1 The structure and function of the different antibody isotypes are described in Table 20-1. The specificity of an antibody is determined by the amino acid sequence of its antigen-binding site. The variability in sequence that accounts for the enormous diversity of the antibody repertoire is ...
The fetuses of rats treated by AlCl3, show no change in the histological structure of the spleen. The AlCl3 action is more marked than mothers in their fetuses. This certifies that the placenta forms a more or less selective barrier to some constituents, and that spleen in fetuses temporarily...
In the placental villi, nearly the entire maternofetal and fetomaternal exchange takes place. There is only a limited contribution to this exchange by the extraplacental membranes. In addition, most metabolic and endocrine activities of the placenta have been localized in the villi (for review, s...
[61]. Recently, by comparing the nucleotide compositions of transcriptomes across 1,000 plants from different habitats, G-rich transcriptomes that tended to form RNA G4s were identified in plants growing in cold climates. Moreover, RNA G4s were found to be responsive to cold treatment in...

A cavity begins to form, and fluid moves into this space by the cells of the outer layer in a process called cavitation that is meant to keep other material out. The space that forms a safe layer of fluid between the outer and inner layers is called the blastocoel. All cell division ...
(bp) with only noncoding repeats, while some could contain DNA fragments up to several megabase pairs and even acquire all the genetic elements required for its replication and propagation of the genetic material.4,5The existence of eccDNA is such a common phenomenon that it has been found in...
Several earlier studies have demonstrated thatGPHRsform oligomers under physiological conditions. LHR forms oligomersin vitroas well asin vivo(Rivero-Muller et al., 2010; Urizar et al., 2005). The oligomer behaves as a single monomer and activation of a single protomer is enough forsignal transd...
(NHT). The α-helical tail forms a coiled-coil through hydrophobic interactions that direct the self-assembly of two myosin heavy chains and the bound light chains into an elongated hexameric complex of ~ 525 kDa that is referred to as the monomer. The monomer is the basic building block...
