Background: A combination therapy with PCSK9-inhibitors (PCSK9-I) and lipoprotein-apheresis (LA) may have synergistic effects on circulating lipid and lipoprotein levels, in particular in Homozygous Familial Hypercholesterolaemic (HoFH) subjects. The relationships between the above mentioned novel therapeutic approaches as highly effective treatment option for Dyslipidemia in Heterozygous Familial Hypercholesterolaemic (HeFH) patients deserve further investigation in larger datasets. Objective: This review aims to present the role of lipoprotein apheresis in the management of familial hypercholesterolaemia and discuss the potential advantages and disadvantages of its combination with PCSK9 inhibitors. Methods: A comprehensive literature search regarding lipoprotein apheresis in patients with familial hypercholesterolaemia and its combination with PCSK9 inhibitors has been performed. Results: LA is also a potent therapeutic player having impact on inflammation and related mediators. A large body of evidence on this is available. On the contrary, only few observations are available on PCSK9-I effects on inflammation. Conclusions: It is quite clear that further investigation on possible direct and/or indirect pleiotropic effects of PCSK9-I on inflammatory molecules is necessary and to be expected. Evidence on both arguments with regard to HoFH and HeFH, are reported in short.

Bone morphogenetic proteins (BMPs) are members of the transforming growth factor-β superfamily of ligands that impact on a multitude of biological processes including cell type specification, differentiation and organogenesis. Furthermore, a large body of evidence points towards important BMP-dependent mechanisms in tumorigenesis. In accordance with their diverse actions, BMPs have been demonstrated to serve as auto-, para- and endocrine modulators also in a number of hormonal systems. In this review, we highlight novel aspects of BMP-dependent regulatory networks that pertain to adrenal physiology and disease, which have been uncovered during recent years. These aspects include the role of BMP-dependent mechanism during adrenal development, modulating effects on catecholamine synthesis and steroidogenesis and dysregulation of BMP signalling in adrenal tumorigenesis. Furthermore, we summarize potential therapeutic approaches that are based on reconstitution of BMP signalling in adrenocortical tumour cells.

Analysis Of Dynamics

The article considers the role of trust in the economy, the mechanisms of its accumulation and the possibility of using it as one of the growth factors in the future. The advantages and disadvantages of measuring the level of generalized trust using two alternative questions — about trusting people in general and trusting strangers — are analyzed. The results of the analysis of dynamics of the level of generalized trust among Russian youth, obtained within the study of the Institute for National Projects in 10 regions of Russia, are presented. It is shown that there are no significant changes in trust in people in general during the study at university. At the same time, the level of trust in strangers falls, which can negatively affect the level of trust in the country as a whole, and as a result have negative effects on the development of the economy in the future. Possible causes of the observed trends and the role of universities are discussed. Also the question about the connection between the level of education and generalized trust in countries with different quality of the institutional environment is raised.

The revelation of adult brain exhibiting neurogenesis has established that the brain possesses great plasticity and that neurons could be spawned in the neurogenic zones where hippocampal adult neurogenesis attributes to learning and memory processes. With strong implications in brain functional homeostasis, aging and cognition, various aspects of adult neurogenesis reveal exuberant mechanistic associations thereby further aiding in facilitating the therapeutic approaches regarding the development of neurodegenerative processes in Alzheimer’s Disease (AD). Impaired neurogenesis has been significantly evident in AD with compromised hippocampal function and cognitive deficits. Melatonin the pineal indolamine augments neurogenesis and has been linked to AD development as its levels are compromised with disease progression. Here, in this review, we discuss and appraise the mechanisms via which melatonin regulates neurogenesis in pathophysiological conditions which would unravel the molecular basis in such conditions and its role in endogenous brain repair. Also, its components as key regulators of neural stem and progenitor cell proliferation and differentiation in the embryonic and adult brain would aid in accentuating the therapeutic implications of this indoleamine in line of prevention and treatment of AD.

Tinnitus is a common otologic symptom and probably the most troublesome. Tinnitus causes a number of physical and psychological consequences, that interfere with the quality of life of the patient. Many authors believe that the presence of tinnitus in children is a matter of lesser importance than in adults because it is met less frequently and would be a fleeting symptom, inoffensive for them (Graham, 1981). In addition, the prevalence of tinnitus during adolescence and even in young adults is increasing, possibly as a consequence of the increased ambient noise (Bulbul SF, Shargorodsky J). Various therapeutic approaches have generated different results, which led us to consider the role of psychological factors, hence the need to underline the particularities of this symptom in childhood.

This study investigates the synergistic effects of ion exchange and biodegradation methods to remove the Acid Blue 193 also called Gryfalan Navy Blue RL (GNB) dye from wastewater. Ion exchange studies were performed using a strongly basic anion exchange resin Amberlite IRA 400. The equilibrium was characterized by a kinetic and thermodynamic points of view, establishing that the sorption of the GNB dye was subject to the Freundlich isotherm model with R2 = 0.8710. Experimental results showed that the activated resin can removed up to 93.4% when the concentration of dye solution is 5.62�10-2 mM. The biodegradation of the GNB was induced by laccase, an enzyme isolated from white-rot fungus. It was also analyzed the role of pH and dye concentration on GNB biodegradation, so 5�10-2 mM dye had a maximum discoloration efficiency of 82.9% at pH of 4. The laccase showed a very fast and robust activity reaching in a few minutes a Km value of 2.2�10-1mM. In addition, increasing the GNB concentration up to 8�10-1 mM did not triggered a substrat inhibition effect on the laccase activity. Overall, in this study we proposed a mixt physicochemical and biological approach to enhance the GNB removal and biodegradability from the wastewaters and subsequently the environment.

Background: Myocardial redox state is a critical determinant of atrial biology, regulating cardiomyocyte apoptosis, ion channel function, and cardiac hypertrophy/fibrosis and function. Nevertheless, it remains unclear whether the targeting of atrial redox state is a rational therapeutic strategy for atrial fibrillation prevention. Objective: To review the role of atrial redox state and anti-oxidant therapies in atrial fibrillation. Method: Published literature in Medline was searched for experimental and clinical evidence linking myocardial redox state with atrial fibrillation pathogenesis as well as studies looking into the role of redoxtargeting therapies in the prevention of atrial fibrillation. Results: Data from animal models have shown that altered myocardial nitroso-redox balance and NADPH oxidases activity are causally involved in the pathogenesis of atrial fibrillation. Similarly experimental animal data supports that increased reactive oxygen / nitrogen species formation in the atrial tissue is associated with altered electrophysiological properties of atrial myocytes and electrical remodeling, favoring atrial fibrillation development. In humans, randomized clinical studies using redox-related therapeutic approaches (e.g. statins or antioxidant agents) have not documented any benefits in the prevention of atrial fibrillation development (mainly post-operative atrial fibrillation risk). Conclusion: Despite strong experimental and translational data supporting the role of atrial redox state in atrial fibrillation pathogenesis, such mechanistic evidence has not been translated to clinical benefits in atrial fibrillation risk in randomized clinical studies using redox-related therapies.
