Ithini imigqa yesandla sakho kuwe, futhi unquma kanjani iminyaka yakho kusuka emigqeni yesandla sakho?

Ngokushesha odokotela bangase bakwazi ukubona uma wenza iphutha ngeminyaka yengane yakho ngenxa yobuchwepheshe obusha obuthuthukiswe ososayensi base-Taiwan. Bathola indlela yokubheka ngale kwemibimbi yomuntu ukuze banqume ubudala besikhumba sabo, futhi ngaleyo ndlela babonise iminyaka yangempela yalowo muntu.

Njengoba sikhula, isikhumba sethu siyaguga ngenxa yezici zangaphakathi, zofuzo, nezendawo ezungezile njengokukhanya kwelanga. Ukuxuba le miphumela kungasitshela ukuthi iminyaka yangempela yesikhumba somuntu inzima kakhulu, ngoba ukukhanya kwelanga kungabangela ukuguga ngaphambi kwesikhathi futhi kufihle inqubo yokuguga yemvelo.

Manje, abacwaningi baye bahola ekuhloleni lolu lwazi. "I-virtual biopsy" isebenza ngokudubula i-laser infrared pulse esheshayo nengenabuhlungu esikhumbeni. Lokhu kungena cishe ngo-0.3 mm ngongqimba olungaphandle lwesikhumba - i-epidermis - kanye nongqimba lwesikhumba olungezansi.

Abacwaningi babe sebedala amamephu e-XNUMXD esakhiwo sesikhumba besebenzisa isibonakhulu ukuze bafunde ukuthi ukukhanya kwe-laser kuhlangana kanjani namaseli esikhumba. Le nqubo ibizwa ngokuthi "i-harmonic generation biopsy" ngoba ihlaziya i-harmonics yesibili neyesithathu yokudlidliza optical okwandisa imvamisa kabili noma kathathu ubuthakathaka bokukhanya kwasekuqaleni.

Bayivivinye indlela yabo kumavolontiya angu-52, bekhomba ama-lasers ezimpahleni zangaphakathi zamavolontiya, ngokuvamile ezivikelwe elangeni, ngakho-ke kwenziwa ngezinqubo zemvelo kuphela.

Abacwaningi bathola ukuthi usayizi wohlobo oluthile lweseli yesikhumba ebizwa ngokuthi i-basal keratinocyte ikhula ngokukhula. Ngakho, ngokubheka la mangqamuzana, ososayensi bathi bangakala iminyaka evamile yesikhumba somuntu.

Lokhu kungaba usizo ekuhloleni ukusebenza kwemikhiqizo elwa nokuguga (ngokubona ukuthi ingasiza ngempela ukubambezela ukuguga kwesikhumba), kanye nasekulandeleni inqubekelaphambili ku-dermatology.
