An apoplastic pathway, the so-called bypass flow, is important for Na+ uptake in rice (Oryza sativa L.) under saline conditions; however, the precise site of entry is not yet known. We report the results of our test of the hypothesis that bypass flow of Na+ in rice occurs at the site where lateral roots emerge from the main roots. We investigated Na+ uptake(More)
Specific functional properties of many proteins directing developmental responses via transcriptional regulation are orchestrated by their characteristic helix-loop-helix (HLH) structural motif. The entire HLH motif in all these proteins assumes a common conformation irrespective of their individual biological effects. The motif controls the affinity of HLH(More)
Macrognathus aculeatus (Bl.) and Mastacembelus pancalus (Lac.) (Family: Mastacembelidae) are considered to be the most delicious fish in Andhra Pradesh due to the tenderness of their muscles. The metacercariae of Clinostomum mastacembeli Jaiswal, 1957 are found infesting the oesophagus of these fishes heavily. During present studies, histopathological(More)
A new species of the cestode genus Tylocephalum obtained from the host Dasyatis uarnak is described. A detailed examination of specimens have allowed us to erect a new species Tylocephalum to accommodate the worm. It shows remarkable differences from other known species of Tylocephalum in large size of the worm, absence of neck, variation in number of(More)
A young girl presented with Budd-Chiari syndrome (BCS) with narrowing of the retrohepatic segment of inferior vena cava (VC). Dorsal cavoatrial bypass (DCAB) was unsuccessful due to thrombotic occlusion of the graft. A limited autopsy revealed occlusion of the retrohepatic segment of IVC and the terminal parts of the three major hepatic veins. Caval(More)
A new species of a cestode, belonging to genus Phyllobothrium, obtained from spiral valve of the intestine of the elasmobranch Rhinoptera javanica is described. It shows remarkable differences from other known species of Phyllobothrium in having big scolex, bifurced and sessile nature of bothridia, testes number and nature of proglottids. The new species is(More)
Gene expression profiling has been successfully use to identity potential cancer diagnosis and therapeutic target in the past few years. Since there are often large number of potential genes, an important issue is to find a small subset of genes that are differentially expressed between different clinical outcomes (or) related subset to cancer patients(More)
Fishes serve as intermediate hosts to a number of avian digenetic trematodes. A survey on 10 different species of freshwater fishes belonging to 8 families from River Godavari from August 2005 to September 2007 revealed a total of 10 metacercariae of digenetic trematodes from five families i.e., Clinostomidae Lühe, 1901; Diplostomidae Poirier, 1886;(More)
A total of 9 metazoan parasitic species were identified from Mystus vittatus (Bloch) in river Godavari during 2005-2007 including 2 monogeneans, 2 digeneans, 3 acanthocephalans and 2 copepods. Two species of monogeneans (Bifurcohaptor indicus and Thaparocleidus tengra), digeneans (Haplorchoides macrones and metacercariae of Isoparorchis hypselobagri), an(More)
The freshwater eel, Mastacembelus armatus Lacépède, 1800 is often found infected with adults and larval plerocercoids of the cestode, Circumonchobothrium shindei. The population dynamics of C. shindei was studied in the freshwater eel, M. armatus during September 2005 to August 2007 from Godavari River, Rajahmundry. A total of 494 eels were examined; 184(More)
