Background: Anomalous junction of the pancreaticobiliary duct (AJPB) is a rare finding in endoscopic retrograde cholangiopancreatography (ERCP). We present our data on the incidence of AJPB and associated diseases. Methods: A retrospective analysis of 2885 ERCPs performed over 15 years was done to study the incidence of AJPB and the diseases associated with(More)
Chemical data assimilation attempts to optimally use noisy observations along with imperfect model predictions to produce a better estimate of the chemical state of the atmosphere. It is widely accepted that a key ingredient for successful data assimilation is a realistic estimation of the background error distribution. Particularly important is the(More)
Water stress is one of the most severe constraints to crop productivity. Plants display a variety of physiological and biochemical responses both at the cellular and whole organism level upon sensing water stress. Leaf rolling, stomatal closure, deeper root penetration, higher relative water content (RWC) and better osmotic adjustment are some of the(More)
Inflammatory bowel disease (IBD) consists of Ulcerative colitis (UC) and Crohn’s disease (CD). These two conditions share many common features—diarrhea, bloody stools, weight loss, abdominal pain, fever and fatigue. Small intestinal bacterial overgrowth (SIBO) is frequent in patients with CD but it has not been studied in UC Indian patients. The study was(More)
We combine CO column measurements from the MOPITT, AIRS, SCIAMACHY, and TES satellite instruments in a full-year (May 2004–April 2005) global inversion of CO sources at 4×5 spatial resolution and monthly temporal resolution. The inversion uses the GEOS-Chem chemical transport model (CTM) and its adjoint applied to MOPITT, AIRS, and SCIAMACHY. Observations(More)
Visual steganography is the most widely practiced form of steganography. It started with concealing messages within the lowest bits of noisy images or sound files. We shall perform steganography on video files and hide the message in an encrypted format, thus achieving a multiple cryptographic system. The most commonly used technique is Least Significant(More)
Endoscopic sclerotherapy has emerged as aneffective and safe mode of treatment for long-termmanagement of esophageal varices due to cirrhosis ofliver and extrahepatic portal venous obstruction. There are few studies that have evaluated the role ofsclerotherapy in the management of esophageal varices inpatients with noncirrhotic portal fibrosis (NCPF).(More)
Our objective was to evaluate the incidence of colorectal tuberculosis in our series and to study its radiological spectrum. A total of 684 cases of proven gastrointestinal tuberculosis with positive barium contrast findings seen over a period of more than one decade were evaluated. The study did not include cases where colon was involved in direct(More)
Background: Primary small bowel tumors are rare and their preoperative diagnosis is unsatisfactory. The cornerstone of diagnosis remains contrast radiography. The present study was done to evaluate the radiologic findings of primary small bowel tumors as shown on enteroclysis and to correlate these observations with surgical and histopathologic findings.(More)
The relationship between methanogenic flora and hydrogen (H2) production is considered to be a possible confounding factor in the interpretation of hydrogen breath tests (H2BT). Therefore, the present study was conducted prospectively and included 154 IBS patients (fulfilling Rome II criteria) and 286 age-and-sex-matched apparently healthy controls. Each(More)
