Den kontroversielle polyvagus-hypotese

Polyvagal-teorien Polyvagal-hypotesen eller -teorien (poly- "mange" + vagal "at vandre") Polyvagal-teorien er en samling af påstande om evolutionær udvikling af vagusnetven i kroppen og dens psykologiske rolle i følelsesregulering, sociale forbindelser og frygtrespons. Selvom det ikke er en teori som er almindelig anerkendt og godtaget (af state-of-the-art social-neurovidenskaben), [1] [2] [3] [4] [5] [6] er det alligevel blevet en populær teori blandt nogle læger og nogle patienter [7].

Vaccination mod Covid-19. Uddannelse af vaccinatører. Debat.

En norsk gruppe af læger har undersøgt de tre sygeplejersker under 50 år, der er og har været indlagt på Oslo Universitetshospital efter at have været vaccineret med AstraZenecas coronavaccine. En af de tre er død. Lægerne er efter undersøgelsen overbeviste om, at den stærke immunologiske reaktion er udløst som en reaktion på vaccinen, skriver norske VG. Eksperterne har arbejdet med hypotesen om, at vaccinerne udløste en uventet immunreaktion, og at kroppens system reagerede med […]

ROS – reaktive iltforbindelser – reactive oxygen species

https://en.wikipedia.org/wiki/Reactive_oxygen_species Reaktive iltarter ( ROS ) er stærkt reaktive kemiske molekyler dannet på grund af elektronens acceptabilitet af O 2 . Eksempler på ROS inkluderer peroxider , superoxid , hydroxylradikal , singlet oxygen , [3] og alfa-oxygen . Reduktionen af molekylært oxygen (O 2 ) frembringer superoxid ( • O–2), som er forløberen for de fleste andre reaktive iltarter: [4] O 2 + e – → • O–2 Adskillelse af superoxid producerer hydrogenperoxid (H 2 O 2 ): [4] 2 H + + • O–2+ • O–2→ H 2 O 2 + O 2 Hydrogenperoxid kan igen reduceres delvist og danner således hydroxidion og hydroxylradikal ( • OH) eller reduceres fuldstændigt til vand: [4] H 2 O 2 + e – → HO – + • OH 2 H + + 2 e – + H 2 O 2 → 2 H 2 O I en biologisk sammenhæng dannes ROS […]

Mitokondrier

Mitokondrier er en celleorganeller , der er omsluttet af en dobbelt membran og indeholder sin egen genetiske materiale, den mitokondriske DNA . Mitokondrier forekommer som sfæriske eller rørformede strukturer i cellerne i næsten alle eukaryoter , men ikke i prokaryoter .   På engelsk hedder de mitochondria (græsk: μίτος mitos 'tråd' og χονδρίον chondrion 'granula, korn, gryn'; [1] forældet betegnelse  chondriosome [2] ) Mitokondrier regenerere høj energi molekyle adenosintriphosphat (ATP) via respirationskæden . Ud over denne oxidative fosforylering udfører de andre vigtige opgaver for cellen, for eksempel er de involveret i dannelsen af jern-svovlklyn   Et særligt stort antal mitokondrier er placeret i celler med højt energiforbrug; Disse […]
