Dopamine Receptors and TAAR1 Functional Interaction Patterns in the Duodenum Are Impaired in Gastrointestinal Disorders.

Currently, there is a growing amount of evidence for the involvement of dopamine receptors and the functionally related trace amine-associated receptor, TAAR1, in upper intestinal function. In the present study, we analyzed their expression in the duodenum using publicly accessible transcriptomic data. We revealed the expression of , , , , and genes in different available datasets.

Spontaneous Vibrations and Stochastic Resonance of Short Oligomeric Springs.

There is growing interest in molecular structures that exhibit dynamics similar to bistable mechanical systems. These structures have the potential to be used as two-state operating units for various functional purposes. Particularly intriguing are the bistable systems that display spontaneous vibrations and stochastic resonance.

Spontaneous Synchronization of Two Bistable Pyridine-Furan Nanosprings Connected by an Oligomeric Bridge.

The intensive development of nanodevices acting as two-state systems has motivated the search for nanoscale molecular structures whose long-term conformational dynamics are similar to the dynamics of bistable mechanical systems such as Euler arches and Duffing oscillators. Collective synchrony in bistable dynamics of molecular-sized systems has attracted immense attention as a potential pathway to amplify the output signals of molecular nanodevices. Recently, pyridine-furan oligomers of helical shape that are a few nanometers in size and exhibit bistable dynamics similar to a Duffing oscillator have been identified through molecular dynamics simulations.

[Assessment of the phenotypic composition of lymphocytes, immunoglobulins and their relationships in patients with chronic rinosinusitis].

Objective: The study of the population and subpopulation content of lymphocytes and immunoglobulins and their associations in IgE-mediated CRS relative to other CRS and the control group.

Material And Methods: 23 patients with IgE-mediated chronic rhinusinusitis and 67 patients with normal IgE blood levels were examined. For analysis, flow cytometry (Cytomics FC500, Beckman Coulter, USA), using monoclonal antibodies CD3, CD4, CD8, CD16, CD19 and enzyme immunoassay (Thermo Scientific Multiskan FC, Thermo Fisher Scientific, USA), using IgA, IgM, IgE and IgG in serum, statistical processing was performed using Statistica 7.

Neurophotonic methods in approach to in vivo animal epileptic models: Advantages and limitations.

Neurophotonic technology is a rapidly growing group of techniques that are based on the interactions of light with natural or genetically modified cells of the neural system. New optical technologies make it possible to considerably extend the tools of neurophysiological research, from the visualization of functional activity changes to control of brain tissue excitability. This opens new perspectives for studying the mechanisms underlying the development of human neurological diseases.
