2Persistent alanine aminotransferase elevation among the general Iranian population: Prevalence and causes显示文摘AIM: To determine the prevalence and causes of persistently elevated alanine aminotransferase (ALT) levels among the general population in northern Iran. METHODS: A total of 2292 (1376 female, aged 18-75 year), were selected by systematic clustered random sampling from the cities and villages of Gonbad and Kalaleh in Golestan Province and invited to participate in the study. A comprehensive history regarding alcohol drinking and medication was taken. Body mass index (BMI), viral markers and ALT levels were measured. If ALT level was ≥ 40 U/L, it was rechecked twice within 6 mo. Those with ≥ 2 times elevation of ALT were considered as having persistently elevated ALT level. Non-alcoholic fatty liver disease (NAFLD) was diagnosed based on evidence of fatty liver upon sonography and excluding other etiology. RESULTS: A total of 2049 (1351 female) patients participated in the study, 162 (7.9%) had elevated ALT level at the first measurement. Persistently elevated ALT level was detected in 64 (3.1%) participants, with51 (79.6%) with no obvious etiology, six (9.3%) with Hepatitis B, four (6.2%) with Hepatitis C virus (HCV) infection and three (4.6%) with alcoholic hepatitis. The prevalence of NAFLD and alcoholic hepatitis was 2.04% (42 patients) and 0.1% (three), respectively. There was correlation between NAFLD and male gender, overweight, diabetes and living in an urban area [odds ratio = 3.03 (95% CI: 1.6-5.72), 4.21 (95% CI: 1.83-9.68), 2.86 (95% CI: 1.05-7.79) and 2.04 (95% CI: 1.00-4.16) respectively]. CONCLUSION: NAFLD is the most common cause of persistently elevated serum ALT level among the general population of Iran.Raika Jamali Mahmoodreza Khonsari Shahin Merat Masoud Khoshnia Elham Jafari Alireza Bahram Kalhori Hassan Abolghasemi Sedighe Amini Mahtab Maghsoudlu Mohammad Reza Deyhim Houri Rezvan Akram Pourshams 2008World Journal of Gastroenterology2008,14,18:7
3Engineering Microneedle Patches for Improved Penetration:Analysis,Skin Models and Factors Affecting Needle Insertion显示文摘Transdermal microneedle(MN)patches are a promising tool used to transport a wide variety of active compounds into the skin.To serve as a substitute for common hypodermic needles,MNs must pierce the human stratum corneum(~10 to 20μm),without rupturing or bending during penetration.This ensures that the cargo is released at the predetermined place and time.Therefore,the ability of MN patches to sufficiently pierce the skin is a crucial requirement.In the current review,the pain signal and its management during application of MNs and typical hypodermic needles are presented and compared.This is followed by a discussion on mechanical analysis and skin models used for insertion tests before application to clinical practice.Factors that affect insertion(e.g.,geometry,material composition and cross-linking of MNs),along with recent advancements in developed strategies(e.g.,insertion responsive patches and 3D printed biomimetic MNs using two-photon lithography)to improve the skin penetration are highlighted to provide a backdrop for future research.Pooyan Makvandi Melissa Kirkby Aaron RJHutton Majid Shabani Cynthia K.Y.Yiu Zahra Baghbantaraghdari Rezvan Jamaledin Marco Carlotti Barbara Mazzolai Virgilio Mattoli Ryan F.Donnelly 2021Nano-Micro Letters2021,13,6:5
4Evaluation of rutting performance of stone matrix asphalt mixtures containing warm mix additives显示文摘Permanent deformation or rutting, one of the most important distresses in flexible pavements, has long been a problem in asphalt mixtures and thus a great deal of research has been focused on the development of a rheological parameter that would address the rutting susceptibility of both unmodified and modified bituminous binders. In this research, three warm mix additives(Sasobit, Rheofalt and Zycotherm) were used to modify 60-70 penetration grade base binder. The rutting potential of both modified and unmodified binders were evaluated through the multiple stress creep recovery(MSCR)-based parameter, nonrecoverable compliance(Jnr) and recovery parameter(R). Several performance tests carried on stone matrix asphalt(SMA) mixtures comprising different nominal maximum aggregate sizes(NMASs, 9.5, 12.5 and 19 mm), like Marshall stability, dynamic and static creep and Hamburg wheel tracking tests to evaluate their rutting performance. The objective of this work is to correlate MSCR test results to performance. Results indicate that for the range of the gradations investigated in this work, increasing the nominal maximum aggregate size of the gradation would increase the permanent deformation resistance of the SMA mixture. Addition of 3% sasobit to base binder leads an increase in Jnr100 about 82%. Addition of 2% rheofalt to base binder leads an recovery increase of about 9.76 % and 27.44% in stress levels of 100 and 3200 Pa, respectively. The results reveal that rutting resistance of mixtures improves as Jnr decreases. The use of the MSCR test in the rutting characterization of bituminous binders is highly recommended based on the results of this work.Rezvan Babagoli Hassan Ziari 2017Journal of Central South University2017,24,2:4
5Distinct element modelling of fracture plan control in continuum and jointed rock mass in presplitting method of surface mining显示文摘Controlled blasting techniques are used to control overbreak and to aid in the stability of the remaining rock formation. Presplitting is one of the most common methods which is used in many open pit mining and surface blast design. The purpose of presplitting is to form a fracture plane across which the radial cracks from the production blast cannot travel. The purpose of this study is to investigate of effect of presplitting on the generation of a smooth wall in continuum and jointed rock mass. The 2D distinct element code was used to simulate the presplitting in a rock slope. The blast load history as a function of time was applied to the inner wall of each blasthole. Important parameters that were considered in the analysis were stress tensor and fracturing pattern. The blast loading magnitude and blasthole spacing and jointing pattern were found to be very significant in the final results.Sharafisafa Mansour Aliabadian Zeinab Alizadeh Rezvan Mortazavi Ali 2014International Journal of Mining Science and Technology2014,24,6:4
