| 1 | Bone graft substitutes for spine fusion: A brief review显示文摘Bone graft substitutes are widely used in the field of orthopedics and are extensively used to promote vertebral fusion. Fusion is the most common technique in spine surgery and is used to treat morbidities and relieve discomfort. Allograft and autograft bone substitutes are currently the most commonly used bone grafts to promote fusion. These approaches pose limitations and present complications to the patient. Numerous alternative bone graft substitutes are on the market or have been developed and proposed for application. These options have attempted to promote spine fusion by enhancing osteogenic properties. In this review, we reviewed biology of spine fusion and the current advances in biomedical materials and biological strategies for application in surgical spine fusion. Our findings illustrate that, while many bone graft substitutes perform well as bone graft extenders, only osteoinductive proteins(recombinant bone morphogenetic proteins-2 and osteogenic protein-1) provide evidence for use as both bone enhancers and bone substitutes for specific types of spinal fusion. Tissue engineered hydrogels, synthetic polymer composites and viral based gene therapy also holds the potential to be used for spine fusion in future, though warrants further investigation to be used in clinical practice. | Ashim Gupta Nitin Kukkar Kevin Sharif Benjamin J Main Christine E Albers Saadiq F El-Amin Ⅲ | 2015 | World Journal of Orthopedics2015，6，6： | 4 |
| 2 | 材料模型对高温Ti-6Al-4V合金理论成形极限图预测的影响(英文)显示文摘成形极限图是一种用来描述使板材不发生局部颈缩所需最大主应变的重要图形。它是一种预测板材变形过程中变形极限的方便、有效的工具。本研究中,在400°C和不同样品宽度的条件,通过Nakazima实验得到了Ti-6Al-4V合金的成形极限图。此外,为了使用成形极限图对材料参数进行理论预测,提出了不同的各向异性屈服准则(Barlat 1989,Barlat 1996,Hill 1993)和不同的硬化模型(Hollomon幂定律、Johnson-Cook(JC)模型、改进的Zerilli-Armstrong(m-ZA)和Arrhenius(m-Arr)模型)。结合所提出的屈服准则和本构模型,通过Marciniak和Kuczynski(M-K)理论确定了Ti-6Al-4V合金的成形极限图。结果表明:屈服模型对材料成形极限图的影响大于本构模型的影响。然而,材料的厚度缺陷系数(f_0)与其硬化模型密切相关。Hill(1993)屈服准则最适合于成形极限图右边区域的预测,而Barlat(1989)屈服准最适合于成形极限图左边区域的预测。由于所得到的混合理论成形极限图兼具Barlat(1989)和Hill(1993)屈服模型和m-Arr硬化模型的优点,因此,它与实验得到的成形极限图吻合很好。 | Nitin KOTKUNDE Sashank SRINIVASAN Geetha KRISHNA Amit Kumar GUPTA Swadesh Kumar SINGH | 2016 | Transactions of Nonferrous Metals Society of China2016，26，3： | 2 |

| 4 | Fault Pattern Diagnosis and Classification in Sensor Nodes Using Fall Curve显示文摘The rapid expansion of Internet of Things(IoT)devices deploys various sensors in different applications like homes,cities and offices.IoT applications depend upon the accuracy of sensor data.So,it is necessary to predict faults in the sensor and isolate their cause.A novel primitive technique named fall curve is presented in this paper which characterizes sensor faults.This technique identifies the faulty sensor and determines the correct working of the sensor.Different sources of sensor faults are explained in detail whereas various faults that occurred in sensor nodes available in IoT devices are also presented in tabular form.Fault prediction in digital and analog sensors along with methods of sensor fault prediction are described.There are several advantages and disadvantages of sensor fault prediction methods and the fall curve technique.So,some solutions are provided to overcome the limitations of the fall curve technique.In this paper,a bibliometric analysis is carried out to visually analyze 63 papers fetched from the Scopus database for the past five years.Its novelty is to predict a fault before its occurrence by looking at the fall curve.The sensing of current flow in devices is important to prevent a major loss.So,the fall curves of ACS712 current sensors configured on different devices are drawn for predicting faulty or non-faulty devices.The analysis result proved that if any of the current sensors gets faulty,then the fall curve will differ and the value will immediately drop to zero.Various evaluation metrics for fault prediction are also described in this paper.At last,this paper also addresses some possible open research issues which are important to deal with false IoT sensor data. | Mudita Uppal Deepali Gupta Divya Anand Fahd S.Alharithi Jasem Almotiri Arturo Mansilla Dinesh Singh Nitin Goyal | 2022 | Computers, Materials & Continua2022，，7： | 1 |

| 6 | Triple tube drainage for “difficult” gastroduodenal perforations:A prospective study显示文摘AIM To prospectively study the outcome of difficult gastroduodenal perforations(GDPs) treated by triple tube drainage(TTD) in order to standardize the procedure.METHODS Patients presenting to a single surgical unit of a tertiary hospital with difficult GDPs(large, unfavourable local and systemic factors) were treated with TTD(gastrostomy, duodenostomy and feeding jejunostomy). Postoperative parameters were observed like time to return of bowel sounds, time to start enteral feeds, time to start oral feeds, daily output of all drains, time to clamping/removal of all drains, time for skin to heal, complications, hospital stay, and, mortality. Descriptive statistics were used. RESULTS Between December 2013 and April 2015, 20 patients undergoing TTD for GDP were included, with mean age of 44.6 ± 19.8 years and male:female ratio of 17:3. Mean pre-operative APACHE Ⅱ scores were 10.85 ± 3.55; most GDPs were prepyloric(9/20; 45%) or proximal duodenal(8/20; 40%) and mean size was 1.83 ± 0.59 cm(largest 2.5 cm). Median times of resumption of enteral feeding, removal of gastrostomy, removal of duodenostomy,removal of feeding jejunostomy and oral feeding were 4 d(4-5 IQR), 13(12-16.5 IQR), 16(16.25-22.25 IQR), 18(16.5-24 IQR) and 12 d(10.75-18.5 IQR) respectively. Median hospital stay was 22 d(19-26 IQR) while mortality was 4/20(20%). CONCLUSION TTD for difficult GDP is feasible, easy in the emergency, and patients recover in two-three weeks. It obviates the need for technically demanding and riskier procedures. | Nitin Agarwal Nishant Kumar Malviya Nikhil Gupta Iqbal Singh Sanjay Gupta | 2017 | World Journal of Gastrointestinal Surgery2017，9，1： | 1 |

| 13 | Predictors of vitamin D deficiency in inflammatory bowel disease and health: A Mississippi perspective显示文摘AIM To identify the predictors of vitamin D deficiency in patients with and without inflammatory bowel disease(IBD).METHODS Patients with ulcerative colitis(UC) or Crohn's disease(CD) related diagnostic codes who received medical care at University of Mississippi Medical Center between July 2012 and 2015 were identified. After thorough chart review, we identified patients with biopsy proven IBD who had also been tested for serum 25-hydroxyvitamin D [25(OH)D] concentration. We compared these patients to a previously studied cohort of healthy controls who also had vitamin D concentration checked. Logistic regression analysis was performed to determine the association between vitamin d deficiency and UC, CD, race, age, gender and body mass index(BMI).RESULTS We identified 237 patients with confirmed IBD. Of these, only 211 had a serum 25(OH)D concentrations available in the medical record. The group of healthy controls consisted of 98 individuals with available serum 25(OH)D concentration. 43% of IBD patients were African American(AA). Patients with CD were more likely to have vitamin D concentration checked. Bivariate analysis showed that AA(51% vs 21%, P= 0.00001), subjects with BMI > 30 kg/m^2(39% vs 23% P = 0.01) and CD(40% vs 26%, P = 0.04) were more likely to be vitamin D deficient than vitamin D sufficient. Those with Age > 65 were more likely to be vitamin D sufficient(46% vs 15%, P = 0.04). Multiple regression showed that only BMI > 30 kg/m^2 and AA race are associated with vitamin D deficiency. CONCLUSION BMI > 30 kg/m^2 and AA race are predictive of vitamin D deficiency. Gender, age and diagnosis of IBD are not predictive of vitamin D deficiency. | Kumar Pallav Daniel Riche Warren L May Patrick Sanchez Nitin K Gupta | 2017 | World Journal of Gastroenterology2017，23，4： | 1 |
