Kev siv cov qe qe los kho osteoporosis

Cov qe tsis xav tau zoo li yog cov khoom siv tseem ceeb rau kev ua kom cov pob txha muaj kev nyab xeeb thiab zoo rau tib neeg, raws li New Atlas, hais txog phau ntawv xov xwm Smart Materials in Medicine.

Txhawm rau tsim cov khoom siv tshiab kom muaj kev nyab xeeb thiab muaj txiaj ntsig zoo ntawm pob txha grafting, cov kws tshawb fawb tau siv cov qe qaib qe, uas muaj dav thiab pheej yig.

Cov kws tshawb fawb tau tsim ib txoj kev tshiab ntawm kev sib cais thiab nag lossis daus los tsim cov amorphous calcium phosphate (ACP) hais los ntawm cov qe qaib qe, uas yog qhov tseem ceeb rau kev tsim cov pob txha pob txha - uas yog, tawv thiab muaj zog - thiab yav tas los tau siv los hloov cov pob txha. vim nws cov khoom.

Cov khoom nyoos zoo meej

Rau nws feem, tus thawj coj ntawm kev tshawb fawb, Kinali Ma, tus xibfwb ntawm Department of Biomaterials ntawm University of Oslo, tau hais tias: "Eggshells yog cov khoom siv zoo tshaj plaws rau kev tsim cov pob txha grafting cov ntaub ntawv vim tias lawv muaj ntau yam calcium. thiab phosphorus. Qee cov kab mob cuam tshuam nrog kev tsim cov pob txha, xws li magnesium thiab strontium, kuj pom muaj nyob hauv cov qe. "

Cov kws tshawb fawb tau kos cov ACP cov khoom rau hauv XNUMXD spheroid kom zoo dua los txheeb xyuas cov pob txha tsim kev ua haujlwm ntawm cov khoom los ntawm kev sib cuam tshuam ntawm cov pob txha cov ntaub so ntswg thiab cov khoom siv grafting. Lawv tau tshawb pom tias ACP cov molecules hauv cov qe hauv vitro tau cuam tshuam nrog cov hlwb uas tsim cov pob txha, nrog rau qhov zoo uas lawv tsis muaj tshuaj lom, tiv thaiv kab mob, thiab muaj txiaj ntsig zoo hauv kev txhawb nqa pob txha.

Kev cog lus technology

Harvard Justin Hauge, los ntawm University of Oslo, Norway hais tias "Lub thev naus laus zis no tau cog lus rau kev muab cov khoom siv tsis muaj kev txwv ntawm cov khoom siv bioactive thiab cov pob txha ruaj khov thaum txo cov pa phem ib puag ncig," hais tias Harvard Justin Hauge, los ntawm University of Oslo, Norway thiab tus kws tshawb fawb txog kev tshawb fawb.

Cov kws tshawb fawb vam tias lawv qhov kev tshawb pom yuav txhawb kev tshawb fawb ntxiv rau kev siv cov khoom noj khoom haus zoo tib yam li biomaterials.

Nws yog ib qho tseem ceeb uas cov txheej txheem ntawm cov pob txha grafting thoob plaws lub ntiaj teb no yog sau cov voids los yog qhov khoob hauv cov pob txha los ntawm cov pob txha graft cov ntaub ntawv los ntawm ntau qhov chaw, suav nrog autografts los ntawm cov pob txha ntawm tib neeg uas tau ua haujlwm rau, lossis los ntawm grafts los ntawm cov pob txha pub, uas yog sau thaum lub sij hawm kev phais xws li lub duav hloov uas yog sterilized rau siv nyob rau hauv lwm cov neeg mob cov pob txha grafts.

Cov pob txha grafts kuj tau muab los ntawm cov pob txha tsis muaj sia ntawm cov tsiaj xws li nyuj lossis npua, hu ua xenogeneic, uas tau ua tiav ntawm qhov kub thiab txias kom tsis muaj menyuam thiab tsis raug tso tseg los ntawm tib neeg lub cev, thiab feem ntau yog qis dua autografts lossis pub dawb.
