"Yonke into ikhula ngokukhanya kwelanga", ukukhanya kwelanga kuqulathe iintlobo ngeentlobo zokukhanya, nganye kuzo inobude obuhlukeneyo, ebonisa umbala owahlukileyo, ngenxa yokukhanya kwayo ubunzulu bezicubu kunye neendlela ze-photobiological zahlukile, isiphumo emzimbeni womntu naso sahlukile.
UNjingalwazi weSikolo sezonyango saseHarvard uMichael Hamblin upapashe amanqaku ophando abonisa ukuba ukukhanya okubomvu kunokuvelisa uthotho lweziphumo zobushushu, iziphumo ze-photochemical, kunye nezinye iimpendulo zebhayoloji, kunye nobunzulu bokungena kwezicubu zomntu ukuya kuthi ga kwi-30mm okanye ngaphezulu, ngokuthe ngqo kwimithambo yegazi, kwimithambo ye-lymphatic, kwiziphelo zemithambo-luvo, nakwizicubu ezingaphantsi komhlaba. Ngenxa yokuba ukukhanya okubomvu eluswini lomntu kokungena okuphezulu, akufumaneki kwezinye ii-wavelengths zamaza okukhanya, kwaye ke ngoko kwaziwa ngokuba yi-"optical window" yolusu lomntu.
Ukukhanya okubomvu kufunxwa njani ngumzimba?
Kwizicwili zethu zomzimba, ukufunxwa kokukhanya kubangelwa kakhulu ziiproteni, ii-pigment kunye nezinye ii-macromolecules kunye nee-molecules zamanzi, apho ii-molecules zamanzi kunye ne-hemoglobin kwi-red light band ye-light absorption coefficient incinci, ii-photons zinokungena nzulu kwi-tissues ukuze zidlale isiphumo sonyango esifanelekileyo, kwaye ukukhanya okubomvu kunye nomzimba womntu kukufutshane kakhulu nemitha yamaza e-electromagnetic, kwaziwa ngokuba "kukukhanya kobomi! Kwaziwa ngokuba“ukukhanya kobomi”.
Ukufunxwa kweengqimba ezahlukeneyo zokukhanya ziithishu zolusu
Ukongeza, kwinqanaba leeseli, i-mitochondria zezona zifunxa ukukhanya okubomvu zinkulu. I-spectrum yokukhanya okubomvu iya kuvakala kunye ne-spectrum yokufunxa ye-mitochondria, kwaye ii-photons zayo ezifunxayo zingeniswa emzimbeni womntu, nto leyo ebangela ukuba kubekho i-photochemical biological reaction esebenza kakuhle kakhulu - i-enzyme reaction, ukuze i-mitochondrial catalase, i-superoxide dismutase kunye nezinye ii-enzymes ezinxulumene nomsebenzi we-energy metabolism ziphuculwe, ngaloo ndlela kukhawuleziswe ukwenziwa kwe-ATP, kwandiswe ukunikezelwa kwamandla kwiiseli zezicubu, kwaye kukhawuleziswe inkqubo ye-metabolism kunye nokususwa kwee-metabolites ezinobuthi emzimbeni. Ikhawulezisa i-metabolism yomzimba kunye nokususwa kwee-metabolites ezinobuthi emzimbeni.
Ulwazi lwangaphakathi lweZiko loPhando lwePhotovoltaic laseMerican
Enyeuphando lubonisa ukuba ukukhanya okubomvu kunokutshintsha indlela ezibonakala ngayo ii-genes ezinxulumene neswekile,i-lipid, kunye ne-protein metabolism, okwenza kube lula kwi-fibroblasts ukusebenzisa ii-fatty acids njengezinto ezisetyenziswa ekuhlanganiseni i-ATP,ngaloo ndlela kukhawuleziswa ukusebenza kwamafuthakwaye ngexesha elinye,inokwenza ukubonakaliswa kwezakhi zofuzo ezinxulumene nemetabolism yamandla kulawulwe ngcono, njenge-NADH dehydrogenase, i-ATP synthetase, kunye neeproteni ze-flavin ezidlulisela ii-electron, wOku kunceda ekulungiseni nasekuvuseleleni izicubu ezonakeleyo, kwaye kukhuthaze izicubu zemithambo-luvo ukuze kufezekiswe injongo yonyango. Kungakhuthaza nezicubu zemithambo-luvo ukuze kufezekiswe injongo yonyango.
Iindlela ezinokwenzeka zokukhusela i-neuroprotection ebangelwa kukukhanya okubomvu
Iziphumo zokushukumisa ukukhanya okubomvu emzimbeni womntu
Amashumi amawaka amanqaku malunga nendlela yokukhanya okubomvu kunye nenani elikhulu lezilingo zeklinikhi nazo zibonise ukuba ukukhanya okubomvu kunempembelelo ebalulekileyoubuhle, ukuchacha emzimbeni, ukomelezwa komzimba ngokubanzi,njl., kwaye idlala indima ebalulekileyo ekukhuthazeni ukwakheka kwe-corpus luteum yesibeleko, ilawula ulungelelwaniso lokukhutshwa kweehomoni zesini, iphucula umbono, yehlisa ubunzima kunye nokutyeba, kwaye ikhulula iimvakalelo.
- Ukukhanya okubomvu kuphucula ngempumelelo umbala
Ezinye izifundo zibonise ukuba ukukhanya okubomvu kunokuthintela umsebenzi we-tyrosinaseiihomoni ezikhuthaza i-melanocyte, ngoko keukuthintela ukwenziwa kwe-melanin, kwaye kwangaxeshanye zikhuthaza ukusebenza kwe-extracellular regulated protein kinase, zinciphisa ukubonakaliswa kwezinto ezinxulumene nokubhalwa kunye neeproteni ze-tyrosinase, zibangela isiphumo sokususa umbala, kwaye ziphucule kakhulu iingxaki zokutshintsha umbala wesikhumba,kuquka amabala ombala, i-acne, kunye nezinye iingxaki zombala wolusu.
- Ukukhanya okubomvu kuphucula ukumelana nokudinwa
I-photobiology edumileyo izazinzulu zePassarella kunye nolunye uphando zifumanise ukuba ukukhanya okubomvu imizuzu engama-20 kunokuphucula ukugcwala kweoksijini egazini, kwaye kunciphise imetabolism ye-anaerobic yeselula,ukunciphisa imveliso ye-lactic acid kwinkqubo yokuzilolonga, kwaye unakoyenza umzimba ube buhlungu kwaye udinwe kakhulu kunciphisa imvakalelo yokudinwa, kuphucula amandla omzimba okulwa nokudinwa kunye nokunyamezela.
- Ukukhanya okubomvu kuphucula ngempumelelo ukulahleka kokubona
Uphando olusandul’ ukwenzeka olwenziwe ngoososayensi baseBritane olupapashwe kwiScientific Reports lufumanise ukuba ukuvezwa kuUkukhanya okubomvu okunzulu imizuzu emithathu kuphela ngosuku kunciphisa kakhulu ukulahleka kokubona, kwaye umbono wabo uphucuka ngomyinge we-17 ekhulwini.
Ukukhanya okubomvu kwemihla ngemihla okuqinisekisiweyo ngokwezonyango kubuhle nempilo
Kufanelekile ukukhankanya ukuba unyango lokukhanya okubomvu lunembali ende. Kwangoko ngo-1890, "uyise wokukhanya okubomvu" u-NR Fenson wayesebenzisa unyango lokukhanya okubomvu ukunyanga izigulane ezine-smallpox kunye ne-lupus, esindisa ubomi obungenakubalwa kwaye ekhusela ubuso obungenakubalwa. Kule mihla, uphando olusisiseko nolweklinikhi lonyango lokukhanya okubomvu luye lwanzulu kwaye lwandiswa ngokupheleleyo, kwaye luye lwaba lunyango "olungenakutshintshwa" lwezifo ezininzi.
Izigulana zafumana unyango olubomvu ngenkulungwane ye-19
Ngokusekelwe koku, iqela le-MERICAN liqalise ikhabhini yesizukulwana sesithathu se-MERICAN yokwenza mhlophe ngokusekelwe kuphando lwe-red light therapy, kunye netekhnoloji yomthombo wokukhanya odibeneyo we-multi-ratio eyenziwe yi-MERICAN Light Energy Research Center ngokubambisana neqela laseJamani, elilawulwa zii-enzymes ze-pro-activation kunye ne-mitochondria ukuphucula inkqubo yokujikeleza kwegazi nokulawula ibhalansi ye-metabolic, kunye nokunciphisa umonakalo obangelwa zii-free radicals, ukuze kupheliswe ngokufanelekileyo ukutyheli kwi-antioxidants, kukhanyise umbala, kukhanye kwaye kukhanyise ulusu; kunye nokulungisa nokukhusela i-metabolism. Ikwalungisa kwaye ikhusele i-metabolism, ukulawulwa komzimba kunye neenkqubo ezahlukeneyo zeseli, ngaloo ndlela iphucula amanqanaba omzimba kunye nemeko yempilo ephantsi.
Ukuze kuqinisekiswe isiphumo sayo sokwenyani, iqela le-MERCAN liye lamema amakhulu amagosa anamava ukuba enze uhlolo lweentsuku ezingama-28 lwerekhodi yokwenyani. Emva kokuqinisekiswa kokwenyani, amakhulu amagosa anamava ancome kakhulu kwaye aqaphela amava e-MERCAN's 3rd Generation Whitening Chambers ngokubhekiselele kwiimvakalelo, ubumhlophe, iimvakalelo ezithomalalisayo, kunye nokunciphisa iintlungu.
