3Efficacy of topical chamomile on the incidence of phlebitis due to an amiodarone infusion in coronary care patients:a double-blind,randomized controlled trial显示文摘BACKGROUND:Amiodarone is a useful antiarrhythmic drug.Phlebitis,caused by intravenous amiodarone,is common in patients in coronary care units(CCUs).OBJECTIVE:The aim of this study was to evaluate the effect of topical chamomile on the incidence of phlebitis due to the administration of an amiodarone infusion into the peripheral vein.DESIGN,SETTING,PARTICIPANTS AND INTERVENTIONS:This was a randomized,double-blind clinical trial,conducted on 40 patients(n=20 per group)in two groups—an intervention group(chamomile ointment)and a control group(lanoline,as a placebo),hospitalized in the CCUs and undergoing an amiodarone infusion into the peripheral vein over 24 h.Following the cannulation and commencement of the infusion,placebo or chamomile ointment was rubbed in,up to 10 cm superior to the catheter and repeated every eight hours for three days.The cannula site was then assessed based on the phlebitis checklist.MAIN OUTCOME MEASURES:The incidence and time of occurrence of phlebitis,relative risk,severity of phlebitis were the main outcome measures.RESULTS:Nineteen patients(19/20)in the control group had phlebitis on the first day of the study and one patient(20/20)on the second day.In the intervention group,phlebitis occurred in 13 cases(13/20)on the first day and another two(2/7)was found on the second day.The incidence of phlebitis was significantly different between two groups(P=0.023).The cumulative incidence of phlebitis in the intervention group(15/20)is significantly later and lower than that in the control group(20/20)during two days(P=0.008).Two patients in the intervention group did not develop phlebitis at all during the 3-day study.Also,the relative risk of phlebitis in the two groups was 0.68(P=0.008 5).A significant difference was not observed with regard to phlebitis severity in both groups.CONCLUSION:It seems that phlebitis occurred to a lesser extent and at a later time frame in the intervention group compared to control group.Topical chamomile may be effective in decreasing the incidence of phlebitis due to an amiodarone infusion.Maryam Sharifi-Ardani Leili Yekefallah Saeed Asefzadeh Marjan Nassiri-Asl 2017Journal of Integrative Medicine2017,15,5:9
4EUS mini probes in diagnosis of cystic dystrophy of duodenal wall in heterotopic pancreas:A case report显示文摘Cystic dystrophy of the duodenal wall is a rare condition characterized by the development of cysts in heterotopic pancreatic tissue localized in the duodenal wall. A 38-year-old man was admitted to the hospital for abdominal pain and vomiting after food intake. The diagnosis of acute pancreatitis was initially suspected. Abdominal ultrasound examination revealed thickening of the second portion of duodenal wall within which, small cysts (diameter, less than 1 cm) were present in the vicinity of pancreatic head.The head of pancreas appeared enlarged (63 mm×42 mm)and hypoechoic. Upper endoscopy and barium X-ray series were performed revealing a severe circumferential deformation, as well as 4 cm long stenosis of the second portion of the duodenum. CT examination revealed multiple cysts located in an enlarged, thickened duodenal wall with moderate to strong post-contrast enhancement. We suspected that patient had cystic dystrophy of duodenal wall developed in the heterotopic pancreas and diagnosis was confirmed by endoscopic ultrasound (EUS). Endoscopi cutrasound (EUS) revealed drcular stenosis from the duodenal bulb onwards. A twenty megaHertz mini-probe examination further showed diffuse (intramural) infiltration of duodenal wall limited to the submucosa and muscularis propria of the second portion of duodenum with multiple microcysts within the thickened mucosa and submucosa, a. Patient was successfully surgically treated and pancreatoduodenectomy was performed. The pathological examination confirmed a diagnosis of cystic dystrophy of a heterotopic pancreas.Endoscopic ultrasonography features allow preoperative diagnosis of cystic dystrophy of a heterotopic pancreas in duodenal wall, with inb'alumina120 MHz mini probe sonography being more efficient in cases of luminal stenosis.Ivan Jovanovic Srbislav Knezevic Miodrag Krstic Marjan Micev 2004World Journal of Gastroenterology2004,10,17:8
5Helicobacter pylori antibiotic resistance in Iran显示文摘AIM: To examine the frequency of antibiotic resistance in Iranian Helicobacter pylori(H pylori) strains isolated from two major hospitals in Tehran.METHODS: Examination of antibiotic resistance was performed on 120 strains by modified disc diffusion test and PCR-RFLP methods. In addition, in order to identify the possible causes of the therapeutic failure in Iran, we also determined the resistance of these strains to the most commonly used antibiotics (metronidazole, amoxicillin,and tetracycline) by modified disc diffusion test.RESULTS: According to modified disc diffusion test, 1.6% of the studied strains were resistant to amoxicillin, 16.7% to clarithromycin, 57.5% to metronidazole, and there was no resistance to tetracycline. Of the clarithromycin resistant strains, 73.68% had the A2143G mutation in the 23S rRNA gene, 21.05% A2142C, and 5.26% A2142G.None of the sensitive strains were positive for any of the three point mutations. Of the metronidazole resistant strains, deletion in rdxA gene was studied and detected in only 6 (5%) of the antibiogram-based resistant strains.None of the metronidazole sensitive strains possessed rdxA gene deletion.CONCLUSION: These data show that despite the fact that clarithromycin has not yet been introduced to the Iranian drug market as a generic drug, nearly 20% rate of resistance alerts toward the frequency of macrolide resistance strains, which may be due to the widespread prescription of erythromycin in Iran. rdxA gene inactivation,if present in Iranian H pylori strains, may be due to other genetic defects rather than gene deletion.Marjan Mohammadi Delaram Doroud Nazanin Mohajerani Sadegh Massarrat 2005World Journal of Gastroenterology2005,11,38:8
6大荨麻提取物对高胆固醇血症大鼠血脂的影响(英文)显示文摘目的:探讨大荨麻提取物对高胆固醇血症大鼠血脂的影响。方法:雄性大鼠口服高胆固醇饮食(10mL/kg)4周,制备高胆固醇血症大鼠模型。造模同时灌服100、300mg/kg大荨麻提取物或10mg/kg洛伐他汀。观察大荨麻提取物对大鼠血脂、肝功能和肝脏病理的影响。结果:100、300mg/kg大荨麻提取物可以明显减少高胆固醇血症大鼠血总胆固醇和低密度脂蛋白胆固醇含量,并可以降低丙氨酸氨基转移酶(alanine aminotransferase,ALT)和天冬氨酸氨基转移酶(aspartate aminotransferase,AST)活性。苏木精和伊红染色显示,100mg/kg大荨麻提取物组肝脏组织未见明显脂肪变性,细胞形态与对照组相似;300mg/kg大荨麻提取物组肝脏组织可见到中等程度的脂肪变性。结论:大荨麻提取物可能通过降低血浆胆固醇含量和血浆ALT、AST活性治疗大鼠高胆固醇血症。Marjan NASSIRI-ASL Farzaneh ZAMANSOLTANI Esmail ABBASI Mohammad-Mehdi DANESHI Amir-Abdollah ZANGIVAND 2009中西医结合学报2009,7,5:7
7纳米流体在各种热管中的应用综述(英文)显示文摘纳米技术被广泛应用于传热装置中,以提高热性能。纳米流体应用于热管中,可降低热管的热阻,提高热管的传热能力。文中,对纳米在流体热管中的应用进行了全面的综述。阐述了纳米流体对传统热管、脉动热管、热虹膜等各种类型热管的热性能的影响。此外,发现了纳米颗粒的高效利用必须有一定的浓度;因动力黏度的增加导致颗粒团聚的可能性越高,高浓度的纳米颗粒会产生较高的热阻。热传递性能的增强是晶核位置的增多和纳米流体本身具有的更大热导率的结果。Mohammad Alhuyi NAZARI Mohammad H.

8Systematic mechanism-orientated approach to chronic pancreatitis pain显示文摘Pain in chronic pancreatitis(CP) shows similarities with other visceral pain syndromes(i.e.,inflammatory bowel disease and esophagitis),which should thus be managed in a similar fashion.Typical causes of CP pain include increased intrapancreatic pressure,pancreatic inflammation and pancreatic/extrapancreatic complications.Unfortunately,CP pain continues to be a major clinical challenge.It is recognized that ongoing pain may induce altered central pain processing,e.g.,central sensitization or pro-nociceptive pain modulation.When this is present conventional pain treatment targeting the nociceptive focus,e.g.,opioid analgesia or surgical/endoscopic intervention,often fails even if technically successful.If central nervous system pain processing is altered,specific treatment targeting these changes should be instituted(e.g.,gabapentinoids,ketamine or tricyclic antidepressants).Suitable tools are now available to make altered central processing visible,including quantitative sensory testing,electroencephalograpy and(functional) magnetic resonance imaging.These techniques are potentially clinically useful diagnostic tools to analyze central pain processing and thus define optimum management approaches for pain in CP and other visceral pain syndromes.The present review proposes a systematic mechanism-orientated approach to pain management in CP based on a holistic view of the mechanisms involved.Future research should address the circumstances under which central nervous system pain processing changes in CP,and how this is influenced by ongoing nociceptive input and therapies.Thus we hope to predict which patients are at risk for developing chronic pain or not responding to therapy,leading to improved treatment of chronic pain in CP and other visceral pain disorders.Stefan AW Bouwense Marjan de Vries Luuk TW Schreuder Soren S Olesen Jens B Frokjær Asbjorn M Drewes Harry van Goor Oliver HG Wilder-Smith 2015World Journal of Gastroenterology2015,21,1:6
9Cystic lymphangioma of the pancreas显示文摘Lymphangioma of the pancreas is an extremely rare benign tumour of lymphatic origin,with fewer than 60 published cases. Histologically,it is polycystic,with the cysts separated by thin septa and lined with endothelial cells. Though congenital,it can affect all age groups,and occurs more frequently in females. Patients usually present with epigastric pain and an associated palpable mass. Complete excision is curative,even though,depending on the tumour location,surgery may be simple or involve extensive pancreatic resection and anastomoses. The authors present a 49-year-old woman in whom a polycystic septated mass,35 mm x 35 mm in size,was discovered by ultrasonography (US) in the body of the pancreas during investigations for epigastric pain and nausea. At surgery,a well circumscribed polycystic tumor was completely excised,with preservation of the pancreatic duct. The postoperative recovery was uneventful. Histology confirmed a microcystic lymphangioma of the pancreas. Immunohistochemistry showed cystic endothelial cells reactivity to factor Ⅷ -RA (++),CD31 (+++) and CD34 (-). Postoperatively,abdominal pain disappeared and the patient remained symptomfree for 12 mo until now. Although extremely rare,lymphangioma of the pancreas should be taken into consideration as a differential diagnosis of a pancreatic cystic lesion,especially in women.Radoje B Colovic Nikica M Grubor Marjan T Micev Henry Dushan E Atkinson Vitomir I Rankovic Mihajlo M Jagodic 2008World Journal of Gastroenterology2008,14,44:6

11柔性高灵敏单壁碳纳米管气体传感器研究显示文摘在柔性聚对二甲苯C基底上制作了基于单壁碳纳米管的小型化、高灵敏、反应快速的气体传感器。使用介质电泳集成碳管束,并利用单链脱氧核糖核酸修饰增强器件灵敏度。当传感器暴露在甲醇蒸气中时,会出现明显可重复的反应,它可以检测含量低至4.3×10-6的甲醇,并且在相当宽的体积分数范围有清晰的分辨能力。对于4.3×10-6的含量,未修饰的传感器对应电阻变化率是4.8%;经过脱氧核糖核酸修饰,电阻变化率增加到了12.3%。此外,该传感器还显示了很快的响应速度和很好的测试复验性。研究表明:这种柔性气体传感器在未来环境监测应用中有很好的前景。李兴辉 Selvarasah Selvapraba LIU Yu Mohebbi Marjan Dokmeci Mehmet R 2011传感器与微系统2011,30,7:5
12Assessment of metal pollution in the Anzali Wetland sediments using chemical partitioning method and pollution indices显示文摘Metal pollution in aquatic ecosystems is of immense importance. Under various environment circumstances, the metal contents of sediments can enter into the overlying water body leading to severe toxicity. This study aims to determine metal concentrations in sediments of Anzali International Wetland in Iran. Chemical partitioning method is used to determine the portion of anthropogenic pollution and the mobility potential of each metal. The intensity of metal pollution in sediments of the wetland is assessed using three reliable indices. The results of chemical partitioning reveal that cadmium bear the highest risk of being released into the aquatic environment and high amount of manganese in sulfide bond phase implies the initiation of redox state in aquatic environment of the Anzali Wetland. The results of chemical partitioning studies show that Pb, Cd, Mn and As have the highest anthropogenic portion. Cluster analysis also confirms the results of chemical partitioning and indicates that the mentioned metals can be originated from anthropogenic sources. Sediment pollution indices, including, I_geo,I_POLL, and m-ERM-Q reveal that metals are in the range of low to moderate pollution and also show that the highest metal pollution is in the eastern and central parts of the wetland. This can be ascribed to rivers which are the recipient of industrial, agricultural and municipal wastewaters and flow into these parts of the wetland.ESMAEILZADEH Marjan KARBASSI Abdolreza MOATTAR Faramarz 2016Acta Oceanologica Sinica2016,35,10:4

14Hepatitis B virus genotypes in southwest Iran: Molecular, serological and clinical outcomes显示文摘AIM: To investigate the associations of hepatitis B virus (HBV) genotype with HBeAg and anti-HBe status, alanine aminotransferase (ALT) levels and HBV-DNA detection in different groups of HBV-infected patients in southwest Iran. METHODS: A total of 89 HBsAg-positive serum samples were collected from the same number of patients. All sera were then investigated to determine HBV DNA and serological markers. For all the polymerase chain reaction (PCR)-positive samples, biochemical, histopathological assays and genotyping were also performed. RESULTS: Genotype D was the only type of HBV foundin different clinical forms of acute and chronic infections. There was a high prevalence of HBeAg-negative HBV- infected patients with chronic hepatitis (52.7%). Out of 55 patients with chronic hepatitis, seven (12.7%) were diagnosed with cirrhosis. A significant association between the presence of anti-HBe antibody and an increase in ALT level, among either HBeAg-negative (P = 0.01) or HBeAg-positive (P = 0.026) patients, was demonstrated. No significant differences were observed between the clinical outcomes of HBeAg-positive and -negative individuals (P = 0.24). CONCLUSION: Genotype D has been recognized as the only type of HBV found in different clinical forms of HBV infections, including cirrhosis, among the residents of southwest Iran. Anti-HBe possibly plays a role in disease progression in some patients with chronic hepatitis, at least for a period of disease.Anahita Mojiri Abbas Behzad-Behbahani Mehdei Saberifirozi Maryam Ardabili Mahmood Beheshti Marjan Rahsaz Mehrdad Banihashemi Negar Azarpira Bita Geramizadeh Baharak Khadang Afsaneh Moaddeb Mojgan Ghaedi Tahereh Heidari Ardeshir Torab Alireza Salah Saeid Amirzadeh Zahra Jowkar Davood Mehrabani Samad Amini-Bavil-Olyaee Mohammad Ali Dehyadegari 2008World Journal of Gastroenterology2008,14,10:4
15Effect of sedative agent selection on morbidity, mortality and length of stay in patients with increase in intracranial pressure显示文摘BACKGROUND: To identify the effects of sedative agent selection on morbidity, mortality, and length of stay in patients with suspected increase in intracranial pressure. Recent trends and developments have resulted in changes to medications that were previously utilized as pharmacological adjuncts in the sedation and intubation of patients with suspected increases in intracranial pressure. Medications that were previously considered contraindicated are now being used with increasing regularity without demonstrated safety and effectiveness. The primary objective of this study is to evaluate and compare the use of Ketamine as an induction agent for patients with increased intracranial pressure. The secondary objective was to evaluate and compare the use of Etomidate, Midazolam, and Ketamine in patients with increased intracranial pressure. METHODS: We conducted a retrospective chart review of patients transported to our facility with evidence of intracranial hypertension that were intubated before trauma center arrival. Patients were identifi ed during a 22-month period from January 2014 to October 2015. Goals were to evaluate the impact of sedative agent selection on morbidity, mortality, and length of stay.RESULTS: During the review 148 patients were identifi ed as meeting inclusion criteria, 52 were excluded due to incomplete data. Of those the patients primarily received; Etomidate, Ketamine, and Midazolam. Patients in the Ketamine group were found to have a lower mortality rate after injury stratifi cation. CONCLUSION: Patients with intracranial hypertension should not be excluded from receiving Ketamine during intubation out of concern for worsening outcomes.Brian G.Cornelius Elizabeth Webb Angela Cornelius Kenneth W.G.Smith Srdan Ristic Jay Jain Urska Cvek Marjan Trutschl 2018World Journal of Emergency Medicine2018,9,4:4
16Evaluation of Calendula officinalis L.(marigold)flower as a natural growth promoter in comparison with an antibiotic growth promoter on growth performance,carcass traits and humoral immune responses of broilers显示文摘The objective of this experiment was to investigate the effects of dried powder of Calendula ojficinalis L.(marigold)flower as an antibiotic growth promoter substitute on growth performance,organ weights,and immunological parameters in broilers.A total of 240 mixed sex broilers(Ross 308)at 1 d of age were individually weighed and randomly assigned to 4 treatments with 4 replicates of 15 birds for 6 wk.The dietary treatments were:1)a basal diet(control);2)control plus 4.5 mg flavophospholipol/kg of diet;3)control plus 5 g marigold/kg of diet;4)control plus 10 g marigold/kg of diet.Antibody responses against Newcastle(NDV),influenza(AI)viruses,and sheep red blood cells(SRBC)were measured.Supplementing 4.5 mg flavophospholipol/kg of diet enhanced body weight(BW)of broilers at 14 and 28 d of age(P<0.05),but final BW at 42 d was not markedly affected.At 14 and 28 d of age,broilers fed diets supplemented with 10 g marigold/kg of diet had significantly lower BW compared with broilers fed the basal diet supplemented with antibiotic or 5 g marigold/kg of diet.During the starter period,broilers fed diets supplemented with antibiotic had significantly(P<0.05)better FCR compared with broilers supplemented with 10 g marigold/kg of diet,but did not differ from broilers fed the basal diet or basal diet supplemented with 5 g marigold/kg of diet.There were no significant differences in FCR between treatments,during grower,finisher phases as well as for the whole experiment.Carcass yield was significantly(P<0.05)higher in broilers supplemented with 5 g marigold/kg of diet compared with broilers in other groups.The treatments failed to induce any marked effect on immune parameters.In conclusion,the results of this experiment showed that supplementation of 5 and 10 g dried powder of marigold/kg of diet has no affirmative influence on growth performance of broilers.Marjan Foroutankhah Majid Toghyani Nasir LANDy 2019Animal Nutrition2019,,3:3

18Use of ginger versus stretching exercises for the treatment of primary dysmenorrhea: a randomized controlled trial显示文摘BACKGROUND: Dysmenorrhea is a common gynecologic problem. In some cases, non-medical treatments are considered to be more effective, with fewer side effects. Ginger and exercise are alternative treatments for dysmenorrhea, but in the present study they were not combined. OBJECTIVE: In this study, the effects of ginger and exercise on primary dysmenorrhea were compared.DESIGN, SETTING, PARTICIPANTS AND INTERVENTIONS: This randomized controlled trial was performed in Mazandaran University of Medical Sciences, Iran. Two groups of female students were recruited by simple random allocation. In each group, 61 students with moderate to severe primary dysmenorrhea with regular menstrual cycles and without a history of regular exercise were assessed. The ginger group received 250 mg ginger capsules from the onset of menstruation. In the exercise group, belly and pelvic stretching exercises were performed for 10 min, 3 times per week. MAIN OUTCOME MEASURES: Intensity of pain was assessed according to a visual analogue scale after the first and the second month. RESULTS: Exercise was significantly more effective than ginger for pain relief(31.57 ± 16.03 vs 38.19 ± 20.47, P = 0.02), severity of dysmenorrhea(63.9% vs 44.3% mild dysmenorrhea, P = 0.02) and decrease in menstrual duration(6.08 ± 1.22 vs 6.67 ± 1.24, P = 0.006), in the second cycle. CONCLUSION: Stretching exercises, as a safe and low-cost treatment, are more effective than ginger for pain relief in primary dysmenorrhea.TRIAL REGISTRATION: The trial was registered in www.IRCT.ir with No. 201203118822N2.Marjan Ahmad Shirvani Narges Motahari-Tabari Abbas Alipour 2017Journal of Integrative Medicine2017,15,4:3
19In-vitro bioactivity evaluation and physical properties of an epoxy-based dental sealer reinforced with synthesized fluorine-substituted hydroxyapatite, hydroxyapatite and bioactive glass nanofillers显示文摘The purpose of this study was to evaluate the physical properties and bioactivity potential of epoxy-based dental sealers modified with synthesized bioactive glass(BAG),hydroxyapatite(HA)and fluorine substituted hydroxyapatite(FHA)nanoparticles.The synthesized powders were incorporated at 10%and 20%into the epoxy-based dental sealer.The setting time,flow and solubility and microhardness of the modified and unmodified samples were examined.The bioactivity was evaluated using FESEM-EDX and elemental mapping,ATR-FTIR and XRD.The flow value of all of the experimental groups except the FHA modified samples,was greater than 20 mm.Concerning solubility,no specimens exhibited more than 1%weight loss.The solubility value of the FHA groups was statistically significant lower than other groups(p≤0.001).The mean hardness values of all of the modified samples were significantly higher than the unmodified group(p≤0.001).Regarding bioactivity,in vitro study revealed that after 3 days immersion in SBF a compact and continuous calcium phosphate layer formed on the surface of epoxy sealers containing BAG and HA nanoparticles.Based on these results,the addition of BAG and HA nanoparticles did not adversely alter the physical properties of epoxy sealers.Additionally,they improved the in vitro bioactivity of the epoxy sealer.Bahaa Abdulrazzaq Jerri Al-Bakhsh Farhad Shafiei Atieh Hashemian Kiana Shekofteh Behnam Bolhari Marjan Behroozibakhsh 2019Bioactive Materials2019,4,1:3
20Interference-Aware Multipath Routing Protocol for QoS Improvement in Event-Driven Wireless Sensor Networks显示文摘The existing multipath routing protocols for wireless sensor networks demonstrate the efficacy of traffic distribution over multiple paths to fulfill the Quality of Service (QoS) requirements of different applications.However,the performance of these protocols is highly affected by the characteristics of the wireless channel and may be even inferior to the performance of single-path approaches.Specifically,when multiple adjacent paths are being used concurrently,the broadcast nature of wireless channels results in inter-path interference which significantly degrades end-to-end throughput.In this paper,we propose a Low-Interference Energy-efficient Multipath Routing protocol (LIEMRO) to improve the QoS requirements of event-driven applications.In addition,in order to optimize resource utilization over the established paths,LIEMRO employs a quality-based load balancing algorithm to regulate the amount of traffic injected into the paths.The performance gain of LIEMRO compared to the ETX-based single-path routing protocol is 85%,80%,and 25% in terms of data delivery ratio,end-to-end throughput,and network lifetime,respectively.Furthermore,the end-to-end latency is improved more than 60%.Marjan Radi Behnam Dezfouli Kamalrulnizam Abu Bakar Shukor Abd Razak Mohammad Ali Nematbakhsh 2011Tsinghua Science and Technology2011,16,5:3
