The effect of confined one-gluon-exchange potential and instanton-induced interaction potential in the singlet(1S0)and triplet(3S1)channels for nucleon–nucleon interaction has been investigated in the framework of the relativistic harmonic model using the resonating group method in the adiabatic limit with the Born–Oppenheimer *** contributions of the different components of the interaction potentials have been analyzed.

Objective:The alcoholic extract of stem bark of Terminalia arjuna（ALTA） was screened for antioxidant and antimutagenic（anticlastogenic） ***:Antioxidant property was determined by l,l,Diphynyl,2-Picryl hydrazyl（DPPH） assay,super oxide radical scavenging activity,lipid peroxidation assay and total polyphenolic content was determined by Folin-ciocalteau’s *** activity was evaluated using micronucleus test in mice. Results:The ALTA has shown potent antioxidant activity with Ec50 of 2.491±0.160,50.110±0.150 & 71.000±0.250 in DPPH assay,superoxide radical scavenging activity and lipid peroxidation assay, which is comparable with ascorbic acid with Ec50 of 2.471±0.140,40.500±0.390 and 63.000±0.360 *** micronucleus test,ALTA（100 & 200 mg/kg,p.o.） showed significant reduction in percentage of micronucleus in both polychromatic erythrocytes（PcE） and normochromatie erythrocytes（NcE） and also shown significant reduction in P/N ***:These results suggested that ALTA possess significant antioxidant and antimutagenic activity.

Spontaneous transformation of human adult non-tumorigenic stem cells to cancer stem cells is driven by genomic instability in a human model of glioblastoma

引用

中国神经肿瘤杂志 2007年第1期5卷 21-21页

作者： Shims A chettiar S Shepal V Rajendran G Prasad R shastry P National centre for cell Science （NccS） NccS complex University of Pune Campus Ganeshkhind Pune Maharashtra India.

The presence of a cD133+/Nestin+ population in brain tumors suggests that a normal neural stem cell (NSc) may be the cell of origin for gliomas. We have identified human cD133 positive NScs from adult ghoma tissue and established them as long term in vitro cultures HNGc-1 (Human Neuro Glial culture). Replicative senescence in HNGc-1 led to high level of genomie instability and emergence of a spontaneously immortalized clone that developed into a cell-line HNc_,c-2 with features of cancer stem cells (cScs) that includes ability for serf-renewal,
