Standardisation of an Ayurvedic formulation "Sanjivani Vati"
Parameswaran Sandhya,Mandar Nandan
International Journal of Green Pharmacy , 2010,
Abstract: Sanjivani vati is official in Ayurvedic formulary of India and is prescribed for the treatment of cough and fever. It is a polyherbal preparation containing ten ingredients. In this research paper, an attempt has been made to develop standardisation methods for some of the ingredients of Sanjivani vati. Quantitative estimation of tannins was done by Folin Denis method using gallic acid as standard. Embelin and Piperine were estimated by reverse phase HPLC. A standard laboratory reference sample of Sanjivani vati and two marketed samples were evaluated as per the developed method. The methods developed were validated in terms of linearity, accuracy, precision and recovery. Results indicated that only one marketed sample complied with all the standards prescribed and its content of tannin, piperine and embelin were equivalent to standard reference values.
Comparative Efficacy of Polyamine-Based Scavenger Resins  [PDF]
Krishnarao Sandhya, Bhagavathula Ravindranath
International Journal of Organic Chemistry (IJOC) , 2012, DOI: 10.4236/ijoc.2012.21012
Abstract: Polyamine-based scavenger resins containing 2, 3 and 4 nitrogen atoms have been prepared and their comparative efficacy to scavenge appropriate electrophilic chemicals (acids, acid chlorides, isocyanates and aldehydes) from solutions has been studied. As expected, the scavenging efficiency is directly proportional to the number of nucleophic nitrogens present on the resin. The results have been compared with the performance of the popular scavenger resin, namely, tris(2-aminoethyl)amine resin, to conclude that the low-cost polyamine resins now prepared can be conveniently used as effectively as the expensive commercial product.
Understanding Rolle's Theorem
REVATHY PARAMESWARAN
Mathematics Educator , 2009,
Abstract: This paper reports on an experiment studying twelfth grade students’ understanding of Rolle’s Theorem. In particular, we study the influence of different concept images that students employ when solving reasoning tasks related to Rolle’s Theorem. We argue that students’ “container schema” and “motion schema” allow for rich concept images.
Expert Mathematicians' Approach to Understanding Defintions
Revathy Parameswaran
Mathematics Educator , 2010,
Abstract: In this article I report on a study of the cognitive tools that research mathematicians employ when developing deep understandings of abstract mathematical definitions. I arrived at several conclusions about this process: Examples play a predominant role in understanding definitions. Equivalent reformulations of definitions enrich understanding. Evoked conflicts and their resolutions result in improved understanding. The primary role of definitions in mathematics is in proving theorems. And there are several stages in developing understandings of mathematical definitions (Manin, 2007; Tall & Vinner, 1981; Thurston, 1994). I also include some suggestions for pedagogy that are found in the data.
Case series of eosinophilic meningoencephalitis from South India
Parameswaran K
Annals of Indian Academy of Neurology , 2006,
Abstract: Eosinophilic meningoencephalitis (EM) is a rare type of meningoencephalitis. The objective of this report is to describe a series of EM identified in a specific geographic area over a short period of time. Materials and Methods: This series of cases are described from a neurological center in Central Kerala occuring in the period between February 2004 and June 2006. Results: During this period we had identified ten patients (eight males and two females) with EM. Their mean age was 37.1 years (range 15-60 years). Main symptomatologies were fever, severe headache, body pain, abdominal pain and arthralgia. One patient was in akinetic rigid state with coma. All patients had peripheral eosinophilia. The cerebrospinal fluid (CSF) of all patients showed eosinophilic pleocytosis. The mean CSF white cell count was 588 cells. CSF differential count showed 50-70% eosinophils. CSF glucose levels were normal but proteins were markedly raised (mean CSF protein was 180 mg/dl). MRI brain showed T2 hyperintensities diffusely in periventricular white matter in the comatose patient. Contrast enhanced CT scan of the brain was normal in others. All eight male patients gave history of eating "raw flesh of Monitor Lizard" (Iguana) some three to fourteen days prior to the onset of symptoms. There was no such history for the female patients. Considering the history of exposure and eosinophilic meningitis we suspected a meningoencephalitis with Angiostrongylus cantonensis and treated them with albendazole, steroid and other supportive measures. All of them recovered. Conclusion: Eosinophilic meningitis (EM) is a rare condition and in this locality, a CNS infection with Agiostrongylus cantonensis is highly likely. AC is a parasite in monitor lizard. Human infection occurs from consumption of uncooked flesh or blood of infected lizards. Physicians need to maintain a high index of suspicion and enquire for any exposure to uncooked meat or blood of monitor lizard when faced with EM. Specific therapy with albendazole offers excellent response.

K theory of smooth complete toric varieties and related spaces
Parameswaran Sankaran
Mathematics , 2007,
Abstract: The K-rings of non-singular complex pro jective varieties as well as quasi- toric manifolds were described in terms of generators and relations in an earlier work of the author with V. Uma. In this paper we obtain a similar description for complete non-singular toric varieties. Indeed, our approach enables us to obtain such a description for the more general class of torus manifolds with locally standard torus action and orbit space a homology polytope.
A coincidence theorem for holomorphic maps to G/P
Parameswaran Sankaran
Mathematics , 2002,
Abstract: We show that any two holomorhpic maps, not both of which are constant, from a generalized Hopf manifold to its base must have a coincidence. We prove a similar result for holomorphic maps from a generalized Calabi-Eckmann manifold.
On homeomorphisms and quasi-isometries of the real line
Parameswaran Sankaran
Mathematics , 2006,
Abstract: We show that the group of all pl-homeomorphisms of the reals having bounded slopes surjects on the group $QI({\Bbb R})$ of all quasi-isometries of ${\Bbb R}$. We prove that the following groups can be imbedded in $QI({\Bbb R})$: The group of compactly supported pl-homeomorphisms of the reals, the Richard Thompson group F, and the free group of rank the continuum.
Global health care challenge: Indian experiences and new prescriptions
Wakdikar,Sandhya;
Electronic Journal of Biotechnology , 2004,
Abstract: globally, there has been an unparalleled growth in the plant-derived medicinally useful formulations, drugs and health-care products, its market covering more than 60% products derived from plant origin. india exhibits remarkable outlook in modern medicines that are based on natural products besides traditional system of indian medicines. almost, 70% modern medicines in india are derived from natural products. medicinal plants play a central role not only as traditional medicines but also as trade commodities, meeting the demand of distant markets. ironically, india has a very small share (1.6%) of this ever-growing global market. to compete with the growing market, there is urgency to expeditiously utilize and scientifically validate more medicinally useful plants while conserving these species, which seems a difficult task ahead. this paper begins with an overview of the value of medicinal and aromatic plants and discusses its usefulness in the traditional medicines. then it briefly assesses the potential of medicinally useful plants and prospects of modern medicines and health care products derived from plant origin and based on the knowledge of alternative system of medicine in india. it thereafter concisely touches upon india’s varied biodiversity, comparative research and development strength, strong pharmaceutical manufacturing base and traditional wisdom in medicines to improve its market potential. in the conclusion, there are major recommendations to help india evolve as a major drugs and herbal based health care products leader in the world market.
