The question of the molecular weight of the specific polysaccharides is one of great importance for an understanding of the mechanism of immune reactions. It has been found that the precipitin reaction, for example, may be accounted for as a chemical combination of antigen (or haptene) with antibody globulin in proportions depending on the relative amounts of antigen (haptene) and antibody pres...

We present an experimental investigation of the segmental relaxation behavior of polystyrene (PS) chains that are confined in a micellar core tethered by a poly(acrylic acid) (PAA) block corona on the dry film surface, along with various core density and molecular weight of PS block from below to well above the entanglement molecular weight. The results show that the onset temperature of PS cha...

AIM The purpose of this study was to assess the relation of perinatal risk factors with later development of specific language impairment (SLI). METHOD In a case-control study, 179 children attending special needs schools for SLI were matched with non-affected children attending mainstream schools. Both groups consisted of 134 males and 45 females (age range 4-13 y; mean age 9 y, SD 2 y 4 mo)...

BACKGROUND In a number of diseases, certain genes are reported to be strongly methylated and thus can serve as diagnostic markers in many cases. Scientific literature in digital form is an important source of information about methylated genes implicated in particular diseases. The large volume of the electronic text makes it difficult and impractical to search for this information manually. ...
