    Get PDF
    The formation of paramagnetic centers in potassium picrate under irradiation at low temperature was investigated. The heating irradiated at 77 K potassium picrate crystal to room temperature results in paramagnetic centers - 2,6-dinitro-para-quinone radicals, ortho- and para-iminoxyl radicals and atomic oxygen. These products are formed under irradiation at room temperature

    The Study of Radiolysis of Ba(NO[3])[2] by ESR

    Get PDF
    Irradiation of Ba(NO[3])[2] [gamma]-rays at 308 K at increasing absorbed dose creates several new PC: 1, 2, 3, X. All of these are characterized by almost isotropic g-factor. Comparison of the observed parameters with literature data allows us to identify the PC as follows: 1 - O[3]{-}, 2 -O{-}. PC 3 and X presumably attributed to the complex centers [NO[2]...O[2]] or [NO[2]{-}...O{-}...O[2]]and [O{-}...O[2]], respectively

    Aim. This paper aims to examine the state of the renal blood circulation in patients with purulent pyelonephritis and to improve the quality of treatment through the use of our own technique.Materials and methods. The author personally examined and operated on 30 patients with confirmed purulent pyelonephritis in the conditions of a urology department at the regional clinical hospital. The author used his own method of treatment. A retroperitoneoscopic decapsulation of the affected kidney was performed on all the patients within the first 24 hours; this was combined with continuous regional arterial infusion of alprostadil within the next 72 hours. All the patients prior to surgery had undergone the following diagnostic procedures: general clinical examination, bolus contrast-enhanced MSCT of kidneys, renal duplex ultrasound, morphology examination.Results and discussion. The postoperative period in all the cases was good with the reduced number of days needed for treatment. On the first day after operation, the patients noted a reduction in the pain intensity in the affected side. The bolus contrast-enhanced MSCT imaging of kidneys in comparison to the data obtained prior to treatment demonstrates the disappearance of the destruction foci in the kidney and a clearly visible restored blood circulation in the affected side achieved rather fast. No patient required a nephrectomy.Conclusion. Every stage of the proposed treatment technique is an inalienable part of the method as a whole. Every stage is necessary to deliver the impact on its level of circulation, on the parenchyma affected by microabscesses, and on the infected areas. The method makes it possible to restore blood flow in the kidney and open up a path for the delivery of antibiotics into the organ parenchyma.Π’Π²Π΅Π΄Π΅Π½ΠΈΠ΅.

    Background. Modern minimally invasive surgical techniques reduce traumatism of operative interventions and aggressive anaesthesia, which accordingly shortens the patient’s hospital stay and rehabilitation period.Aim. An improvement of surgical outcomes in patients with purulent pyelonephritis via introduction of laparoscopic techniques.Materials and methods. Th e study included 80 purulent pyelonephritis patients operated at the Territorial Clinical Hospital during 2006β€”2018. Th e patients were divided between two cohorts. Cohort 1 included 40 (50Β %) patients operated with standard techniques (ST), cohort 2 β€” 40 (50Β %) patients having surgery by an original minimally invasive technique (OT). Kidney decapsulation was found to outcome in parenchymal decompression and blood circulation restore in cortical layer. Intraarterial infusion of alprostadil prevents further spread of purulent-destructive processes in kidney.Results and discussion. In patients with the minimally invasive technique, postoperative period proceeded at no complications. On day 1, the patients reported reduced pain syndrome in the surgical area. Contrasted renal MSCT before and aft er surgery showed the recovery of renal blood flow and significant diminishing of destruction foci in short term. Nephrectomy was not performed as no-indication.Conclusion. The treatment outcomes in 40 patients having the new surgical technique demonstrate its efficacy and applicability in clinical practice.Π’Π²Π΅Π΄Π΅Π½ΠΈΠ΅.

    Search of Axions from a Nuclear Power Reactor with a High-Purity Germanium Detector

    Full text link
    A search of axions produced in nuclear transitions was performed at the Kuo-Sheng Nuclear Power Station with a high-purity germanium detector of mass 1.06 kg at a distance of 28 m from the 2.9 GW reactor core. The expected experimental signatures were mono-energetic lines produced by their Primakoff or Compton conversions at the detector. Based on 459.0/96.3 days of Reactor ON/OFF data, no evidence of axion emissions were observed and constraints on the couplings \gagg and \gaee versus axion mass mam_a within the framework of invisible axion models were placed. The KSVZ and DFSZ models can be excluded for 10^4 eV < m_a < 10^6 ~eV. Model-independent constraints on \gagg \gv1 < 7.7 X 10^{-9} GeV^{-2} for m_{a} < 10^5 eV and \gaee \gv1 < 1.3 X 10^{-10} for m_{a} < 10^6 eV at 90% confidence level were derived. This experimental approach provides a unique probe for axion mass at the keV--MeV range not accessible to the other techniques.Comment: 9 pages, 4 tables, 8 figures, V2: major expansion from V

    Predictors of atrial fibrillation recurrence in patients with metabolic syndrome after pulmonary vein isolation

    Get PDF
    Aim. To determine the role of biomarkers in predicting atrial fibrillation (AF) recurrence within 12 months after radiofrequency ablation (RFA) in patients with metabolic syndrome (MS).Material and methods. The study included 245 patients with AF aged 35 to 65 years: patients without MS components (n=32), with 1-2 MS components (n=62) and patients with 3 or more MS components (n=153). All patients underwent a comprehensive clinical and anamnestic, anthropometric, laboratory and echocardiographic examinations. The prospective follow-up for 12 months included 135 patients with AF who underwent RFA.Results. It was found that the presence of 3 or more MS components increased the risk of AF recurrence by 4,1 times within 12 months after RFA (relative risk (RR) =4,1, 95% CI 2,19-7,65, p&lt;0,0001). According to binomial logistic regression, epicardial fat thickness (EFT) (OR =3,71, 95% CI 2,12-6,73, p=0,00001), the severity of left atrial fibrosis (OR =1,48, 95% CI 1,03-1,78, p=0,0006), concentrations of galectin-3 (OR =1,31, 95% CI 1,12-1,51, p=0,0001) and GDF-15 (OR =1,11, 95% CI 1,02-1,18, p=0,0002) in patients with AF and MS increase the risk of AF recurrence after RFA. For galectin-3, GDF-15, and EFT, using ROC analysis, the following threshold values were established, the excess of which had the greatest effect on the risk of AF recurrence after RFA in patients with MS: galectin-3 &gt;11,0 ng/ml (RR =3,43, 95% CI 1,79-6,58, p=0,0001), GDF-15 &gt;1380,7 pg/ml (RR =2,84, 95% CI 1,81-4,46, p&lt;0,0001) and EFT &gt;6,4 mm (RR =4,50, 95% CI 2,32-8,71, p&lt;0,0001). In patients with excess of all three biomarker thresholds, the total risk of AF recurrence in patients with MS within 12 months after RFA increases by 3,2 times (RR =3,16, 95% CI 1,97-5,11, p&lt;0,00001).Conclusion. The risk of AF recurrence within 12 months after RFA in patients with three or more MS components is higher than in patients with 1-2 MS components. An increase in the blood concentration of profibrogenic biomarkers galectin-3, GDF-15 and an increase in the thickness of epicardial adipose tissue is associated with an increased risk of AF recurrence in patients with MS, and these biomarkers are likely to play a significant role in predicting recurrent episodes of AF after RFA
