| 1 | Nanomaterials for sensing of formaldehyde in air: Principles, applications, and performance evaluation显示文摘Despite the improvement in sensing technologies, detection of small and highly reactive molecules like formaldehyde remains a highly challenging area of research. Applications of nanomaterials/nanostructures and their composites have increased as effective sensing platforms (e.g., reaction time, sensitivity, and selectivity) for the detection of aqueous or gaseous formaldehyde based on diverse sensing principles. In this review, the basic aspects of important nanomaterial-based sensing systems (e.g., electrochemical, electrical, biological, and mass variation sensors) were evaluated in relation to performance, cost, and practicality of sensing gas phase formaldehyde. Accordingly, existing knowledge gaps in such applications were assessed in various respects along with suitable recommendations for building a new roadmap for the expansion of chemical sensing technology of gas phase formaldehyde. | Deepak Kukkar Kowsalya Vellingiri Rajnish Kaur Sanjeev Kumar Bhardwaj Akash Deep Ki-Hyun Kim | 2019 | Nano Research2019,12,2: | 3 |
| 2 | Sitagliptin,sitagliptin and metformin,or sitagliptin and amitriptyline attenuate streptozotocin-nicotinamide induced diabetic neuropathy in rats显示文摘Diabetic neuropathies are a family of nerve disorders caused by diabetes.Symptoms of the disease include nerve palsy,mononeuropathy,mononeuropathy multiplex,diabetic amyotrophy,painful polyneuropathy,autonomic neuropathy,and thoracoabdominal neuropathy.In this study,type 2 diabetes in rats was induced with nicotinamidestreptozotocin.Drug treatment was initiated on the d 15,with the combination regimen of metformin,pioglitazone and glimipiride or metformin and sitagliptin or sitagliptin,amitriptyline and sitagliptin and led to significantly improved glycemic control,increased grip strength and paw jumping response on d 21,28 and 35(P < 0.001).Significant increases in blood protein levels and decreases in urinary protein levels were observed in the animals treated with the different regimens on d 21,28 and 35(P < 0.001).Combined treatment of streptozotocin and nicotinamide caused marked degeneration of nerve cells,while administration of metformin and sitagliptin showed tissue regeneration and no body weight gain.In conclusion,treatment with sitagliptin and sitagliptin combined with metformin or amitriptyline results in no body weight gain,but causes an increase in grip strength and pain sensitivity,exhibits neural protection,and reverses the alteration of biochemical parameters in rats with streptozotocin-nicotinamide induced type 2 diabetes. | Ashish Kumar Sharma Akash Sharma Rita Kumari Kunal Kishore Divya Sharma Bharthu Parthsarthi Srinivasan Ashok Sharma Santosh Kumar Singh Samir Gaur Vijay Singh Jatav Prashant Sharma Varnika Srivastava Sneha Joshi Megha Joshi Prashant Kumar Dhakad Davender Singh Kanawat Akanksha Mishra Anil Sharma Dharmendra Singh Ravinder Pal Singh Himmat Singh Chawda Rambir Singh Sachin Kumar Raikwar Muneem Kumar Kurmi Pankaj Khatri Ashutosh Agarwal Arshee Munajjam | 2012 | The Journal of Biomedical Research2012,26,3: | 2 |
| 3 | 简易转速测量系统设计显示文摘介绍了一种基于定时器的转速测量系统的设计与开发。使用直流电动机的转轴来测量其转速,定时器IC 555用于不稳定模式。使用数字存储示波器(DSO)测量的定时器输出波形的频率几乎与转轴的转速成线性比例,而这个转速又与外部输入电压水平的变化成线性关系,由此得到了定时器输出波形频率与转速之间的线性关系。该系统的主要优点是线性输入-输出,体积小,便于携带且成本低。 | Akash Kumar Anindya Debnath Antar Banik Kabirul Islam Mondal Partha Pratim Biswas Rik Bhattacharyya T K Maiti | 2020 | Journal of Measurement Science and Instrumentation2020,11,2: | 2 |
| 4 | On-road emissions of CO,CO2 and NOx from four wheeler and emission estimates for Delhi显示文摘This study presents the emission factor of gaseous pollutants(CO, CO_2, and NO X) from on-road tailpipe measurement of 14 passenger cars of different types of fuel and vintage. The trolley equipped with stainless steel duct, vane probe velocity meter, flue gas analyzer, Nondispersive infra red(NDIR) CO_2 analyzer, temperature, and relative humidity(RH) sensors was connected to the vehicle using a towing system. Lower CO and higher NO X emissions were observed from new diesel cars(post 2010) compared to old cars(post 2005), which implied that new technological advancement in diesel fueled passenger cars to reduce CO emission is a successful venture,however, the use of turbo charger in diesel cars to achieve high temperature combustion might have resulted in increased NO X emissions. Based on the measured emission factors(g/kg), and fuel consumption(kg), the average and 95% confidence interval(CI) bound estimates of CO, CO_2,and NO X from four wheeler(4W) in Delhi for the year 2012 were 15.7(1.4–37.1), 6234(386–12,252),and 30.4(0.0–103) Gg/year, respectively. The contribution of diesel, gasoline and compressed natural gas(CNG) to total CO, CO_2 and NO X emissions were 7:84:9, 50:48:2 and 58:41:1respectively. The present work indicated that the age and the maintenance of vehicle both are important factors in emission assessment therefore, more systematic repetitive measurements covering wide range of vehicles of different age groups, engine capacity, and maintenance level is needed for refining the emission factors with CI. | Jaiprakash Gazala Habib Anil Kumar Akash Sharma Minza Haider | 2017 | Journal of Environmental Sciences2017,29,3: | 1 |
| 5 | Involvement of adenosine and standardization of aqueous extract of garlic(Allium sativum Linn.)on cardioprotective and cardiodepressant properties in ischemic preconditioning and myocardial ischemia-reperfusion induced cardiac injury显示文摘The present study investigated the effect of garlic(Allium sativum Linn.)aqueous extracts on ischemic preconditioning and ischemia-reperfusion induced cardiac injury,as well as adenosine involvement in ischemic preconditioning and garlic extract induced cardioprotection.A model of ischemia-reperfusion injury was established using Langendorff apparatus.Aqueous extract of garlic dose was standardized(0.5%,0.4%,0.3%,0.2%,0.1%,0.07%,0.05%,0.03%,0.01%),and the 0.05% dose was found to be the most effective.Higher doses(more than 0.05%)were highly toxic,causing arrhythmia and cardiodepression,whereas the lower doses were ineffective.Garlic exaggerated the cardioprotective effect of ischemic preconditioning.The cardioprotective effect of ischemic preconditioning and garlic cardioprotection was significantly attenuated by theophylline(1,000 μmol/L)and 8-SPT(10 mg/kg,i.p.)and expressed by increased myocardial infarct size,increased LDH level,and reduced nitrite and adenosine levels.These findings suggest that adenosine is involved in the pharmacological and molecular mechanism of garlic induced cardioprotection and mediated by the modulation of nitric oxide. | Ashish Kumar Sharma Arshee Munajjam Bhawna Vaishnav Richa Sharma Ashok Sharma Kunal Kishore Akash Sharma Divya Sharma Rita Kumari Ashish Tiwari Santosh Kumar Singh Samir Gaur Vijay Singh Jatav Barthu Parthi Srinivasan Shyam Sunder Agarwal | 2012 | The Journal of Biomedical Research2012,26,1: | 1 |

| 8 | Emerging role of non-invasive and liquid biopsy biomarkers in pancreatic cancer显示文摘A global increase in the incidence of pancreatic cancer(PanCa)presents a major concern and health burden.The traditional tissue-based diagnostic techniques provided a major way forward for molecular diagnostics;however,they face limitations based on diagnosis-associated difficulties and concerns surrounding tissue availability in the clinical setting.Late disease development with asymptomatic behavior is a drawback in the case of existing diagnostic procedures.The capability of cell free markers in discriminating PanCa from autoimmune pancreatitis and chronic pancreatitis along with other precancerous lesions can be a boon to clinicians.Early-stage diagnosis of PanCa can be achieved only if these biomarkers specifically discriminate the non-carcinogenic disease stage from malignancy with respect to tumor stages.In this review,we comprehensively described the non-invasive disease detection approaches and why these approaches are gaining popularity for their early-stage diagnostic capability and associated clinical feasibility. | Akash Bararia Prosenjeet Chakraborty Paromita Roy Bitan Kumar Chattopadhay Amlan Das Aniruddha Chatterjee Nilabja Sikdar | 2023 | World Journal of Gastroenterology2023,29,15: | 1 |
| 9 | Unreported complication of Bravo p H capsule dislodged into the pyriform sinus显示文摘We report an unexpected, previously unreported complication of Bravo p H capsule dislodgement. During Bravo p H testing of a 44-year-old man with gastroesophageal reflux disease, we were unable to endoscopically visualize the capsule attached to the esophageal wall after deployment. After multiple attempts to detect the capsule, it was visualized in the left pyriform sinus. As there was significant risk for pulmonary dislodgement, ENT and pulmonary physicians were immediately consulted to review options for safe removal. Ultimately, ENT successfully retrieved the capsule with a foreign body removal forceps. The Bravo p H test is generally a well-tolerated diagnostic tool used to confirm the presence of abnormal esophageal acid reflux. While few complications have been reported, technical difficulties can occur, including poor data reception, misplacement, and early dislodgement. Rarely, more serious complications can occur, ranging from esophageal wall trauma to capsule aspiration. Gastroenterologists performing this procedure should be aware of the low, but nontrivial, risk of complications. | Akash Kumar Elisabeth Kramer Sita Chokhavatia | 2015 | World Journal of Gastrointestinal Endoscopy2015,7,5: | 1 |

| 17 | Packed with pills-obstructing duodenal web in the setting of intestinal malrotation:A case report显示文摘BACKGROUND The incidence of intestinal malrotation in adults has been reported to only be about 0.2%.Duodenal web as a cause of intestinal obstruction is rare,with an incidence of about 1:20000-1:40000.Furthermore,when described,these conditions are usually seen in early life and very infrequently in adulthood.CASE SUMMARY We report a case of a middle-aged woman with intestinal malrotation who presented with a three-month history of right-sided abdominal pain,early satiety,and a 22-pound weight loss.Patient underwent an esophagogastroduodenoscopy,which demonstrated numerous retained pills in a deformed first portion of the duodenum,concerning for a partial gastric outlet obstruction.An upper gastrointestinal series showed marked distention of the proximal duodenum with retained debris and the presence of a windsock sign,increasing the suspicion of a duodenal web.The patient subsequently underwent surgical intervention where a duodenal web with two lumens was noted and resected,opening the duodenum.There were over 150 pill capsules that were removed.The patient is doing well after this intervention.CONCLUSION Both intestinal malrotation and duodenal webs are infrequently encountered in the adult population.These pathologies can also present with nonspecific abdominal symptoms such as chronic abdominal pain and nausea.Hence,providers might not consider these pathologies in the differential for patients who present with vague symptoms which can lead to delay in management and increased mortality and morbidity. | Kimberline Chew Sarah Bellemare Akash Kumar | 2023 | World Journal of Gastrointestinal Endoscopy2023,15,2: | 0 |
| 18 | Investigation of 58Ni(n, p)58Co reaction cross-section with covariance analysis显示文摘The excitation function of the 58Ni(n,p)58Co reaction was measured using the well-established neutron activation technique andγ-ray spectroscopy.Neutrons in the energy range of 1.7 to 2.7 MeV were generated using the 7Li(p,n)reaction.The neutron flux was measured using the standard 115In(n,n’)115mIn monitor reaction.The results of the neutron spectrum averaged cross-section of 58Ni(n,p)58Co reactions were compared with existing cross-section data available in the EXFOR data library as well as with various evaluated data libraries such as ENDF/B-VIII.0,JEFF-3.3,JENDL-4.0,and CENDL-3.2.Theoretical calculations were performed using the nuclear reaction code TALYS.Various nuclear level density(NLD)models were tested,and their results were compared with the present findings.Realistic NLDs were also obtained through the spectral distribution method(SDM).The cross-section results,along with the absolute errors,were obtained by investigating the uncertainty propagation and using the covariance technique.Corrections forγ-ray true coincidence summing,low-energy background neutrons,andγ-ray self attenuation were performed.The experimental cross-section obtained in the present study is consistent with previously published experimental data,evaluated libraries,and theoretical calculations carried out using the TALYS code. | Akash Hingu S.Mukherjee Siddharth Parashari Arora Sangeeta A.Gandhi Mahima Upadhyay Mahesh Choudhary Sumit Bamal Namrata Singh G.Mishra Sukanya De Saurav Sood Sajin Prasad G.Saxena Ajay Kumar R.G.Thomas B.K.Agrawal K.Katovsky A.Kumar | 2024 | Chinese Physics C2024,48,2: | 0 |
| 19 | Role of fibrinogen,albumin and fibrinogen to albumin ratio in determining angiographic severity and outcomes in acute coronary syndrome显示文摘BACKGROUND Coronavirus disease 2019(COVID-19)pandemic unmasked the huge deficit in healthcare resources worldwide.It highlighted the need for efficient risk stratification in management of cardiovascular emergencies.AIM To study the applicability of the old,available and affordable nonconventional biomarkers:albumin and fibrinogen in their ability to predict angiographic severity and clinical outcomes in patients with acute coronary syndrome(ACS).METHODS In this prospective,observational study,166 consecutive patients with ACS were enrolled.Fibrinogen,albumin and their ratio were determined from serum.Patients with underlying chronic liver disease,active malignancy,autoimmune disease,active COVID-19 infection and undergoing thrombolysis were excluded.RESULTS Mean age of the population was 60.5±1.5 years,74.1%being males.ST elevation myocardial infarction(STEMI)was most common presentation of ACS seen in 57%patients.Fibrinogen albumin ratio(FAR)≥19.2,had a sensitivity of 76.9%and specificity of 78.9%[area under the receiver operating characteristic curves(AUROC)=0.8,P=0.001]to predict≤thrombolysis in myocardial infarction(TIMI)1 flow in culprit artery in STEMI patients.Even in non-STEMI patients,FAR≥18.85 predicted the same with 80%sensitivity and 63%specificity(AUROC=0.715,P=0.006).CONCLUSION Novel biomarkers,with their high cost,lack of availability and long turn over time are impractical for real-world use.Identifying≤TIMI 1 flow in the culprit artery has significant impact of management and outcome.Our study has shown that readily available biomarkers like fibrinogen and albumin can help identify these high-risk patients with good accuracy.This allows risk-stratification and individualization of treatment in ACS. | Kunaal Makkar Yash Paul Sharma Akash Batta Juniali Hatwal Prashant Kumar Panda | 2023 | World Journal of Cardiology2023,15,1: | 0 |
| 20 | A perspective review on the biosynthesis of plant-based secondary metabolites and their application as potent drugs显示文摘Many phytochemicals and their derived metabolites produced by plants are extensively employed in commercial goods,pharmaceutical products as well as in the environmental and medicalfields.However,these secondary metabolites obtained from plants are in low amounts,and it is difficult to synthesize them at the industrial level.Despite these challenges,they may be utilized for a variety of medicinal products that are either available in the market or are being researched and tested.Secondary metabolites are complex compounds that exhibit chirality.Further,under controlled conditions with elicitors,desired secondary metabolites may be produced from plant cell cultures.This review emphasizes the various aspects of secondary metabolites including their types,synthesis,and applications as medicinal products.The article aims to promote the use of plant secondary metabolites in the management and treatment of various diseases. | JHILAM PRAMANIK AKASH KUMAR SARVESH RUSTAGI MEHAK KATYAL SHEETAL THAKUR JUTISHNA BORA SUMIRA MALIK ANCHAL TREHAN NAYAN TALUKDAR PETR SLAMA | 2024 | BIOCELL2024,48,4: | 0 |
