"Txhua yam loj hlob los ntawm lub hnub ci". Lub hnub ci muaj ntau yam teeb, txhua lub muaj qhov ntev sib txawv, qhia txog xim sib txawv. Qhov no yog vim lub teeb nkag mus tob rau hauv cov ntaub so ntswg thiab muaj cov teebmeem sib txawv rau cov tsiaj txhu.
Xibfwb Michael Hamblin ntawm Harvard Medical School tau tshaj tawm cov ntawv tshawb fawb qhia tias lub teeb liab tuaj yeem tsim ntau yam teebmeem thermal, photochemical teebmeem, thiab lwm yam kev cuam tshuam ntawm lub cev. Nws kuj tseem tuaj yeem nkag mus rau hauv tib neeg cov ntaub so ntswg txog li 30 hli lossis ntau dua, ncaj qha rau ntawm cov hlab ntsha, cov hlab ntsha lymphatic, cov hlab ntsha kawg, thiab cov ntaub so ntswg subcutaneous. Qhov no yog vim tias lub teeb liab ntawm hom no tsis pom muaj nyob rau hauv lwm hom teeb, thiab yog li ntawd hu ua "qhov rais optical" ntawm tib neeg daim tawv nqaij.
Lub cev nqus tau lub teeb liab li cas?
Hauv peb lub cev nqaij daim tawv, lub teeb feem ntau yog nqus los ntawm cov protein, cov xim, thiab lwm yam khoom loj, nrog rau cov dej molecule. Vim tias cov dej molecule thiab haemoglobin hauv lub teeb liab ntawm lub teeb nqus coefficient yog me me, cov photons tuaj yeem nkag mus tob rau hauv cov nqaij daim tawv kom muaj cov txiaj ntsig kho mob sib xws. Lub teeb liab thiab lub cev tib neeg yog qhov ze tshaj plaws rau lub zog ntawm cov nthwv dej electromagnetic, thiab tseem hu ua "lub teeb ntawm lub neej"! Nws kuj hu ua "lub teeb ntawm lub neej".
Daim Ntawv Qhia Txog Kev Tshawb Fawb Daim Ntawv Qhia 2Kev nqus cov xim sib txawv ntawm lub teeb los ntawm cov ntaub so ntawm daim tawv nqaijNtxiv rau, ntawm theem cellular, mitochondria yog cov khoom nqus loj tshaj plaws ntawm lub teeb liab. Lub spectrum teeb liab zoo ib yam li lub spectrum nqus ntawm mitochondria, thiab cov photons uas raug nqus tau raug nkag mus rau hauv lub cev tib neeg, uas ua rau muaj kev cuam tshuam zoo heev ntawm photochemical biological - ib qho kev cuam tshuam enzymatic. Qhov kev cuam tshuam no ua rau muaj kev ua haujlwm ntawm mitochondrial catalase, superoxide dismutase thiab lwm yam enzymes ntsig txog kev ua haujlwm ntawm lub zog metabolism, uas ua kom nrawm dua qhov kev tsim ntawm ATP, ua kom muaj zog ntau ntxiv rau cov hlwb nqaij thiab ua kom nrawm dua cov txheej txheem ntawm kev ua haujlwm ntawm lub cev thiab tshem tawm cov tshuaj lom metabolites ntawm lub cev. Nws ua kom lub cev ua haujlwm sai dua thiab tshem tawm cov tshuaj lom.
Mitochondria yog cov khoom nqus teeb liab loj tshaj plaws ntawm theem cellular. Lub spectrum teeb liab zoo ib yam li lub spectrum nqus ntawm mitochondria, thiab cov photons uas raug nqus tau raug nkag mus rau hauv tib neeg lub cev, uas ua rau muaj kev cuam tshuam zoo heev ntawm photochemical biological - ib qho kev cuam tshuam enzymatic. Qhov kev cuam tshuam no ua rau muaj kev ua haujlwm ntawm mitochondrial catalase, superoxide dismutase thiab lwm yam enzymes ntsig txog kev ua haujlwm ntawm lub zog metabolism, uas ua kom nrawm dua qhov kev tsim ntawm ATP, ua kom muaj zog ntau ntxiv rau cov hlwb nqaij thiab ua kom nrawm dua cov txheej txheem ntawm kev ua haujlwm ntawm lub cev thiab tshem tawm cov tshuaj lom metabolites ntawm lub cev. Nws ua kom lub cev ua haujlwm sai dua thiab tshem tawm cov tshuaj lom.
Lwm txoj kev tshawb fawb qhia tau hais tias kev siv lub teeb liab tuaj yeem hloov pauv qhov kev qhia tawm ntawm cov noob caj noob ces uas cuam tshuam nrog qab zib, lipid, thiab protein metabolism, ua rau nws yooj yim dua rau fibroblasts siv cov roj fatty acids ua cov khoom siv raw rau kev tsim ATP, yog li ua kom cov rog ua haujlwm sai dua; thiab tib lub sijhawm, nws kuj tseem tuaj yeem ua rau qhov kev qhia tawm ntawm cov noob caj noob ces uas cuam tshuam nrog kev hloov pauv zog, xws li NADH dehydrogenase, ATP synthetase, thiab electron-transferring flavin proteins, uas yog qhov zoo rau kev kho thiab rov tsim cov ntaub so ntswg puas tsuaj, thiab txhawb cov ntaub so ntswg kom ua tiav lub hom phiaj kho mob. Nws kuj tseem tuaj yeem txhawb cov ntaub so ntswg kom ua tiav lub hom phiaj kho mob.
Cov txheej txheem ua tau ntawm lub teeb liab-induced neuroprotection
Cov teebmeem ntawm lub teeb liab rau tib neeg lub cev
Muaj ntau tsab xov xwm thiab kev sim tshuaj kho mob txog li cas lub teeb liab cuam tshuam rau kev zoo nkauj, kev rov zoo thiab kev tiv thaiv kab mob. Nws kuj tseem ua lub luag haujlwm tseem ceeb hauv kev txhawb nqa kev tsim ntawm lub corpus luteum hauv lub zes qe menyuam, tswj kev tso tawm cov tshuaj hormones poj niam txiv neej, txhim kho kev pom kev, poob phaus thiab rog, thiab txo kev xav.
Lub teeb liab tuaj yeem ua kom xim tawv nqaij zoo dua. Lwm cov kev tshawb fawb tau qhia tias lub teeb liab tuaj yeem thaiv qhov kev ua haujlwm ntawm tyrosinase, uas yog ib qho enzyme uas pab ua kom xim tawv nqaij. Nws kuj tseem tuaj yeem ua kom muaj protein hu ua extracellular regulated protein kinase, uas tuaj yeem txo qhov kev tsim cov tyrosinase thiab lwm cov protein cuam tshuam. Qhov no tuaj yeem pab txhim kho xim tawv nqaij thiab txo cov teeb meem pigmentation, xws li cov pob, pob txuv, thiab lwm yam xim tawv nqaij.
1. Lub teeb liab zoo txhim kho cov xim
Lub teeb liab ua rau nws yooj yim dua rau kev ua si txawm tias thaum nkees. Cov kws tshawb fawb tau pom tias lub teeb liab rau 20 feeb tuaj yeem txhim kho cov pa oxygen hauv cov ntshav thiab txo qhov kev siv lub zog anaerobic ntawm lub cev, uas ua rau cov kua qaub lactic tsawg dua thaum lub sijhawm ua si. Qhov no tuaj yeem txo qhov kev xav qaug zog thiab txhim kho lub cev lub peev xwm los tiv taus kev qaug zog thiab kev ua siab ntev.
2. Lub teeb liab txhim kho kev tiv thaiv kev qaug zog
Lub teeb liab kuj tseem tuaj yeem pab txo qhov muag tsis pom kev. Ib txoj kev tshawb fawb los ntawm cov kws tshawb fawb Askiv hauv phau ntawv xov xwm Scientific Reports pom tias kev raug lub teeb liab tob rau peb feeb hauv ib hnub tuaj yeem txo qhov muag tsis pom kev, nrog rau lawv qhov muag pom kev zoo dua los ntawm qhov nruab nrab ntawm 17 feem pua.
