Electron transfer between electronically excited states and electron donors or acceptors in the ground state has been established as an important mechanism for the quenching of excited states. The paper of Rehm and Weller [1], demonstrating for several aromatic excited singlets and numerous aromatic quenchers in acetonitrlle a clear-cut correlation between the quenching rate constant kq and the...

In this issue of Blood,Weller et al studied patients with rare immunodeficiencies to demonstrate a role for Toll-like receptors (TLRs) in homeostasis of human CD27+IgM+IgD+B cells.

Phenothiazinyl and carbazolyl-donor moieties can be covalently coupled to an anthraquinone acceptor unit through an Ugi four-component reaction in a rapid, highly convergent fashion and with moderate to good yields. These novel donor-acceptor dyads are electronically decoupled in the electronic ground state according to UV-vis spectroscopy and cyclic voltammetry. However, in the excited state t...

This paper critically examines Weller and Weller's preferred last month only method for measuring synchrony. Within-woman and between-women menstrual-cycle variability are distinguished. If there is within-woman cycle variability, synchrony requires a process of entrainment. Between-women cycle variability precludes synchrony between rhythms that are not integer multiples of each other. The ass...

Since M. K. McClintock (1971) published the 1st study on menstrual synchrony among women, a number of other studies have also reported synchrony using a variety of methods. The most recent reports of synchrony come from A. Weller, L. Weller, and colleagues, and their findings of synchrony have been getting stronger (by their own account). In this article, the author analyzes their new methodolo...
