The mitochondrial isoform of creatine kinase (Mi-CK, EC 2.7.3.2) purified to homogeneity from chicken cardiac muscle by the mild and efficient technique described in this article was greater than or equal to 99.5% pure and consisted of greater than or equal to 95% of a distinct, octameric Mi-CK protein species, with a Mr of 364,000 +/- 30,000 and an apparent subunit Mr of 42,000. The remaining ...

T cells navigate complex microenvironments to initiate and modulate antigen-specific immune responses. While recent intravital microscopy study revealed that migration of T cells were guided by various tissue microstructures containing unique nanoscale topographical structures, the effects of complex nanotopographical structures on the migration of T cells have not been systematically studied. ...

Tannic acid (TA) is a polyphenolic compound with a health-promoting potential for humans. It is hypothesised that TA effects on the relative weight of internal organs and biochemical blood indices are modified by dietary protein level in rats. The study involved 72 rats divided into 12 groups fed diets with 10 or 18% of crude protein (CP) and supplemented with 0, 0.25, 0.5, 1, 1.5 or 2% of TA. ...

Introduction Rose black spot is an economically important disease that significantly decreases flower yield. Fungicide and biological control are effective approaches for controlling rose spot. The objective of this study was to evaluate the effect application chemical agents, including Bacillus velezensis (GUAL210), sp . (LKW) fungicide (CP) on rhizosphere fungal community structure edible ros...

It is clear that Ak and Bk are subsets of Ck, and in fact Lehmer [3] proved that Ak ⊂ Bk ⊂ Ck. It is not difficult to show that Cp ⊂ Ap for a prime p, so that Ap = Bp = Cp. P. J. McCarthy [5] proved that Ak = Bk when k is not squarefree, and he asked if the result could be extended to all composite numbers k. This was done by P. Erdős [2], who proved that the set Bk \ Ak is infinite for every c...

Long-term unreasonable management has led to the continuous decline of soil quality in Melaleuca alternifolia planting areas southern China, and there is no effective way improve its at present. In this study, residues tea tree oil extraction were returned forest explore influence on quality. Therefore, four test groups (RT, tiled; RS, stacked; RDT, decomposed RDS, stacked) one control group (C...

In this paper, we continue the study of the homotopy type of spaces of rational functions from S to CP begun in [3,4]. We prove that, for n > 1, Ratfc(CP ) is homotopy equivalent to Ct(R , S""), the configuration space of distinct points in R with labels in 5 2 "" 1 of length at most k. This desuspends the stable homotopy theoretic theorems of [3, 4]. We also give direct homotopy equivalences b...
