Cellae culturae ampullaesunt quaedam cellulae consumptoriae saepe in processu culturae cellae adhibitae. Cum cellulas excolentes, variae pollutiones saepe varias difficultates experiendi faciunt et processum experimenti impediunt. Quomodo ergo cum istis pollutionibus agimus?
Contaminatio plerumque causatur ab arte aseptitica impropria, incompleta sterilitate utensilium et reagentia, ac manuum vel instrumentorum transcursus super utensilium aperiendum. Postquam cellulae contaminatae sunt, pleraeque difficiles sunt ad recuperandum. Hae sunt rationes communes et curationes modos contagium cellae:
1. Contaminatio bacteria: bacteria nigra sunt subtilia harenae sub microscopio ordinario inverso. Secundum bacteria infectae diversas figuras habere possunt. Medium culturae plerumque turbidum et luteum fiet, quod insignem ictum in cellam habet incrementum. Plurimae cellulae intra 24 horas moriuntur. Correspondentes antibiotici addi possunt medio culturae, ut tetracyclinum, gentamicin, etc. Si cellulae non sunt pretiosissimae, commendatur eas abiiciendi.
2. Contaminationem fingunt: Quia vasculum culturae mediae in cella cultura patet, forma contagione difficillimum est mane deprehendere, et saepe sero est cum deprehensum est. Postquam cellulae forma contaminatae sunt, difficile est ad salvandum. Amphotericin B vel Nystatin non adiuvat. Commendatur abiiciendis cellulis contaminatis definite ac penitus disinfectibus ambitum.
3. Nigrae gummi vermis pollutionis: Nigra gummi vermes sunt bacteria nano-gradu, punctis nigris ad humilem magnificationes, et cimices nigri circa magnificationes altae natantes videri possunt. Medium culturae non est luteum et plerumque non nimium afficit. Si vero multum est, etiam incrementum cellae afficit et eventus experimentales. Cellula superstes emendari potest augendo densitatem cellae seminis.
4. Mycoplasma contagium: Mycoplasma sub microscopio inverso non apparet. In primo gradu contagionis, medium culturae non est turbidum. Post mycoplasma contagium, omnes cellae incrementum parametri afficere potest. Si talis contagione inventa est, commendatur cellas abicere et experimentum repetere.
Hae sunt plures modi communes pollutionis et curationis pro Cell culturam ampullas. Praeventionis cellae pollutionis principalis focus esse debet, et culturae locus, utensilia et culturae fluida disinfesta et sterilis esse debent. Cum operando, aseptica operationis specificationes stricte efficiunt.
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.
