In the review we analyzed short history of the establishment of a novel hematological parameter for systemic inflammation and stress coined as a neutrophil to lymphocyte ratio (NLR). Today NLR is widely used across almost all medical disciplines as a reliable and easy available marker of immune response to various infectious and non-infectious stimuli. We analyzed the immunological and biological aspects of dynamic changes of neutrophil granulocytes and lymphocytes in circulating blood during endocrine stress, dysbalance of autonomic nervous system and systemic inflammation. ⋯ Dynamic changes of NLR precede the clinical state for several hours and may warn clinicians about the ongoing pathological process early. NLR is a novel perspective marker of cellular immune activation, a valid index of stress and systemic inflammation, which open a new dimension for clinical medicine, for better understanding of the biology of inflammation, coupling and antagonism between innate and adaptive immunity and its clinical consequences for health and disease (Tab. 8, Fig. 3, Ref. 151). Keywords: neutrophil-to-lymphocyte ratio, systemic inflammation, immune-inflammatory response, endocrinne stress.

The studies to prevent the Corona virus, which is a huge epidemic nowadays and causes the death of many people, are of great importance. Drugs to be developed to prevent the proliferation and spread of it. The active substances of the drugs have been used to prevent the attack of the COVID-19. The natural phytochemicals obtained from the traditional medicine play a big role in the inhibition of functional structures in many harmful microscopic structures. ⋯ This study is the first in terms of reducing the harmful effect of COVID-19 by providing effective results in a short time by guiding the experimental studies to reveal the inhibitory effect of COVID-19 (Tab. 3, Fig. 5, Ref. 25). Text in PDF www.elis.sk Keywords: COVID-19, Carvacrol, docking Cucurbitacin-E and I.

Epithelial cells and macrophages play major roles in modulating the state of inlammatory response regulated by intracellular signaling pathways. The aim of this study was to characterize changes in cell proliferation, apoptosis and inflammation related intracellular signalling pathways MAPKs and NF-κB in Caco-2 epithelial cells and THP-1 macrophage-like monocytes contacted and filter-seperated co-cultures in the presence of LPS stimulation. ⋯ Epithelia - monocytes co-culture stimulated with LPS regulated cell proliferation and inflammation in a contact dependent manner, whereas apoptosis was associated with non-contacted cell culture condition. Thus, co-culture models are important models for explaining the immunopathologies in the mucosal areas (Fig. 5, Ref. 30).

The aim of this study was to investigate the association of RDW with all-cause mortality and disease progression in patients with CKD in stage 3-4. ⋯ RDW is a powerful and independent prognostic marker for predicting all-cause mortality and disease progression in stage 3-4 of CKD (Tab. 4, Fig. 4, Ref. 29).

Seven dioxaborole compounds are investigated in this study. Structural and spectral characterizations are done at the M062X/6-31+G(d,p) level in water. Active sites of these compounds are determined by contour plots of frontier molecular orbital and molecular electrostatic potential (MEP) maps. Electrophilic and nucleophilic attack regions are determined. Since SARS-CoV-2 is a worldwide health problem, antiviral properties of studied boron-containing compounds are investigated by molecular docking calculations. In addition to these calculations, MM/PSBA calculations are performed. ⋯ It is found that the studied boron compounds can be good drug candidates against the main protease of SARS-CoV-2, while the best of them is 4,6-di-tert-butyl-2-(4-methoxyphenyl)benzo[d][1,3,2] dioxaborole (B2) (Tab. 3, Fig. 8, Ref. 23).
