Variable β-globin haplotypes in Saudi βthalassemia population

Open Journal of Genetics 2013年第3期3卷 171-173页

作者： Jameela Shinwari Tahani Alshehri Asma I. Tahir Abdullah Al Jefri Abdulkareem AlMomen dana Bakheet mohammad AlAnazi Arjumand Warsy Nada Al Tassan Biochemistry Department College of Science King Saud University Riyadh KSA Department of Genetics Research Centre King Faisal Specialist Hospital & Research Centre Riyadh KSA Hematology Department King Khalid University Hospital King Saud University Riyadh KSA Pediatric Hematology/Oncology Department King Faisal Specialist Hospital & Research Centre Riyadh KSA

Twenty two haplotypes were generated from a pool of 60 unrelated Saudi β thalassemia major patients using previously described restriction sites in the β globin gene. Linkage disequilibrium analysis of the polymorphic sites was also conducted, a few identified haplotypes were novel while the remainder was previously reported, haplotype1222212 was the most frequent haplotype in the study group and a strong linkage disequilibrium between two polymorphic restriction sites in these β thalassemia patients was uncovered.

Improving homomorphic wavelet estimation by compensating for residual NMO stretching on stack section

引用

Applied Geophysics 2015年第4期12卷 598-604,630页

作者： mohammad Mahdi Abedi Siyavash Torabi Department of Petroleum Engineering Amirkabir University of Technology dana Energy Group Co.

Wavelet estimation is a common step in seismic data processing and inversion. Homomorphic wavelet estimation has long utilized as a method that uses a seismic stack section with no phase presumption. Forming a stack section, normal move-out （NMO） correction must be applied on common midpoint （CMP） gathers, although it introduces NMO stretching. After stacking, residual of the NMO stretching may affect the stack section even after muting the highly stretched zone of the NMO corrected CMP gather. Presence of significant residual NMO stretching changes the spectral characteristics of data in time direction, by different degrees. Considering that in homomorphic process the wavelet is estimated based on the spectral characteristics of data, compensating for the residual NMO stretching, can improve the accuracy of the process. Here, we introduce a fast method of calculating the amount of residual NMO stretching and compensating for its effect on wavelet estimation. The proposed method needs limited prestack information like offsets and velocity function and include no prestack processing. We apply the proposed method on synthetic and real datasets and demonstrate the improvement of the estimated wavelet.

Design, Synthesis, in VitroAntibacterial Activity, and Docking Studies of New Rhodanine Derivatives

引用

Open Journal of Medicinal Chemistry 2020年第1期10卷 15-34页

Bacterial infections present a serious challenge to healthcare practitioners due to the emergence of resistance to numerous conventional antibacterial drugs. Therefore, new bacterial targets and new antimicrobials are unmet medical needs. Rhodanine derivatives are known to possess potent antimicrobial activities. In this study, we determined the activity spectrum of a series of new rhodanine derivatives against representative Gram-positive and Gram-negative bacterial strains. Compounds 3a and 5a had the highest activity with minimum inhibitory concentrations in the range of 1.12 - 2.5 μg/mL. Transmission electron microscope results confirmed that activities against bacteria occurred via rupturing of the cell wall. Molecular modeling results suggested that rhodanine derivatives have the potential to irreversibly bind to the penicillin-binding protein (PBP) Ser62 residue in the active site. Thus, our results suggested that these rhodanine derivatives could be potential antibacterial drug candidates with strong activity against Gram-negative bacteria.
