Effects of microbial transglutaminase on the tensile properties of plastic made from soy protein isolates are studied. The results show that the tensile strength and Young modulus of the protein plastic are increased from 9.2MPa and 265.4MPa of the control, which is not treated with TG, to 14.7MPa and 390.1Mpa respective, which is treated with TG at 50℃ for 60min. High molecular weight protein conjugates are formed with TG treatment, and they are responsible for the enhanced tensile properties, denaturalizing temperature and enthalpy values.

In Part 1 of our research, BGSCs were sorted through immunomagnetic beads marking by CD133 and cultured in vitro, and character as a stem cell was identified by stem cell markers (CD133 and Nestin) and differentiated cell markers [ microtubule-associated protein 2(MAP2), glial acidic fibrillary protein and myelin basic protein] , ultrastructure observing with electron microscopeand engrafting to severe combined immunodeficiency mice for tumorigenesis test. The results were as following: Only a small subset of CD133+ glioma cells in glioma cell lines and fresh specimens from various pathologic grade could express stem cell markers CD133 and Nestin, view ultrastructure of a stem cell and be capacity of serial passage in culture. These CD133+ cells possese a marked capacity for multipotent differentiation and could differentiate into tumor cells expressing MAP2,β-TubulinⅢ, GFAP and MBP; When engrafted into SCID mice, they can generate and form tumors that phenotypically resembl the tumor from the patient.

The shorter variant mHemk2 is 1696 bp in length encoding a putative mouse protein of 14.7 kDa, consisting of 138 amino acid residues.In protein data bank annotations, Hemk has previously been classed among methyltransferases methylating N6-adenine or N4-cytidine in DNA because of the presence of S-adenosyl-L-methionine binding motif and of an NPPY motif in the protein.

在蛋白数据库的注释中，由于在Hemk蛋白中存在S-腺苷-L-甲硫氨酸结合基序和一个NPPY基序，因此，在蛋白库的说明中已经将Hemk蛋白归类于能甲基化DNA中N6-腺嘌呤或N4-胞嘧啶的甲基转移酶。

The results showed that spring wheat with plastic film mulches was able to improve the content of chlorophyll and protein of leaves in the earlier growing period and the average increase per day of the content of chlorophyll and protein of the mulched wheat increased by 31.49% and 7.94% than that of unmulched wheat respectively; but it could accelerate the decomposition of chlorophyll and protein in the later period.

BACKGROUND: Protein kinase A signaling has long been known to play an important role in cardiac function. Dysregulation of the protein kinase A system, caused by mutation of the protein kinase A regulatory subunit gene PRKAR1A, causes the inherited tumor syndrome Carney complex, which includes cardiac myxomas as one of its cardinal features.

背景：长期以来，蛋白激酶A信号途径被认为在心功能中起着重要作用，蛋白激酶A调节亚单位基因PRKAR1A的突变导致蛋白激酶A系统失调，引起遗传性肿瘤综合征－Carney合成，其中心脏粘液瘤作为其主要特征。

Background— Protein kinase A signaling has long been known to play an important role in cardiac function. Dysregulation of the protein kinase A system, caused by mutation of the protein kinase A regulatory subunit gene PRKAR1A, causes the inherited tumor syndrome Carney complex, which includes cardiac myxomas as one of its cardinal features. Mouse models of this genetic defect have been unsatisfactory because homozygote null animals die early in development and heterozygotes do not exhibit a cardiac phenotype.

背景——蛋白激酶A信号传导在心功能中发挥了重要作用早已为人们所知蛋白激酶A调节亚基因PRKAR1A的变化引起蛋白激酶A系统失调，导致了遗传性卡尼复合肿瘤综合症，其中包括的心脏粘液瘤作为它的一个主要特征此种遗传缺陷的小鼠模式仍然不能令人满意，因其纯合体空白动物在发展中早期死亡，而杂合体不能显示心脏表型
