"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 kulusu 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 zomzimba wethu, 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 zincinci, ii-photons zinokungena nzulu kwi-tissues ukuze zidlale isiphumo sonyango esihambelanayo, 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-red light spectrum iya kuvakala kunye ne-absorption spectrum 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
Olunye uphando lubonisa ukuba ukukhanya okubomvu kunokutshintsha indlela ezivezwa ngayo iijini ezinxulumene neswekile, i-lipid, kunye ne-protein metabolism, okwenza kube lula ukuba ii-fibroblast zisebenzise ii-fatty acids njengezinto ezisetyenziswa ekuveliseni i-ATP, ngaloo ndlela zikhawulezise ukusebenza kwamafutha; kwaye kwangaxeshanye, kunokwenza nendlela ezivezwa ngayo iijini ezinxulumene ne-energy metabolism zilawulwe ngcono, ezifana ne-NADH dehydrogenase, i-ATP synthetase, kunye neeproteni ze-flavin ezithutha ii-electron, ezilungele ukulungisa nokuvuselela izicubu ezonakeleyo, kunye nokukhuthaza izicubu zemithambo-luvo ukufezekisa injongo yonyango. Kungavuselela nezicubu zemithambo-luvo ukufezekisa 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 ebalulekileyo kubuhle, ukubuyela emzimbeni, ukuphucula amajoni omzimba ngokubanzi, njl.njl., kwaye kudlala indima ebalulekileyo ekukhuthazeni ukwakheka kwe-corpus luteum yesibeleko, kulawula ibhalansi yokukhutshwa kweehomoni zesini, ukuphucula umbono, ukunciphisa ubunzima kunye nokutyeba, kunye nokukhulula iimvakalelo.
- Ukukhanya okubomvu kuphucula ngempumelelo umbala
Ezinye izifundo zibonise ukuba ukukhanya okubomvu kunokuthintela umsebenzi we-tyrosinaseiihomoni ezikhuthaza i-melanocyte, ngaloo ndlela kuthintela ukwenziwa kwe-melanin, kwaye kwangaxeshanye kubangele ukusebenza kwe-extracellular regulated protein kinase, kunciphisa ukubonakaliswa kwezinto ezinxulumene nokubhalwa kunye neeproteni ze-tyrosinase, okubangela isiphumo sokususa umbala, kunye nokuphucula kakhulu iingxaki zokutshintsha umbala wesikhumba, kubandakanya amabala okutshintsha umbala, i-acne, kunye nezinye iingxaki zokutshintsha umbala wesikhumba.
2. Ukukhanya okubomvu kuphucula ukumelana nokudinwa
Izazinzulu ze-photobiology ezidumileyo zePassarella kunye nolunye uphando zifumanise ukuba ukukhanya okubomvu kangangemizuzu engama-20 kunokuphucula ukugcwala kweoksijini egazini, kwaye kunciphise imetabolism ye-anaerobic yeseli, ngaloo ndlela kunciphisa ukuveliswa kwe-lactic acid kwinkqubo yokuzilolonga, kwaye kunokwenza ukuba ukuqaqamba komzimba kunye nokudinwa kunciphise kakhulu imvakalelo yokudinwa, kuphucule amandla omzimba okulwa nokudinwa kunye nokunyamezela.
3. Ukukhanya okubomvu kuphucula ngempumelelo ukulahleka kokubona
Uphononongo olusandul’ ukwenzeka olwenziwe ngoososayensi baseBritane olupapashwe kwiScientific Reports lufumanise ukuba ukuchacha kukukhanya 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.
