AB  - Endocannabinoids act as a stress response system; simultaneously, the modulation of this system has emerged a novel approach for the therapy of cardiovascular disorders. We investigated the protective effects of the chronic administration of the fatty acid amide hydrolase inhibitor URB597 on morphology, pro-inflammatory and anti-inflammatory cytokine, the cytoplasm-nuclear distribution of JAK2/STAT3, and NF-κB and Nrf2/HO-1 signaling in the left ventricle of female and male rats exposed to chronic unpredictable stress. Our results show that URB597 treatment exhibits an antidepressant-like effect, decreases the heart/body weight ratio, prevents the hypertrophy of cardiomyocytes, and reduces the increased level of IL-6 in the wall of the left ventricle of stressed female and male rats. The phosphorylation levels of JAK2 and STAT3 in the ventricle of male rats treated with URB597 were declined, whereas in female rats the decrease of STAT3 was observed. In addition, URB597 reduced increased NF-κB in both females and males and increased the expression of Nrf2 and HO-1 protein in the cytosol of male rats, whereas did not affect their levels in females. Cardioprotective effects of URB597 could be linked to the ability to inhibit the JAK2 in males and the STAT3 inflammatory signaling pathways in both females and males.

AB  - Social stress produces behavioral alterations, and autonomic and cardiac dysfunction in animals. In addition to the well-known roles of oxytocin on birth and maternal bonding, recent evidence shows that this neuropeptide possesses cardio-protective properties. However less is known about its role in the regulation of the autonomic nervous system. The direct influence of oxytocin on the cardiac catecholamine synthesizing enzyme, transport beta-adrenoceptors and muscarinic receptors in animals exposed to chronic social isolation stress has not yet been studied. In this study, we examined the influence of peripheral chronic oxytocin treatment on anxiety-related behavior, the morphology and content of epinephrine and norepinephrine, mRNA and protein levels of tyrosine hydroxylase (TH), norepinephrine transporter (NET) and receptors <beta> 3 (β3-AR) and muscarinic 2 (M2 MR) in the right and left cardiac atrium and ventricle of chronically socially isolated male rats. Our results show that oxytocin treatment exhibits an anxiolytic effect, decreases the heart/body weight ratio and prevents the hypertrophy of cardiomyocytes in the wall of the left ventricle of stressed rats. Epinephrine and TH protein levels were unchanged after prolonged oxytocin treatment. Peripheral oxytocin administration led to the enhancement of gene expression of β3-AR in both atria, NET protein in the left ventricle and gene expression of M2 MR in the right atrium and the left ventricle of chronically socially isolated rats. The study provides evidence that oxytocin treatment in chronically socially isolated animals enhances norepinephrine uptake and expression of cardio-inhibitory receptors in cardiac tissues, which could have a beneficial effect on the cardiovascular system under the increased activity of the sympathoneural system. © 2018 Elsevier Inc.

AB  - Exposure of an organism to chronic psychosocial stress may affect brain-derived neurotrophic factor (BDNF) expression that has been implicated in the etiology of psychiatric disorders, such as depression. Given that depression in humans has been linked with social stress, the chronic social stress paradigms for modeling psychiatric disorders in animals have thus been developed. Chronic social isolation in animal models generally causes changes in hypothalamic-pituitary-adrenal axis functioning, associated with anxiety-and depressive-like behaviors. Also, this chronic stress causes downregulation of BDNF protein and mRNA in the hippocampus, a stress-sensitive brain region closely related to the pathophysiology of depression. In this review, we discuss the current knowledge regarding the structure, function, intracellular signaling, inter-individual differences and epigenetic regulation of BDNF in both physiological conditions and depression and changes in corticosterone levels, as a marker of stress response. Since BDNF levels are age dependent in humans and rodents, this review will also highlight the effects of adolescent and adult chronic social isolation models of both genders on the BDNF expression.

AB  - Purpose/aim: The adreno-medullar system represents one of the main systems involved in the response to stressful events. The neuropeptide oxytocin, is highly sensitive to the social environment, and regulates autonomic function. Adreno-medullary activity is dependent on the synthesis of catecholamine, its reuptake, release, degradation and vesicular transport. A direct influence of oxytocin on catecholamine synthesizing enzyme and transports in animals exposed to chronic social isolation stress has not been studied yet. Materials and methods: In the present study, we examined the effect of chronic oxytocin treatment on the level of plasma catecholamine and its content, mRNA and protein levels of tyrosine hydroxylase (TH), noradrenaline transporter (NET) as well as vesicular monoamine transporter 2 (VMAT2) in the adrenal medulla of socially isolated rats. Results: Our results show that, by the end of 12 weeks, social isolation did not produce any significant changes in catecholamine content but increased plasma catecholamine level and synthesis in the adrenal medulla. Oxytocin treatment had no further effect either on catecholamine synthesis or content in socially stressed animals whereas a significant elevation of plasma norepinephrine and epinephrine were reduced. On the other hand, chronic isolation caused a significant increase in VMAT2 and decrease in NET protein levels. Oxytocin treatment brought about an increase in protein levels of NET and its return to the levels of control group. Besides, it further increases VMAT2 protein levels in the adrenal medulla of individually housed rats. Conclusion: The present results show that peripheral oxytocin treatment enhances catecholamine uptake and storage in the adrenal medulla of chronically isolated animals.

AB  - The hippocampus is a brain structure involved in the regulation of hypothalamic-pituitary-adrenal (HPA) axis and stress response. It plays an important role in the formation of declarative, spatial and contextual memory, as well as in the processing of emotional information. As a part of the limbic system, it is a very susceptible structure towards the effects of various stressors. The molecular mechanisms of structural and functional alternations that occur in the hippocampus under chronic stress imply an increased level of circulating glucocorticoids (GCs), which is an HPA axis response to stress. Certain data show that changes induced by chronic stress may be independent from the GCs levels, opening the possibility of existence of other poorly explored mechanisms and pathways through which stressors act. The hippocampal GABAergic parvalbumin-positive (PV+) interneurons represent an especially vulnerable population of neurons in chronic stress, which may be of key importance in the development of mood disorders. However, cellular and molecular hippocampal changes that arise as a consequence of chronic stress still represent a large and unexplored area. This review discusses the current knowledge about the PV+ interneurons of the hippocampus and the influence of chronic stress on this intriguing population of neurons.

AB  - Social isolation induced a significant increase in resting heart rate and reduction in heart rate variability. Dysfunction of the intrinsic cardiac nervous system is implicated in the genesis of cardiovascular diseases. Previous evidence suggests that cardiac ganglia contain noradrenergic neurons. Thus, immunohistochemical expression of catecholamine-synthesizing enzyme tyrosine hydroxylase (TH) and vesicular monoamine transporter 2 (VMAT2) were analyzed, as well as the effects of social isolation stress on mRNA and protein levels of this enzyme and transporter in the intrinsic cardiac nervous system of adult rats. Our results indicate that cardiac ganglion neurons express TH and VMAT2 immunoreactivity. Chronic isolated stress of rats caused a decrease in TH mRNA and VMAT2 mRNA in the neurons of intrinsic cardiac ganglia. No significant alterations in the protein levels of TH and VMAT2 were observed in these neurons. These data indicate that the neurons of intrinsic cardiac ganglia express TH as well as VMAT2 but that social isolation stress does not change their protein levels.

AB  - Thioacetamide (TAA) is widely used as a model of hepatic encephalopathy (HE). The aim of our study was to investigate the effects of TAA on electroencephalographic (EEG) changes in rats and to compare them with human HE. Male Wistar rats were divided into groups: (1) saline-treated group and (2) TAA-treated groups: TAA(300) (300 mg/kg), TAA(600) (600 mg/kg), and TAA(900) (900 mg/kg). Daily dose of TAA (300 mg/kg) was administered intraperitoneally once (TAA(300)), twice (TAA(600)), or thrice (TAA(900)) in subsequent days. EEG changes were recorded about 24 h after the last dose of TAA. Absolute and relative power density in alpha bands were significantly higher in TAA(300) versus control group. In TAA(300), absolute beta power density was higher and relative beta power density was lower versus control group. Absolute alpha, theta, delta, and relative theta power were significantly lower, while relative power in delta band was significantly higher in TAA(900) versus control group (p LT 0.01). In conclusion, decrease in EEG voltage with an increase in delta relative power, which correspond to the EEG manifestations of severe HE in humans, was observed in TAA(900) group. Electrical activity in TAA(300) group correlates with mild HE in humans.

AB  - In modern medicine implants are very important and so is their design and choice of materials. Almost equally important is the choice of imaging technique used to in vivo monitor their fate and biocompatibility. The aim of this study was to evaluate the ability of magnetic resonance imaging (MRI) in monitoring the biocompatibility of two newly designed carbon fibers. We have analyzed the interaction of surface functionalized carbon fibers (basic and acidic) with muscle and subcutaneous tissues of rabbits. MRI techniques showed to be useful in longitudinal monitoring of the surrounding tissues, assessment of biocompatibility of new implants, and in the distinction of in vivo surgical edema from inflammation. Histopathology confirmed MRI results, thus showing that MRI has a great potential for in vivo studies of such materials.
