Interaction of small aromatic molecules: An ab initio studies on benzene and pyridine molecules  [PDF]
Bipul Bezbaruah, P. Hazarika, A. Gogoi, O. K. Medhi, C. Medhi
Journal of Biophysical Chemistry (JBPC) , 2011, DOI: 10.4236/jbpc.2011.21005
Abstract: The use of appropriate level of theories for studying weak interactions such as stacking of aromatic molecules has been an important aspect, since the high level methods have limitations for application to large molecules. The differences in the stacking energies of various structures are found significant for identifying the most favored stacked benzene rings and the pyridine rings. The most favored structure of benzene rings obtained from various methods are similar, and also comparable with that of reported accurate CCSD(T) method. The effect of basis set in the stacking energies of MP2 calculations is small. Thus the moderately accurate methods may be feasible for studying the stacking interactions as demonstrated for benzene and pyridine molecules.
Food Habit and Feeding Patterns of Great Indian One-Horned Rhinoceros (Rhinoceros unicornis) in Rajiv Gandhi Orang National Park, Assam, India

ISRN Zoology , 2012, DOI: 10.5402/2012/259695
Abstract: Food and feeding patterns of great Indian one-horned Rhinoceros (Rhinoceros unicornis) has been studied in Rajiv Gandhi Orang National Park. Altogether 75 species of grasses, 27 species of herbs-shrubs, 27 species of trees, and 9 species of aquatic plants species were identified as a food-plant species of Indian Rhino in the study area. Of the total 75 species of grasses, 48 species had a relative dominance of <1.0. The Saccharum spontaneum was ranked as the highest relative dominance food-plant among grasses (relative dominance value, 8.45%), while the Cyperus pilosus ranked the lowest (relative dominance value, 0.08%). Among 27 herbs-shrubs species, three had a relative dominance of <1.0. The Diplazium esculentum was ranked the highest relative dominance food plants among herbs-shrubs food plants (relative dominance value, 13.83%), while the Solanum viarum was ranked the lowest (relative dominance value, 0.66%). All tree species had a relative dominance of >1.0. The Dalbergia sissoo ranked the highest among all trees (relative dominance value, 7.94%), while the Anthocephalus cadamba ranked the lowest (value, 1.19%). Grasses constituted 86.66% of the total annual diet of Rhino, while the aquatic and woodland species constituted only 13.34% of the total annual diet. Altogether 71 plants species were identified as the Rhino food plants at Rajiv Gandhi Orang National Park. Of which, grasses constituted the highest (42 species), followed by woodland species (trees, herbs-shrubs), (20 species) and aquatic plants (9 species). The grass species Hemarthria compressa contributed a highest of 11.63%, while the aquatic plant Polygonum hydropiper was the least of 0.01% in total annual diet. Out of total 42 food-plant species, 20 grass species had no selectivity. The Hemarthria compressa was the top ranking grass species that has been selected as food by the Indian Rhino. Altogether, 36 food-plants (24 grasses, 9 woodland species, and 3 aquatic species) were identified as the staple food that constituted 83.64% of the total annual diet. Study showed that ten top ranking food plants constituted 56.44% and 20 top ranking food plants constituted 72.19% of the total annual diet. Thus, the grass species alone have enough to provide food for Indian Rhino in Rajiv Gandhi Orang National Park. Soil licking and crop depredation by the Indian Rhino were common in the fringe villages in study area. 1. Introduction Food is the primary requirement of an animal to survive and maintain its good health. Hence, the animal must acquire food that contains enough nutrients to fulfill
Leiomyoma of the nasal septum
Singh R,Hazarika P,Balakrishnan R,Gangwar N
Indian Journal of Cancer , 2008,
Abstract: Leiomyoma of nasal cavity is an extremely rare and unusual benign mass that uncommonly arises from the nasal septum. These are vascular or nonvascular masses of myogenic origin. We present a rare case of leiomyoma arising from the nasal septum and discuss its management using KTP 532 laser.
Gnathostomiasis of the anterior chamber
Barua P,Hazarika N,Barua N,Barua C
Indian Journal of Medical Microbiology , 2007,
Abstract: Ocular involvement with Gnathostoma spinigerum occurs years after the initial infection that is acquired by ingestion of poorly cooked, pickled seafood or water contaminated with third stage larvae. Here we report a case of gnathostomiasis of the left eye of a 32-year-old lady hailing from Meghalaya, India. Her vision had deteriorated to hand movement. Slit lamp examination revealed a live, actively motile worm in the anterior chamber, which was extracted by supra temporal limbal incision and visual acuity was restored.

Loa loa in the anterior chamber of the eye: A case report
Barua P,Barua N,Hazarika N,Das S
Indian Journal of Medical Microbiology , 2005,
Abstract: An unusual case of loiasis from Assam is reported here. Loa loa is a subcutaneous filarial parasite of man and is transmitted to humans by chrysops flies. The patient presented with foreign body sensation and visual disturbances of the right eye. Examination revealed a white coiled structure in the cornea.. Routine blood and other investigations were within normal limits. A live adult worm was extracted and identity was confirmed by microscopy to be Loa loa. Patient was treated with diethylcarbamazine and steroid. We found this case interesting as the worm was present in the anterior chamber - an unusual site and there were no other positive findings besides the lone worm.
Profit from Sickness: The Case of Technology-Driven Healthcare  [PDF]
Suman Hazarika, Akhil Ranjan Dutta
Advances in Applied Sociology (AASoci) , 2012, DOI: 10.4236/aasoci.2012.24031
Abstract: The increasing corporatization and growing dependence of the healthcare system on technology has brought about a radical transformation to the entire mission of the healthcare system. Based on the profit motive, the pharmaceutical and technological enterprises that hugely control the healthcare system today have so transformed the system that it has now emerged as one of the most profiteering domains. The historical tragedy is that the profit is earned over sickness. There has indeed been an attempt to generate sickness as demanded both by health care devices as well as by the pharmaceutical industries having detrimental impact on people’s right to health. Present paper, which critically questions the logic and motives of the emerging healthcare system, argues that under the contemporary neo-liberal economies, diseases and patients are objects of business interests of the largely privatized for-profit healthcare industry. Profit from these objects emerges not only through sale of drugs or cure, but also from expensive hi-tech testing and ‘treatment’ technologies. Creation of new patients by diagnosing more diseases to treat is contributed by a large medical-industrial complex today. The paper is of the view that remedies to these crises demand radical a U-turn to the system itself wherein the health care seekers rather than the health care providers would occupy the center stage.
Healthcare Technology: A Domain of Inequality  [PDF]
Suman Hazarika, Akhil Ranjan Dutta
Advances in Applied Sociology (AASoci) , 2013, DOI: 10.4236/aasoci.2013.32011
Abstract: The prevailing perception that technological development facilitates universal empowerment and transcends the social domains of discriminations is now challenged by comprehensive studies. Technology itself is a domain of inequality and it accentuates more inequality with technology gradually favoring the privileged sections and the societies. The healthcare technology, which otherwise could have brought miracle achievements in attaining universal health standards, however, has failed to do so due to the inherent inequality in access to healthcare technology. The growing dominance of monopoly houses on healthcare technology and marginalization of indigenous health technology makes access to technology with a new domain of inequality. With comprehensive empirical data, the present paper investigates into this domain of inequality and argues that a move towards global well being demands a radical restructuring of the global domain of healthcare technology.

Proyecciones (Antofagasta) , 2012,
Abstract: Recently in [22], Mursaleen introduced the concept of statistical convergence in random 2-normed spaces. In this paper, we define and study the notion of lacunary An-statistical convergence and lacunary An-statistical Cauchy sequences in random 2-normed spaces using la-cunary density and prove some interesting theorems.
Generalized pustular psoriasis of pregnancy successfully treated with cyclosporine
Hazarika Debeeka
Indian Journal of Dermatology, Venereology and Leprology , 2009,
Abstract: Two multigravidae aged 27 and 29 years, with previous uneventful pregnancies, second being psoriatic, reported at 24 and 28 weeks of pregnancies, with generalized pustular lesions. Laboratory findings, including serum calcium were normal. Ultrasonography showed normal fetal growth. Histopathology confirmed pustular psoriasis. Patients were put on cyclosporine 3 mg/ kg weight/ day after failure of an initial systemic steroid. Blood pressure, pulse, and fetal heart sounds were recorded every 12 hours, and ultrasonography and blood parameters, biweekly. Cyclosporine was tapered and stopped after delivery of two healthy babies at 38 weeks. We conclude that cyclosporine can be an option in the management of pustular psoriasis of pregnancy or psoriasis with pustulation in pregnancy.
