2Epidemiology and outcome of Crohn's disease in a teaching hospital in Riyadh显示文摘AIM: To know the epidemiology and outcome of Crohn's disease at King Khalid University Hospital, Riyadh, Saudi Arabia and to compare the results from other world institutions.METHODS: A retrospective analysis of patients seen for 20 years (between 1983 and 2002). Individual case records were reviewed with regard to history, clinical, findings from colonoscopy, biopsies, small bowel enema, computerized tomography scan, treatment and outcome.RESULTS: Seventy-seven patients with Crohn's disease were revisited, 13% presented the disease in the first 10 years and 87% over the last 10 years. Thirty-three patients (42.9%) were males and 44 (57.1%) were females. Age ranged from 11-70 years (mean of 25.3+11.3 years). Ninety-two (92%) were Saudi. The mean duration of symptoms was 26+34.7 mo. The mean annual incidence of the disease over the first 10 years was 0.32:100 000 and 1.66:100 000 over the last 10 years with a total mean annual incidence of 0.94:100 000 over the last 20 years. The chief clinical features included abdominal pain, diarrhea, weight loss,anorexia, rectal bleeding and palpable mass. Colonoscopic findings were abnormal in 58 patients (76%) showing mostly ulcerations and inflammation of the colon. Eighty nine percent of patients showed nonspecific inflammation with chronic inflammatory cells and half of these patients revealed the presence of granulomas and granulations on bowel biopsies. Similarly, 69 (89%) of small bowel enema results revealed ulcerations (49%), narrowing of the bowel lumen (42%), mucosal thickening (35%) and cobblestone appearance (35%). CT scan showed abnormality in 68 (88%) of patients with features of thickened loops (66%) and lymphadenopathy (37%). Seventy-eight percent of patients had small and large bowel disease, 16% had small bowel involvement and only 6% had colitis alone. Of the total 55 (71%) patients treated with steroids at some point in their disease history, a satisfactory response to therapy was seen in 28 patients (51%) while 27 (49%) showed recurrences of the condition with mild to moderate symptoms of abdominal pain and diarrhea most of which were due to poor compliance to medication. Seven patients (33%) remained with active Crohn's disease. Nine (12%) patients underwent surgery with resections of some parts of bowel, 2 (2.5%) had steroid side effects, 6 (8%) with perianal Crohn's disease and five (6.5%) with fistulae.CONCLUSION: The epidemiological characteristics of Crohn's disease among Saudi patients are comparable to those reported from other parts of the world. However the incidence of Crohn's disease in our hospital increased over the last 10 years. The anatomic distribution of the disease is different from other world institutions with less isolated colonic affection.Abdullah S.AI-Ghamdi Ibrahim A.AI-Mofleh Rashed S.AIRashed Saleh M.AI-Amri Abdulrahman M.Aljebreen Reda EI-Badawi Arthur C.Isnani 2004World Journal of Gastroenterology2004,10,9:6

4Loading characteristics of mechanical rib bolts determined through testing and numerical modeling显示文摘Underground coal mines use mechanical bolts in addition to other types of bolts to control the rib deformation and to stabilize the yielded coal ribs.Limited research has been conducted to understand the performance of the mechanical bolts in coal ribs.Researchers from the National Institute for Occupational Safety and Health(NIOSH)conducted this work to understand the loading characteristics of mechanical bolts(stiffness and capacity)installed in coal ribs at five underground coal mines.Standard pull-out tests were performed in this study to define the loading characteristics of mechanical rib bolts.Different installation torques were applied to the tested bolts based on the strength of the coal seam.A typical tri-linear load-deformation response for mechanical bolts was obtained from these tests.It was found that the anchorage capacity depended mainly on the coal strength.Guidelines for modeling mechanical bolts have been developed using the tri-linear load-deformation response.The outcome of this research provides essential data for rib support design.Khaled Mohamed Gamal Rashed Zorica Radakovic-Guzina 2020International Journal of Mining Science and Technology2020,30,1:4

6Impact of European Black Carbon on East Asian Summer Climate显示文摘The remote response of the East Asian summer monsoon(EASM)to European black carbon(EUBC)aerosols was studied by using an ensemble of sensitivity experiments with the Geophysical Fluid Dynamics Laboratory(GFDL)atmospheric general circulation model(AGCM)Atmospheric Model version 2.1(AM2.1).The results show that EUBC causes an enhanced EASM.The resulted enhanced southwesterly brings more moisture supply from the Bay of Bengal,which causes an increase in precipitation over the Yangtze River valley,northeastern China,the eastern part of the Yellow River valley,and the Tibetan Plateau.Diagnostic examination suggests that EUBC induces enhanced tropospheric heating over most of the Eurasian Continent through a propagating wave train and horizontal air temperature advection.This phenomenon results in intensified thermal contrast between land and ocean,which accounts for the enhanced EASM.Moreover,reductions in EUBC emission in 1992 may have contributed to decadal weakening of the EASM in the early 1990s.WAN Jiang-Hua Rashed MAHMOOD LI Shuanglin 2013Atmospheric and Oceanic Science Letters2013,6,5:4
7Modeled Influence of East Asian Black Carbon on Inter-Decadal Shifts in East China Summer Rainfall显示文摘Two inter-decadal shifts in East China summer rainfall during the last three decades of the 20th century have been identified.One shift occurred in the late 1970s and featured more rainfall in the Yangtze River valley and prolonged drought in North China.The other shift occurred in the early 1990s and featured increased rainfall in South China.The role of black carbon(BC) aerosol in the first shift event is controversial,and it has not been documented for the second event.In this study,the authors used Geophysical Fluid Dynamics Laboratory's(GFDL's) atmospheric general circulation model known as Atmosphere and Land Model(AM2.1) ,which has been shown to capture East Asian climate variability well,to investigate these issues by conducting sensitive experiments with or without historical BC in East Asia. The results suggest that the model reproduces the first shift well,including intensified rainfall in the Yangtze River and weakened monsoonal circulation.However,the model captures only a fraction of the observed variations for the second shift event.Thus,the role of BC in modulating the two shift events is different,and its impact is relatively less important for the early 1990s event.Rashed MAHMOOD LI Shuang-Lin 2011Atmospheric and Oceanic Science Letters2011,4,6:4
8Effect of aqueous extract of Solanum xanthocarpum Schrad. & Wendl. on postmenopausal syndrome in ovariectomized rats显示文摘OBJECTIVE: Solanum xanthocarpum Schrad. & Wendl.(Solanaceae) is present in many Ayurveda compound formulations including Chavanaprasha and Dasamoolarishta. The whole plant is used in conditions such as inflammation, constipation and promoting conception in females. In the present study, we carried out different tests to evaluate the effect of aqueous extract of Solanum xanthocarpum(SXE) in postmenopausal syndrome. METHODS: The study was carried out in bilaterally ovariectomized one-month-old Wistar rats(40–50 g). Bilaterally ovariectomized(OVX) Wistar rats were divided into four groups(n=6) receiving different treatments, consisting of a vehicle(distilled water), aqueous extract of Solanum xanthocarpum at two different doses(200 and 400 mg/kg) administered orally daily for 90 d and standard drug β estradiol at a dose of 1 mg/kg administered subcutaneously biweekly for 90 d. Estrogenic activity was assessed by vaginal cornifi cation, sexual behavior, serum estradiol and uterine weight to body weight ratio. Antiosteoporotic activity was assessed on the basis of biomechanical and biochemical parameters followed by histopathological studies, and antidepressant activity was assessed by forced swim test. RESULTS: SXE showed presence of steroids. At the dose of 200 mg/kg, it signifi cantly improved all the parameters of sexual behavior(P<0.01), caused vaginal cornifi cation, and increased serum estradiol and uterine weight(P<0.01). It also significantly improved all the parameters of bone strength as well as depression(P<0.01). Histopathology of bones confi rmed the above fi ndings. CONCLUSION: The study indicated that SXE may provide an effective treatment in the prevention of postmenopausal symptoms.Urmila Aswar Mayuri Gurav Ganesh More Khaled Rashed Manoj Aswar 2014Journal of Integrative Medicine2014,12,5:3
9Change of the mode of failure by interface friction and width-to-height ratio of coal specimens显示文摘Bumps in coal mines have been recognized as a major hazard for many years. These sudden and violent failures around mine openings have compromised safety, ventilation and access to mine workings.Previous studies showed that the violence of coal specimen failure depends on both the interface friction and width-to-height(W/H) ratio of coal specimen. The mode of failure for a uniaxially loaded coal specimen or a coal pillar is a combination of both shear failure along the interface and compressive failure in the coal. The shear failure along the interface triggered the compressive failure in coal. The compressive failure of a coal specimen or a coal pillar can be controlled by changing its W/H ratio. As the W/H ratio increases, the ultimate strength increases. Hence, with a proper combination of interface friction and the W/H ratio of pillar or coal specimen, the mode of failure will change from sudden violent failure which is brittle failure to non-violent failure which is ductile failure. The main objective of this paper is to determine at what W/H ratio and interface friction the mode of failure changes from violent to non-violent. In this research, coal specimens of W/H ratio ranging from 1 to 10 were uniaxially tested under two interface frictions of 0.1 and 0.25, and the results are presented and discussed.Gamal Rashed Syd S.Peng 2015Journal of Rock Mechanics and Geotechnical Engineering2015,7,3:3
10Effect of mesenchymal stem cells on anti-Thy1,1 induced kidney injury in albino rats显示文摘Objective:To evaluate the effect of mesenchymal stem cells(MSCs)in rats with anti-Thy 1,1nephritis.Methods:Female albino rats were divided into three groups,control group,anti-Thy 1,1group and treatment with i.v.MSCs group.MSCs were derived from bone marrow of male albino rats,Y—chromosome gene was detected by polymerase chain reaction in the kidney.Serum urea and creatinine were estimated for all groups.Kidney of all studied groups was examined histologically and histochemically(total carbohydrates and total proteins).DNA fragmentation and expression ofα-SMA were delected.Results:Kidney of animals injected with anti-Thy 1,1showed inflammatory leucocytic infiltration,hypertrophied glomeruli,tubular necrosis and congestion in the renal blood vessels.The kidney tissue also showed reduction of carbohydrates and total proteins together with increase in apoptosis and in expression ofα-SMA.Moreover,the levels of urea and creatinine were elevated.Treating animals with MSCs revealed that kidney tissue displayed an improvement in the histological and histochemical changes.Apoptosis andα-SMA expression were decreased,and the levels of urea and creatinine decreased.Conclusions:The obtained results demonstrated the potential of MSCs to ameliorate the structure and function of the kidney in rats with anti-Thy 1,1 nephritis possibly through the release of paracrine growth factor(s).Saber Sakr Laila Rashed Waheba Zarouk Rania El-Shamy 2013Asian Pacific Journal of Tropical Biomedicine2013,3,3:3
11Causes of recurring drought patterns in Xinjiang, China显示文摘Xinjiang Uygur Autonomous Region of China, with its unique topography and geographical location receives very less precipitation in summer as compared with other parts of China. The region is a land locked where moisture is supplied only by westerly winds from Atlantic Ocean as the moisture coming from Indian Ocean is mostly blocked by the Himalayas Range and the Tibetan plateau. In such a scenario, Xinjiang faces severe drought conditions offering significant challenges to water management. In this paper, we analyzed the drought periods in Xinjiang and discussed the various factors that might have influenced precipitation over the past forty-four years. For this purpose, we defined three periods of consecutive four years for high and low precipitation intensities. The average observed precipitation was 1.05 mm/day and 0.7 mm/day in summer (June-July-August) for the Tianshan Mountain region and Junggar Basin of Xinjiang, respectively. The drought conditions indicated that high sea level pressure, wind divergence and low convection were the prominent features that caused the droughts, which often do not allow the condensation process to coagulate the tiny water droplets into relatively large raindrops reducing the amount of precipitation in the region. The period of 1983-1986 is the lowest precipitation interval indicating the severe drought in the western Xinjiang (i.e western Tianshan Mountain region), for which, less moisture availability, strong divergence and less convection could be the most influencing factors.Rashed MAHMOOD Babar KHAN 2010Journal of Arid Land2010,2,4:3

13Effects of Sialic Acid from Edible Bird Nest on Cell Viability Associated with Brain Cognitive Performance in Mice显示文摘Background:Edible bird nest(EBN)is a natural food product rich in glycoprotein such as sialic acid,which has been reported to improve brain functions.The EBN is widely consumed due to its higher nutritional contents and antioxidant status;however,an interaction of EBN on brain cell metabolic activity and viability are still unclear.Objective:The objectives of this study were to identify the effect of sialic acid from EBN on the cell viability and to determine the appropriate concentration of sialic acid on cognitive performance in mice.Materials and Methods:The viability of pheochromocytoma and neuroblastoma cell lines were tested using the 3-[4,5-dimethylthiazol-2-yl]-2,5-diphenyltetrazolium bromide assay.For in vivo study,7-week-old female BALB/c mice were randomly assigned into four treatment groups and were treated with sialic acid for 21 days.At day 22,all mice were tested on cognitive performance by Y-maze test.Results:Treatment concentration of sialic acid extract and sialic acid standard at 60μg/mL(0.6 ppm)increased cell viability and showed no cytotoxicity effects in pheochromocytoma and neuroblastoma cell lines.In addition,an administration of higher dose of sialic acid at 0.6 ppm in animals improved Y-maze test performance,which they showed significantly higher number of entries and time spent in the novel arm.Conclusion:Thus,the current study shows that the sialic acid extract at 0.6 ppm improved brain cognitive performance in mice associated with an increased viability of pheochromocytoma and neuroblastoma cell lines.Siti Khadijah Abdul Khalid Aswir Abd Rashed Saleha Abdul Aziz Hafandi Ahmad 2019World Journal of Traditional Chinese Medicine2019,5,4:3

15Low-density lipoprotein receptor genetic polymorphism in chronic hepatitis C virus Egyptian patients affects treatment response显示文摘AIM: To correlate a genetic polymorphism of the low-density lipoprotein(LDL) receptor with antiviral responses in Egyptian chronic hepatitis C virus(HCV) patients.METHODS: Our study included 657 HCV-infected patients with genotype 4 who received interferonbased combination therapy. Patients were divided into two groups based on their response to therapy: 356 were responders, and 301 were non-responders. Patients were compared to 160 healthy controls. All patients and controls underwent a thorough physical examination, measurement of body mass index(BMI) and the following laboratory tests: serum alanine aminotransferase, aspartate aminotransferase, alkaline phosphatase, albumin, total bilirubin, direct bilirubin, prothrombin time, prothrombin concentration, INR, complete blood count, serum creatinine, fasting blood sugar, HCV antibody, and hepatitis B surface antigen. All HCV patients were further subjected to the following laboratory tests: HCV-RNA using quantitative polymerase chain reaction(PCR), antinuclear antibodies, thyroid-stimulating hormone, an LDL receptor(LDLR) genotype study of LDLR exon8 c.1171G>A and exon-10 c.1413G>A using real-time PCR-based assays, abdominal ultrasonography, ultrasonographic-guided liver biopsy, and histopathological examination of liver biopsies. Correlations of LDL receptor polymorphisms with HAI, METAVIR score, presence of steatosis, and BMI were performed in all cases.RESULTS: There were no statistically significant differences in response rates between the different types of interferon used or LDLR exon10 c.1413G>A. However, there was a significant difference in the frequency of the LDL receptor exon8 c.1171G>A genotype between cases(AA: 25.9%, GA: 22.2%, GG: 51.9%) and controls(AA: 3.8%, GA: 53.1% and GG: 43.1%)(P < 0.001). There was a statistically significant difference in the frequency of the LDLR exon 8C:1171 G>A polymorphism between responders(AA: 3.6%, GA: 15.2%, GG: 81.2%) and nonresponders(AA: 52.2%, GA: 30.6%, GG: 17.2%)(P < 0.001). The G allele of LDL receptor exon8 c.1171G>A predominated in cases and controls over the A allele, and a statistically significant association with response to interferon was observed. The frequency of the LDLR exon8 c.1171G>A allele in non-responders was: A: 67.4% and G: 32.6 vs A: 11.2% and G: 88.8% in responders(P < 0.001). Therefore, carriers of the A allele exhibited a 16.4 times greater risk for nonresponse. There was a significant association between LDL receptors exon8 c.1171G>A and HAI(P < 0.011). There was a significant association between LDL receptors exon8 c.1171G>A and BMI. The mean BMI level was highest in patients carrying the AA genotype(28.7 ± 4.7 kg/m2) followed by the GA genotype(28.1 ± 4.8 kg/m2). The lowest BMI was the GG genotype(26.6 ± 4.3 kg/m2)(P < 0.001). The only significant associations were found between LDL receptors exon8 c.1171G>A and METAVIR score or steatosis(P < 0.001).CONCLUSION: LDL receptor gene polymorphisms play a role in the treatment response of HCV and the modulation of disease progression in Egyptiansinfected with chronic HCV.Mazen Naga Mona Amin Dina Algendy Ahmed Elbadry May Fawzi Ayman Foda Serag Esmat Dina Sabry Laila Rashed Samia Gabal Manal Kamal 2015World Journal of Gastroenterology2015,21,39:2
16Tuning the metal filling fraction in metal-insulator-metal ultra-broadband perfect absorbers to maximize the absorption bandwidth显示文摘In this paper, we propose a methodology to maximize the absorption bandwidth of a metal-insulator-metal(MIM) based absorber. The proposed structure is made of a Cr-Al_2O_3-Cr multilayer design. At the initial step,the optimum MIM planar design is fabricated and optically characterized. The results show absorption above 0.9 from 400 nm to 850 nm. Afterward, the transfer matrix method is used to find the optimal condition for the perfect light absorption in an ultra-broadband frequency range. This modeling approach predicts that changing the filling fraction of the top Cr layer can extend light absorption toward longer wavelengths. We experimentally proved that the use of proper top Cr thickness and annealing temperature leads to a nearly perfect light absorption from 400 nm to 1150 nm, which is much broader than that of a planar design. Therefore, while keeping the overall process lithography-free, the absorption functionality of the design can be significantly improved. The results presented here can serve as a beacon for future performance-enhanced multilayer designs where a simple fabrication step can boost the overall device response without changing its overall thickness and fabrication simplicity.AMIR GHOBADI HODJAT HAJIAN ALIREZA RAHIMI RASHED BAYRAM BUTUN EKMEL OZBAY 2018Photonics Research2018,6,3:2
17Geochemistry of lamprophyres associated with uranium mineralization, Southeastern Desert, Egypt显示文摘Two brecciated shear zones (NNW-SSE) are found crosscutting cataclastic rocks. The cataclastic rocks (3.0 km2) occupy the core of the granitic pluton and enclose a roof pendant of mafic-ultramafic rocks. The NNW-SSE-extending lamprophyre dykes vary in thickness from 0.5 m to 1 m and up to 800 m long, cutting the cataclastic rocks and are composed mainly of plagioclases, amphiboles, relics of pyroxenes and K-feldspar phenocrysts embedded in fine-grained groundmass. They are characterized as being peraluminous, calc-alkaline in composition (chemical trap) and enriched in calcite, sulfide and P2O5. The lamprophyres were affected by hydrothermal alteration (chlorite-carbonate alteration) while the cataclastic rocks were affected by diagenetic alteration (K-feldspar-albite alteration). Uranium mineralization is the product of hydrothermal events and has been investigated by X-ray diffraction (XRD) and environmental scanning electron microscopy (ESEM), involving primary uranium minerals (U3O8) and secondary uranium minerals (uranophane and beta-uranophane, kasolite, torbernite, autonite and meta-autonite) in addition to U- bearing minerals (astrocyanite, betafite and fergusonite). The presence of different mineral parageneses associated with clay minerals indicates that the lamprophyres were subjected to acidic and alkaline mineralizing solutions. Moreover, the U-Zr/U, U-Ce/U values show negative correlations, confirming U-enrichment in both cataclastic rocks and shear zones while the Th-eU/eTh, Th-Zr/Th and Th-Ce/Th values show negative correlations, indicating that the U-bearing solutions are rich in Th in the cataclastic rocks only.Mohamed E.
