The review of the results of fundamental physical, chemical and biological studies proposed to be used in the program for elaboration methods of biological nitric oxide (NO) dosimetry is presented. Particular attention was paid to the structures of dinitrosyl iron complexes (DNIC). The review includes subsection: target of NO in the cell; DNIC function in biology and medicine; DNIC--the largest pool of intracellular iron; EPR signal g = 2.03 - DNIC indicator, and the value of O2 in the biological activity of DNIC, quantification of nitric oxide. Experimental evidences of the advantages of using EPR spectroscopy of E. coli cells--with identification of the value and structure of DNIC signals (signal g = 2.03) as a direct method of biological NO dosimetry are presented. The strong emphasis was made on the priority of the Russian School--Professor Vanin A. F. (the discovery and study of DNIC) and Academician Aldoshin S. M. (synthesis and study of crystalline donor NO).

In chronic kidney disease (CKD), hyperuricemia is a common phenomenon, presumably due to reduced renal clearance of uric acid. This study investigated the effect of xanthine oxidase (XO) inhibitors allopurinol and febuxostat to prevent oxidative stress in the kidney of two-kidney, one-clip (2K1C) rats. In this investigation, 2K1C rats were used as an experimental animal model for kidney dysfunction.

We previously demonstrated that the inability of primary endothelial cilia to sense fluid shear stress can lead to nitric oxide (NO) deficiency and cause hypertension (HTN). Decreased biosynthesis of NO contributes to cerebral amyloid angiopathy in Alzheimer's disease (AD) patients through increased deposition of amyloid beta (Aβ). However, the molecular mechanisms underlying the pathogenesis of HTN and AD are incompletely understood.

Background: Monovalent biologics blocking thymic stromal lymphopoietin or interleukin-13 have been shown to elicit pharmacodynamic responses in asthma following a single dose. Therefore, dual blockade of these cytokines may result in an enhanced response compared to single targeting and has the potential to break efficacy ceilings in asthma. This study assessed the safety and tolerability of lunsekimig, a bispecific NANOBODY molecule that blocks thymic stromal lymphopoietin and interleukin-13, and its effect on Type 2 inflammatory biomarkers and lung function in asthma.
