Development of photoactive ZnS-SiO composites on biogenic silica matrix for organic pollutant degradation.

Sulfide ZnS-SiO composite photocatalysts with biogenic silica matrix were prepared by sol-gel method based on wet gel and xerogel. FT-IR, SEM, XRD, EDXRF, UV-Vis, and XPS methods were systematically used to characterize the obtained materials. The use of support allowed to obtain stable porous (S = 79-105 m g; V = 0.

[Experience with the use of bacteriophages in patients with neurogenic lower urinary tract dysfunction, complicated by recurrent lower urinary tract infection].

Clinical cases of three patients with neurogenic lower urinary tract dysfunction, complicated by chronic urinary tract infection are presented in the article. All patients underwent clean intermittent catheterization and, in order to prevent symptomatic lower urinary tract infections, received bacteriophage therapy with a clinically proven positive effect. During 3 months follow-up, there were no episodes of urinary tract infection.

[Language, cultural adaptation and validation of the OABSS (Overactive Bladder Symptom Score) questionnaire in patients with overactive bladder].

Aim: To perform language and cultural adaptation and validation of the OABSS (Overactive Bladder Symptom Score) questionnaire among patients with overactive bladder (OAB), proposed as an effective tool for assessing the severity of symptoms and the efficiency of treatment in clinics of the Russian Federation.

Materials And Methods: In accordance with the protocols for carrying out such studies, the procedure of standardized forward-backward translation of the OABSS questionnaire was performed. Further, the intermediate Russian-language version was applied to 15 patients with subsequent correction of deficiencies and approval of the final Russian-language version of the questionnaire.

[Biofilm control in urological practice].

Urinary tract infections (UTIs) have long been among the most common diseases. In the structure of the general infectious morbidity, UTIs rank second after acute respiratory viral infection. Every year, researchers note an increasing number of mutations in the genomes of bacteria that cause infectious diseases, which leads to the formation of more and more aggressive forms of pathogens.

[Lower urinary tract symptoms and COVID-19].

The data presented in the review showed that the coronavirus affects not only the lungs, but also the organs of the urinary system. The new virus causes a mosaic, multi-organ disease with severe consequences after the egg and has a wide organotropism. The role of SARS-CoV-2 in the development of lower urinary tract symptoms (LUTs), which are manifested by frequent, imperative urges, dysuria, nocturia, is not entirely clear.

Oxidative destruction of phenol on Fe/SiO catalysts.

In the present study, the sol-gel technique helped to obtain Fe-containing samples with a base of amorphous silicon dioxide from rice husks RH-Fe and RH-Fe-300. These materials are characterized by IR spectroscopy, X-ray phase and X-ray spectral analysis. It was shown that the samples contain silicate structures Si-O-Si(Fe) and are in an amorphous state.

Heterogeneous photo-Fenton oxidation of lignin of rice husk alkaline hydrolysates using Fe-impregnated silica catalysts.

Present work shows results of a study on heterogeneous Fenton-like degradation of lignin alkaline hydrolysates formed in the process of obtaining a fibrous mass from rice husk. Fe-impregnate biogenic amorphous silica Fe/RH-SiO obtained from rice husk was used as a catalyst. Using IR spectroscopy, X-ray diffraction and EDX analysis it was shown that iron(III) oxide in the form of hematite is present on the catalyst surface.
