1Relationship between hepatitis C virus infection and type 2 diabetes mellitus:Meta-analysis显示文摘AIM:To investigate the association between hepatitis C infection and type 2 diabetes mellitus.METHODS:Observational studies assessing the relationship between hepatitis C infection and type 2 diabetes mellitus were identified via electronic and hand searches.Studies published between 1988 to March 2011 were screened,according to the inclusion criteria set for the present analysis.Authors performed separate analyses for the comparisons between hepatitis C virus(HCV) infected and not infected,and HCV infected and hepatitis B virus infected.The included studies were further subgrouped according to the study design.Heterogenity was assessed using I2 statistics.The summary odds ratios with their corresponding 95% CIs were calculated based on a random-effects model.The included studies were subgrouped according to the study design.To assess any factor that could potentially affect the outcome,results were further stratified by age group(proportion of ≥ 40 years),gender(proportion of male gender),body mass index(BMI)(pro-portion of BMI ≥ 27),and family history of diabetes(i.e.,self reported).For stability of results,a sensitivity analysis was conducted including only prospective studies.RESULTS:Combining the electronic database and hand searches,a total of 35 observational studies(in 31 articles) were identified for the final analysis.Based on random-effects model,17 studies(n = 286 084) compared hepatitis C-infected patients with those who were uninfected [summary odds ratio(OR):1.68,95% CI:1.15-2.45].Of these 17 studies,7 were both a cross-sectional design(41.2%) and cohort design(41.2%),while 3 were case-control studies(17.6%).Nineteen studies(n = 51 156) compared hepatitis C-infected participants with hepatitis B-infected(summary OR:1.92,95% CI:1.41-2.62).Of these 19 studies,4(21.1%),6(31.6%) and 9(47.4%) were cross-sectional,cohort and case-control studies,respectively.A sensitivity analysis with 3 prospective studies indicated that hepatitis C-infected patients had a higher risk of developing type 2 diabetes compared with uninfected controls(summary odds ratio:1.41,95% CI:1.17-1.7;I2 = 0%).Among hepatitis C-infected patients,male patients(OR:1.26,95% CI:1.03-1.54) with age over 40 years(summary OR:7.39,95% CI:3.82-9.38) had an increased frequency of type 2 diabetes.Some caution must be taken in the interpretation of these results because there may be unmeasured confounding factors which may introduce bias.CONCLUSION:The findings support the association between hepatitis C infection and type 2 diabetes mellitus.The direction of association remains to be determined,however.Prospective studies with adequate sample sizes are recommended.Cho Naing Joon Wah Mak Syed Imran Ahmed Mala Maung 2012World Journal of Gastroenterology2012,18,14:12
2Seedling-lump integrated non-destructive monitoring for automatic transplanting with Intel RealSense depth camera显示文摘Non-destructive plant growth parameters measurement is an important concern in automatic-seedling transplanting.Recently,several image-basedmonitoring approaches have been proposed and potentially developed for several agricultural applications.The presented study proposed and developed a RealSense-based machine vision system for the close-shot seedling-lump integrated monitoring.The strategy was based on the close-shot depth information.Further,the point cloud clustering and suitable algorithms were applied to obtain the segmentation of 3D seedling models.In addition,the data processing pipeline was developed to assess the differentmorphological parameter of 4 different seedling varieties.The experiments were carried out with 4 different seedling varieties(pepper,tomato,cucumber,and lettuce)and trained under different light conditions(light and dark).Moreover,analysis results showed that therewas not significantly different(p<0.05)found towards light and dark environments due to close-shot near-infrared detection.However,the results revealed that the stem diameter relationship between RealSense and the manual method was found for R^2=0.68 cucumber,R^2=0.54 tomato,R^2=0.35 pepper,and R^2=0.58 lettuce seedlings.Whereas,the seedling height relationship between RealSense and the manual methodwas found higher than R^2=0.99,0.99,0.99,and 0.99 for pepper,tomato,cucumber,and lettuce,respectively.Based on the experiment results,it was concluded that the RGB-D integrated monitoring system with the purposed method could be practiced for nursery seedlings most promisingly without high labour requirements in terms of ease of use.The system revealed a good sturdiness and relevance for plant growth monitoring.Additionally,it has the perspective for future practical value to real-time vision servo operations for transplanting robots.Tabinda Naz Syed Liu Jizhan Zhou Xin Zhao Shengyi Yuan Yan Sami Hassan Ahmed Mohamed Imran Ali Lakhiar 2019Artificial Intelligence in Agriculture2019,,3:4
3Physicochemical characteristics of various milk samples available in Pakistan显示文摘We report physicochemical characteristics of various kinds of liquid milk commercially available in Pakistan in comparison with those of fresh natural milk from animals. Milk samples were collected from local markets at Peshawar, Pakistan, and analyzed for their physical features, including moisture, total solids, specific gravity, conductivity, viscosity and titratable acidity (lactic acid equivalent), and chemical components and macro-minerals, including total protein, casein, lactose, ash and minerals (Na, K and Mg). These items were compared with the physicochemical characteristics of the fresh natural milk samples from buffalo, cow and goat. The results were also compared with reported nutritional quality of milk from various countries and World Health Organization (WHO) standards. We found that all the physical features and chemical components of commercially available milk in Pakistan markets meet WHO's requirements, except for Na, K, Ca and Mg, which are below the standards.Mohammad IMRAN Hamayun KHAN Syed Shah HASSAN Rasool KHAN 2008Journal of Zhejiang University-Science B(Biomedicine & Biotechnology)2008,9,7:4
4Herding behavior in Ramadan and financial crises: the case of the Pakistani stock market显示文摘This study examines herding behavior in the Pakistani Stock Market under different market conditions,focusing on the Ramadan effect and Crisis period by using data from 2004 to 2014.Two regression models of Christie and Huang(Financ Analysts J 51:31-37,1995)and Chang et al.,(J Bank Finance 24:1651-1679,2000)are used for herding estimations.Results based on daily stock data reveal that there is an absence of herding behavior during rising(up)and falling(down)market as well as during high and low volatility in market.While herding behavior is detected during low trading volume days.Yearly analysis shows that herding existed during 2005,2006 and 2007,while it is not evident during rest of the period.However,herding behavior is not detected during Ramadan.Furthermore,during financial crisis of 2007-08,Pakistani Stock Market exhibits herding behavior due to higher uncertainty and information asymmetry.Imran Yousaf Shoaib Ali Syed Zulfiqar Ali Shah 2018Financial Innovation2018,4,1:2

13Impact of temperature on yield and related traits in cotton genotypes显示文摘Cotton growth and development is influenced by various uncontrollable environmental conditions. Temperature variations in the field can be created by planting at different dates. The objective of the present study was to evaluate the effect of planting dates and thermal temperatures(growing degree days) on yield of 4 cotton genotypes, viz., CIM-598, CIM-599, CIM-602 and Ali Akbar-703. Plants were subjected to 6 planting dates during 2013 and 2014 in a trial conducted in randomized complete block design with four replications. For boll number, boll weight and seed cotton yield, cotton genotypes exhibited significant differences, CIM-599 produced the highest seed cotton yield of 2 062 kg ha^(–1) on account of maximum boll number and boll weight. The highest seed cotton yield was recorded in planting dates from 15 th April to 1st May whereas early and delayed planting reduced the yield due to less accumulation of heat units. Regression analysis revealed that increase of one unit(15 days) from early to optimum date(15th March to 15 th April) increased yield by 93.58 kg ha^(–1). Delay in planting also decreased the seed cotton yield with the same ratio. Thus it is concluded that cotton must be sown from 15 th April to 1st May to have good productivity in this kind of environment.Kalim Ullah Niamatullah Khan Zahid Usman Rehmat Ullah Fazal Yazdan Saleem Syed Asif Imran Shah Muhammad Salman 2016Journal of Integrative Agriculture2016,15,3:1

19Single-atom catalysts for electrochemical N_(2)reduction to NH_(3)显示文摘The increasing demand for clean energy and growing concerns regarding environmental sustainability have led to greater attention devoted toward the production of clean fuels via green chemistry.In this respect,ammonia is a green alternative to fossil fuels and can serve as a clean energy source.There is now great interest in realizing the electrochemical reduction in atmospheric nitrogen(N_(2))for cheap,environmentally friendly and reliable ammonia(NH_(3))production worldwide.However,the robustness of the triple bond in N2 and the low efficiency of candidate catalysts limit the utility of this conversion.Single atom catalysts have been found to be more effective than nanoparticles due to their unique properties,and thus have been studied extensively for the nitrogen reduction reaction.In this review,we have covered the recent advances in design and synthesis of noble metal and non-noble metal single atom catalysts for the electrochemical reduction in nitrogen during the years 2018-2022.The catalyst efficiencies,with reference to coordination preferences and theoretical studies have been discussed.Moreover,we also provide insights into the current challenges and some considerations for further future studies.Muhammad Saqlain lqbal Zhi-Bo Yao Yu-Kun Ruan Ramsha Iftikhar Lei-Duan Hao Alex WRobertson Syed Muhammad Imran Zhen-Yu Sun 2023Rare Metals2023,42,4:1
