Problem statement: With extensive digitization of images, diagrams and paintings, traditional keyword based search has been found to be inefficient for retrieval of the required data. Content-Based Image Retrieval (CBIR) system responds to image queries as input and relies on image content, using techniques from computer vision and image processing to interpret and understand it, while using techniques from information retrieval and databases to rapidly locate and retrieve images suiting an input query. CBIR finds extensive applications in the field of medicine as it assists a doctor to make better decisions by referring the CBIR system and gain confidence. Approach: Various methods have been proposed for CBIR using image low level image features like histogram, color layout, texture and analysis of the image in the frequency domain. Similarly various classification algorithms like Naïve Bayes classifier, Support Vector Machine, Decision tree induction algorithms and Neural Network based classifiers have been studied extensively. We proposed to extract features from an image using Discrete Cosine Transform, extract relevant features using information gain and Gaussian Fuzzy Feed Forward Neural Network algorithm for classification. Results and Conclusion: We apply our proposed procedure to 180 brain MRI images of which 72 images were used for testing and the remaining for training. The classification accuracy obtained was 95.83% for a three class problem. This research focused on a narrow search, where further investigation is needed to evaluate larger classes.

Litopenaeus vannamei is a new species to India; right now culture technology is not comparable with black tiger shrimp.Bearing all those in mind the present study was carefully carried out. In the present study an attempt has been made to culture the white leg shrimp, L. vannamei in two ponds each with 0.6 ha in Kodakaramulai, Sirkali taluk, Nagai District, Tamilnadu. The salinity of the two ponds was ranging between 22-30 ppt and DO values fluctuated between 4.0 mg/l and 5.0 mg/l in the morning and between 4.5 mg/l and 6.5 mg/l in the evening. Ammonia was recorded maximum 0.3ppm and minimum was 0.1ppm. During the culture after 50 th DOC there was a poor growth observed in both ponds due to white gut and white fecal matter. Immediately feed probiotic (Bacillus sp) mix with the feed for three weeks and two meals per day. The problem was slowly rectified. The maximum Survival 85% in pond 2 and 82% survival was recorded in pond1. The present study confirm that, shrimp farming community need more awareness to use feed probiotic, proper water quality management and feed management is essential for the successful culture.

Serum amylase and lipase are commonly used tests for diagnosing pancreatitis. Serum amylase level is usually high in the early days of pancreatitis which subsequently decreases. Serum lipase is not routinely available in every hospital. We report an unusual case of pancreatitis where amylase was normal initially then it began to rise.A 71-year-old lady was admitted with an acute onset of epigastric/right upper quadrant pain without any radiation. She was also vomiting and constipated for three days. Her past medical history included open cholecystectomy, myocardial infarction, emphysema, incisional hernia repair related to cholecystectomy scar, type 2 diabetes, and hysterectomy. On examination, she was apyrexial, with normal vital signs. Clinical examination showed morbid obesity, some asymmetrical bulge in right upper quadrant above the cholecystectomy scar without cough impulse and tenderness in the epigastrium and right hypochondrium. Chest and abdominal X-rays were within the normal limits. Her initial blood tests showed an amylase of 56 U/L, obstructive-type jaundice, and the remaining blood tests were within the normal range. Arterial blood gas did not show any acidosis. Her pain deteriorated. A computed tomography scan was organized, which excluded any recurrent hernia via cholecystectomy scar. A magnetic resonance cholangiopancreatography excluded any obstruction in the common bile duct. There was a diagnostic dilemma even after two scans investigating the cause of her abdominal pain. Bloods tests were repeated the following day which showed an amylase of 500 U/L and elevated urea from dehydration. She scored two on Ranson's criteria and was treated for pancreatitis. Her condition improved with analgesia and supportive treatment.As a rule, amylase should be checked in all abdominal pain. A normal amylase does not exclude pancreatitis. Amylase is secreted by salivary gland and pancreas. The enzyme is excreted in the urine. Therefore amylase levels usually will come back to normal in three or four days after development of pancreatitis. This case is unusual because amylase was normal initially and increased after 48 hours. Sometimes it may be difficult to explain the cause of abdominal pain, particularly in an obese individual with numerous co-morbidities.
