Gusaza ni inzira karemano y’ibinyabuzima, irangwa no kugabanuka buhoro buhoro kw’imiterere n’imikorere y’umubiri uko igihe kigenda gihita. Iyi nzira iragoye kandi ishobora kwibasirwa cyane n’ingaruka zitagaragara ziturutse ku bintu bitandukanye byo hanze nko mu bidukikije. Kugira ngo basobanukirwe neza umuvuduko w’ubusaza, abahanga mu bya siyansi baretse uburyo gakondo bwo gupima imyaka cyangwa iminsi ahubwo bibanda ku gihe cyoroshye, baharanira kugera ku bumenyi buto ku bijyanye n’ubusaza.
Muri ubu bushakashatsi, abahanga mu bya siyansi bakoze urutonde rw'ibipimo by'ubusaza bifite ubuhanga, muri byo harimo imiterere ya ADN methylation ishishikaje cyane. Nk'uburyo bw'ingenzi bwo kugenzura epigenetic, imiterere ya ADN methylation ishobora kwerekana neza imiterere y'umuntu mu gusaza, ntabwo ihishura gusa impinduka zikomeye z'amakuru yerekeye gusaza, ahubwo inaba ingenzi mu bushakashatsi bwa siyansi bujyanye no gusaza. Binyuze mu isesengura ryimbitse ry'ibi bimenyetso, abahanga mu bya siyansi bashobora kubona uburyo molekile zituma gusaza bigenda neza, bagafungura inzira nshya zo gutinza gusaza no guteza imbere gusaza ku buzima.
Mu kirere kinini cy’inyenyeri z’ubumenyi bwo kurwanya gusaza, NMN (nicotinamide mononucleotide) yigeze kugaragara nk’ikimenyetso cy’inyenyeri gitangaje. Kuba ari yo yabanjirije NAD+ (nicotinamide adenine dinucleotide) byatumye abahanga mu bya siyansi bashishikarira ubushakashatsi. Ariko, uko igihe cyagendaga gihita, indi nyenyeri irabagirana, AKG (alpha-ketoglutarate), yagiye igaragara buhoro buhoro kandi imenyekana cyane mu rwego rwo kurwanya gusaza bitewe n’ubwiza bwayo budasanzwe n’ishingiro rya siyansi.
Mu bushakashatsi bwasohotse mu kinyamakuru Nature Metabolism, abahanga mu bya siyansi basobanuye uburyo AKG ikora mu bijyanye no gukora ingufu, imikorere ya mitochondrial no kurwanya gusaza. Ubu bushakashatsi bwagaragaje ko AKG ishobora guteza imbere mu buryo butaziguye uruziga rwa aside tricarboxylic no kongera ingufu mu turemangingo, bityo bikongera imbaraga muri rusange z'uturemangingo. Byongeye kandi, ikinyamakuru "Cell Metabolism" cyanasohoye ibyavuye mu bushakashatsi ku bushobozi bwa AKG bwo guteza imbere imikorere ya collagen no kunoza imiterere y'uruhu, byemeza ko ifite ubushobozi mu kurwanya gusaza.
Gusubiza inyuma ibimenyetso by'igihe
Ubushakashatsi bwakorewe mu Buyapani buduha urugero rufatika. Umugore wo mu kigero cy'imyaka yo hagati witaye ku kurwanya gusaza igihe kirekire, nyuma yo gufata imiti igabanya ubukana bwa AKG mu gihe cy'amezi atandatu, ntabwo uruhu rwe rwarushijeho kuba rwiza cyane, rurushaho gukomera no koroha, ahubwo n'ubuzima bwe muri rusange n'imiterere ye yo mu mutwe nabyo byararushijeho kuba byiza. Mu kugereranya ibimenyetso by'umubiri mbere na nyuma y'igerageza, abashakashatsi basanze imikorere y'umugore mu mitochondrial yariyongereye cyane, ibi bikaba bifitanye isano rya bugufi n'uruhare rwa AKG mu guteza imbere imikorere y'ingufu.
Umurinzi w'ubuzima bw'imitsi
Ubundi bushakashatsi bwaturutse muri Leta Zunze Ubumwe za Amerika bwibanze ku ruhare rwa AKG mu kurinda ubwonko. Nyuma yo kuvurwa na AKG, umusaza ufite ikibazo cyoroheje cyo gutekereza yagaragaje iterambere rigaragara mu bushobozi bwe bwo gutekereza, harimo no kongera kwibuka no kwibanda ku bintu. Abashakashatsi bakoresheje ikoranabuhanga ryo gufata amashusho mu bwonko babonye ko imikorere y’imitsi y’umurwayi yasubijwe mu mubiri, ibi bikaba bitanga inkunga ikomeye kuri AKG mu gukumira no kuvura indwara zitera indwara z’ubwonko.
Ibyiza byihariye bya AKG
1. Ingaruka nyinshi zo kurwanya gusaza
Bitandukanye na NMN, irwanya gusaza cyane cyane binyuze mu kongera urugero rwa NAD+, AKG igira uruhare runini mu kurwanya gusaza. Ntabwo ishobora guteza imbere gusa imikorere y'ingufu no kongera imikorere ya mitochondrial, ahubwo inanoza imiterere y'umubiri mu gusaza uhereye ku bintu byinshi binyuze mu kugira ingaruka ku imikorere y'aside amine no guteza imbere imikorere ya kolajeni.
2. Kuba ibintu bihuye neza n'umutekano biri hejuru
Kubera ko AKG ari igikoresho gisanzwe cy’umubiri w’umuntu, ifite ubushobozi bwo guhuza neza umubiri n’umutekano. Ishobora kwinjiza no gukoreshwa n’umubiri w’umuntu mu buryo butaziguye nta nzira igoye yo guhindura ibintu, bigabanya ibyago byo kugira ingaruka mbi. Ibi bituma ikoreshwa rya AKG mu rwego rwo kurwanya gusaza riba ryiza kandi rirushaho kwizerwa.
3. Ibyiza byinshi ku buzima
Uretse kurwanya gusaza, AKG inagaragaza inyungu nyinshi ku buzima mu guteza imbere ubuzima bw'imitsi no kongera ubudahangarwa bw'umubiri. Izi nyungu z'inyongera ku buzima zituma AKG irushaho gukurura abantu mu kurwanya gusaza.
Hamwe n’ubushakashatsi bwa siyansi bukomeza kwiyongera no gukomeza gutera imbere mu ikoranabuhanga, amahirwe yo gukoresha AKG mu rwego rwo kurwanya gusaza azaba menshi. Dutegereje ubushakashatsi bwiza mu gihe kizaza kugira ngo duhishure andi mayobera ya AKG, kandi twiteze ko ubushobozi bwayo bushobora guhuzwa n’izindi ngamba zo kurwanya gusaza nka NMN kugira ngo dufatanye gutanga ubwenge n’imbaraga ku buzima bw’abantu no kuramba. Muri iki gihe, AKG yagaragaje ko ifite ubushobozi bwo guhangana n’igihe kandi ikagira amahirwe menshi.
Imirimo y'ingenzi ni iyi:
Kurwanya gusaza: Bishobora gutinza cyane ibikorwa byo gusaza kw'uturemangingo binyuze mu kugenzura inzira y'ibimenyetso bya mTOR, guteza imbere autophagy, kunoza imikorere mibi ya poroteyine, no kugenzura epigenetics. Byongeye kandi, bishobora guteza imbere imikorere ya collagen, gushyigikira isuku y'uturemangingo, gufasha kugarura urugero rusanzwe rwa calcium mu maraso, kwihutisha gukira kw'ibikomere, guteza imbere gusana imitsi, n'ibindi.
Kunoza indwara zidakira: Igerageza rya muganga ryagaragaje ko bigira ingaruka nziza ku ndwara zidakira zitandukanye, harimo ariko zitagarukira gusa kuri osteoporosis, indwara z’ubwonko (nk’indwara ya Parkinson), indwara z’umutima n’imitsi, diyabete na kanseri. Bikemura by’umwihariko impamvu nyamukuru z’indwara zidakira binyuze mu gukoresha poroteyine zituma umubiri uramba kandi ugasana ADN yangiritse.
Kunoza ubudahangarwa bw'umubiri: Bishobora kongera imikorere n'ubwinshi bw'uturemangingo tw'umubiri, bikongera ubudahangarwa bw'umubiri muri rusange, bityo bigafasha umubiri kurwanya indwara n'ibindi byanduza.
Guteza imbere ubuzima: Iki gicuruzwa gifite kandi akamaro nko guteza imbere imikorere y'isukari n'ibinure mu maraso mu mubiri no gushyigikira imikorere myiza y'ubwonko, bigafasha mu kubungabunga ubuzima bw'umubiri w'umuntu muri rusange.
Ingaruka zo kurwanya gusaza zishyigikiwe n'ubushakashatsi bwa siyansi. Urugero, mu 2014, ikinyamakuru gikomeye cyitwa "Nature" cyatangaje ku nshuro ya mbere ko gusaza bishobora gutinda bitewe no kubuza imikorere ya mTOR; ubushakashatsi ku turemangingo twa osteosarcoma tw’abantu nabwo bwagaragaje ko bushobora guteza imbere autophagy; byongeye kandi, bushobora no kugira uruhare mu gukora aside amine no kugabanya metabolism ya poroteyine. Hari ibintu bitagenda neza kandi bigira uruhare mu mikorere yo kugenzura epigenetike nko gukuraho ADN.
Igeragezwa ry’ubuvuzi ryakomeje kwemeza umutekano n’imikorere yaryo. Urugero, raporo y’igerageza ry’ubuvuzi ku bantu ryakozwe n’ibitaro bya NewMed muri Kaliforuniya igaragaza ko rifite ingaruka zikomeye ku ndwara zitandukanye zidakira nko kudasinzira, kubura ubwenge, kunanirwa kw’impyiko, indwara zo mu bwonko, ndetse rikanavura kubura umwuka, umunaniro, n’ibindi bimenyetso biterwa na coronavirus nshya. Rinagira ingaruka nziza ku ndwara nk’inkorora.
Kubera ubushobozi bwayo butangaje n'umutekano wayo, yakunze kwishimirwa cyane ku isoko. Abakoresha benshi bavuze ko barushijeho kugira impinduka zikomeye mu miterere y'umubiri wabo nyuma yo kuyifata, nko kugira imbaraga nyinshi, gukomera no koroha, n'ibindi. Muri icyo gihe kandi, iki gicuruzwa cyamaze kwemerwa kandi gishyigikirwa n'inzego nyinshi zemewe n'inzobere.
Muri make, Calcium Alpha ketoglutarate ni umuti urwanya gusaza mu buryo bwa siyansi, wizewe kandi ufite akamaro. Utuma habaho ingaruka zo kurwanya gusaza kandi ukanoza ibimenyetso by'indwara zidakira zitandukanye binyuze mu buryo bwinshi. Ni amahitamo meza ku bantu baharanira ubuzima bwiza no kuramba.
