VALUE FUNCTIONS AND ERROR BOUNDS OF TRUST REGION METHODS
Zhao, Wenling,Wang, Changyu 한국전산응용수학회 2007 Journal of applied mathematics & informatics Vol.24 No.1
This paper studies some properties of the value functions and gives some sufficient and necessary conditions about the presented global error and local error. And it leads to one kind of relationship between iterative points and optimal solution or K-T point.

The cactus-like double-shell structured SiO2@TiO2 microspheres (CDS SiO2@TiO2 microspheres) withhigh dielectric properties were successfully fabricated and utilized as high-performance electrorheological(ER)fluids and microwave absorbing materials. The SiO2 nanospheres with average diametersof 190 nm were synthesized by the hydrolysis of tetraethyl orthosilicate (TEOS), and used as the core forthefirst coating layer of TiO2 achieved by sol-gel method. Thefinal cactus-like TiO2 layer was prepared viaa hydrothermal method. The morphology of the resultant samples was characterized via transmissionelectron microscopy (TEM), scanning electron microscopy (SEM) and scanning transmission electronmicroscopy (STEM). This novel CDS SiO2@TiO2 microspheres based suspension exhibited improved ERproperties compared to conventional bare SiO2 spheres.
Characterization and Expression Profile of CMTM3/CKLFSF3
Zhong, Ji,Wang, Yu,Qiu, Xiaoyan,Mo, Xiaoning,Liu, Yanan,Li, Ting,Song, Quansheng,Ma, Dalong,Han, Wenling Korean Society for Biochemistry and Molecular Biol 2006 Journal of biochemistry and molecular biology Vol.39 No.5
CMTM/CKLFSF is a novel family of proteins linking chemokines and TM4SF. In humans, these proteins are encoded by nine genes, CKLF and CMTM1-8/CKLFSF1-8. Here we report the characteristics and expression profile of CMTM3/CKLFSF3. Human CMTM3/CKLFSF3 has a high sequence identity among various species and similar characteristics as its mouse and rat homologues. Established by results both of RT-PCR and Quantitative Real-time PCR, the gene is highly transcribed in testis, leukocytes and spleen. For further verification, we generated a polyclonal antibody against human CMTM3/CKLFSF3 and found that the protein is highly expressed in the testis and some cells of PBMCs. Therefore, CMTM3/CKLFSF3 is an evolutionarily conserved gene that may have important roles in the male reproductive system and immune system. Further studies are necessary to validate its functions in the two systems.

Human CMTM is a novel gene family consisting of CKLF and CMTM1-8. CMTM4 is the most conserved gene and has three RNA splicing forms designated as CMTM4-v1, -v2 and -v3, but in many types of tissue and cell lines, only CMTM4-v1 and -v2 could be detected. CMTM4-v2 is the full length cDNA product, which has been highly conserved during e volution. CMTM4-v1 and -v2 a re broadly expressed in normal types of tissue. They are distributed on the cell membrane and across the cytoplasm in a speckled pattern. Overexpression of CMTM4-v1 and -v2 can inhibit HeLa cell growth via G2/M phase accumulation without inducing apoptosis. Therefore, CMTM4 might be an important gene involved in cell growth and cell cycle regulation.

<P><B>Breaking Down to Build Resistance</B></P><P>Chemotherapeutic resistance often arises because of the rewiring of signaling pathways in cancer cells. Kurokawa <I>et al.</I> found that the ubiquitin E3 ligase MDM2 triggered the breakdown of another ubiquitin E3 ligase, HUWE1. In breast cancer cells that died when exposed to the HER2 (human epidermal growth factor receptor 2) EGFR (epidermal growth factor receptor) tyrosine kinase inhibitor lapatinib, MDM2 was degraded, which enabled HUWE1 to trigger the degradation of a prosurvival protein and promote assembly and activation of a protein complex required for the execution of cell death. However, MDM2 degradation did not occur in lapatinib-resistant breast cancer cells, and thus, the abundance of HUWE1 was decreased, promoting cell survival. In a mouse xenograft model, an inhibitor of MDM2 reduced the growth of tumors generated from lapatinib-resistant breast cancer cells. Thus, MDM2 could be targeted to circumvent resistance to lapatinib in breast cancers.</P>
