    A statisticalΒ  analysis of position and mobility of the diaphragmΒ  in adults with normal lung function is not operated and underwent various cardiac interventions. The study included 2441 the patient,Β  divided into groups non-operated and undergoingΒ  various cardiac surgical intervention.Β  Were determinedΒ  the mean values of the position and mobility of the diaphragm,Β  the frequency of elevation and diaphragm dysfunction. Using ROC analysis establishedΒ  the degree of influence for the elevation and dysfunction of the diaphragm of the body mass index (BMI), the coefficient of mobility of the diaphragmΒ  (CMD)Β  and indicatorsΒ  of the position of the domes of the diaphragm.Β  It is revealed that after cardiac operationsΒ  the position of the domes of the diaphragm was higher and decreasedΒ  mobility of the diaphragm. Elevation and dysfunction among non-operated diaphragm was noted in a few cases, and after cardiac surgery significantly more often. Non-operated patientsΒ  have a statisticallyΒ  significant impact on elevation of the right dome had a value of (AUC 0,99) and the elevation of the left dome of the diaphragm the magnitudeΒ  of BMI (AUC of 0,89). They have not identified effects on diaphragmaticΒ  dysfunction none of the studied factors. In postoperativeΒ  patients, the rates of mobility of the diaphragm showed a good effect on the elevation (AUC of 0,84–0,86), while the value of BMI showed an average quality of effects in all models (AUC of 0,62 to 0,65). A statistically significant effect on diaphragm matic dysfunction provided only the position of the domes of the diaphragm (AUC 0,78–0,83). Patients undergoing different cardiac surgical intervention have a statistically significant decrease of mobility and increase the position of the diaphragm,Β  increasing the frequency of elevation and dysfunction. From non-operated patientsΒ  on the mobility of the diaphragm did not affect any height standingΒ  domes of the diaphragm or BMI. On the position of the right dome affects only the rate of mobility of the diaphragm, and the left dome β€” the value of BMI. Patients after various cardiac surgeriesΒ  greaterΒ  impact on the elevation of the diaphragm provided an indicator of its mobility, than BMI and dysfunction of the diaphragm affects only its position.ΠŸΡ€ΠΎΠ²Π΅Π΄Π΅Π½ статистичСский Π°Π½Π°Π»ΠΈΠ· полоТСния ΠΈ подвиТности Π΄ΠΈΠ°Ρ„Ρ€Π°Π³ΠΌΡ‹ Ρƒ взрослых с Π½ΠΎΡ€ΠΌΠ°Π»ΡŒΠ½ΠΎΠΉ Ρ„ΡƒΠ½ΠΊΡ†ΠΈΠ΅ΠΉ Π»Π΅Π³ΠΊΠΈΡ…, готовящихся ΠΊ опСрациям ΠΈ послС Ρ€Π°Π·Π»ΠΈΡ‡Π½Ρ‹Ρ… кардиохирургичСских Π²ΠΌΠ΅ΡˆΠ°Ρ‚Π΅Π»ΡŒΡΡ‚Π².

    Background. Giant coronary artery aneurysms are extremely rare findings. According to foreign authors, their prevalence as a result of autopsy ranged from 0.02 to 0.2%. Most often, they do not have specific symptoms and are detected after the development of complications, such as acute coronary syndrome, myocardial infarction. The risk of sudden complications causes an unfavorable prognosis of the disease and requires immediate surgical correction.Aim: to demonstrate the effectiveness of radiology methods in assessing coronary anatomy and the possibility of visualization before planning surgery.Materials and methods. The patient was referred to the Federal State Budgetary Institution β€œFCCVS” of the Ministry of Health of Russia (Penza) for additional examination and surgical treatment. Before surgery, to clarify the features of the macromorphology of the aneurysm, selective coronary angiography and CT coronary angiography were performed.Results. Before surgery, according to CT coronary angiography, a partially thrombosed fusiform aneurysm was detected in the anterior descending artery with a maximum size of 7.0 x 3.5 cm, adjacent to the pulmonary artery trunk and left atrial appendage.Conclusion. In modern conditions, the methods of radiology are successfully used to clarify the localization of aneurysms and individual topographic and anatomical features of the coronary arteries.ΠΠΊΡ‚ΡƒΠ°Π»ΡŒΠ½ΠΎΡΡ‚ΡŒ: гигантскиС Π°Π½Π΅Π²Ρ€ΠΈΠ·ΠΌΡ‹ ΠΊΠΎΡ€ΠΎΠ½Π°Ρ€Π½Ρ‹Ρ… Π°Ρ€Ρ‚Π΅Ρ€ΠΈΠΉ ΡΠ²Π»ΡΡŽΡ‚ΡΡ Ρ‡Ρ€Π΅Π·Π²Ρ‹Ρ‡Π°ΠΉΠ½ΠΎ Ρ€Π΅Π΄ΠΊΠΈΠΌΠΈ Π½Π°Ρ…ΠΎΠ΄ΠΊΠ°ΠΌΠΈ.

    This paper reports the results of a mineralogical study of 14 mantle peridotite samples dredged in 2009 from the eastern slope of the northwestern segment of the Stalemate Ridge in the northwestern Pacific during cruise SO201-KALMAR Leg 1b of the R/V Sonne. The sample collection included four serpentinized and silicified dunites and ten variably serpentinized lherzolites. The compositions of primary minerals (clinopyroxene, orthopyroxene, and spinel) change systematically from the lherzolites to dunites. Spinel from the lherzolites shows higher Mg# and lower Cr# values (0.65-0.68 and 0.26-0.33, respectively) compared with spinel from the dunites (Mg# = 0.56-0.64 and Cr# = 0.38-0.43). Clinopyroxene from the lherzolites is less magnesian (Mg# = 91.7-92.4) than clinopyroxene from dunite sample DR37-3 (Mg# = 93.7). Based on the obtained data, it was concluded that the lherzolites of the Stalemate Fracture Zone were derived by 10-12% near-fractional melting of a DMM-type depleted mantle reservoir beneath the Kula-Pacific spreading center. The dunites were produced by interaction of residual lherzolites with sodium- and titaniumrich melt and are probably fragments of a network of dunite channels in the shallow mantle. The moderately depleted composition of minerals clearly distinguishes the lherzolites from the strongly depleted peridotites of the East Pacific Rise and indicates the existence of slow-spreading mid-ocean ridges in the Pacific Ocean during the Cretaceous-Paleogene

    Relevance. The choice of perfusion strategy is vital for the protection of internal organs during surgery. In several studies of recent years, as well as by us, a strategy of sustained total all region (STAR) perfusion (selective brain, heart and lower body perfusion) has been proposed, allowing to avoid ischemic and reperfusion injuries of internal organs.The objective was to evaluate the benefits of STAR perfusion during reconstruction of the aortic arch in children.Materials and methods. The prospective study included 15 patients who underwent aortic arch reconstruction using a strategy of simultaneous selective brain, heart and lower body perfusion (STAR perfusion) in the period from June 2022 to May 2023. The average age at the time of surgery was 1.3 months (95 % CI (confidence interval) 6.0–16.0), the average body weight was 3.4 kg (95 % CI 2.7–4.1).Results. Π‘hanges of the tissue oximetry index, measured at two points, did not fall below reference ranges at any stage of the operation. The greatest mean value of lactate concentration during the operation was 2.8 Β± 1.0 mmol/l, recovery of the indicator was noted after 6 hours – 1.9 Β± 0.9 mmol/l. Kidney function evaluation – the rate of diuresis and creatinine levels did not exceed reference levels. The average treatment time in the intensive care unit was 7.7 Β± 4.3 days (95 % CI 4.5 10.9), in the hospital – 15.4 Β± 5.8 days (95 % CI 11.4–19.4). There were no deaths among those operated using the new perfusion strategy.Conclusion. The use of the strategy of Sustained Total All Region (STAR) perfusion in case of reconstruction of the aortic arch in newborn, infants and young children is safe and advanced, since it avoids ischemia of internal organs and reduces the risk of post-ischemic complications.ΠΠΊΡ‚ΡƒΠ°Π»ΡŒΠ½ΠΎΡΡ‚ΡŒ.

    Production of {\pi}+ and K+ mesons in argon-nucleus interactions at 3.2 AGeV

    Full text link
    First physics results of the BM@N experiment at the Nuclotron/NICA complex are presented on {\pi}+ and K+ meson production in interactions of an argon beam with fixed targets of C, Al, Cu, Sn and Pb at 3.2 AGeV. Transverse momentum distributions, rapidity spectra and multiplicities of {\pi}+ and K+ mesons are measured. The results are compared with predictions of theoretical models and with other measurements at lower energies.Comment: 29 pages, 20 figure

    Comparisons between Tethyan Anorthosite-bearing Ophiolites and Archean Anorthosite-bearing Layered Intrusions: Implications for Archean Geodynamic Processes

    Elucidating the petrogenesis and geodynamic setting(s) of anorthosites in Archean layered intrusions and Tethyan ophiolites has significant implications for crustal evolution and growth throughout Earth history. Archean anorthosite-bearing layered intrusions occur on every continent. Tethyan ophiolites occur in Europe, Africa, and Asia. In this contribution, the field, petrographic, petrological, and geochemical characteristics of 100 Tethyan anorthosite-bearing ophiolites and 155 Archean anorthosite-bearing layered intrusions are compared. Tethyan anorthosite-bearing ophiolites range from Devonian to Paleocene in age, are variably composite, contain anorthosites with highly calcic (An44-100) plagioclase and magmatic amphibole. These ophiolites formed predominantly at convergent plate margins, with some forming in mid-ocean ridge, continental rift, and mantle plume settings. The predominantly convergent plate margin tectonic setting of Tethyan anorthosite-bearing ophiolites is indicated by negative Nb and Ti anomalies and magmatic amphibole. Archean anorthosite-bearing layered intrusions are Eoarchean to Neoarchean in age, have megacrystic anorthosites with highly calcic (An20-100) plagioclase and magmatic amphibole and are interlayered with gabbros and leucogabbros and intrude pillow basalts. These Archean layered intrusions are interpreted to have predominantly formed at convergent plate margins, with the remainder forming in mantle plume, continental rift, oceanic plateau, post-orogenic, anorogenic, mid-ocean ridge, and passive continental margin settings. These layered intrusions predominantly crystallized from hydrous Ca- and Al-rich tholeiitic magmas. The field, petrographic and geochemical similarities between Archean and Tethyan anorthosites indicate that they were produced by similar geodynamic processes mainly in suprasubduction zone settings. We suggest that Archean anorthosite-bearing layered intrusions and spatially associated greenstone belts represent dismembered subduction-related Archean ophiolites

    Model for screening of resonant magnetic perturbations by plasma in a realistic tokamak geometry and its impact on divertor strike points

    Full text link
    This work addresses the question of the relation between strike-point splitting and magnetic stochasticity at the edge of a poloidally diverted tokamak in the presence of externally imposed magnetic perturbations. More specifically, ad-hoc helical current sheets are introduced in order to mimic a hypothetical screening of the external resonant magnetic perturbations by the plasma. These current sheets, which suppress magnetic islands, are found to reduce the amount of splitting expected at the target, which suggests that screening effects should be observable experimentally. Multiple screening current sheets reinforce each other, i.e. less current relative to the case of only one current sheet is required to screen the perturbation.Comment: Accepted in the Proceedings of the 19th International Conference on Plasma Surface Interactions, to be published in Journal of Nuclear Materials.
