Pattern recognition is a task of searching particular patterns or features in the given input. The data mining, computer networks, genetic engineering, chemical structure analysis, web services etc. are few rapidly growing applications where pattern recognition has been used. Graphs are very powerful model applied in various areas of computer science and engineering. This paper proposes a graph based algorithm for performing the graphical symbol recognition. In the proposed approach, a graph based filtering prior to the matching is performed which significantly reduces the computational complexity. The proposed algorithm is evaluated using a large number of input drawings and the simulation results show that the proposed algorithm outperforms the existing algorithms.

The graph can contain huge amount of data. It is heavily used for pattern recognition and matching tasks like symbol recognition, information retrieval, data mining etc. In all these applications, the objects or underlying data are represented in the form of graph and graph based matching is performed. The conventional algorithms of graph matching have higher complexity. This is because the most of the applications have large number of sub graphs and the matching of these sub graphs becomes computationally expensive. In this paper, we propose a graph based novel algorithm for fingerprint recognition. In our work we perform graph based clustering which reduces the computational complexity heavily. In our algorithm, we exploit structural features of the fingerprint for K-means clustering of the database. The proposed algorithm is evaluated using realtime fingerprint database and the simulation results show that our algorithm outperforms the existing algorithm for the same task.

We describe a case of 42-year-old female presenting with abdominal pain associated with loss of weight and fever for 8 mo. On evaluation she had gross hepatomegaly with raised alkaline phosphatase and raised GGT levels with normal transaminases and bilirubin. On imaging she had diffuse enlargement of liver with heterogeneous contrast uptake in liver. Her viral marker and autoimmune markers were negative. Liver biopsy depicted massive deposition of amyloid in peri-sinusoidal spaces which revealed apple green birefringence on polarizing microscopy after Congo red staining. Cardiac and renal evaluation was unremarkable. Abdominal fat pad and rectum biopsy was negative for amyloid deposit. There was no evidence of primary amyloidosis as bone marrow examination was normal. Serum and urine immunofixation electrophoresis were normal. Immunoperoxidase staining for serum amyloid associated protein for secondary amyloidosis was negative from liver biopsy. We present this rare case of primary hepatic amyloidosis and review the literature regarding varied presentations of hepatic involvement in amyloidosis.

Malaria is a parasitic and vector determined blood-conceived infectious disease transmitted through infected mosquitoes. Anti-malarial drug resistance is a major health problem, which hinders the control of malaria. A Results of a survey of drug-resistant malaria demonstrated safe proclivity to nearby all anti-malarial regimes accessible except from artemisinin and its derivatives. Artemether is a BCS class IV drug effective against acute and severe falciparum malaria;hence there is a strong need to improve its solubility. Silica is one of the most widely studied excipients. Silica can be used in solubility enhancement by preparing its solid solution/dispersion with the drug. The objective of this research was to improve dissolution rate of Artemether using non-precipitated porous silica(Aeroperl 300 Pharma) and precipitated silica like EXP. 9555, EXP. 9560, and EXP. 9565. Specific surface area calculated from BET method of porous silicas viz. APL 300(A), Exp. 9555(B), Exp. 9560(C), Exp. 9565(D) was found to be 294.13 m^2/g(A), 256.02 m^2/g(B), 213.62 m^2/g(C) and 207.22 m^2/g(D) *** drug release from the developed formulation was found to be significantly higher as compared to neat ARM. This improved solubility and release kinetics of ARM may be attributed to high surface area, improved wettability and decreased crystallinity. Solid-state characterization of the developed optimized formulation F3 was carried out with respect to FTIR chemical imaging, XRD,SEM, and DSC. All the porous silicas which we have explored in the present context showed a significant capability as a carrier for solubility enhancement of ARM.
