MXene as a novel cartridge for N-glycan enrichment

Autor: Juvissan Aguedo, Zuzana Pakanova, Lenka Lorencova, Marek Nemcovic, Peter Kasak, Marek Barath, Pavol Farkas, Jan Tkac

Publikováno v: Analytica Chimica Acta

In this study, we applied MXene as column cartridge for N-glycan enrichment from human samples with a focus on the analysis of sialic acid linkages using a derivatisation protocol followed by glycan analysis via Matrix Assisted Laser Desorption Ionis

Redox features of hexaammineruthenium(III) on MXene modified interface: Three options for affinity biosensing

Autor: Veronika Pinkova Gajdosova, Lenka Lorencova, Peter Kasak, Monika Jerigova, Dusan Velic, Lubomir Orovcik, Marek Barath, Pavol Farkas, Jan Tkac

Publikováno v: Analytica Chimica Acta. 1227:340310

In this article we describe construction of a bioreceptive interface for detection of a breast cancer biomarker carbohydrate antigen CA15-3. The conductive interface was patterned by a 2D nanomaterial MXene, to which a mixed layer containing sulfobet

How do the carbon and nitrogen sources affect the synthesis of β-(1,3/1,6)-glucan, its structure and the susceptibility of Candida utilis yeast cells to immunolabelling with β-(1,3)-glucan monoclonal antibodies?

Autor: Anna Bzducha-Wróbel, Pavol Farkaš, Sandra Bieliková, Alžbeta Čížová, Marzena Sujkowska-Rybkowska

Publikováno v: Microbial Cell Factories, Vol 23, Iss 1, Pp 1-16 (2024)

Abstract Background The need to limit antibiotic therapy due to the spreading resistance of pathogenic microorganisms to these medicinal substances stimulates research on new therapeutic agents, including the treatment and prevention of animal diseas

Ground state and stability of the fractional plateau phase in metallic Shastry–Sutherland system TmB4

Autor: Matúš Orendáč, Slavomír Gabáni, Pavol Farkašovský, Emil Gažo, Jozef Kačmarčík, Miroslav Marcin, Gabriel Pristáš, Konrad Siemensmeyer, Natalya Shitsevalova, Karol Flachbart

Publikováno v: Scientific Reports, Vol 11, Iss 1, Pp 1-8 (2021)

Abstract We present a study of the ground state and stability of the fractional plateau phase (FPP) with M/Msat = 1/8 in the metallic Shastry–Sutherland system TmB4. Magnetization (M) measurements show that the FPP states are thermodynamically stab

Synthesis of Biotin-Tagged Chitosan Oligosaccharides and Assessment of Their Immunomodulatory Activity

Autor: Yury E. Tsvetkov, Ema Paulovičová, Lucia Paulovičová, Pavol Farkaš, Nikolay E. Nifantiev

Publikováno v: Frontiers in Chemistry, Vol 8 (2020)

Chitin, a polymer of β-(1→4)-linked N-acetyl-d-glucosamine, is one of the main polysaccharide components of the fungal cell wall. Its N-deacetylated form, chitosan, is enzymatically produced in the cell wall by chitin deacetylases. It exerts immun

Importance of Candida Antigenic Factors: Structure-Driven Immunomodulation Properties of Synthetically Prepared Mannooligosaccharides in RAW264.7 Macrophages

Autor: Ema Paulovičová, Lucia Paulovičová, Pavol Farkaš, Alexander A. Karelin, Yury E. Tsvetkov, Vadim B. Krylov, Nikolay E. Nifantiev

Publikováno v: Frontiers in Cellular and Infection Microbiology, Vol 9 (2019)

The incidence and prevalence of serious fungal infections is rising, especially in immunosuppressed individuals. Moreover, co-administration of antibiotics and immunosuppressants has driven the emergence of new multidrug-resistant pathogens. The sign
