Neuroimaging studies demonstrate gray matter (GM) macrostructural abnormalities in patients with schizophrenia (SCZ). While ex-vivo and genetic studies suggest cellular pathology associated with abnormal neurodevelopmental processes in SCZ, few in-vivo measures have been proposed to target microstructural GM organization. Here, we use diffusion heterogeneity- to study GM microstructure in SCZ. Structural and diffusion magnetic resonance imaging (MRI) were acquired on a 3 Tesla scanner in 46 patients with SCZ and 37 matched healthy controls (HC)...

Congenital bladder exstrophy is a severe congenital malformation identified in one out of 30,000-50,000 live newborns and seen more often in girls. Some patients develop osteoarthritis of the hip joints which requires total hip arthroplasty. Reports of such cases are very rare in the world literature, which prompted us to present two cases treated at our Department and analyse their early outcomes. Our experience so far has been rather modest but the results encourage considering total hip arthroplasty in the treatment of hip osteoarthritis in future patients with pubic symphysis separation in the course of congenital bladder exstrophy...

BACKGROUND: The study aimed to compare sex differences in the morphology and spatial orientation of pelvic acetabula to advance the understanding of hip anatomy. MATERIAL AND METHODS: The study was based on three-dimensional reconstructions of computed tomography images of 50 female and 50 male acetabula. The images were used for spatial analysis of hip acetabula relative to the base of the sacral bone as the plane of reference. Statistical analysis was performed to compare angles relevant to the actual axis of the acetabulum (inclination angle, anteversion angle, tilt angle) as well as the volume and inner surface area of the acetabulum...

We aim to investigate whether phase shift between respiratory oscillations in cerebral blood flow velocity (CBFV) and arterial blood pressure (ABP) is associated with changes in cerebral autoregulation (CA) or reflects the mechano-elastic properties of the cerebrovascular bed. The relationships between respiratory phase shift and slow wave phase shift versus cerebrovascular time constant (the product of cerebrovascular resistance and compliance) and the index of CA (Mx) were analyzed during breathing at 6, 10, and 15 breaths min(-1) in 39 volunteers...

Anion-π interactions have been shown to stabilize flavoproteins and to regulate the redox potential of the flavin cofactor. They are commonly attributed to electrostatic forces. Here we show that anion-flavin interactions have a substantial charge-transfer component. Our conclusion emanates from a multiapproach theoretical analysis and is backed by previously reported observations of absorption bands, originating from charge transfer between oxidized flavin and proximate cystein thiolate groups. This partial covalency of anion-flavin contacts renders classical simulations of flavoproteins questionable...

Irradiation of nanoscale clusters and large molecules with intense laser pulses transforms them into highly-excited non- equilibrium states. The dynamics of intense laser-cluster interaction is encoded in electron kinetic energy spectra, which contain signatures of direct photoelectron emission as well as emission of thermalized nanoplasma electrons. In this work we report on a so far not observed spectrally narrow bound state signature in the electron kinetic energy spectra from mixed Xe core - Ar shell clusters ionized by intense extreme-ultraviolet (XUV) pulses from a free-electron-laser...

Somatic mutations in NRAS, PTEN and AKT1 genes are rarely (~1%) reported in primary NSCLC, but their role in carcinogenesis have been proven. Therefore, we assessed the frequency of them in 145 FFPE tissue samples from CNS metastases of NSCLC using the real-time PCR technique. We identified four (two NRAS and single AKT1 and PTEN) mutations in CNS metastases of NSCLC. All mutations were observed in current male smokers (4% out of the male group; 4/100 and 4.25% out of smokers; 4/94). Three mutations have been detected in patients with SqCC (10...

We report on a 69-year-old woman who demonstrated native coronary artery and grafted vessel spasm following on-pump coronary artery bypass grafting (CABG). Despite intraaortic balloon pump (IABP) insertion, electrocardiogram (ECG) abnormalities did not disappear. Emergency coronary angiography (CAG) was performed. The patient was successfully treated with systemic and intracoronary injection of vasodilator agents. ECG changes disappeared, with normalized and stable hemodynamic function. Intraaortic balloon pump was maintained for 48 h...

BACKGROUND: Polycyclic aromatic hydrocarbons (PAHs) are the products of incomplete combustion or pyrolysis of various organic materials. Their ubiquity in the environment leads to measurable levels of exposure. However, the exposure varies strongly between different regions in Europe. Some PAHs with four or more rings are suspected to be human carcinogens. Therefore, the occupational and/or environmental exposure to PAHs may cause a significant health risk. The aim of investigation is to evaluate current levels of PAH exposure in defined groups of workers...

Multiway array decomposition methods have been shown to be promising statistical tools for identifying neural activity in the EEG spectrum. They blindly decompose the EEG spectrum into spatial-temporal-spectral patterns by taking into account inherent relationships among signals acquired at different frequencies and sensors. Our study evaluates the stability of spatial-temporal-spectral patterns derived by one particular method, parallel factor analysis (PARAFAC). We focused on patterns' stability over time and in population and divided the complete data set containing data from 50 healthy subjects into several subsets...

Although an isolation of elusive tricyanomethane HC(CN)3 (1) was recently reported, the existence of other HC4N3 species has yet to be confirmed. In this work, the relative stabilities, spectroscopic features and rearrangements of (1) and its isomers (2-5) are examined using single- (CCSD(T), CCSD(T)-F12) and multi-reference (MCSCF, MRPT2) methods. Tricyanomethane (1) is found to be the most stable of the HC4N3 isomers considered, followed by dicyanoketenimine (NC)2CCNH (2), the isomer comprising the C-C-N ring moiety with C-H bond (3), dicyanoisonitrile (NC)2CNCH (4), and the isomer comprising the ring moiety with N-H bond (5)...
