1Performance analysis of deep learning CNN models for disease detection in plants using image segmentation显示文摘Food security for the 7 billion people on earth requires minimizing crop damage by timely detectionofdiseases.Most deep learningmodels forautomated detectionof diseases in plants suffer fromthe fatal flaw that once tested on independent data,their performance drops significantly.This work investigates a potential solution to this problem by using segmented image data to train the convolutional neural network(CNN)models.As compared to the F-CNN model trained using full images,S-CNN model trained using segmented imagesmore than doubles in performance to 98.6%accuracy when tested on independent data previously unseen by the models even with 10 disease classes.Not only this,by using tomato plant and target spot disease type as an example,we show that the confidence of self-classification for S-CNN model improves significantly over F-CNN model.This research work brings applicability of automated methods closer to non-experts for timely detection of diseases.Parul Sharma Yash Paul Singh Berwal Wiqas Ghai 2020Information Processing in Agriculture2020,7,4:5

3Metabolic effects of obesity:A review显示文摘With the many recent advances in the biomedical world,vast changes are taking place in our growing knowledge of the physiological aspects of almost all the tissues and organs of the human body.One of the most prevalent topics of discussion is the question of obesity and its effect on the metabolic changes in the human body.The original classical role of adipose tissue as an energy storage organ has been greatly modified.We now know that it is an endocrine organ,producing adipokines like leptin,adiponectin,visfatin,resistin,apelin,etc,which modulate metabolic processes in the body.Since obesity is associated with an increase in the adipose tissue mass,these hormones may be expected to be produced in increased concentrations and may thus have a significant impact on the macronutrient metabolism.Further,these adipokines may interact with long term energy modulators like insulin.Even though the scientific community has started unravelling the mysteries of the close linkage between obesity,its hormones and their physiological effects,a lot still remains to be discovered.The present discussion makes an attempt to trace the basic modern day concepts of the role of obesity in various metabolic processes.Parul Singla Animesh Bardoloi Anuj A Parkash 2010World Journal of Diabetes2010,1,3:5
4营养不良:实验室指标vs营养评估显示文摘营养不良是患者并发症发生率和病死率的一项独立危险因素,并造成医疗费用的增高。然而,由于对营养不良没有一个统一的定义,也没有一个标准的营养不良筛查/诊断方法,导致全世界各地的医生对营养不良在认识上十分混乱,各地的临床实践也有着各不相同的标准。作为营养不良的危险因素,炎症的作用近期已被证实。组织学上,一些血清蛋白如白蛋白和前白蛋白被广泛用于监测患者的营养状态。然而,目前的研究热点是采用恰当的营养状态体格检查(NFPE)来诊断营养不良。目前认为,实验室指标本身不太可靠,只能作为NFPE的一个补充。今后的研究中需要筛选出一些诊断营养不良的血清生物学标志物,这些标志物必须是不受炎症状态影响且具有无创及价格相对低廉的优势。然而,一个完全的NFPE在营养不良的诊断中具有无可替代的作用。Shishira Bharadwaj Shaiva Ginoya Parul Tandon Tushar D.Gohel John Guirguis Hiren Vallabh Andrea Jevenn Ibrahim Hanouneh 2016Gastroenterology Report2016,4,4:5
5Comparative analysis of APACHE-Ⅱ and P-POSSUM scoring systems in predicting postoperative mortality in patients undergoing emergency laparotomy显示文摘BACKGROUND Laparotomy remains one of the commonest emergency surgical procedures.Early prognostic evaluation would aid in selecting the high-risk patients for an aggressive treatment.Awareness about risks could potentially contribute to the quality of perioperative care and optimum utilization of resources.Portsmouth modification of Physiological and operative severity for the enumeration of mortality and morbidity (P-POSSUM) and the acute physiology and chronic health evaluation Ⅱ(APACHE-Ⅱ) have been the most widely used scoring systems for emergency laparotomies.It is always better to have a single scoring system to predict outcomes and audit healthcare organizations.AIM To compare the ability of APACHE-II and P-POSSUM to predict postoperative morbidity and mortality in patients undergoing emergency laparotomy.METHODS All patients undergoing emergency laparotomy at the Tata Main Hospital,Jamshedpur between December 2013 and November 2014 were included in the study.In this observational study,P-POSSUM and APACHE-Ⅱ scoring were done,and the outcome analysis evaluated with mortality being the primary outcome.RESULTS For P-POSSUM,at a cut off value of 63 to predict mortality using receiver operating characteristics curve analysis,the area under the curve was 0.989;and for APACHE-Ⅱ,at the cut off value of 24,the area under the curve was 0.965.CONCLUSION Because the ability of APACHE-Ⅱ to predict mortality was similar to P-POSSUM and APACHE-Ⅱ does not need scoring for intra-operative findings and histopathology reports,APACHE-Ⅱ can be used pre-operatively to assess the risk in patients undergoing emergency laparotomy.However,for audit purposes,either of the two scoring systems can be used.Deb Sanjay Nag Ankur Dembla Pratap Rudra Mahanty Shashi Kant Abhishek Chatterjee Devi Prasad Samaddar Parul Chugh 2019World Journal of Clinical Cases2019,7,16:5
6Role of angiotensin converting enzyme and angiotensinogen gene polymorphisms in angiotensin converting enzyme inhibitor-mediated antiproteinuric action in type 2 diabetic nephropathy patients显示文摘AIM To investigate the role of genetic variants of angiotensin converting enzyme(ACE) and angiotensinogen(AGT) genes in the antiproteinuric efficacy of ACE inhibitor therapy in diabetic nephropathy(DN) patients.METHODS In the present study, 270 type 2 diabetes mellitus patients with nephropathy were enrolled and treated with ACE inhibitor(ramipril) and followed at 6 mo for renal function and albumin excretion by estimating serum creatinine, end stage renal disease, and albumin/creatinine ratio(ACR) in urine. Genotyping of ACE I/D and AGT M235 T polymorphisms were performed by using primer specific polymerase chain reaction(PCR) and PCR-RFLP techniques, respectively. RESULTS Forty-eight percent of DN patients(responders) benefited with respect to proteinuria from ACE inhibitor therapy at 6 mo follow-up. A significant reduction in ACR was observed after 6 mo treatment with ACE inhibitor irrespective of whether DN patients were micro-albuminuric(≥ 30 and < 300 mg/g creatinine) or macro-albuminuric(≥ 300 mg/g creatinine) at the time of enrollment. However, macro-albuminuric patients(55%) showed better response to therapy. A reduction in urinary ACR was found independent of genotypes of ACE I/D and AGT M235 T polymorphisms although macro-albuminuric patients having TT genotype showed statistically insignificant increased response(72%). CONCLUSION ACE inhibitor therapy reduced urinary ACR by ≥ 30% in 50% of DN patients and the response is independent of ACE I/D and AGT M235 T polymorphisms.Neerja Aggarwal Pawan Kumar Kare Parul Varshney Om Prakash Kalra Sri Venkata Madhu Basu Dev Banerjee Anil Yadav Alpana Raizada Ashok Kumar Tripathi 2017World Journal of Diabetes2017,8,3:4
7Aerobic bacterial flora of the normal conjunctiva at high altitude area of Shimla Hills in India:a hospital based study显示文摘AIM:To study the normal aerobic conjunctival flora in lower to mid Himalayan region of Shimla Hills.METHODS:Samples from normal conjunctiva of 200 individuals above the age of 13 years who visited Indira Gandhi Medical College Hospital Shimla for refraction or cataract surgery were taken by anaesthetising the conjunctival sac with sterile 4% Xylocaine solution.Samples were obtained by gently rubbing lower fornix with a sterile cotton wool swab moistened with normal saline and keeping the eye lids wide apart to avoid contamination from lid margins.It was immediately inoculated in Brain Heart infusion and subjected to standard aerobic culture and identification techniques.RESULTS:Totally,72 eyes(36%) conjunctival sacs were sterile.Predominant aerobes isolated were Staphylococcus spp.in 120(60%) followed by Haemophilus in 16(8%),diphtheroids in 10(5%),and Escherichia coli(E.coli) in 4(2%).A single aerobe was isolated from 98 eyes(49%) while 30 eyes(15%) yielded more than 1 aerobe.Staphylococcus epidermidis(S.epidermidis) was the most common bacterium,found alone in 58 eyes(29%) and in combination with another aerobe in 30 eyes(15%),followed by Staphylococcus aureus(S.aureus) in 18(9%) and 10 eyes(5%) respectively.CONCLUSION:S.epidermidis is the most common commensal organism followed by Haemophilus species.diphtheroids occupied the third position which otherwise are found more abundantly in literature.Pathogens like S.aureus,Staphylococcus citreus and E.coli were also found.Therefore,preoperative administration of topical broad spectrum antibiotics is extremely important in prophylaxis against ocular infection.The variation in microflora of normal conjunctiva in this part of world can be attributed to geographical,climatic and ethnic characteristics of the population under study.Sharma Parmeshri Dass Sharma Neelam Gupta Ravinder Kumar Singh Parul 2013International Journal of Ophthalmology(English edition)2013,6,5:4
8热带地区相对湿度的季节性变化影响果蝇Drosophila jambulina体色多型性和水分平衡(英文)显示文摘在印度次大陆的亚热带地区,秋天冷而干燥,春天湿润。变温性果蝇所具有的抗干燥性有助于其度过较为干旱的气候条件。Drosophila jambulina具有体色二型性。已有研究表明,随湿度变化,D.jambulina热带种群始终保持体色多型性,这与热条件下体色黑化相反,且该热带物种中体色分化频率随季节性变化,这符合黑化-干燥假说。但是两种色型的D.jambulina产生这类气候适应的机理尚不明了。为了检验干燥相关性状生理基础的分化与对气候条件的色型特异性适应相关这一假说,我们利用分别在17℃和25℃、低湿(40%RH)和高湿(80%RH)条件下饲养获得的两种色型的D.jambulina,检测了其水分平衡对相对湿度、温度、及温湿度相互作用的反应。我们发现,在低相对湿度下,两种温度下饲养的深色型果蝇的生理和脱水性状数值显著高于浅色型。对两种色型果蝇的水分收支情况进行的比较分析表明,在低相对湿度下,深色型果蝇的含水量较高、水分损失率较低、抗脱水能力较强,使其具有更强的抗干燥性。在干燥胁迫过程中,两种色型的果蝇均以碳水化合物作为代谢燃料,但是在低湿条件下,深色果蝇中贮存碳水化合物的含量明显要高。而且,在两种湿度条件下,这两种色型果蝇之间的总能量收支显著不同。据此认为,D.jambulina的水分平衡相关性状表现出的色型特异性分化与其对湿热生境的适应相关。Ekta KHASA Parul BADHWAR Veer BHAN 2013昆虫学报2013,56,12:3
9Prevalence of excessive internet use and its correlation with associated psychopathology in 11th and 12th grade students显示文摘Background Globally, the number of internet users has crossed the three-billion mark, while in India users grew over 17% in the first 6 months of 2015 to 354 million. This study presented a background on internet use and the existence of excessive internet use. Aim To study the extent of internet use in 11th and 12th grade students and the psychopathology, if any, associated with excessive internet use. Methods 426 students who met the inclusion criteria were recruited from 11 th and 12th grade classes from Kendriya Vidyalaya, New Delhi, India, and were assessed by Young's Internet Addiction Test and the Strength and Difficulties Questionnaire. Results Among the 426 students, the mean internet addiction total score was 36.63 (20.78), which indicated mild level of internet addiction. 1.41%(six students) was diagnosed as excessive internet users, while 30.28% and 23.94% were classified as moderate and mild internet users, respectively. The prevalence of internet addiction between gender was 58.22% in males and 41.78% in females. While both positive (prosocial) and negative (hyperactivity, emotional, conduct and peer problem) impacts of internet use were reported by students, in the current study excessive use of internet had a negative impact on students' lives as compared with positive impact, which was statistically significant (p<0.0001). Conclusion Excessive internet use led to abnormal behaviours which cause negative consequences to users. Early diagnosis of risk factors related to excessive internet use, provides education about responsible use and supervision of students by family members.Nitin Kumar Arvind Kumar Subodh Kumar Mahto Manish Kandpal Smita Neelkanth Deshpande Parul Tanwar 2019General Psychiatry2019,32,2:3
