic treatment.

The Multisystemic Effect of Oestradiol Variations

Ovarian hormones are: oestrogenic hormone, also known as follicular hormone or female sexual hormone or chemically oestradiol; yellow body hormone, progestin or, chemically, progesterone. Oestrogenic hormone is particularly involved in the first part of the oestrus period, and the yellow body hormone in the second part (pseudo-pregnancy) and in the gestation state; the third ovarian hormone, known as relaxin, was isolated from the yellow body. Oestrogens are responsible for the development of female secondary features. Together with progesterone it controls the most important female reproductive processes. The most biologically active of oestrogens is 17b-oestradiol. Oestradiol is produced by ovarian follicles, testicles, but also by some organs such as the liver, adrenal glands, mammary glands and the brain. Oestradiol activates two specific nuclear proteins, oestrogen receptors alpha (ER�) and oestrogen receptors beta (Er�). Oestrogen receptors alpha are predominant in the mammary gland, genital apparatus, bone, nervous and cardiovascular system. Oestrogen receptors beta are found in the uterus, monocytes, tissue macrophages, colon and lung epithelial cells, epithelial cells of the prostate. The main actions of oestradiol are: endometrial proliferation, effects on the vagina and the mammary gland; it also has a role in preventing osteoporosis and reducing cardiovascular risk. Oestradiol is primarily produced in the ovary (the follicle, yellow body), but small amounts are also formed in the testicles and the cortex of the adrenals. In pregnancy, oestrogen is mainly produced by the placenta. Approximately 98% of oestradiol is linked to sex hormone binding globulin (SHBG). The level of oestradiol increases throughout the follicular phase of the menstrual cycle in close dependence with the growth and development of the ovarian follicle. For the determination of oestradiol, we conducted a study of 64 people, of which 47 women (73.43% and 17 men (26.57%). The presence of oestrogen receptors alpha indicates an increased risk of breast cancer. Breast cancer is hormone dependent, 74% of cases are oestrogen-positive receptors, and 30% of cases are progesterone-positive receptors. The main reason for the development of hyperplasia is the increase in oestrogen levels.

CASE OF POLYCARPOUS TUBAL ECTOPIC PREGNANCY

The case of multiple ectopic tubal pregnancy is presented in the 5–6 weeks term. An expanded right uterine tube containing two embryos was found. The amniotic partition was not visualized. The uterus is located typically, increased to 7–8 weeks of gestation, due to decidual reaction. The right ovary was identified in a typical place, the yellow body in its projection was not visualized. The left ovary was determined behind the uterus, in its projection the reminding yellow body was defined.

Detection of genetic polymorphism of ANGPTL4 and POMC gene and correlation with growth traits in Guanling cattle

In this study, the polymorphism of ANGPTL4 and POMCgene in 92 individuals of Guanling cattle was detected using DNA sequencing technology, and the correlation between polymorphic loci and growth traits of Guanling cattle was analyzed. Three mutation sites including 387 C > T, 418 C > T and 449 A > T were detected in ANGPTL4 gene. Five mutation sites including 138 C > T, 430 C > T, 644 C > T, 668C > T, and 693A >G were detected in POMC gene. The results showed that three polymorphic mutation sites of ANGPTL4 gene in the Hardy - Weinberg disequilibrium (HWE) (P Lass Than 0.05), POMC gene in 430 C > T mutation the mutation in HWE equilibrium (P > 0.05), multi peptide information content of ANGPTL4, POMC gene polymorphisms (PIC) showed moderate polymorphism. The correlation analysis results showed that the ANGPTL4 gene 418 C > T mutation genotypes and Guanling yellow body height, body length, chest circumference, abdominal circumference showed significant differences (P Lass Than 0.01), 449 A>T mutation geno types and Guanling yellow body height showed a significant difference (P Lass Than 0.05) and chest circumference, abdominal circumference showed significant differences (P Lass Than0.01). POMC gene 644 C > T and 668C > T mutation loci and body length of Guanling yellow cattle showed significant difference (P Lass Than 0.05).
