Chemical dynamics in proteins: the photoisomerization of retinal in bacteriorhodopsin

Chemical dynamics in proteins are discussed, with bacteriorhodopsin serving as a model system. Ultrafast time-resolved methods used to probe the chemical dynamics of retinal photoisomerization in bacteriorhodopsin are discussed, along with future prospects for ultrafast time-resolved crystallography. The photoisomerization of retinal in bacteriorhodopsin is far more selective and efficient than in solution, the origins of which are discussed in the context of a three-state model for the photoisomerization reaction coordinate. The chemical dynamics are complex, with the excited-state relaxation exhibiting a multiexponential decay with well-defined rate constants. Possible origins for the two major components are also discussed.

A scientist–practitioner's viewpoint on the admissibility of behavioral and social scientific information.

Problems in applying the Daubert (1993) test to social science evidence are discussed, and new issues are raised. In particular, the difference between the legal treatment of clinical evidence, as opposed to actuarial evidence, is discussed. The changing nature of science and the effect of societal norms on evidence requirements are noted. Questions are raised about the definition of the scientific method, and an alternative to the traditional scientific treatment of data is offered and discussed.

Barriers to intimacy: An object relations prespective.

Intimacy has rarely been discussed in the psychoanalytic literature, although clinicians recognize that problems with intimacy are universal. In this article, intimacy is defined, and the sociocultural factors that serve as obstacles to intimate relatedness are discussed. Closely examined are the intrapsychic conflicts that inhibit the development of intimacy, such as a fear of fusion, a fear of object loss, paranoid-schizoid anxieties, and sexual anxieties. Because analysts help to create an environment where problems of intimacy can best be studied, understood, and treated, implications for psychoanalytic treatment are discussed. A clinical example from the author's psychoanalytic practice is offered to illustrate some of the concepts discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved)
