| 1 | Essential oils used in aromatherapy: A systemic review显示文摘Nowadays, use of alternative and complementary therapies with mainstream medicine has gained the momentum. Aromatherapy is one of the complementary therapies which use essential oils as the major therapeutic agents to treat several diseases. The essential or volatile oils are extracted from the flowers, barks, stem, leaves, roots, fruits and other parts of the plant by various methods. It came into existence after the scientists deciphered the antiseptic and skin permeability properties of essential oils. Inhalation, local application and baths are the major methods used in aromatherapy that utilize these oils to penetrate the human skin surface with marked aura. Once the oils are in the system, they remodulate themselves and work in a friendly manner at the site of malfunction or at the affected area. This type of therapy utilizes various permutation and combinations to get relief from numerous ailments like depression, indigestion, headache, insomnia, muscular pain, respiratory problems, skin ailments, swollen joints, urine associated complications etc. The essential oils are found to be more beneficial when other aspects of life and diet are given due consideration. This review explores the information available in the literature regarding therapeutic, medical, cosmetic, psychological, olfactory, massage aromatherapy, safety issues and different plants used in aromatherapy. All the available information was compiled from electronic databases such as Academic Journals, Ethnobotany, Google Scholar, PubM ed, Science Direct, Web of Science, and library search. | Babar Ali Naser Ali Al-Wabel Saiba Shams Aftab Ahamad Shah Alam Khan Firoz Anwar | 2015 | Asian Pacific Journal of Tropical Biomedicine2015，5，8： | 20 |
| 2 | Extraction and characterization of alumina nanopowders from aluminum dross by acid dissolution process显示文摘A significant amount of aluminum dross is available as a waste in foundry industries in Bangladesh. In this study, alumina was extracted from aluminum dross collected from two foundry industries situated in Dhamrai and Manikgang, near the capital city, Dhaka. Aluminum dross samples were found to approximately contain 75wt% Al2O3 and 12wt% SiO2. An acid dissolution process was used to recover the alumina value from the dross. The effects of various parameters, e.g., temperature, acid concentration, and leaching time, on the extraction of alumina were studied to optimize the dissolution process. First, Al(OH)3 was produced in the form of a gel. Calcination of the Al(OH)3 gel at 1000°C, 1200°C, and 1400°C for 2 h produced θ-Al2O3,(α+θ)-Al2O3, and α-alumina powder, respectively. Thermal characterization of the Al(OH)3 gel was performed by thermogravimetric/differential thermal analysis(TG/DTA) and differential scanning calorimetry(DSC). The phases and crystallite size of the alumina were determined by X-ray diffraction analysis. The dimensions of the alumina were found to be on the nano level. The chemical compositions of the aluminum dross and alumina were determined by X-ray fluorescence(XRF) spectroscopy. The microstructure and morphology of the alumina were studied with scanning electron microscopy. The purity of the alumina extracted in this study was found to be 99.0%. Thus, it is expected that the obtained alumina powders can be potentially utilized as biomaterials. | Saifur Rahman Sarker Zahangir Alam Rakibul Qadir M A Gafur Mohammad Moniruzzaman | 2015 | International Journal of Minerals,Metallurgy and Materials2015，22，4： | 20 |

| 6 | Acute-on-chronic liver failure:recent update显示文摘Acute on chronic liver failure(ACLF) was first described in 1995 as a clinical syndrome distinct to classic acute decompensation.Characterized by complications of decompensation,ACLF occurs on a background of chronic liver dysfunction and is associated with high rates of organ failure and significant short-term mortality estimated between45%and 90%.Despite the clinical relevance of the condition,it still remains largely undefined with continued disagreement regarding its precise etiological factors,clinical course,prognostic criteria and management pathways.It is concerning that,despite our relative lack of understanding of the condition,the burden of ACLF among cirrhotic patients remains significant with an estimated prevalence of 30.9%.This paper highlights our current understanding of ACLF,including its etiology,diagnostic and prognostic criteria and pathophysiology.It is evident that further refinement of the ACLF classification system is required in order to detect high-risk patients and improve short-term mortality rates.The field of metabolomics certainly warrants investigation to enhance diagnostic and prognostic parameters,while the use of granulocyte-colony stimulating factor is a promising future therapeutic intervention for patients with ACLF. | Azeem Alam Ka Chun Suen Daqing Ma | 2017 | The Journal of Biomedical Research2017，31，4： | 16 |
| 7 | Kinetic adsorption of application of carbon nanotubes for Pb(Ⅱ) removal from aqueous solution显示文摘The capability of carbon nanotubes (CNTs) to adsorb lead (Pb) in aqueous solution was investigated. Batch mode adsorption experiment was conducted to determine the effects of pH, agitation speed, CNTs dosage and contact time. The removal of Pb(Ⅱ) reached maximum value 85% or 83% at pH 5 or 40 mg/L of CNTs, respectively. Higher correlation coeffcients from Langmuir isotherm model indicates the strong adsorptions of Pb(Ⅱ) on the surface of CNTs (adsorption capacity Xm = 102.04 mg/g). The results indicates that the highest percentage removal of Pb (96.03%) can be achieved at pH 5, 40 mg/L of CNTs, contact time 80 min, and agitation speed 50 r/min. | Nassereldeen A Kabbashi Muataz A Atieh Abdullah Al-Mamun Mohamed E S Mirghami MD Z Alam Noorahayu Yahya | 2009 | Journal of Environmental Sciences2009，21，4： | 15 |
| 8 | Pyogenic liver abscess: Changing patterns in approach显示文摘AIM: To define optimum management of the pyogenic liver abscess and assess new trends in treatment. METHODS: One hundred and sixty nine patients with pyogenic liver abscess managed at Sher-i-Kashmir In- stitute of Medical Sciences, Srinagar, Kashmir (India) from July 2001 to August 2006 were studied to evaluate and define the optimum treatment. RESULTS: Mortality in the surgically treated group of patients was 9.4% (12/119), while those treated non-surgically had a fatality rate of 16.66% (7/42). Multiple liver abscesses treated surgically had a surprisingly low mortality of 30%. The biliary tract (64.97%) was the most common cause of liver abscess. Multiple abscesses, mixed organisms and abscess complications are all associated with a significantly increased mortality. However, the lethality of the primary disease process was the most important factor in determining survival.CONCLUSION: Transperitoneal surgical drainage and antibiotics are the mainstay of treatment. Percutaneous drainage is recommended for high risk patients only. | Ajaz A Malik Shams UL Bari Khawaja Abdul Rouf Khurshid Alam Wani | 2010 | World Journal of Gastrointestinal Surgery2010，2，12： | 15 |

| 12 | Insulin resistance in development and progression of nonalcoholic fatty liver disease显示文摘Although insulin resistance(IR)is strongly associated with nonalcoholic fatty liver disease(NAFLD),the association of IR and NAFLD is not universal and correlation between IR and severity of NAFLD is still controversial.In this review,we summarize recent evidence that partially dissociates insulin resistance from NAFLD.It has also been reported that single-nucleotide polymorphisms in the diacylglycerol acyltransferase gene,rather than IR,account for the variability in liver fat content.Polymorphisms of the patatin-like phospholipase 3 gene have also been reported to be associated with NAFLD without metabolic syndrome,which suggests that genetic conditions that promote the development of fatty changes in the liver may occur independently of IR.Moreover,environmental factors such as nutrition and physical activity as well as small intestinal bacterial overgrowth have been linked to the pathogenesis of NAFLD,although some of the data are conflicting.Therefore,findings from both genetically engineered animal models and humans with genetic conditions,as well as recent studies that have explored the role of environmental factors,have confirmed the view that NAFLD is a polygenic disease process caused by both genetic and environmental factors.Therefore,IR is not the sole predictor of the pathogenesis of NAFLD. | Shahinul Alam Golam Mustafa Mahabubul Alam Nooruddin Ahmad | 2016 | World Journal of Gastrointestinal Pathophysiology2016，7，2： | 12 |

| 18 | Landslide inventory and susceptibility modelling using geospatial tools,in Hunza-Nagar valley,northern Pakistan显示文摘A comprehensive landslide inventory and susceptibility maps are prerequisite for developing and implementing landslide mitigation strategies. Landslide susceptibility maps for the landslides prone regions in northern Pakistan are rarely available. The Hunza-Nagar valley in northern Pakistan is known for its frequent and devastating landslides. In this paper, we have developed a landslide inventory map for Hunza-Nagar valley by using the visual interpretation of the SPOT-5 satellite imagery and mapped a total of 172 landslides. The landslide inventory was subsequently divided into modelling and validation data sets. For the development of landslide susceptibility map seven discrete landslide causative factors were correlated with the landslide inventory map using weight of evidence and frequency ratio statistical models. Four different models of conditional independence were used for the selection of landslide causative factors. The produced landslides susceptibility maps were validated by the success rate and area under curves criteria. The prediction power of the models was also validated with the prediction rate curve. The validation results shows that the success rate curves of the weight of evidence and the frequency models are 82% and 79%, respectively. The prediction accuracy results obtained from this study are 84% for weight of evidence model and 80% for the frequency ratio model. Finally, the landslide susceptibility index maps were classified into five different varying susceptibility zones. The validation and prediction result indicates that the weight of evidence and frequency ratio model are reliable to produce an accurate landslide susceptibility map, which may be helpful for landslides management strategies. | Alam Sher BACHA Muhammad SHAFIQUE Harald van der WERFF | 2018 | Journal of Mountain Science2018，15，6： | 8 |
