A Brief Review of the Relationship between Addiction and Memory Systems

World Journal of Neuroscience 2023年第3期13卷 151-159页

作者： kevin patrick barman Drug Studies/Human Services Rio Hondo College Whittier USA

This essay will reexamine research on the relationship between human memory and addiction. This paper will review several studies that discussed how memory systems in the human brain are involved in the acquisition of behavior that is learned and is associated with the development of drug addiction and drug relapse. Additional information reveals that when individuals make the transition from recreational drug or impulsive use to compulsive drug abuse, which may result in a neuroanatomical change in areas of the brain from cognitive control guided by the hippocampus/dorsomedial striatum towards conditioned control of behavior managed by the dorsolateral striatum (DLS) [1]. This review also looked at studies that involved experiments with humans and lower animals, which suggested that the hippocampus mediates a cognitive/spatial type of memory, while the dorsal striatum manages stimulus-response (S-R) habit memory, and the amygdala governs the classical conditioning form of learning and stimulus-affective-associative relationships [1]. Overall, these studies utilize the hypothesis of the memory systems view of addiction, and the involvement of learning and memory in the context of drug addiction, which was proposed by them [2]. This theory has been proposed in response to drug addiction research and includes alcohol, amphetamine, and cocaine [1]. The research also explains how stress and anxiety can play a role in how strong emotional excitement can lead to dependent habit memory in rodents and humans [1]. .

Biochemical Changes in the Brain and Metabolism as Risk Factors of Neurological Disorders

引用

World Journal of Neuroscience 2022年第2期12卷 45-56页

作者： kevin patrick barman SAERA (School of Advanced Education Research and Accreditation and Education) Castellon de la Plana Spain

This paper aims to examine theories that attempt to explain biochemical changes in the brain as well as the metabolism of individuals who experience symptoms and conditions related to neurological disorders like depression. A systematic literature search was performed on NCBI and PubMed. The search included the keywords neurological disorders, monoamine hypothesis, metabolic syndrome, oxytocin receptor, dietary health, and magnesium intake. Twenty-five research articles met the criteria for the literature review of this examination. In particular, this paper will review multiple studies that investigate the monoamine (MAO) hypothesis of depression and metabolic syndrome (MetS) as a risk factor for neurological disorders. While studies that evaluate additional risk factors for neurological disorders, such as autoimmunity and rheumatic diseases, oxytocin receptor (OXTR) DNA methylation in postpartum depression, dietary health in children and their psychological health, and dietary magnesium and cardiovascular disease, will be reviewed as well.

Combination Activity of Standard Antituberculosis Drugs and Extracts of Medicinal Plants Commonly Used in Traditional Treatment of Tuberculosis in Uganda

引用

Advances in Infectious Diseases 2024年第3期14卷 511-522页

作者： Moses Mpeirwe kevin Komakech Duncan Ssesazi patrick Engeu Ogwang Joel Bazira Department of Microbiology Mbarara University of Science and Technology Mbarara Uganda Department of Medical Microbiology Mycobacteriology (BSL-3) Laboratory Makerere University Kampala Uganda Department of Pharmaceutical Sciences Mbarara University of Science and Technology Mbarara Uganda Department of Pharmacy Mbarara University of Science and Technology Mbarara Uganda

Introduction: Resistance to antituberculosis drugs and adverse drug reactions remain the leading causes of tuberculosis therapeutic failure globally. Despite the increasing acceptance of medicinal plant use in combination with conventional antituberculosis drugs in treatment of tuberculosis (TB) in Uganda, there is paucity of knowledge on their combination effect. Aim: This research aimed to determine combination activity of standard antituberculosis drugs with extracts of Zanthoxylum leprieurii Guill. & Perr. and Rubia cordifolia L., the two common antituberculosis medicinal plants in Uganda, against pansensitive (H37Rv) and multi-drug resistant (MDR) Mycobacterium tuberculosis strains. Materials and Methods: Two reference MTB strains (H37Rv and MDR strain) were inoculated on Middlebrook 7H11 medium containing a combination of standard antituberculosis drugs and methanol extracts of Z. leprieurii and R. cordifolia at varying concentrations. The number of colonies on the plates was observed and counted weekly for up to 8 weeks. In vitro combination activity was determined using proportion method. Mean percentage inhibition was calculated for the reduction of number of colonies on drug-extract combination medium in relation to drug-extract-free control medium. Results: Drug-extract combinations showed good combination activity against Mycobacterium tuberculosis strains when compared with individual standard anti-TB drugs. This was more exhibited against MDR strain. There was however a reduction in percentage inhibition when extracts were combined with ethambutol and streptomycin against H37Rv strain. Conclusions: Zanthoxylum leprieurii and Rubia cordifolia in combination with standard anti-TB drugs exhibited increased in vitro activity against Mycobacterium tuberculosis, especially MDR-TB strain. This justifies the local use of these plants in traditional treatment of tuberculosis especially in resistant cases in Uganda.
