Silica‐gel incorporated carbon paste sensor for the electrocatalytic oxidation of famotidine and its application in biological sample analysis

open access: yesElectrochemical Science Advances, Volume 2, Issue 6, December 2022., 2022
Graphical Abstract. Abstract Famotidine (FAM) is an efficacious competitive drug, and a reversible inhibitor of H2‐histaminergic receptor action used to manage acid production in the stomach. Among the elderly population, this drug poses the risk of kidney failure and impaired mental health conditions. Additionally, FAM is an environmental contaminant.

Induction and manipulation of biomolecular condensates through spatially heterogeneous solution conditions

open access: yesChemBioChem, Accepted Article.
The study of biomolecular condensates (BMCs) is of great current interest because of the proposed roles of these types of assemblies in biological function and disease. In living cells, BMCs form in a highly heterogeneous environment and are influenced by concentration gradients of various relevant species.

Electrochemically mediated multi‐modal detection strategy‐driven sensor platform to detect and quantify pesticides

open access: yesElectrochemical Science Advances, Volume 2, Issue 6, December 2022., 2022
Abstract With the emergence of modern agronomy practices and the use of multiple synthetic pesticide agents to keep control over crop and field throughput, there lies a broad requirement for smart, accessible technologies to track pesticide contaminants in food, water, and other environmental matrices.

Cold‐Adapted Lipid A from Polaribacter sp. SM1127: A Study of Structural Heterogeneity and Immunostimulatory properties

open access: yesChemBioChem, Accepted Article.
Polaribacter sp. SM1127, a cold‐adapted marine Gram‐negative bacterium isolated from Laminaria in Arctic waters, plays a crucial role in nutrient cycling and biopolymer degradation in cold environments. Additionally, its exopolysaccharide (EPS) exhibits promising biotechnological potential, including antioxidant and wound‐healing properties. This study

A Fluorescent Aptasensor for Sensitive and Selective Determination of Epigenetic Cancer Biomarker N1‐Methyladenosine in Urine Samples

open access: yesChemistry – A European Journal, EarlyView.
Using N1‐methyladenosine, a cancer biomarker as a target, a highly selective DNA aptamer was obtained with excellent selectivity and affinity, allowing the detection with a limit of detection of 1.9 µm. Abstract N1‐methyladenosine (m1A) level in urine increases in the presence of cancer and is associated with the tumor size and stage.

Determination of phytic acid by capillary isotachophoresis combined with capillary zone electrophoresis (abstract only)

open access: yesCzech Journal of Food Sciences, 2004
The aim of this work was to find convenient method for detection of plant material in meat products. The adulteration of meat products is still actual problem, because meat products are cheaper with plant material. The Decree No.

Frosted DNA: β‐Galactosidase Control of Oligonucleotide Activity

open access: yesChemistry – A European Journal, EarlyView.
β‐Galactosidase is expressed at low level in many native cells and strongly upregulated in senescent cells. In the present study, we use β‐galactosidase activity as internal trigger to control the hybridization of oligonucleotides–eventually selective in senescent cells. ABSTRACT We introduce a novel approach for the control of oligonucleotides through

Fluorescent Carbazole‐derived Aza[5]helicenes: Synthesis, Functionalization, and Characterization

open access: yesChemistry – A European Journal, Accepted Article.
5,8‐Dihydroindolo[2,3‐c]carbazole (ICz), 9H‐cinnolino[3,4‐c]carbazole (CnCz), and variously alkyl‐, alkenyl‐, and aryl‐substituted indolo[2,3‐k]‐ and ‐[3,2‐a]phenanthridines (IPs) were synthesized using an ortho fusion strategy with Suzuki cross couplings, intramolecular nitrene insertions, diazo couplings, and Morgan‐Walls cyclizations as key ...

Actin Filament Pointed Ends: Assays for Regulation of Assembly and Disassembly by Tropomodulin and Tropomyosin

open access: yesCytoskeleton, EarlyView.
ABSTRACT Actin filaments are dynamic polymers whose length depends on regulated monomer association and dissociation at their ends. Actin barbed‐end dynamics are relatively better understood, primarily due to the approximately tenfold faster subunit on/off rates at barbed versus pointed ends.

Hemoglobin D is the Commonest Hemoglobinopathy in the North of Iran

open access: yesMedical Laboratory Journal, 2015
Background and Objective: Normal hemoglobin (Hb) is formed of a heme group and a protein group known as globin. Globin is made of four polypeptide chains and in hemoglobinopathies, the structure of one of these four polypeptide chain becomes abnormal ...
