BACKGROUND: Hard ticks are the main vectors of tick-borne encephalitis virus (TBEV). Free carnitine (FC) and acylcarnitines (AC) have the basic role in β-oxidation as well as the modulation of immune and nervous system. Homeostasis of carnitines in the TBE patients was not studied so far. OBJECTIVES: This study aimed to evaluate FC and AC serum concentrations in patients with meningitis due to TBEV infection before and after 14 ± 3 days of treatment. MATERIAL AND METHODS: The study was performed in 14 patients aged 48 ± 29 years that were divided a posteriori (based on their FC level before and after treatment) into 2 subgroups: 1-8 and 9-14...

A sensitive and straightforward method for discriminating between surface-adsorbed double-stranded DNA (dsDNA) and single-stranded DNA (ssDNA), based on analysis of the fluorescence emission spectra of DNAs dyed with the metachromatic dye acridine orange, has been developed. Since the degree of discrimination between dsDNA and ssDNA is dependent on dye-base ratio (as has been shown in early studies of DNAs in solution), a specific, reproducible protocol for obtaining good ss-ds discrimination was needed. We studied the emission spectra for DNAs dyed in-situ on two different surfaces, polymethylmethacrylate and poly-l-lysine, using acridine orange solutions of varying concentrations in either 2-(N-morpholino)ethanesulfonic acid (MES) or Tris-Borate EDTA (TBE) buffers...

Tick-borne encephalitis (TBE), which is endemic across large regions of Europe and Asia, is most effectively prevented through vaccination. Three-dose primary TBE vaccination schedules are either rapid (0,7,21-days) or conventional (0,28-84-days, 9-12-months). The second dose can also be administered at 14 days for faster priming and sero-protection). Areas covered: We used a three-step selection process to identify 21 publications comparing the immunogenicity and/or safety of different schedules. Expert commentary: Priming with two or three TBE vaccine doses was highly immunogenic...

Threshold-based thermal time models provide insight to the physiological switch from the dormant to the non-dormant, germinating seed. This approach was used to quantify the different growth responses of the embryo of seeds purported to have morphophysiological dormancy (MPD) through the complex phases of dormancy release and germination. Aquilegia barbaricina seeds were incubated at constant temperatures (10 - 25°C) and 25/10°C, without pre-treatment, after warm+cold stratification (W+C), and GA3 treatment...

BACKGROUND AND PURPOSE: Tick-borne encephalitis (TBE) is an infection of the central nervous system (CNS) caused by tick-borne encephalitis virus (TBEV) and transmitted by ticks, with a variety of clinical manifestations. The incidence of TBE in Europe is increasing due to an extended season of the infection and the enlargement of endemic areas. Our objectives are to provide recommendations on the prevention, diagnosis and management of TBE, based on evidence or consensus decisions. METHODS: For systematic evaluation, the literature was searched from 1970 to 2015 (including early online publications of 2016), and recommendations were based on evidence or consensus decisions of the Task Force when evidence-based data were not available...

BACKGROUND: Tick-borne encephalitis (TBE) is an important tick-borne disease in Europe. Detection of the TBE virus (TBEV) in local populations of Ixodes ricinus ticks is the most reliable proof that a given area is at risk for TBE, but this approach is time-consuming and expensive. A cheaper and simpler approach is to use immunology-based methods to screen vertebrate hosts for TBEV-specific antibodies and subsequently test the tick populations at locations with seropositive animals. RESULTS: The purpose of the present study was to use goats as sentinel animals to identify new risk areas for TBE in the canton of Valais in Switzerland...

Tick-borne encephalitis (TBE) is the most common tick-borne viral infection in Eurasia; thousands of human cases are annually reported from several European countries. Several tick species are vectors of the tick-borne encephalitis virus (TBEV), while TBE appears to be spreading from the Eurasian continent westward to Europe. Fifteen study sites were chosen from five territories of southern Ukraine, including Odessa, Mykolaiv, Kherson Oblast, the Autonomous Republic of Crimea, and Sevastopol. Tick collection was performed in spring season of three consecutive years (1988-1990) using either flagging technique or direct collection of specimens feeding on cattle...

BACKGROUND: Host factors determining the clinical presentation of tick-borne encephalitis (TBE) are not fully elucidated. The peripheral inflammatory response to TBE virus is hypothesized to facilitate its entry into central nervous system by disrupting the blood-brain barrier with the involvement of a signaling route including Toll-like receptor 3 (TLR3) and pro-inflammatory cytokines macrophage migration inhibitory factor (MIF), tumor necrosis factor-α (TNFα), and interleukin-1 beta (IL-1β)...

Rapid improvement of tick-borne encephalitis after treatment with corticosteroids Tick-borne encephalitis (TBE) is a viral disease transmitted by ticks. The virus is divided into three subtypes named Western, Siberian and Far Eastern TBE virus (TBEV). Western TBEV is endemic in parts of Europe and Sweden and typically causes a biphasic illness with influenza-like symptoms followed by neurological symptoms ranging from mild meningitis to severe meningoencephalitis and death. Despite an effective vaccine, TBE is increasing in Sweden and Europe...

Tick-borne encephalitis (TBE) is one of natural foci diseases transmitted by ticks. Its distribution and transmission are closely related to geographic and environmental factors. Identification of environmental determinates of TBE is of great importance to understanding the general distribution of existing and potential TBE natural foci. Hulunbuir, one of the most severe endemic areas of the disease, is selected as the study area. Statistical analysis, global and local spatial autocorrelation analysis, and regression methods were applied to detect the spatiotemporal characteristics, compare the impact degree of associated factors, and model the risk distribution using the heterogeneity...

Tick-borne encephalitis (TBE) is a viral disease that can have a severe acute clinical course and considerable long-term morbidity. As there is no causal treatment currently available for TBE, vaccination is the only way to combat the disease in endemic areas. The studies presented here were conducted to obtain prospective long-term TBE serum antibody persistence data of subjects up to 10years after the first booster with FSME-IMMUN. This report presents the results of 2 follow-up studies in the same study population of 315 healthy adults...

Human faces in surveillance videos often suffer from severe image blur, dramatic pose variations, and occlusion. In this paper, we propose a comprehensive framework based on Convolutional Neural Networks (CNN) to overcome challenges in video-based face recognition (VFR). First, to learn blur-robust face representations, we artificially blur training data composed of clear still images to account for a shortfall in real-world video training data. Using training data composed of both still images and artificially blurred data, CNN is encouraged to learn blur-insensitive features automatically...

Tick-borne encephalitis (TBE) has become an increasing public health threat in recent years, ranging from Europe, through far-eastern Russia to Japan and northern China. However, the neglect of its expansion and scarce analyses of the dynamics have made the overall disease burden and the risk distribution of the disease being unclear in mainland China. In this study, we described epidemiological characteristics of 2117 reported human TBE cases from 2006 to 2013 in mainland China. About 99% of the cases were reported in forest areas of northeastern China, and 93% of reported infections occurred during May-July...
