In recent year there has been rapid increase in the standardization of selected medicinal plant of potential therapeutic significance. Despite the morden techniques, identification of plant drug by Pharmacognostic study is more reliable. The rhizomes of Curcuma longa reported to have good medicinal values in traditional system of medicines. The present study deals with pharmacognostic parameter...

The filamentous fungus Aspergillus niger is an important production host in biotechnology. Shear force regimes are one of the key factors that affect macromorphology and product yield. While morphology changes under intensive agitation have been widely investigated, studies at a low shear regime independently from oxygen limitation has remained challenge. Therefore, this study, 2-dimensional ro...

A chemotaxonomic survey of 380 species of Aloe indicated the presence of the anthrone isomers aloin A and B together with the aloinoside isomers and microdontin A and B in 36 (10%) species of Aloe. This group, referred to as the microdontin chemotype, is thus characterised by a combination of exudate compounds and not merely a single phytochemical marker, implying taxonomic significance of leaf...

Amyloid curli fibers and cellulose are extracellular matrix components produced in the stationary phase top layer of E. coli macrocolonies, which confer physical protection, strong cohesion, elasticity, and wrinkled morphology to these biofilms. Curli and cellulose synthesis is controlled by a three-level transcription factor (TF) cascade with the RpoS sigma subunit of RNA polymerase at the top...

The extraction of teeth results in rapid bone resorption both vertically and horizontally in the first month. The loss of alveolar ridge reduces the chance of implant rehabilitation. Atraumatic extraction, implant placement in extraction socket, and an immediate prosthesis have been proposed as alternative therapies to maintain the volume and contours tissue and reduce time and cost of treatmen...
