An early detection and segmentation of Brain Tumor using Deep Neural Network.

Background: Magnetic resonance image (MRI) brain tumor segmentation is crucial and important in the medical field, which can help in diagnosis and prognosis, overall growth predictions, Tumor density measures, and care plans needed for patients. The difficulty in segmenting brain Tumors is primarily because of the wide range of structures, shapes, frequency, position, and visual appeal of Tumors, like intensity, contrast, and visual variation. With recent advancements in Deep Neural Networks (DNN) for image classification tasks, intelligent medical image segmentation is an exciting direction for Brain Tumor research.

Improvement in biochemical characteristics of cross-linked enzyme aggregates (CLEAs) with magnetic nanoparticles as support matrix.

Recent developments in novel carriers for enzyme immobilization have led to improvement in the stability and cost-effectiveness of the biocatalysts for their enhanced suitability in the industrial applications. Cross-linked enzyme aggregates (CLEAs), a recent technique developed in the carrier-free type of enzyme immobilization is a simple and straightforward method. Moreover, the magnetic property and the higher surface-to-volume ratio of the maghemite nanoparticles have also been utilized in the present immobilization technique as magnetic nanoparticle-supported CLEAs (Mgnp-CLEAs).

Enhanced stability of immobilized keratinolytic protease on electrospun nanofibers.

Feathers from poultry industries are considered a major pollutant and its degradation is a challenging problem due to its recalcitrant nature. The high cost of energy and loss of essential amino acids by conventional methods have paved a way for an environmentally benign approach using microbial keratinolytic proteases. The widespread application of keratinolytic proteases is limited due to autolysis and denaturation of the enzyme upon storage.

Cross-linked esterase aggregates (CLEAs) using nanoparticles as immobilization matrix.

The present study focusses on the enhancement of the catalytic activity and stability of an acetylesterase enzyme isolated from Staphylococcus spp. as Cross-Linked Enzyme Aggregates (CLEAs). The various parameters governing the activity of CLEAs were optimized.

Detection and neutralization of cobra venom using rabbit antiserum in experimental envenomated mice.

A sandwich enzyme-linked immunosorbent assay (ELISA) was developed to detect the venom of Indian cobra (Naja naja naja) in various tissues (brain, heart, lungs, liver, spleen, blood, kidneys, and tissue at the site of injection) of mice after cobra venom injected at different time intervals (0, 2, 4, 6, 8, and 12 h intervals up to 24 h). Whole venom antiserum or individual venom protein antiserum (14, 29, 65, 72, and 99 kDa) could recognize N. n.
