An Unusual Melanocytic Nevus of Conjunctiva : Balloon Cell Nevus

Melanocytic nevi are one of the most common benign tumors of the conjunctiva. The balloon cell nevus is a rare and unusual variant of nevus of melanocytic origin, in which more than 50% of the tumor is composed of large polygonal cells with small nucleus and a clear to vacuolated cytoplasm. We describe a case of balloon cell nevus in a 6-year-old child who presented with pigmented lesion of the right eye since birth. The melanocytic nature of these cells was confirmed by immunohistochemical study. Excision of the tumor results in cure. This report describes a rare balloon cell nevus of conjunctiva which to the best of our knowledge is not documented in Indian literature

Primary Cutaneous Low Grade Mucinous Adenocarcinoma of Eyelid

Primary cutaneous mucinous adenocarcinoma is a rare adnexal neoplasm, eyelid being the most common site of presentation. Clinically it is mistaken for a benign / cystic lesion. Its morphologic similarity to metastatic deposits from breast, gastrointestinal tract (GIT) or any visceral sites adds to the diagnostic difficulty mandating the role of ancillary techniques in precise diagnosis and hence planning the management. We report a case of primary cutaneous mucinous adenocarcinoma of eyelid with emphasis on pathology along with a brief review of literature

Emperipolesis in a Case of Adult T Cell Lymphoblastic Lymphoma (Mediastinal type)-Detected at FNAC and Imprint Cytology

Emperipolesis is a condition in which viable hematopoetic cells are seen intact in the cytoplasm of host cell without damage. This phenomenon is seen in many physiologic and pathologic conditions, its presence in Rosai Dorfman disease (RDD) is characteristic of the disease. However emperipolesis is an uncommon finding in malignant lymphoma both Hodgkins and non-Hodgkin’s lymphoma, wherein it has been described in bone marrow aspirate and tissue culture. In contrast there are only two case reports of emperipolesis phenomenon described in non-Hodgkin’s lymphoma in tissue sections. We report a case of an adult T cell lymphoblastic lymphoma (mediastinal type) with features of emperipolesis demonstrated at fine needle aspiration cytology (FNAC) and imprint cytology of cervical lymph nodes. To our knowledge, this is the first case report of emperipolesis in a case of adult T cell lymphoblastic lymphoma (mediastinal type)-detected at FNAC and imprint cytology

Indian Finfish Exports – An Analysis of Export Performance and Revealed Comparative Advantage

The export of finfish from India has been rising over the past few years and in 2006-07 it contributed almost 44 per cent of the total marine products exported from the country in quantity terms. However in value terms its contribution is only 16 per cent, indicating low unit value realization of the products. This paper has analysed the export performance and has studied the revealed comparative advantage of finfish export from India for the period 2001 to 2005. The finfish exports from India have not revealed any comparative advantage among the total marine products export in the period of study. The paper has suggested reviewing of the policy of finfish export, with a shift in emphasis to export of only high-value finfish and value-added low-value finfish.Agricultural and Food Policy,

Finite element analysis of open die extrusion of Al-5Zn-1Mg alloy

In this work, an effort has been made to study the open die extrusion of Al-5Zn-1Mg alloy using finite element analysis. The two basic parameters of open die extrusion, i.e., die included angle and the extrusion strain are varied to find the corresponding limiting strain values. Effect of main parameters on the open die extrusion is analyzed, and the limiting range of deformation is obtained. The results obtained are verified by means of contrasting with the experimental data. Pure open die extrusion is found to be possible for extrusion strain (relative strain during extrusion) up to 0.28. However, as the extrusion strain increases from 0.09 to 0.28, upsetting dominates over pure extrusion on varying the die angle from 12° to 40°

Algal carbon sequestration in rice soil eco system

This Technical brief is a short summary of the results obtained from the field experiments conducted at Anbhil Dharmalingam Agricultural College and Research Institute, Trichy to study the algal succession in rice soil besides quantifying the biomass generation potential of different Cyanobacterial species, namely Nostoc, Anabaena, Westiellopsis and Plectonema, isolated from Cauvery basin as a part of the ClimaRice project during the summer season 2010. Higher Nostoc abundance coincided with lower of other two genera. Anabaena was the first cyanobacterial species to develop in field two weeks after transplantation of rice. Many rice-field soils not only contain a high density of cyanobacteria, but possess visually obvious growths of cyanobacteria at (or floating above) the surface, during most part of the growth stages. Cyanobacteria which multiplies easily in rice field ecosystem has great potential as biofertilizer, also it could be employed for sequestering atmospheric carbon in paddy soils

A Comparison of Deep Learning Techniques for Glaucoma Diagnosis on Retinal Fundus Images

Glaucoma is one of the serious disorders which cause permanent vision loss if it left undetected. The primary cause of the disease is elevated intraocular pressure, impacting the optic nerve head (ONH) that originates from the optic disc. The variation in optic disc to optic cup ratio helps in early detection of the disease. Manual calculation of Cup to Disc Ratio (CDR) consumes more time and the prediction is also not accurate. Utilizing deep learning for the automatic detection of glaucoma facilitates precise and early identification, significantly enhancing the accuracy of glaucoma detection. The deep learning technique initiates the process by initially pre-processing the image to achieve data augmentation, followed by the segmentation of the optic disc and optic cup from the retinal fundus image. From the segmented Optic Disc (OD)and Optic Cup (OC) feature are selected and CDR calculated. Based on the CDR value the Glaucoma classification is performed. Various deep learning techniques like CNN, transfer learning, algorithm was proposed in early detection of glaucoma. From the comparative analysis glaucoma diagnosis, the proposed deep learning artifact Convolutional Neural Network outperform in early diagnosis of glaucoma providing accuracy of 99.3 8%

Analysis of coconut cultivars and hybrids using isozyme polymorphism

The coconut (Cocos nucifera L.) is one of the major oilseeds of India. In the present study, an attempt has been made to analyse coconut diversity using isozyme banding data. Cluster analysis was performed using the banding patterns obtained from polyacrylamide gel electrophoresis for 11 isozyme systems in 40 different coconut cultivars and six hybrids and their parents. The cultivars grouped mainly into six clusters. In case of hybrids and their parents, the hybrids clustered intermediate between parents
