From studies on the effects of “high dilutions” on organisms, it was found that their administration induces a delicate physiological (molecular and cellular) response. Occasionally, physiological reactions can become atypical (pathological) individual reactions. To resolve this paradox, the spatial homeostasis hypothesis has been proposed. It considers pathological processes as tools used by living systems, in order to retain their spatial integrity (symmetry), allowing them to properly reflect the geometry of the surrounding world and thus, to be a part of the evolutionary process. This article addresses an interdisciplinary subject and is aimed at natural scientists (physicists, chemists, and biologists) as well as philosophers.

Vascular cognitive impairment (VCI) and vascular dementia are the most common forms of cognitive disorder associated with cerebrovascular disease and related to increased morbidity and mortality among the older population. Growing evidence suggests the contribution of blood-pressure variability, cardiac arrhythmia, hyperactivation of the renin–angiotensin–aldosterone system, endothelial dysfunction, vascular remodeling and stiffness, different angiopathies, neural tissue homeostasis, and systemic metabolic disorders to the pathophysiology of VCI. In this review, we focus on factors contributing to cerebrovascular disease, neurovascular unit alterations, and novel approaches to cognitive improvement in patients with cognitive decline. One of the important factors associated with the neuronal causes of VCI is the S100B protein, which can affect the expression of cytokines in the brain, support homeostasis, and regulate processes of differentiation, repair, and apoptosis of the nervous tissue. Since the pathological basis of VCI is complex and diverse, treatment affecting the mechanisms of cognitive disorders should be developed. The prospective role of a novel complex drug consisting of released–active antibodies to S100 and to endothelial NO synthase in VCI treatment is highlighted.

The study was aimed to investigate the effect of technologically treated diclofenac (release-active dilutions of diclofenac (RAD of diclofenac)) on anti-inflammatory activity of diclofenac in carrageenan-induced rat paw edema model. Ninety male Wistar albino rats (6–8 weeks) divided into nine groups (n = 10) were used. Anti-inflammatory activity was assessed at 1, 2, 3, 4, and 6 h after subplantar injection of carrageenan (0.1 ml of a 1 % solution in normal saline). Diclofenac alone was studied at 5 and 20 mg/kg, RAD of diclofenac alone at 7.5 ml/kg and their combination at 5 and 7.5 ml/kg, respectively. Diclofenac reduced (p < 0.05 at least) paw edema at all time points. RAD of diclofenac enhanced (p < 0.05) anti-inflammatory effect of diclofenac (5 mg/kg) at 2, 4, and 6 h on concurrent and at 2 and 4 h on sequential administration. Moreover at 2 h, anti-inflammatory effect of combination treatment reached values comparable to those of diclofenac (20 mg/kg). In conclusion, RAD of diclofenac enhanced anti-inflammatory effect of diclofenac.

In preliminary ELISA studies where released-active forms (RAF) of antibodies (Abs) to interferon-gamma (IFNg) were added to the antigen-antibody system, a statistically significant difference in absorbance signals obtained in their presence in comparison to placebo was observed. A piezoelectric immunosensor assay was developed to support these data and investigate the effects of RAF Abs to IFNg on the specific interaction between Abs to IFNg and IFNg. The experimental conditions were designed and optimal electrode coating, detection circumstances and suitable chaotropic agents for electrode regeneration were selected. The developed technique was found to provide high repeatability, intermediate precision and specificity. The difference between the analytical signals of RAF Ab samples and those of the placebo was up to 50.8%, whereas the difference between non-specific controls and the placebo was within 5%–6%. Thus, the piezoelectric immunosensor as well as ELISA has the potential to be used for detecting the effects of RAF Abs to IFNg on the antigen-antibody interaction, which might be the result of RAF’s ability to modify the affinity of IFNg to specific/related Abs.
