A Blue-Purple Pigment-Producing Bacterium Isolated from the Vezelka River in the City of Belgorod.

Violacein is a biotechnologically significant secondary metabolite due to its antibacterial, antifungal, and other properties. Isolation, research, and identification of violacein producing strains are of interest for the development of biotechnological processes, in order to enhance the biosynthesis of this compound. The purpose of the present work was to study the properties of a newly isolated bacterium capable of synthesizing blue-purple pigment.

[The First Russian Consensus on the Multilevel Abobotulinumtoxin A Injections in Spastic Forms of Cerebral Palsy].

Spasticity treatment is one of the key aspects of the contemporary cerebral palsy (CP) rehabilitation that influences on the effectiveness of other methods. The paper presents the first Russian document that unites the recommendations for the BTA treatment of CP and could be used as the guideline for the multilevel injections. The Russian consensus on the multilevel botulinum toxin A (BTA) treatment of spastic CP is based on the international data and the results of national studies.

[The results of single-event multilevel orthopedic surgeries and the early rehabilitation used in complex with botulinum toxin treatment in patients with spastic forms of cerebral palsy].

Objective: To evaluate motor possibilities of patients with children spastic palsy (CSP) one year after single-event multilevel orthopedic low extremity surgeries in combination with early rehabilitation treatment including botulinum toxin treatment.

Material And Methods: Authors studied the results of operative orthopedic treatment in 55 patients with CSP, aged from 5 to 17 years (mean 11.9 ± 2.

dlk acts as a negative regulator of Notch1 activation through interactions with specific EGF-like repeats.

The protein dlk, encoded by the Dlk1 gene, belongs to the Notch epidermal growth factor (EGF)-like family of receptors and ligands, which participate in cell fate decisions during development. The molecular mechanisms by which dlk regulates cell differentiation remain unknown. By using the yeast two-hybrid system, we found that dlk interacts with Notch1 in a specific manner.

A dominant negative mutant beta 2-microglobulin blocks the extracellular folding of a major histocompatibility complex class I heavy chain.

The major histocompatibility complex class I (MHC1) molecule plays a crucial role in cytotoxic lymphocyte function. beta 2-Microglobulin (beta 2m) has been demonstrated to be both a structural component of the MHC1 complex and a chaperone-like molecule for MHC1 folding. beta 2m binding to an isolated alpha 3 domain of MHC1 heavy chain at micromolar concentrations has been shown to accurately model the biochemistry and thermodynamics of beta 2m-driven MHC1 folding.
