Background. Endogenous intoxication is a multicomponent complex process due to the endogenous biological products or dysfunction of systemic natural detoxification. Objective. The aim of the research was to study the dynamics of indices of endogenous intoxication in rats with traumatic muscle damage in the experiment. Methods. The experiment was performed on 45 non-linear white rats, which were modeled with traumatic muscle damage. The level of endogenous intoxication was assessed by the content of medium plasma molecules (MMM), leukocyte and erythrocytic index of intoxication (LII and EII). The research was conducted on the 1st, 3rd, 7th, 14th days after the injury. Results. It was found that traumatic muscle damage causes endotoxemia. Manifestations of endogenous intoxication are: the increase of MMM1 in 2.3 times, MMM2 in 2.8 times compare to the intact animals. The level of this indicator slightly decreased in 7 days. Simultaneously with an increase in the MCT level in the post-traumatic period, the total toxic effect on the erythrocyte membrane also increased, which was manifested by a significant increase in EII in all terms of observation. Conclusions. Traumatic damage of the muscles is accompanied by the growth of molecules of average mass in upto 7 days of observation, which significantly differ from the indicators of the intact group. The results of our research prove that traumatic muscle damage causes endotoxicosis development evidenced by accumulation of endotoxins in the animals’ body that is proved by significant changes in endogenous intoxication indices: i.e. erythrocytic and leukocytic indexes of intoxication and content of medium mass molecules.

The Relationship

The article presents the results of studies to identify the role of endogenous intoxication in the pathogenetic mechanisms of heat stress in cows in a comparative aspect between healthy animals and animals with hepatopathology. The obtained data indicate that in summer period in a farm located on the flat territory of the Krasnodar region the cattle are influenced by the heat stress. The relationship between the state of moderate heat stress in dairy cattle and the dynamics of a number of indicators characterizing the syndrome of endogenous intoxication of their body was revealed. The increase in the concentration of medium mass molecules (MMM) in healthy livestock was almost two times lower than in animals with fatty hepatosis. The obtained results can serve as a rationale for the development of an effective strategy for pharmacological correction of heat stress in cattle.

Positive Effect

Eye Movement Desensitization and Reprocessing (EMDR) is a treatment for post-traumatic stressdisorder (PTSD). The technique is known to stimulate the capacity to reprocess maladaptive memoriesthat are thought to be central to this pathology. Here we investigate if EMDR therapy can be used in otherconditions than PTSD. We conducted a systematic literature search on PubMed, ScienceDirect, Scopus, and Web of Science. Wesearched for published empirical findings on EMDR, excluding those centred on trauma and PTSD,published up to 2020. The results were classified by psychiatric categories.   Ninety articles met our research criteria. A positive effect was reported in addictions, somatoformdisorders, sexual dysfunction, eating disorder, disorders of adult personality, mood disorders, reaction tosevere stress, anxiety disorders, performance anxiety, Obsessive-Compulsive Disorder (OCD), pain,neurodegenerative disorders, paedopsychiatry and sleep. The evidence was more consistent in pain, OCD,mood disorders, and reaction to severe stress.EMDR’s efficiency across numerous pathological situations, highlighted the central role of affectivememory in several psychiatric and non-psychiatric conditions. Furthermore, EMDR seems to besuccessful in usually uncooperative (e.g. Dementia) or unproductive cases (e.g. aphasia). Moreover, insome severe medical situations were psychologic distress was an obstacle, EMDR allowed thecontinuation of treatment-as-usual. Our review suggests that it is a safe and economical therapeuticoption, and its effect in non-pathological situations opens new avenues for translational research. Overallmore methodologically rigorous studies are needed.

When the Gothic War began in Italy in 535, the country still conserved many features of classical culture and late antique administration. Much of that was lost in the political upheavals of the following decades. Building on Chris Wickham’s work, this contribution sketches an integrated perspective of these changes, attempting to relate the contingency of events to the logic of long-term change, discussing political options in relation to military and economic means, and asking in what ways the erosion of consensus may be understood in a cultural and religious context. What was the role of military entrepreneurs of more or less barbarian or Roman extraction in the distribution or destruction of resources? How did Christianity contribute to the transformation of ancient society? The old model of barbarian invasions can contribute little to understanding this complex process. It is remarkable that for two generations, all political strategies in Italy ultimately failed.

Cortisol Release

Under stressful conditions, the hypothalamic-pituitary-adrenal (HPA) axis acts to promote transitory physiological adaptations that are often resolved after the stressful stimulus is no longer present. In addition to corticosteroids (e.g., cortisol), the neurosteroid allopregnanolone (3α,5α-tetrahydroprogesterone, 3α-hydroxy-5α-pregnan-20-one) participates in negative feedback mechanisms that restore homeostasis. Chronic, repeated exposure to stress impairs the responsivity of the HPA axis and dampens allopregnanolone levels, participating in the etiopathology of psychiatric disorders, such as major depressive disorder (MDD) and post-traumatic stress disorder (PTSD). MDD and PTSD patients present abnormalities in the HPA axis regulation, such as altered cortisol levels or failure to suppress cortisol release in the dexamethasone suppression test. Herein, we review the neurophysiological role of allopregnanolone both as a potent and positive GABAergic neuromodulator but also in its capacity of inhibiting the HPA axis. The allopregnanolone function in the mechanisms that recapitulate stress-induced pathophysiology, including MDD and PTSD, and its potential as both a treatment target and as a biomarker for these disorders is discussed.

AbstractThe persistence of anxiety and the deficit of fear memory extinction are both phenomena related to the symptoms of a trauma-related disorder, such as post-traumatic stress disorder (PTSD). Recently we have shown that single acute restraint stress (2 h) in rats induces a late anxiety-related behavior (observed ten days after stress), whereas, in the present work, we found that the same stress impaired fear extinction in animals conditioned ten days after stress. Fourteen days of environmental enrichment (EE) prevented the deleterious effect of stress on fear memory extinction. Additionally, we observed that EE prevented the stress-induced increase in AMPA receptor GluA1 subunit phosphorylation in the hippocampus, but not in the basolateral amygdala complex and the frontal cortex, indicating a potential mechanism by which it exerts its protective effect against the stress-induced behavioral outcome.

Abstract Background Less than half of all individuals with post-traumatic stress disorder (PTSD) remit spontaneously and a large proportion of those seeking treatment do not respond sufficiently. This suggests that there may be subgroups of individuals who are in need of augmentative or alternative treatments. One of the most frequent pathophysiological findings in PTSD is alterations in the hypothalamic–pituitary–adrenal (HPA) axis, including enhanced negative feedback sensitivity and attenuated peripheral cortisol. Given the role of the HPA axis in cognition, this pattern may contribute to PTSD symptoms and interfere with key processes of standard first-line treatments, such as trauma-focused cognitive behavioural therapy (TF-CBT). Methods This review provides a comprehensive summary of the current state of research regarding the role of HPA axis functioning in PTSD symptoms and treatment. Results Overall, there is preliminary evidence that hypocortisolaemia contributes to symptom manifestation in PTSD; that it predicts non-responses to TF-CBT; and that it is subject to change in parallel with positive treatment trajectories. Moreover, there is evidence that genetic and epigenetic alterations within the genes NR3C1 and FKBP5 are associated with this hypocortisolaemic pattern and that some of these alterations change as symptoms improve over the course of treatment. Conclusions Future research priorities include investigations into the role of the HPA axis in day-to-day symptom variation, the time scale in which biological changes in response to treatment occur, and the effects of sex. Furthermore, before conceiving augmentative or alternative treatments that target the described mechanisms, multilevel studies are warranted.
