The aim of this study was to find useful the serological markers for missed miscarriage (MM) in order to predict the outcome of pregnancy. The study included 141 pregnant women aged between 18 and 45 years at gestational age under 11 weeks. All women were divided into 3 groups. Group 1 included 68 women with MM; Group 2 included 43 women with spontaneous miscarriage; Group 3 included 30 pregnant women without pathology. Proteomic analysis of the blood serum was performed using liquid chromatography-mass spectrometry. The results of our study show that immunoglobulin kappa variable 3-15 (KV315) can be considered as the most promising serologic marker for MM in early gestation. The potential role of KV315 as the serological marker is very important for predicting the course of pregnancy.

Aim. Study of somatic and obstetric and gynecologic morbidity of women of the Kyrgyz Republic after Cesarean section. Methods. Retrospective cohort study was conducted in 2016 in Kyrgyz state medical institute of retraining and advanced training. Three regions of the Kyrgyz Republic were selected: Bishkek, Jalal-Abad and Issyk-Kul regions. 908 pregnant women after abdominal delivery were chosen as the subject of the study and divided into three groups: group 1 (Bishkek) - 305 pregnant women, group 2 (Jalal-Abad region) - 300 females, group 3 (Issyk-Kul region) - 303 females. The age was 15 to 49 years. The incidence of gynecologic and extragenital pathology and complications during previous pregnancies were studied. Results. Gynecologic pathology in past medical history was revealed in 15.8% of females, while women from group 1 are statistically significantly more likely to have gynecologic diseases than women from group 3. Females from group 2 had gynecologic pathology more rarely. In the structure of gynecologic incidence, sexually transmitted infections take the first place, cervical ectopy takes the second place and uterine fibroids - the third place. Extragenital pathology was detected in 38.2% of pregnant women. In its structure the first ranked place is taken by urinary tract diseases (12.3%), the second one - by infectious and parasitic diseases (11.6%), and the third place - by cardiovascular diseases (3.2%). Pathological course of pregnancy was also more frequent in group 1 than in group 2; there was no significant difference with group 3. Spontaneous abortion interrupted previous pregnancy in 19.8% of women, 5% had premature births, significantly more frequently in group 1, as well as preeclampsia. Conclusion. The most unfavorable region is the city of Bishkek, female residents of Jalal-Abad region are less susceptible to diseases; in general, gynecologic pathology was revealed in 15.8% of females, extragenital pathology - in 38.2% of pregnant women; pathological course of pregnancy was statistically more frequent in group 1 than in group 2, without significant difference with group 3.

The study was done to determine iron status, haemoglobin and protein levels of pregnant women in owerri metropolis. A total of 100 pregnant women were recruited for this study. The mean Hb levels in group 1, group 2, and group 3· were 12.00±1.68g/dl, 10.06±1.J4g/dl and 10.96±1.19g/dl respectively. The mean Serum ferritin level of group 1 was 67.00±88.38ng/ml, group 2, 52.48±52.47ng/ml and group 3, 51.26±48.70ng/ml. The mean Serum iron in group 1, 2 and 3 were 46.72±16.41 g/dl, 79.59±63.24 g/dl and 83.35±53.04 g/dl respectively. In group 1, 2 and 3 the mean results. ( g/dl) of TIBC were 295.58 ± 109.53, 324.06 ± 178.00 and 319.88 ± 92.95 and % T.S (%) were 18.78 ± 11.77,26.59 ± 19.40 and 17.97 ± 10.87 percent respectively. The mean total protein was group 1,6.83±l1.77g/dl, group 2,6.39±0.70g/dl and group 3, 6.39 ±0.98 g/dl while the mean albumin (g/dl) in group 1, 2 and 3 were 4.84±0.47, 4.13±0.28 and 4.14±0.29 respectively. The mean values of globulin (g/dl) were 1.98 ± 0.91, 2.29 ± 0.87 and 1.89 ± 0.90 in groups 1, 2 and 3 respectively. As gestational age increased; serum ferritin, total protein, and albumin levels decreased while serum" iron and TIBC increased. The differences in the mean results between the groups were statistically significant (p<0.05) while % T.S and globulin levels when compared showed no significant difference (p>0.05). Iron status showed no statistical difference with increasing parity (p>0.05). However, from this study iron deficiency anaemia was most prevalent in second trimester; hence iron status estimation should be an integral part of routine antenatal care test during second trimester of each pregnancy for proper assessment and management of iron deficiency anaemia in pregnancy.

In many cases of drug-induced immunologic thrombocytopenia (DITP), a metabolite, rather than the native drug, is suspected of provoking the destructive drug-dependent antibodies (DDAB) responsible for this severe hemorrhagic disorder. However, this has not previously been investigated for Qn- and Qd-DDAB. We report evidence that the native drugs, and not their metabolites, are the provocative agents in Qn and Qd DITP. Reactions of Qn- and Qd-DDAB with platelets were studied with the native drugs and four of their metabolites: the N-oxide and 10,11-diol derivatives (quinuclidine ring modifications), the des-methyl derivatives (aromatic quinoline ring modification), and 2'-quininone and 2'-quinidinone (2'-oxo derivatives) (also quinoline ring modifications on Qn and Qd, respectively). Five antibodies were studied:two Group 1 DDAB (specific for compounds with native configuration at asymmetric carbon positions), two Group 2 DDAB (similar to Group 1 DDAB but also known to require the methoxy group on the quinuclidine ring for full activity), and one Group 3 DDAB (reactive with the native drug, its stereoisomer, and several nonmetabolic analogs of both compounds) . Using a complement-dependent 51Cr-lysis assay, the reactions of all DDAB with platelets and the four metabolites were similar to 100-fold weaker when compared to reactions obtained with the native drug, with these exceptions:Group 2 DDAB failed to react with the desmethyl and 2'-oxo metabolites and the Group 3 DDAB failed to react with 2'-oxo Qd. This observation shows that the activity of certain DDAB is critically dependent on the native quinoline ring structure. Importantly, none of the DDAB reacted more strongly with any of the metabolites tested when compared with reactions in the presence of the native drug. These findings indicate that DDAB react with platelets preferentially in the presence of the unaltered Qn and Qd molecules and suggest that, while the role of metabolites cannot be entirely ruled out, the native structure of the drug molecule is sufficient to stimulate production of the antibodies responsible for DITP.

Abstract Background The autonomic nerve system is essential to maintain homeostasis in the body. In the heart, autonomic innervation is important for adjusting the physiology to the continuously changing demands such as stress responses. After cardiac damage, excessive neurite outgrowth, referred to as autonomic hyperinnervation, can occur which is related to ventricular arrhythmias and sudden cardiac death. The cellular basis for this hyperinnervation is as yet unresolved. Here we hypothesize a role for epicardium derived cells (EPDCs) in stimulating sympathetic neurite outgrowth. Purpose To investigate the potential role of adult EPDCs in promoting sympathetic ganglionic outgrowth towards adult myocardium. Method Fetal murine superior cervical ganglia were dissected and co-cultured with activated adult mesenchymal epicardium-derived cells (EPDCs) or/and adult myocardium in a 3D collagen gel culture system. Four experiment groups were included: Group 1: Vehicle cultures (ganglia cultured without EPDC/myocardium) (n=48); Group 2: ganglia co-cultured with EPDCs (n=38); Group 3: ganglia co-cultured with myocardium (n=95); and group 4: ganglia co-cultured with both EPDCs and myocardium (n=96). The occurrence of neurite outgrowth was assessed in each group. The density of neurites that showed directional sprouting (i.e. sprouting towards myocardium) was assessed as well with a semi-automatic quantification method. Finally, sub-analyses were made by taking gender into account. Results Cervical ganglia cultured with EPDCs alone (group 2) showed increased neurite outgrowth compared to vehicle cultures (group 1), however the neurites did not show directional sprouting towards EPDCs. When co-cultured with myocardium (group 3), directional neurite outgrowth towards myocardium was observed. Compared to the ganglia-myocardium co-cultures, directional outgrowth was significantly increased in co-cultures combining myocardium and EPDCs (group 4), and the neurite density was also significantly augmented. Comparison between males and female ganglia demonstrated that more neurite outgrowth occurred in female-derived ganglia than in male-derived ganglia under the same co-culture conditions. Conclusion Activated adult EPDCs promote sympathetic ganglionic outgrowth in vitro. Sex differences exist in the response of ganglia to EPDCs, and female-derived ganglia appear more sensitive to EPDC-signalling. Results support a role of EPDCs in cardiac autonomic innervation and open avenues for exploring of their role in ventricular hyperinnervation after cardiac damage.

The ability of odors to spontaneously trigger specific memories has been widely demonstrated in humans. Although increasing evidence support the role of olfaction on dogs’ emotions and cognitive processes, very little research has been conducted on its relationship with memory in this species. The present study aimed at investigating the role of olfaction in the recall of detailed memories originally formed in the presence of a specific odor (i.e., vanilla). To test this, three groups of participants were trained with the same spatial learning task while a specific odor (i.e., vanilla) was dispersed in the testing room. Subjects were then divided in three experimental groups and after 24 h delay, they were presented with the same spatial task. The first group (Group 1) performed the task in the presence of a novel odor (i.e., control), whereas the second (Group 2) and the third group (Group 3) carried out the test in the presence of the vanilla odor and no odor (Group 3), respectively. After a brief delay, the test was presented again to the three groups of dogs: subjects of Group 1 were now tested in the presence of the vanilla odor, whereas the Group 2 was tested with the control odor. The Group 3 received no odor in both tests. A significant improvement of dogs’ performance was registered in the control-vanilla odors condition (Group 1), suggesting that the exposure to the odor presented at the encoding time would prompt the recall of spatial memories in dogs.

Purpose: to determine the role of a pain symptom in the diagnosis of rhinosinusitis on the background of immune deficiency. 240 patients with rhinosinusitis without pain symptom were divided into 3 groups: group 1 - patients with acute viral rhinosinusitis (AVRS), group 2 - patients with acute bacterial sinusitis (ABRS), group 3 (n = 32) - control. All patients underwent a complete otorhinolaryngological examination, assessment of the pain symptom, an immunogram, the level of SP in the blood serum. At SP > 100 pg/ml in group 1, the change in indicators was typical for viral infection, in group 2, for bacterial infection. With an SP < 100 pg/ml, the cytokine balance is predominantly biased towards anti-inflammatory cytokines, and the direction of differentiation of Th-1/Th-2 lymphocytes towards the Th-2 pathway, which is manifested by immune deficiency, which leads to severe or prolonged course of the disease, which may indicate impaired neuro-immune interactions.

Aim: to improve efficacy of predicting preterm labor in the first trimester of pregnancy by combining diverse parameters of cervical ultrasound examination.Materials and methods. A prospective cohort study of 1517 women with uncomplicated pregnancy was performed. Inclusion criteria were: females underwent cervicometry at 11–14 weeks of gestation, singleton pregnancy, revealing no complaints at the onset of examination. All women were subdivided into four groups: Group 1 – 27 pregnant women with shortened cervix (less than 30 mm); Group 2 – 24 pregnant women without cervical gland area (СGA); Group 3 – 30 pregnant women with two risk factors (shortened cervix less than 30 mm and lacked СGA); Group 4 (control) consisted of 1436 pregnant women with cervix length exceeding 30 mm and presence of СGA.Results. Average delivery term in Group 1 was 35.7 weeks (95 % CI = 34.7–36.8), in Group 2 – 34.7 weeks (95 % CI = 33.59–35.0), in Group 3 – 33.23 weeks (95 % CI = 31.6–34.8), in Group 4 (control) – 38.11 weeks (95 % CI = 38.06–38.17). A significant moderate correlation (Rxy = 0.534) between shortened cervix, absence of СGA and delivery term was found (p < 0.001). A regression model consisting of cervical length and presence of СGA was simulated based upon 50.8 % factors underlying probability of preterm birth, revealing 42.6 % sensitivity, 99.1 % specificity, and 96.6 % overall diagnostic value. The area under the ROC curve was 0.902 ± 0.022 (95 % CI = 0.860–0.945). The data obtained reflect diverse biochemical changes such as collagen decomposition, altered glucosamine level and fluid amount within cervical tissues. Such processes result in shortened, softened and expanded (matured) cervix. Uncovering markers for preterm cervical maturation underlies a logical strategy to predict miscarriage.Conclusion. Untrasound cervical measurement in the first trimester of pregnancy allows for revealing valuable miscarriage predictors (shortened cervix and absence of GI). Risk assessment by combining diverse ultrasound cervix parameters would allow to improve overall predictive efficacy.

The study aims at evaluating the protective effects of Ajwa dates extract against diclofenac sodium (DFS)-induced nephrotoxicity. A total of 30 male albino mice were divided into three groups. Group 1 received water per oral gavage for 14 days and saline per intra-peritoneal (IP) dose for the days 12–14. Group 2 received water like Group 1 and a daily IP dose of DFS for the days 12–14. Group 3 received 1 gm/kg Ajwa extract in water for 14 days and a daily IP dose for the days 12–14. Biochemical investigation revealed DFS-induced increase in serum urea and creatinine levels along with depleted antioxidant capacity, altered lipid profile, and hyperglycemia. Ajwa extract successfully protected against DFS-induced adverse effects, normalizing renal parameters biochemically and histologically, and prevented its hyperlipidemic and hyperglycemic effects. Ajwa protected against endogenous antioxidant capacity depletion in treated animals. Hydroalcoholic Ajwa extract is a promising candidate for protection against DFS-induced hyperlipidemia and nephrotoxicity.

Temperate bacteriophages of diverse morphology were demonstrated by electron microscopy in toxigenic cultures of Clostridium botulinum. The 41 strains examined included 23 type E and multiple representatives of all other types. Cultures induced with mitomycin-C generally gave better yields, but phages were also demonstrable in untreated cultures.A provisional grouping of toxigenic types into four categories is suggested, based mainly upon associated phage patterns. Group 1 comprises types A, B, and F (all proteolytic), many of whose cultures showed an icosahedral contractile phage; others contained a "bullrushy" phage with elongated head and long flexible tail; some strains yielded both. Group 2, types B and F (non-proteolytic), were associated with icosahedral contractile phages; the latter also had an octahedral flexible phage. Group 3, types C and D, yielded conspicuously large phages with octahedral heads and very long sheathed tails. One type C strain produced a long-tailed icosahedral phage. Type E phages constituted group 4. These were icosahedral with tails generally contracted but sometimes flexible, often accompanied by superfluous sheathed tail-like structures resembling certain bacteriocins. Although non-toxigenic "OS" mutants of types A, B, E, and F were phageless, two non-toxic type E strains yielded phages. The possible role of lysogeny in the toxigenicity of certain types of this species is likely to prove difficult to elucidate.

AbstractOrthodontic relapse after orthodontic treatment is a major clinical issue in the dental field. However, the biological mechanism of orthodontic relapse is still unclear. This study aimed to establish a mouse model of orthodontic retention to examine how retention affects the rate and the amount of orthodontic relapse. We also sought to examine the role of osteoclastogenesis in relapse using an antibody to block the activity of M-CSF, an essential factor of osteoclast formation. Mice were treated with a nickel-titanium closed-coil spring that was fixed between the upper incisors and the upper-left first molar to move the first molar in a mesial direction over 12 days. Mice were randomly divided into three groups: group 1, no retention (G1); group 2, retention for 2 weeks (G2); and group 3, retention for 4 weeks (G3). In G2 and G3, a light-cured resin was placed in the space between the first and second molars as a model of retention. Orthodontic relapse was assessed by measuring changes in the dimensions of the gap created between the first and second molars. To assess the activity and role of osteoclasts, mice in G3 were injected with anti-c-Fms antibody or PBS, and assessed for changes in relapse distance and rate. Overall, we found that a longer retention period was associated with a slower rate of relapse and a shorter overall amount of relapse. In addition, inhibiting osteoclast formation using the anti-c-Fms antibody also reduced orthodontic relapse. These results suggest that M-CSF and/or its receptor could be potential therapeutic targets in the prevention and treatment of orthodontic relapse.
