The aim of this study was to evaluate the performance of potato clonal families, and to estimate genetic variance, heritability and the expected response to selection of tuber yield and appearance traits in early generations. Twelve potato families were obtained from crosses between two groups of randomly-selected genotypes, including Eliza, C1730-7-94, and C-1742-8-95 in group 1; and Shepody, Asterix, Caesar, and White Lady in group 2. The crosses were made in factorial design (3 genotypes x4 genotypes), and each family consisted of 75 genotypes. Experiments were conducted in the fall of 2010, with a seedling generation under greenhouse conditions, and in the fall of 2011, with a clonal generation under field condition. High heritability estimates suggest that mild to moderate selection can be applied in the seedling generation to eye depth, eyebrow prominence, tuber curvature, flattening and shape uniformity. The C1742-8-95/White Lady stood out as a superior cross, as did all other crosses with White Lady, regarding tuber appearance and yield traits.

Abstract The aim of this study was to evaluate the efficiency of selection of potato families in early generations for heat tolerance. Thirty families were evaluated in the seedling generation (SG), first clonal generation (FCG) in the field and greenhouse under high temperature conditions, and second clonal generation (SCG) under mild temperatures. The mean of the families was obtained in each generation. The 16 most productive families in FCG were selected, and the clones of these families were evaluated in experiments in the winter and rainy crop seasons. The results showed that family selection for tuber shape may be applied as of the SG. It was also observed that family selection in the FCG and SCG for yield and tuber specific gravity contributed to identification of clones tolerant to heat and responsive to environmental improvement.

The aim of this study was to discuss the new methods of clinical classification and staging of patients with myasthenia gravis (MG) proposed by our group and to summarize the experiences of surgical treatment of MG with a novel incision by cutting the sternum cross-sectionally at the second intercostal level. A retrospective analysis was made for the clinical data from the patients with MG who underwent thymectomy from July 1988 to May 2009. The surgical procedures were designed into three groups, a group with Osserman classification and median incision of the sternum (Group 1), a group with MGFA typing (Myasthenia Gravis Foundation of America) and a small transverse sternal incision at the second intercostal level (Group 2), and a group with new typing and a smaller transverse sternal incision at the second intercostal level (Group 3). Observation of the clinical typing and staging was made in the patients with myasthenia crisis. The parameters such as procedure duration in Group 2 and 3 was significantly lower than those in Group 1 ( P < 0.05). The incidence of myasthenia crisis in Group 3 was significantly lower than that in Groups 2 and 3 ( P < 0.05). The procedure with a smaller transverse sternal incision at the second intercostal level (Group 3) is a safer method for patients with MG. The combination of this procedure with the new typing and staging methods proposed by our group could facilitate the selection of operation indications and opportunity, resulting in the lower incidence of myasthenia crisis and mortality. Our new procedure is well deserved to be a preferential selection by other hospitals.

The selection of potato clones for yield is usually effective from the second clonal generation. It would however be ideal to select from the seedling generation (SG) or the first clonal generation (FCG). The aim of this study was to evaluate the repeatability of selection at the family level performed in the early generations with the subsequent generations, for tuber yield and specific gravity in the warm season. Thirty families were evaluated in the SG, FCG and the second, third and fourth clonal generation, without any selection. In this way, adjusted means of the 30 families were obtained for each generation. Selections were simulated independently in the different family generations, and then the repeatability of these families among generations verified, using the same selection intensity. The results showed that the family selection in the SG and FCG for specific gravity and in the FCG for tuber yield is efficient, at mild as well as warm temperatures.

Relevance. Odontogenic infection is one of the most important problems of dental science. The variety of anti-inflammatory oral hygiene products determines the need for targeted selection of preventive toothpastes and rinses, balms, foams, elixirs, as well as monitoring and training the algorithm of hygienic measures for a patient with an odontogenic infection. The aim of the study was to study the hygienic status of the adult population for the selection of individual oral hygiene products for odontogenic infection, taking into account social and hygienic factors.Materials and methods. The study examined the prevalence of odontogenic infection in the adult population to determine the need for professional care and dental education. The study involved 198 people without somatic pathology, who were allocated into four groups according to the performed oral care and taking into account the dental status and the intensity of oral microbiota formation in the adult population. The patients were followed-up every week for one month. The study examined the simplified oral hygiene index by GreenVermillion (OHI-S), PMA index and Mühlemann and Son sulcus bleeding index, which allowed calculating the effectiveness of oral care products.Results. The preventive care effectiveness evaluation showed an increase in the cleansing effect in the adult population over the entire study period. The anti-inflammatory effectiveness analysis demonstrated positive changes: by the end of the study, the PMA index was 51.52 ± 3.40% in group 1; it increased by a factor of 3 and amounted to 44.17 ± 2.77% in group 2; 56.51 ± 4.61% – in group 3, 48.95 ± 3.60% – in group 4. The Mühlemann and Son sulcus bleeding index demonstrated the changes in the periodontal tissue condition and amounted to 52.78 ± 3.62% in group 1, 44.11 ± 3.54% in group 2, 54.97 ± 3.98% in group 3, 47.78 ± 2.73% in group 4.Conclusions. The development of oral health promotion measures determines the significance of oral care products for the prevention of odontogenic infection in the adult population, which plays a crucial role in the individual program planning for the main dental disease prevention.

P51 Background and Purpose: The ischemic penumbra is composed of neurons that are functionally impaired but structurally intact, and thus potentially salvageable. Identifying the penumbra and its relationship with the ischemic core may lead to a more physiologic selection of patients who might benefit from recanalization therapy. We sought to explore the core/penumbra relationship by quantitatively measuring cerebral blood flow (CBF) in patients with acute M1 occlusion. Methods: 19 patients with M1 occlusion proven by CT angiography or conventional cerebral angiography underwent a Xe-CT/CBF study within 6 hours of symptoms onset. Mean CBF values were measured in the ipsilateral cortical MCA territory. The core was defined as areas with CBF< 8 ml/100g/min and the penumbra was defined as areas with CBF 9–20 ml/100g/min. Findings were correlated with the admission NIH stroke scale (NIHSS). Results: In 6/19 patients (31.5%)(group 1), the size of the penumbra was greater than twice the size of the core. In 8/19 patients (42.1%) (group 2), the size of the penumbra was approximately equal the size of the core. In 5/19 patients (26.8%)(group 3) the size of the penumbra was less than half the size of the core. The median core volumes for each of the three groups, expressed as percentage of core relative to ipsilateral cortical MCA territory, increased from group 1 to group 3. While there was a trend towards a correlation between the admission NIHSS and the combined core and penumbral volumes, no such correlation could be established between admission NIHSS and core or penumbral volumes alone. Conclusions: In the first 6 hours after M1 occlusion, penumbral volumes that are larger than or equal to core volumes are present in 14 out of 19 patients. A smaller core volume is associated with an increased penumbra to core ratio. The admission NIHSS in patients with M1 occlusion correlates with the combined volumes of core and penumbra.

Abstract The Abstract reviews the experience of implementing Vytelle technology in ZhanaBereke LLP, Akmola region in Kazakhstan. The trial objects are Qazaq Aqbas bull calves: group 1 aged 10–11 months (n = 22), group 2 aged 11–12 months (n = 24). Data analysis showed that more reliable Residual Feed Intake calculated for each individual animal on the basis of their phenotypes and information on pedigree, were found in group 1. The average RFI EPD for group 1 is -0.0607, for group 2 is -0.0297. The RFI% Rank in terms of RFI EPD for both trial groups varied within 4 ... 96%. However, the average RFI% Rank was lower in the first group (45%) compared to the second group (56%). From which it follows that the RFI EPD is higher in group 1. Average Daily Gain EPDs (ADG EPD) higher in group 1 -0.0018. A higher ADG EPDs indicate a more cost-effective metric. The ADG% Rank in terms of ADG EPD for group 1 varied within 1 ... 62%, for group 2: 1 ... 63%. The average ADG% Rank was slightly lower in the first group (30%) compared to the second group (33%). From the presented data, it follows that the breeding valueaccording to the ADG EPD is higher in group 1. The average Dry Matter Intake by animals per day during the trial (DMI EPD) is equal to -0,0600 in the first group, and -0,0292 in the second group. The DMI% RANK in terms of DMI EPD for group 1 varied within 31 ... 93%, for group 2: 38 ... 96%. The DMI% RANK was lower in the first group (60%) compared to the second group (67%). Summarizing the above, we can conclude that selection for this characteristic is less effective, work will continue to increase this indicator.

Purpose. To improve the duodenum function after Kimura surgery which is performed for the congenital duodenal obstruction by restoring the horseshoe-shaped duodenum. Material and methods. A comparative analysis of two groups of patients was made: In Group 1 (n = 31) , patients were operated with the mobilization of lower horizontal duodenal branch and duodenoduodenal anastomosis by Kimura without restoring the horseshoe-shape of the duodenum. In Group 2 (n = 11), children had similar surgeries but the horseshoe-shaped configuration of the duodenum was restored by fixing the initial part of the jejunum to the Treitz ligament. After surgery, the researchers radiographically compared time of barium suspension passage through the duodenum in patients of both groups. Results. In children from Group 1, passage of the contrast suspension via duodenum lasted for 43.9 ± 3.9 sec., what is approximately 2 times faster than in the norm. In patients from Group 2, this indicator was 3-4 times larger than in patients from Group 1 and was 158.2 ± 18.2 sec. Such a slowdown in the chyme passage along the duodenum prolongs exposure of food masses to pancreatic juice, bile and intestinal juice and, consequently, improves the duodenal function. Conclusion. The authors recommend to end the surgical intervention for eliminating congenital duodenal obstruction by Kimura technique with the restoration of horseshoe-shaped duodenum by fixing the initial part of the jejunum to the Treitz ligament.

The attempt of this article was to assess reliability of Little’s Irregularity Index (LII) as for stability of the treatment outcomes in adults with crowded mandibular incisors. LII was measured on a digital cast prior to an orthodontic treatment (T1) of the 302 patients thus allowing us to establish the treatment plan, which called for (a) expansion (group 1), interproximal stripping (group 2), or extraction of one of the mandibular incisors. LII was measured after debonding (T2) and a year after retention (T3). Treatment resulted in significant reduction of LII values after treatment, in T1-T2 period in all groups. As for T2-T3 period it brought significant but clinically irrelevant relapse that occurred in groups 1 and 2; group 3 presented with insignificant improvement of occlusion. Conclusively, 30 years after introducing LII it has been a reliable parameter that allows selection of optimal treatment methods, provided that the appropriate ranges of values displaying dentoalveolar discrepancy are obeyed, namely, (1) up to 3 mm: expansion, (2) from 3 to 5 mm: interproximal enamel reduction, and (3) above 5 mm: extraction.
