Exploring anatomy and physiology using iPad applications          下载免费PDF全文

Tandra R. Chakraborty  Deborah F. Cooperstein 《Anatomical sciences education》2018,11(4):336-345

This study examined the use of iPads with anatomy applications (apps) in the laboratory sections of the largest undergraduate course at the university, Anatomy and Physiology, serving more than 300 students. The majority of these students were nursing, exercise science/physical education and biology majors. With a student survey (student opinion) and student practicum grades as metrics, this study determined whether the introduction of this novel mobile technology improved student grades and aided the students in learning the course material. The results indicated that students’ grades improved with the introduction of the iPads, and 78% of the students reported that the iPads facilitated their ability to learn the course material. There was a positive association between frequency of app use and standardized mastery of the course material, as students who used the apps more frequently scored higher and indicated that they felt as though they had learned the material more comprehensively. Owning or having an iPad at home did not have a significant effect on the learning of the material. The general consensus by students was that iPad anatomy apps should be used frequently to better develop student understanding of the course material.

Rapid determination of erythrocyte sedimentation rate (ESR) by an electrically driven blood droplet biosensor     

Sumit Kumar  Rishi Ram  Arnab Sarkar  Sunando DasGupta  Suman Chakraborty 《Biomicrofluidics》2020,14(6)

In healthcare practice, the sedimentation rate of red blood cells (erythrocytes) is a widely used clinical parameter for screening of several ailments such as stroke, infectious diseases, and malignancy. In a traditional pathological setting, the total time taken for evaluating this parameter varies typically from 1 to 2 h. Furthermore, the volume of human blood to be drawn for each test, following a gold standard laboratory technique (alternatively known as the Westergren method), varies from 4 to 5 ml. Circumventing the above constraints, here we propose a rapid (∼1 min) and highly energy efficient method for the simultaneous determination of hematocrit and erythrocyte sedimentation rate (ESR) on a microfluidic chip, deploying electrically driven spreading of a tiny drop of blood sample (∼8 μl). Our unique approach estimates these parameters by correlating the same with the time taken by the droplet to spread over a given radius, reproducing the results from more elaborate laboratory settings to a satisfactory extent. Our novel methodology is equally applicable for determining higher ranges of ESR such as high concentration of bilirubin and samples corresponding to patients with anemia and patients with some severe inflammation. Furthermore, the minimal fabrication steps involved in the process, along with the rapidity and inexpensiveness of the test, render the suitability of the strategy in extreme point-of-care settings.  相似文献

Distributors and film critics: does it take two to Tango?     

S. Abraham Ravid  John K. Wald  Suman Basuroy 《Journal of Cultural Economics》2006,30(3):201-218

Previous literature has documented the impact of critics on audience choices of movies. We investigate three issues regarding professional critics in the motion picture industry. First we document whether and to what extent critics and their recommendations exhibit a statistical bias toward specific studios. We show that reviews by a number of critics are significantly affected by the film distributor’s identity. A second question is whether audiences are able to distinguish between biased and unbiased critics. We cannot support the view that audiences put less weight on the views of biased critics; in fact, they may listen to them more. Third, we try to characterize critics who are more prone to bias. Surprisingly, but in accord with reputation models, we find that more reputable critics may be more biased; in particular, critics based in L.A. tend to significantly prefer specific studios.

Aspirations of Indian inventors moderated by patenting experience,age and sector     

Mary Mathew  Nilanjana Bhaduri nee Chakraborty 《The Journal of High Technology Management Research》2012,23(1):71-81

In this hyper-competitive era, patents are an essential input to realizing sustainable competitive advantage. However, individual differences exist in patenting filing behavior and behaviors related to commercialization of patents. This study explores these behaviors in the context of three demographic variables. The demographic variables are patenting and commercialization experiences of inventors, age and sector. Further, aspirations of these inventors are assessed using external motivators of wealth, fame, and concern for societal welfare, and internal motivators such as pragmatism. The findings of this empirical study (n = 116) suggest that sector and age determine differences in personal internal motivators more than patent commercialization experience. Implications of the study are discussed.  相似文献

Perspective: Flicking with flow: Can microfluidics revolutionize the cancer research?     

Tamal Das  Suman Chakraborty 《Biomicrofluidics》2013,7(1)

According to the World Health Organization, cancer is one of the leading causes of death worldwide. Cancer research, in its all facets, is truly interdisciplinary in nature, cutting across the fields of fundamental and applied sciences, as well as biomedical engineering. In recent years, microfluidics has been applied successfully in cancer research. There remain, however, many elusive features of this disease, where microfluidic systems could throw new lights. In addition, some inherent features of microfluidic systems remain unexploited in cancer research. In this article, we first briefly review the advancement of microfluidics in cancer biology. We then describe the biophysical aspects of cancer and outline how microfluidic system could be useful in developing a deeper understanding on the underlying mechanisms. We next illustrate the effects of the confined environment of microchannel on cellular dynamics and argue that the tissue microconfinement could be a crucial facet in tumor development. Lastly, we attempt to highlight some of the most important problems in cancer biology, to inspire next level of microfluidic applications in cancer research.  相似文献
