Statistics of Neutron Stars at the Stage of Supersonic Propeller

We analyze the statistical distribution of neutron stars at the stage of a supersonic propeller. An important point of our analysis is allowance for the evolution of the angle of inclination of the magnetic axis to the spin axis of the neutron star for the boundary of the transition to the supersonic propeller stage for two models: the model with hindered particle escape from the stellar surface and the model with free particle escape. As a result, we have shown that a consistent allowance for the evolution of the inclination angle in the region of extinct radio pulsars for the two models leads to an increase in the total number of neutron stars at the supersonic propeller stage. This increase stems from he fact that when allowing for the evolution of the inclination angle $\chi$ for neutron stars in the region of extinct radio pulsars and, hence, for the boundary of the transition to the propeller stage, this transition is possible at shorter spin periods (P~5-10 s) than assumed in the standard model.Comment: 15 pages, 6 figures; scale corrected for figures 3-

Therapy of Schizoaffective Disorder and Paranoid Schizophrenia with Episodic Course

Background. The use of atypical antipsychotics in schizophrenia contributes to the reduction of psychotic, affective, negative and cognitive disorders.Aims. To evaluate the effectiveness of ziprasidone therapy in patients with schizoaffective disorder and paranoid schizophrenia with episodic course.Materials and methods. In accordance with ICD-10 there were 14 (63.6 %) people with schizoaffective disorder (F25), 8 (36.4 %) people with paranoid schizophrenia, episodic course (F20.x1). Treatment with ziprasidone lasted 42 days. The dose of ziprasidone in 6 patients (27.3 %) was 80 mg, in 10 patients (45.5 %) – 120 mg, in 6 patients (27.3 %) – 160 mg. Evaluation of the effectiveness of ziprasidone therapy was carried out using psychometric scales (PANSS, General clinical impression scale to assess the effectiveness of therapy – CGI-S, CGI-I), adverse events were registered with the UKU scale.Results. The number of respondents was 19 (86.3 %) (reduction of the total score on the PANSS scale > 20 % of the pre-treatment level). Ziprasidone was effective in patients with schizoaffective disorder with a significant decrease in total score on PANSS subscales to the 14 th day of therapy (p < 0.05), with paranoid schizophrenia with episodic course – by the 21st day (p < 0.01). According to the CGI-S scale at the end of therapy, “borderline condition” was observed in 10 patients (52.6 %), mild severity – in 3 (15.8 %), normal condition – in 6 (31.6 %). CGI-I scale showed a significant improvement in 10 patients (52.6 %), marked improvement – in 9 patients (47.4 %). Among the mild adverse events that do not require discontinuation of the drug, we noted: weakness – in 3 patients (15.8 %), drowsiness – in 3 (15.8 %), impaired concentration – in 2 (10.5 %), orthostatic dizziness – in 2 (10.5 %), galactorrhea – in 1 (5.3 %).Conclusions. Ziprasidone is an effective antipsychotic drug that has a safe tolerability profile. It can be used in patients with schizoaffective disorders and paranoid schizophrenia with episodic course

Structural and Luminescence Properties of Silica-Based Hybrids Containing New Silylated-Diketonato Europium(III) Complex

A new betadiketonate ligand displaying a trimethoxysilyl group as grafting function and a diketone moiety as complexing site (TTA-Si = 4,4,4-trifluoro-2-(3-trimethoxysilyl)propyl)-1-3-butanedione (C4H3S)COCH[(CH2)3Si(OCH3)3]COCF3) and its highly luminescent europium(III) complex [Eu(TTA-Si)3] have been synthesized and fully characterized. Luminescent silica-based hybrids have been prepared as well with this new complex grafted on the surface of dense silica nanoparticles (28 (+/-3 nm) or on mesoporous silica particles. The covalent bonding of Eu(TTA-Si)3 inside the core of uniform silica nanoparticles (40 (+/- 5 nm) was also achieved. Luminescence properties are discussed in relation to the europium chemical environment involved in each of the three hybrids. The general methodology proposed allowed high grafting ratios and overcame chelate release and tendency to agglomeration, and it could be applied to any silica matrix (in the core or at the surface, nanosized or not, dense or mesoporous) and therefore numerous applications such as luminescent markers and luminophors could be foreseen

The role of the ultrasound examination of the brachial plexus in thoracic outlet syndrome

Introduction. Difficulties in determining the compression of the neurovascular bundle with the thoracic outlet syndrome raises the question of finding an accessible and reproducible method for the neuroimaging of the brachial plexus and surrounding tissues.Purpose of the study – to develop an ultrasound diagnostic algorithm using a stress test to determine the level and cause of brachial plexus compression in comparison with the results of a clinical assessment.Materials and methods. 111 patients with verified compression of the brachial plexus at the level of the interstitial (65.7 %) and bone-clavicular space (21.6 %), as well as the tendon of the pectoralis minor muscle (12.6 %) were examined. The study protocol including the Adson ultrasound stress test, the assessment of the lower trunk in the interstitial space, and the test with ultrasound evaluation of the axillary artery at the level of the tendon of the pectoralis minor muscle with passive abduction of the arm back and up was used.Conclusion. An ultrasound study of the brachial plexus demonstrated informativeness in assessing the level and possible cause of compression, which opens up the possibility of using the method in routine neurological practice

Relationship of the Content of Systemic and Endobronchial Soluble Molecules of CD25, CD38, CD8, and HLA-I-CD8 and Lung Function Parameters in COPD Patients

© 2017 Nailya Kubysheva et al. The definition of new markers of local and systemic inflammation of chronic obstructive pulmonary disease (COPD) is one of the priority directions in the study of pathogenesis and diagnostic methods improvement for this disease. We investigated 91 patients with COPD and 21 healthy nonsmokers. The levels of soluble CD25, CD38, CD8, and HLA-I-CD8 molecules in the blood serum and exhaled breath condensate (EBC) in moderate-to-severe COPD patients during exacerbation and stable phase were studied. An unidirectional change in the content of sCD25, sCD38, and sCD8 molecules with increasing severity of COPD was detected. The correlations between the parameters of lung function and sCD8, sCD25, and sHLA-I-CD8 levels in the blood serum and EBC were discovered in patients with severe COPD. The findings suggest a pathogenetic role of the investigated soluble molecules of the COPD development and allow considering the content of sCD8, sCD25, and sHLA-I-CD8 molecules as additional novel systemic and endobronchial markers of the progression of chronic inflammation of this disease

Publisher Copyright: © 2016 by the authors; licensee MDPI, Basel, Switzerland.Hepatitis delta virus (HDV) is a viroid-like blood-borne human pathogen that accompanies hepatitis B virus infection in 5% patients. HDV has been studied for four decades; however, the knowledge on its life-cycle and pathogenesis is still sparse. The studies are hampered by the absence of the commercially-available HDV-specific antibodies. Here, we describe a set of reproducible methods for the expression in E. coli of His-tagged small antigen of HDV (S-HDAg), its purification, and production of polyclonal anti-S-HDAg antibodies in rabbits. S-HDAg was cloned into a commercial vector guiding expression of the recombinant proteins with the C-terminal His-tag. We optimized S-HDAg protein purification procedure circumventing a low affinity of the His-tagged S-HDAg to the Ni-nitrilotriacetyl agarose (Ni-NTA-agarose) resin. Optimization allowed us to obtain S-HDAg with >90% purity. S-HDAg was used to immunize Shinchilla grey rabbits which received 80 µg of S-HDAg in two subcutaneous primes in the complete, followed by four 40 µg boosts in incomplete Freunds adjuvant. Rabbits were bled two weeks post each boost. Antibody titers determined by indirect ELISA exceeded 107. Anti-S-HDAg antibodies detected the antigen on Western blots in the amounts of up-to 100 pg. They were also successfully used to characterize the expression of S-HDAg in the eukaryotic cells by immunofluorescent staining/confocal microscopy.publishersversionPeer reviewe
