For the realization problem of complexes or more general spaces in Euclidean spaces we maycite the following results:1° In 1932 van Kampen proved the existence of n-dimensional complexes K not realizablein Euclidean space of dimension *** proof depends on certain invariants deduced from the reduced 2-fold symmetric productK* of *** author has pointed out that van Kampen’s invariant is merely the extreme oneof a system of invariants Φm∈Hm （K*,I（m））,（I（m）=I or I2,depending on m being even orodd）,namely Φ2n,and Φm=0 is a necessary condition for K to be realizable in *** provedalso in [2] the topological invariance of Φm,i.e.,the independence of Φm of the chosen sub-division K of the space of K,while van Kampen,in the extreme case m=2n considered by him,has not even proved its combinatorial invariance.2°In the case of differentiable manifold,Whitney（cf.e.g.,[3]） has introduced a systemof invariants which the present author has called the dual Whitney classes m,and proved that k=0,k≥m-n （1）are necessary conditions for an n-dimensional closed differentiable manifold to be realizable in Rm,3° For compact Hausdorff spaces X,Thorn has proved（[4] Th.Ⅲ.25） the followingtheorem:Let Qi be certain operations deduced from Steenrod squares,thenQi Hr （X,I2）=0,2i+r≥m （2）are necessary conditions for X to be realizable in *** operations Qi were previously intro-duced by the author by applying Smith’s theory of periodic transformations and will henceforthbe denoted by Smi（cf.[5] and [6]）.Besides,Flores got also the same results as van Kampen’s concerning the existence ofn-dimensional complexes K not realizable in ***,what he used to prove his resultsis got by imbedding the first K in R2m+1,and is actually not an invariant,but depends ingeneral on the way of realization of K in R2n+*** will be explained further in the *** the various theories listed above,not only the methods used are quite different from oneanother,but also the objects and the realization conc

Introduction Temozolomide（TMZ） provides significant benefits in the treatment of malignant glioma but many patients continue to suffer from progressive or recurrent diseases due to their tumours’ intrinsic or acquired resistance to *** employed proteomic profiling to study the global protein expression changes in TMZ-resistant malignant glioma cell-lines,and investigate the potential role of one of the identified protein candidates,prolyl 4hydroxylase,beta polypeptide（P4HB）,that may be involved in the development of acquired *** Human malignant glioma cell-lines（D54 and U87） with acquired TMZ-resistance were first developed,and their biological behaviours were characterized before protein profiling analysis by two dimensional gel electrophoresis（2DE）.Potential protein spot candidates were identified by MALDI-TOF/*** transfection with small interfering RNAs was used to knock down potential candidates to study their biological *** A total of 15 spots were identified as the most highly up-or down-regulated proteins in TMZ-resistant glioma *** these,the protein P4HB was found to be consistently dysregulated in D54 sublines of different levels of TMZ-resistance when compared to their TMZ-sensitive parental and the passage control *** expression of P4HB transcripts and proteins were also confirmed in U87 cells by qPCR and western blotting *** knock-down was found to significantly down-regulate P4HB expression,and increase TMZ-induced *** P4HB is known to play an important role in hypoxia-induced cell *** present study is the first to describe its role in the regulation of apoptosis in TMZ-treated malignant glioma cells and the development of acquired TMZ-resistance.P4HB is a potential candidate for future studies in TMZ-induced cytotoxicity and novel therapeutic strategies for the treatment of TMZ-resistant malignant glioma.
