| 1 | Structural Development of Northwest Saudi Arabia Using Aeromagnetic and Seismological Data显示文摘High resolution aeromagnetic and seismological data constrained by field-based structural investigations have been used to map and delineate the structural elements that affected and shaped the Midyan area in the northwest part of Saudi Arabia. The area was divided into four major domains defined by NNE, NNW, NW and ENE trending faults identified by trends, patterns and intensity of magnetic anomalies. The ENE trending left-lateral strike-slip faults intersected by NNE trending faults are the predominant tectonic features in the Gulf of Aqaba coastal area and stop at the boundary of a central domain characterized by complexity in the pattern and intensity of magnetic anomalies, that may be attributed to heterogeneity of basement rocks containing complex igneous rock suites including diorite, gabbro, ultramafic and alkali granitic rocks. This domain is characterized by the presence of narrow linear magnetic anomalies that extend for kilometers in an NNW direction, indicating dikes intruded through NNW trending faults. These dikes become WNW-oriented near their northern termination by transfer of movement to WNW-oriented faults marking the northern termination of the Red Sea rift. It is believed that this fault zone is still experiencing neotectonic activity, as evident from recorded seismicity. The aeromagnetic structural results coincide with fault plane solutions for the largest earthquakes, confirming aeromagnetic interpreted trends and illustrating mixed mechanisms between extensional and strike-slip faulting. Thus the study area displays different mechanisms associated with different tectonic trends which show clearly in the structural patterns of the area. | Mohamed Fnais Elkhedr Ibrahim Essam Abd El-Motaal Kamal Abdelrahman Abdelmaguid Al-Heniedi Khaled Al-Kahtany | 2016 | Journal of Earth Science2016，27，6： | 1 |

| 4 | Pterostilbene induces cell apoptosis and inhibits lipogenesis in SKOV3 ovarian cancer cells by activation of AMPK-induced inhibition of Akt/mTOR signaling cascade显示文摘This study investigates if the anti-tumor effect of Pterostilbene in the SKOV3 ovarian cancer(OC)cell line involves inhibition of cell metabolism and tested in this effect involves modulating AMPK and Akt-induced regulation of mTORC1.Initially,SKOV3 cells were cultured in the humidified conditions in DMEM media for 24 h with or without increasing concentration of Pterostilbene.Then,the cells were incubated with Pterostilbene(IC_(50)=50μM)under similar conditions with or without pre-incubation with Dorsomorphin,an AMPK inhibitor.In a dose-dependent manner,Pterostilbene inhibited SKOV3 cell survival and increased their lysate levels of lactate dehydrogenase(LDH)and single-stranded DNA(ssDNA).When SKOV3 cells were treated with 50μM Pterostilbene,Pterostilbene significantly suppressed cell migration and invasion,reduced lysate levels of lactic acid and the optical density of Oil Red O staining,and increased lysate glucose levels.It also increased levels of malondialdehyde(MDA),reactive oxygen species(ROS),and induced intrinsic cell apoptosis by upregulating protein levels of Bax and cleaved caspase-3 and reducing protein levels of Bcl-2.Besides,Pterostilbene reduced mRNA levels of sterol regulatory element-binding protein 1(SREBP-1),fatty acid synthase(FAS),acetyl CoA carboxylase-1(ACC-1),and AMP-activated protein kinase(AMPK).Furthermore,Pterostilbene increased the protein levels of p-AMPK,p-p53,p-raptor,p-TSC-2,but significantly decreased protein levels of p-Akt,p-TSC-2,p-mTOR,p-S6K1,and p-4E-BP.Treatment with Dorsomorphin(CC)abolished all the anti-tumorigenesis effects afforded by Pterostilbene and prevented Pterostilbene-induced phosphorylation of Akt,p53,and mTOR.In conclusion,the tumorsuppressive effect of Pterostilbene in SKOV3 cells involves the induction of ROS and inhibition of dysregulation cell metabolism mainly due to AMPK-induced Akt-dependent or independent suppression of mTOR. | ATTALLA EL-KOTT EMAN ELBEALY FAHMY ELSAID HAITHAM EL-MEKKAWY ABD-EL-KARIM ABD-LATEIF ABDULALI TAWEEL HEBA KHALIFA AHMAD KANDEEL KAREEM MORSY ESSAM IBRAHIM MASHAEL MOHAMMED BIN-MEFERIJ | 2021 | BIOCELL2021，45，1： | 0 |
