Rho factor has been purified from a strain of E. coli containing the Su78 mutation in the suA gene and assayed in another strain with an amber mutation in the suA gene. The rho from the Su78 mutant strain is present in normal amounts but has altered termination function; it does not terminate transcription at some sites that are recognized effectively by the rho factor from the isogenic wild-ty...
Objective: Attitude toward dying and death is a conceptual response, based on the individual psychosocial and cultural experiences. The present study aimed to examine the psychometric properties of the Persian version of the Multidimensional Orientation toward Dying and Death Inventory (MODDI-F) among Iranian students. Methods: Using a convenience sampling method, we selected 320 students from...
Sex differences are intrinsically interesting, particularly in the brain. When sexually dimorphic structures mediate learning, and when such learning ability is necessary to compete for mates, then such differences are best understood within the framework of sexual selection. By categorizing recent studies of sex differences in the brain by their role in mate competition, theories of sexual sel...
Thrombin activates factor VIII by proteolysis at three P1 residues: Arg372, Arg740, and Arg1689. Cleavage at Arg372 and Arg1689 are essential for procofactor activation; however cleavage at Arg740 has not been rigorously studied. To evaluate the role for cleavage at Arg740, we prepared and stably expressed two recombinant B-domainless factor VIII mutants, R740H and R740Q to slow and eliminate, ...

Using PET, Savic et al., in this issue of Neuron, found a sexually dimorphic neural response to two putative human pheromones. The specific regions activated combined with the pronounced sex difference depict a pheromonal-type brain response in humans. Here, we preview this finding and suggest that human pheromones exist.
