2Association of gene variants with susceptibility to type 2 diabetes among Omanis显示文摘AIM:To investigate the association of 10 known common gene variants with susceptibility to type 2diabetes mellitus(T2D)among Omanis.METHODS:Using case-control design,a total of992 diabetic patients and 294 normoglycemic Omani Arabs were genotyped,by an allelic discrimination assay-by-design TaqMan method on fast real time polymerase chain reaction system,for the following gene variants:KCNJ11(rs5219),TCF7L2(rs7903146),CDKAL1(rs10946398),CDKN2A/B(rs10811661),FTO(rs9939609 and rs8050136),IGF2BP2(rs4402960),SLC30A8(rs13266634)CAPN10(rs3792267)and HHEX(rs1111875).T2D patients were recruited from the Diabetes Clinic(n=243)and inpatients(n=749)at Sultan Qaboos Univesity Hospital(SQUH),Muscat,Oman.Adult control participants(n=294)were volunteers from the community and from those visiting Family Medicine Clinic at SQU,for regular medical checkup.The difficulty in recruiting Omani participants with no family history of diabetes was the main reason behind the small number of control participants in this study.Almost all volunteers questioned had a relativewith diabetes mellitus.Inspite of the small number of normoglycemic controls in this study,this sample was sufficient for detection of genes and loci for common alleles influencing T2D with an odds ratio of≥1.3reaching at least 80%power.Data was collected from June 2010 to February 2012.RESULTS:Using binary logistic regression analysis,four gene variants showed significant association with T2D risk:KCNJ11(rs5219,P=5.8×10^(-6),OR=1.74),TCF7L2(rs7903146,P=0.001,OR=1.46),CDKAL1(rs10946398,P=0.002,OR=1.44)and CDKN2A/B(rs10811661,P=0.020,OR=1.40).The fixation index analysis of these four gene variants indicated significant genetic differentiation between diabetics and controls{[KCNJ11(rs5219),P<0.001],[TCF7L2(rs7903146),P<0.001],[CDKAL1(rs10946398),P<0.05],[CDKN2A/B(rs10811661),P<0.05]}.The highest genotype variation%between diabetics and controls was found at KCNJ11(2.07%)and TCF7L2(1.62%).This study was not able to detect an association of T2D risk with gene variants of IGF2BP2(rs4402960),SLC30A8(rs13266634),CAPN10(rs3792267)and HHEX(rs1111875).Moreover,no association was found between FTO gene variants(rs9939609 and rs8050136)and T2D risk.However,T2D risk was found to be significantly associated with obesity(P=0.002,OR=2.22);and with the Waist-to-Hip ratio(n=532,P=1.9×10^(-7),OR=2.4),[among males(n=234,P=1.2×10^(-4),OR=2.0)and females(n=298,P=0.001,OR=6.3)].CONCLUSION:Results confirmed the association of KCNJ11(rs5219),TCF7L2(rs7903146),CDKAL1(rs10946398)and CDKN2A/B(rs10811661)gene variants with susceptibility to T2D among Omani Arabs.Sawsan Al-Sinani Nicolas Woodhouse Ali Al-Mamari Omaima Al-Shafie Mohammed Al-Shafaee Said Al-Yahyaee Mohammed Hassan Deepali Jaju Khamis Al-Hashmi Mohammed Al-Abri Khalid Al-Rassadi Syed Rizvi Yengo Loic Philippe Froguel Riad Bayoumi 2015World Journal of Diabetes2015,6,2:3
3Numerical investigation of variable viscosities and thermal stratification effects on MHD mixed convective heat and mass transfer past a porous wedge in the presence of a chemical reaction显示文摘An analysis is presented to investigate the effects of variable viscosities and thermal stratification on the MHD mixed convective heat and mass transfer of a viscous, incompressible, and electrically conducting fluid past a porous wedge in the presence of a chemical reaction. The wall of the wedge is embedded in a uniform non-Darcian porous medium in order to allow for possible fluid wall suction or injection. The governing boundary layer equations are written into a dimensionless form by similarity transformations. The transformed coupled nonlinear ordinary differential equations are solved numerically with finite difference methods. Numerical calculations up to the thirdorder level of truncation are carried out for different values of dimensionless parameters. The results are presented graphically, and show that the flow field and other quantities of physical interest are significantly influenced by these parameters. The results are compared with those available in literature, and show excellent agreement.I. Muhaimin R. Kandasamy Azme B. Khamis 2009Applied Mathematics and Mechanics(English Edition)2009,30,11:2
4Assessment of the Off-season Rainfall of January to February 2020 and Its Socio Economic Implications in Tanzania: A Case Study of the Northern Coast of Tanzania显示文摘This article examines the off season rainfall in northern coast Tanzania(NCT)including Zanzibar which occurred in January and February 2020(JF).Like the JF rainfalls of 2001,2004,2010,2016 and 2018,the JF(2020)rainfall was more unique in damages including loss of lives,properties and infrastructures.The study used the NCEP/NCAR reanalysis data to examine the cause of uniqueness of JF rainfall in 2001,2004,2010,2016,2018 and 2020 over NCT and Zanzibar.These datasets include monthly mean u,v wind at 850,700,500,and 200 mb;SSTs,mean sea level pressure(MSLP)anomalies,Dipole Mode Index(DMI),and monthly rainfall from NCT and Zanzibar stations.Datasets were processed and calculated into long term,seasonal,and monthly averages,indeed,Precipitation Index(PI)was calculated.Correlation analysis between the rainfall(December to January),SST,DMI and 850 mb wind vectors;and long-term percentage contribution of investigated parameters was calculated.Results revealed significant positive and negative correlations between JF rainfall,SSTs and DMI.Moreover,JFs of 2004 and 2016 had higher rainfalls of 443 mm with percentage contribution of up to 406%,while January and February,2020 had the highest of 269.1 and 101.1mm in Zanzibar and 295 and 146.1 mm over and NCT areas,with highest January long-term rainfall contribution of 356%in Zanzibar and 526%over NCT.The DJF(2019/20)had the highest rainfall record of 649.5 mm in Zanzibar contributing up to 286%,while JF 2000 rainfall had a good spatial and temporal distribution over most NCT areas.JF,2020 rainfall had impacts of more than 20 people died in Lindi and several infrastructures including Kiyegeya Bridge in Morogoro were damaged.Conclusively,more research works on understanding the dynamics of wet and dry JF seasons should be conducted.Kombo Hamad Kai Sarah E Osima Agnes Laurence Kijazi Mohammed Khamis Ngwali Asya Omar Hamad 2021Journal of Atmospheric Science Research2021,4,2:2
5High frequency multiscale relationships among major cryptocurrencies:portfolio management implications显示文摘This paper examines the high frequency multiscale relationships and nonlinear multiscale causality between Bitcoin,Ethereum,Monero,Dash,Ripple,and Litecoin.We apply nonlinear Granger causality and rolling window wavelet correlation(RWCC)to 15 min-data.Empirical RWCC results indicate mostly positive co-movements and long-term memory between the cryptocurrencies,especially between Bitcoin,Ethereum,and Monero.The nonlinear Granger causality tests reveal dual causation between most of the cryptocurrency pairs.We advance evidence to improve portfolio risk assessment,and hedging strategies.Walid Mensi Mobeen Ur Rehman Muhammad Shafiullah Khamis Hamed Al‑Yahyaee Ahmet Sensoy 2021Financial Innovation2021,7,1:2
