The main aim of the research is to study the mineralogical and geochemical features and determine the origin of luminescent layers in the deposits of the Bazhenov formation. Objects: sedimentary rocks, luminescent layers and enclosing rocks of the Bazhenov formation. Methods: X-ray diffractometry, petrographic analysis, scanning electron microscopy, inductively coupled plasma mass spectrometry, inductively coupled plasma atomic emission spectrometry, instrumental neutron activation analysis, X-ray luminescence. Results. The luminescent layers in ultraviolet light were detected in the distribution area of the Bazhenov formation in the central and south-eastern part of the West Siberian sedimentary basin. Thickness of layers varies from 2 mm to 15 cm. The study of the mineral composition made it possible to divide the separated layers into two groups according to the main mineral phases. The study of layers of the I group showed that they are composed mainly of clay minerals with an admixture of clastic silty material. The main clay minerals in them are kaolinite and mixed-layer minerals of the illite-smectite series. Layers with a predominantly siliceous (quartz) composition correspond to the II group. When analyzing chemical composition data it was identified that the studied layers as a whole have lower element contents (Co, Ni, Cu, Zn, Moand others) compared to the "ordinary" rocks of the Bazhenov formation due to the low content of buried organic matter, which is traditionally associated with the accumulation of some microelements. The elevated concentrations of thorium in the samples of the studied layers are noted. The study shown the signs of the presence of volcanic material. It is assumed that the studied layers are of volcanic origin and were formed as a result of the dia- and catagenetic transformation of the volcanoclastic material of tuff sediments in the presence of a large amount of organic matter
Different impact of sex on baseline characteristics and major periprocedural outcomes of transcatheter and surgical aortic valve interventions: results of the multicenter Italian OBSERVANT Registry
Background: Despite the widespread use of transcatheter aortic valve implantation (TAVI), the role of sex on outcome after TAVI or surgical aortic valve replacement (AVR) has been poorly investigated. We investigated the impact of sex on outcome after TAVI or AVR. Methods: There were 2108 patients undergoing TAVI or AVR who were enrolled in the Italian Observational Multicenter Registry (OBSERVANT). Thirty-day mortality, major periprocedural morbidity, and transprosthetic gradients were stratified by sex according to interventions. Results: Female AVR patients showed a worse risk profile compared with male AVR patients, given the higher mean age, prevalence of frailty score of 2 or higher, New York Heart Association class of 3 or higher, lower body weight, and preoperative hemoglobin level (P β€.02). Similarly, female TAVI patients had a different risk profile than male TAVI patients, given a higher age and a lower body weight and preoperative hemoglobin level (P β€.005), but with a similar New York Heart Association class, frailty score, EuroSCORE (P = NS), a better left ventricular ejection fraction and a lower prevalence of left ventricular ejection fraction less than 30%, porcelain aorta, renal dysfunction, chronic obstructive pulmonary disease, arteriopathy, and previous cardiovascular surgery or percutaneous coronary intervention (P β€.01). Women showed a smaller aortic annulus than men in both populations (P <.001). Female sex was an independent predictor in the AVR population for risk-Adjusted 30-day mortality (odds ratio [OR], 2.34; P =.043) and transfusions (OR, 1.47; P =.003), but not for risk-Adjusted acute myocardial infarction, stroke, vascular complications, permanent atrioventricular block (P = NS). Female sex was an independent predictor in the TAVI population for risk-Adjusted major vascular complications (OR, 2.92; P =.018) and transfusions (OR, 1.93; P =.003), but proved protective against moderate to severe postprocedural aortic insufficiency (P =.018). Conclusions: Female sex is a risk factor for mortality after aortic valve replacement, for major vascular complications after TAVI, and for transfusions after both approaches.
