The formation of endospores is one of the most effective survival strategies that have been discovered by microorganisms over eons. Vegetative cells start dividing asymmetrically after receiving a trigger pulse whereby the smaller part of the cell develops into forespore. The final endospore body is build of a special protective coating (the cortex) and contains a high concentration of calcium-...

Pullulanase. a debranching enzyme that specifically cleaves a 1.6 linkages in amylopectin and pullulan, differs from a-amylase which hydrolyses the a 1,4 linkages of starch, amylose and amylopectin [ I ] . Pullulanases are inactive against linear a 1,4 linkages and a-amylases do not hydrolyse pullulan. Some novel amylolytic enzymes capable of hydrolysing both starch and pullulan have been disco...

teria and their relatives,” are a major class of bacteria (Gupta, 2000; Holt et al., 1994; Stackebrandt et al., 1988; Zinder, 1998). This group of predominantly Gram-negative bacteria contains more than 200 genera with a great diversity of phenotypic and physiological attributes. Proteobacteria have been classified based on homology of 16S ribosomal RNA or by hybridization of ribosomal RNA or D...

compounds. They exhibit antianaphylactic, oral hypotensive and antiulcer properties. 2-Benzoxepine moiety is present in many useful neuroleptic (pinoxepin), antidepressant (spiroxepin) and anti-inflammatory agents (isoxepac and oxepinac). The synthesis of 2-benzoxepines having different functionalities is thus necessary. As a part of our program related to the discovery of novel bioactive compo...

Chiral 3,3a,5,9b-tetrahydro-2H-furo[3,2-c][2]benzopyrans (TFBs) were synthesized and some of them were found to be herbicidally active against annual paddy weeds through intensive structure–activity relationship studies. These compounds were synthesized from D-glucose, which was used as a natural chiral source. This was the result of a series of studies based on the findings that certain benzyl...

Figure 6. T2*W images of a breast tumour. (a-c) Sagittal T2W (a), dynamic contrast-enhanced (DCE) subtracted image at time point 2.44 minutes (b), and T2*W image (c) in a patient with a palpable breast lump in the upper outer quadrant. The tumour seen in (a) and highlighted in (b) shows heterogeneity of T2* with faster signal decay in the inferior part of the tumour, indicating a greater deoxyh...
