Opis:
Addiction to drugs is one of the significant problems in many countries. Opium is a kind of drug that its use goes back to many years ago. Dopamine and serotonin are neurotransmitters involved in the process of addiction. As a result, this study aimed to investigate the blood levels of serotonin, dopamine and physical fitness factors in active and inactive men addicted to opium during their rehabilitation period. This study is a descriptive and Causal after the occurrence. A total of 34 men addicted to opium referring to rehabilitation center had been admitted voluntarily as samples were available in the study. According to a questionnaire answered by them, 16 of them did exercise during their rehabilitation period (active group) and 18 of them did not do any physical activity during this period (inactive group). 5 cc of peripheral blood samples were obtained from both groups and were tested their aerobic capacity, muscular endurance, flexibility, body composition, blood pressure and heart rate. Statistical analysis showed that blood levels of serotonin and dopamine in active group were significantly more than inactive group (p<0.05). In addition, the active group compared with the inactive group had low body fat percent, more muscular endurance, more flexibility, and low resting heart rate (p<0.05). According to the findings, we can conclude that low physical activity but as regular walking can affect blood levels of serotonin and dopamine, and health-related fitness factors of addicted men and as a non-drug treatment is helpful.

Opis:
In the paper, the development and performance of an optical sensor for detection of neurotransmitters (dopamine) is presented. The concentration of dopamine is measured basing on fluorescence quenching of graphene quantum dots. In the sensor, the dopamine molecules coat the graphene quantum dots surface – in result, the quenching of fluorescence occurs due to the Förster resonance energy transfer. The changes in fluorescence correspond to specific concentrations of the neurotransmitter in tested samples, so it is possible to accurately determine the concentration of dopamine in the sample.

Opis:
Deuterium kinetic isotope effects (KIE’s) in the reaction of oxidation of dopamine (DA) catalyzed by the enzyme horseradish peroxidase (HRP, EC 1.11.1.7) was determined using a non-competitive spectrophotometric method. For kinetic studies, the deuterium ring labelled isotopomer [2’,5’,6’-2H3]-dopamine was synthesized using acid catalyzed isotopic exchange between authentic dopamine and heavy water. Deuterium solvent isotope effects (SIE’s) for dopamine and norepinephrine were determined separately for the enzymatic oxidation carried out in the presence or absence of hydrogen peroxide. Some mechanistic details of enzymatic oxidation of dopamine and norepinephrine to corresponding catecholchromes catalyzed by HRP were discussed.

Opis:
The G protein-coupled receptors (GPCRs), one of the largest protein families, are essential components of the most commonly used signal-transduction systems in cells. These receptors, often using common pathways, may cooperate in the regulation of signal transmission to the cell nucleus. Recent scientific interests increasingly focus on the cooperation between these receptors, particularly in a context of their oligomerization, e.g. the formation of dimers that are able to change characteristic signaling of each receptor. Numerous studies on kinin and dopamine receptors which belong to this family of receptors have shown new facts demonstrating their direct interactions with other GPCRs. In this review, current knowledge on signaling pathways and oligomerization of these receptors has been summarized. Owing to the fact that kinin and dopamine receptors are widely expressed in cell membranes where they act as mediators of numerous common physiological processes, the information presented here sheds new light on a putative crosstalk of these receptors and provides more comprehensive understanding of possible direct interactions that may change their functions. The determination of such interactions may be useful for the development of new targeted therapeutic strategies against many disorders in which kinin and dopamine receptors are involved.

Opis:
Introduction. Substance abuse significantly influences human health and may induce problems with social functioning worldwide. Numerous genetic and environmental risk factors, as well as their interactions, accelerate the development of drug addiction. Etiologically, the dopaminergic mesocorticolimbic reward pathways are related to psychoactive substance addiction, and the reward properties of heroin are connected with changes in the mesolimbic dopaminergic system. Objective. The aim of this study is a haplotypic analysis of subjects addicted to polysubstance. However, with the knowledge that this is not a homogenous subgroup, it was decided to separate and analyze homogenous subgroups of subjects in order to find specific haplotypic variants among them. The subjects in the subgroups were addicted to heroin, and subjects with more than two relapses in the past two years. Materials and method. The study group comprised of 301 polysubstance addicted rural male subjects. From this group, 2 homogenous subgroups of subjects were isolated and additionally analyzed: (1) a group of heroin addicted subjects (n=61), and (2) a group of heroin-addicted subjects with at least two relapses in the last two years (n=21). The group consisting of all polysubstance addicted rural subjects and both homogenous subgroups were analyzed against a control group of non-addicted subjects (n=300), matching gender and age. Five polymorphisms in the DRD2/ANKK1 region were analyzed: rs1076560, rs1800498, rs1079597, rs6276 in the DRD2 gene, and rs1800497 in the ANKK1 gene. Results. A statistically significant haplotype association was found in analysis of the heroin addicted subjects, compared to controls, and two possible trends – when comparing the whole group of addicted subjects to controls, and in relapse subgroups, compared to the controls. Conclusion. The results obtained showed that haplotypes indicate a part of the biological component of addiction.

Opis:
Leukocyte adhesion to the vascular endothelium contributes to many immunological and inflammatory disorders. These processes have been shown to be mediated by bradykinin receptor type 2 (B2R) and dopamine receptor type 2 (D2R). In a previous study, we reported the formation of a B2R-D2R heterodimer, possibly altering cellular functions. Hence, in the present study, we examined the effect of co-activation of endothelial cells with B2R and D2R agonists on the interaction of these cells with neutrophils. Bradykinin, the main B2R agonist, significantly increased cell adhesion, and this effect was reversed when the endothelial cells were additionally co-treated with a selective D2R agonist, sumanirole. These results were dependent on the incubation time, showing an opposite tendency after prolonged stimulation. Significant changes in the expression of adhesion proteins, such as E-selectin and intercellular adhesion molecule 1 in endothelial cells were observed. Additionally, the cells preincubated with tumor necrosis factor-α showed decreased cell adhesion and IL-8 release after long incubation with both agonists. The modulation of cell adhesion by D2R and B2R seem to be mediated via STAT3 phosphorylation. In summary, this study demonstrated a protective role of D2R in neutrophil-endothelial cell adhesion induced by bradykinin, especially in cytokine-stimulated endothelial cells.

Opis:
Many recent studies have applied to spike neural networks with spike-timing-dependent plasticity (STDP) to machine learning problems. The learning abilities of dopaminemodulated STDP (DA-STDP) for reward-related synaptic plasticity have also been gathering attention. Following these studies, we hypothesize that a network structure combining self-organized STDP and reward-related DA-STDP can solve the machine learning problem of pattern classification. Therefore, we studied the ability of a network in which recurrent spiking neural networks are combined with STDP for non-supervised learning, with an output layer joined by DA-STDP for supervised learning, to perform pattern classification. We confirmed that this network could perform pattern classification using the STDP effect for emphasizing features of the input spike pattern and DA-STDP supervised learning. Therefore, our proposed spiking neural network may prove to be a useful approach for machine learning problems.

Opis:
Progress in elucidating neuroimmune connections has created new opportunities for improving the treatment of Parkinson’s disease (PD). In recent years, mind-body therapies have been shown to have positive effects on the immune and nervous systems, but interactions at the molecular level have not been tested. Thus, the main aim of the present study was to investigate the effects of therapy based on visualization and suggestion on the concentrations of IL-6, CRP, DA, BDNF, CoQ10, and TAC in patients with advanced PD. Eight patients with PD and 8 elderly healthy men (control group) were enrolled in the study. The therapy lasted 19 days and consisted of three parts: individual sessions with the therapist, mixed (therapist and audio-file), and self-training (audio-file). Blood samples were taken before training and at the end of each part. The expected changes in the investigated markers was observed during therapy: the serum concentration of IL-6 and CRP decreased, whereas DA and BDNF increased, however, this change was observed only after the first part of intervention when the therapy was conducted by the therapist. In the subsequent stages, the levels returned to the baseline. Noteworthy, after the therapy, we observed a significant increase in the motor and intellectual skills of the PD patients. No such changes were observed in the control group. Mind-body therapy based on visualization and suggestions aimed at changing the concentrations of signaling molecules, which are crucial in the development or treatment of PD, may be an effective element in supporting pharmacological therapy.
