Uma uthuthukisa amaseli usebenzisa i-cell factory, kungangeneka ezicini ezihlukahlukene. Njengezinga lokushisa, inani le-PH, indawo yegesi, njll., lapho ingcindezi ye-osmotic nayo iyingxenye ebaluleke kakhulu.
Amaseli ezixazululo ze-hypertonic noma ze-hypotonic angashwabana noma avuvuke futhi aqhume ngokushesha. Ngakho-ke, ingcindezi ye-osmotic ingenye yezimo ezibalulekile zokutshala amaseli ku-vitro. Ukugcinwa kwengcindezi ye-osmotic yezilwane ezincelisayo kanye namanye amaseli ezicubu zezilwane ku-vitro kuhlobene kakhulu ne-NaCl, kodwa ubudlelwano bengcindezi ye-osmotic yamanye ama-dielectric abukwazi ukushaywa indiva. Ingcindezi ye-osmotic ilingana nenani lama-molecule nama-ion we-solute ngeyunithi ngayinye yevolumu ye-solvent. Ngenxa yalesi sizathu, kubaluleke kakhulu ukulawula ibhalansi ye-ion endaweni yesiko ngenani elithile nokugcina ingcindezi ye-osmotic evamile. Lokhu akukhona nje ukugcina ukungezwani kwamaseli, kodwa futhi nokulawula imetabolism yamangqamuzana. Ngenxa yokuthi ukuthuthwa kwe-ion e-extracellular kanye nokugxila kwe-ion kushintsha ukuthuthwa kwezinye izakhi (njengama-amino acid, i-sucrose, njll.), kuthinta ngokuqondile uhlelo oluyisisekelo lwamaseli. uhlobo nohlanga lwamaseli. Umfutho we-osmotic we-plasma yomuntu ungama-290 mmol/L, othathwa njengengcindezi ye-osmotic efanelekile yokuhlakulela amangqamuzana omuntu ku-vitro. Umfutho we-osmotic wamaseli ezincelisayo ngokuvamile usuka ku-290 kuye ku-300 mmol/L. Ama-embryonic lung fibroblasts angama-250-325 mmol/L, kanti amagundane angaba ngu-310 mmol/L. Ezisetshenziswa ezingokoqobo, umfutho we-osmotic ongu-260-320 mmol/L ulungele amaseli amaningi.
Ukufingqa, ukucindezela kwe-osmotic kuthinta ngokuqondile ukukhula okuvamile kwamaseli. Uma usebenzisa imboni yamaseli ukuhlakulela amangqamuzana, kuyadingeka ukugcina ingcindezi ye-osmotic efanele ngokuvumelana nezimo zamangqamuzana, ukuze kuqinisekiswe ukukhula okuhle kwamaseli.
To sum up, the osmotic pressure directly affects the normal growth of cells. When using the cell factory to cultivate cells, it is necessary to maintain an appropriate osmotic pressure according to the conditions of the cells, so as to ensure the good growth of the cells.
The FAI climbed 5.9 percent year-on-year in the first 11 months of 2018, quickening from the 5.7-percent growth in Jan-Oct, the National Bureau of Statistics (NBS) said Friday in an online statement.
The key indicator of investment, dubbed a major growth driver, hit the bottom in August and has since started to rebound steadily.
In the face of emerging economic challenges home and abroad, China has stepped up efforts to stabilize investment, in particular rolling out measures to motivate private investors and channel funds into infrastructure.
Friday's data showed private investment, accounting for more than 60 percent of the total FAI, expanded by a brisk 8.7 percent.
NBS spokesperson Mao Shengyong said funds into weak economic links registered rapid increases as investment in environmental protection and agriculture jumped 42 percent and 12.5 percent respectively, much faster than the average.
In breakdown, investment in high-tech and equipment manufacturing remained vigorous with 16.1-percent and 11.6-percent increases respectively in the first 11 months. Infrastructure investment gained 3.7 percent, staying flat. Investment in property development rose 9.7 percent, also unchanged.
