Large-scale genomic analysis of Elizabethkingia anophelis.

The recent emergence of Elizabethkingia anophelis as a human pathogen is a major concern for global public health. This organism has the potential to cause severe infections and has inherent antimicrobial resistance. The potential for widespread outbreaks and rapid global spread highlights the critical importance of understanding the biology and transmission dynamics of this infectious agent.

Genomic analysis of multidrug-resistant isolated from raw bovine milk.

is a gram-negative, aerobic bacterium mostly known as an organic pollutant degrading and growth-promoting microorganism. However, it recently emerged as an opportunistic human pathogen. To date, the source of infection is not clear.

Online activity of mosques and Muslims in the Netherlands: A study of Facebook, Instagram, YouTube and Twitter.

Research on Muslim minorities in western societies has mainly focused on offline behavior, such as mosque attendance, whereas little is known about their presence in the online world. This study explores the online visibility and activities of all (478) mosques in the Netherlands. We collected data on personal websites and four social media platforms (Facebook, Twitter, Instagram and YouTube).

[Transcranial direct current stimulation in neurology and psychiatry].

Transcranial direct current stimulation (tDCS) is a non-invasive method of modulating brain excitability by low intensity direct current. At present, there are numerous studies of tDCS application in various mental and neurological diseases. In this review, the data of tDCS efficiency in the treatment of different disorders are presented and the recommendations on using this method in clinical practice are given.

Transcranial direct current stimulation of 20- and 30-minutes combined with sertraline for the treatment of depression.

Background: Transcranial direct current stimulation (tDCS) can be an effective treatment for depression, however, the duration of the stimulation session, among other parameters, needs to be optimized.

Methods: 69 mild to moderately depressed patients (age 37.6±10.

[The effect of childhood stress on the development of mental disorders in adults].

There is evidence that not only severe stressful events, but also common low-threat events, in particular chronic ones, may cause or provoke some mental disorders. The literature data on the degree of pathogenicity of stress factors are insufficient. Authors attempted to summarize the established facts in the following aspects: current conceptions on the physiology and pathology of stress in the frames of the problem of psychosomatic disorders, deprivation in childhood, neurobiological consequences of childhood stress, psychiatric consequences of stress in childhood.

Relaxation of microparticles exposed to hydrodynamic forces in microfluidic conduits.

The behavior of microparticles exposed to gravitational and lift forces and to the velocity gradient in flow velocity profile formed in microfluidic conduits is studied from the viewpoint of the transient period (the relaxation) between the moment at which a particle starts to be transported by the hydrodynamic flow and the time at which it reaches an equilibrium position, characterized by a balance of all active forces. The theoretical model allowing the calculation of the relaxation time is proposed. The numerical calculus based on the proposed model is compared with the experimental data obtained under different experimental conditions, namely, for different lengths of microfluidic channels, different average linear velocities of the carrier liquid, and different sizes and densities of the particles used in the study.

Novel highly charged silica-coated Tb(III) nanoparticles with fluorescent properties sensitive to ion exchange and energy transfer processes in aqueous dispersions.

Novel silica-coated Tb(III) nanoparticles with high luminecsence were synthesized using the reverse microemulsion procedure. The quenching of luminescent properties of these nanoparticles can be achieved by ion exchange and energy transfer mechanisms. The quenching through the ion exchange of Tb(III) by H+ or La(III) is time dependent, indicating that the ion exchange is probably diffusion controlled.

Study of dynamic adsorption behavior of large-size protein-bearing particles.

The subject of this paper is an investigation of the peculiarities of dynamic adsorption behavior of nanoparticles. For this purpose, virus-mimicking synthetic particles bearing different proteins at their outer surface were specially constructed using two approaches, e.g.

Detection of antibodies to opioid and glutamate receptors by latex agglutination and enzyme immunoassay.

We studied adsorption capacity of 5 latexes to synthetic peptide fragments of mu- and delta-opioid receptors and to GluR1 and NR2A subunits of glutamate receptor. Levels of autoantibodies to opioid receptors in the latex agglutination test and enzyme immunoassay were in good correlation. The level of autoantibodies to opioid receptors measured by these methods was increased in patients with opium narcomania, while the content of autoantibodies to the glutamate receptor subunits was increased in epileptics.

Effect of channel width on the retention of colloidal particles in polarization, steric, and focusing micro-thermal field-flow fractionation.

The effect of the channel width on the performance of separation by micro-thermal field-flow fractionation (micro-TFFF) of the carboxylated polystyrene latex particles was studied by using the particles in diameter range from 100 nm to 3800 nm. It has been shown that the retention order follows the anticipated polarization, steric, and focusing mechanism in the corresponding size range and under the specific conditions, appropriate to each channel thickness. However, the attractive interactions of the particles with the accumulation wall can complicate the separation as has been proven by the experiments carried out by using the carrier liquids of different ionic strengths.

Micro-thermal focusing field-flow fractionation.

Focusing mechanism was effectively exploited to separate large (micrometer-size) particles by using new micro-thermal field-flow fractionation (micro-TFFF). It has been shown that the retention order of micrometer-size particles at high field strength can be explained by the mechanism of steric exclusion only at lowest flow rates of the carrier liquid. A simplistic, purely mechanical model of steric exclusion is not accurate to describe the retention at higher flow rates where the focusing phenomenon appears.

[Determination of antibodies to opiate receptors by latex agglutination and immunoenzyme analysis].

Adsorption ability of few kinds of latex covered by synthetic peptide fragments of mu- and delta-opiate receptors (OR) is investigated. The levels of autoantibodies to opiate receptors fragments in the blood serum of patients with drug abuse are detected by latex agglutination and ELISA. The patients with drug abuse demonstrated positive latex agglutination reaction for level specific antibodies from 10.
