The hyperplastic processes of the endometrium can arise not only against the background of excessive influence of estrogen, but also against the background of epigenetic damages that affect apoptosis, cell proliferation, differentiation, and adhesion, and DNA reparation. The aim of our study was to investigate and analyze the status of methylation of the promoter of SFRP2 gene in patients with hyperplastic processes of the endometrium. Materials and Methods: The study groups were the following: I — patients with endometrial hyperplasia (EH, n = 9); II — patients with endometrial intraepithelial neoplasia (EIN, n = 10), III — control groups: 1) with endometrial cancer (EC, n = 4), and 2) healthy women (n = 4). Determination of promoter methylation of SFRP2 gene was carried out by the semiquantitative method of methylation-specific PCR assay. Results: The maximum level of methylation of SFRP2 gene promoter had been revealed in patients with EC — 42.80 ± 3.55% (р < 0.05). The patients of the I group had the lowest values of methylation of SFRP2 gene promoter — 10.66 ± 0.85%, while in patients of the II group this indicator was higher — 20.60 ± 0.95% (р < 0.05). In healthy women of the control group, methylation of SFRP2 gene promoter was detected in none of the samples. Conclusion: The content of the methylated SFRP2 gene in endometrial tissue of patients with hyperplastic processes higher than 20–25% allows relate these women to the risk group of EC development and dictates the need of intensive observation of such patients.

AimsGene promoter hypermethylation is recognised as an essential early step in carcinogenesis, indicating important application areas for DNA methylation analysis in early cancer detection. The current study was set out to assess the performance of CADM1, MAL and miR124-2 methylation analysis in cervical scrapes for detection of cervical and endometrial cancer.MethodsA series of cervical scrapes of women with cervical (n=79) or endometrial (n=21) cancer, cervical intraepithelial neoplasia grade 3 (CIN3) (n=16) or CIN2 (n=32), and women without evidence of CIN2 or worse (n=120) were assessed for methylation of CADM1, MAL and miR124-2. Methylation analysis was done by the PreCursor-M assay, a multiplex quantitative methylation-specific PCR.ResultsAll samples of women with cervical cancer (79/79, 100%), independent of the histotype, and 76% (16/21; 95% CI 58.0% to 94.4%) of women with endometrial cancer scored positive for DNA methylation for at least one of the three genes. In women without cancer, methylation frequencies increased significantly with severity of disease from 19.2% (23/120; 95% CI 12.1% to 26.2%) in women without CIN2 or worse to 37.5% (12/32; 95% CI 20.7% to 54.3%) and 68.8% (11/16; 95% CI 46.0% to 91.5%) in women with CIN2 and CIN3, respectively. Overall methylation positivity and the number of methylated genes increased proportionally to the lesion severity.ConclusionsDNA methylation analysis of CADM1, MAL and miR124-2 in cervical scrapes consistently detects cervical cancer and the majority of CIN3 lesions, and has the capacity to broaden its use on cervical scrapes through the detection of a substantial subset of endometrial carcinomas.

Objective: to assess molecular profiles of endometrial hyperplasia and endometrial intraepithelial neoplasia.Materials and methods. We conducted a retrospective study that included 77 patients with a morphologically verified hyperplastic process in the endometrium. Of them, 34 patients had endometrial hyperplasia and 33 patients had endometrial intraepithelial neoplasia. The control group comprised 30 women with no endometrial disorders according to the results of histological examination.Results. Patients with endometrial intraepithelial neoplasia are at high risk of developing cancer. High angiogenic activity, pronounced vascularization, and endometrial hypoxia are believed to be important risk factors contributing to tumor proliferation and transformation. The expression of inhibitors of apoptosis, such as survivin and Bcl-2, is usually increased in atypical cells, which may indicate their involvement in malignant transformation of cells and tumor invasive growth.Conclusion. Our findings confirm the important role of survivin and Bcl-2 in hyperplastic processes in the endometrium.

Background: Arthroscopy and splint bone removal are the common orthopedic procedures in horses. Estimation of the dynamics of acute phase proteins in postoperative monitoring seems to be interesting diagnostic approach. The aim of the study was to investigate changes in the concentrations of plasma inflammatory markers—fibrinogen, haptoglobin, and protease inhibitors—following orthopedic surgery in horses. The study involved 114 horses, divided into two study groups undergoing: arthroscopy (41 horses) and splint bone removal (13 horses). The control group consisted of 60 healthy horses. The blood was collected before the surgery and 24, 48, 72 h, 5, 7, 10, 14 and 28 days after the surgery. Plasma fibrinogen, serum haptoglobin and proteinase inhibitors were measured. Results: In non-complicated cases of arthroscopy and splint bone removal, fibrinogen and haptoglobin increased stepwise from 24 h, achieved the maximum level at 72 h and returned to preoperative levels after 10–14 days. In one complicated case after arthroscopy surgery the marked increase in fibrinogen and haptoglobin concentrations was observed 24 h earlier than standard parameters of inflammation Conclusion: The study shows the evolution of APPs after arthroscopy and splint bone removal in 28 days postsurgery period and in the case of one complicated case of arthroscopy.

Abstract. The aim of the work is to develop forensic criteria for differential diagnosis of traumatic hemorrhages (HTG), ischemic stroke (IS), and hemorrhages of nontraumatic genesis (HNG) formation by 3D Mueller-matrix microscopy of layers of azimuthal-invariant Mueller-matrix images of circular birefringence of histological sections of the brain. Material and methods. Native sections of brain taken from 110 corpses were used for the study in the case of: death from coronary heart disease - 20 (18.1%) native sections (group 1 - control); HTG - 30 (27.3%) sections (group 2), IIB - 30 (27.3%) sections (group 3), HNG - 30 (27.3%) sections (group 4). Measurement of the values of the distribution of coordinate parameters of polarization at the points of microscopic images was performed at the location of the standard Stokes polarimeter. Results. It is found that for each of the phase cross-sections of the field, the volume of distributions of complex amplitudes of sensitivity, specificity and balanced accuracy of statistical analysis of coordinate distributions of Mueller-matrix invariants of circular dichroism have maximum values for small phase shifts corresponding to their level. The maximum level of balanced accuracy of intergroup differentiation was revealed by calculating statistical moments of the 3rd and 4th order, which characterize the asymmetry and excess distributions of the Mueller-matrix invariants values of circular dichroism of histological sections of brain substance. Conclusions. Excellent balanced accuracy (95% - 96%) of differential diagnosis was achieved between the control group and all study groups, good accuracy (92% - 93%) between ischemic stroke and traumatic hemorrhage and satisfactory accuracy (85% - 86%) between traumatic and hemorrhagic strokes genesis.

In the complex mechanism that controls the onset of labor, there are many factors, among which an important role belongs to the cervix, so to reduce the risk and development of obstetric and perinatal complications, the problems of timely diagnosis and adequate treatment of cervical diseases are still relevant today.The objective: еvaluate the features of childbirth and the postpartum period in women who have undergone destructive treatments for cervical pathology.Materials and methods. All examined women (n=201) after destructive methods of treatment of the cervix for dysplasia of I–III degree (electroconization, cryodestruction, laser vaporization or radiowave excision) were divided into 3 groups: 1 group (retrospective, n=114) – patients, in which features of childbirth and the postpartum period were studied anamnestically; 2 group (prospective, n=57) – women who were included in the study immediately after surgery; 3 group (control, n=30) – almost healthy women. Patients in the comparative groups were comparable in age (mean age 25,7±4.4 years) and the course of the pathological process in the cervix.Results. During the 5 years of the study, the peculiarities of the course of childbirth, the condition of newborns and the postpartum period in patients after surgery were studied. In the 1st group of subjects 114 pregnancies were registered, of which 97 ended in childbirth: naturally – in 66 women (57,9%), cesarean section – in 31 (27,2%). The main complications in childbirth were weakness of labor (44 patients – 45,4%), fetal hypoxia (41 patients – 42,3%), premature birth (36 patients – 37,1%).In the 2nd group of women 57 pregnancies were registered (50 births): naturally – in 7 patients (12,3%), cesarean section – in 43 women (75,4%). The most common complication in this group was placenta previa (6 cases – 12,0%).In the control group, 30 pregnancies (27 births) were registered: in 22 women (73,3%) by natural means, in 5 (16,7%) – by cesarean section. The most common complications of childbirth in this group were weakness of labor (4 cases – 14,8%), bleeding in the postpartum period (3 patients – 11,1%) and hypoxia of the fetus (3 cases – 11,1%).The high percentage of women in group 1 who were diagnosed with ruptures of the cervix of varying severity (the largest in patients after electroconization), in groups 2 and 3, isolated cases were noted.In all three groups, more than half of the newborns had normal body weight (3000 to 4000 g) and a high Apgar score (8 to 9 points).Conclusion. In the analysis of childbirth in women of the three study groups, it was found that compared with somatically healthy women (group 3) in patients after destructive treatment of cervical pathology (groups 1 and 2) there is a decrease in the proportion of births through natural routes (73,3%, 57,9% and 12,3%, respectively) and an increase in the proportion of births by cesarean section (16,7%, 27,2% and 75,4%). The highest percentage of surgical interventions was recorded in the first two groups in women after amputation and conization of the cervix, the lowest – in patients after laser vaporization and radiosurgical excision. Therefore, these methods of destruction of the cervix are the least traumatic, can cure the underlying disease and preserve reproductive function.

Neglected pain in neonates leads to various ill effects and it can be prevented by using simple and safe non-pharmacological pain relieving measures. Pharmacologic agents are not recommended in neonates for acute pain due toinvasive procedures however, administration of 24% oralsucrose solutionis found to be effective. The objective of this study was to assess the efficacy of 24%oral sucrose in combination with Facilitated tucking during BCG Vaccination through intradermalroute in term neonates which is not done elsewhere. Fifty five healthy term neonates who fulfilled the inclusion criteria such as gestational age above 37 weeks, within 24 hoursof birth age, and neonates delivered only through spontaneous vaginal delivery were included in the study. The study intervention consists of administration of 2 ml of oral 24% sucrose 2 minutes before BCG Vaccination through intradermal route and Facilitated tuckingat the time of vaccination. The primary outcome measure of cumulative NIPS score at 0, 3,5 minuteswas not significant in both the study groups. Whereas there was significant reduction in the level of pain and mean cry time in the neonates of sucrose group. Heart rateand oxygen saturation after intradermal injection also showed significant (p less than 0.001) differenceamong the neonates, who received 24% of oral sucroseand Facilitated tucking than for neonates of control group. Thus oral (24%)sucrose solution given 2 minutes before injection was effective in reducing level of neonatal pain following Intradermal Vaccination. It is a simple, safe and fast acting analgesic and should be considered for minor invasive procedures in term neonates which last for 5-7minutes.

This is an experimental trial to prepare a vaccine from gamma-irradiated Giardia lamblia which is evaluated in experimental animals. The study was conducted from December 2015 to April 2016. The field survey of the parasite was conducted from those patients attending the laboratories of the Alawi Children's Hospital in Rusafa and the Al-Yarmouk Teaching Hospital in Karkh, through which 1250 stool samples of different age groups were examined. Five groups of mice were used in the study; the first was injected with normal saline and considered as a negative control group, the second was injected with cystic form of non-irradiated Giardia lamblia and considered as a positive control group, whereas the other three groups were injected with gamma irradiated Giardia lamblia at three different doses 10, 15 and 25 rad respectively. Giardia lamblia was primarily cultivated in liver infusion agar for ten days to obtain the active phase. On the sixth day, the cystic phase was purified and standardized to be used in the infection of mice with or without the exposure of gamma rays. Mice showed high sensitivity to parasitic infestation, in the gamma non-irradiated and the irradiated with gamma 10 rad, and 15 rad irradiated groups which was 100%. The results expressed an excystation process of the depleted phases and the release of the feeder phases. The results of the three irradiated groups consisted of histopathological changes of the small, and the rectum by dissection after two weeks of infection, with intestine amputation lesions, as well as ulceration and inflammation of the inflammatory cells represented in small numbers of neutrophil, lymphocytes, and eosinophils. The presence of ulceration and fall of epithelial cells in the intestinal cavity has been shown, and different forms of the parasite have been observed. Mice which was injected with irradiated G lamblia at high dose (25 rad), not show and sensitivity to the challenge infection and no excystation of thy parasite had been done. After 2 wreaks, a comparison was achieved between all study groups in which no histopathological changes were noticed in the mice irradiated with dose of25 rad. After another two weeks, a challenge dose was given (un-attenuated G lamblia) and mice were dissected after another two weeks, no changes on the level of histopathology of intestinal tissue were noticed the results suggested that mice acquire an immunity against the parasite infection.

Перспективным в изучении биомаркеров мигрени может быть многолокусный анализ, в частности, анализ частот сочетанных генотипов. Цель исследования - поиск составных генетических биомаркеров индивидуальной предрасположенности к мигрени, полученных на основе полиморфизмов генов, уже показавших статистическую значимость при однолокусном ассоциативном анализе. Методика. Обследовано 155 пациентов с мигренью (104 пациента с эпизодической мигренью, 51 - с хронической мигренью), наблюдавшихся в Университетской клинике головной боли (Москва). Все пациенты - представители белой расы, жители Московского региона. Возраст пациентов - 30-50 лет. Контроль составили 365 необследованных лиц (популяционный контроль). Выявление исследуемых 22 генов (всего 31 SNP) осуществляли методом ПЦР, ПЦР-ПДРФ, аллель-специфичной ПЦР и ПЦР в реальном времени. Выявление ассоциированных с мигренью сочетанных генотипов проводили с использованием программы анализа полигенных данных APSampler v3.6. Результаты. Выявлено 8 сочетанных генотипов с высокой статистически значимой ассоциацией с мигренью (ОШ>20,0). В состав сочетанных генотипов вошли гены: CCKAR, CCKBR, COMT, MTHFR, MTR, MTRR. Так же выявлено 4 защитных сочетанных генотипа (ОШ<0,02), основным в которых является ген MAOA. Заключение. Полученные данные об ассоциированных с мигренью сочетанных генотипах указывают на значимую роль в патогенезе заболевания 2 биохимических систем: 1) холецистокининергической системы, регулирующей выброс и обратный захват дофамина, и 2) фолатного цикла, в ходе работы которого гомоцистеин метаболизируется в метионин. Результаты, полученные в данном исследовании, позволяют говорить о защитной роли аллеля VNT:R4 гена MAOA.Multilocus analysis, specifically, analysis of combined genotype frequencies may be promising in studying migraine biomarkers. The aim of the study was to search for composite genetic biomarkers, which would predict individual predisposition to migraine, obtained on the basis of gene polymorphisms that have already shown a statistical significance in a single-locus associative analysis. Methods. 155 patients with migraine aging 41.7 ± 12.5 who had been followed up at the University Clinic of Headache, Moscow, were evaluated (104 patients with episodic migraine and 51 with chronic migraine). All patients were white and residents of the Moscow region. The control group included 365 unexamined individuals (population control). Identification of The 22 genes under study (total, 31 SNPs) were identified by PCR, PCR-RFLP, allele-specific PCR, and real-time PCR. Combined genotypes associated with migraine were identified using the APSampler v3.6 software for polygenic data analysis. Results. Eight combined genotypes were identified with a highly significant association with migraine (OR> 20.0). The combined genotypes included the CCKAR, CCKBR, COMT, MTHFR, MTR, and MTRR genes. Four protective combined genotypes were also identified (OS <0.02) with the MAOA gene as the major one. Conclusion. Our data on migraine-associated combined genotypes indicate a significant role in the migraine pathogenesis of two biochemical systems, i) the cholecystokininergic system that regulates the release and reuptake of dopamine, and ii) the folate cycle, where homocysteine is metabolized to methionine. The results obtained in this study suggest a protective role of the VNT: R4 allele of the MAOA gene.
