Criteria for the classification of bacterial viruses were proposed by Burnet (1933), including particle size, serological relationship, and certain physiological characteristics. These criteria were applied to the definition of 12 serological groups of coli-dysentery phages. This taxonomic scheme was an important advance since it embodied the concept of phylogenetic relationships among the bact...

Some sciences are exciting because of their generality and some because of their predictive power. Immunology is particularly exciting, however, because it provokes unusual ideas, some of which are not easily come upon through other fields of study. Indeed, many immunologists believe that for this reason, immunology will have a great impact on other branches of biology and medicine. On an occas...

Guided by a hemostasis bioassay, seven terpene glycosides were isolated from the roots of Sanguisorba officinalis L. by silica gel column chromatography and preparative HPLC. On the grounds of chemical and spectroscopic methods, their structures were identified as citronellol-1-O-α-L-arabinofuranosyl-(1→6)-β-D-glucopyranoside (1), geraniol-1-O-α-L-arabinofuranosyl-(1→6)-β-D-glucopyranoside (2),...

Sanguisorba officinalis is a natural plant that has been traditionally used for the treatment of inflammatory and metabolic diseases. Several studies have reported that its extracts exhibit anticancer, antioxidative and anti-lipid peroxidation activities. However, the effects of this plant on human prostate cancer cells have not yet been investiga...

Nature conservation requires classification of vegetation types for site assessment and assignment. Species-rich floodplain meadows are a declining habitat in Britain Europe yet their has been based on just few samples fails to describe community response environmental change adequately. European classification, opposite, from the wide geographical range with no data/analysis supporting choices...

Sir Macfarlane Burnet [1], who is far famed for his pioneer work on cancer surveillance, recommended clearly in his Brailsford Robertson Memorial Lecture that scientists should acquaint themselves with historical antecedents. Therefore, this paper documents such antecedents in respect of the drug treatment modalities used by cancer quacks. Quacks were presented in the 1725 History of Physic by ...
