t.e new independent.solut.ons of t.e nonlinear different.al equat.on wit. t.me-dependent.coefficient. (NDE-t.) are discussed, for t.e first.t.me, by employing experiment.l device called a drinking bird whose simple back-and-fort. mot.on develops int. wat.r drinking mot.on. t.e solut.on t. a drinking bird equat.on of mot.on manifest. it.elf t.e t.ansit.on from t.ermodynamic equilibrium t. nonequilibrium irreversible st.t.s. t.e independent.solut.on signifying a nonequilibrium t.ermal st.t. seems t. be const.uct.d as if t.o independent.bifurcat.on solut.ons are synt.esized, and so, t.e solut.on is t.nt.t.vely t.rmed as t.e bifurcat.on-int.grat.on solut.on. t.e bifurcat.on-int.grat.on solut.on expresses t.e t.ansit.on from mechanical and t.ermodynamic equilibrium t. a nonequilibrium irreversible st.t., which is explicit.y shown by t.e nonlinear different.al equat.on wit. t.me-dependent.coefficient.

Cannabis sat.va L. is used as fiber, food, and medicine in several count.ies. t.ough it.is illegal for recreat.onal use in most.of t.e world, t.ere are some count.ies t.at.have legalized product.on and sale. t.ere is a lot.of research on product.on of cannabis, but.less so on st.rage t.chnologies. Cannabis cont.ins several high value compounds, such as cannabinoids and t.rpenoids, t.at.are suscept.ble t. degradat.on via light. t.mperat.re, and oxygen. Several st.dies have explored t.mperat.re and light. and indust.y has adjust.d accordingly. However, less is known about.oxygen-induced degradat.on. Biochemical st.dies have demonst.at.d oxidat.ve degradat.on of high value compounds, and many producers use some form of modified at.ospheric packaging (MAP) for st.rage. However, t.e efficacy of MAP is unclear. t.e object.ve of t.is paper is t. review our current.underst.nding of MAP in post.arvest.cannabis st.rage and ident.fy avenues where addit.onal research is needed.

t.e Impact.of Opioid Drugs on Memory and Ot.er Cognit.ve Funct.ons: A Review

引用

Journal of Biosciences and Medicines 2024年第4期12卷 264-287页

作者： Mason t. Bennet. Yuliya Modna Dev Kumar Shah School of Biomedical Sciences Trinity Medical Sciences University Kingstown Saint Vincent and Grenadines Depart.ent.of Physiology Trinity Medical Sciences University Kingstown Saint Vincent and Grenadines

Background and Purpose: Opioids, used for cent.ries t. alleviat. pain, have become a double-edged sword. While effect.ve, t.ey come wit. a host.of adverse effect., including memory and cognit.on impairment. t.is review delves int. t.e impact.of opioid drugs on cognit.ve funct.ons, explores underlying mechanisms, and invest.gat.s t.eir prevalence in bot. medical care and illicit.drug use. t.e ult.mat. goal is t. find ways t. mit.gat. t.eir pot.nt.al harm and address t.e ongoing opioid crisis. Met.ods: We sourced dat. from PubMed and Google Scholar, employing search combinat.ons like “opioids,” “memory,” “cognit.on,” “amnesia,” “cognit.ve funct.on,” “execut.ve funct.on,” and “inhibit.on.” Our focus was on English-language art.cles spanning from t.e incept.on of t.ese dat.bases up t. t.e present. Result.: t.e lit.rat.re consist.nt.y reveals t.at.opioid use, part.cularly at.high doses, adversely affect. memory and ot.er cognit.ve funct.ons. Longer deliberat.on t.mes, impaired decision-making, impulsivit., and behavioral disorders are common consequences. Chronic high-dose opioid use is associat.d wit. condit.ons such as amnesiac syndrome (OAS), post.operat.ve cognit.ve dysfunct.on (POCD), neonat.l abst.nence syndrome (NAS), depression, anxiet., sedat.on, and addict.on. Alarming t.ends show increased opioid use over recent.decades, amplifying t.e risk of t.ese out.omes. Conclusion: Opioids cast.a shadow over memory and cognit.ve funct.on. t.ese effect. range from amnesiac effect., lessened cognit.ve funct.on, depression, and more. Cont.ibut.ng fact.rs include over-prescript.on, misuse, misinformat.on, and prohibit.on policies. Focusing on correct.informat.onal campaigns, removing punit.ve policies, and focusing on harm reduct.on st.at.gies have been shown t. lessen t.e abuse and use of opioids and t.us helping t. mit.gat. t.e adverse effect. of t.ese drugs. Furt.er research int. t.e impact. of opioids on cognit.ve abilit.es is also needed as t.ey are well demonst.at.d in
