Abstract (sommario):

Neurotransmitters are chemical messengers that play an important role in the nervous system’s control of the body’s physiological state and behaviour. Abnormal levels of neurotransmitters are closely associated with some mental disorders. Therefore, accurate analysis of neurotransmitters is of great clinical importance. Electrochemical sensors have shown bright application prospects in the detection of neurotransmitters. In recent years, MXene has been increasingly used to prepare electrode materials for fabricating electrochemical neurotransmitter sensors due to its excellent physicochemical

Abstract (sommario):

Neurotransmitters are chemical compounds released by nerve cells, including neurons, astrocytes, and oligodendrocytes, that play an essential role in the transmission of signals in living organisms, particularly in the central nervous system, and they also perform roles in realizing the function and maintaining the state of each organ in the body. The dysregulation of neurotransmitters can cause neurological disorders. This highlights the significance of precise neurotransmitter monitoring to allow early diagnosis and treatment.

In the CNS, minor changes in the concentration of neurotransmitters such as glutamate or dopamine can lead to neurodegenerative diseases. We present an evolutionary perspective on the function of neurotransmitter toxicity in the CNS. We hypothesize that neurotransmitters are selected because of their toxicity, which serves as a test of neuron quality and facilitates the selection of neuronal pathways. This perspective may offer additional explanations for the reduction of neurotransmitter concentration in the CNS with age, and suggest an additional role for the blood-brain barrier. It may also

Abstract (sommario):

Neuronal transmission relies on electrical signals and the transfer of chemical signals from one neuron to another. Chemical messages are transmitted from presynaptic neurons to neighboring neurons through the triggered fusion of neurotransmitter-filled vesicles with the cell plasma membrane. This process, known as exocytosis, involves the rapid release of neurotransmitter solutions that are detected with high affinity by the postsynaptic neuron. The type and number of neurotransmitters released and the frequency of vesicular events govern brain functions such as cognition, decision making, le

Abstract (sommario):

Introduction. Z-drugs are a group of “non-benzodiazepine” drugs with the main mode of action regulating sleep behavior in humans through exposure to GABA receptors. There are reports indicating the toxic effects of overdose and abuse of zaleplon. However, information on the effect of Z-drugs on neurotransmitter levels is scarce.  The aim of this study was to study the effect of zaleplon exposure on neurotransmitter levels in the larvae of Danio fish using targeted metabolomics.  Material and methods. 4-hour exposure to zaleplon in concentrations of 0.1, 1.0, 10, 100 and 1000 μg/l w

Abstract (sommario):

The Neurotransmitters are referred as the molecules of the chemical messengers in the body. Their job is to transmit signals from nerve cells to target cells. These target cells may be in muscles, glands, or other nerves. The nervous system controls the body’s organs, psychological and physical functions and play important roles in the system. In Ayurveda the vata dosha the controller of the body and is the causation for all the movements in the body. The dosha classifies in to 5 types are prana vata, udana vata, samana vata, vyana vata, apana vata. All these are helping all kind of movements

Abstract (sommario):

Molecular in vivo neuroimaging techniques can be used to measure regional changes in endogenous neurotransmitters, evoked by challenges that alter synaptic neurotransmitter concentration. This technique has most successfully been applied to the study of endogenous dopamine release using positron emission tomography, but has not yet been adequately extended to other neurotransmitter systems. This review focuses on how the technique has been applied to the study of the 5-hydroxytryptamine (5-HT) system. The principles behind visualising fluctuations in neurotransmitters are introduced, with refe

Abstract (sommario):

Classical neurotransmitters such as acetylcholine (ACh), biogenic amines and ϒ-aminobutyric acid (GABA) have been shown to mediate various forms of intercellular signalling in marine invertebrates including sea urchin larvae (Buznikov et al., 1996). The presence of amines and GABA in the nervous system of sea urchin larvae has been demonstrated by a cytochemical method at the gastrula stage (Bisgrove & Burke, 1987). However, few quantitative analyses of neurotransmitters have been attempted in the embryonic sea urchin. To accomplish this during the period of embryogenesis, in the present s

Abstract (sommario):

Alzheimer’s disease (AD) is the most frequent cause of cognitive impairment in middle-aged and older populations. There is a lack of drugs that demonstrate significant efficacy in AD, so the study of the pathogenesis of AD is of great importance. More efficacious interventions are needed, as reflected by our population’s fast aging. Synaptic plasticity is the capacity of neurons to adjust their connections, and it is strongly tied to learning and memory, cognitive function, and brain injury recovery. Changes in synaptic strength, such as long-term potentiation (LTP) or inhibition (LTD), are th

Abstract (sommario):

Carbon-based electrodes have been developed for the detection of neurotransmitters over the past 30 years using voltammetry and amperometry. The traditional electrode for neurotransmitter detection is the carbon fiber microelectrode (CFME). The carbon-based electrode is suitable for in vivo neurotransmitter detection due to the fact that it is biocompatible and relatively small in surface area. The advent of nanoscale electrodes is in high demand due to smaller surface areas required to target specific brain regions that are also minimally invasive and cause relatively low tissue damage when i

Abstract (sommario):

The aim of this work is to introduce a computer science solution to manage emotions and affections and connect them to the causes as in humans. The scientific foundation of this work lies in the ability to model the affective and emotional states of an individual or artificial intelligence (AI). Then, in this study, we go a step further by exploring how to extend this capability by linking it to the underlying causes—specifically, by establishing a connection between emotions, affective states, and neurotransmitter activities. The methods used in this study pertain to decision support systems

Abstract (sommario):

Migraine onset is associated with the abnormal release of vasoactive neurotransmitters from perivascular nerves, and these neurotransmitters are involved in the pathophysiology of migraine. Hyperalgesia is a key feature of migraine, and accumulating evidence indicates that electroacupuncture (EA) at the single acupuncture point (Fengchi [GB20]) is effective in ameliorating hyperalgesia. In clinical practice, multiple acupuncture points are widely used, especially GB20 and Yanglingquan (GB34). However, the role played by vasoactive neurotransmitters in acupuncture antihyperalgesic effect at the

Abstract (sommario):

Neurotransmitters as electrochemical signaling molecules are essential for proper brain function and their dysfunction is involved in several mental disorders. Therefore, the accurate detection and monitoring of these substances are crucial in brain studies. Neurotransmitters are present in the nervous system at very low concentrations, and they mixed with many other biochemical molecules and minerals, thus making their selective detection and measurement difficult. Although numerous techniques to do so have been proposed in the literature, neurotransmitter monitoring in the brain is still a c

Abstract. Neurotransmitters play a crucial role in the production and treatment of psychiatric disorders. A neurotransmitter is a chemical that transmits signals and is very closely associated with a variety of neural activities such as mood, memory, growth and development, and drug addiction. In recent years, significant progress has been made in the research on psychiatric diseases caused by uneven neurotransmitter secretion and drug treatment for psychiatric disorders. By studying the way drugs act on different neurotransmitters and their receptors, regulate the functional activities of the
