Mona Hilmy Alrayes, Reham Hammad, Mohamed Abd Alazim Hussein EL Baddiny, Maha Saleh Madbouly Ibrahim, Mahmoud Hammad
Journal of Cancer Therapy (JCT) , 2019, DOI: 10.4236/jct.2019.106037
Abstract: Angiogenesis has an important role in pathophysiology of cancer. FMS-like tyrosine kinase 3 (FLT3) is implicated in hematopoietic malignancies. Their role in childhood acute lymphoblastic leukemia (ALL) pathogenesis needs more enlightenment. Expression of vascular endothelial growth factor receptor-1 and -2 (VEGFR-1 and -2), as well as FLT3 were assessed by flow cytometry in bone marrow (BM) blasts of 55 newly diagnosed children with ALL. Patients included B cell ALL (B-ALL) group (n = 41) and T cell ALL (T-ALL) group (n = 14). Comparison between groups revealed a significant increase in blasts percent (%) expressing FLT3 and FLT3 intensity detected in B-ALL group (p = 0.004 and p = 0.02, respectively). In B-ALL patients, a significant positive correlation was seen between blasts % expressing FLT3 and blasts percentage infiltrating BM (r = 0.405; p = 0.009), also positive correlation was seen between % of blasts expressing VEGFR-1 and VEGFR-2 (r = 0.704; p < 0.001). In T-ALL group, blast % expressing FLT3 revealed significant positive correlations with blast % expressing VEGFR-1, and those expressing VEGFR-2 (r = 0.627; p = 0.016, and r = 0.654; p = 0.011, respectively). In addition, significant correlation was seen in blasts % expressing all; FLT3, VEGFR-1 and -2, with blasts % expressing stem cell marker CD34 (r = 0.826; p = 0.001, r = 0.596; p = 0.041, and r = 0.798; p = 0.002, respectively). Conclusion: Expression of VEGFR-1, VEGFR-2 and FLT3 were demonstrated and linked on leukemic blasts of ALL which highlights their role in pathogenesis. FLT3 expression plays a role in facilitating blasts proliferation in BM in B-ALL. FLT3, VEGFR-1 and -2 could be used in future profiling of CD34+ leukemic stem cell pool in T-ALL.

Saleh Hadi Alharbi, Fahad A. Alateeq, Khalil Ibrahim Alshammari, Abdulaziz Saad Sharea Alshammri, Naif Abdulmohsen Naif Alabdali, Motab Ali Saud Alsulaiman, Sami Mamdouh Ibrahim Algothi, Abdulrahman Sulaiman Altoraifi, Maha Qasem Almutairi, Hussain Gadelkarim Ahmed
Health (Health) , 2019, DOI: 10.4236/health.2019.113025
Abstract: Background: dietary habit is one of the most universally recounted initiators of irritable bowel syndrome (IBS). The objective of the present study was to determine the role of some dietary habits in the etiology of IBS in Northern Saudi Arabia. Methodology: In this community based cross-sectional survey, data about IBS were obtained from 930 Saudi volunteers living in the city of Hail, Northern Saudi Arabia. IBS was diagnosed using Rome IV criteria. Results: The prevalence of IBS was 11% among males vs. 12.5% among females. The prevalence of IBS symptoms among males was 30% vs. 36.5% females. IBS was significantly associated with reduced water intake, the RR (95% CI) = 1.1800 (1.0146 to 1.3722), P = 0.0316. In the present study, the majority of the study population 904/929 (97.3%) didn’t accustom to vegetables/fruits intake. Conclusion: IBS is prevalent in Northern Saudi Arabia, both among males and females with relatively increasing among females. Low water intake and insufficient fibers intake (particularly, in vegetables and fruits) might be behind the growing prevalence of IBS in Saudi Arabia.

Global Media Journal : African Edition , 2012, DOI: 10.5789/6-1-79
Abstract: Global Media Journal, African Edition is devoted to the publication of high-quality research on Africa. Its particular focus is on understanding how media and journalism are embedded in social and cultural activities as well as the reciprocating roles between individual uses and consumption, on the one hand, and agenda building on the other hand. Such understanding requires a careful analysis of the socio-political context and the communicative processes involved.
La alfabetización mediática en Medio Oriente y Norte de áfrica: más allá del círculo vicioso del oxímoron Media Literacy in MENA: Moving Beyond the Vicious Cycle of Oxymora

Comunicar , 2009, DOI: doi:10.3916/c32-2009-02-010
Abstract: En un momento en que la región del Medio Oriente y el Norte de áfrica (MONA) está llena de potencial para el desarrollo de aptitudes, la inestabilidad social, la agitación política y las limitadas libertades civiles aún generan malestar entre la población. El desarrollo de la educación mediática en los países de la región, preocupada por muchos otros temas vitales, es bajo, en detrimento de su compromiso cívico… Las prácticas de alfabetización actual en los países de MONA tienen normas insuficientes para valorar críticamente a los medios, y los resultados de las investigaciones muestran una gran brecha entre el público en general y los periodistas, quienes desvirtúan aún más la alfabetización mediática. Este análisis trata primero de los países de MONA y su mala situación mediática , usando la figura retórica del oxímoron para explicar las diferentes tensiones y contradicciones que caracterizan a la alfabetización mediática en la región. Intenta proveer el contexto político y su relación con los medios para explicar la situación actual. Utiliza también datos de investigaciones para explorar los retos y oportunidades para cambiar la débil imagen actual de la alfabetización mediática en MONA, y concluye con varias implicaciones cruciales para el dise o de políticas de alfabetización mediática en la región. At a time when the region of Middle East and North Africa (MENA) is full of potential for capacitybuilding, social unrest, political agitation and poor civil liberties are still plaguing the population. The status of media education is low in MENA countries, preoccupied by many other vital issues, and yet the lack of it is detrimental to civic engagement… Current literacy practices in MENA countries have poor standards for critically assessing the media and research findings show a widening gap between the general public and the journalists, which further impairs media literacy. The analysis deals first with MENA countries and their mal-media situation , using the metaphor of the cycle of oxymora to explain the various tensions and contradictions that characterize media literacy in the region. It then attempts to provide a political and media-related context to explain the current situation. It also uses research data to explore the challenges and opportunities to change the current dim picture in MENA, and concludes with several crucial implications for policy-making about media literacy in MENA.
La educación en medios en Sudáfrica: Objetivos y herramientas Media and Information Literacy in South Africa: Goals and Tools

Comunicar , 2012, DOI: 10.3916/c39-2012-02-03
Abstract: El gobierno de Sudáfrica ha realizado recientemente un enorme esfuerzo en la expansión del papel de la educación en medios, con el objeto de ofrecer un acceso equitativo y de calidad a toda la población, especialmente hacia los grupos desfavorecidos. Sin embargo, este proceso requiere tiempo y recursos ingentes y constantes, además de la necesaria colaboración de otras instituciones. Actualmente, existe en Sudáfrica escasa investigación sobre las causas de las desigualdades de acceso a la tecnología o los obstáculos que existen para la difusión y puesta en marcha de la alfabetización mediática en Sudáfrica. No es sorprendente, por ello, que entre los múltiples problemas que existen hoy en áfrica todavía la alfabetización mediática e informacional no sea una prioridad. Siguen existiendo muchos maestros con escasos conocimientos en esta materia, la capacitación de formadores es muy pobre y su incorporación en programas de alfabetización muy anecdótica. El Currículum UNESCO MIL de Alfabetización Mediática es un reto para ayudar a superar esta brecha digital y promover la inclusión social. Con este objetivo, este estudio analiza algunas cuestiones relacionadas con la alfabetización mediática a partir de una muestra de estudiantes de la Universidad de Cape Town, proponiendo algunas soluciones prácticas sobre cómo ayudar a mejorar los niveles de alfabetización mediática e informacional en las sociedades menos favorecidas, como es el caso de Sudáfrica. The South African government has emphasized the need to expand the role of media education to promote equal access, with a level of quality and relevance that will empower disadvantaged groups. However, it is a challenging, time-consuming process, as well as requiring considerable and consistent expenditure and partnerships between many donor agencies. There is little research on the causes behind unequal access to technology, or comparative studies of the barriers that impede the diffusion and adoption of media and information literacy in South Africa. It is thus not surprising that the media and information literacy component is still missing from the agenda that lists Africa’s myriad problems, as well as the absence of qualified teachers, training for the trainers and the presence of IT literacy in the curricula, all of which are essential elements for any future development. The UNESCO model of curricula could help close the digital divide and promote social inclusion. As a contribution to that goal, this study investigates some of the pertinent issues related to media and information literacy via a sample o

JOURNALISM EDUCATION IN MENA: Walking on eggshells
Ibrahim Saleh
Brazilian Journalism Research , 2010,
Abstract: One of the most contradictory media scenes is the Middle East &North Africa (MENA), which is a reflection of its rather contrasting,and troubled societies that suffer from the negative effects ofimposed democracies, and the internal tripled-edged syndromesof illness, poverty and illiteracy. Using the metaphor of walkingon egg shells, the author discusses the depiction of the perplexityof the MENA in which societies just never knowing when theywill run afoul of some unknown rules, expectations, and evensuffering more when they do. Such rhetoric resonates withhow the public in MENA has become victims of the BorderlinePersonality Disorder (B.P.D.).

Cluster Structure on Generalized Weyl Algebras
Ibrahim Saleh
Mathematics , 2011,
Abstract: We introduce a class of non-commutative algebras that carry a non-commutative (geometric) cluster structure which are generated by identical copies of generalized Weyl algebras. Equivalent conditions for the finiteness of the set of the cluster variables of these cluster structures are provided. Some combinatorial data, called \textit{cluster strands,} arising from the cluster structure are used to construct irreducible representations of generalized Weyl algebras.
Induced Representations of Hopf Algebras
Ibrahim Saleh
Mathematics , 2014,
Abstract: Hopf representation is a module and comodule with a consistency condition that is more general than the consistency condition of Hopf modules. For a Hopf algebra $H$, we construct an induced Hopf representation from a representation of a bialgebra $B$ using a bialgebra epimorphism $\pi: H\rightarrow B$. Application on the quantum group $E_{q}(2)$ is given.
