Novel Approaches to Possible Targeted Therapies and Prophylaxis of Uterine Fibroids.

Uterine leiomyomas are the most common benign tumors in women of childbearing age. They may lead to problems of conception or complications during the gestational period. The methods of treatment include surgical (myomectomy and hysterectomy, embolization of arteries) and therapeutic treatment (ulipristal acetate, leuprolide acetate, cetrorelix, goserelin, mifepristone).

In Vivo Antimicrobial and Wound-Healing Activity of Resveratrol, Dihydroquercetin, and Dihydromyricetin against , and .

An increase in the spread of antibiotic-resistant opportunistic microorganisms causes serious problems in the treatment of purulent infections, burns, and trophic ulcers. We tested the antimicrobial activity in vivo of three polyphenols, Resveratrol, Dihydroquercetin (Taxifolin), and Dihydromyricetin (Ampelopsin) from Norway spruce bark to promote the elimination of and from wounds. Purulent infection was modelled on wounds in rats infected with suspensions containing 10 CFU (colony-forming unit)/mL of pathogens.

A New Recombinant Strain of Yarrowia lipolytica Producing Encapsulated Phytase from Obesumbacterium proteus.

A new recombinant strain of Yarrowia lipolytica synthesizing encapsulated highly thermostable phytase of Obesumbacterium proteus, which is recommended for use as a premix component of feed compositions in animal husbandry, was obtained.

Hepatitis E virus infection in different groups of Estonian patients and people who inject drugs.

Background: Previously we demonstrated a high prevalence of hepatitis E virus (HEV) in domestic pigs and wild boars, the main reservoir and possible source of HEV infections in humans. But so far there are no reports about spread of HEV in Estonian human population.

Objectives: The present study aimed to determine the prevalence and genotyping of HEV in different groups of the Estonian adult population.

Immunomodulating and Revascularizing Activity of Synergize with Fungicide Activity of Biogenic Peptide Cecropin P1.

Previously transgenic plants producing an antimicrobial peptide cecropin P1 (CecP1) have been reported. Now we report biological testing extracts containing CecP1 as a candidate drug for treatment of wounds infected with The drug constitutes the whole juice from leaves (not ethanol extract) sterilized with nanofiltration. A microbicide activity of CecP1 against an animal fungal pathogen in vivo was demonstrated for the first time.

Bactericide, Immunomodulating, and Wound Healing Properties of Transgenic Synergize with Antimicrobial Peptide Cecropin P1 In Vivo.

Procedure of manufacturing water extracts containing cecropin P1 (CecP1) from the formerly described transgenic plants is established. It included incubation of leaves at +4°C for 7 days, mechanical homogenization of leaves using water as extraction solvent, and heating at +70°C for inactivating plant enzymes. Yield of CecP1 (after heating and sterilizing filtration) was 0.

Modified gene lacZ encoding β-galactosidase as efficient transcriptional reporter for the Yarrowia lipolytica yeast.

A modified variant of the β-galactosidase gene from Escherichia coli (lacZ) has been obtained. This was designed for building transcriptional reporter constructs, the product of which possesses a higher proteolytic resistance in the Yarrowia lipolytica yeasts. The study of the activity of mitochondrial voltagedependent porin (voltage-dependent anion channel, VDAC) showed a high efficiency of the reporter system based on the designed lacZ reporter compared to the wild-type lacZ gene.

[USE OF THE REAL-TIME PCR FOR STUDY OF THE PERIODONTAL MICROBIOME IN PATIENTS WITH COMBINED PATHOLOGY OF GASTRODUODENAL ZONE AND CHRONIC PERIODONTITIS].

The total of 54 patients with chronic periodontitis of different severity was tested using real-time PCR (Dentoflor kit). The group included 38 patients with chronic gastritis. For the first time, a higher prevalence of Treponema denticola in periodontium of males in comparison with females was demonstrated.

Quantitative PCR studies of Aggregatibacter actinomycetemcomitans and Treponema denticola/Tanerella forsythensis Complex as Etiological Factors of Chronic Periodontitis.

Real-time quantitative PCR (Dentofl or kit) was used to detect DNA of periodontal pathogens in specimens from 92 patients with chronic periodontitis and from a control sample of 12 normal subjects. A bimodal distribution of patients by periodontium colonization with A. actinomycetemcomitans, P.

[Redox Status of Extremophilic Yeast Yarrowia Lipolytica During Adaptation to pH-Stress].

In this study we investigated the activities of antioxidant enzymes (superoxide dismutases (SODs) and catalases (CATs)) and the ROS level in cells of Yarrowia lipolytica yeasts grown in a medium with different pH values (4.5, 5.5 and 9.

[The Engineering of a Yarrowia lipolytica Yeast Strain Capable of Homologous Recombination of the Mitochondrial Genome].

None of the studied eukaryotic species has a natural system for homologous recombination of the mitochondrial genome. We propose an integrated genetic construct pQ-SRUS, which allows introduction of the recA gene from Bacillus subtilis into the nuclear genome of an extremophilic yeast, Yarrowia lipolytica. The targeting of recombinant RecA to the yeast mitochondria is provided by leader sequences (5'-UTR and 3'-UTR) derived from the SOD2 gene mRNA, which exhibits affinity to the outer mitochondrial membrane and thus provides cotranslational transport of RecA to the inner space of the mitochondria.

[Identification of key markers of normal and pathogenic microbiota determining health of periodontium by NGS-sequencing 16S-rDNA libraries of periodontal swabs].

By using NGS-sequencing libraries of DNA from periodontal swabs with primers specific to V6 region of 16S rDNA prevalence of bacterial genera and species in periodontal microbiota of patients with aggressive periodontitis and healthy donors was analyzed. Six genera of putative periodontal protectors and eight periodontal pathogens were identified with respect to aggressive (but not chronic) periodontitis. Statistically relevant over-colonization by general Porphyromonas, Treponema, Synergistes, Tannerella, Filifactor, Ruminococcus, Parvimonas and Mycoplasma was found to be associated with the condition.
