| 1 | One step synthesis of pyrido[1,2-a]benzimidazole derivatives of aryloxypyrazole and their antimicrobial evaluation显示文摘A new series of pyrido[1,2-α]benzimidazole derivatives bearing the aryloxypyrazole nucleus have been synthesized by base-catalyzed cyclocondensation reaction through multi-component reaction(MCR) approach.All the synthesized compounds were investigated against a representative panel of pathogenic strains using broth microdilution minimum inhibitory concentration(MIC) method for their in vitro antimicrobial activity.Reviewing the data,majority of the compounds were found to be active against employed pathogens.SAR study explores that antimicrobial activity is strongly depends on the nature of the substituents at the ether linked aryl ring attached to the pyrazole unit,together with the substituent present on the C_5 of the benzimidazole unit. | Hardik H.Jardosh Chetan B.Sangani Manish P.Patel Ranjan G.Patel | 2013 | Chinese Chemical Letters2013,24,2: | 9 |
| 2 | Use of three-dimensional printing in preoperative planning in orthopaedic trauma surgery: A systematic review and meta-analysis显示文摘BACKGROUND With the increasing complexity of surgical interventions performed in orthopaedic trauma surgery and the improving technologies used in threedimensional(3D)printing,there has been an increased interest in the concept.It has been shown that 3D models allow surgeons to better visualise anatomy,aid in planning and performing complex surgery.It is however not clear how best to utilise the technique and whether this results in better outcomes.AIM To evaluate the effect of 3D printing used in pre-operative planning in orthopaedic trauma surgery on clinical outcomes.METHODS We performed a comprehensive systematic review of the literature and a metaanalysis.Medline,Ovid and Embase were searched from inception to February 8,2018.Randomised controlled trials,case-control studies,cohort studies and case series of five patients or more were included across any area of orthopaedic trauma.The primary outcomes were operation time,intra-operative blood loss and fluoroscopy used.RESULTS Seventeen studies(922 patients)met our inclusion criteria and were reviewed.The use of 3D printing across all specialties in orthopaedic trauma surgery demonstrated an overall reduction in operation time of 19.85%[95%confidence intervals(CI):(-22.99,-16.71)],intra-operative blood loss of 25.73%[95%CI:(-31.07,-20.40)],and number of times fluoroscopy was used by 23.80%[95%CI:(-38.49,-9.10)].CONCLUSION Our results suggest that the use of 3D printing in pre-operative planning in orthopaedic trauma reduces operative time,intraoperative blood loss and the number of times fluoroscopy is used. | Catrin Morgan Chetan Khatri Sammy A Hanna Hutan Ashrafian Khaled M Sarraf | 2020 | World Journal of Orthopedics2020,11,1: | 7 |
| 3 | Current concepts in the management of recurrent anterior gleno-humeral joint instability with bone loss显示文摘The management of recurrent anterior gleno-humeral joint instability is challenging in the presence of boneloss.It is often seen in young athletic patients and dislocations related to epileptic seizures and may involve glenoid bone deficiency,humeral bone deficiency or combined bipolar lesions.It is critical to accurately identify and assess the amount and position of bone loss in order to select the most appropriate treatment and reduce the risk of recurrent instability after surgery.The current literature suggests that coracoid and iliac crest bone block transfers are reliable for treating glenoid defects.The treatment of humeral defects is more controversial,however,although good early results have been reported after arthroscopic Remplissage for small defects.Larger humeral defects may require complex reconstruction or partial resurfacing.There is currently very limited evidence to support treatment strategies when dealing with bipolar lesions.The aim of this review is to summarise the current evidence regarding the best imaging modalities and treatment strategies in managing this complex problem relating particularly to contact athletes and dislocations related to epileptic seizures. | Eamon Ramhamadany Chetan S Modi | 2016 | World Journal of Orthopedics2016,7,6: | 6 |

| 6 | Anti-arthritis activity of roots of Hemidesmus indicus R.Br.(Anantmul)in rats显示文摘Objective:To investigate the protective effects of hydroalcoholic and its fractions from roots of Hemidesmus indicus on arthritis in in vitro models of rodents.Methods:Preliminary phytochemical analysis and thin-layer chromoatography were performed to analyze constituents of hydroalcoholic extract and its three fraction namely ethyl acetate fraction,chloroform fraction and residual fraction of mot of Hemidesmus indicus.Arthritis rats models were established by Complete Freund’s Adjuvant.The parameters including paw edema,body weight,arthritic index,erythrocyte sedimentation rate,serum rheumatoid factor,serum C-reactive protein,serum nitrite level,and histopathology of synovial joints were observed.Methotrexate was taken as positive control.Results:Rats treated with hydroalcoholic extract(450 mg/kg,p.o.),ethyl acetate (75 mg/kg,p.o.),chloroform(60 mg/kg,p.o) and residual fractions(270 mg/kg,p.o.),showed significant decrease in physical and biochemical parameters compared with arthritic model rats. Hydroalcoholic extract and its ethyl acetate fraction of Hemidesmus indicus showed significantly higher anti-arthritic activity than chloroform and residual fraction.Histopathological analysis demonstrated that both of hydroalcoholic extract and its ethyl acetate fraction had comparable anti-arthritic activity with methotrexates.Conclusions:The present study suggests that Hemidesmus indicus has protective activity against arthritis and the activity might be attributed to presence of terpenoid in hydroalcoholic extract,as well as in ethyl acetate fraction. | Alka Mehta Neeraj K Sethiya Chetan Mehta GB Shah | 2012 | Asian Pacific Journal of Tropical Medicine2012,5,2: | 4 |
| 7 | Experimental investigation of a high aspect ratio,low speed contra-rotating fan stage with complex inflow distortion显示文摘This paper focuses on the response of a high aspect ratio,low speed contra-rotating fan with complex inflow distortion.The total pressure at the inlet is artificially distorted by means of two different sets of screens with different porosities to generate a hub-strong complex distortion and a tip-strong complex distortion.Detailed flow analyses were conducted for the design speed of rotor-1 in combination with off design speeds of rotor-2 both for the design and the peak pressure mass flow rates.In order to understand the extent of inlet distortion,the distortion sector was rotated circumferentially at intervals of 151 to cover the entire annulus.Detailed measurements of total pressure,static pressure,velocity components and flow angles were carried out at the inlet of the first rotor,between the two rotors and at the exit of the second rotor using three seven hole probes.The study reveals a few interesting aspects on the effect of complex inflow distortion on the flow behavior of a contra-rotating stage.The presence of a low porosity screen reduces the magnitude of axial velocity and generates higher spread of distortion near the localized region of placement of the screen.The hub-strong complex distortion has a greater effect of presence of this low porosity screen in both circumferential and radial directions.This leads to higher stagnation pressure variation at the inlet.On the other hand,for the tip-strong complex distortion case,the extent of distortion is observed to be higher in the circumferential direction towards the casing rather than radial.The localized improvement in the flow(in tip-strong inflow distortion)near the tip region improves the performance both in terms of pressure rise and efficiency of stage compared to hub–strong complex distortion. | Chetan Mistry A.M.Pradeepn | 2014 | Propulsion and Power Research2014,3,2: | 3 |
| 8 | 采用延性损伤模型和数值方法预测Ni-Cr基合金在温成形条件下的断裂极限显示文摘为了确定IN625合金的安全成形和断裂极限,在300和673 K下分别进行拉伸成形和深拉延成形实验。将实验获得的基于应力的断裂成形极限图(FFLD)转变为基于应力的σ-FFLD和有效塑性应变(EPS)跟三轴度(η)的关系曲线,以消除断裂极限对应变的过度依赖。为了预测断裂极限,校准7种不同的损伤模型。结果显示,Oh模型对断裂轨迹的预测能力最好,绝对误差最小。虽然实验得到的断裂极限仅用于数值分析,但没有一个损伤模型预测整个应力三轴度范围(0.33<η<0.66)的断裂应变。在不同的温度和润滑条件下深拉延成形圆柱杯,深拉延工艺窗口有助于确定起皱、安全和断裂区域。在润滑条件下,673 K时达到最大的拉延比2。利用Hill 1948各向异性屈服函数对拉伸成形和深拉延成形过程的数值预测结果均在可接受的误差范围内。 | Ayush MORCHHALE Anand BADRISH Nitin KOTKUNDE Swadesh Kumar SINGH Navneet KHANNA Ambuj SAXENA Chetan NIKHARE | 2021 | Transactions of Nonferrous Metals Society of China2021,31,8: | 3 |

| 10 | Observation of an α-synuclein liquid droplet state and its maturation into Lewy body-like assemblies显示文摘Misfoldedα-synudein is a major component of Lewy bodies,which are a hallmark of Parkinson's disease(PD).A large body of evidence shows thatα-synuclein can aggregate into amyloid fibrils,but the relationship between a-synuclein self-assembly and Lewy body formation remains unclear.Here,we show,both in vitro and in a Caenorhabditis elegans model of PD,thatα-synuclein undergoes liquid-liquid phase separation by forming a liquid droplet state,which converts into an amyloid-rich hydrogel with Lewy-body-like properties.This maturation process towards the amyloid state is delayed in the presence of model synaptic vesicles in vitro.Taken together,these results suggest that the formation of Lewy bodies may be linked to the arrested maturation ofα-synuclein condensates in the presence of lipids and other cellular components. | Maarten C.Hardenberg Tessa Sinnige Sam Casford Samuel T.Dada Chetan Poudel Elizabeth A.Robinson Monika Fuxreiter Clemens F.Kaminksi Gabriele S.Kaminski Schierle Ellen A.A.Nollen Christopher M.Dobson Michele Vendruscolo | 2021 | Journal of Molecular Cell Biology2021,13,4: | 3 |

| 16 | Elimination of antibiotic resistance genes and control of horizontal transfer risk by UV-based treatment of drinking water: A mini review显示文摘Antibiotic-resistant bacteria (ARB) and antibiotic resistance genes (ARGs) have been recognized as one of the biggest public health issues of the 21 st century. Both ARB and ARGs have been determined in water after treatment with conventional disinfectants. Ultraviolet (UV) technology has been seen growth in application to disinfect the water. However, UV method alone is not adequate to degrade ARGs in water. Researchers are investigating the combination of UV with other oxidants (chlorine, hydrogen peroxide (H2O2), peroxymonosulfate (PMS), and photocatalysts) to harness the high reactivity of produced reactive species (C1-, C1O -, Cl2-,-OH, and SO4-_) in such processes with constituents of cell (e.g., deoxyribonucleic acid (DNA) and its components) in order to increase the degradation efficiency of ARGs. This paper briefly reviews the current status of different UV-based treatments (UV/chlorination, UV/H2O2, UV/PMS, and UV-photocatalysis) to degrade ARGs and to control horizontal gene transfer (HGT) in water. The review also provides discussion on the mechanism of degradation of ARGs and application of q-PCR and gel electrophoresis to obtain insights of the fate of ARGs during UV-based treatment processes. | Virender K.Sharma Xin Yu Thomas J.McDonald Chetan Jinadatha Dionysios D.Dionysiou Mingbao Feng | 2019 | Frontiers of Environmental Science & Engineering2019,13,3: | 2 |
