Wheat yields in many parts of India are stagnant. The main reason forthis is conventional blanket fertilizer recommendation, lower fertilizer useefficiency, and imbalanced use of fertilizers. Estimation of fertilizerrequirements based on quantitative approaches can assist in improving wheatyields and increasing nutrient use efficiency. We used the QUEFTS(More)
OBJECTIVES Decreased magnetization transfer ratio (MTR) in the brain characterizes cerebral edema (CE) in patients with liver cirrhosis, but the role of treatment on its reversibility has not been studied in patients who have minimal hepatic encephalopathy (MHE). This study was carried to evaluate the reversibility of CE with lactulose and rifaximin(More)
Nitrogen is the most widely used fertilizer nutrient, and it is a universally deficient nutrient too, which often severely restricts the growth and yield of crops. To improve N fertilizer management, soil-plant system models can be applied to simulate adequate N supply for both, optimal crop growth and minimal N losses. The likely impact of climate change(More)
We present a rare case of a solitary cysticercal cyst that involved the anterior abdominal wall musculature and was diagnosed with sonography. Sonograms revealed a small, well-defined, elliptical cystic lesion with an eccentric hyperechoic area within it. An eccentric, echogenic, pedunculated structure was seen within the cystic area of the lesion. No(More)
There are limited data on nonalcoholic fatty liver disease (NAFLD) from India. The clinicopathological profile of Indian patients with NAFLD may be different from that of Western patients. One hundred NAFLD patients with increased liver enzymes were prospectively evaluated for clinical presentation, associated diseases, overweight/obesity, central obesity(More)
A system to characterize normal liver, cirrhotic liver and hepatocellular carcinoma (HCC) evolved on cirrhotic liver is proposed in this paper. The study is performed with 56 real ultrasound images (15 normal, 16 cirrhotic and 25 HCC liver images) taken from 56 subjects. A total of 180 nonoverlapping regions of interest (ROIs), i.e. 60 from each image(More)
OBJECTIVE Our objective was to assess the efficacy of single-arterial-phase, 16-slice multidetector computed tomographic (16-MDCT) angiography in the evaluation of both the renal arterial and venous systems in prospective renal donors with surgical (laparoscopic) correlation. METHODS Fifty-one consecutive renal donors (age range, 20-62 years; 12 men and(More)
CONTEXT Emphysematous pancreatitis is a rare, potentially fatal variant of severe acute pancreatitis with gas in the pancreatic bed. There are isolated case reports describing this condition. OBJECTIVE This report summarizes our experience with the management of this condition in order to compare its clinical characteristics, microbiological and(More)
Portal cavernoma cholangiopathy (PCC) is defined as abnormalities in the extrahepatic biliary system including the cystic duct and gallbladder with or without abnormalities in the 1st and 2nd generation biliary ducts in a patient with portal cavernoma. Presence of a portal cavernoma, typical cholangiographic changes on endoscopic or magnetic resonance(More)
Portal cavernoma cholangiopathy (PCC) refers to the biliary changes which occur in the setting of extrahepatic portal vein obstruction and secondary portal cavernoma formation. The main radiological findings include the vascular changes in the form of portosystemic collaterals and biliary changes in the form of extrinsic impressions and strictures. Till(More)
