Spatial confinement of excitons in the nano-crystalline region of semiconducting nanostructures differ significantly from the optoelectronic properties exhibited by the bulk material. We report spike-like absorption observed in the UV spectrum of a phenylalanine hexamer peptide [(Ff)-OH] nano-assembly, which may be attributed to the spatial confinement of electrons to the dimension of quantum dots. Interdependency of the UV and PLE spectrum of the peptide confirms the existence of quantum confinement in (Ff)-OH nano-assemblies.

In vitro fertilized (IVF) embryos were derived from slaughterhouse derived COCs and cultured in different doses of LC i.e.

Methods: Randomised, double-masked, vehicle-controlled, parallel group study conducted at 32 centres across the world.
Purpose: To characterize reticular drusen (RDR) in patients with geographic atrophy (GA) secondary to age-related macular degeneration (AMD) in a prospective, multicenter, natural history study.
Methods: Confocal scanning laser ophthalmoscopy (cSLO) three-field fundus autofluorescence (FAF; exc., 488; em.
Purpose: Altered glycosylation has been associated with oncogenic potential. Relationships of blood types (where expression is due to glycosylation pattern) and HER2/neu (where expression arises due to altered glycosylation) and breast cancer-associated markers like estrogen receptor/progesterone receptor (ER/PR) were examined and related to outcomes in patients with breast cancer.
Methods: A population-based retrospective study of 426 surgical breast cancer patients examined relationships between (1) patient characteristics, (2) breast tumor characteristics, and (3) outcomes of women diagnosed at the same medical center over a 10-year period relative to specific molecules defined by glycosylation patterns (eg.
