Noj qab haus huvTshuaj

Yog vim li cas yog laus thiab tuag neeg

Ob peb cov neeg paub, tab sis nyob rau hauv lub XVIII caug xyoo, lub nruab nrab txoj sia luv tsuas yog 24 xyoo. Tom qab 100 xyoo, qhov no xov tooj tau nce los ntawm ib nrab - 48 xyoo. Tam sim no tus me nyuam yuav nyob rau nruab nrab 76 xyoo. Nrog tsis ntev los no discoveries nyob rau hauv biology, zaum ntseeg hais tias qhov no daim duab yuav ua tau ib tug ntev lub sij hawm tas li.

kev taw qhia

Niaj hnub no, cov kev tshawb fawb rau "rejuvenating apples" thiab cov lus teb rau lo lus nug ntawm yog vim li cas laus neeg, feeb meej nyob rau hauv txoj kev tshawb no ntawm lub caj qauv ntawm hlwb, thaum tsawg mloog yog them mus rau lub luag hauj lwm ntawm kev nyuaj siab thiab kev noj haus nyob rau hauv tib neeg lub neej. Leej twg ua tau kev tsis txawj tuag tig mus anti-aging tsev kho mob, kev them nqi txhua xyoo mus rau 20 000 dollars rau lawm txoj kev kho, DNA tsom xam, thiab cosmic phais. Txawm li cas los, cov kev sim txoj kev tsis tau lees tias kev tsis txawj tuag - cia li kws txawj cog lus cas sim haum lub neej.

Ua ke, qhia rau peb paub thaum twg thiab yog vim li cas cov neeg loj hlob laus, dab tsi yog cov tsos mob thiab ua rau kev laus thiab yuav ua li cas kom qeeb tus laus txoj kev.

Lub tswvyim ntawm "laus"

Lo lus "laus muaj hnub nyoog" yog tam sim no txuam nrog anti-laus tshuaj pleev ib ce thiab kev phais. Qhov no yog vim lub fact tias niaj hnub science yog ntau focused rau txoj kev tshawb no ntawm txheej chaw thiab cov invention ntawm tshiab technologies. Hais txog kev tsis txawj tuag tsuas tsis nco qab lawm.

Tab sis Doktor Dzhon Langmore, xib fwb nyob rau hauv lub University of Michigan, thiab nws pab neeg "ntsia" rau hauv lub hlwb, tus essence heev ntawm tib neeg lub neej. Nyob rau hauv kev, nws tau kawm thiab sab DNA molecule nyob rau hauv nws xaus saw ntawm repeating officers ntawm enzymes uas tau tom qab ua ib "telomere". Lawv ua hauj lwm raws li ib tug tiv thaiv "kaus mom" nyob rau thaum xaus ntawm chromosomes uas tiv thaiv molecules lub sij hawm, tau phua nyob rau hauv ib nrab, uas ua rau yus laus thiab tuag txiv neej.

Yuav ua li cas yog lub "telomeres"

Zaum nco ntsoov tias thaum ib tug neeg tau txais xyoo rov saud, telomere ntev txo chains. Nws thiaj li lawv ua kom luv luv hais tias tus cell replication ua neeg tuag taus uas tsis yog uas ploj lawm daim nyob rau hauv lub DNA theem zuj zus, kev tiv thaiv lub hlwb muaj peev xwm mus hloov lawv tus kheej. Qhov no txwv tus taw tes thaum lub cell tau poob lub DNA code rau lub neej thiab yuav tsis muaj me tub nws tus kheej, nws hu ua lub Hayflick txwv. Nws yog ib qho kev ntsuas ntawm yuav ua li cas muaj ntau zaus ib lub cell tau replicate nws tus kheej, ua ntej nws tuag.

Ib txhia ntawm cov hlwb nyob rau hauv peb lub cev muaj ib tug heev Hayflick txwv. Piv txwv li, hlwb uas muaj nyob rau hauv peb lub qhov ncauj thiab hnyuv tas li erased thiab hloov. Tseeb, lawv tshwm sim yuav tsum tau loj hlob telomeres, txawm nyob rau hauv adulthood. Ces tus zaum xav nyob rau hauv yog vim li cas ib txhia hlwb inhibit qhov kev loj hlob ntawm cov telomeres nrog lub hnub nyoog, thiab ib co yog tsis.

"Programmed" hlwb

Dr. Langmore siv lub cev, biochemical thiab kev tshuaj ntsuam genetic hom kev kawm los kawm cov qauv thiab cov kev ua ntawm telomeres, tsim ib lub cell-free system rau rov qab los ntawm tej qauv ntawm telomeres siv hluavtaws DNA. Thiab kuj qhia cov mechanism uas lub telomeres yog "nyob ruaj", thiab tej yam kev mob uas ua rau lawv tsis khov.

Protein yam "lub luag hauj lwm" rau lub stabilization ntawm lub chromosome xaus tau cloned thiab kawm. Electron microscopy ua rau nws tau mus ncaj qha mus pom cov qauv ntawm cov telomeres qauv. Qhov no yog ib qho kev nthuav txoj kev tshawb no coj mus rau ntau pheej discoveries.

Zaum muaj sab ib qho tseem ceeb enzyme uas yuav "hloov tawm" cov telomere rau DNA molecule yuav infinitely tib rab diav rawg. Nws yog hu ua telomerase. Tiam sis thaum peb laus zuj zus, qhov nyiaj ntawm telomerase nyob rau hauv lub hlwb lawm. Qhov no yog cov lus teb rau lo lus nug ntawm yog vim li cas tib neeg lub cev uas muaj hnub nyoog.

Tsib loj theories

Yog li ntawd, zaum tau muaj pov thawj hais tias kev tuag tshwm sim nyob rau hauv kev twb kev txuas nrog cov tsis ntawm ib tug loj tus naj npawb ntawm hlwb. Muaj ntau ntau theories uas piav txog yuav ua li cas lub Hayflick txwv qhia nyob rau hauv lub hlwb ntawm lub cev. Xav txog lawv nyob rau hauv kom meej:

1. yuam kev hypothesis. Qhov no kev tshawb xav tias uas tsis uas tej zaum yuav tshwm sim nyob rau hauv cov tshuaj tshua nyob hauv zus tau tej cov DNA thiab RNA, raws li cov metabolic mechanism yog tsis tau 100% tseeb. Cell tuag yuav ua tau lub txiaj ntsim ntawm cov uncorrected kom raug.

2. Theory of free radicals. Nws teb rau lo lus nug ntawm yog vim li cas laus neeg, nyob rau hauv lawv tus kheej txoj kev. Tsis ceev faj dawb radicals yuav ua kev puas lub week uas koos hlwb thiab cellular DNA thiab RNA molecules. Qhov no kev puas tsuaj nws thiaj li ua rau yus lub xovtooj ntawm txoj kev tuag.

Tam sim no, qhov no kev tshawb xav fervently kawm. Sim kawm rau nas pom tau hais tias ib tug txo ntawm 40% ntawm caloric kom tsawg yuav ua rau ib tug doubling ntawm lub neej expectancy thiab txo tus naj npawb ntawm cov dawb radicals. Nyob rau hauv tas li ntawd, tus neeg tshawb fawb pom tias cov vitamins E thiab C zoo nqus lawv.

3. crosslinking kev tshawb xav hais tias cov laus uas muaj sia nyob vim lub random tsim (los ntawm crosslinking) "choj" nyob nruab nrab ntawm cov protein molecules, uas muaj peev xwm ces cuam tshuam nrog rau cov txheej txheem ntawm zus tau tej cov RNA thiab DNA. Qhov no crosslinking yuav tshwm sim los ntawm ntau yam tshuaj, feem ntau yog tshwm nyob rau hauv lub hlwb raws li ib tug tshwm sim ntawm cov metabolism hauv, raws li zoo raws li los ntawm kab mob (e.g., coj thiab haus luam yeeb).

4. hlwb hypothesis teb rau lo lus nug ntawm yog vim li cas cov neeg loj hlob laus sai sai, nyob rau hauv ib tug txawv txoj kev. Qhov no yog vim lub "ua hauj lwm" nyob rau hauv lub homeostasis ntawm lub cev functions, tshwj xeeb tshaj yog nyob rau hauv cov kev tswj ntawm lub hypothalamus rau lub pituitary caj pas, uas nyob rau hauv lem ua ib tug rhuav tshem nyob rau hauv cov kev tswj ntawm lub endocrine qog.

5. autoimmune kev tshawb xav. Nws twb npaj siab los ntawm Dr. Roy Walford nyob rau hauv Los Angeles, uas yuav qhia tau tias ob hom uas muaj protein ntau cov ntshav ntawm lub cev (B thiab T) poob lawv lub zog vim hais tias ntawm lub "nres" ntawm cov kab mob, kab mob thiab mob hlwb. Thiab thaum lub B- thiab T-hlwb ua puas, lawv kis tau noj qab nyob zoo lub hlwb.

Yog vim li cas laus neeg: ua thiab cov tsos mob

Nyob rau tej taw tes nyob rau hauv lawv lub neej, feem ntau los ze zog mus rau 30 xyoo, taw lub cim ntawm cov laus pib tau khees. Lawv yuav pom qhov txhia chaw: nyob rau hauv daim tawv nqaij wrinkles, txo lub dag lub zog thiab yooj cov pob txha thiab pob qij txha, lub plawv, lub digestive thiab tshee systems yuav hloov.

Thaum tsis muaj ib tug yuav hais raws nraim li yog vim li cas laus neeg. Tab sis mas nws nws pom tias noob caj noob ces, noj cov zaub mov, kev qoj ib ce, kab mob, thiab lwm yam cuam tshuam tus txheej txheem no.

Ua tib zoo saib cov tsos mob thiab ua rau kev laus loj systems ntawm lub cev:

1. Lub hlwb, ntaub so ntswg thiab kabmob:

- telomeres, uas yog nyob rau hauv lub xaus ntawm chromosomes nyob rau hauv txhua lub cell, nws thiaj li tiv thaiv kom txhob splitting ntawm cov DNA molecule;

- pov tseg noog nyob rau hauv lub hlwb;

- connective cov ntaub so ntswg yuav ntau txhav;

- tshaj plaws haumxeeb muaj peev xwm uas muaj ntau lub nruab nrog yog txo.

2. Lub plawv thiab cov hlab ntsha:

- lub plawv phab ntsa yuav thicker;

- lub plawv nqaij pib mus ua hauj lwm tsawg nraaj siv cov nyiaj tib cov ntshav;

- lub aorta yuav thicker, stiffer thiab tsawg saj zawg zog;

- qeeb qeeb leeg muab cov ntshav mus rau lub plawv thiab lub hlwb, uas yog vim li cas vim li cas kev laus neeg, cov cim yog cuab kev.

3. Qhov tseem ceeb nta:

- lub cev nyuaj los tswj qhov kub thiab txias;

- lub plawv dhia yuav siv sij hawm ntev mus rov qab mus rau li qub tom qab qoj ib ce.

4. Cov pob txha, cov leeg, cov pob qij txha:

- pob txha ua thinner thiab tsawg zog;

- pob qij txha - stiffer thiab tsawg saj zawg zog;

- pob txha mos nyob rau hauv cov pob txha thiab pob qij txha pib tsis muaj zog;

- lub nqaij kuj poob nws lub hwj chim, uas piav txog vim li cas laus neeg, cov ua ntawm tus txheej txheem no.

5. Digestive system:

- mob plab, siab, pancreas thiab cov hnyuv tsim significantly tsawg digestive kua;

- nws slows cia lub zog ntawm cov zaub mov los ntawm lub digestive system.

6. lub paj hlwb thiab lub paj hlwb:

- lub xov tooj ntawm paj hlwb nyob rau hauv lub hlwb thiab tus txha caj qaum yog tsis;

- nyob rau hauv lub hlwb yuav tsum tsim nyob rau txawv txav lug xws li "plaques" thiab "tangles", uas ua rau ib tug deterioration ntawm nws cov kev ua tau zoo;

- lub xov tooj ntawm kev sib txuas ntawm paj hlwb tsawg.

7. Ob lub qhov muag thiab pob ntseg:

- retina yuav thinner, thiab cov tub kawm ntawv - tougher;

- tsawg ntshiab lens;

- lub phab ntsa ntawm lub pob ntseg kwg deg ua thinner thiab eardrums - thicker.

8. Cov tawv nqaij, rau tes thiab cov plaub hau:

- daim tawv nqaij nrog lub hnub nyoog yuav thinner thiab tsawg elastic, uas yog vim li cas vim li cas cov neeg loj hlob laus nyob rau hauv tsos;

- cov hws qog tsim tsawg hws;

- rau tes loj hlob maj mam;

- plaub hau tau txais gray xim, thiab ib txhia txawm tsis txhob loj hlob.

laus cov tsos mob

Muaj ntau yam tshwm sim ntawm cov laus, uas muaj xws li cov no:

- nce nyhav rau kab mob;

- ib tug me ntsis txo nyob rau hauv txoj kev loj hlob;

- kev raug mob los ntawm tshav kub stroke los yog hypothermia;

- pob txha yooj yim mus ua txhaum;

- khoov;

- slow suab;

- yuav txo tau ntawm tag nrho cov zog;

- Cem quav thiab urinary incontinence;

- ib tug me ntsis slowing ntawm thought dab thiab nco puas;

- tsis sib haum;

- deterioration ntawm nrig txog kev pom acuity thiab txo nyob rau hauv peripheral lub zeem muag;

- tsis hnov lus;

- sagging thiab wrinkling ntawm daim tawv nqaij;

- graying plaub hau;

- poob phaus.

Tom ntej no, xav txog dab tsi yog qhov vim li cas yog vim li cas ib tug neeg yog laus, thiab zoo li cas ntawm tej yam uas ua rau peb cov laus.

cawv suab thaj

Cov neeg uas hlub cov khoom qab zib, nws yuav tsis kaj siab rau koj paub tias qab zib "leeb" peb laus laus. Yog hais tias koj haus nws nyob rau hauv loj qhov ntau, koj yuav sai sai no nce lub ceeb thawj sai sai, raws li koj lub cev yuav raug rau tus kab mob. Lawv, ntawm chav kawm, yuav qeeb "coj hauv paus" nyob rau hauv ib tug neeg lub neej rau ib ntev lub sij hawm. Txawm li cas los, txhua txhua kab mob cuam tshuam tag nrho hlwb nyob rau hauv lub cev. Thiab hais tias yog vim li cas yog vim li cas ib tug neeg yog laus maj mam.

haus luam yeeb

Txawm tias ib tug me nyuam paub tias haus luam yeeb yog teeb meem rau kev noj qab nyob. Nyob rau hauv New Zealand, piv txwv li, tuag txhua txhua xyoo 5000 cov neeg vim lub phiv los ntawm kev haus luam yeeb (xws li passive). Qhov no yog 13 cov neeg ib hnub!

Txhua luam yeeb koj haus luam yeeb yuav ntxiv wrinkles on koj lub ntsej muag. Thiab nyob rau hauv ua ke nrog nrog ntau ntawm tshav ntuj thiab tseem ua rau kom cov tsos ntawm tuag hlwb ntawm daim tawv nqaij.

kev sib nrauj

Yog, koj nyeem hais tias txoj cai! Cov kis nrog ib tug koj yuav zoo heev hlub, ntawm chav kawm, muaj ib tug tsis zoo feem tsis tsuas yog nyob rau koj puas siab puas ntsws lub xeev, tab sis kuj nyob rau hauv cov tsos thiab noj qab haus huv.

Nyob rau hauv 2009, kev soj ntsuam ua ib txoj kev kawm ntawm zoo tib yam cov menyuam ntxaib, raws li ib tug tshwm sim ntawm uas nws tau los ua tseeb tias sib cais khub niam txiv zoo npaum li cas cov laus dua li cov uas twb yeej ib txwm ua ke.

Raug lub hnub

Lub hnub lub sab muaj ib tug zoo ntxim rau cov tib neeg lub cev, tab sis mus rau ib yam twg li. Lawv muaj peev xwm ua rau lub tsos ntawm wrinkles ntawm daim tawv nqaij, ces nws yuav clear vim li cas ib txhia neeg muaj sai dua lwm tus.

Tshaj hnub tej zaum yuav ua rau elastosis (yuav txo tau ntawm daim tawv nqaij elasticity) thiab cov tsos ntawm heev heev pigmented me ntsis rau ntawm lub ntsej muag.

Phobias thiab kev nyuaj siab

Tsis ntev los no kev tshawb fawb tau pom tias tus kheej phobias thiab cwj pwm txawv leeb laus thiab ntxiv xyoo rau koj cov tsos. Mob kev nyuaj siab ua rau yus ib qhov kev tso tawm ntawm cov tshuaj hormones ntawm kev ntshai, uas muaj ib tug tsis ntxim rau cov hauv nruab nrog cev thiab cov nqaij mos. Thiab kuj pab mus rau tsim ntawm dawb radicals, uas yog vim li cas vim li cas cov neeg no laus sai heev.

Yuav ua li cas kom qeeb lom moos

Muaj ib co txheej txheem uas yuav pab tau koj nyob rau lawv tus kheej thiab tsis tau investing loj loj sums rau qeeb tus laus txoj kev nyob rau hauv lub cev:

1. Kawm yuav ua li cas tswj koj tej kev ntshai thiab tiv nrog txoj kev xav.

2. restricting calorie kom tsawg slows cia koj laus. Yam ua ntej tau ntawm cov kev tshawb fawb nyob rau hauv liab tau qhia hais tias ib tug xuas tau "qeeb" muaj hnub nyoog txog physiological kev hloov.

3. Ce tsis tu ncua. Tom qab tag nrho, lawv ua rau kom qhov kev tso tawm ntawm txoj kev loj hlob cov tshuaj hormones.

4. Sim tau txaus pw tsaug zog txhua txhua hnub. Tsuas yog thaum lub sij hawm pw tsaug zog yuav ua tau peb siab los tag nrho lawv lub zog.

5. So kom txaus. Xaiv rau qhov tsim nyog txoj kev rau koj mus so kom txaus. Tej zaum qhov no yuav ua tau seev cev, nyeem cov phau ntawv, mloog suab paj nruag los yog tsuas yog dab dej kub hom kev kawm.

Nyob rau hauv xaus, peb yuav hais tias peb txhua tus yuav txawj laus, seb peb nyiam nws los yog tsis. Tiam sis peb tam sim no paub yuav ua li cas kom qeeb tus txheej txheem, txawm nyob rau hauv lub cellular theem. Koj yuav tsum tau tsis tsuas yuav ua rau ib tug noj qab nyob zoo txoj kev ua neej, tab sis kuj yuav txo tag nrho cov yam tseem ceeb uas muaj ib tug tsis zoo feem nyob rau hauv peb lub cev.
