Prevalence of diabetes mellitus, a chronic metabolic disease characterized by hyperglycemia, is growing worldwide. The majority of the cases belong to type 2 diabetes mellitus (T2DM). Globally, India ranks second in terms of diabetes prevalence among adults. Currently available classes of therapeutic agents are used alone or in combinations but seldom achieve treatment targets. Diverse pathophysiology and the need of therapeutic agents with more favourable pharmacokinetic-pharmacodynamics profile make newer drug discoveries in the field of T2DM essential. A large number of molecules, some with novel mechanisms, are in pipeline. The essence of this review is to track and discuss these potential agents, based on their developmental stages, especially those in phase 3 or phase 2. Unique molecules are being developed for existing drug classes like insulins, DPP-4 inhibitors, GLP-1 analogues; and under newer classes like dual/pan PPAR agonists, dual SGLT1/SGLT2 inhibitors, glimins, anti-inflammatory agents, glucokinase activators, G-protein coupled receptor agonists, hybrid peptide agonists, apical sodium-dependent bile acid transporter (ASBT) inhibitors, glucagon receptor antagonists etc. The heterogeneous clinical presentation and therapeutic outcomes in phenotypically similar patients is a clue to think beyond the standard treatment strategy.  相似文献

Pragati Priyadarshinee  Rakesh D. Raut  Manoj Kumar Jha  Sachin S. Kamble 《The Journal of High Technology Management Research》2017,28(2):221-245

The purpose of this research article is to identify the critical success criteria/factors that affect the cloud computing adoption and examine structure, reliability and validity of the criteria in the SMEs industry. This study considers nine types of criteria/factors with fifty-one sub-criteria, which have somewhat previously been used, and creates a ranking model that offers decision makers to measure the prior implementation of cloud computing adoption. A questionnaire-based survey research was used to collect data from 110 firms belonging to the SMEs industry in India. In this paper, the data collected was analysed by an integrated approach. Firstly, an Analytic Hierarchy Process approach was applied to find the significant fact of each criterion as the assessable indices of the cloud computing adoption. Secondly, an Exploratory Factor Analysis and Confirmatory Factor Analysis were used to examine structure, reliability and validity of the criteria. The data was tabulated in a Microsoft Excel sheet and then imported in SPSS (Statistical Package for the Social Sciences version 20) for analysis. The findings discovered that ‘Security and Privacy’, ‘Organizational Risk’, ‘Sharing and Collaboration’, ‘Confidentiality’, and ‘Integrity’ have a major effect on the adoption of cloud computing. The research was conducted in the SMEs industry in India, which may limit the generalizability of the findings. The findings and recommendations offer cloud computing service providers as well as users with a better understanding of what affects the cloud computing adoption feature, with a relevant understanding of the current scenario. The research aided in the application of the new technology of cloud computing adoption in the SMEs industry in India through the use of a wide range of criteria. The findings also help organizations study their information technology investments when applying cloud computing.  相似文献   

Bridges Between Cultural and Digital Worlds in Revolutionary Egypt     

Ramesh Srinivasan 《The Information Society》2013,29(1):49-60

Networks are both imagined and directly experienced. While most people have trouble concretely explaining what networks are and how they structure our world, very few doubt their prominence in an increasingly globalized world where information moves at a dizzying pace. Networks speak to the link between the local and global—linking an event in a small village in Tunisia to the evening news in London. Yet they bind peoples and ideas not only across distance, but also in proximity. How are such networks imagined by peoples across dimensions of class, religion, gender, and generation in the dynamic environment that is revolutionary Egypt today? This article presents initial findings from initial ethnographic and interview-focused fieldwork conducted with Egyptians across a range of demographics. It presents insights around how technological, institutional, and human networks coordinate to present convergent and divergent actions, insights that shape an ever-changing Egyptian political reality.  相似文献   

Robust sensor fault estimation scheme for satellite attitude control systems   总被引：1，自引：0，他引：1  

Jian Zhang  Akshya Kumar SwainSing Kiong Nguang 《Journal of The Franklin Institute》2013

The present paper proposes two new schemes of sensor fault estimation for a class of nonlinear systems and investigates their performances by applying these to satellite control systems. Both of the schemes essentially transform the original system into two subsystems (subsystems 1 and 2), where subsystem-1 includes the effects of system uncertainties, but is free from sensor faults and subsystem-2 has sensor faults but without any uncertainties. Sensor faults in subsystem-2 are treated as actuator faults by using integral observer based approach. The effects of system uncertainties in subsystem-1 can be completely eliminated by a sliding mode observer (SMO). In the first scheme, the sensor faults present in subsystem-2 are estimated with arbitrary accuracy using a SMO. In the second scheme, the sensor faults are estimated by designing an adaptive observer (AO). The sufficient condition of stability of the proposed schemes has been derived and expressed as a linear matrix inequality (LMI) optimization problem and the design parameters of the observers are determined by using LMI techniques. The effectiveness of the schemes in estimating sensor faults is illustrated by considering an example of a satellite control system. The results of the simulation demonstrate that the proposed schemes can successfully estimate sensor faults even in the presence of system uncertainties.  相似文献   

Where Information Society and Community Voice Intersect     

Ramesh Srinivasan 《The Information Society》2013,29(5):355-365

Information and communication technology (ICT) development initiatives have begun to acknowledge the power and importance of cultural and community-focused belief systems. Yet the vast majority of such initiatives tend to preidentify developmental goals that communities hold. Paulo Freire's writings have influenced development initiatives by introducing the possibility of working with communities to orient projects. While these “participatory” initiatives have involved soliciting community feedback relative to a research project whose goals were formulated in the university or development institution, they do not go far enough to harness actual visions held by communities. It is important to conceptualize a model and methodology of engaging communities to develop and articulate their own goals of information access and ultimately, an indigenous approach toward cultural, political, and economic aspects of development. This approach holds promise to sustain communities within a return on the investment and efforts of the researcher or institution. This article closes by describing a current initiative in Southern India that reflects the described methodology.  相似文献   

Correlation of Cord Blood Lipid Heterogeneity in Neonates with Their Anthropometry at Birth     

Chandrika D. Nayak  Vaibhav Agarwal  Dinesh M. Nayak 《Indian journal of clinical biochemistry : IJCB》2013,28(2):152-157

Objective: Fetus with intrauterine stress may exhibit programmed changes that can alter its metabolism and bear severe risk for diseases in adult life. The current study was designed to assess the correlation between cord blood lipid profile with the anthropometric data in neonates. Materials and methods: 146 newborn babies born at Dr. T M A Pai Hospital, Udupi were screened and their birth weight, length, head circumference and abdominal circumference were noted at birth. Umbilical cord blood samples were analyzed for total cholesterol, triglycerides (TG), high density lipoprotein (HDL) and low density lipoprotein (LDL). Infants were also grouped further based on gestational age (GA) and sex-adjusted birth weight percentiles into three groups i.e. Small for gestational age (SGA), Appropriate for gestational age (AGA) and Large for gestational age (LGA) for comparison of their lipid profiles. Inclusion criteria were normal fetal heart rate at birth and an APGAR score >7. Statistical significance of relation between lipid profile and anthropometry was done using ANOVA and Pearson correlation coefficient. Results: Triglycerides were significantly higher in babies with higher ponderal index (PI) than those with lower PI (P = 0.011). The TG level of SGA babies were significantly higher as compared to AGA group (P = 0.001). The LDL levels in neonates with higher abdominal circumference were significantly lower than those with lower AC (P = 0.019). Mean HDL levels were higher in neonates with larger AC, but not statistically significant. Maternal BMI had no influence on neonates’ lipid profile. Conclusion: Abnormal intrauterine milieu created by maternal changes during gestation may bear a profound impact on lipid metabolism in neonates, which may account for their differences in lipid profile and anthropometry at birth.  相似文献

I CARE: Development and Evaluation of a Campus Gatekeeper Training Program for Mental Health Promotion and Suicide Prevention     

Marian Reiff  Meeta Kumar  Batsirai Bvunzawabaya  Soumya Madabhushi  Alaina Spiegel  Benjamin Bolnick 《Journal of College Student Psychotherapy》2019,33(2):107-130

Addressing the need for suicide prevention on campus, I CARE training, developed and facilitated by counseling center clinicians, trains students, staff, and faculty to provide support to students experiencing distress or mental health problems. We assessed its impact using a mixed-methods approach. Quantitative analyses demonstrated significant increases in knowledge of intervention skills and readiness to intervene from pretraining to posttraining. Knowledge and readiness remained significantly higher than preworkshop for the entire follow-up evaluation period, extending 15 months posttraining. Qualitative analyses revealed the value of experiential activities and emotional processing in increasing participants’ comfort and preparedness to intervene in challenging situations.  相似文献   

Effect of processing parameters on the electromagnetic radiation emission during plastic deformation and crack propagation in copper-zinc alloys     

KUMAR Rajeev  MISRA Ashok 《浙江大学学报(A卷英文版)》2006,7(11):1800-1809

INTRODUCTION The physics of plastic deformation and crack propagation at atomic level is complex but is essential for the development of new materials. This requires an understanding of the atomic level phenomena associated with the plastic deformation. In this con- text, emission of electromagnetic radiation (EMR) during plastic deformation and crack propagation in metals and alloys, and generation of transient mag- netic fields during crack initiation in ferromagnetic materials are rep…  相似文献
