Toxicity effects of hexavalent chromium on hematological, biochemical and digestive enzyme profiles of Labeo rohita (Hamilton, 1822).

The study provides a descriptive understanding of the toxic effect of heavy metal chromium on the hematological, biochemical, and digestive enzyme profiles in the fingerlings of Labeo rohita. The 96-h LC of hexavalent chromium was found to be 15.76 mg/L.

Phytoplankton diversity in wastewater impacted Indian Ramsar site: a study from East Kolkata Wetland.

A seasonal study was undertaken to understand the influence of wastewater on phytoplankton distribution in a water body of East Kolkata Wetland (EKW), a designated Ramsar site in Kolkata, West Bengal, India. A total of 19 different genera of phytoplankton belonging to 5 phyla were recorded. Among all the groups, Chlorophyceae was found to be dominated by 8 genera followed by Bacillariophycaeae (4 genera), Cyanophyceae (4 genera), Euglenophyceae (2 genera), and Zygnematophyceae (1 genus).

GC-EnC: A Copula based ensemble of CNNs for malignancy identification in breast histopathology and cytology images.

In the present work, we have explored the potential of Copula-based ensemble of CNNs(Convolutional Neural Networks) over individual classifiers for malignancy identification in histopathology and cytology images. The Copula-based model that integrates three best performing CNN architectures, namely, DenseNet-161/201, ResNet-101/34, InceptionNet-V3 is proposed. Also, the limitation of small dataset is circumvented using a Fuzzy template based data augmentation technique that intelligently selects multiple region of interests (ROIs) from an image.

Ki67, p27 and p53 Expression in Squamous Epithelial Lesions of Larynx.

Precise assessment of the biological behavior and progression of squamous epithelial lesions of the larynx with a view to predict the prognosis and therapeutic challenges remains an elusive goal. The knowledge and data regarding the expression of proliferative markers indicating the biological activity in different histological grades of squamous epithelial lesions are lacking till date. To evaluate the relationship between Ki67, p27 and p53 expression as well as topographic distribution of Ki67 with the histological subtypes or grades of laryngeal squamous intraepithelial and invasive lesions.

Toxicity of neem pesticides on a fresh water loach, Lepidocephalichthys guntea (Hamilton Buchanan) of Darjeeling district in West Bengal.

Static renewal bioassay tests were conducted to evaluate the acute toxicity of two neem based biopesticides, applied widely on tea plantation namely, Nimbecidine and Neem Gold either separately as well as, in combination to the fingerlings (mean body length- 4.46 +/- 0.15 cm; mean body weight- 0.
