The growing pressure on GPs to use chaperones when conducting intimate examinations (vaginal, rectal, breast, testicular) reveals an alarming deterioration in doctor–patient relationships. The peculiar intimacy of the relationship between doctor and patient renders the patient vulnerable to the doctor's abuse of power.

A primitive economic model with classical population theory is constructed in order to examine the greenhouse effect on the sustainability of human population as well as the environmental tax when the sustainability is in danger. The conclusion of this paper is that when the negative effect is small, the tax can guarantee the sustainability, where the effective tax rate interval for the sustain...

Background: Allosteric communications are vital for cellular signaling. Here we explore a relationship between protein architectural organization and shortcuts in signaling pathways. Results: We show that protein domains consist of modules interconnected by residues that mediate signaling through the shortest pathways. These mediating residues tend to be located at the inter-modular boundaries,...
