In contrast, there was no reaction of body temperature to greater (6-10 nT) but irregular and abrupt perturbations of GMF.We studied ultrastructure and vesicular structures in endothelial cells of myocardial micro-vessels in burn patients. Electron microscopy revealed a significant decrease in volume density of vesicular structures in the endotheliocytes of myocardial capillaries in patients with burn septicotoxemia. The observed structural signs of endothelial dysfunction revealed in this category of patients can be a promising area for further research and for the development of methods of pathogenetic correction of myocardial disorders in the case of burn injury.Intact Disc1-L100P mice carrying a point mutation DISC1Rgsc1390 in the second exon of the DISC1 gene (genetic model of schizophrenia) differ from the parental C57BL/6NCrl strain by higher content of CD3+ T cells and reduced number of CD19+B cells in the peripheral blood and spleen. Lithium Chloride cost Analysis of T cell subpopulations revealed an increase in the number of CD3+CD4+ T helpers in the blood of mutant mice and a decrease in the level of CD3+CD8+ suppressor/cytotoxic T cells and CD3+CD4+CD25+ T-regulatory cells. The distribution pattern of inflammatory (IL-1β, IL-2, IL-6, IL-17, IFNγ, and TNFα) and anti-inflammatory (IL-4, IL-10) cytokines specific for Disc1-L100P mice was revealed in the brain structures involved in the pathogenesis of schizophrenia. A possible implication of immune mechanisms in the development of schizophrenia-like endophenotype of Disc1-L100P mice is discussed.To better explore the pathophysiology of FA and its therapy, we aimed to establish a simple and practicable FA model with Freund's adjuvant and introduce an easy and reliable laboratory evaluation method for assessment of inflammation in intestinal segments at different anatomical locations. BALB/c mice were sensitized with ovalbumin combined with Freund's adjuvant. Complete Freund's adjuvant was chosen for the first sensitization and two weeks later incomplete Freund's adjuvant was used for a second sensitization. Two weeks later, the sensitized mice were challenged with 50 mg ovalbumin every other day. After the 6 challenge, all mice were assessed for systemic anaphylaxis, and then sacrificed for sample collection. All sensitized mice showed anaphylactic symptoms and markedly increased levels of serum ovalbumin-specific IgE and IgG1. The activity of mast cell protease-1 (mMCPT-1) was significantly increased in the serum and interstitial fluid of the duodenum, jejunum, ileum, and colon. A successful FA model was established, of which inflammation occurred in the duodenum, jejunum, ileum, and colon. This model provides a reliable and simple tool for analysis of the mechanism of FA and methods of immunotherapy. Moreover, combined detection of ovalbumin-specific antibody and local mMCPT-1 levels could potentially be used as the major indicator for assessment of food allergy.We performed comparative analysis of 8-hydroxy-2'-deoxyguanosine in women in different climax stages with and without insomnia. The study involved 90 women aged 45 to 60 years divided into perimenopausal (n=30) and postmenopausal (n=60) groups. After questioning using special sleep questionnaires (Insomnia Severity Index, Epworth Sleepiness Scale, Munich Chronotype Questionnaire), the groups were divided into subgroups with insomnia and without it (control). 8-Hydroxy-2'-deoxyguanosine was assayed in blood serum by ELISA. The higher levels of 8-hydroxy-2'-deoxyguanosine in postmenopausal women with insomnia in comparison with the control and perimenopausal patients (p less then 0.05) attested to oxidative DNA damage in this cohort of patients.We analyzed interrelations between the cerebral blood flow, cardiac output, and condition of the brain substance in 530 patients with ischemic stroke. Dependencies between the linear blood flow velocities in all arteries supplying the brain, as well as between the total volume blood flow through the internal carotid arteries and left ventricular stroke volume were revealed. The severity of atrophy was maximum in the parietal lobes (median 1.5 (1.0; 2.0)) and minimum in the occipital lobes (median 0.5 (0; 1.0)). Temporal lobes cortical atrophy significantly correlated with changes in the limbic system and in the periventricular and deep white matter; a significant weak inverse correlation of this parameter with blood flow in the middle cerebral artery was also found. Changes in the periventricular white matter (but not in deep white matter) demonstrated a significant inverse correlation with blood flow in the middle and anterior cerebral arteries.We studied the participation of JNK and p53 in the realization of the growth potential of different types of progenitors of the subventricular zone of mouse brain and secretion of neurotrophins by glial cells. The stimulating role of these signaling molecules in mitotic activity and specialization of multipotent neural stem cells was shown. It was found that JNK and p53 do not participate in the regulation of committed neuronal progenitor cells (clonogenic PSA-NCAM+ cells). A dependence of neurotrophic growth factors in individual populations of neuroglia on activity of these protein kinase and transcription factor was revealed. The role of JNK and p53 in astrocytes consists in stimulation of their secretion, and in microglial cells, on the contrary, in its inhibition. The secretory neurotrophic function of oligodendrogliocytes is not associated with JNK and p53 activity.For correct and reliable experimental in vivo assessment of antistress effect of various bioactive substances, appropriate biomodels reproducing stress and organism response to stress in laboratory animals should be chosen. We chose treadmill test for simulating exhaustive physical load and forced immobilization accompanied by disorders of physiological and psychological condition. Verification of the models used indicates their wide applicability for testing certain biological manifestations under reproduced stress exposure.Combined treatment of murine leukemia P388 with doxorubicin and platinum(IV)-nitroxyl complex ВС118 administered in low doses improved efficiency of treatment (cure of 83% of animals) without increasing toxicity.We studied the effect of technogenic radiation on the degree of promoter methylation in genes involved in apoptosis in blood lymphocytes of workers exposed to long-term γ-radiation during their professional activities. Blood samples for the analysis were obtained from 11 conventionally healthy men aged from 54 to 71 years (mean 66 years), workers of the Siberian Group of Chemical Enterprises working experience from 27 to 40 years (mean 30 years); the external exposure dose was 175.88 mSv (158.20-207.81 mSv). In all examined subjects, the degree of methylation of the promoters of apoptosis-related genes ranged from 0.22 to 50.00%. A correlation was found between the degree of methylation of BCLAF1 promoters (p=0.035) with the age of workers, BAX promoters (p=0.0289) with high content of aberrant cells, and APAF1 promoters (p=0.0152) with increased number of dicentric chromosomes. A relationship was found between the dose of external irradiation and the degree of methylation of gene promoters of BAD (p=0.0388), BID (р=0.0426), and HRK (р=0.0101) genes.The brain mechanisms underlying conditioned aversion learning in birds were studied using experimental model in young chicks. The learning consisted of a conditioning stimulus presentation followed by a delayed sickness-inducing treatment reinforcement. Intraventricular administration of an NMDA receptor antagonist MK-801, a protein synthesis inhibitor anisomycin, or an inhibitor of glycoprotein fucosylation 2-deoxygalactose just before presentation of the conditioning stimulus prevented aversion learning. Injections of the same chemicals before reinforcement did not affect learning. The obtained results show that the investigated mechanisms underlying aversion learning were critical at the early stage of memory formation. Later processes of association of the conditioning stimulus with the reinforcement appear to be independent of the NMDA receptors and protein synthesis/glycosylation, or alternatively to be located in other brain areas.The neurotrophic properties of magnesium comenate were studied under standard conditions and under conditions of oxidative stress. It was found that magnesium comenate has a stimulating effect on the neurotrophic processes of the spinal ganglia under normal conditions and under conditions of oxidative stress. Under standard conditions, magnesium comenate exhibits neurotrophic activity at a concentration of 0.0001 mM, under conditions of oxidative stress, magnesium comenate exhibits neurotrophic activity at concentration 0.1 mM.We examined 74 patients with acute decompensation of alcoholic liver cirrhosis 34 (45.9%) with bacterial infection (group 1) and 40 (54.1%) without bacterial infection (group 2). The degree and index of acute-on-chronic liver failure (ACLF) were determined using an on-line CLIF-C ACLF Calculator and the levels of cytokeratin-18 fragments, TNFα, IL-1β, IL-4, IL-6, and IL-8. In group 1, AST, cytokeratin-18, TNFα, IL-1β, IL-6, degree and score of ACLF were significantly higher than in group 2. ACLF developed in 18 (52.9%) patients in group 1 and in 11 (27.5%) (p less then 0.05) patients in group 2. Within 1 month, 10 (29.4%) patients of group 1 and 2 (5%) patients of group 2 died (p less then 0.05). Patients with bacterial infection showed a more severe course of alcoholic liver cirrhosis and ACLF than those without bacterial infection.Botulism is a rare, acute, life-threatening neuro-paralysis. The digestive onset may raise diagnostic issues. The objective of our study was to analyze the clinical and epidemiological data of patients diagnosed with botulism and hospitalized in "Gavril Curteanu" Municipal Clinical Hospital (Oradea, Romania). Detection of the Clostridium botulinum neurotoxin (type B) in the laboratories of the National Institute of Medical-Military Research Development "Cantacuzino", Bucharest, Romania (using the mouse bioassays method) confirmed the diagnostics. The statistical analysis was performed using the IBM SPSS software. Forty-eight patients with the diagnosis of foodborne botulism were hospitalized between 2012 and 2018 (36.92% of the total number of cases of botulism reported in Romania). The winter-spring period was the period when most cases were registered (36 patients, p=0.020). Women from rural areas were predominant (but not statistically significant), and the patients' mean age was 39.93±12.59 years. The most common source/cause of botulism was the consumption of homemade ham. The incubation period was 26.68±22.94 h, and 2.25±1.68 days passed from the clinical onset to diagnosis. The results prove that botulism is still a public health issue, especially in areas where homemade products are prepared using inappropriate/unsafe recipes/procedures.Parenting by lying is a phenomenon in which parents lie to their children, usually for a positive goal, and has been the subject of new parenting research. This study tested the associations between parenting by lying in childhood, lying to parents in young adulthood, and parent-child relationship quality. Secondly, we examined the mechanisms through which these constructs were all related to internalizing behaviors in young adulthood, specifically-stress, anxiety and depressive symptoms. Young adult participants between the ages of 18 and 24 (N = 206) responded to questions about parenting strategies experienced in childhood, their current adult functioning, lying to parents, and parent-child relationship quality. Results indicate that parenting by lying in childhood was significantly associated with lower quality relationships with parents during young adulthood. Additionally, we found that double mediation models (lying to parents and quality of parent-child relationships) were best fitting the data in explaining the exploratory mechanisms (indirect pathways) through which parenting by lying was associated with internalizing behaviors (stress responses, anxiety, and depressive symptoms) in young adulthood.
