The objective of the research was to study and assess the quality of prosthetic treatment using aesthetic fixed restorations.Materials and methods. The study included 79 patients without a comorbidity who underwent prosthetic rehabilitation. All the patients were divided into 3 groups: Group I included 25 patients with metal-plastic restorations; Group II comprised 34 patients with porcelain-fused-to-metal restorations; Group III consisted of 20 patients with a combined occlusal surface of prosthetic restorations. The patients were observed 6 months after prosthetic repair. Only patients with single molar and premolar crowns were examined. Bridge prostheses were not taken into account in order to eliminate the effect of masticatory force redistribution on the abutment crowns.Results. In Group I, 11 (44%) patients were satisfied with the results of prosthetic treatment. In Group II, 25 (78.12%) patients reported that they were satisfied with their treatment. In Group III, there were 17 (85%) patients satisfied with their outcome. However, the patients’ complaints are often subjective and do not fully reflect the objective state of the dentoalveolar system. An objective examination revealed that in indirect restorations, marginal periodontium pathology is typical. Conclusions. Aesthetic fixed restorations with a combined occlusal surface have demonstrated good clinical results, even at long-term follow-up. Combining positive properties of two different construction materials, namely zirconium dioxide and ceramics, they reduce the risk of complications such as marginal periodontium pathology and chipping along the occlusal surface as well as contribute to minimal abrasion of the occlusal surfaces of the antagonistic teeth. We cannot recommend metal-plastic restorations due to their low clinical effectiveness, poor aesthetic qualities as well as a high level of marginal periodontium pathology.

The objective of the research was to study the peculiarities of the combination of zirconia and ceramic occlusal surfaces when constructing aesthetic fixed prosthetic appliances.Materials and methods. The study included 70 patients with zirconia and ceramic occlusal surfaces of aesthetic fixed dental prostheses. Group I included 24 patients with a combination of zirconia and ceramic occlusal surfaces. Group II included 30 patients with a combination of ceramic occlusal surfaces. Group III included 16 patients with a combination of zirconia occlusal surfaces. All the patients were observed 12 and 24 months after prosthetic repair.Results. 12 and 24 months after prosthetic repair, the occlusal contact surface area was the largest in Group II (8.18±0.16 mm2 and 9.17±0.1 mm2, respectively). In Group I, where only one occlusive surface was made of zirconium dioxide, significantly reduced levels of abrasion were observed as compared to Group II – 8.07±0.21 mm2 and 8.65±0.23 mm2, respectively. 36 months after denture wearing, in Group III, the smallest contact surface area – 7.84±0.15 mm2as well as the lowest growth of the surface area was observed – 8.07±0.13 mm2.Conclusions. Dental prostheses with at least one ceramic occlusal surface exhibit a strong tendency to abrasion and, consequently, to an increase in the occlusal surface area resulting in an excessive load on prosthetic appliance. Moreover, functional and aesthetic values of prosthetic prosthesis sharply decrease. Therefore, we recommend to produce zirconia occlusal surface or at least to combine the same materials, as it will increase the longevity of prosthetic appliance.

Background: One purpose of operative dentistry is the maintenance of healthy pulp by reducing the need for root canal treatment and the possibility of undesirable scenarios such as tooth loss. Propolis is a plant-derived substance that contains a resin produced by honeybees belonging to the Apis mellifera species. Purpose: This study aimed to investigate the effect of a combination of calcium hydroxide (Ca(OH)2) and propolis extract on odontoblast-like cell proliferation in Wistar rats (Rattus norvegicus). Methods: This research constituted a true experimental laboratory-based investigation with post-test control group design. Thirty Wistar rats were randomly divided into six groups. The first molar pulp of each sample was perforated on occlusal surfaces using a low speed round bur. On day 3, the samples were divided into six groups (n=10): Group I: control; Group II: Ca(OH)2 + 11%; propolis extract; Group III: Ca(OH)2 + aquadest, and on day 7: Group IV: control; Group V: Ca(OH)2 + 11% propolis extract; Group VI: Ca(OH)2 + aquadest. All samples were filled with restorative material. They were subsequently sacrificed after 3 and 7 days post-pulp capping administration and the afflicted tooth extracted for hematoxylin and eosin (H&E) staining. The resulting data was subjected to statistical analysis to ascertain the proliferation of odontoblast-like cells. The significance of differences between the groups was determined by a one-way ANOVA test followed by a post hoc Tuckey HSD. A p-value <0.05 was considered to be significant. Results: On day 3, a significant difference existed between group II (Ca(OH)2–propolis) and group I (control group) and group III (Ca(OH)2–aquades), whereas Ca(OH)2–propolis revealed that the proliferation of odontoblast-like cells was higher. Meanwhile, on day 7, there was a significant difference between all groups whereas, with regard to Ca(OH)2–propolis, the proliferation of odontoblast-like cells in group V was higher. Conclusion: Application of combination of Ca(OH)2-propolis extract can increase the proliferation of odontoblast-like cells in pulp tissue on days 3 and 7.

Pregnancy is a condition of modulated immune suppression, so this group of patients has increased risk of infectious diseases.Trivalent subunit vaccines, unadjusted Agrippal S1 (group I) and immunoadjuvant Grippol Plus (group II), containing 5 μg of actual influenza virus strains, were administered respectively to 37 and 42 women in the second and third trimester of physiological pregnancy.The administration of subunit influenza vaccines was accompanied by the development of local reactions in no more than 10% of patients, compared with 4.9% of the 41 pregnant women in the placebo group (group III). Systemic reactions were of a general somatic nature, did not differ between vaccinated and placebo groups, and were not associated with vaccination. Physiological births in groups I, II and III were 94.6%, 92.9% and 85.4%, respectively, and the birth rates of children without pathologies were 91.9%, 90.5% and 80.5%, respectively, and were comparable between groups. Vaccination stimulated the production of protective antibodies against influenza virus strains in 64.8–94.5% of patients after immunisation with an unadjusted vaccine and in 72.5–90.0% of patients after the administration of an immunoadjuvant vaccine. After 9 months, antibody levels were recorded in 51.3–72.9% in group I and 54.2–74.2% in group II. Immunisation against influenza in pregnant women provided a high level of seroprotection and seroconversion. Nevertheless, the level of seroprotection against the influenza strain A(H3N2, Victoria) was slightly lower in the group immunised with an unadjusted vaccine compared to those vaccinated with the immunoadjuvant vaccine.

Pituitary Suppression

Objective To compare the clinical results of four different protocols of COH for IVF-ICSI in normovulatory women, using in all cases pituitary suppression with GnRH antagonists. Materials/methods A single center, open label, parallel-controlled, prospective, post-authorization study under the approved conditions for use where 305 normal responders women who were candidates to COH were assigned to r-FSH + hp-hMG (n = 51, Group I), hp-hMG (n = 61, Group II), fixed-dose r-FSH (n = 118, Group III), and r-FSH with potential dose adjustment (n = 75, Group IV) to subsequently undergo IVF-ICSI. Results During stimulation, Group IV needed significantly more days of stimulation as compared to Group II [8.09 ± 1.25 vs. 7.62 ± 1.17; P < 0.05], but was the group in which more oocytes were recovered [Group I: 9.43 ± 4.99 vs. Group II: 8.96 ± 4.82 vs. Group III: 8.78 ± 3.72 vs. Group IV: 11.62 ± 5.80; P < 0.05]. No significant differences were seen between the groups in terms of clinical and ongoing pregnancy, but among patients in whom two embryos with similar quality parameters (ASEBIR) were transferred, the group treated with hp-hMG alone achieved a significantly greater clinical pregnancy rate as compared to all other groups [Group I: 31.6%, Group II: 56.4%, Group III: 28.7%, Group IV: 32.7%; P < 0.05]. Conclusions Although randomized clinical trials should be conducted to achieve a more reliable conclusion, these observations support the concept that stimulation with hp-hMG could be beneficial in normal responders women undergoing pituitary suppression with GnRH antagonists.

The objective of the research was to evaluate the clinical effectiveness of using aesthetic fixed prosthetic appliances with combined occlusal surface.Materials and methods. The study included 30 patients who were divided into 2 groups: Group I included 20 patients with combined occlusal surface of the crowns; Group II included 22 patients with ceramic occlusal surface of the crowns. The patients were observed 3, 6 and 12 months after prosthetic repair.Results. 6 months after prosthetic repair, the occlusal contact surface area in Group I increased by 0.79%, while in Group II, it increased by 1.4%.12 months after prosthetic repair, the occlusal contact surface area in Group I and Group II increased by 2.37% and 5%, respectively.The aforementioned data indicated that the occlusal contact surface area increased as the period of ceramic fixed prosthetic appliance wearing increased.When combining the occlusal surface in dental prostheses, the occlusal contact surface area increased approximately 2 times slower. The study demonstrated convincingly that crowns burnt on a zirconium dioxide frame were a better choice as compared to cast framework made of nickel-cobalt-chrome alloy. In case of cast frameworks, the indicators of crown margin discrepancy were worse than in case of milled frameworks - 15% versus 5%, respectively. In addition, one cast framework crown (5%) in Group II was remodeled and one crown (5%) was recemented.Conclusions. Aesthetic fixed prosthetic appliances with combined occlusal surface demonstrated high functional and aesthetic characteristics. The use of the USHPS system showed a decisive advantage of milled frameworks and combined occlusal surface over traditional cast ceramic frameworks.The combination of high mechanical, strength and tribological properties of zirconium dioxide and high biological as well as aesthetic properties of ceramic materials helped reveal high clinical characteristics of aesthetic appliances with combined occlusal surface.

SummaryMost anticardiolipin antibodies (ACA) associated with antiphospholipid syndrome (APS) are directed against epitopes expressed on β2-glycoprotein I (β2GPI). Despite a good correlation between standard ACA assays and those using purified human β2GPI as the sole antigen, some sera from APS patients only react in the latter. This is indicative of heterogeneity in anti-β2GPI antibodies. To characterize their reactivity profiles, human and bovine β2GPI were immobilized on γ-irradiated plates (β2GPI-ELISA), plain polystyrene precoated with increasing cardiolipin concentrations (CL/β2GPI-ELISA), and affinity columns. Fluid-phase inhibition experiments were also carried out with both proteins. Of 56 selected sera, restricted recognition of bovine or human β2GPI occurred respectively in 10/29 IgA-positive and 9/22 IgM-positive samples, and most of the latter (8/9) were missed by the standard ACA assay, as expected from a previous study. Based on species specificity and ACA results, IgG-positive samples (53/56) were categorized into three groups: antibodies reactive to bovine β2GPI only (group I) or to bovine and human β2GPI, group II being ACA-negative, and group III being ACA-positive. The most important group, group III (n = 33) was characterized by (i) binding when β2GPI was immobilized on γ-irradiated polystyrene or cardiolipin at sufficient concentration (regardless of β2GPI density, as assessed using 125I-β2GPI); (ii) and low avidity binding to fluid-phase β2GPI (Kd in the range 10–5 M). In contrast, all six group II samples showed (i) ability to bind human and bovine β2GPI immobilized on non-irradiated plates; (ii) concentration-dependent blockade of binding by cardiolipin, suggesting epitope location in the vicinity of the phospholipid binding site on native β2GPI; (iii) and relative avidities approximately 100-fold higher than in group III. Group I patients were heterogeneous with respect to CL/β2GPI-ELISA and ACA results (6/14 scored negative), possibly reflecting antibody differences in terms of avidity and epitope specificity. Affinity fractionation of 23 sera showed the existence, in individual patients, of various combinations of antibody subsets solely reactive to human or bovine β2GPI, together with cross-species reactive subsets present in all samples with dual reactivity namely groups III and II, although the latter antibodies were poorly purified on either column. Therefore, the mode of presentation of β2GPI greatly influences its recognition by anti-β2GPI antibodies with marked inter-individual heterogeneity, in relation to ACA quantitation and, possibly, disease presentation and pathogenesis.

<p class="p1"><span class="s1"><strong>Background:</strong> The inspiratory oxygen fraction (FiO<sub>2</sub>) is usually set between 60% and 100% during conventional extracorporeal circulation (ECC). However, this strategy causes partial oxygen pressure (PaO<sub>2</sub>) to reach hyperoxemic levels (&gt;180 mmHg). During anesthetic management of cardiothoracic surgery it is important to keep PaO<sub>2</sub> levels between 80-180 mmHg. The aim of this study was to assess whether adjusting FiO<sub>2</sub> levels in accordance with body temperature and body surface area (BSA) during ECC is an effective method for maintaining normoxemic PaO<sub>2</sub> during cardiac surgery.</span></p><p class="p1"><span class="s1"><strong>Methods:</strong> After approval from the Ethics Committee of the University of Acıbadem, informed consent was given from 60 patients. FiO<sub>2</sub> adjustment strategies applied to the patients in the groups were as follows: FiO<sub>2</sub> levels were set as 0.21 × BSA during hypothermia and 0.21 × BSA + 10 during rewarming in Group I; 0.18 × BSA during hypothermia and 0.18 × BSA + 15 during rewarming in Group II; and 0.18 × BSA during hypothermia and variable with body temperature during rewarming in Group III. Arterial blood gas values and hemodynamic parameters were recorded before ECC (T1); at the 10th minute of cross clamp (T2); when the esophageal temperature (OT) reached 34°C (T3); when OT reached 36°C (T4); and just before the cessation of ECC (T5).</span></p><p class="p1"><span class="s1"><strong>Results:</strong> Mean PaO<sub>2</sub> was significantly higher in Group I than in Group II at T2 and T3 (<em>P</em> = .0001 and <em>P</em> = .0001, respectively); in Group I than in Group III at T1 (<em>P</em> = .02); and in Group II than in Group III at T2, T3, and T4 <br /> (<em>P</em> = .0001 for all). </span></p><p class="p1"><span class="s1"><strong>Conclusion: </strong>Adjustment of FiO<sub>2</sub> according to BSA rather than keeping it at a constant level is more appropriate for keeping PaO<sub>2</sub> between safe level limits.

The article presents the comparative analysis of the state of the cervix in women with endometrial polyps and micropolyps. Patients and methods. The study involved 130 patients aged 18-35 years: 70 patients with endometrial polyps (group I), 30 patients with micropolyps (group II) and 30 patients of the control group (group III). Results. According to the anamnesis of women in the I group were significantly more frequent diseases of the cervix, which corrected physical surgery methods, in particular cryodestruction. In group II, the representatives of these indicators were similar to healthy. Normal colposcopic picture met significantly less frequently in patients and I, and II group. The differences in the incidence of HPV high oncogenic risk in all groups were not statistically significant. Conclusion. Destructive methods used in the detection of any changes in the cervix are often overly aggressive, form scars and contributing to inflamaciones process. In the chain of events leading to the formation of PE, cervical pathology and its correction can take the basic place.

Изучено влияние кормовой добавки в форме индивидуальных болюсов Метраболь на возможность снижения негативного влияния субклинического кетоза (СКК) и результативность искусственного осеменения высокопродуктивных молочных коров в посттранзитный период. Животные были подобраны по принципу условных аналогов и разделены на 3 группы в зависимости от концентрации β-оксимасляной кислоты в их крови. В I группе (n=18) у коров не было СКК, концентрация кислоты составляла <1,0 ммоль/л, во II группе (n=21) у животных зарегистрирован СКК, концентрация кислоты — 1,0…1,4 ммоль/л. С целью поиска решения по снижению негативного влияния СКК на репродуктивные показатели была сформирована III группа коров, переболевших СКК (n=24) с концентрацией β-оксимасляной кислоты в крови 1,0…1,4 ммоль/л, но с использованием болюсов, применяемых для ускоренного восстановления репродуктивной функции коров после отела. Важной составляющей опыта явилось то, что к моменту гормональной синхронизации у коров всех 3 групп фиксировалось отсутствие СКК (снижение β-оксимасляной кислоты до уровня <1,0 ммоль/л). Для синхронизации полового цикла выбрана схема Пресинх-овсинх. Установлено, что гормональная синхронизация животных, перенесших СКК, в сравнении со здоровыми, не позволяет снизить негативное влияние данного нарушения обмена веществ. Во II группе у животных зафиксированы самые низкие репродуктивные показатели (количество использованных доз; индекс осеменения, сервис-период; время от первого до успешного осеменения; результат первичного осеменения; количество животных, осемененных 3 и более раз). В III группе применение болюсов позволило, в сравнении с животными II группы, не только избежать отрицательного воздействия СКК, но и превзойти по изучаемым параметрам животных из I группы. The effect of the feed additive in the form of individual boluses Metrabol on the possibility of reducing the negative effect of subclinical ketosis (CCK) and the effectiveness of artificial insemination of highly productive dairy cows in the post-transit period was studied. The animals were selected according to the principle of conditional analogs and divided into 3 groups depending on the concentration of β-hydroxybutyric acid in their blood. In group I (n=18), the cows did not have SSC, the acid concentration was <1.0 mmol/L, in group II (n=21), SSC was registered in animals — 1.0...1.4 mmol / L. In order to find a solution to reduce the negative effect of CCB on reproductive indices, a group III of cows was formed who had CCB (n = 24) with a concentration of β-hydroxybutyric acid in their blood of 1.0...1.4 mmol/L, but using boluses, used to accelerate the restoration of the reproductive function of cows after calving. An important component of the experiment was that by the time of hormonal synchronization, cows of all 3 groups had no SSC (decrease in β-hydroxybutyric acid to a level of <1.0 mmol/L). To synchronize the sexual cycle, the Pressinh-ovsinh scheme was chosen. It was found that hormonal synchronization of animals that underwent SSC, in comparison with healthy ones, does not allow reducing the negative effect of this metabolic disorder. In group II, animals had the lowest reproductive indices (number of doses used; insemination index, service period; time from first to successful insemination; result of primary insemination; number of animals inseminated 3 or more times). In group III, the use of boluses made it possible, in comparison with animals of group II, not only to avoid the negative effect of SSC, but also to surpass the animals from group I in terms of the studied parameters.
