Let H be a Hilbert space and A be a standard ＊-subalgebra of B（H）. We show that a bijective map Ф ： A →A preserves the Lie-skew product AB - BA＊ if and only if there is a unitary or conjugate unitary operator U ∈A（H） such that Ф（A） = UAU＊ for all A ∈ A, that is, Фis a linear ＊ -isomorphism or a conjugate linear ＊-isomorphism.

Modified nanosized MFI （ZSM-5 and silicalite- 1 ） zeolites were successfully synthesized by a hydrothermal method using aluminum isopropoxide and tetraethylorthosilicate as the raw materials, The synthetic zeolites were characterized by X-ray diffraction, energy dispersion spectroscopy, and scanning electron microscopy. The ZSM-5 and silicalite-1 zeolites exhibited ellipse-like and cubic columns, respectively. The K＋ ion-exchange equilibrium and ion-exchange capacity of the synthetic zeolites in seawater were investigated. The K＋ ion-exchange of synthetic zeolites was rapid and reached an ion-exchange balance in approximately 20 min. The K＋ ion-exchange capacity of ZSM-5 and silicalite-1 in seawater was 56,7 and 48.7 mg/g, respectively. The synthetic zeolites have high selectivity toward K＋, and therefore, they can be used to selectively extract potassium from seawater.

Pitting initiation and stable propagation behaviors of 2205 duplex stainless steel were investigated in the hot concentrated seawater under vacuum pressures by potentiostatic polarization. Both applied potentials and vacuum pressures greatly influence the pitting corrosion. Higher potentials lead to much faster stable pitting initiation and growth rates in both static(101.3 kPa) and dynamic(28.4 kPa) solutions. The pressure reduction can also accelerate the pitting initiation rate. However, the boiling of solution can influence the pitting propagation mechanism. The dynamic actions of boiling bubbles are unfavorable to the pit propagation and result in the formation of relatively smooth pit bottom without secondary pits.

Let X be an infinite-dimensional complex Banach space and denote by B（X） the algebra of all bounded linear operators acting on X. It is shown that a surjective additive map Φ from B（X） onto itself preserves similarity in both directions if and only if there exist a scalar c, a bounded invertible linear or conjugate linear operator A and a similarity invariant additive functional ψ on B（X） such that either Φ（T） = cATA^-1 ＋ ψ（T）I for all T, or Φ（T） = cAT＊A^-1 ＋ ψ（T）I for all T. In the case where X has infinite multiplicity, in particular, when X is an infinite-dimensional Hilbert space, the above similarity invariant additive functional ψ is always zero.

Tumor growth and metastasis are angiogenesis-dependent. Anti-angiogenic therapy represents a new strategy for the development of anti-cancer therapies. In recent years, there has been made great progress in anti-angiogenic therapy. As far as the passive immunotherapy is concerned, a recombinant humanized antibody to vascular endothelial growth factor (VEGF)— Avastin has been approved by FDA as the first angiogenesis inhibitor to treat colorectal cancer. For active specific immunotherapy, various strategies for cancer vaccines, including whole en- dothelial cell vaccines, dendritic cell vaccines, DNA vaccines, and peptides or protein vaccines, have been developed to break immune tolerance against important molecules associated with tumor angiogenesis and induce angiogenesis-specific immune responses. This article reviews the angiogenesis-targeted immunotherapy of tumor from the above two aspects.

Thermal treatments are commonly used for disinfesting chestnuts before *** is a first and sensitive quality attribute of chestnuts after thermal treatments and *** purpose of this study was to investigate L*and b*values in chestnuts during thermal treatment at 50-70°C for periods varying from 0 to 160 min,and during storage at 3°C for 5 months using a computer vision system(CVS).Results showed that the L*and b*values decreased with increasing temperature,and heating or storage *** first-order reaction model showed a better fit for the L*and b*values than zero-order reaction model with coefficients of determination(R2)ranging from 0.923 to 0.977 during the thermal treatment and *** activation energies of chestnuts were 287.19 and 347.48 kJ/mol during thermal treatments and 89.18 and 78.47 kJ/mol during storage for L*and b*values,respectively,suggesting that the yellowness(b*)was more sensitive to temperature changes than the lightness(L*).According to requirements of L*>50,a potential disinfestation treatment protocol could be developed for chestnuts at 52-62°C.
