Doping effect on the adsorption of Na atom onto graphenes
Li-Hua Yao,Wen-Qiang Cao,Mao-Sheng Cao 한국물리학회 2016 Current Applied Physics Vol.16 No.5
We investigate the adsorption of Na atoms on pristine graphene and four types of defect graphenes using the first-principles calculations. The adsorption energies, electronic structures, Na storage capacities and the average potentials of Na atoms on different graphenes are calculated. The adsorption energies of Na atoms on B-doped, vacancy and B-doped vacancy graphenes are 1.93 eV, 2.46 eV, and 2.08 eV, respectively, which are much lower than that of Na on the pristine graphene (0.71 eV) and Na on Ndoped graphene (0.27 eV). The orbital hybridizations in the B-doped, vacancy and B-doped vacancy graphenes can be observed from the partial density of states, while there is no obvious orbital hybridization in the N-doped graphene as well as the pristine graphene. The B-doped vacancy graphene has the best Na storage capacity, while B-doped and vacancy graphenes also possess better Na storage capacities than those of the pristine graphene and N-doped graphene. This work demonstrates that the graphene introducing both B dopant and vacancy is expected to be a potential material for storing Na.

Canonical transient receptor potential channels(TRPCs) are nonselective, high calcium permeability cationicchannels. The TRPCs family includes TRPC1, TRPC2,TRPC3, TRPC4, TRPC5, TRPC6, and TRPC7. These channelsare widely expressed in the cardiovascular and nervoussystems and exist in many other human tissues and celltypes, playing several crucial roles in the human physiologicaland pathological processes. Hence, the emergenceof TRPCs modulators can help investigate these channels’applications in health and disease. It is worth noting that theTRPCs subfamilies have structural and functional similarities,which presents a signifi cant diffi culty in screening anddiscovering of TRPCs modulators. In the past few years,only a limited number of selective modulators of TRPCswere detected; thus, additional research on more potent andmore selective TRPCs modulators is needed. The presentreview focuses on the striking desired therapeutic eff ectsof TRPCs modulators, which provides intel on the structuralmodifi cation of TRPCs modulators and further pharmacologicalresearch. Importantly, TRPCs modulators cansignifi cantly facilitate future studies of TRPCs and TRPCsrelated diseases.

Possible Epithelial Ovarian Cancer Association with HPV18 or HPV33 Infection
Zhang, Pei-Pei,Zhou, Lei,Cao, Jia-Shi,Li, Yi-Ping,Zeng, Zhi,Sun, Ni,Shen, Li,Zhu, Hao-Yue,Ruan, Yang,Zha, Wen-Ting,Wang, Xin-Yu,Zhang, Ke-Qiang,Zhang, Ran Asian Pacific Journal of Cancer Prevention 2016 Asian Pacific journal of cancer prevention Vol.17 No.6
The present study was conducted to investigate the prevalence of HPV infection in epithelial ovarian cancer (EOC) in Hunan province. DNA samples were collected from paraffin embedded ovarian tissue from 322 patients with EOC, 99 with ovarian benign tumors and 199 normal persons. The polymerase chain reaction and direct sequencing were used to identify the HPV types in the samples. The relationship between the infection of human papillomavirus (HPV) and the epithelial ovarian carcinoma (EOC) was investigated combined with clinical data. The prevalence of HPV18 and HPV33 in EOC group and benign group was higher than in the normal group. HPV18 and HPV33 may play a role in the development of both EOC and ovarian benign tumor and may participate in the development of EOC with traditional risk factors, family history and abortion, possibly exerting synergistic effects.
