Stereoselective Ring-Opening Polymerization of <i>rac</i>-Lactide Using Organocatalytic Cyclic Trimeric Phosphazene Base
Phosphazene base
is an important organocatalyst in polymer chemistry
owing to its high activity and versatility. In this contribution,
we demonstrate that cyclic trimeric phosphazene base (<b>CTPB</b>) can catalyze stereoselective ring-opening polymerization (ROP)
of <i>rac</i>-lactide (<i>rac</i>-LA) to produce
isotactic stereoblock PLA (<i>P</i><sub>i</sub> up to 0.93).
The polymerizations are highly controlled, as evidenced by linear
relationship between molecular weights (MW) and monomer conversions
and the narrow dispersity (<i>Đ</i> = <i>M</i><sub>w</sub>/<i>M</i><sub>n</sub>) of the resulted polymers
with high fidelity of end groups. The investigations on polymerization
parameters show that the tacticity of produced PLA depends on the
polymerization temperatures and solvents, while the kinetic studies
reveal a faster rate for ROP of l-LA as compared to <i>rac</i>-LA under same conditions. Based on these results, the
chain end control mechanism is proposed to explain the production
of isotactic stereoblock PLA from <i>rac</i>-LA by an achiral
catalyst
Low Mfn2 expression attenuates the blastocyst formation rate and cleavage speed.
<p>In T group, the cleavage speed was reduced compared with that in control group, the blastocyst formation rate was significantly reduced in the T group compared with the C group. C1 and T1: 4-cell fertilized eggs, C2 and T2: 8-cell fertilized eggs. C3 and T3: Blastocyst. Data are means ± SD of 3 separate experiments.</p
Mfn2 expression in mouse fertilized eggs after transfection.
<p>Mfn2 mRNA expression was detected by qPCR and its level is significant lower in T group than that in C group (A). Mfn2 protein levels were determined by Western blotting (B). The quantitation of Mfn2 protein levels. C1 and T1: 4 cells fertilized eggs, C2 and T2: 8 cells fertilized eggs, C3 and T3: blastocyst. *<i>P</i><0.05.

(B) Temporal changes in proportion of location request relative to the total country-level sum of <i>N</i> for different areas as shown in (A) except TS1.</p
Multi-level quantitative comparisons between proportions of regional sum of declined and increased location request accounting for the nationwide sum for urban and rural domains, respectively, demonstrate regional imbalances in rural migrations into urban areas.
