Recent advancements in brain computer interfaces (BCI) have demonstrated control of robotic systems by mental processes alone. Together with invasive BCI, electroencephalographic (EEG) BCI represent an important direction in the development of BCI systems. In the context of EEG BCI, the processing of EEG data is the key challenge. Unfortunately, advances in that direction have been complicated by a lack of large and uniform datasets that could be used to design and evaluate different data processing approaches...

Compact naphthalenediimide (NDI)-2,2,6,6-tetramethyl piperidine N-oxyl (TEMPO) dyad was prepared, with the aim to study the radical-enhanced intersystem crossing (EISC) and the formation of high spin states, as well as the electron spin polarization (ESP) dynamics. Compared to the previously reported radical-chromophore dyads, the present system shows a very high triplet state quantum yield (74%), long-lived triplet state (8.7 microseconds), fast EISC (338 ps) and absorption in the red spectral region. Time-resolved electron paramagnetic resonance (TRERP) spectroscopy shows that, on photoexcitation in fluid solution at room temperature, the D0 state of TEMPO moiety produces strong emissive (E) polarization, owing to the quenching of the excited singlet state of NDI by the radical moiety (electron exchange J > 0)...

Oxygen is used by eukaryotic cells for metabolic transformations and energy production in mitochondria. Under physiological conditions, there is a constant endogenous production of free radicals that interact as signaling molecules in physiological mechanisms. Free radicals are neutral molecules, which are produced by separation of ions and molecules. In regular conditions production and disposal of free radicals are at equilibrium. However this equilibrium may not always be experienced, where these species are not eliminated by antioxidants or are excessively produced...

AIM: Magnetic resonance imaging (MRI) is generally the preferred method for assessing lesions of the knee cartilage and subchondral bone. There have been a few cartilage imaging studies using real-time elastosonography (RTE), which has increased in importance and range of use in recent years. The aim of this cadaveric study was to assess the efficacy of a new diagnostic method combining USG and RTE and also to perform intra-articular examinations together with arthroscopy. METHODS: A total of 12 fresh unpaired human knees were examined...

PURPOSE: The aim of our study was to investigate the impact of the ABO blood groups and blood-based biomarkers on the growth kinetics of renal angiomyolipoma (AML). METHODS: A total of 124 patients with AML who were followed-up between 2010 and 2018 were retrospectively reviewed. The patients' characteristics were recorded, including age, body mass index (BMI), blood pressure, smoking history, and ABO blood group. Baseline laboratory test results, including serum creatinine, AST, ALT, platelet, neutrophil and lymphocyte count, were used to calculate the estimated glomerular filtration rate (eGFR), neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), and De Ritis ratio...

Introduction: Tumor associated macrophages (TAMs) promote tumor development, angiogenesis and distal metastasis. In previous studies, we showed that Cat Eye Syndrome Critical Region Protein 1 (CECR1) is expressed by M2-like TAMs in human glioma samples. CECR1 promoted M2 TAMs differentiation and affected glioma cell proliferation and migration. Here we investigated the proteomic profile of TAMs expressing CECR1 in absence or presence of glioma cells. Results: CECR1 siRNA transfection upregulated 67 proteins in THP-1-derived Macrophages (MQs)...

BACKGROUND: Early infantile epileptic encephalopathies are severe disorders consisting of early-onset refractory seizures accompanied often by significant developmental delay. The increasing availability of next-generation sequencing has facilitated the recognition of single gene mutations as an underlying aetiology of some forms of early infantile epileptic encephalopathies. OBJECTIVES: This study was designed to identify candidate genes as a potential cause of early infantile epileptic encephalopathy, and then to provide genetic and functional evidence supporting patient variants as causative...

In this study, we constructed a new and sensitive ITO based electrochemical immunosensor for detection of interleukin 1β (IL-1β), a cancer biomarker found in serum and saliva. 6-phosphonohexanoic acid (PHA) was used as a biomolecule immobilization matrix for the first time. Anti-IL-1β antibody was utilized as a biorecognition molecule that immobilized onto carboxyl groups of 6-phosphohexanoic acid (PHA) via amide bond. Selective interaction between anti- IL-1β antibodies and IL-1β antigens was investigated by Electrochemical Impedance Spectroscopy (EIS), Cyclic Voltammetry (CV) and Single Frequency Impedance (SFI) methods...

OBJECTIVE: Several indications for sutureless aortic valve replacement (SU-AVR) have been a matter of debate. We evaluated our experience with Perceval-S® (LivaNova group, Saluggia, Italy) SU-AVR in patients with severe aortic stenosis (AS) involving bicuspid aortic valve (BAV), even though presence of BAV is still considered to be a contraindication for sutureless valves. METHODS: From January 2013 through March 2018, thirteen patients with severe aortic stenosis involving BAV underwent SU-AVR with the Perceval-S® (LivaNova group, Saluggia, Italy) prosthesis in a single center...

We report, to the best of our knowledge, the first employment of a self-injection locking scheme for the demonstration of a tunable InGaN/GaN semiconductor laser diode. We have achieved a 7.11 nm (521.10-528.21 nm) tunability in a green color with different injection currents and temperatures. The system exhibited mode spectral linewidth as narrow as ∼69  pm and a side mode suppression ratio as high as ∼28  dB, with a maximum optical power of ∼16.7  mW. In the entire tuning window, extending beyond 520 nm, a spectral linewidth of ≤100  pm, high power, and stable performance were consistently achieved, making this, to the best of our knowledge, the first-of-its-kind compact tunable laser system attractive for spectroscopy, imaging, sensing systems, and visible light communication...

In vivo photoacoustic (PA) flow cytometry (PAFC) has great clinical potential for early, noninvasive diagnosis of cancer, infections (e.g., malaria and bacteremia), sickle anemia, and cardiovascular disorders, including stroke prevention through detection of circulating white clots with negative PA contrast. For clinical applications, this diagnostic platform still requires optimization and calibration. We have already demonstrated that this need can be partially addressed by in vivo examination of large mouse blood vessels, which are similar to human vessels used...

In the title Schiff base compound, C23 H23 NO, the two ring systems are twisted by 51.40 (11)° relative to each other. In the crystal, the mol-ecules are connected by weak C-H⋯π inter-actions, generating a three-dimensional supra-molecular structure. Hirshfeld surface analysis and two-dimensional fingerprint plots indicate that the most important contributions to the crystal packing are from H⋯H (67.2%), C⋯H/H⋯C (26.7%) and C⋯C (2.5%) inter-actions.

BACKGROUND: The liver R2* value is widely used as a measure of liver iron but may be confounded by the presence of hepatic steatosis and other covariates. PURPOSE: To identify the most influential covariates for liver R2* values in patients with nonalcoholic fatty liver disease (NAFLD). STUDY TYPE: Retrospective analysis of prospectively acquired data. POPULATION: Baseline data from 204 subjects enrolled in NAFLD/NASH (nonalcoholic steatohepatitis) treatment trials...
