The guinea-pig first achieved fame as an experimental animal in the eighteenth century, when Lavoisier used it for his fundamental experiments on respiration (Lavoisier & La Place, 1784; Seguin & Lavoisier, 1793). It did not, however, begin to make nutritional history till the twentieth century, when Holst & Frolich (1go7), in trying to give it beriberi, found that it developed scurvy instead; ...

INTRODUCTION Fracture of the atlas was first described by Jefferson (1920). He theorised a bursting mechanism of fracture as the occipital condyles were driven into the atlas. Experimental studies by Hays and Alker (1988) and Panjabi et al (1991) were also conducted to explain the injury mechanisms. Injury mechanisms and fracture patterns are important in the clinical evaluation of spinal injur...

Not the Opium of the People: Income and Secularization in a Panel of Prussian Counties The interplay between religion and the economy has occupied social scientists for long. We construct a unique panel of income and Protestant church attendance for six waves of up to 175 Prussian counties spanning 1886-1911. The data reveal a marked decline in church attendance coinciding with increasing incom...

Sephacryl S-300 has been compared with Sephadex G-200 in the fractionation of sera for the detection of rubella-specific IgM. No difference in sensitivity was found with sera that had low titres of rubella-specific IgM. Sephadex G-200 was apparently more sensitive with some sera which had high titres of rubella-specific IgM due to the contribution of rubella-specific IgA. Sephacryl S-300 offers...

Present concepts of the maturation of a B-lymphocytic clone involve progressive changes in cellular morphology and mode of immunoglobulin (Ig) production. The ancestral small lymphocyte synthesizes Ig for insertion into its plasma membrane, while those of its descendants destined to produce humoral antibody show first a superimposed synthesis of Ig for export and finally a heavy export with lit...
