| 1 | Nanomaterials for the abatement of cadmium (Ⅱ) ions from water/ wastewater显示文摘The rapid rise of modern industry is the source of unchecked effluents containing many pernicious heavy metals (e.g.,cadmium).To rehabilitate the ecology,food resources,and health of humans and animals,various conventional methodologies are being used in wastewater treatment facilities for the abatement of cadmium.Nonetheless,the development of advanced,economical,and efficient adsorbents is needed because of the many shortcomings of conventional methods (e.g.,high cost,intensive operation,and inefficiency).Recent advancements in materials science and chemistry have introduced the use of nanomaterials,which possess very high specific surface areas and multiple functionalities,for the removal of specific targets such as cadmium.This review explores the recent developments and trends in nanomaterial adsorption technology for the mitigation of cadmium.The paper further surveys the present obstacles and future opportunities for the advancement of nanomaterial-based technologies in the area of water treatment. | Kumar Vikrant Vanish Kumar Kowsalya Vellingiri Ki-Hyun Kim | 2019 | Nano Research2019,12,7: | 5 |
| 2 | Low-velocity simultaneous bilateral femoral neck fracture following long-term antiepileptic therapy:A case report显示文摘BACKGROUND Simultaneous bilateral femoral neck fractures are relatively rare injuries.They are usually associated with underlying metabolic bone disorders or systemic diseases.Long-term use of narcotics and bisphosphonates can also result in similar fracture patterns;however,association of this fracture type with longterm use of antiepileptic drugs is not very common.Only one such case has been reported in the literature.This article describes the second.CASE REPORT We report a case of simultaneous displaced bilateral femoral neck fractures in a 50-year-old epileptic patient,who had taken phenytoin for the past 3 years.The fractures were a result of low-velocity injury following a fall from the bed.The fractures were managed with a bilateral hemi-replacement arthroplasty.Oral bisphosphonates were given to improve the bone quality in the post-operative period.The patient had a good post-operative outcome,that was sustained throughout the entire follow-up period of 1 year.CONCLUSION Antiepileptic drugs should be supplemented with bisphosphonates and vitamin D to improve bone quality and prevent fractures in epileptic patients. | Mohammed Sadiq Vikrant Kulkarni Syed Azher Hussain Mohammed Ismail Mayur Nayak | 2019 | World Journal of Orthopedics2019,10,10: | 5 |
| 3 | Carbon stock estimation for tree species of Sem Mukhem sacred forest in Garhwal Himalaya, India显示文摘Carbon stock estimation was conducted in tree species of Sem Mukhem sacred forest in district Tehri of Garhwal Himalaya, Uttarakhand, India. This forest is dedicated to Nagraj Devta and is dominated by tree species, including Quercus floribunda, Quercus semecarpifolia and Rhododendron arboreum. The highest values of below ground biomass density, total biomass density and total carbon density were (34.81±1.68) Mg·ha-1, (168.26±9.04) Mg·ha-1 and (84.13±4.18) Mg·ha-1 for Pinus wallichiana. Overall values of total biomass density and total carbon density calculated were 1549.704 Mg·ha-1 and 774.77 Mg·ha-1 respectively. Total value of growing stock volume density for all species was 732.56 m3·ha-1 and ranged from (144.97±11.98) m3·ha-1 for Pinus wallichiana to (7.78±1.78) m3·ha-1 for Benthamidia capitata. | Nazir A.

| 4 | Electrospun CNT embedded ZnO nanofiber based biosensor for electrochemical detection of Atrazine: a step closure to single molecule detection显示文摘In this study we have reported the design and development of a facile,sensitive,selective,and label-free electrochemical sensing platform for the detection of atrazine based on MWCNT-embedded ZnO nanofibers.Electrospun nanofibers were characterized using scanning electron microscope(SEM),transmission electron microscope(TEM),X-ray diffraction(XRD),X-ray photoelectron spectroscope(XPS),UV-Visible spectroscope(UV-VIS),and Fourier-transform infrared spectroscope(FTIR).Electrochemical properties of MWCNT-ZnO nanofiber-modified electrodes were assessed using electrochemical impedance spectroscopy(EIS)and cyclic voltammetry(CV).Binding event of atrazine to anti-atrazine antibody,which immobilized on nanofiber-modified electrode via EDC and NHS chemistry,was transduced with EIS.Due to high conductivity,surface area,and low bandgap of MWCNT-ZnO nanofibers,we have achieved the sensitivity and limit of detection(LoD)of sensor as 21.61(KΩμg^(−1) mL^(−1))cm^(−2) and 5.368zM for a wide detection range of 10 zM–1µM.The proposed immunosensing platform has good stability,selectivity,repeatability,and reproducibility,and are less prone to interference. | Patta Supraja Vikrant Singh Siva Rama Krishna Vanjari Shiv Govind Singh | 2020 | Microsystems & Nanoengineering2020,6,1: | 3 |
| 5 | Retrospective analysis of complications related to endoscopic retrograde cholangio-pancreatography in patients with cirrhosis vs patients without cirrhosis显示文摘BACKGROUND There is minimal objective data regarding adverse events related to endoscopic retrograde cholangio-pancreatography(ERCP)in patients with cirrhosis compared to those without cirrhosis and even fewer data comparing complications among cirrhosis patients based on severity of cirrhosis.AIM To determine if patients with cirrhosis are at increased risk of adverse events related to ERCP:mainly pancreatitis,bleeding,perforation,cholangitis,and mortality;And to see if higher Child-Pugh(CP)score and Model for End-Stage Liver Disease(MELD)score are associated with higher post-ERCP complications.METHODS We performed a retrospective analysis of 692 patients who underwent ERCP and analyzed the impact of cirrhosis etiology,gender,type of sedation used during procedure,interventions performed,and co-morbidities on the rate of complications in cirrhosis patients as compared to non-cirrhosis patients.RESULTS Overall complications were higher in those with cirrhosis as compared to those without cirrhosis(P=0.015 at significance level of 0.05).CP class,especially CP class C,was shown to be associated with a significantly higher rate of ERCP complications as compared to CP class A and CP class B(P=0.010 at significance level of 0.05).CONCLUSION The results of our study reaffirm that liver cirrhosis has an impact on the occurrence of complications during ERCP.Our study shows that CP class seems to be more reliable as compared to MELD score in predicting complications of ERCP in cirrhosis patients. | Michelle Bernshteyn Linda Hu Umair Masood Anuj Vikrant Sharma Danning Huang Bishnu Sapkota | 2021 | World Journal of Hepatology2021,13,4: | 3 |
| 6 | Clinicopathological spectrum of snake bite-induced acute kidney injury from India显示文摘AIM To study the clinico-pathological spectrum of snake bite-induced acute kidney injury(AKI).METHODS A retrospective study of patients admitted at Indira Gandhi Medical College Hospital,Shimla with snake bite-induced AKI from July 2003 to June 2016.Medical records were evaluated for patient's information on demographic,clinical characteristics,complications and outcome.Outcomes of duration of hospital stay,requirement for intensive care unit support,treatment with dialysis,survival and mortality were analyzed.The survival and non survival groups were compared to see the difference in the demographic factors,clinical characteristics,laboratory results,and complications.In patients subjected to kidney biopsy,the findings of histopathological examination of the kidney biopsies were also analyzed.RESULTS One hundred and twenty-one patients were diagnosed with snake bite-induced AKI.Mean age was 42.2 ± 15.1 years and majority(58%) were women.Clinical details were available in 88 patients.The mean duration of arrival at hospital was 3.4 ± 3.7 d with a range of 1 to30 d.Eighty percent had oliguria and 55% had history of having passed red or brown colored urine.Coagulation defect was seen in 89% patients.The hematological and biochemical laboratory abnormalities were:Anemia(80.7%),leukocytosis(75%),thrombocytopenia(47.7%),hyperkalemia(25%),severe metabolic acidosis(39.8%),hepatic dysfunction(40.9%),hemolysis(85.2%) and rhabdomyolysis(68.2%).Main complications were:Gastrointestinal bleed(12.5%),seizure/encephalopathy(10.2%),hypertension,pneumonia/acute respiratory distress syndrome(ARDS) and disseminated intravascular coagulation(9.1% each),hypotension and multi organ failure(MOF)(4.5% each).Eighty-two percent patients required renal replacement therapy.One hundred and ten(90.9%) patient survived and 11(9.1%) patients died.As compared to the survival group,the white blood cell count(P = 0.023) and bilirubin levels(P = 0.006) were significant higher and albumin levels were significantly lower(0.005) in patients who died.The proportion of patients with pneumonia/ARDS(P = 0.001),seizure/encephalopathy(P = 0.005),MOF(P = 0.05) and need for intensive care unit support(0.001) was significantly higher and duration of hospital stay was significantly shorter(P = 0.012) in patients who died.Kidney biopsy was done in total of 22 patients.Predominant lesion on kidney biopsy was acute tubular necrosis(ATN) in 20(91%) cases.In 11 cases had severe ATN and in other nine(41%) cases kidney biopsy showed features of ATN associated with mild to moderate acute interstitial nephritis(AIN).One patient only had moderate AIN and one had patchy renal cortical necrosis(RCN).CONCLUSION AKI due to snake bite is severe and a high proportion requires renal replacement therapy.On renal histology ATN and AIN are common,RCN is rare. | Sanjay Vikrant Ajay Jaryal Anupam Parashar | 2017 | World Journal of Nephrology2017,6,3: | 2 |

| 8 | A comparative analysis of distal locked and unlocked long proximal femoral nail antirotation (PFNA-II) in the fixation of stable intertrochanteric fractures显示文摘Purpose:Long proximal femoral nail anti-rotation (PFNA-II) is a preferred implant in recent years for fixation of pertrochanteric fractures,especially in osteoporotic patients.The purpose of this study is to prospectively investigate the effect of distal locking in long PFNA-II fixation of stable intertrochanteric fractures.Methods:A total of 58 patients with isolated stable intertrochanteric fractures and treated in our hospital during the study period of 2017–2019 by distal locked or unlocked long PFNA-II fixation were included in this study.Patients who had multiple injuries or open fractures were excluded.There were 40 female and 18 male patients,with 33 affecting the left side and 25 the right side.Of them,31 belonged to the distal locked group (group A) and 27 to the unlocked group (group B).Surgical procedures and implants used in both groups were similar except for the distal locking of the nails.General data (age,gender,fracture side,etc.) showed no significant difference between two groups (allp > 0.05).The intraoperative parameters like operative time,radiation exposure and follow-up parameters like functional and radiological outcomes were recorded and compared.Statistical tests like the independent samplest-test Fischer’’s exact and Chi-square test were used to analyze association.Results:The distribution of the fractures according to AO/OTA classification and 31A1.2 type of intertrochanteric fractures were most common in our study.All the included fractures united and the average functional outcome in both groups were good and comparable at the end of one year.The operative time (mL,107.1 ± 12.6vs.77.0 ± 12.0,p < 0.001) and radiation exposure (s,78.6 ± 11.0vs.40.3 ± 9.3,p < 0.001) were significantly less among the patients in group B.Fracture consolidation,three months after the operative procedures,was seen in a significantly greater proportion of patients in group B (92.6%vs.67.7%,p = 0.025).Hardware irritation because of distal locking bolt was exclusively seen in group A,however this was not statistically significant (p = 0.241).Conclusion:We conclude that,in fixation of stable intertrochanteric fractures by long PFNA-II nail,distal locking not only increases the operative time and radiation exposure but also delays the fracture consolidation and increases the chances of hardware irritation,and hence is not required. | Atmananda Hegde Vikrant Khanna Prajwal Mane Chethan Shetty Nitin Joseph | 2023 | Chinese Journal of Traumatology2023,26,2: | 1 |
