АНАЛИЗ ХИМИЧЕСКОГО СОСТАВА ПРОДУКТОВ РАЗЛОЖЕНИЯ РОССИЙСКОГО ВЕЩЕСТВА VX В УСЛОВИЯХ КАТАЛИТИЧЕСКОГО МЕТАНОЛИЗА

Analytical platform for the testing new decontaminating formulations, involving identification of toxic destruction products and determination of the depth of decontamination under conditions mimicking real decontamination scenarios, was developed. The possibility of application of catalytic methanolysis for destruction of a highly toxic compound О-isobutyl S-[2-(N,N-diethylamino)ethyl] methylphosphonothioate referred to Russian VX (hereinafter, RVX) in homogeneous and heterogeneous reaction media are studied. Conditions for extraction of residual RVX from the reaction mixture, as well as GC−MS analysis of RVX were found and optimized.  Destruction products of RVX, formed by its La-catalyzed methanolysis were identified. Efficiency of the catalytic formulation for decontamination of RVX-contaminated plastic surfaces was studied. The obtained results provide evidence for a high efficiency of the catalytic methanolysis for chemical neutralization of RVX and allow this process to be recommended for decontamination of engineering equipment.Key words:  toxic organophosphorus compounds, VX-group compounds, catalytic methanolysis, gas chromatography−mass spectrometry, decontamination(Russian)L.K.

Clinical anatomy features of the buccal part of the facial vein.

Abstract. Surgical interventions such as bishectomy or the oroantral fis�sure closure using the buccal extension of the buccal fat pad performed with transoral incision, which is associated with a significant number of risks. These risks include damaging of the facial vein and there is no in�formation its relationships with the fat body of the cheek in literature. The aim of the study is to describe the features of the clinical anatomy of the buccal part of the facial vein and its relationships with the buc�cal extention of the buccal fat pad. Materials and methods. We used 30 fresh cadavers heads, 15 both males and females. Vessels been filled with silicone compound according to the M. Landofi method. Topo�graphic and anatomical study was performed by layer-by-layer dissection on each side, so the total number of observations was 60. The relation of the facial vein to the facial artery, buccal fat pad and buccal muscle were described. Dissection results were photographed and recorded. Results. The facial vein was founded in 82% (n=49) cases. Were found 3 types of the relationship between the facial vein and the buccal fat pad. In the first type (58%; n=35), the facial vein passes through the buccal region between the outer surface of the buccal muscle and the buccal extension of the buccal fat pad. In the second type (15%; n=9), the fa�cial vein lies on the surface of the buccal muscle anteriorly to the buc�cal fat pad. The third type (8%; n=5) — the facial vein lies superficially, outward from the buccal fat pad. In most cases the combined weight of 1 and 2 types of the facial vein relationships was 73% (n=44), the fa�cial vein in the buccal region lies in the space between the buccal fat pad and the buccal muscle, crossing the most common horizontal inci�sions. Conclusions. The different types of the facial vein and buccal fat pad relationships should be taken into account as a potential risk factor during planning surgical interventions. Since in most cases the course of the facial vein crossing with the direction of the most common sur�gical incision, it is necessary to look for other safer options for surgical access to the buccal fat pad

Features of Femtosecond Correction of High Myopia through Small Access

Aim. To modify the calculated parameters of the lenticle extraction refractive surgery through a small access (SMILE), evaluate its safety and clinical efficacy in correcting high myopia.Materials and methods. 34 patients (68 eyes) underwent surgery by a modified SMILE technology under local anesthesia. In all cases, the patients had a high degree of myopia, in 37 % in combination with astigmatism.Uncorrected visual acuity before surgery averaged 0.05 ± 0.11, best corrected visual acuity of 0.94 ± 0.1, the pre-operative spherical refraction component was –7.23 ± 0.75, the cylindrical component was –0.48 ± 0.59.During the operation, to obtain the maximum possible refraction result using the proposed method, the standard operation parameters were changed: the corneal flap thickness was reduced to 100 μm, the neural optical layer by 5 μm, the diameter of the optical zone depended on the residual cornea thickness, which should exceed 280–290 μm. Corneal access was increased by 15–20 degrees.Results. The next day after surgery, monocular uncorrected visual acuity in distance in 73 % of patients was 0.8 or higher, and in 41 % of cases it was equal to or exceeded 1.0. The spherical equivalent on the first day after surgery had a slight hypermetropic shift, which was completely leveled by the year of follow-up. During the surgical intervention and in the postoperative period, no complications were noted.Conclusion. Using the proposed algorithm for calculating the refractive effect of the operation SMILE with a high degree of myopia allows obtaining a high refractive effect and avoiding possible complications

Towards the matter of genetic consulting in various forms of congenital and hereditary eye diseases

Purpose. To evaluate the results in genetic consulting of patients with various forms of congenital and hereditary eyes pathology.Material and methods. The study is based on an analysis of results in genetic consulting and molecular genetic investigations of DNA samples of 18 patients: congenital corneal dystrophy (n=3); congenital cataract (n=11); Norrie disease (n = 4). All patients had a comprehensive ophthalmologic clinical and functional examination according to the forms of pathology. Geneticist physician conducted a genealogical analysis. A study of exons and flanking intronic regions was performed using methods of analysis of amplified fragment length polymorphism, restriction fragments and direct sequencing.Results. The clinical diagnosis of endothelial corneal dystrophy with autosomal recessive mode of inheritance using molecular genetic methods in 2 of the 3 cases was confirmed, and a de novo mutation in the gene SLC4A11 non-described previously was found. In the group with hereditary diseases the lens pathogenic mutations were detected in the GJA3 andGJA8 genes in 2 of 11 cases (18%). Pathogenic mutations in NDP gene were detected only in 2 of 4 family members studied, and its sibling proband, directed to the genetic analysis of patients with a clinical diagnosis Norrie disease. In another of the studied probands the diseasecausing mutation was not reveled, and thus, the molecular genetic diagnosis of Norrie disease was not confirmed.Conclusion. For the first time in the Russian Federation pathogenic mutations in the gene SLC4A11 collagen, previously did not described in the literature, were revealed in patients with congenital endothelial corneal dystrophy, in a patient with congenital cataract in the gene GJA8. The success of genetic consulting depends on the complete genealogical analysis, and the correct determination of the clinical and genetic form of pathology
