: Botanical Characteristics, Proximate, Mineral Composition, and Cytotoxic Activity.

(Chenopodiaceae) is an under-investigated annual plant that occurs in dry areas stretching from eastern and south-eastern Europe to East Asia. This article presents the botanical characterization and examination of proximate parameters, minerals and cytotoxic activity of that grows wild in Kazakhstan. The results of morphological analysis using a light microscope, based on cross-sections of stems, roots and leaves, provide the necessary data to develop a regulatory document for this herbal substance as a raw material for use in the pharmaceutical, cosmetic and food industries.

Gas Chromatography-Mass Spectrometry Profiling of Volatile Metabolites Produced by Some spp. and Evaluation of Their Antibacterial and Antibiotic Activities.

species produce different classes of antimicrobial and antioxidant substances: peptides or proteins with different structural compositions and molecular masses and a broad range of volatile organic compounds (VOCs), some of which may serve as biomarkers for microorganism identification. The aim of this study is the identification of biologically active compounds synthesized by five species using gas chromatography coupled to mass spectrometry (GC-MS). The current study profoundly enhances the knowledge of antibacterial and antioxidant metabolites ensuring the unambiguous identification of VOCs produced by some species, which were isolated from vegetable samples of potato, carrot, and tomato.

Molecular Characterization of Some Species from Vegetables and Evaluation of Their Antimicrobial and Antibiotic Potency.

Numerous natural habitats, such as soil, air, fermented foods, and human stomachs, are home to different strains. Some strains have a distinctive predominance and are widely recognized among other microbial communities, as a result of their varied habitation and physiologically active metabolites. The present study collected vegetable products (potato, carrot, and tomato) from local markets in Almaty, Kazakhstan.

[Serological method of detecting the antigens of the causative agent of Sonne dysentery in lysates of the fecal inoculates from patients].

Serological method of detection of Sh. sonnei antigens in the lysates of the patients, fecal cultures is suggested and approved. In the majority of cases of the results of bacteriological and serological methods of study of the feces coincided.
