Introgressions of Vitis rotundifolia Michx. to obtain grapevine genotypes with complex resistance to biotic and abiotic stresses
Vitis rotundifolia Michx. is one of the species of the family Vitaceae, with resistance to both biotic and abiotic stresses. The present study reports new scientific knowledge about the inheritance of resistance to downy mildew, powdery mildew and frost by V. vinifera varieties from V. rotundifolia. Recombinant lines of three hybrid populations from the crossing of the maternal genotype âM. 31-77-10 with V. rotundifolia hybrids were used as the object of the study. As a result of laboratory screening, more than 40 % of recombinants of the âM. 31-77-10Ă Ă[DRX-M5-734+DRX-M5-753+DRX-M5-790] population showed a high degree of frost resistance (â24 °C), while 6 % of transgressive recombinants were characterized by a very high degree of resistance (â27 °Х). The maternal genotype âM. 31-77-10 does not carry alleles of resistance to powdery mildew at the Run1 locus and in the field suffers from powdery mildew much more than the paternal genotypes. The prevalence of powdery mildew on vegetative organs in the three recombinant populations over the years varies on average between 3.2â17.1, 0.3â17.7 and 0.6â5.2 %, respectively. As a result, almost all recombinant genotypes that received a resistant allele from the paternal genome are highly resistant to powdery mildew
Description of the Vitis vinifera L. phenotypic variability in eno-carpological traits by a Euro-Asiatic collaborative network among ampelographic collections
The grapevine intra-specific variability captured an increasing interest during the last decades, as demonstrated by the number of recently funded European projects focused on the grapevine biodiversity preservation. However, nowadays, crop plants are mainly characterized by genotyping methods. The present work summarizes the phenotype data collected among 20 ampelographic collections spread in 15 countries, covering mostly of the viticultural areas in the Euro-Asiatic range: from Portugal to Armenia and from Cyprus to Luxembourg. Together with agro-climatic characterization of the experimental site, in two years, about 2400 accessions were described, following a common experimental protocol mainly focused on the carpological and oenological traits, obtaining a general overview of the distribution of the considered phenotypic traits in the cultivated Vitis vinifera species. The most replicated cultivars were selected and, for the subset of these reference cultivars, their behavior in the different environmental conditions over sites and years was described by ANOVA methods

BACTERIOTOXIC LIGHTTHERAPY APPLICATION IN COMPLEX CURE OF PARODONT TISSUESâ INFLAMMATORY DISEASES
The prevalence of periodontal diseases of varying severity affects more than 90% of the adult population, and the problem of increasing the effectiveness of its treatment is very important. One of the promising methods of treatment is antibiotic therapy with the use of probiotic microorganisms and antioxidants. The contomitant use effectiveness of antibacterial BTC-therapy, Linex probioticsŸ and Xylax forteŸ, antioxidant ubixion (coenzim Q 10) for microbiocenosis gingival pockets' sanation was investigated on 60 patients with inveterate severe generalized periodontitis. It was found that pathogenic microflora volume decreased in 21,3±0,7(
FEATURES OF USING NONSTEROIDAL ANTI-INFLAMMATORY DRUGS IN DENTAL PRACTICE
Aim. This study was conducted to assess the awareness of dentists about the questions of pharmacokinetics and pharmacodynamics of nonsteroidal anti-inflammatory drugs as well as to study the features of their use for the relief of pain syndrome in dental practice.Materials and methods. By means of the questionnaires were studied 107 dentists working in dental clinics and dental departments of General hospitals, especially their use of the nonsteroidal anti-inflammatory drugs for pain relief.Results. It was determined that 85% of doctors use non-selective and moderately selective cyclooxygenase inhibitors (COX), 15%-prefer Cox-2 inhibitor with the pronounced selectivity for pain relief. The highest number of correct answers was given by a group of doctors with work experience from 5 to 10 years (40.3%), the lowest â by doctors with work experience more than 20 years, respectively 40.3% and 36.1% of the total number of doctors from the studied groups.Conclusion. There was noted that it is necessary to pay attention to the peculiarities of pain relief for the improvement of dentistsâ work as well as to involve clinical pharmacologists for these purposes
