Pattern of Syringomyelia in Presumed Idiopathic and Congenital Scoliosis
Mohanty Simanchal Prosad,Kanhangad Madhava Pai,Saifuddin Sibin,Narayana Kurup Jayakrishnan K. 대한척추외과학회 2021 Asian Spine Journal Vol.15 No.6
Study Design: Retrospective study. Purpose: This study was undertaken to compare the patterns of syringomyelia in patients with presumed idiopathic and congenital scoliosis. Overview of Literature: The incidence of neuraxial anomalies presenting as idiopathic scoliosis ranges from 2% to 14%; the common ones are idiopathic syringomyelia (IS) and Chiari malformation type 1 (CM1) with syringomyelia. Some authors have speculated that scoliosis is caused by the asymmetrical compression of anterior horn cells by a syrinx, which causes an imbalance of the trunk musculature. In congenital scoliosis, syringomyelia is the second commonest cord anomaly, and the deformity progression depends upon the underlying vertebral abnormality, the location of the abnormality, and the age of patient, and is independent of the intraspinal anomaly. Methods: We analyzed the radiological records of 44 consecutive patients with scoliosis and syringomyelia. Of these 44 patients, 13 had IS, 12 had CM1, and 19 had congenital scoliosis. The radiographs were evaluated to determine the curve magnitude, sagittal alignment, side of convexity, and type of vertebral anomaly, if any. T1- and T2-weighted magnetic resonance imaging of the whole spine was analyzed to determine the presence of craniovertebral anomalies, syrinx length, syrinx diameter, and syrinx-cord ratio (SCR). Results: The frequency of left convex curves was 26.1%, with no significant differences across the three groups. The mean length of the syrinx was 7.2±4.9 vertebral levels, and the mean SCR was 0.39±0.2. The mean syrinx length was significantly higher in patients with CM1 and IS, compared to patients with congenital scoliosis. The mean SCR was highest in patients with CM1. In congenital scoliosis, syringomyelia was seen most frequently in patients with a failure of formation, and 63.2% had concomitant cord anomalies. Conclusions: Syrinxes were smaller in size and length in patients with congenital scoliosis, and are distinct from those seen in IS and CM1.
Role of Dental Institutions in Tobacco Cessation in India: Current Status and Future Prospects
Mohanty, Vikrant Ranjan,Rajesh, Guru Raghavendran,Aruna, D.S. Asian Pacific Journal of Cancer Prevention 2013 Asian Pacific journal of cancer prevention Vol.14 No.4
Tobacco abuse is a major preventable cause of premature death and disease, including various cancers. The Global Adult Tobacco Survey India (GATS) 2009-10 revealed that more than one-third of adults use tobacco in one form or the other. Nearly two in five smokers and smokeless tobacco users made attempts to quit the habit in the past 12 months. Tobacco dependence is a chronic condition characterized by susceptibility of relapse over years. It can be well handled by sustained professional support from health care providers mainly through behavioral counseling and pharmacotherapy. Dental professionals can play a pivotal role in diagnosing and effectively managing tobacco dependence. Dental Institutions have rapidly grown in last two decades across the country and so has the curriculum been adapted to improve student competencies to accommodate changing disease patterns and technological advances, but not in regard to tobacco cessation. Untapped dental manpower like undergraduates, dental hygienists and other paramedical staff need effective training to be more penetrative. The present review paper explores the potential role of dental training institutions and recommends various approaches to counter public health jeopardy of tobacco related diseases.
A Strong Designated Verifiable DL Based Signcryption Scheme
Mohanty, Sujata,Majhi, Banshidhar Korea Information Processing Society 2012 Journal of information processing systems Vol.8 No.4
This paper presents a strong designated verifiable signcryption scheme, in which a message is signcrypted by a signcryptor and only a specific receiver, who called a "designated verifier", verifies it using his own secret key. The scheme is secure, as an adversary can not verify the signature even if the secret key of the signer is compromised or leaked. The security of the proposed scheme lies in the complexity of solving two computationally hard problems, namely, the Discrete Logarithm Problem (DLP) and the Integer Factorization Problem (IFP). The security analysis of the scheme has been done and it is proved that, the proposed scheme can withstand an adaptive chosen ciphertext attack. This scheme can be very useful in organizations where there is a need to send confidential documents to a specific recipient. This scheme can also be applicable to real life scenarios, such as, e-commerce applications, e-banking and e-voting.
Stabilization of expansive soil using industrial wastes
Mohanty, Soumendra K.,Pradhan, Pradip K.,Mohanty, Chitta R. Techno-Press 2017 Geomechanics & engineering Vol.12 No.1
Swelling and shrinkage characteristics of expansive fine grained soil cause volumetric changes followed by distress and damage to the structures. Soil stabilization can be explained as the alteration of the soil properties by chemical, mechanical or any other means in order to enhance the engineering properties of the soil. Utilization of industrial wastes in soil stabilization is cost effective and environment friendly. This paper presents an experimental study on stabilization of expansive soil using industrial wastes, viz. fly ash and dolochar. The paper includes the evaluation of engineering properties like unconfined compressive strength and California bearing ratio (CBR) of expansive soil collected from Balasore district of Odisha stabilized with fly ash and dolochar in different proportions and to predict the influence of these additives on engineering properties and strength characteristics of expansive soil. Both fly ash and dolochar were found to increase the CBR and decrease many index properties such as liquid limit, plastic limit, plasticity index, swelling index and UCS, thus enhancing the strength parameters of expansive soil.

In this study, we have integrated a rice genome-scale metabolic network and the transcriptome of a drought-tolerant rice line, DK151, to identify the major transcriptional regulators involved in metabolic adjustments necessary for adaptation to drought. This was achieved by examining the differential expressions of transcription factors and metabolic genes in leaf, root and young panicle of rice plants subjected to drought stress during tillering, booting and panicle elongation stages. Critical transcription factors such as AP2/ERF, bZIP, MYB and NAC that control the important nodes in the gene regulatory pathway were identified through correlative analysis of the patterns of spatio-temporal expression and cis-element enrichment. We showed that many of the candidate transcription factors involved in metabolic adjustments were previously linked to phenotypic variation for drought tolerance. This approach represents the first attempt to integrate models of transcriptional regulation and metabolic pathways for the identification of candidate regulatory genes for targeted selection in rice breeding.
Assessment of seasonal variations in water quality of Brahmani river using PCA
Mohanty, Chitta R.,Nayak, Saroj K. Techno-Press 2017 Advances in environmental research Vol.6 No.1
Assessment of seasonal changes in surface water quality is an important aspect for evaluating temporal variations of river pollution due to natural or anthropogenic inputs of point and non-point sources. In this study, surface water quality data for 15 physico-chemical parameters collected from 7 monitoring stations in a river during the years from 2014 to 2016 were analyzed. The principal component analysis technique was employed to evaluate the seasonal correlations of water quality parameters, while the principal factor analysis technique was used to extract the parameters that are most important in assessing seasonal variations of river water quality. Analysis shows that a parameter that is most important in contributing to water quality variation for one season may not be important for another season except alkalinity, which is always the most important parameters in contributing to water quality variations for all three seasons.

Despite the rising demand for lithium-ion batteries and their widespread acceptance, recycling and repurposing end-of-life lithium-ion battery materials is still a work in progress. This will help mitigate the dependence on raw materials and risks of shortage while promoting a circular economy. The present work addresses a hydrometallurgical process to recover Mn from spent LiMn2O4 using sulphuric acid as a lixiviant and Na-D2EHPA as extractant. Effects of various leaching parameters have been studied and the pregnant leach solution has been generated using 1 mol/L H2SO4 with 6% H2O2 at a pulp density of 10 g/L, maintaining the temperature at 30°C at 450 rpm for 1 hour which contained 2.52 g/L Mn and 0.545 g/L of Li. The PLS was subjected to separation using solvent extraction method taking 70% saponified di-(2-ethylhexyl) phosphoric acid (D2EHPA) as extractant. The McCabe-Thiele plot suggested two theoretical stages at O:A ratio of 1:1 using 0.3 mol/L Na-D2EHPA with 99.94% extraction of Mn and 10.2% co-extraction of Li. The co-extracted lithium was removed by scrubbing with MnSO4 solution. The loaded organic containing 2.574 g/L Mn was stripped using 10% H2SO4 at two stages at O: A ratio of 1.5:1 and enriched the concentration of manganese 1.5 times in the stripped solution.
