This article concerns a ring property called pseudo-reduced-over-center that is satisfied by free algebras over commutative reduced *** properties of radicals of pseudo-reduced-over-center rings are investigated,especially related to polynomial *** is proved that for pseudo-reduced-over-center rings of nonzero characteristic,the centers and the pseudo-reduced-over-center property are preserved through factor rings modulo nil *** a locally finite ring R,it is proved that if R is pseudo-reduced-over-center,then R is commutative and R/J(R)is a commutative regular ring with J(R)nil,where J(R)is the Jacobson radical of R.

Adiponectin,a specific hormone protein secreted by adipocytes,is a protective factor in the human body and has attracted great attention due to its anti-obesity activity[1,2].The adiponectin gene(ADIPOQ),which is located on human chromosome 3q27,is a single-copy *** single-nucleotide polymorphisms(SNPs)of the human ADIPOQ play an important role in energy balance and are associated with body mass index(BMI)and obesity[3,4].Longchain polyunsaturated fatty acids(LC-PUFAs)have been identified to exert an important role during the first 1,000 days of life on infant growth,neurodevelopment,and visual *** acids,such asα-linoleic acid(ALA,C18:3n-3)and linoleic acid(LA,C18:2n-6),which cannot be synthesized de novo from other lipids,are necessary for biological *** fatty acids such as docosahexaenoic acid(DHA,C22:6n-3)and eicosapentaenoic acid(EPA,C20:5n-3)can be synthesized in neonates from their precursors(LA and ALA).Because of the very low conversion rates in the neonatal liver,it is crucial to provide adequate LC-PUFAs in the diet from early infancy.

A new convenient calcium cyanamide （CaCN2） reduction route was developed to synthesize the Eu^2＋ activated Ca-α-SiAION phosphors containing low oxygen content. The luminescence properties of the obtained products were investigated for white LEDs application. The critical Eu^2＋ concentration in various hosts and its effect on the photoluminescence properties were studied. The optimized sample （10at.% Eu^2＋ vs. Ca^2＋） could be efficiently excited by the current GaN/InGaN blue LED chips and provided emission intensity competitive with that of YAG：Ce^3＋（P46-Y3） standard, revealing that this phosphor was a potential candidate for phosphor-converted white LEDs.

OBJECTIVE： To investigate the progress in finding, isolation and culture, proliferation and differentiation, and application in neural tissue engineering of adult stem cells （ASCs）. DATA SOURCES ： Using the terms ＂adult stem cells, nerve, tissue engineering＂, we searched the PubMed for adult stem calls-related studies published in English from January 2001 to August 2006. Meanwhile, we also performed a China National Knowledge Infrastructure （CNKI） search for homochronous correlative literatures on the computer by inputting the terms ＂adult stem cells, nerve, tissue engineering＂in Chinese. STUDY SELECTION ： The materials were firstly selected. Studies related to ASCs were involved and their full texts were searched for. Inclusive criteria：（1） Literatures about the sources, distribution, culture, proliferation and differentiation, and application in the repair of neural ASCs by tissue engineering. （2）Articles recommended either by randomized, blind or by other methods were not excluded. Exclusive criteria：（1）Embryonic stem cells. （2） Review, repetitive study, case report, Meta analysis. DATA EXTRACTION： Totally 1 278 articles related to ASCs were collected, 32 were involved and the other 1 246 were excluded. DATA SYNTHESIS ： Adult stem cell has the ability of self-renewal, unceasing proliferation and transdifferentiation. It has wide source, which does not involved in ethical problems. It has advantages over embryonic stem cell. Studies on the isolation and culture, induction and differentiation and application in neural ASCs by tissue engineering contribute to obtaining considerable ASCs, so as to provide experimental and theoretical bases for the application of ASCs in repairing nerve injury in clinical practice.CONCLUSION ： ASCs play a very important role in neural tissue engineering

Although gene therapy was regarded as a promising approach for glioma treatment,its therapeutic efficacy was often disappointing because of the lack of efficient drug delivery *** stem cells(MSCs) have been reported to have a tropism for brain tumors and thus could be used as delivery vehicles for glioma ***,in this study,we attempted to treat glioma by using MSCs as a vehicle for delivering replication-competent *** firstly compared the infectivity of type 3,type 5,and type 35 fiber-modified adenoviruses in *** also determined suitable adenovirus titer in vitro and then used this titer to analyze the ability of MSCs to deliver replication-competent adenovirus into glioma in *** results indicated that type 35 fiber-modified adenovirus showed higher infectivity than did naked type 3 or type 5 fiber-modified *** carrying replication-competent adenovirus significantly inhibited tumor growth in vivo compared with other control *** conclusion,MSCs are an effective vehicle that can successfully transport replication-competent adenovirus into glioma,making it a potential therapeutic strategy for treating malignant glioma.

Flower-like TiO2 materials, with their advantages of high specific surface area, developed pore structure, and high photocatalytic activity, have been widely used in environmental management and air purification, sterilization, and surface self-cleaning, among other areas. This paper summarizes several methods used to fabricate the flower-like TiO2 nanostructures, such as the hydrothermal, solvothermal, microemulsion, sol-gel, hydrolysis, and electrodeposition oxidation methods. In addition, the morphologies, properties, and performance of different flower-like TiO2 structures are discussed. Meanwhile, the application progresses of different flower-like TiO2 structures are also analyzed.

Brucellosis is a bacterial anthropozoonosis usually caused by Brucella abortus, Brucella melitensis, Brucella suis and Brucella canis. Brucella suis, the causative agent of swine brucellosis, is classified into five biovars and preferentially infects different animal hostsIll. In China, brucellosis is a national notifiable communicable disease both in animals and in human. In 2009, 35 816 brucellosis cases were reported. The annual incidence was 2.7 per 100 000 population.
