1氧化铝对铁矿石烧结质量和生产率的影响(英文)显示文摘烧结矿是现代高炉生产的主要含铁原料。合理控制入炉烧结矿的理化性能与冶金性能对高炉生产和稳定操作是很必要的。铁矿粉是烧结矿的主要原料,其化学成分和烧结料层内的热量条件在烧结过程中起着重要的作用。化学成分等参数也决定着烧结矿矿相结构和质量。由于含氧化铝原料的低反应性及其液相的高粘性,因此在人们的预料中高铝矿石对烧结矿结构组成的影响并不好。烧结混合料中的氧化铝在同化过程中需要消耗大量热量,延迟烧结过程。在确保高炉渣的流动性方面,氧化铝也需要消耗较大热量。不论是烧结还是高炉的生产实绩均表明,氧化铝是有害的。一般而言,高含铁量与低脉石的印度矿与其他矿石的不同特点就是氧化铝含量高。由于高品味铁矿石的消耗殆尽,使用可利用的烧结原料成为生产必需。因此,必须要掌握氧化铝的作用及其对烧结矿质量和生产过程的影响。实验室完成了不同氧化铝含量水平(2.00%~5.46%)的实验,可从中了解氧化铝在烧结矿矿物学、生产率、物理性能和冶金性能方面的影响。随着烧结矿中氧化铝含量的增加,残存赤铁矿、复合铁酸钙(SFCA)和孔隙率增加,而磁铁矿和硅酸盐比例下降。烧结生产率和烧结矿转鼓强度(TI)随着氧化铝含量上升而下降,反映烧结矿冶金性能的诸如低温还原粉化率(RDI)和还原率(RI)提高。T Umadevi S Prakash U K Bandopadhyay P C Mahapatra M Prabhu Madhu Ranjan 2010世界钢铁2010,,1:4
2Carcinogenic Helicobacter pylori in gastric pre-cancer and cancer lesions: Association with tobacco-chewing显示文摘AIM:To investigate the low gastric cancer incidence rate relative to the highly prevalent Helicobacter pylori(H.pylori)infection;data relevant to H.pylori infection during gastric carcinogenesis in Indian patients is currently lacking.METHODS:The present study examines the prevalence of H.pylori infection in DNA derived from 156endoscopic gastric biopsies of different disease groups that represent gastric pre-cancer[intestinal metaplasia(n=15),dysplasia(n=15)],cancer[diffuse adenocarcinoma(n=44),intestinal adenocarcinoma(n=21)],and symptomatic but histopathologically-normal controls(n=61).This was done by generic ureC polymerase chain reaction(PCR)and cagA-specific PCR that could specifically identify the carcinogenic H.pylori strain.RESULTS:Our analysis showed the presence of H.pylori infection in 61%of symptomatic histopathologically-normal individuals,however only 34%of control tissues were harboring the cagA+H.pylori strain.A similar proportion of H.pylori infection(52%)and cagA(26%)positivity was observed in the tumor tissue of the gastric cancer group.In comparison,H.pylori infection(90%)and cagA positivity(73%)were the highest in gastric pre-cancer lesions.In relation to tobacco and alcohol abuse,H.pylori infection showed an association with tobacco chewing,whereas we did not observe any association between tobacco smoking or alcohol abuse with prevalence of H.pylori infection in the tissue of any of the patient groups studied.CONCLUSION:High incidence of H.pylori infection and carcinogenic cagA positive strain in pre-cancer lesions during gastric carcinogenesis may beArvind Pandey Satyendra Chandra Tripathi Sutapa Mahata Kanchan Vishnoi Shirish Shukla Sri Prakash Misra Vatsala Misra Suresh Hedau Ravi Mehrotra Manisha DwivediZ Alok C Bharti 2014World Journal of Gastroenterology2014,20,22:4
3Superior safety of direct oral anticoagulants compared to Warfarin in patients with atrial fibrillation and underlying cancer: a national veterans affairs database study显示文摘Background Studies evaluating safety of warfarin and direct oral anticoagulants(DOACs) for prevention of stroke in patients with atrial fibrillation(AF) are lacking. Methods & Results All patients(n = 196,521) receiving care at veteran’s affairs with active cancer and AF from 2010–2015 were included. One-year mortality was significantly higher in unadjusted analysis with warfarin(44.9%) compared to dabigatran(25%, P < 0.001), rivaroxaban(24.4%, P < 0.001) and apixaban(30%, P < 0.001) and after adjusting for age, sex and type of cancer mortality(OR = 2.66, 95% CI: 2.52–2.82, P < 0.001). Risk of ischemic stroke(13.5% vs. 11.1%, 12.0%, 14.0%) was similar, however risk of hemorrhagic stroke was significantly higher among patients receiving warfarin(1.2%) compared to patients receiving dabigatran(0.5%), rivaroxaban(0.7%) and apixaban(0.8%) respectively, P = 0.04. Conclusions We demonstrated the superior safety profile of DOACs compared to warfarin among patients with underlying cancer and AF. Warfarin was associated with higher mortality, similar ischemic stroke risk but higher risk of hemorrhagic stroke.Abhishek C Sawant Arnav Kumar Wilmon Mccray Sheldon Tetewsky Linda Parone Srilekha Sridhara Meghana Prakash Hiriyur Prakash Gary Tse Tong LIU Nidhi Kanwar Aishwarya Bhardwaj Sahoor Khan Christopher Manion Ankush Lahoti Ashish Pershad Peter Elkin John Corbelli 2019Journal of Geriatric Cardiology2019,16,9:2
4Comparative effectiveness of adipose-derived mesenchymal stromal cells in the management of knee osteoarthritis:A meta-analysis显示文摘BACKGROUND Osteoarthritis(OA)is the most common joint disorder,is associated with an increasing socioeconomic impact owing to the ageing population.AIM To analyze and compare the efficacy and safety of bone-marrow-derived mesenchymal stromal cells(BM-MSCs)and adipose tissue-derived MSCs(AD-MSCs)in knee OA management from published randomized controlled trials(RCTs).METHODS Independent and duplicate electronic database searches were performed,including PubMed,EMBASE,Web of Science,and Cochrane Library,until August 2021 for RCTs that analyzed the efficacy and safety of AD-MSCs and BM-MSCs in the management of knee OA.The visual analog scale(VAS)score for pain,Western Ontario McMaster Universities Osteoarthritis Index(WOMAC),Lysholm score,Tegner score,magnetic resonance observation of cartilage repair tissue score,knee osteoarthritis outcome score(KOOS),and adverse events were analyzed.Analysis was performed on the R-platform using OpenMeta(Analyst)software.Twenty-one studies,involving 936 patients,were included.Only one study compared the two MSC sources without patient randomization;hence,the results of all included studies from both sources were pooled,and a comparative critical analysis was performed.RESULTS At six months,both AD-MSCs and BM-MSCs showed significant VAS improvement(P=0.015,P=0.012);this was inconsistent at 1 year for BM-MSCs(P<0.001,P=0.539),and AD-MSCs outperformed BM-MSCs compared to controls in measures such as WOMAC(P<0.001,P=0.541),Lysholm scores(P=0.006;P=0.933),and KOOS(P=0.002;P=0.012).BM-MSC-related procedures caused significant adverse events(P=0.003)compared to AD-MSCs(P=0.673).CONCLUSION Adipose tissue is superior to bone marrow because of its safety and consistent efficacy in improving pain and functional outcomes.Future trials are urgently warranted to validate our findings and reach a consensus on the ideal source of MSCs for managing knee OA.Sathish Muthu Sandesh C Patil Naveen Jeyaraman Madhan Jeyaraman Prakash Gangadaran Ramya Lakshmi Rajendran Eun Jung Oh Manish Khanna Ho Yun Chung Byeong-Cheol Ahn 2023World Journal of Orthopedics2023,14,1:2
