The authors conducted clinical and immunological research on the identification of сytokine factors of inflammation and regeneration in patients with frontal bone trauma (29) and practically healthy donors (11). Factors of inflammation (interleukin-1β, γ-interferon), anti-inflammation and regeneration (interleukin-34 and transforming growth factor – TGF-1β) were determined in the blood serum by ELISA. It was found that the content of the factor of regeneration decreases and the levels of anti-inflammatory cytokines increase in the blood serum of the patients with frontal traumas with frontal sinus damage.

Abstract Multiple myeloma (MM) is a serious disease that is difficult to diagnose especially at early stage. Infrared spectroscopy is a promising approach for diagnosing MM. The principal component analysis (PCA) allows us to reduce the dimension of the data and keep only the important variables. In this study, we apply principal components analysis to infrared (IR) spectra of blood serum from healthy donors and multiple myeloma patients. As a result of the analysis by PCA, it was possible to visualize the separation of patient’s and donor’s samples into two clusters. The result indicates that this method is potentially applicable for diagnosis of multiple myeloma.

The concentrations of matrix metalloproteinases (MMP-2, -3, -9) and their tissue inhibitors (TIMP-1, -2) were studied in blood serum of 193 patients with squamous cell head and neck carcinoma (SCHNC) and in 38 healthy donors using immunoenzymatic assay. The decreased MMP-3 and TIMP-1, -2 levels were found in patients with oral cavity tumors as compared to patients with laryngeal cancer. The serum MMP-9 and TIMP-1 levels were significantly higher in head and neck cancer patients than in healthy subjects. High TIMP-1 and MMP-9 levels in blood serum of patients with SCHNC should be greatly attended for detection of their predictive and prognostic significances.

The data of a comparative enzyme-linked immunosorbent assay of the content of the soluble form of the immunity checkpoint VISTA in the blood serum of 30 healthy donors (control group), 79 patients with primary malignant (osteosarcoma - 30, chondrosarcoma - 31, chordoma - 14) and 14 borderline (giant cell tumor) bone neoplasms are presented. In the general group of patients with malignant neoplasms of bones, the median sVISTA content in blood serum is statistically significant lower than in the control (p = 0.040). In patients with bone tumors and healthy donors over 18 years of age, there was a decrease with age in serum sVISTA levels. There were no significant differences in sVISTA concentration between patients with osteosarcoma, chondrosarcoma and healthy donors. Only in patients with chordoma were sVISTA levels statistically significant lower than in controls (p = 0.013). In the groups of patients with chondrosarcoma and osteosarcoma of the bone, there were no significant associations between the serum sVISTA content and the main clinical and morphological characteristics of the disease. In patients with osteosarcoma, no relationship was found between sVISTA levels and overall survival rates, while in patients with bone chondrosarcoma, there was a tendency towards a favorable prognosis with a high content of the marker in the blood serum.

Determination of the concentration and size of the circulating immune complexes in the blood is an essential part of diagnostics of immune diseases. In this work, we suggest using the dynamic light scattering method to determine the sizes of circulating immune complexes in blood serum. By the dynamic light scattering spectrometer, we found that for healthy and sick donors, the size and concentration of circulating immune complexes differed significantly. The dynamics of formation of these complexes were also examined in this work. It was shown that the formation of immune complexes in the blood of healthy donors is faster than the same reactions in the blood serum of donors with diseases. The results can be used in the diagnostics of the immune status and detection of chronic inflammation. We can recommend the dynamic light scattering method for implementation in biomedical diagnostics.

The level and change in concentration of trace elements in the fluids of a body may be the result and an evidence of alterations in life functions. In the search for trace element alterations in the human body it is necessary to know referenced values for as many elements as possible. In this work, Proton Induced X-ray Emission (PIXE) was used to study elemental concentrations in human blood serum of 30 healthy donors. The serum samples were obtained by centrifugation and were micro-pipetted on 10µm thick Nuclepore film for PIXE analysis. The elemental concentrations were calculated relative to an internal yttrium standard added during sample preparation. A total of 9 elements were measured (P, S, Cl, K, Ca, Fe, Cu, Zn and Br) in good agreement with literature data. The accuracy of the method was verified analysing reference serum samples from the NIPH-Québec (ICP04S-06 and ICP02S-05). A preliminary statistical analysis indicated a log-normal distribution only for Fe and Cu, while concentration data for the other elements followed the normal distributions. This result indicates the need for stronger statistical data set since the distribution of the elemental concentrations may be a criterion to access their role in biological functions.

The Right

Four decades ago, immunological research was dominated by the field of lymphoid biology. It was commonly accepted that multicellular eukaryotes defend themselves through phagocytosis. The lack of lymphoid cells in insects and other simpler animals, however, led to the common notion that they might simply lack the capacity defend themselves with humoral factors. This view was challenged by microbiologist Hans G. Boman and co-workers in a series of publications that led to the advent of antimicrobial peptides as a universal arm of the immune system. Besides ingenious research, Boman ignited his work by posing the right questions. He started off by asking himself a simple question: ‘Antibodies take weeks to produce while many microbes divide hourly; so how come we stay healthy?’. This led to two key findings in the field: the discovery of an inducible and highly potent antimicrobial immune response in Drosophila in 1972, followed by the characterization of cecropin in 1981. Despite broadly being considered an insect-specific response at first, the work of Boman and co-workers eventually created a bandwagon effect that unravelled various aspects of innate immunity. This article is part of the themed issue ‘Evolutionary ecology of arthropod antimicrobial peptides’.
