Studies on the Changes of Intermediate Filament-lamina-nuclear Matrix System and Its Relations with c-myc Oncogene Expression in Normal Erythroid and Induced Murine Erythroleukemia(MEL) Cell Differentiation
The plasmids pBW34-DREB、pSPROK、pBlueks were digested with the restriction enzymes PstI/KpnI、KpnI/EcoRI、PstI/EcoRI respectively, so three fragments were obtained, and then they were ligated with T4 DNA Ligase, thus we got the medium expression vector pBWD-Tnos;
The characterization of intermediate spaces and their duals is derived from general Bernstein and Jackson inequalities.
Some attempts have been made to develop new methods.2 So in order to explore an alternative method, the key intermediate 4-benzoyloxy cyclohexanone obtained from 1,4-cyclohesanediol by its benzoylation followed by oxidation is used.
However, high (denaturing) concentrations of Me2SnCl2 (more than 9 mM) caused considerable destabilization of DNA associated with the formation of a partially unfolded intermediate at 13.6 mM of Me2SnCl2.
The formed intermediate showed a lower thermal transition temperature (Tm) by a magnitude of 10°C in relation to the native DNA.
When either a node or a link in a fault-tolerant network fails, the communication from one node to another using this faulty element must be sent via one or more intermediate nodes along a sequence of paths determined by this routing.
But several characteristics exhibited high differentiation level, such as width of the tooth of leaf base (25.99%) and the middle apical bud (25.23%).
However, only two morphological indices, the middle apical bud and the tooth of leaf base, are unstable, which indicates the extensive influence of environmental factors.
Sap flow velocity at the upper position of the trunk is higher than that of the middle and lower position, but cumulative flux is not significantly different among the upper, middle and lower sections.
Results showed that the biomass of fine roots (? 1 mm) in different layers varied in the following descending order: upper layer, middle layer and lower layer, at approximate ratios of 50:30:20.
Yunmeng belongs to the middle type, between the warm and dry northern mountain area and the warm and damp southern mountain area.
Production medium was optimized for antibiotic production.
We consider a nonlinear parabolic system describing compressible miscible displacement in a porous medium .
The objective of this paper is to deal with a kind of fuzzy linear programming problem based on interval-valued fuzzy sets (IVFLP) through the medium of procedure that turns IVFLP into parametric linear programming via the mathematical programming.
The conclusion that the equilibrium is the continuous function of the dilution rate and substrate concentration in medium in a certain range is concluded.
Many food algae and red tide algae were cultivated in the f/2 medium, and the nitric oxide (NO) concentration of the medium and the cell density were determined.
