ORIGINAL RESEARCH—BASIC SCIENCE: Heme Oxygenase vs. Nitric Oxide Synthase in Signaling Mediating Sildenafil Citrate Action
M. Talaat Abdel Aziz,Mohamed Farid El-Asmer,Taymour Mostafa,Samia I. Mostafa,Hazem Atta,M. Abdel Aziz Wassef,Hanan Fouad,Laila A. Rashed,Dina Sabry,Soheir Mahfouz +9 more
TL;DR: Sildenafil citrate actions may be mediated by up-regulation of HO-1 gene expression, and HO enzyme activity and cGMP levels were significantly elevated in Gr 2, accentuated in Gr 3, and significantly decreased in Gr 4 and 5 compared to controls.
Journal ArticleDOI
Putative Role of Carbon Monoxide Signaling Pathway in Penile Erectile Function
Mohamed T. Abdel Aziz,Taymour Mostafa,Hazem Atta,Mohamed A Wassef,Hanan Fouad,Laila A. Rashed,Dina Sabry +6 more
TL;DR: A review of published studies sheds a light on the significance of cavernous tissue CO signaling pathway that may pave the way for creation of therapeutic modalities based on this pathway.
Journal ArticleDOI
The role of bone marrow-derived mesenchymal stem cells in treating formocresol induced oral ulcers in dogs.
Hala El-Menoufy,Lobna Abdel Aziz Aly,Mohamed T. Abdel Aziz,Hazem Atta,Nagwa K. Roshdy,L. Rashed,Dina Sabry +6 more
TL;DR: Mesenchymal stem cells transplantation may help accelerate oral ulcer healing, possibly through the induction of angiogenesis by VEGF together with increased intracellular matrix formation as detected by increased collagen gene expression.
Journal ArticleDOI
Tissue Engineering of Necrotic Dental Pulp of Immature Teeth with Apical Periodontitis in Dogs: Radiographic and Histological Evaluation
Eman A El Ashiry,Najlaa M. Alamoudi,Mahmoud K El Ashiry,Hagar A Bastawy,Douaa A El Derwi,Hazem Atta +5 more
TL;DR: Dental pulp stem cells and growth factors incorporated in chitosan hydrogel are able to regenerate pulp- dentine like tissue and help in complete root maturation of non-vital immature permanent teeth with apical periodontitis in dogs.
Journal ArticleDOI
Heme oxygenase enzyme activity in seminal plasma of oligoasthenoteratozoospermic males with varicocele.
M. T. Abdel Aziz,Taymour Mostafa,Hazem Atta,O. Kamal,Marwa Kamel,H. Hosni,L. Rashed,Dina Sabry,F. Waheed +8 more
TL;DR: It is concluded that varicocele has a negative impact on seminal HO enzyme activity and improved seminal picture after correcting varicoCele repair might be related, in part, to improved HO action(s).
