[Problems of poliomyelitis eradication].

The article is devoted to the problems of implementation of the WHO Global Polio Eradication Initiative. The influence of the features of poliovirus infection and poliovirus vaccines on the course of the program, its successes and difficulties is considered, the issue of possibility of eradication this infection is discussed.

[Infant botulism: an underestimated problem. A review].

The article is devoted to a form of botulism that has been little studied in our country and is registered exclusively in infants. The fundamental difference between this form and the most common foodborne botulism is that infants become infected by ingestion of spores, followed by their germination, colonization of the intestines and production of botulinum toxin , which leads to the development of life-threatening flaccid paralysis. Taking into account the peculiarities of pathogenesis, the clinical manifestations of infant botulism have some features, which are discussed by the authors.

[Coagulase-negative staphylococci as a significant fact of generalization of infection in persons with a burdened comorbid background].

Since the era of the widespread introduction of antibiotics into the human sphere of activity, the problem of antimicrobial resistance has become an urgent and very important topic around the world. Recently, coagulasonegative staphylococci (CoNS), which are representatives of opportunistic microorganisms of the microbiome of the skin and mucous membranes of healthy people, have made a certain contribution to its progression. For a long time, they did not pose a threat to patients, but in recent decades among microorganisms they have been seeded in more than two-thirds of patients with postoperative mediastinitis, catheter-associated infections, as well as from wounds of the neck vessels and the inguinal region separated by pacemaker beds.

Selectivity Control in Nitroaldol (Henry) Reaction by Changing the Basic Anion in a Chiral Copper(II) Complex Based on ()-2-Aminomethylpyrrolidine and 3,5-Di--butylsalicylaldehyde.

This article is a continuation of our previous research on the catalytic capability of a chiral copper complex based on commercially available ()-2-aminomethylpyrrolidine and 3,5-di--butylsalicylaldehyde with various counter-anions in the asymmetric Henry reaction. Our findings indicate that depending on the type of base used, chiral nitroalcohols with yields up to 98% and values up to 77%, as well as β-nitrostyrenes with yields up to 88%, can be produced. Additionally, it has been found that the outcome of the reaction and the catalytic properties of copper (II) complexes ()- and ()- are influenced by the structure of the aldehyde used.

Search for the Exclusive W Boson Hadronic Decays W^{±}→π^{±}γ, W^{±}→K^{±}γ and W^{±}→ρ^{±}γ with the ATLAS Detector.

A search for the exclusive hadronic decays W^{±}→π^{±}γ, W^{±}→K^{±}γ, and W^{±}→ρ^{±}γ is performed using up to 140  fb^{-1} of proton-proton collisions recorded with the ATLAS detector at a center-of-mass energy of sqrt[s]=13  TeV. If observed, these rare processes would provide a unique test bench for the quantum chromodynamics factorization formalism used to calculate cross sections at colliders. Additionally, at future colliders, these decays could offer a new way to measure the W boson mass through fully reconstructed decay products.
