Abstract Lipids are biomolecules present in all living organisms that, apart from their physiological functions, can be involved in different pathologies. One of these pathologies is fat embolism, which has been described histologically in the lung of cetaceans in association with ship strikes and with gas and fat embolic syndrome. To assess pathological lung lipid composition, previous knowledge of healthy lung tissue lipid composition is essential; however, these studies are extremely scarce in cetaceans. In the present study we aimed first, to characterize the lipids ordinarily present in the lung tissue of seven cetacean species; and second, to better understand the etiopathogenesis of fat embolism by comparing the lipid composition of lungs positive for fat emboli, and those negative for emboli in Physeter macrocephalus and Ziphius cavirostris (two species in which fat emboli have been described). Results showed that lipid content and lipid classes did not differ among species or diving profiles. In contrast, fatty acid composition was significantly different between species, with C16:0 and C18:1ω9 explaining most of the differences. This baseline knowledge of healthy lung tissue lipid composition will be extremely useful in future studies assessing lung pathologies involving lipids. Concerning fat embolism, non-significant differences could be established between lipid content, lipid classes, and fatty acid composition. However, an unidentified peak was only found in the chromatogram for the two struck whales and merits further investigation.

AbstractLung ventilation and perfusion analyses using chest imaging methods require a correct segmentation of the lung to offer anatomical landmarks for the physiological data. An automatic segmentation approach simplifies and accelerates the analysis. However, the segmentation of the lungs has shown to be difficult if collapsed areas are present that tend to share similar gray values with surrounding non-pulmonary tissue. Our goal was to develop an automatic segmentation algorithm that is able to approximate dorsal lung boundaries even if alveolar collapse is present in the dependent lung areas adjacent to the pleura. Computed tomography data acquired in five supine pigs with injured lungs were used for this purpose. First, healthy lung tissue was segmented using a standard 3D region growing algorithm. Further, the bones in the chest wall surrounding the lungs were segmented to find the contact points of ribs and pleura. Artificial boundaries of the dorsal lung were set by spline interpolation through these contact points. Segmentation masks of the entire lung including the collapsed regions were created by combining the splines with the segmentation masks of the healthy lung tissue through multiple morphological operations. The automatically segmented images were then evaluated by comparing them to manual segmentations and determining the Dice similarity coefficients (DSC) as a similarity measure. The developed method was able to accurately segment the lungs including the collapsed regions (DSCs over 0.96).

Background: The respiratory system is one of the main entrance gates for infection. The aim of this work was to compare the appearance of specific mucosal pro-inflammatory and common anti-microbial defence factors in healthy lung tissue, from an ontogenetic point of view. Materials and methods: Healthy lung tissues were collected from 15 patients (three females and 12 males) in the age range from 18 to 86. Immunohistochemistry to human β defensin 2 (HBD-2), human β defensin 3 (HBD-3), human β defensin 4 (HBD-4), cathelicidine (LL-37) and interleukine 17A (IL-17A) were performed. Results: The lung tissue material contained bronchial and lung parenchyma material in which no histological changes, connected with the inflammatory process, were detected. During the study, various statistically significant differences were detected in immunoreactive expression between different factors in all lung tissue structures. Conclusion: All healthy lung structures, but especially the cartilage, alveolar epithelium and the alveolar macrophages, are the main locations for the baseline synthesis of antimicrobial proteins and IL-17A. Cartilage shows high functional plasticity of this structure, including significant antimicrobial activity and participation in local lung protection response. Interrelated changes between antimicrobial proteins in different tissue confirm baseline synergistical cooperation of all these factors in healthy lung host defence.

AbstractThrough considerable effort in research and clinical studies, the immune system has been identified as a participant in the onset and progression of brain injury after ischaemic stroke. Due to the involvement of all types of immune cells, the roles of the immune system in stroke pathology and associated effects are complicated. Past research concentrated on the functions of monocytes and neutrophils in the pathogenesis of ischaemic stroke and tried to demonstrate the mechanisms of tissue injury and protection involving these immune cells. Within the past several years, an increasing number of studies have elucidated the vital functions of T cells in the innate and adaptive immune responses in both the acute and chronic phases of ischaemic stroke. Recently, the phenotypes of T cells with proinflammatory or anti-inflammatory function have been demonstrated in detail. T cells with distinctive phenotypes can also influence cerebral inflammation through various pathways, such as regulating the immune response, interacting with brain-resident immune cells and modulating neurogenesis and angiogenesis during different phases following stroke. In view of the limited treatment options available following stroke other than tissue plasminogen activator therapy, understanding the function of immune responses, especially T cell responses, in the post-stroke recovery period can provide a new therapeutic direction. Here, we discuss the different functions and temporal evolution of T cells with different phenotypes during the acute and chronic phases of ischaemic stroke. We suggest that modulating the balance between the proinflammatory and anti-inflammatory functions of T cells with distinct phenotypes may become a potential therapeutic approach that reduces the mortality and improves the functional outcomes and prognosis of patients suffering from ischaemic stroke.

The pineal gland produces the important hormone melatonin, the level of which in the blood of pregnant women decreases in case of placental insufficiency. The effect of dysfunction of the pineal gland on the immune system of pregnant women and on the angiogenic activity of the placenta during pregnancy remains insufficiently studied. Objective: to establish the effect of our method of non-drug correction of function of pineal gland on the state of the cytokine part of the immune system and on the synthesis of placental growth factor (PlGF) in pregnant women with placental insufficiency manifesting as fetal intrauterine growth restriction (IUGR). Material and methods. 46 pregnant women with IUGR at 30-36 weeks of gestation were examined. The group was divided into two subgroups: with non-drug correction of the pineal gland function (n = 25) and without correction (n = 21). The method of correction included a set of measures of following of lighting regimen, activity and sleep for 14 days. The control group consisted of 20 women with uncomplicated pregnancy. Levels of melatonin, PlGF, TNF-α, IL-1β, IL-6, IL-4, IL-10 were determined in the venous blood by enzyme-linked immunosorbent assay. Results. It was established that the concentration of melatonin in the blood of pregnant women with IUGR was significantly reduced, as well as the concentration of PlGF (p < 0.01). Significant changes were also found in pregnant women with placental insufficiency, namely, increased concentrations of proinflammatory cytokines, such as TNF-α (p < 0.05), IL-1-β (p < 0.001) and IL-6 (p < 0.05), comparing to healthy pregnant women. Also, in the group of pregnant women with IUGR the levels of anti-inflammatory cytokines IL-4 (p <0.001) and IL-10 (p < 0.001) were elevated in comparison to the control group. After application of the developed complex of non-drug correction of pineal gland function, the concentration of melatonin in the blood of pregnant women in the subgroup of correction increased significantly, comparing to the subgroup without correction (p < 0.001), as well as the level of PlGF (p < 0.05). Also, significantly lower levels of proinflammatory cytokines TNF-α, IL-1-β and IL-6 were observed in pregnant women in the subgroup of correction (p < 0.01). Regarding anti-inflammatory cytokines, under the influence of the developed complex of measures there was a decrease in the level of IL-4 and an increase in the level of IL-10 (p < 0.01). Conclusions. When the measures, aimed at non-drug correction of function of pineal gland, are applied in pregnant women with placental insufficiency, manifested as IUGR, the following changes are observed: increased of plasma levels of melatonin and placental growth factor, decreased of levels of proinflammatory cytokines. We suggest that the pineal gland exerts its effect on the immune system through melatonin, which moderates the activity of pro- and anti-inflammatory cytokines, thereby reducing the influence of inflammation on placental tissue, what results in increasing of concentrations of placental growth factor in the blood of pregnant women.
