Isolation of a wide range of minerals from a thermally treated plant: Equisetum arvense, a Mare’s tale

Silica is the second most abundant biomineral being exceeded in nature only by biogenic CaCO3. Many land plants (such as rice, cereals, cucumber, etc.) deposit silica in significant amounts to reinforce their tissues and as a systematic response to pathogen attack. One of the most ancient species of living vascular plants, Equisetum arvense is also able to take up and accumulate silica in all parts of the plant. Numerous methods have been developed for elimination of the organic material and/or metal ions present in plant material to isolate biogenic silica. However, depending on the chemical and/or physical treatment applied to branch or stem from Equisetum arvense; other mineral forms such glass-type materials (i.e. CaSiO3), salts (i.e. KCl) or luminescent materials can also be isolated from the plant material. In the current contribution, we show the chemical and/or thermal routes that lead to the formation of a number of different mineral types in addition to biogenic silica

Effectiveness evaluation of application of niosomal gel "Regenerin" in the treatment of chemical burns of cornea

The aim of the work was to study the effectiveness of using the ophthalmic gel "Regenerin" in the treatment of a simulated chemical burn of the cornea in an experiment. Material and Methods. The chemical composition of the drug "Regenerin" was studied by mass spectrometry The regenerative action of the niosomal gel, including low molecular weight peptides extracted from placental cells and encapsulated, was then studied in 40 organisms of 20 rabbits of the chinchilla breed with a 10% solution of caustic soda. The subjects of the study are divided equally into two groups: in the experimental group, the treatment was carried out by applying a gel to the burn surface, the therapy was not performed in the control group. Results. The result of treatment with the "Regenerin" Ophthalmic Gel is a significant reduction in the timing of reparative regeneration in the animals of the experimental group due to increased metabolism and corneal neovascularization processes. Conclusion. The combined effect of these mechanisms, manifested in the arrest of edema, resorption of inflammatory infiltrates, normalization of the integrity of the endothelium, epithelial layer and basal membrane leads to completely restoring the histological structure of the cornea on the seventh day.</p

Phenotypic Peculiarities of Pathogenic <i>Burkholderia</i> Mutants Resistant to Fluoroquinolones and Cephalosporins

Examined were phenotypic peculiarities of mutants of Burkholderia phylogenetically-related pathogenic species (B. pseudomallei, B. mallei, B. cepacia) resistant to fluoroquinolones and cephalosporins. It was shown that strains with PfxR (OfxR), CfzR markers acquire high multi-drug resistance to antibiotics of different classes. Strain resistance changes under blocking influence of verapamil - inhibitor of calcium membrane channels. Mutant strains differ in production of extracellular enzymes (proteases, lecithinase, lipase) and virulence

Validation of the modified Rankin Scale in Russia

Objective: to develop a Russian version of the modified Rankin Scale (mRS) and to assess its psychometric properties.Patients and methods. The investigation involved 50 patients (25 women, 25 men) over 18 years of age (mean age, 56 years) with an acute cerebrovascular accident diagnosis. During the validation procedure, the authors carried out the linguocultural ratification of mRS, prepared its Russian-language version, and then assessed its psychometric properties (reliability, sensitivity, validity).Results and discussion. Translation and linguistic adaptation of mRS was successfully completed. The results obtained in assessing the psychometric properties of the developed Russian version of the scale reflect its high reliability and the valid and reliable indicators of its sensitivity. A statistical study of constructive and content validity also determined the high significance of differences.Conclusion. The investigation has resulted in the official Russian version of mRS, which is recommended for use by neurologists and rehabilitation specialists in both daily clinical practice and in clinical trials

The Attitude of Pregnant Women and Health Workers for Influenza Vaccination

Influenza and ARVI - the main nosological form in structure of all infectious diseases. Influenza is especially dangerous to pregnant women. Purpose: to estimate commitment of pregnant women and health workers to vaccination against influenza. Materials and methods: form No. 5, form of the statistical account No. 1 - influenza the section 1, information from the official site of Federal State Budgetary Institution Scientific Research Institute of influenza of the Ministry of Health of the Russian Federation; materials of various conferences and the congresses on a influenza problem, information and analytical reference of the Ministry of Health of the Russian Federation. There were asked 1126 pregnant women on various durations of gestation and 447 health workers in various territories of the Russian Federation. Statistical processing was carried out with use of the Microsoft Excel 2010 and IBM SPSS Statistics 20.0 programs. Results and discussion: Among the interviewed pregnant women planned or were already vaccinated against influenza only 8% of women. The most frequent causes of failure from vaccination against influenza during pregnancy: doubt in safety (41.8%), ignorance about possibilities of vaccination (21,1%), lack of need for vaccination (18,7%). Only 25% of respondents knew about entering vaccination against influenza during pregnancy into a national calendar. At the same time only in 15% of health workers suggested pregnant women to be vaccinated from influenza. 73% of the interviewed health workers didn't recommend vaccination against influenza to pregnant women because they consider undesirable an intervention in immunity of the pregnant woman, 33% doubt in safety of vaccination, 13% don't know about a possibility of vaccination of pregnant women at all, 6% have personal negative experience of vaccination, and 4% don't see need for vaccination from influenza. Conclusion: the received materials showed need of development of knowledge at health workers of a vaccinal prevention of infectious diseases, including also vaccination against influenza during pregnancy, and also to carry out broad and active information work with the population, attracting mass media
