The implementation of the Milan criteria (MC) in 1996 has dramatically improved prognosis after liver transplantation (LT) in patients with hepatocellular carcinoma (HCC). Liver transplantation has, thereby, become the standard therapy for patients with "early-stage" HCC on liver cirrhosis. The MC were consequently adopted by United Network of Organ Sharing (UNOS) and Eurotransplant for priorit...

A bacterial colony on the surface of a solid medium is regarded as a grouping of cells arranged as a result of physical restrictions imposed by the surface of the medium. It is limited in size by the physical nature of, and changes occurring at, this surface (Knaysi, 1951). In a biological sense the bacterial colony is a macromorphological collection of cells rarely found in nature (Pringsheim,...

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...
