The size and physical structure of the infectious virus particle, orvirion, can be considered together because in many ways they are related. Viruses can be divided into four main categories from their appearance in the electron microscope. These include the spherical viruses, rod-shaped viruses, ...

Influenza A virus was chosen as the pathogen of interest as (i) it is an important, globally-circulating human pathogen, (ii) influenza is well characterized antigenically, (iii) a precise and repeatable serological assay was available, and (iv) the human population receives almost no influenza...
Like any other company, we too go through its own cycle of growth, expansion, streamlining and optimization. Its business decisions and market developments therefore affect its structure.

Sex differences in brain aging: a quantitative magnetic resonance imaging study (published erratum appears in Arch Neurol 1998 May;55(5):627) BACKGROUND: Little is known about the effect of sex on age-related changes in brain structure. METHODS: Quantitative magnetic resonance imaging of the ...
3.Structure of viruses Most viruses are too small to be seen under light microscope. All viruses consists of an RNA or DNA core genome surrounded by a protein coat capsid. The combined viral genome and capsid is called the nucleocapsid. The nucleic acid of a virus is surrounded by a ...
