“Konke kukhula ngokukhanya kwelanga”, ukukhanya kwelanga kuqukethe ukukhanya okuhlukahlukene, ngakunye okunobude obuhlukile, okubonisa umbala ohlukile, ngenxa yokukhanya kwayo kokujula kwezicubu kanye nezindlela ze-photobiological zihlukile, umphumela emzimbeni womuntu nawo uhlukile.
UProfesa weSikole Sezokwelapha saseHarvard uMichael Hamblin ushicilele izihloko zocwaningo ezibonisa ukuthi ukukhanya okubomvu kungadala uchungechunge lwemiphumela yokushisa, imiphumela ye-photochemical, kanye neminye imizwa yezinto eziphilayo, kanye nokujula kokungena kwezicubu zomuntu kuze kufike ku-30mm noma ngaphezulu, ngqo emithanjeni yegazi, emithanjeni ye-lymphatic, eziphethweni zemizwa, nasezicutshini ezingaphansi kwesikhumba. Ngoba ukukhanya okubomvu esikhumbeni somuntu kokungena okuphezulu, akutholakali kwamanye amaza amaza okukhanya, ngakho-ke kwaziwa ngokuthi “ifasitela lokukhanya” lesikhumba somuntu.
Umzimba umunca kanjani ukukhanya okubomvu?
Ezicutshini zomzimba wethu, ukumuncwa kokukhanya kubangelwa kakhulu amaprotheni, imibala kanye namanye ama-macromolecule kanye nama-molecule amanzi, lapho ama-molecule amanzi kanye ne-hemoglobin ebhendini lokukhanya elibomvu le-coefficient yokumuncwa kokukhanya kuncane, ama-photon angangena ngokujulile ezicutshini ukuze adlale umphumela ofanele wokwelapha, kanti ukukhanya okubomvu kanye nomzimba womuntu kuseduze kakhulu nemisebe yamagagasi kagesi, kwaziwa nangokuthi “ukukhanya kokuphila! Kwaziwa nangokuthi“ukukhanya kokuphila”.
Ukumuncwa kwamaza ahlukahlukene okukhanya yizicubu zesikhumba
Ngaphezu kwalokho, ezingeni lamaseli, i-mitochondria yizona ezimunca ukukhanya okubomvu kakhulu. I-spectrum yokukhanya okubomvu izohambisana ne-spectrum yokumunca ye-mitochondria, futhi ama-photon ayo amunca afakwa emzimbeni womuntu, okuholela ekuphenduleni kwe-photochemical biological okuphumelelayo kakhulu - ukusabela kwe-enzyme, ukuze i-mitochondrial catalase, i-superoxide dismutase kanye namanye ama-enzyme ahlobene nomsebenzi we-metabolism yamandla kuthuthukiswe, ngaleyo ndlela kusheshiswe ukwenziwa kwe-ATP, kwandiswe ukunikezwa kwamandla kwamaseli ezicubu, futhi kusheshiswe inqubo ye-metabolism kanye nokususwa kwama-metabolism anobuthi emzimbeni. Kusheshisa i-metabolism yomzimba kanye nokususwa kwama-metabolism anobuthi emzimbeni.
Ulwazi Lwangaphakathi Lwesikhungo Sokucwaninga Se-Photovoltaic saseMerican
OkunyeUcwaningo lubonisa ukuthi ukukhanya okubomvu kungashintsha ukubonakaliswa kwezakhi zofuzo ezihlobene noshukela,i-lipid, kanye ne-protein metabolism, okwenza kube lula ngama-fibroblast ukusebenzisa ama-fatty acid njengezinto zokusetshenziswa zokwenziwa kwe-ATP,ngaleyo ndlela kusheshiswe ukusebenza kwamafuthafuthi ngesikhathi esifanayo,kungenza futhi ukuvezwa kwezakhi zofuzo ezihlobene nokusetshenziswa kwamandla kulawulwe kahle, njenge-NADH dehydrogenase, i-ATP synthetase, kanye namaprotheni e-flavin adlulisa ama-electron, wLokhu kusiza ekulungiseni nasekuvuseleleni izicubu ezonakele, futhi kuvuselele izicubu zemizwa ukuze kufezwe injongo yokwelapha. Kungavuselela nezicubu zemizwa ukuze kufezwe injongo yokwelapha.
Izindlela ezingaba khona zokuvikela izinzwa ezibangelwa ukukhanya okubomvu
Imiphumela yokukhanya okubomvu emzimbeni womuntu evuselela ukukhanya
Izinkulungwane zezihloko mayelana nendlela yokukhanya okubomvu kanye nenani elikhulu lezivivinyo zemitholampilo nazo zibhale ukuthi ukukhanya okubomvu kunomthelela omkhulu ku-ubuhle, ukululama ngokomzimba, ukuthuthukiswa komzimba jikelele,njll., nokuthi idlala indima ebalulekile ekukhuthazeni ukwakheka kwe-corpus luteum yesibeletho, ilawula ibhalansi yokukhiqizwa kwama-hormone ocansi, ithuthukise umbono, yehlisa isisindo kanye namafutha, futhi ikhulule imizwa.
- Ukukhanya okubomvu kuthuthukisa ngempumelelo umbala
Ezinye izifundo zikhombisile ukuthi ukukhanya okubomvu kungavimbela umsebenzi we-tyrosinase kuama-hormone akhuthaza i-melanocyte, ngaleyo ndlelaukuvimbela ukwakheka kwe-melanin, futhi ngesikhathi esifanayo kubangele ukusebenza kwe-extracellular regulated protein kinase, kunciphisa ukuvezwa kwezinto ezihlobene nokubhalwa kwamaprotheni kanye namaprotheni e-tyrosinase, okubangela umphumela wokususa ibala, futhi kuthuthukise kakhulu izinkinga zokushintsha umbala wesikhumba,kufaka phakathi amabala ombala, izinduna, nezinye izinkinga zombala wesikhumba.
- Ukukhanya okubomvu kuthuthukisa ukumelana nokukhathala
Izazi ze-photobiology ezidumile iPassarella kanye nolunye ucwaningo bathole ukuthi ukukhanyiswa kokukhanya okubomvu imizuzu engama-20 kungathuthukisa ukugcwala komoya-mpilo egazini, futhi kunciphise i-metabolism yamaseli e-anaerobic,ukunciphisa ukukhiqizwa kwe-lactic acid enqubweni yokuzivocavoca, futhi ingakwazikwenza umzimba ube buhlungu futhi ukhathale kakhulu kunciphisa umuzwa wokukhathala, kuthuthukise ikhono lomzimba lokulwa nokukhathala kanye nokukhuthazela.
- Ukukhanya okubomvu kuthuthukisa ngempumelelo ukulahleka kokubona
Ucwaningo olusha olwenziwe ososayensi baseBrithani olushicilelwe ku-Scientific Reports luthole ukuthi ukuchayeka ku-Ukukhanya okubomvu okujulile imizuzu emithathu kuphela ngosuku kunciphisa kakhulu ukulahleka kokubona, kanti umbono wabo uthuthuka ngesilinganiso samaphesenti ayi-17.
Ukukhanya okubomvu kwansuku zonke okuqinisekiswe ngokwezokwelapha ngobuhle nempilo
Kuhle ukusho ukuthi ukwelashwa ngokukhanya okubomvu kunomlando omude. Kusukela ngo-1890, "ubaba wokukhanya okubomvu" u-NR Fenson wasebenzisa ukwelashwa ngokukhanya okubomvu ukwelapha iziguli ezine-smallpox kanye ne-lupus, esindisa izimpilo ezingenakubalwa futhi evikela ubuso obungenakubalwa. Namuhla, ucwaningo oluyisisekelo nolwezokwelapha lokwelashwa ngokukhanya okubomvu luye lwajula futhi lwandiswa ngokuphelele, futhi seluyindlela yokwelapha "engenakufakwa esikhundleni" yezifo eziningi.
Iziguli zathola ukwelashwa kokukhanya okubomvu ngekhulu le-19
Ngokusekelwe kulokhu, ithimba le-MERICAN lethule ikhabhini yokwenza mhlophe yesizukulwane sesithathu ye-MERICAN ngokusekelwe ocwaningweni lokwelashwa kokukhanya okubomvu, kuhlanganiswe nobuchwepheshe bomthombo wokukhanya ohlanganisiwe we-multi-ratio obuthuthukiswe yi-MERICAN Light Energy Research Center ngokubambisana nethimba laseJalimane, eliqondiswa ama-enzyme asebenzayo kanye ne-mitochondria ukuthuthukisa uhlelo lokujikeleza kwegazi nokulawula ibhalansi ye-metabolic, nokunciphisa umonakalo obangelwa ama-free radicals, ukuze kuqedwe ngempumelelo ukuphuzi kuma-antioxidants, kukhanyise umbala, kucwebe futhi kukhanyise isikhumba; kanye nokulungisa nokuvikela i-metabolism. Iphinde ilungise futhi ivikele i-metabolism, ukulawulwa kwamasosha omzimba kanye nezinqubo ezahlukahlukene zamaseli, ngaleyo ndlela kuthuthukiswe izinga lokuzivikela komzimba kanye nesimo sempilo esingaphansi kwempilo.
Ukuze kuqinisekiswe umphumela wayo wangempela, ithimba le-MERCAN ngaphambilini limeme amakhulu ezikhulu ezinolwazi ukuthi zenze ukuqapha kwerekhodi langempela izinsuku ezingama-28. Ngemva kokuqinisekiswa kwangempela, amakhulu ezikhulu ezinolwazi ancome kakhulu futhi aqaphela ulwazi lwe-MERCAN's 3rd Generation Whitening Chambers maqondana nokuzizwa, ubumhlophe, imizwa eduduzayo, kanye nokuqeda ubuhlungu.
