| 2 | Parenteral nanosuspensions:a brief review from solubility enhancement to more novel and specific applications显示文摘Advancements in in silico techniques of lead molecule selection have resulted in the failure of around 70% of new chemical entities(NCEs). Some of these molecules are getting rejected at final developmental stage resulting in wastage of money and resources. Unfavourable physicochemical properties affect ADME profile of any efficacious and potent molecule, which may ultimately lead to killing of NCE at final stage. Numerous techniques are being explored including nanocrystals for solubility enhancement purposes. Nanocrystals are the most successful and the ones which had a shorter gap between invention and subsequent commercialization of the first marketed product. Several nanocrystal-based products are commercially available and there is a paradigm shift in using approach from simply being solubility enhancement technique to more novel and specific applications. Some other aspects in relation to parenteral nanosuspensions are concentrations of surfactant to be used, scalability and in vivo fate. At present, there exists a wide gap due to poor understanding of these critical factors,which we have tried to address in this review. This review will focus on parenteral nanosuspensions,covering varied aspects especially stabilizers used, GRAS(Generally Recognized as Safe) status of stabilizers, scalability challenges, issues of physical and chemical stability, solidification techniques to combat stability problems and in vivo fate. | Eknath Ahire Shreya Thakkar Mahesh Darshanwad Manju Misra | 2018 | Acta Pharmaceutica Sinica B2018,8,5: | 6 |
| 3 | Old vs new: Risk factors predicting early onset colorectal cancer显示文摘BACKGROUND Colorectal cancer(CRC)is the second leading cause of all cancer related deaths in the United States and Europe.Although the incidence has been decreasing for individuals’≥50,it has been on the rise for individuals<50.AIM To identify potential risk factors for early-onset CRC.METHODS A population-based cohort analysis using a national database,Explorys,screened all patients with an active electronic medical record from January 2012 to December 2016 with a diagnosis of CRC.Subgroups were stratified based on age(25–49 years vs≥50 years).Demographics,comorbidities,and symptom profiles were recorded and compared between both age groups.Furthermore,the younger group was also compared with a control group consisting of individuals aged 25-49 years within the same timeframe without a diagnosis of CRC.Twentydata points for CRC related factors were analyzed to identify potential risk factors specific to early-onset CRC.RESULTS A total of 68860 patients were identified with CRC,of which 5710(8.3%)were younger than 50 years old,with 4140(73%)between 40-49 years of age.Multivariable analysis was reported using odds ratio(OR)with 95%CI and demonstrated that several factors were associated with an increased risk of CRC in the early-onset group versus the later-onset group.These factors included:African-American race(OR 1.18,95%CI:1.09-1.27,P<0.001),presenting symptoms of abdominal pain(OR 1.82,95%CI:1.72-1.92,P<0.001),rectal pain(OR 1.50,95%CI:1.28-1.77,P<0.001),altered bowel function(OR 1.12,95%CI:1.05-1.19,P=0.0005),having a family history of any cancer(OR 1.78,95%CI:1.67-1.90,P<0.001),gastrointestinal(GI)malignancy(OR 2.36,95%CI:2.18-2.55,P<0.001),polyps(OR 1.41,95%CI:1.08-1.20,P<0.001),and obesity(OR 1.14,95%CI:1.08-1.20,P<0.001).Comparing the early-onset cohort versus the control group,factors that were associated with an increased risk of CRC were:male gender(OR 1.34,95%CI:1.27-1.41),P<0.001),Caucasian(OR 1.48,95%CI:1.40-1.57,P<0.001)and African-American race(OR 1.25,95%CI:1.17-1.35,P<0.001),presenting symptoms of abdominal pain(OR 4.73,95%CI:4.49-4.98,P<0.001),rectal pain(OR 7.48,95%CI:6.42-8.72,P<0.001),altered bowel function(OR 5.51,95%CI:5.19-5.85,P<0.001),rectal bleeding(OR 9.83,95%CI:9.12-10.6,P<0.001),weight loss(OR 7.43,95%CI:6.77-8.15,P<0.001),having a family history of cancer(OR 11.66,95%CI:10.97-12.39,P<0.001),GI malignancy(OR 28.67,95%CI:26.64-30.86,P<0.001),polyps(OR 8.15,95%CI:6.31-10.52,P<0.001),tobacco use(OR 2.46,95%CI:2.33-2.59,P<0.001),alcohol use(OR 1.71,95%CI:1.62-1.80,P<0.001),presence of colitis(OR 4.10,95%CI:3.79-4.43,P<0.001),and obesity(OR 2.88,95%CI:2.74-3.04,P<0.001).CONCLUSION Pending further investigation,these potential risk factors should lower the threshold of suspicion for early CRC and potentially be used to optimize guidelines for early screening. | Aslam R Syed Payal Thakkar Zachary D Horne Heitham Abdul-Baki Gursimran Kochhar Katie Farah Shyam Thakkar | 2019 | World Journal of Gastrointestinal Oncology2019,11,11: | 6 |
| 4 | Response of blood pressure after percutaneous transluminal renal artery angioplasty and stenting显示文摘AIM: To evaluate the short and intermediate term out-come of percutaneous transluminal renal artery angioplasty (PTRA) and stenting particularly on blood pressure (BP) control and renal function and to evaluate predictors of poor BP response after successful PTRA and stenting. METHODS: We conducted a prospective analysis of all patients who underwent PTRA and stenting in our institute between August 2010 to September 2012. A total number of 86 patients were underwent PTRA and renal stenting. Selective angiography was done to confirm at least 70% angiographic stenosis. The predilatation done except few cases with critical stenosis, direct stenting was done in the rest of cases. All patients received aspirin 325 mg orally, and clopidogrel 300 mg orally within 24 h before the procedure. Heparin was used as the procedural anticoagulant agent. Optimal results with TIMI-Ⅲ flow obtained in all cases. Following stent placement, aspirin 150 mg orally once daily was continued for a minimum of 12 mo and clopidogrel 75 mg orally once daily for at least 4 wk. The clinical, radiological, electrocardiography, echocardiography and treatment data of all patients were recorded. The BP measurement, serum creatinine and glomerular filtration rate (GFR) were recorded before the procedure and 1 and 6 mo after PTRA. RESULTS: A total of 86 patients were included in the study. The mean age of study population was 55.87±11.85 years old and 67 (77.9%) of patients were male. There was a significant reduction in both systolic and diastolic BP at 1 mo after the procedure: 170.15±20.10 mmHg vs 146.60±17.32 mmHg and 98.38±10.55 mmHg vs 89.88±9.22 mmHg respectively (P=0.0000). The reduction in BP was constant throughout the follow-up period and was evident 6 mo after the procedure: 144.23±18.19 and 88.26±9.79 mmHg respectively (P=0.0000). However, no improvement in renal function was observed at any time during the follow-up period. After multivariate analysis, we found male sex, low GFR (<60 mL/min) and higher baseline mean BP as a poor predictors of successful outcome on BP response after PTRA and stenting. CONCLUSION: The PTRA and stenting can be considered as an effective therapeutic intervention for improving BP control with minimal effect on renal function. The male sex, higher baseline BP and low GFR are associated with poor BP response after successful PTRA and stenting. | Jayesh S Prajapati Sharad R Jain Hasit Joshi Shaurin Shah Kamal Sharma Sibasis Sahoo Kapil Virparia Ashok Thakkar | 2013 | World Journal of Cardiology2013,5,7: | 3 |
| 5 | Comparison of eigensensitivity and ANN based methods in model updating of an eight-story building显示文摘Analytical models prepared from field drawings do not generally provide results that match with experimental results.The error may be due to uncertainties in the property of materials,size of members and errors in the modelling process.It is important to improve analytical models using experimentally obtained data.For the past several years,data obtained from ambient vibration testing have been successfully used in many cases to update and match dynamic behaviors of analytical models with real structures.This paper presents a comparison between artificial neural network(ANN) and eigensensitivity based model updating of an existing multi-story building.A simple spring-mass analytical model,developed from the structural drawings of the building,is considered and the corresponding spring stiffness and lumped mass of all floors are chosen as updating parameters.The advantages and disadvantages of these updating methods are discussed.The advantage is that both methods ensure a physically meaningful model which canbe further employed in determining structural response and health monitoring. | Prabakaran K Ashok Kumar Shashi Kant Thakkar | 2015 | Earthquake Engineering and Engineering Vibration2015,14,3: | 3 |
| 6 | Application of Statistically Based Experimental Designs to Optimize Cellulase Production and Identification of Gene显示文摘A natural bacterial strain identified as Bacillus amyloliquefaciens MBAA3 using 16S rDNA partial genome sequencing has been studied for optimization of cellulase production.Statistical screening of media components for production of cellulase by B.amyloliquefaciens MBAA3 was carried out by Plackett–Burman design.Plackett–Burman design showed CMC,MgSO4 and pH as significant components influencing the cellulase production from the media components screened by Plackett-Burman fractional factorial design.The optimum concentrations of these significant parameters were determined employing the response surface central composite design,involving three factors and five levels was adopted to acquire the best medium for the production of cellulase enzyme revealed concentration of CMC(1.84 g),MgSO4(0.275 g),and pH(8.5)in media for highest enzyme production.Response surface counter plots revealed that middle level of MgSO4 and middle level of CMC,higher level of CMC and lower level of pH and higher level of MgSO4 with lower level of pH increase the production of cellulase.After optimization cellulase activity increased by 6.81 fold.Presence of cellulase gene in MBAA3 was conformed by the amplification of genomic DNA of MBAA3.A PCR product of cellulase gene of 1500 bp was successfully amplified.The amplified gene was conformed by sequencing the amplified product and sequence was deposited in the gene bank under the accession number KF929416. | Aarti Thakkar Meenu Saraf | 2014 | Natural Products and Bioprospecting2014,4,6: | 3 |
| 7 | Prognostic impact of atrial fibrillation on clinical outcomes of acute coronary syndromes,heart failure and chronic kidney disease显示文摘Atrial fibrillation(AF) is the most common type of sustained arrhythmia,which is now on course to reach epidemic proportions in the elderly population. AF is a commonly encountered comorbidity in patients with cardiac and major non-cardiac diseases. Morbidity and mortality associated with AF makes it a major healthcare burden. The objective of our article is to determine the prognostic impact of AF on acute coronary syndromes,heart failure and chronic kidney disease. Multiple studies have been conducted to determine if AF has an independent role in the overall mortality of such patients. Our review suggests that AF has an independent adverse prognostic impact on the clinical outcomes of acute coronary syndromes,heart failure and chronic kidney disease. | Nileshkumar J Patel Aashay Patel Kanishk Agnihotri Dhaval Pau Samir Patel Badal Thakkar Nikhil Nalluri Deepak Asti Ritesh Kanotra Sabeeda Kadavath Shilpkumar Arora Nilay Patel Achint Patel Azfar Sheikh Neil Patel Apurva O Badheka Abhishek Deshmukh Hakan Paydak Juan Viles-Gonzalez | 2015 | World Journal of Cardiology2015,7,7: | 2 |
| 8 | A comprehensive review of the application of nano-silica in oil well cementing显示文摘Oil and Gas Industry is a Multi-Billion Dollar Industry.Drilling a well is costly,right from exploration to drilling and production to Enhanced Oil Recovery(EOR).Nanotechnology has the potential to introduce revolutionary changes in several areas of the oil and gas industry,such as exploration,drilling,cementation,production,EOR,etc.Use of Nanotechnology in the cement slurry can also achieve solutions to some of the problems pertaining to oil well cementation.Nano-silica is a better alternative compared to conventional additives like calcium chloride and silica,because as compared to calcium chloride and silica,the amount of nano-silica to be added is very small.Nano-silica acts as a multi-functional additive.Upon addition of nano-silica to cement slurry,there is a decrease in the thickening time,an increase in the compressive strength,decrease in porosity and permeability within the cement and also a decrease in the fluid loss.Incorporation of nano-silica ensures proper cementation and greater integrity of the well.Nano-silica helps in decreasing the wait on cement(WOC)time and therefore reduces the overall capital cost.Nano-silica is highly recommended for deep offshore wells where high temperature and high pressure are often encountered.This paper discusses the behavior of Nano-silica at high temperatures and also reviews effects of Nano-silica on various properties of cement. | Akshar Thakkar Aakash Raval Shishir Chandra Manan Shah Anirbid Sircar | 2020 | Petroleum2020,6,2: | 2 |

| 12 | Intraparotid facial nerve schwannoma: A case report显示文摘Facial nerve schwannoma occurring within the parotid gland is a rare tumour. We report a case of schwannoma within the parotid gland in a young female patient, who underwent ultrasound and magnetic resonanceimaging(MRI) and subsequent surgical excision of the lesion. The lesion showed hyperintensity on T2-weighted and diffusion-weighted MRI. There was no adjacent lymphadenopathy. Although hyperintensity on diffusionweighted MRI could suggest malignant tumours, the characteristic 'string sign' provided the clue for the diagnosis of schwannoma. | Abhishek Jaiswal Asit Ranjan Mridha Devajit Nath Ashu Seith Bhalla Alok Thakkar | 2015 | World Journal of Clinical Cases2015,3,3: | 1 |
