Unraveling Bioactive Constituents Isolated from Knema hookeriana Warb. as Potential Acetylcholinesterase Inhibitorsby
![]() ![]() ![]() ![]() ![]() ![]() Abstract
The Myristicaceae family, particularly the Knema genus, is renowned for its diverse bioactive compounds, including lignans, flavonoids, and phenolics. This study explores the phytochemical profile of Knema hookeriana Warb. leaves and evaluates their potential as acetylcholinesterase (AChE) inhibitors. Phytochemical extraction was performed using a cold maceration method with a polarity-gradient solvent system (hexane, ethyl acetate, and methanol). The isolated compounds were purified through chromatographic techniq [...] 31 236 |
Mental Health Disorders Following Exposure to Endocrine Disruptor ChemicalsAbstract
There is growing scientific concern regarding how endocrine-disrupting chemicals (EDCs) impact central nervous system (CNS) disorders. Both anecdotal and preclinical studies suggest a link between EDC exposure and major depressive disorder (MDD), potentially leading to neurodegenerative outcomes. EDCs primarily exhibit their biological effects by interacting with hormone receptors. Nonetheless, there is scientific evidence pointing to dysfunction in the hypothalamic-pituitary-gonadal-adrenal axis, which is linked t [...] 52 443 |
Neurotoxicity Following Exposure to ChlorpyrifosAbstract
Neurotoxicity occurs when exposure to a biological, chemical, or physical agent, especially a neurotoxin, alters the normal activity of the nervous system in a way that results in permanent or reversible damage to neurons and nerve tissue and disrupts the functioning of the brain and nervous system. Chlorpyrifos is a broad-spectrum organophosphorus insecticide that has been used worldwide for more than 50 years and can damage the nervous system of insects by creating neurotoxicity. Epidemiological studies show that [...] 48 458 |
Unraveling the Involvement of Serotonergic 5-Hydroxytryptamine Receptor-6 Activation in Chronic Pain: A Narrative Reviewby
![]() ![]() ![]() ![]() ![]() Abstract
Chronic pain is a significant and global healthcare issue that hugely implies the quality of life and productivity of the affected individuals. It is challenging to treat and thus necessitates a deeper understanding of its underlying pathomechanisms to develop targeted interventions. Serotonin is one of the essential neurotransmitters involved in the propagation of pain signals through both ascending and descending pathways, acting via various receptor subtypes, including the 5-hydroxytryptamine receptor-6 (5-HT6R) [...] 57 518 |
Pregnancy Risk Factors in Cerebrovascular DiseaseAbstract
Cerebrovascular diseases such as strokes and cerebral hemorrhages are important causes of death in the world, which increase during pregnancy due to physiological conditions. This study investigated risk factors such as diabetes mellitus, hypertension and other factors by searching in databases. After searching, 35 articles were reviewed based on the inclusion criteria. The inclusion criteria included articles from 2014-2024 related to the words "pregnancy" AND "cerebrovascular disease." The obtained results were e [...] 59 573 |
Forgiveness Therapy to Reduce Violent Behavior in Individuals with Schizophrenia: A Case StudyAbstract
This study aims to describe the application of forgiveness therapy as a psychosocial intervention for a schizophrenia patient with violent behavior. Mr. M, a 19-year-old male diagnosed with schizophrenia, exhibited psychotic symptoms, including auditory hallucinations, persecutory delusions, agitation, and aggression. He had a history of trauma due to physical violence from his brother. The patient was diagnosed with a risk for violence toward others. Forgiveness therapy was implemented over six sessions, each last [...] 91 754 |
Do We Care about Preschool Children's Leisure Time? Correlations between Anxiety Symptoms and Leisure Time Allocation. Results of a Cross-Sectional StudyAbstract
Children's leisure time in the Western world is changing compared to what it used to be in the previous decades. Children's involvement in organized activities and screen time use is increasing, while outdoor play, despite once being the main leisure time activity for children, is declining. Gray, Oliver and other contemporary theorists link this shift in children's lifestyles to an increase in the prevalence of anxiety disorders. This study aimed to determine whether allocating preschool children's leisure time (s [...] 144 1442 |
Functional Prognosis of Spinal Cord Injury Due to Spinal TuberculosisAbstract
Spinal tuberculosis (TB), an extrapulmonary manifestation of TB, primarily involves one or multiple vertebrae, with a high prevalence at the thoracolumbar region, which can compromise spinal cord integrity and result in severe sequelae such as paraplegia, bladder and bowel dysfunction, and mobility limitation. This study aimed to review medical, surgical, and rehabilitation management, clinical outcomes, and prognostic factors of spinal TB with spinal cord injury (SCI). Research was conducted utilizing databases su [...] 77 804 |
The Independence Principle - A Neglected Feature of the Hodgkin Huxley Legacyby
![]() ![]() Abstract
The legacy of Hodgkin and Huxley rests on their squid giant axon studies, which were summarised in an empirical model of impressive predictive power that successfully quantified the permeability changes of excitable membranes and accurately reconstructed the action potential. Hodgkin and Huxley applied the independence principle to their experimental data in order to reveal potential mechanism(s) of trans-membrane ion movements. This was motivated by their lack of information on the manner in which ions crossed the [...] 81 635 |
Neurotoxicity Following Exposure to Micro and Nanoplasticsby
![]() ![]() Abstract
The pervasive presence and enduring existence of micro and nanoplastics in the environment render their exposure to humans and aquatic creatures unavoidable. Research indicates these tiny plastic particles can be taken in by aquatic beings and mammals. Once within the body, micro and nanoplastics have the capability to infiltrate the brain, although the level of penetration and the subsequent neurotoxic effects are not fully explored. Previous studies indicate that metal (oxide) nanoparticles can enter the brain an [...] 180 1857 |
