Abstract

We present updated results from the NOvA experiment for $\nu_\mu\rightarrow\nu_\mu$ and $\nu_\mu\rightarrow\nu_e$ oscillations from an exposure of $8.85\times10^{20}$ protons on target, which represents an increase of 46% compared to our previous publication. The results utilize significant improvements in both the simulations and analysis of the data. A joint fit to the data for $\nu_\mu$ disappearance and $\nu_e$ appearance gives the best fit point as normal mass hierarchy, $\Delta m^2_{32} = 2.44\times 10^{-3}{{\rm eV}^2}/c^4$, $\sin^2\theta_{23} = 0.56$, and $\delta_{CP} = 1.21\pi$. The 68.3% confidence intervals in the normal mass hierarchy are $\Delta m^2_{32} \in [2.37,2.52]\times 10^{-3}{{\rm eV}^2}/c^4$, $\sin^2\theta_{23} \in [0.43,0.51] \cup [0.52,0.60]$, and $\delta_{CP} \in [0,0.12\pi] \cup [0.91\pi,2\pi]$. The inverted mass hierarchy is disfavored at the 95% confidence level for all choices of the other oscillation parameters.

tetralogy of fallot, down syndrome, complete surgical correction, Medicine
Abstract

The tetralogy of Fallot is the most common form of cyanotic congenital heart malformations. However, its association with Down syndrome is uncommon. We present two patients with uncorrected during childhood tetralogy of Fallot. One of them had also Down syndrome. We performed a complete surgical correction: closure of the inter-ventricular defect, right ventricular outflow tract reconstruction, pulmonary valve prosthesis and pulmonary artery patch repair (in one of the cases). The postoperative period was uncomplicated, patients were discharged on days 12 and 10, and the follow-up showed a significant functional class improvement.

Abstract

We present a case of a biatrial thrombus penetrating through the PFO against the background of massive bilateral pulmonary thromboembolism in a 75-year-old patient. Because of the rare condition, there are no literature data on consensus treatment. Due to the patient’s clinical status and the results of the diagnostic tests, for the specific clinical case was made a decision for emergency surgical thrombectomy with PFO closure.

21. Non-invasive dissection of the human visual system

Abstract

A flickering stimulus can appear brighter or of different colour than a steady stimulus of the same spectral composition and equal time-averaged intensity. The change in appearance is consistent with the distortion product of a nonlinearity in the human visual system. This nonlinearity is used for non-invasive dissection of the human visual system into prenonlinearity and post-nonlinearity linear stages, which affect the amplitude of the sinusoidal signals that they process. A five-channel Maxwellian system was used to generate cosine-windowed, amplitude-modulated, sinusoidally-flickering stimuli. The subjects adjusted the maximum modulation of the signal in order to set the threshold for the perception of flicker and colour or brightness change. The pre-nonlinearity filter was tested by varying the carrier frequency between 5 Hz and 60 Hz and the post-nonlinearity filter was measured by varying the amplitude-modulation frequency between 0.25 Hz and 5 Hz. The L- and M-cone pathways are separately measured by using a new combination of the silent-cone-substitution technique and the sandwich model. The distortion product at the output of the nonlinearity is measured by using a new matching method for measuring the colour and brightness changes. The results suggest that the pre-nonlinearity filter is band-pass and shows substantial adaptation with light intensity that can explain most of the adaptation in the visual pathways. The post-nonlinearity filter is low-pass and shows little or no adaptation with light intensity. The input-output function of the nonlinearity can be described as an expansive, quadratic function that rapidly saturates at high input levels.

Abstract

Item does not contain fulltext, INTRODUCTION: Lipopolysaccharide (LPS) is the outer membrane component of Gram-negative bacteria. LPS-binding protein (LBP) is an acute-phase reactant that mediates immune responses triggered by LPS and has been used as a blood marker for LPS. LBP has recently been indicated to be associated with Parkinson's disease (PD) in small-scale retrospective case-control studies. We aimed to investigate the association between LBP blood levels with PD risk in a nested case-control study within a large European prospective cohort. METHODS: A total of 352 incident PD cases (55% males) were identified and one control per case was selected, matched by age at recruitment, sex and study center. LBP levels in plasma collected at recruitment, which was on average 7.8 years before diagnosis of the cases, were analyzed by enzyme linked immunosorbent assay. Odds ratios (ORs) were estimated for one unit increase of the natural log of LBP levels and PD incidence by conditional logistic regression. RESULTS: Plasma LBP levels were higher in prospective PD cases compared to controls (median (interquartile range) 26.9 (18.1-41.0) vs. 24.7 (16.6-38.4) µg/ml). The OR for PD incidence per one unit increase of log LBP was elevated (1.46, 95% CI 0.98-2.19). This association was more pronounced among women (OR 2.68, 95% CI 1.40-5.13) and overweight/obese subjects (OR 1.54, 95% CI 1.09-2.18). CONCLUSION: The findings suggest that higher plasma LBP levels may be associated with an increased risk of PD and may thus pinpoint to a potential role of endotoxemia in the pathogenesis of PD, particularly in women and overweight/obese individuals.

Abstract

BACKGROUND: End-stage renal disease is associated with a high risk of cardiovascular events. It is unknown, however, whether mild-to-moderate kidney dysfunction is causally related to coronary heart disease (CHD) and stroke. METHODS: Observational analyses were conducted using individual-level data from 4 population data sources (Emerging Risk Factors Collaboration, EPIC-CVD [European Prospective Investigation into Cancer and Nutrition-Cardiovascular Disease Study], Million Veteran Program, and UK Biobank), comprising 648 135 participants with no history of cardiovascular disease or diabetes at baseline, yielding 42 858 and 15 693 incident CHD and stroke events, respectively, during 6.8 million person-years of follow-up. Using a genetic risk score of 218 variants for estimated glomerular filtration rate (eGFR), we conducted Mendelian randomization analyses involving 413 718 participants (25 917 CHD and 8622 strokes) in EPIC-CVD, Million Veteran Program, and UK Biobank. RESULTS: There were U-shaped observational associations of creatinine-based eGFR with CHD and stroke, with higher risk in participants with eGFR values <60 or >105 mL·min-1·1.73 m-2, compared with those with eGFR between 60 and 105 mL·min-1·1.73 m-2. Mendelian randomization analyses for CHD showed an association among participants with eGFR <60 mL·min-1·1.73 m-2, with a 14% (95% CI, 3%-27%) higher CHD risk per 5 mL·min-1·1.73 m-2 lower genetically predicted eGFR, but not for those with eGFR >105 mL·min-1·1.73 m-2. Results were not materially different after adjustment for factors associated with the eGFR genetic risk score, such as lipoprotein(a), triglycerides, hemoglobin A1c, and blood pressure. Mendelian randomization results for stroke were nonsignificant but broadly similar to those for CHD. CONCLUSIONS: In people without manifest cardiovascular disease or diabetes, mild-to-moderate kidney dysfunction is causally related to risk of CHD, highlighting the potential value of preventive approaches th
