Cytomorphological features of Hürthle cell carcinoma: A report of two cases with review of literature
Mardi Kavita,Gupta Neelam,Sharma Sudarshan,Negi Lalita
Journal of Cytology , 2010,
Abstract: The use of the term "Hürthle cell neoplasm" as the gold standard should be discouraged as it makes evaluating these lesions more confusing. Recently, a number of studies have been conducted to define criteria that are more specific for Hürthle cell carcinoma (HCC). We herein report two cases of HCC of thyroid which were accurately diagnosed preoperatively using various cytological features described in the recent studies. A review of the literature is also presented.
Will Mobile Learning Bring a Paradigm Shift in Higher Education?

Education Research International , 2011, DOI: 10.1155/2011/528495
Abstract: In the light of technology-driven social change that creates new challenges for universities, this paper considers the potential of mobile learning as a subset of e-learning to effect a paradigm shift in higher education. Universities face exponential growth in demand for higher education, significant decreases in government funding for education, a changing in understanding of the nature of knowledge, changing student demographics and expectations, and global competition. At the same time untethered mobile telephony is connecting large numbers of potential learners to communications networks. A review of some empirical literature on the current status of mobile learning that explores alternatives to help universities fulfil core functions of storage, processing, and disseminating knowledge that can be applied to real life problems, is followed by an examination of the strengths and weaknesses of increased connectivity to mobile communications networks to support constructivist, self-directed quality interactive learning for increasingly mobile learners. This paper also examines whether mobile learning can align the developing technology with changing student expectations and the implications of such an alignment for teaching and institutional strategies. Technologies considered include mobile computing and technology, wireless laptop, hand-held PDAs, and mobile telephony.
LESSONS IN ENGAGEMENT FROM A MALAY CLASSIC: THE TRANSLATION OF SYAIR SITI ZUBAIDAH PERANG CHINA
Lalita Sinha
Kajian Malaysia , 2010,
Abstract: Poetry has always played an important role in sustaining languages, as well as in conveying both the "outward" or literal and the "inward" or hidden meaning of words. The classic poem from the oral tradition of the Malay world, Syair Siti Zubaidah Perang China, conveys the nature of relationships between different cultures and traditions. One aspect of this relationship is the apparent conflict and war between the people of Kembayat Negara (or Malay-Muslims) and those of China (the Chinese tradition). However, in the process of translation of the text from Malay to English, a harmonious engagement between the Malay and the Chinese cultures has been unravelled. The contention is that through a hermeneutical reading of the text, and through observation of the exacting demands of literary translation, rich reflections of acceptance of "the other" are found, at a level that might otherwise have remained hidden. By revealing the meanings beyond the apparent theme of war and conflict, this paper offers a model for the translation of classicalMalay poetry.

Exponential growth in the demand for higher education, significant decreases in government funding for education, the changing nature of knowledge, changing student demographics and expectations, and global competition [1] in the provision of higher education and rapid advances in information and communications technologies demand a reexamination of how universities fulfil their core functions of storage, processing, dissemination, and application of knowledge to real-life problems [2, 3]. The nature of paradigms is discussed here from the perspective of Thomas Kuhn’s definition. According to Kuhn a paradigm is “what members of a scientific community, and they alone, share” [4, page 294] and “when paradigms change, the world itself changes with them” [5, page 110]. The inference is that paradigms shift when a society or community as a whole accept and practice the changes it brings. Over the ages universities have undergone many conceptual paradigm shifts in what and how they teach and to whom. Medieval theological elitist universities became modern industrial universities. Emerging virtual universities are attempts by

Golden Research Thoughts , 2013, DOI: 10.9780/22315063
Abstract: Every country governed by constitutionalism is bound to follow the principles and rules made by the fundamental document of the country. Our constitution embodies parliamentary form of government based on Westminster (British) model. Under this form the council of ministers is collectively responsible to the Lok Sabha. They hold office only if the majority in Lok Sabha supports. And none of the minister is suppose to express his individual view inconsistent with party policy. In parliamentary democracy the mandate to rule the state is given not to any individual but to a particular party. When any individual secure votes because of his allegiance to political party and after winning if he gives up the membership of that party or become disloyal to then should there be any penalty for those defectors. Or once a person gets elected as an independent candidate, the mandate of the voters is that he should remain independent throughout his tenure in the house and under no circumstances he should join any political party. This policy of aaya ram and gaya ram followed by some of the leaders under lust for post and power is strictly undertaken by our constitution in tenth schedule titled as to disqualification on ground of defection popularly known as anti-defection law. The paper seeks to examine the law on defection with special reference to the role of speaker in context of judicial review.
Antioxidant and Antibacterial Activities in the Leaf Extracts of Indian Borage (Plectranthus amboinicus)  [PDF]
Praveena Bhatt, Pradeep S. Negi
Food and Nutrition Sciences (FNS) , 2012, DOI: 10.4236/fns.2012.32022
Abstract: The different solvent extracts of the leaves of Plectranthus amboinicus were evaluated for their antioxidant and anti-bacterial properties. The ethyl acetate extract of the leaves which had the highest polyphenolic content showed an appreciable DPPH radical scavenging activity as well as total antioxidant capacity as compared with extracts obtained using hexane, acetone, methanol, hydroalcohol and freeze dried form. The acetone extract of the leaves which had the second highest polyphenolic content showed appreciable antibacterial activity with least MIC values against the tested foodborne pathogens namely Staphylococcus aureus, Bacillus cereus, Escherichia coli and Yersinia enterocolitica. The findings indicated the potentiality of ethyl acetate and acetone extract of the leaves of Indian borage for use as biopreservatives as they showed high antioxidant and antibacterial activities.

The “Bedi-IMA Buttress”: Reinforcement of the Bronchial Stump with a Pedicled Internal Mammary Artery Buttress in Diabetic Patients after Lung Resection  [PDF]
Harinder Singh Bedi, Kamal Negi
World Journal of Cardiovascular Surgery (WJCS) , 2014, DOI: 10.4236/wjcs.2014.412032
Abstract: Objective: The development of a bronchopleural fistula is a devastating complication after lung resection. We describe a new method of buttressing the closure of the stump in diabetic patients using a pedicled internal mammary artery buttress flap to avoid a bronchopleural fistula. Methods: An internal mammary pedicled flap was used in 14 diabetic patients of lung resection to cover the bronchial stump. Results: The flap of viable vascularized muscle mass gave an excellent coverage of the bronchial stump. All patients recovered well with no bronchopleural fistula. Conclusions: We recommend this technique as a method of buttressing the bronchial stump in cases of lung resection, as the internal mammary artery is easily available and its use is not associated with any side effects.

Journal of the Indian Society of Pedodontics and Preventive Dentistry , 2010,
Abstract: Early orthodontic interventions are often initiated in the developing dentition to promote favorable developmental changes. Interceptive orthodontic can eliminate or reduce the severity of a developing malocclusion, the complexity of orthodontic treatment, overall treatment time and cost. Premature loss of deciduous tooth or teeth can often destroy the integrity of normal occlusion. There are many space regaining and maintaining devices mentioned in literature. In this article, I present a simple space regaining method by a piece of nickel titanium (NiTi) wire bonded between the teeth in active loop form, and the unique shape memory property of NiTi wire will upright or move the teeth and the lost space can be regained easily.
Effect of Calcium Ion Removal, Ionic Strength, and Temperature on the Conformation Change in Calmodulin Protein at Physiological pH

Journal of Biophysics , 2014, DOI: 10.1155/2014/329703
Abstract: The response of the calmodulin (CaM) protein as a function of calcium ion removal, ionic strength, and temperature at physiological pH condition was investigated using classical molecular dynamics simulations. Changing the ionic strength and temperature came out to be two of the possible routes for observing a conformation change in the protein. This behavior is similar to the conformation change observed in our previous study where a change in the pH was observed to trigger a conformation change in this protein. In the present study, as the calcium ions are removed from the protein, the protein is observed to acquire more flexibility. This flexibility is observed to be more prominent at a higher ionic strength. At a lower ionic strength of 150?mM with all the four calcium ions intact, the N- and C-lobes are observed to come close to a distance of 30?? starting from an initial separation distance of 48??. This conformation change is observed to take place around 50?ns in a simulation of 100?ns. As a second parameter, temperature is observed to play a key role in the conformation change of the protein. With an increase in the temperature, the protein is observed to acquire a more compact form with the formation of different salt bridges between the residues of the N- and the C-lobes. The salt bridge formation leads to an overall lowering of the energy of the protein thus favoring the bending of the two lobes towards each other. The improper and dihedral terms show a significant shift thus leading to a more compact form on increasing the temperature. Another set of simulations is also performed at an increased temperature of 500?K to verify the reproducibility of the results. Thus a set of three possible alterations in the environmental conditions of the protein CaM are studied, with two of them giving rise to a conformation change and one adding flexibility to the protein. 1. Introduction Proteins are one of the most important parts present inside the eukaryotic cells. One such protein named calmodulin is well known for its key role as a calcium ion carrier inside these cells [1]. This protein helps in various physiological processes inside these cells by activating different enzymes of various types [2]. Mainly it acts as a calcium ion receptor inside the calcium signaling pathways of the cells [1]. The protein is also known for its capability that it can bind to a bulk of other proteins or small organic compounds very well. Structurally CaM can be found in both the free and bound forms as reported in [2, 3]. These forms are defined depending on the
