Effect of Infliximab Therapy in Functional Improvement in Patients with Ankylosing Spondylitis
No full textABSTRACT
Introduction
Ankylosing spondylitis (AS), one of the spondyloarthropathies predominantly affecting younger people, is notorious for morbidity with pain, functional impairment, and disability. Infliximab, a chimeric tumor necrosis factor (TNF) alpha inhibitor, has been proven as a safe and effective biologic in respect to improvement in clinical and radiological parameters in AS. This study is a humble attempt to look for disability limitations by infliximab therapy in patients with AS.
Aims and objectives
To look for functional improvement in AS patients treated with Infliximab in comparison with control group who were treated conservatively.
Materials and methods
A randomized controlled trial was done in the Department of Physical Medicine and Rehabilitation, Institute of Postgraduate Medical Education & Research and Seth Sukhlal Karnani Memorial Hospital, Kolkata, West Bengal, India, from December 2015 to May 2017, recruiting 20 AS patients who fulfilled the Assessment of SpondyloArthritis International Society (ASAS) criteria and had significant functional limitation. After Ethics Committee clearance, two groups were made randomly. Both groups I and II were included in the rehabilitation program. Group I, in addition, received injection infliximab on days 0, 14, and 42. Assessment by the Bath ankylosing spondylitis functional index (BASFI) and visual analog scale (VAS) for lower back pain was done before intervention and 2, 6, 12 weeks after initiation of treatment.
Results
Statistically significant positive outcome difference was seen in the first group in comparison with control group based on both outcome parameters.
Conclusion
Infliximab is a safe and highly efficacious biologic therapy in limiting disability in AS patients when treated early.

fiction”. Final Assignment.The undergraduates program of Indonesian Literature, Diponegoro University. Ambar Ekamawati. 2017. Mentor: Drs. Mulyo Hadi Purnomo, M. Hum. Dan Laura Andri R. M., S. S, M. Hum.
Incognito Novel is one of the novels by Windhy Puspitadewi which is a fantasy adventure novel of the three teenagers who travel the time. Windhy Puspitadewi make a surreal story, against the realist that is present in the flow of new and events outside the boundaries of logic. Formal object in this study using flow which thus provides the fantasy in the story.The tragedy that happened in the adventure story was experienced Carl, Erik, and Sisca in the parallel world is a supernatural event.
This study aims to reveal the supernatural elements that build up in the flow of events of the adventure and fantasy Incognito novel by Windhy Puspitadewi. The Theory in this study using of Struktural theory by describing the facts and data in the text then used as a foothold for analysis. The stage of data analysis is done by collecting data obtained, after which is analyzes with descriptive analytical aspect of the stage plot, conflict, and events that build the novel approach of fantasy fiction as a cornerstone in analyzing the elements that build up in the Incognito Novel.
The result of this analysis is the stage of the groove adventure and supernatural elements that build Incognito Novel in the form Uncanny and fantasy. Supernatural elements that is found a picture of the raity of the real world to the world of the past in the form of the fantasy. Things are hard earned and beyond the limits of logic into the form author in violation of existing conventions to create another world.

Probing Aromaticity in Intermediate and Transition States along with Non-Traditional Reaction Paths
No full textFor chemists, the tryst with aromaticity began with the dream and subsequent works
by Kekule. Gradually with the advent of quantum chemistry, aromaticity was given a
strong theoretical foundation, the Huckel's rule being the most prominent of them.
Yet the problem of quantification of aromaticity remained unresolved. This problem
was interfaced with the phenomenon of magnetically induced ring current and
quantification of aromaticity was linked with NMR chemical shifts. Nuclear
Independent Chemical Shift (NICS methods) and more recently Magnetically
Induced ring Current density (MICD) have been used to quantify aromaticity. NICS
has been employed majorly, due to its computational simplicity, to investigate the
implication of aromaticity in chemical reactions, by quantifying aromaticity of
transition states, in pericyclic reaction in particular. MICD has seen some very few
recent applications. Chances for isolation of transition states are nil and aromaticity
of intermediates of chemical reactions have rarely been investigated. The work
presented in this thesis is concerned with the investigation of aromaticity property
for intermediates involved in the non-traditional mechanistic pathways of simple
chemical reactions. This thesis is composed _of two major types of work/findings.
Firstly the attempt has been to establish unusual mechanistic pathways for simple
chemical reactions. This thesis reconciles different facets of quantum chemistry like
static computation, for structure determination and property calculation, coupled
with the reaction dynamics, in condensed phase, under one common roof. Secondly,
computation and quantification of aromaticity, using NICS and MICD in particular,
for intermediates along the non-traditional reaction paths has been addressed. The
chemical reactions investigated span from oxidation reaction and photo-redox
process to excited state photochemical reaction. Four-center-two-electron (4c-2e) bond is a more recently discovered bonding
pattern. Aromaticity of paradigmatic cases of 4c-2e bond like TCNE2 (2-) and foursulfur- two-electron bonded complex have been thoroughly investigated. An unusual 4c-2e bonded intermediate has been found in the mechanistic pathway for oxidation of hydrazine. The aromaticity of this intermediate has also been investigated. Excited state aromaticity has been addressed using MICD technique for the first time. While investigating the photo-dissociation of N2 from 5-Phenyl- Tetrazole, an interlink between photo-induced charge transfer and drastic changes in excited-state aromaticity has been established.
Additionally, a prebiotic photo-redox reaction has been studied. Dimerization of two dipole-bound-anions was found to be a crucial step in the mechanism for the photoreduction process. Despite the coulombic repulsion, the dimerization was found to be facile due to the gain in the aromatic stabilization of the dianionic intermediate formed.Research was carried out under the supervision of Prof. Ankan Paul of RCAMOS under SCS [School of Chemical Sciences]Research conducted under CSIR fellowship research gran
Simulating Distributed Wireless Sensor Networks for Edge-AI
No full textThis paper presents the simulation of distributed wireless sensor networks (WSNs) consisting of autonomous mobile nodes that communicate, with or without a central/root node, as desired for edge artificial intelligence (edge-AI). We harness the high-resolution and multidimensional sensing characteristics of IEEE 802.15.4 standard and Routing Protocol for Low-Power and Lossy Networks (RPL) to implement dynamic, asynchronous, event-driven, targeted communication in distributed WSNs. We choose Contiki-NG/Cooja to simulate two WSNs, one with and the other without a root node. The simulations are assessed on the network Quality of Service (QoS) parameters such as throughput, network lifetime, power consumption, and packet delivery ratio. The simulation outputs show that the sensor nodes at the edge communicate successfully with the specific targets responding to particular events in an autonomous and asynchronous manner. The performance is slightly degraded when using the RPL WSN with a root node. This work shows how to simulate and evaluate distributed WSNs using the Cooja simulator which would be useful for designing such networks for edge-AI applications, such as visual surveillance, monitoring in assisted living facilities, intelligent transportation with connected vehicles, automated factory floors, immersive social media experience, and so on
Performance Comparison of Cosine, Haar, Walsh-hadamard, Fourier and Wavelet Transform for Shape based Image Retrieval Using Fuzzy Similarity Measure
No full textAbstractShape is one of the most important features in Content Based Image Retrieval (CBIR). When a shape is used as feature, edge detection might be the first step of feature extraction. Invariance to the different transformations like translation, rotation, and scale is required by a good shape representation. In this paper a performance comparison is done on various image transforms like Wavelet transform, Fourier transform, Haar transform, Walsh-Hadamard transform and discrete cosine transform using a fuzzy similarity measure. It is seen that according to retrieval performance Wavelet transform gives the best result among the other mentioned transforms. It has higher recall and precision values and higher crossover point
