Charles D. Nichols
Charles D. Nichols is an American people, American pharmacologist who studies psychedelic drugs and inflammation. He also studied Drosophila melanogaster, fruit flies for many years, including giving them psychedelics. Nichols is the son of famous psychedelic chemist David E. Nichols. Charles Nichols is a professor and researcher at Louisiana State University School of Medicine and the lead scientist of the psychedelic medicine pharmaceutical company Eleusis Therapeutics (since acquired by Beckley Foundation, Beckley Psytech). He is also the co-editor-in-chief of the academic journal ''Psychedelic Medicine'', which started in 2022. Nichols discovered that psychedelics such as DOI (drug), DOI show powerful anti-inflammatory effects and that this effect is mediated by functional selectivity, functionally selective activation of serotonin 5-HT2A receptor, 5-HT2A receptors. Moreover, he found that the anti-inflammatory effects of psychedelics are dissociable from their hallucinogenic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Bachelor's Degree
A bachelor's degree (from Medieval Latin ''baccalaureus'') or baccalaureate (from Modern Latin ''baccalaureatus'') is an undergraduate degree awarded by colleges and universities upon completion of a course of study lasting three to six years (depending on the institution and academic discipline). The two most common bachelor's degrees are the Bachelor of Arts (BA) and the Bachelor of Science (BS or BSc). In some institutions and educational systems, certain bachelor's degrees can only be taken as graduate or postgraduate educations after a first degree has been completed, although more commonly the successful completion of a bachelor's degree is a prerequisite for further courses such as a master's or a doctorate. In countries with qualifications frameworks, bachelor's degrees are normally one of the major levels in the framework (sometimes two levels where non-honours and honours bachelor's degrees are considered separately). However, some qualifications titled bachelor's ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Psychedelic Microdosing
Psychedelic microdosing is a form of microdosing, drug microdosing in which sub-hallucinogenic doses of serotonergic psychedelics like LSD and psilocybin are taken for claimed cognitive and emotional benefits. Uses, research, and effects A variety of perceived benefits of psychedelic microdosing have been anecdotal evidence, anecdotally claimed, such as beneficial effects on mood (psychology), mood or well-being, anxiety, cognitive function, creativity, and productivity. In addition, people informally use microdosing to treat psychiatric conditions and it is being formally clinically studied for such purposes. Examples include for depression (mood), depression, anxiety, obsessive–compulsive disorder (OCD), post-traumatic stress disorder (PTSD), substance misuse, and schizophrenia, among others. There is very little scientific research on microdosing or its effects as of 2024 however and the claimed beneficial effects of microdosing have largely not been scientifically validated ...

Neuroinflammation
Neuroinflammation is inflammation of the nervous tissue. It may be initiated in response to a variety of cues, including infection, traumatic brain injury,Ebert SE, Jensen P, Ozenne B, Armand S, Svarer C, Stenbaek DS ''et al.'' Molecular imaging of neuroinflammation in patients after mild traumatic brain injury: a longitudinal 123 I-CLINDE SPECT study. ''Eur J Neurol'' 2019. doi:10.1111/ene.13971. toxic metabolites, or autoimmunity. In the central nervous system (CNS), including the brain and spinal cord, microglia are the resident innate immune cells that are activated in response to these cues. The CNS is typically an immunologically privileged site because peripheral immune cells are generally blocked by the blood–brain barrier (BBB), a specialized structure composed of astrocytes and endothelial cells. However, circulating peripheral immune cells may surpass a compromised BBB and encounter neurons and glial cells expressing major histocompatibility complex molecules, perpetuati ...

Asthma
Asthma is a common long-term inflammatory disease of the airways of the lungs. It is characterized by variable and recurring symptoms, reversible airflow obstruction, and easily triggered bronchospasms. Symptoms include episodes of wheezing, coughing, chest tightness, and shortness of breath. A sudden worsening of asthma symptoms sometimes called an 'asthma attack' or an 'asthma exacerbation' can occur when allergens, pollen, dust, or other particles, are inhaled into the lungs, causing the bronchioles to constrict and produce mucus, which then restricts oxygen flow to the alveoli. These may occur a few times a day or a few times per week. Depending on the person, asthma symptoms may become worse at night or with exercise. Asthma is thought to be caused by a combination of genetic and environmental factors. Environmental factors include exposure to air pollution and allergens. Other potential triggers include medications such as aspirin and beta blockers. Diag ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Inflammatory Disease
Inflammation (from ) is part of the biological response of body tissues to harmful stimuli, such as pathogens, damaged cells, or Irritation, irritants. The five cardinal signs are heat, pain, redness, swelling, and Functio laesa, loss of function (Latin ''calor'', ''dolor'', ''rubor'', ''tumor'', and ''functio laesa''). Inflammation is a generic response, and therefore is considered a mechanism of innate immune system, innate immunity, whereas adaptive immune system, adaptive immunity is specific to each pathogen. Inflammation is a protective response involving immune cells, blood vessels, and molecular mediators. The function of inflammation is to eliminate the initial cause of cell injury, clear out damaged cells and tissues, and initiate tissue repair. Too little inflammation could lead to progressive tissue destruction by the harmful stimulus (e.g. bacteria) and compromise the survival of the organism. However inflammation can also have negative effects. Too much inflammat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hallucinogen
Hallucinogens, also known as psychedelics, entheogens, or historically as psychotomimetics, are a large and diverse class of psychoactive drugs that can produce altered states of consciousness characterized by major alterations in thought, mood, and perception as well as other changes. Hallucinogens are often categorized as either being psychedelics, dissociatives, or deliriants, but not all hallucinogens fall into these three classes. Examples of hallucinogens include psychedelics or serotonin 5-HT2A receptor agonists like LSD, psilocybin, mescaline, and DMT; dissociatives or NMDA receptor antagonists like ketamine, PCP, DXM, and nitrous oxide; deliriants or antimuscarinics like scopolamine and diphenhydramine; cannabinoids or cannabinoid CB1 receptor agonists like THC, nabilone, and JWH-018; κ-opioid receptor agonists like salvinorin A and pentazocine; GABAA receptor agonists like muscimol and gaboxadol; and oneirogens like ibogaine and harmaline, a ...

5-HT2A Receptor
The 5-HT2A receptor is a subtype of the 5-HT2 receptor, 5-HT2 receptor that belongs to the serotonin receptor family and functions as a GPCR, G protein-coupled receptor (GPCR). It is a cell surface receptor that activates multiple intracellular signalling cascades. Like all 5-HT2 receptors, the 5-HT2A receptor is coupled to the Gq protein, Gq/G11 signaling pathway. It is the primary excitatory receptor subtype among the serotonin-responsive GPCRs. The 5-HT2A receptor was initially noted for its central role as the primary target of serotonergic psychedelic drugs such as LSD and psilocybin mushrooms. It later regained research prominence when found to mediate, at least in part, the effects of many antipsychotic drugs, particularly atypical antipsychotic, atypical antipsychotics. Downregulation of post-synaptic 5-HT2A receptors is an adaptive response triggered by chronic administration of selective serotonin reuptake inhibitors (SSRIs) and atypical antipsychotics. Elevated 5-HT2A ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Serotonin
Serotonin (), also known as 5-hydroxytryptamine (5-HT), is a monoamine neurotransmitter with a wide range of functions in both the central nervous system (CNS) and also peripheral tissues. It is involved in mood, cognition, reward, learning, memory, and physiological processes such as vomiting and vasoconstriction. In the CNS, serotonin regulates mood, appetite, and sleep. Most of the body's serotonin—about 90%—is synthesized in the gastrointestinal tract by enterochromaffin cells, where it regulates intestinal movements. It is also produced in smaller amounts in the brainstem's raphe nuclei, the skin's Merkel cells, pulmonary neuroendocrine cells, and taste receptor cells of the tongue. Once secreted, serotonin is taken up by platelets in the blood, which release it during clotting to promote vasoconstriction and platelet aggregation. Around 8% of the body's serotonin is stored in platelets, and 1–2% is found in the CNS. Serotonin acts as both a vasoconstrictor and vas ...

Functional Selectivity
Functional selectivity (or agonist trafficking, biased agonism, biased signaling, ligand bias, and differential engagement) is the ligand-dependent selectivity for certain signal transduction pathways relative to a reference ligand (often the endogenous hormone or peptide) at the same receptor. Functional selectivity can be present when a receptor has several possible signal transduction pathways. To which degree each pathway is activated thus depends on which ligand binds to the receptor. Functional selectivity, or biased signaling, is most extensively characterized at G protein coupled receptors (GPCRs). A number of biased agonists, such as those at muscarinic M2 receptors tested as analgesics or antiproliferative drugs, or those at opioid receptors that mediate pain, show potential at various receptor families to increase beneficial properties while reducing side effects. For example, pre-clinical studies with G protein biased agonists at the μ-opioid receptor show equivalent ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Anti-inflammatory
Anti-inflammatory is the property of a substance or treatment that reduces inflammation, fever or swelling. Anti-inflammatory drugs, also called anti-inflammatories, make up about half of analgesics. These drugs reduce pain by inhibiting mechanisms of inflammation, as opposed to opioids, which affect the central nervous system to block pain. Common anti-inflammatory drugs include nonsteroidal anti-inflammatory drugs (NSAIDs), corticosteroids, antileukotrienes, and monoclonal antibodies. Drugs Clinically approved Nonsteroidal anti-inflammatory drugs NSAIDs alleviate pain by counteracting the cyclooxygenase (COX) enzyme involved in pain mechanisms. Some common examples of NSAIDs are aspirin, ibuprofen, and naproxen. Selective COX-2 inhibitors, such as celecoxib, block the enzymatic conversion of arachidonic acid into prostaglandin, inhibiting inflammation and pain. Analgesics commonly associated with anti-inflammatory drugs, such as acetaminophen (paracetamol), hav ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
