2With increasing trends of prostate cancer in the Saudi Arabia and Arab World: Should we start screening programs?显示文摘Incidence rate for prostate cancer in the Arab World is significantly lower than United States and Europe, it ranges from 5.5% to 39.2%. However, the incidence and the number of deaths is expected to increase. In Saudi Arabia, the crude incidence rate and age standardized incidence rate of prostate cancer are reported to be steadily increasing in between 2001-2008. Only two screening trials were attempted in 2001 and 2009 which yielded an incidence rate of 1.17% and 2.5% respectively. Men in the Arab world are sharing a common characteristic of poor knowledge and poor attitude towards prostate cancer examination and screening practices. They are ill-informed about the PSA test's strengths and drawbacks because the doctors are not talking to them about the importance of counselling. Men should be encouraged to do PSA testing before the age of 50 and till the age of 70 years. This could be achieved by enhancing their attitude and enriching the knowledge of the physicians towards PSA testing, harms and benefits, through shared decision making, which would increase men's knowledge scores, reduced their decisional conflict and promote greater involvement in decision making.Mostafa A Arafa Danny M Rabah 2017World Journal of Clinical Oncology2017,8,6:4
3Genotyping and pathotyping of diversified strains of infectious bronchitis viruses circulating in Egypt显示文摘AIM: To characterize the circulating infectious bronchitis virus(IBV) strains in Egypt depending on the sequence of the spike-1(S1) gene [hypervariable region-3(HVR-3)] and to study the pathotypic features of these strains.METHODS: In this work, twenty flocks were sampled for IBV detection using RRT-PCR and isolation of IBV in specific pathogen free(SPF) chicks during the period from 2010 to 2015. Partial sequencing and phylogenetic analysis of 400 bp representing the HVR-3 of the S1 gene was conducted. Pathotypic characterization of one selected virus from each group(Egy/Var-Ⅰ, Egy/Var-Ⅱ and classic) was evaluated in one day old SPF chicks. The chicks were divided into 4 groups 10 birds each including the negative control group. Birds were inoculated at one day by intranasal instillation of 105EID50/100 μL of IBV viruses [IBV-EG/1212B-2012(Egy/Var-Ⅱ), IBV/EG/IBV1-2011(Egy/Var-Ⅰ) and IBV-EG/11539F-2011(classic)], while the remaining negative control group was kept uninfected. The birds were observed for clinical signs, gross lesions and virus pathogenicity. The real-time rR TPCR test was performed for virus detection in the tissues. Histopathological examinations were evaluated in both trachea and kidneys.RESULTS: The results revealed that these viruses were separated into two distinct groups; variant(GI-23) and classic(GI-1), where 16 viruses belonged to a variant group, including 2 subdivisions [Egy/Var-Ⅰ(6 isolates) and Egy/Var-Ⅱ(10 isolates)] and 4 viruses clustered to the classic group(Mass-like). IBV isolates in the variant group were grouped with other IBV strains from the Middle East. The variant subgroup(Egy/Var-Ⅰ) was likely resembling the original Egyptian variant strain(Egypt/Beni-Suif/01) and the Israeli strain(IS/1494/2006). The second subgroup(Egy/Var-Ⅱ) included the viruses circulating in the Middle East(Ck/EG/BSU-2 and Ck/EG/BSU-3/2011) and the Israeli strain(IS/885/00). The two variant subgroups(Egy/Var-Ⅰ and Egy/Var-Ⅱ) found to be highly pathogenic to SPF chicks with mortalities up to 50% than those of the classic group which was of low virulence(10% mortality). Pathogenicity indices were 25(Egy/Var-Ⅱ), 24(Egy/Var-Ⅰ) and 8(classic); with clinical scores 3, 2 and 1 respectively.CONCLUSION: These findings indicated that the recent circulating Egyptian IBVs have multiple heterogeneous origins in marked diversifying nature of their spread, with high pathotype in specific pathogen free chicks.Ali Zanaty Abdel-Satar Arafa Naglaa Hagag Magdy El-Kady 2016World Journal of Virology2016,5,3:3
4A solution of UAV localization problem using an interacting multiple nonlinear fuzzy adaptive H_(∞)models filter algorithm显示文摘The purpose of this research is to improve the robustness of the autonomous system in order to improve the position and velocity estimation of an Unmanned Aerial Vehicle(UAV).Therefore, new integrated SINS/GPS navigation scheme based on Interacting Multiple Nonlinear Fuzzy Adaptive H_∞ Models(IMM-NFAH_∞) filtering technique for UAV is presented. The proposed IMM-NFAH_∞ strategy switches between two different Nonlinear Fuzzy Adaptive H_∞(NFAH_∞) filters and each NFAH_∞ filter is based on different fuzzy logic inference systems. The newly proposed technique takes into consideration the high order Taylor series terms and adapts the nonlinear H_∞ filter based on different fuzzy inference systems via adaptive filter bounds(di),along with disturbance attenuation parameter c. Simulation analysis validates the performance of the proposed algorithm, and the comparison with nonlinear H_∞(NH_∞) filter and that with different NFAH_∞ filters demonstrate the effectiveness of UAV localization utilizing IMM-NFAH_∞ filter.Elzoghby MOSTAFA Li FU Arafa IBRAHIM.I.

6Influence of temperature on the properties of one-dimensional piezoelectric phononic crystals显示文摘The current study investigates the influence of temperature on a one-dimensional piezoelectric phononic crystal using tunable resonant frequencies. Analytical and numerical examples are introduced to emphasize the influence of temperature on the piezoelectric phononic crystals. It was observed that the transmission spectrum of a one-dimensional phononic crystal containing a piezoelectric material(0.7 PMN-0.3 PT) can be changed drastically by an increase in temperature.The resonant peak can be shifted toward high or low frequencies by an increase or decrease in temperature, respectively.Therefore, we deduced that temperature can exhibit a large tuning in the phononic band gaps and in the local resonant frequencies depending on the presence of a piezoelectric material. Such result can enhance the harvesting energy from piezoelectric materials, especially those that are confined in a phononic crystal.Ahmed Nagaty Ahmed Mehaney Arafa H Aly 2018Chinese Physics B2018,27,9:2
7The new 6^(th) edition of the WHO Laboratory Manualfor the Examination and Processing of HumanSemen: is it a step toward better standard operatingprocedure?显示文摘Semen analysis(SA)remains the cornerstone of male infertility evaluation and should ideally be performed by an accredited andrology laboratory or in vitro fertilization(IVF)clinics based on the standards defined by the World Health Organization(WHO)for the Examination and Processing of Human Semen and in accordance with the International Organization for Standardization’s Basic Semen Examination on Specification and Test Methods.Eric Chung Mohamed Arafa Florence Boitrelle Hussein Kandil Ralf Henkel Ramadan Saleh Rupin Shah Paraskevi Vogiatzi Armand Zini Ashok Agarwal 2022Asian Journal of Andrology2022,24,2:2

9Structural damage assessment criteria for reinforced concrete buildings by using a Fuzzy Analytic Hierarchy process显示文摘Reinforced concrete structures are often exposed to many types of damages and deteriorations due to different causes and exposure conditions during their life cycle.Assessment of such structures is inherently subjected to uncertainty and ambiguity,where subjective opinion and incomplete numeric data are unavoidable.In the damage assessment process,estimating the importance of assessment criteria is an important field in itself,and depends heavily on the experience and expertise of experts.The aim of this study is to present a fuzzy-based assessment model,which estimates the importance of structural assessment criteria for concrete buildings.The work aims also at studying,identifying,and prioritizing assessment criteria.These assessment criteria are based on close visual inspections and simple measurements that do not require special testing or long-term investigation.The main assessment criteria include the state of building history,environmental conditions,structural capacity,durability,and professional involvement in construction.Each of them has two levels of sub-criteria.The criteria weights are obtained based on the opinions of experts using the Fuzzy Analytic Hierarchy Process(FAHP)method.The application of the FAHP method showed that the most important criteria is the structural capacity with a weighting factor of 50.1%,followed by the environmental condition as second,with a weighting factor of 22.5%.Khader M.Hamdia Mohammed Arafa Mamoun Alqedra 2018Underground Space2018,3,3:2
10Multi-center evaluation of oxidation-reduction potential by the MiOXSYS in males with abnormal semen显示文摘According to the World Health Organization(WHO),oxidative stress(OS)is a significant contributor to male infertility.SeminalOS can be measured by a number of assays,all of which are either costly or time sensitive and/or require large semen volume andcomplex instrumentation.One less expensive alternative is to quantify the oxidation-reduction potential(ORP)with the MiOXSYS.In this international multi-center study,we assessed whether ORP levels measured by the MiOXSYS could distinguish semensamples that fall within the 2010 WHO normal reference values from those that do not.Semen samples were collected from 2092patients in 9 countries;ORP was normalized to sperm concentration(mV/10^6 sperm/ml).Only those samples with a concentration>1×10^6 sperm ml1 were in eluded.The results showed that 199 samples fell within the WHO no rmal refere nee range while theremaining 1893 samples did not meet one or more of the criteria.ORP was negatively correlated with all semen parameters(P <0.01)except volume.The area under the curve for ORP was 0.765.The ORP cut-off value(1.34 mV/10^6 sperm/ml)was able todifferentiate specimens with abnormal semen parameters with 98.1%sensitivity,40.6%specificity,94.7%positive predictivevalue(PPV)and 66.6%negative predictive value(NPV).When used as an adjunct to traditional semen analysis,ORP levels mayhelp identify altered functional status of spermatozoa caused by OS in cases of idiopathic male infertility and in male partners ofcouples sufferi ng recurre nt pregna ncy loss,and thereby directi ng these men to relevant medical therapies and lifestyle modificati ons.Ashok Agarwal Manesh Kumar Panner Selvam Mohamed Arafa Hiroshi Okada Sheryl Homa Aideen Killeen Basak Balaban Ramadan Saleh Abdullah Armagan Shubhadeep Roychoudhury Suresh Sikka 2019Asian Journal of Andrology2019,21,6:2
