Item Congenitally unguarded tricuspid valve orifice with a giant right atrium and a massive clot in an asymptomatic adult.(2001-07-05) Mohan, J C; Sengupta, P P; Arora, RCongenitally unguarded tricuspid valve orifice, a variant of tricuspid valve dysplasia, is a rare malformation with protean manifestations. This report describes an asymptomatic adult who, on echocardiographic examination ordered in view of an abnormal 12-lead surface electrocardiogram and plain chest X-ray, was found to have an unguarded tricuspid valve orifice with a giant right atrium (12 x 10 cm), intense spontaneous echo contrast and a large right atrial clot.Item Development of an enzyme immunoassay using recombinant invariant surface glycoprotein (rISG) 75 for serodiagnosis of bovine trypanosomosis.(2015-01) Rudramurthy, G R; Sengupta, P P; Metilda, B; Balamurugan, V; Prabhudas, K; Rahman, HTrypanosomosis or surra is caused by the haemoflagellate parasite, Trypanosoma evansi and is an important disease of animals, including domestic and wild herbivores and carnivores, in tropical countries. The invariant surface glycoproteins (ISGs) are blood stream stage specific and are uniformly distributed over the entire surface of the trypanosomes. In the present study, the extracellular domain (ED) region of ISG-75 from T. evansi, consisting of 1320 nt, encoding a polypeptide of 440 amino acids, has been heterologously expressed in Escherichia coli. Further, the immunoreactivity of recombinant ISG-75 (rISG-75) was characterized in immunoblot and ELISA using T. evansi hyper immune sera raised in experimental animals. The protein was found immunoreactive when compared with a panel of antigens (VSG RoTat 1.2 and whole cell lysate) using bovine serum samples from field. The diagnostic potential of rISG-75 was evaluated in ELISA with large number of bovine field serum samples. The optimum sensitivity and specificity were 98.47 and 99.1, respectively. The present finding showed that the expressed protein has potential use in the serodiagnosis of trypanosomosis.Item Ebstein's anomaly with coarctation of the aorta--an unusual association.(1996-05-01) Salkar, H R; Salkar, R G; Sengupta, P PItem Noncompaction of left ventricular myocardium in the presence of calcific aortic stenosis in an adult.(2001-11-13) Sengupta, P P; Mohan, J C; Arora, RWe describe an adult patient with a hitherto unreported association of severe aortic stenosis with extensive noncompaction of the left ventricular myocardium without any hypertrophy; however, there was severe left ventricular systolic dysfunction in the presence of a normal-sized left ventricular cavity on two-dimensional echocardiography. This condition was differentiated from persistence of embryonic intramyocardial sinusoids by selective coronary angiography.
