The records of these tumors were retrieved and analyzed, focussing on the prevalence according to age, sex and types of tumors. Results: Maximum number of cases (50.98%; 26/51) were seen in 10-14 years age group, followed by 29.41% (15/51) cases in 5-9 years age group and 19.61% (10/51) in 0-4 years. Males were affected in 68.63% (35/51) cases, while females were affected in 31.37% (16/51) cases. Male to female ratio was 2.2:1. Leukemias were found to be the most common pediatric cancers (29.4%; 15/51 cases), followed by lymphomas (17.65%; 09/51 cases), malignant bone tumors (11.8%; 06/51 cases), renal malignancies (9.8%; 05/51 cases), brain tumors, soft tissue sarcomas and germ cell tumors (7.8%; 04/51 cases each). In <5 years and 5-9 years age group, Acute Lymphoblastic Leukemia (ALL) was the predominant malignancy (30% and 26.67% respectively). In 10-14 years of age, both ALL and Osteosarcoma accounted for the majority cases (15.38% each). Conclusion: This institution based study provides an insight into the pattern of distribution of childhood cancers in Western Uttar Pradesh region, which is important in the planning and evaluation of health strategies. In India, where there is scarcity of data because of lack of a dedicated pediatric cancer registry, such studies play a major role in effective disease management for this small but important group of patients.

A Framework for Classification of Prokaryotic Protein Kinases

Nidhi Tyagi, Krishanpal Anamika, Narayanaswamy Srinivasan, Alan Ruttenberg
2010 PLoS ONE  
Overwhelming majority of the Serine/Threonine protein kinases identified by gleaning archaeal and eubacterial genomes could not be classified into any of the well known Hanks and Hunter subfamilies of protein kinases. This is owing to the development of Hanks and Hunter classification scheme based on eukaryotic protein kinases which are highly divergent from their prokaryotic homologues. A large dataset of prokaryotic Serine/Threonine protein kinases recognized from genomes of prokaryotes have
more » ... een used to develop a classification framework for prokaryotic Ser/Thr protein kinases. Methodology/Principal Findings: We have used traditional sequence alignment and phylogenetic approaches and clustered the prokaryotic kinases which represent 72 subfamilies with at least 4 members in each. Such a clustering enables classification of prokaryotic Ser/Thr kinases and it can be used as a framework to classify newly identified prokaryotic Ser/Thr kinases. After series of searches in a comprehensive sequence database we recognized that 38 subfamilies of prokaryotic protein kinases are associated to a specific taxonomic level. For example 4, 6 and 3 subfamilies have been identified that are currently specific to phylum proteobacteria, cyanobacteria and actinobacteria respectively. Similarly subfamilies which are specific to an order, sub-order, class, family and genus have also been identified. In addition to these, we also identify organism-diverse subfamilies. Members of these clusters are from organisms of different taxonomic levels, such as archaea, bacteria, eukaryotes and viruses. Conclusion/Significance: Interestingly, occurrence of several taxonomic level specific subfamilies of prokaryotic kinases contrasts with classification of eukaryotic protein kinases in which most of the popular subfamilies of eukaryotic protein kinases occur diversely in several eukaryotes. Many prokaryotic Ser/Thr kinases exhibit a wide variety of modular organization which indicates a degree of complexity and protein-protein interactions in the signaling pathways in these microbes.

A Novel Architecture of Ontology-based Semantic Web Crawler

Ram KumarRana, Nidhi Tyagi
2012 International Journal of Computer Applications  
Finding meaningful information among the billions of information resources on the Web is a difficult task due to growing popularity of the Internet. The future of World Wide Web (WWW) is the Semantic Web, where ontologies are used to assign (agreed) meaning to the content of the Web. On the Semantic Web, data will inevitably be linked to many different ontologies, and information processing across ontologies is not possible without knowing the semantic mappings between them. As the resources on

For this, architecture has been proposed for ontology based semantic web crawler. This architecture can exploit the semantic metadata to efficiently discover and extract information from the Semantic Web. In this paper Semantic matching between content of downloaded web page and ontology is used to guide the crawler towards relevant information. General Terms: Information Retrieval, Search Engine, Web Crawling and Semantic Matching.

All the cases were subjected to detailed history, physical examination and radiological investigations. FNAC smears were stained with Giemsa and Papanicolaou stain. H and E staining was done for histopathology.Results: Mean age affected was 26 years. Male-female ratio was 2.8:1. Out of total 64 cases of bone tumors and tumor like lesions, maximum was chondrogenic tumors (17; 26.56%), followed by osteogenic tumors (15; 23.44%). Osteochondroma (08; 47.06%), Osteosarcoma (07; 46.66%) and Aneurysmal bone cyst (04; 50.0%) were the most common chondrogenic tumor, osteogenic tumor and tumor like lesion respectively. The most common bone affected was tibia (16; 25.0%), followed by femur (15; 23.4%). Sensitivity and specificity of FNAC as a diagnostic modality were 90.0% and 91.67% respectively.Conclusions: A good correlation is observed between cytological and histological diagnoses which implies that FNAC can be used as a preliminary diagnostic approach to bone tumors, although histopathology remains the gold standard.

This number is estimated to increase to 430 million in the absence of better control or cure. Different types of diabetes mellitus, type 1, type 2, gestational diabetes and other types of diabetes mellitus are compared in terms of diagnostic criteria, etiology and genetics. As the disease progresses tissue or vascular damage ensures leading to severe diabetic complications such as retinopathy, neuropathy, nephropathy, cardiovascular complications and ulceration. Currently available pharmacotherapy for the treatment of diabetes mellitus includes insulin and hypoglycemic agents. These drugs act by increasing the secretion of insulin form pancreas or reducing plasma glucose concentrations by increasing glucose uptake and decreasing gluconeogenesis. Comobrid mental diseases can further negatively influence the course of diabetes. They are specially depression, anxiety disorders, eating disorders and cognitive disorders including dementia. Various herbal drugs have been also proved effective due to their beneficial contents in treatment of diabetes. This article focuses on the causes, types, diagnosis and treatment of diabetes.
