Uphononongo olunomdla kubo bonke abatshayayo baqinisekile ukuba into yokosa umntu inokunciphisa uxinzelelo. Abaphandi baseFransi babonise ukuba ukusebenza kwe-nicotine receptors kwiimpuku kwandisa uvakalelo lwabo kuxinzelelo. Inkqubo enokufunyanwa ebantwini.
UKUTSHAYA, INICOTINE NOXINEZELEKO
Ukuba i-vox populi iqinisekile ukuba icuba linciphisa uxinzelelo, uphononongo, olwenziwa kwiimpuku, luyaphikisana nombono wokuba icuba liyaphumla. Abaphandi abavela kwi-Neurosciences Paris-Seine laboratory (CNRS / Inserm / UPMC) kunye ne-Institute of Molecular and Cellular Pharmacology (CNRS / University of Nice Sophia Antipolis) bazama ukuvavanya impembelelo yoxinzelelo lwentlalo kwiigundane ngokusebenza okanye ngokuvimba i-nicotinic receptors. zezilwanyana. Iziphumo : iimpawu zoxinzelelo lwentlalo ziyandiswa xa iigundane zichanekile kwi-nicotine kwaye zicinezelwe xa i-receptors ivaliwe.
« Ukuba songeza i-nicotine, kuthatha usuku olunye kuphela, endaweni yeshumi, kwaye sifumana iziphumo ezifanayo ngokubhekiselele kuxinzelelo lwentlalo kwiigundane, uchaza uPhilippe Faure, umlawuli wophando kwi-CNRS. Oku kubonisa ukuba inikotini inokubangela iziphumo zoxinzelelo.« Uxinzelelo lwentlalo oluthi, kule ntonga, luqhele ukwenzeka emva kweentsuku ezilishumi xa ijongene nabalingane abandlongondlongo. Ibonakaliswa ngokuphepha kwabalingane bayo kunye nomtsalane omncinci ngokubhekiselele kwiswekile.
« Konke oku kusivumela ukuba sibonise ukuba iindlela zoxinzelelo azizimeleyo kwi-nicotinic receptor", yicacise UNjingalwazi uFaure. Ukusetyenziswa ebantwini, oku kuya kuthetha ukuba ukutshaya kwandisa imiphumo yoxinzelelo. Ngokutsho komphandi, akukho « akukho lula« ukuba iindlela ezichazwe ngempuku ziyafana ebantwini. Ukuba i-nicotine yayiza kwenza ngendlela efanayo engqondweni yethu, oku kunokuchaza indlela esisabela ngayo kwiimeko ezixinzelelekileyo ezinxulumene nobudlelwane boluntu, ngakumbi emsebenzini. Ngenxa yokuba olu xinzelelo lwentlalo alubonakali ngaphakathi kweentlobo zabantu ngokuxhatshazwa ngokuthe ngqo kwabanye abantu, okanye ngokusekwa kwe-hierarchy kunye nabalawuli, kodwa kunombono ongalunganga wendawo yethu kuluntu.
KUNYE NOKUVAKALEKA KUYO YONKE LENTO?
Isicombululo sokuziva kamnandi ngawe? Lahla imidiza yakho emgqomeni, usenokutsho. Ingxaki, ukungabikho kwe-nicotine kubangela uxinzelelo, kwaye ukutshaya kunika ingcamango yokuphumla, xa bekuya kuba yinto echaseneyo ngokutsho kophononongo. Isangqa esikhohlakeleyo siya kukwazi ukuzixhasa, ekubeni ukungabikho kwenza ukuyeka kube nzima kakhulu kwaye inikotini yonyusa uxinzelelo olufanele ukuba luthomalalise icuba. Kubantu abasebenzisa icuba ukulawula amaxhala abo, kuya kuba yimfuneko ukunyanga uxinzelelo oluveliswa yi-nicotine kunye neziphumo zokurhoxa ngokufanayo.
Abo baphethe uphononongo abazi okwangoku ukuba ngaba uxinzelelo lwentlalo kuphela, yindlela enye yoxinzelelo phakathi kwabanye, iphenjelelwa yi-nicotine. Baza kumisela ukuqonda, kusekho iimpuku, ukuba i-nicotinic receptor isebenza kangakanani kwinkqubo ye-dopaminergic. Yiyiphi imvelaphi yezilwanyana ezininzi kunye nezimo zengqondo zabantu. Into edala uxinezeleko kubudlelwane bethu nabanye, ukutshaya kusenokuba ngunobangela wezinye iingxaki zokuziphatha.
