| 1 | Amino acids and mammary gland development:nutritional implications for milk production and neonatal growth显示文摘Milk is synthesized by mammary epithelial cel s of lactating mammals. The synthetic capacity of the mammary gland depends largely on the number and efficiency of functional mammary epithelial cel s. Structural development of the mammary gland occurs during fetal growth, prepubertal and post-pubertal periods, pregnancy, and lactation under the control of various hormones(particularly estrogen, growth hormone, insulin-like growth factor-I, progesterone, placental lactogen, and prolactin) in a species- and stage-dependent manner. Milk is essential for the growth, development, and health of neonates. Amino acids(AA), present in both free and peptide-bound forms, are the most abundant organic nutrients in the milk of farm animals. Uptake of AA from the arterial blood of the lactating dam is the ultimate source of proteins(primarily β-casein and α-lactalbumin) and bioactive nitrogenous metabolites in milk. Results of recent studies indicate extensive catabolism of branched-chain AA(leucine, isoleucine and valine) and arginine to synthesize glutamate,glutamine, alanine, aspartate, asparagine, proline, and polyamines. The formation of polypeptides from AA is regulated not only by hormones(e.g., prolactin, insulin and glucocorticoids) and the rate of blood flow across the lactating mammary gland, but also by concentrations of AA, lipids, glucose, vitamins and minerals in the maternal plasma, as well as the activation of the mechanistic(mammalian) target rapamycin signaling by certain AA(e.g.,arginine, branched-chain AA, and glutamine). Knowledge of AA utilization(including metabolism) by mammary epithelial cells will enhance our fundamental understanding of lactation biology and has important implications for improving the efficiency of livestock production worldwide. | Reza Rezaei Zhenlong Wu Yongqing Hou Fuller W.Bazer Guoyao Wu | 2016 | Journal of Animal Science and Biotechnology2016，7，4： | 36 |
| 2 | Biochemical and physiological bases for utilization of dietary amino acids by young Pigs显示文摘Protein is quantitatively the most expensive nutrient in swine diets. Hence it is imperative to understand the physiological roles played by amino acids in growth, development, lactation, reproduction, and health of pigs to improve their protein nutrition and reduce the costs of pork production. Due to incomplete knowledge of amino acid biochemistry and nutrition, it was traditionally assumed that neonatal, post-weaning, growing-finishing, and gestating pigs could synthesize sufficient amounts of all 'nutritionally nonessential amino acids' (NEAA) to support maximum production performance. Therefore, over the past 50 years, much emphasis has been placed on dietary requirements of nutritionally essential amino acids as building blocks for tissue proteins. However, a large body of literature shows that NEAA, particularly glutamine, glutamate, arginine and proline regulate physiological functions via cell signaling pathways, such as mammalian target of rapamycin, AMP-activated protein kinase, extracellular signal-related kinase, Jun kinase, mitogen-activated protein kinase, and NEAA-derived gaseous molecules (e.g., nitric oxide, carbon monoxide, and hydrogen sulfide). Available evidence shows that under current feeding programs, only 70% and 55% of dietary amino acids are deposited as tissue proteins in 14-day-old sow-reared piglets and in 30-day-old pigs weaned at 21 days of age, respectively. Therefore, there is an urgent need to understand the roles and dietary requirements of NEAA in swine nutrition. This review highlights the basic biochemistry and physiology of absorption and utilization of amino acids in young pigs to enhance the efficacy of utilization of dietary protein and to minimize excretion of nitrogenous wastes from the body. | Reza Rezaei Weiwei Wang Zhenlong Wu Zhaolai Dai Junjun Wang Guoyao Wu | 2013 | Journal of Animal Science and Biotechnology2013，4，2： | 22 |
| 3 | Risk assessment of the emergency processes: Healthcare failure mode and effect analysis显示文摘BACKGROUND: Ensuring about the patient's safety is the f irst vital step in improving the quality of care and the emergency ward is known as a high-risk area in treatment health care. The present study was conducted to evaluate the selected risk processes of emergency surgery department of a treatment-educational Qaem center in Mashhad by using analysis method of the conditions and failure effects in health care.METHODS: In this study, in combination(qualitative action research and quantitative crosssectional), failure modes and effects of 5 high-risk procedures of the emergency surgery department were identified and analyzed according to Healthcare Failure Mode and Effects Analysis(HFMEA). To classify the failure modes from the 'nursing errors in clinical management model(NECM)', the classification of the effective causes of error from 'Eindhoven model' and determination of the strategies to improve from the 'theory of solving problem by an inventive method' were used. To analyze the quantitative data of descriptive statistics(total points) and to analyze the qualitative data, content analysis and agreement of comments of the members were used.RESULTS: In 5 selected processes by 'voting method using rating', 23 steps, 61 sub-processes and 217 potential failure modes were identifi ed by HFMEA. 25(11.5%) failure modes as the high risk errors were detected and transferred to the decision tree. The most and the least failure modes were placed in the categories of care errors(54.7%) and knowledge and skill(9.5%), respectively. Also, 29.4% of preventive measures were in the category of human resource management strategy.CONCLUSION: 'Revision and re-engineering of processes', 'continuous monitoring of the works', 'preparation and revision of operating procedures and policies', 'developing the criteria for evaluating the performance of the personnel', 'designing a suitable educational content for needs of employee', 'training patients', 'reducing the workload and power shortage', 'improving team communication' and 'preventive management of equipment's' were on the agenda as the guidelines. | Yasamin Molavi Taleghani Fatemeh Rezaei Hojat Sheikhbardsiri | 2016 | World Journal of Emergency Medicine2016，7，2： | 15 |
| 4 | Hepatitis B and C virus-induced hepatitis: Apoptosis, autophagy, and unfolded protein response显示文摘AIM: To investigate the co-incidence of apoptosis, autophagy, and unfolded protein response(UPR) in hepatitis B(HBV) and C(HCV) infected hepatocytes.METHODS: We performed immunofluorescence confocal microscopy on 10 liver biopsies from HBV and HCV patients and tissue microarrays of HBV positive liver samples. We used specific antibodies for LC3β, cleaved caspase-3, BIP(GRP78), and XBP1 to detect autophagy, apoptosis and UPR, respectively. AntiHCV NS3 and anti-HBs antibodies were also used to confirm infection. We performed triple blind counting of events to determine the co-incidence of autophagy(LC3β punctuate), apoptosis(cleaved caspase-3), and unfolded protein response(GRP78) with HBV and HCV infection in hepatocytes. All statistical analyses were performed using SPSS software for Windows(Version 16 SPSS Inc, Chicago, IL, United States). P-values < 0.05 were considered statistically significant. Statistical analyses were performed with Mann-Whitney test to compare incidence rates for autophagy, apoptosis, and UPR in HBV- and HCV-infected cells and adjacent noninfected cells.RESULTS: Our results showed that infection of hepatocytes with either HBV and HCV induces significant increase(P < 0.001) in apoptosis(cleavage of caspase-3), autophagy(LC3β punctate), and UPR(increase in GRP78 expression) in the HCV- and HBVinfected cells, as compared to non-infected cells of the same biopsy sections. Our tissue microarray immunohistochemical expression analysis of LC3β in HBV^(Neg) and HBV^(Pos) revealed that majority of HBVinfected hepatocytes display strong positive stainingfor LC3β. Interestingly, although XBP splicing in HBVinfected cells was significantly higher(P < 0.05), our analyses show a slight increase of XBP splicing was in HCV-infected cells(P > 0.05). Furthermore, our evaluation of patients with HBV and HCV infection based on stage and grade of the liver diseases revealed no correlation between these pathological findings and induction of apoptosis, autophagy, and UPR.CONCLUSION: The results of this study indicate that HCV and HBV infection activates apoptosis, autophagy and UPR, but slightly differently by each virus. Further studies are warranted to elucidate the interconnections between these pathways in relation to pathology of HCV and HBV in the liver tissue. | Behzad Yeganeh Adel Rezaei Moghadam Javad Alizadeh Emilia Wiechec Seyed Moayed Alavian Mohammad Hashemi Bita Geramizadeh Afshin Samali Kamran Bagheri Lankarani Martin Post Payam Peymani Kevin M Coombs Saeid Ghavami | 2015 | World Journal of Gastroenterology2015，21，47： | 13 |

| 6 | Preparation of nanocrystalline γ-Al_2O_3 catalyst using different procedures for methanol dehydration to dimethyl ether显示文摘A series of nanocrystalline γ-alumina are synthesized by different procedures, namely, thermal decomposition method (sample A), precipita-tion method (sample B) and sol-gel method using sucrose and hexadecyltrimethyl ammonium bromide (CTAB) as templates (samples C and D, respectively). Textural and acidic properties of γ-alumina samples are characterized by XRD, N2 adsorption-desorption and NH3-TPD techniques. Vapor-phase dehydration of methanol into dimethyl ether is carried out over these samples. Among them, sample C shows the highest catalytic activity. NH3-TPD analysis reveals that the sample with smaller crystallite size possesses higher concentration of medium acidic sites and consequently higher catalytic activity. Thermal decomposition method leads to decrease in both surface area and moderate acidity, therefore it is the cause of lower catalytic activity. | Ahmad Reza Keshavarz Mehran Rezaei Fereydoon Yaripour | 2011 | Journal of Natural Gas Chemistry2011，20，3： | 7 |
| 7 | 25-gauge transconjunctival diagnostic vitrectomy in suspected cases of intraocular lymphoma: a case series and review of the literature显示文摘AIM:To report the cytology results of 25-gauge transconjunctival(25G-TSV)diagnostic vitrectomy in cases suspicious for intraocular lymphoma(IOL),and compare the results to those reported in the literature.METHODS:Clinical and cytopathological records of 18vitreous biopsy specimens obtained via 25G-TSV diagnostic vitrectomy in 12 patients suspicious for IOL were reviewed retrospectively.A review of the literature in regards to the diagnostic yields of vitreous specimens obtained via 25-gauge and 20-gauge diagnostic vitrectomy in suspected cases of IOL was performed.RESULTS:Eighteen eyes from 12 patients with clinical suspicion of IOL underwent diagnostic 25G-TSV.The cytopathological investigations demonstrated IOL in 15eyes(83.3%).Vitreous analysis was non-diagnostic in 3eyes(16.7%).CONCLUSION:Twenty-five-gauge diagnostic vitrectomy yields adequate sample for cytological evaluation of the vitreous in cases suspicious for IOL.The diagnostic results of the 25G-TSV in the current study are superior to those reported for 20-gauge vitrectomy but equivalent to those reported for 25G-TSV in the published literature. | Mozhgan Rezaei Kanavi Masoud Soheilian Sayed Bagher Hosseini Amir A.

| 8 | CO_2 reforming of methane over nickel catalysts supported on nanocrystalline MgAl_2O_4 with high surface area显示文摘In this paper dry reforming of methane (DRM) was carried out over nanocrystalline MgAl2O4-supported Ni catalysts with various Ni loadings. Nanocrystalline MgAl2O4 spinel with high specific surface area was synthesized by a co-precipitation method with the addition of pluronic P123 triblock copolymer as surfactant, and employed as catalyst support. The prepared samples were characterized by X-ray diffraction (XRD), N2 adsorption, H2 chemisorption, temperature-programmed reduction (TPR), temperature-programmed oxidation (TPO), temperature- programmed desorption (TPD) and transmission and scanning electron microscopies (TEM, SEM) techniques. The obtained results showed that the catalyst support has a nanocrystalline structure (crystal size: about 5 nm) with a high specific surface area (175 m2 g-1) and a mesoporous structure. Increasing in nickel content decreased the specific surface area and nickel dispersion. The prepared catalysts showed high catalytic activity and stability during the reaction. SEM analysis revealed that whisker type carbon deposited over the spent catalysts and increasing in nickel loading increased the amount of deposited carbon. The nickel catalyst with 7 wt% of nickel showed the highest catalytic activity. | Narges Hadian Mehran Rezaei Zeinab Mosayebi Fereshteh Meshkani | 2012 | Journal of Natural Gas Chemistry2012，21，2： | 6 |

| 11 | Development of a time-dependent energy model to calculate the mining-induced stress over gates and pillars显示文摘Generally, longwall mining-induced stress results from the stress relaxation due to destressed zone that occurs above the mined panel. Knowledge of induced stress is very important for accurate design of adjacent gateroads and intervening pillars which helps to raise the safety and productivity of longwall mining operations. This study presents a novel time-dependent analytical model for determination of the longwall mining-induced stress and investigates the coefficient of stress concentration over adjacent gates and pillars. The model is developed based on the strain energy balance in longwall mining incorporated to a rheological constitutive model of caved materials with time-varying parameters. The study site is the Tabas coal mine of Iran. In the proposed model, height of destressed zone above the mined panel, total longwall mining-induced stress, abutment angle, induced vertical stress, and coefficient of stress concentration over neighboring gates and intervening pillars are calculated. To evaluate the effect of proposed model parameters on the coefficient of stress concentration due to longwall mining, sensitivity analysis is performed based on the field data and experimental constants. Also, the results of the proposed model are compared with those of existing models. The comparative results confirm a good agreement between the proposed model and the in situ measurements. According to the obtained results, it is concluded that the proposed model can be successfully used to calculate the longwall mining-induced stress. Therefore, the optimum design of gate supports and pillar dimensions would be attainable which helps to increase the mining efficiency. | Mohammad Rezaei Mohammad Farouq Hossaini Abbas Majdi | 2015 | Journal of Rock Mechanics and Geotechnical Engineering2015，7，3： | 6 |
| 12 | Effect of Ni loadings on the activity and coke formation of MgO-modified Ni/Al_2O_3 nanocatalyst in dry reforming of methane显示文摘MgO-modified Ni/Al2O3 catalysts with different Ni loadings were prepared and employed in dry reforming of methane(DRM). The effect of Ni loadings on the activity and coke formation of Ni/MgO-Al2O3 catalysts were investigated. The synthesized catalysts were characterized by XRD, N2adsorption-desorption, SEM, TPO and TPR techniques. The obtained results showed that increasing nickel loading decreased the BET surface area and increased the catalytic activity and amount of deposited carbon. In addition, the effect of gas hourly space velocity(GHSV) and feed ratio were studied. | Zahra Alipour Mehran Rezaei Fereshteh Meshkani | 2014 | Journal of Energy Chemistry2014，23，5： | 6 |
| 13 | Prediction of representative deformation modulus of longwall panel roof rock strata using Mamdani fuzzy system显示文摘Deformation modulus is the important parameter in stability analysis of tunnels, dams and mining structures. In this paper, two predictive models including Mamdani fuzzy system(MFS) and multivariable regression analysis(MVRA) were developed to predict deformation modulus based on data obtained from dilatometer tests carried out in Bakhtiary dam site and additional data collected from longwall coal mines. Models inputs were considered to be rock quality designation, overburden height, weathering,unconfined compressive strength, bedding inclination to core axis, joint roughness coefficient and fill thickness. To control the models performance, calculating indices such as root mean square error(RMSE),variance account for(VAF) and determination coefficient(R2) were used. The MFS results show the significant prediction accuracy along with high performance compared to MVRA results. Finally, the sensitivity analysis of MFS results shows that the most and the least effective parameters on deformation modulus are weathering and overburden height, respectively. | Mohammad Rezaei Mostafa Asadizadeh Abbas Majdi Mohammad Farouq Hossaini | 2015 | International Journal of Mining Science and Technology2015，25，1： | 6 |
| 14 | Selective methanation of carbon monoxide in hydrogen rich stream over Ni/CeO_2 nanocatalysts显示文摘In the present work, selective methanation of carbon monoxide in hydrogen rich stream was investigated over Ni/CeO2 nanocatalysts. The obtained results revealed that increasing in nickel loading decreased the BET surface area, pore volume and nickel dispersion. The 25% Ni/CeO2 with a NiO crystal size of 12 nm exhibited the highest activity in CO methanation reaction and reached to maximum CO conversion and CH4 selectivity at temperatures above 230 ℃. The catalytic results revealed that CO selective methanation well progressed at lower temperatures while CO2 methanation was completely suppressed until CO conversion reached to maximum value. | Behzad Nematollahi Mehran Rezaei Ebrahim Nemati Lay | 2015 | Journal of Rare Earths2015，33，6： | 6 |

| 16 | Effects of CO_2 content on the activity and stability of nickel catalyst supported on mesoporous nanocrystalline zirconia显示文摘The effects of carbon dioxide content on the catalytic performance and coke formation of nickel catalyst sup- ported on mesoporous nanocrystalline zirconia with high surface area and pure tetragonal crystalline phase were investigated in methane reforming with carbon dioxide. The samples were characterized by XRD, BET, TPR, TPO, TPH, TEM, and SEM techniques. The catalyst prepared showed high surface area and a mesoporous structure with a narrow pore size distribution. The obtained results revealed that the increase in CO2 content increased the methane conversion and stability of the catalyst and significantly reduced the coke deposition. The TPH analysis showed that several species of carbon with different reactivities toward hydrogenation were deposited on the spent catalysts employed under different CO2 contents. | M. Rezaei S.M.

| 17 | 双眼屈光不正性弱视和远视的相关性研究(英文)显示文摘目的:探讨在远视、眼正位儿童中双眼屈光不正性弱视与远视患病率的关系。方法:选取56例两眼对称远视儿童,平均年龄5.5岁,分为两组,双眼远视≤+4.0D等效球镜组和双眼远视>+4.0D等效球镜组。评估两组双眼屈光不正性弱视的患病率,并进行比较。结果:在32例双眼远视≤+4.0D等效球镜组中,4例(13%)患双眼屈光不正性弱视;24例双眼远视>+4.0D等效球镜组中,15例(63%)患双眼屈光不正性弱视。统计学分析显示两组双眼屈光不正的儿童中弱视患病率有显著性差异(P<0.01)。结论:双眼屈光不正性弱视在双眼远视的儿童中并不罕见,尤其是当远视度数大于+4.0D等效球镜时。基于本次调查,双眼远视>+4.0D的儿童有13%~63%发展成两眼屈光不正性弱视。由此说明远视>+4.0D的儿童患两眼屈光不正性弱视的几率较大。 | Ali Rezaei Shokooh Farhad Adhami Moqadam Abdolhamid Najafi Youness Ghasemiy Mahnaz Vaezi MSc | 2012 | 国际眼科杂志2012，12，3： | 4 |
| 18 | Thermodynamic analysis of combined reforming process using Gibbs energy minimization method: In view of solid carbon formation显示文摘Thermodynamic analysis was applied to study combined partial oxidation and carbon dioxide reforming of methane in view of carbon formation. The equilibrium calculations employing the Gibbs energy minimization were performed upon wide ranges of pressure (1-25 atm), temperature (600-1300 K), carbon dioxide to methane ratio (0-2) and oxygen to methane ratio (0-1). The thermodynamic results were compared with the results obtained over a Ru supported catalyst. The results revealed that by increasing the reaction pressure methane conversion decreased. Also it was found that the atmospheric pressure is the preferable pressure for both dry reforming and partial oxidation of methane and increasing the temperature caused increases in both activity of carbon and conversion of methane. The results clearly showed that the addition of O 2 to the feed mixture could lead to a reduction of carbon deposition. | Behzad Nematollahi Mehran Rezaei Ebrahim Nemati Lay Majid Khajenoori | 2012 | Journal of Natural Gas Chemistry2012，21，6： | 4 |
| 19 | Assessments on emergy and greenhouse gas emissions of internal combustion engine automobiles and electric automobiles in the USA显示文摘Increasing energy consumption in the transportation sector results in challenging greenhouse gas(GHG)emissions and environmental problems.This paper involved integrated assessments on GHG emissions and emergy of the life cycle for the internal combustion engine(ICE)and electric automobiles in the USA over the entire assumed fifteen-year lifetime.The hotspots of GHG emissions as well as emergy indices for the major processes of automobile life cycle within the defined system boundaries have been investigated.The potential strategies for reducing GHG emissions and emergy in the life cycle of both ICE and electric automobiles were further proposed.Based on the current results,the total GHG emissions from the life cycle of ICE automobiles are 4.48 E+07 kg CO2-e which is320 times higher than that of the electric automobiles.The hotspot area of the GHG emissions from ICE and electric automobiles are operation phase and manufacturing process,respectively.Interesting results were observed that comparable total emergy of the ICE automobiles and electric automobiles have been calculated which were 1.54 E+17 and 2.20 E+17 sej,respectively.Analysis on emergy index evidenced a better environmental sustainability of electric automobiles than ICE automobiles over the life cycle due to its higher ESI.To the authors’knowledge,it is the first time to integrate the analysis of GHG emissions together with emergy in industrial area of automobile engineering.It is expected that the integration of emergy and GHG emissions analysis may provide a comprehensive perspective on eco-industrial sustainability of automobile engineering. | Ran Jing Chen Yuan Hamidreza Rezaei Jin Qian Zhen Zhang | 2020 | Journal of Environmental Sciences2020，32，4： | 4 |
| 20 | Enhanced Efficiency of Milk Utilization for Growth in Surviving Low-Birth-Weight Piglets显示文摘This study determined effects of birth weights (0.70 to 1.09, 1.10 to 1.49, 1.50 to 1.89, and≥1.90 kg) on the efficiency of milk utilization for growth in sow-reared piglets. One-hundred-sixty piglets from 18 multiparous sows (Landrace×Large White) were individually weighed immediately after birth (day 0) and at 7-day intervals for 35 days. Milk consumption of piglets was determined weekly using the weigh-suckle-weigh method. Deaths of piglets were recorded daily. Piglets with the lightest birth weight had the highest incidence of mortality. Birth weights between 0.70 and 1.89 kg were positively associated with average daily gains (ADG, g/day) during the suckling period (P<0.01). Compared with piglets having birth weights of 1.50 to 1.89 kg, birth weights≥1.90 kg did not confer any additional benefit on preweaning survival or ADG. Colostrum or milk consumption per kilogram of body weight among low-, normal-, and large-birth-weight piglets did not differ in the first week. At days 14 to 35, milk consumption of piglets (g/kg BW/day) increased (P<0.01) but the ratio of gain to milk consumption decreased (P<0.01) progressively, as their birth weights increased from 0.70 to ≥1.90 kg. Additionally, surviving low-birth-weight piglets had a higher relative growth rate (%/day) than normal-and large-birth-weight piglets. Based on these novel findings, it is imperative that great efforts be made to improve the survival of low-birth-weight piglets so as to increase the efficiency of nutrient utilization by both lactating sows and suckling piglets. | Reza Rezaei Darrell A.
