Modeling Gene Expression: Lac operon.

Gene regulation is an essential process for cell development, having a profound effect in dictating cell functions. Bacterial genes are often regulated through inducible systems like the Lac operon which plays an important role in cell metabolism. An accurate model of its regulation can reveal the dynamics of gene expression.

An Essential Hospice Experience Course for Preclinical Students.

This article proposes an undergraduate hospice experience course as a new model of experiential learning, one that would provide effective preparation for students entering medical school and that would help them become better doctors. Medical humanities scholars scrutinize narrative models for inspiration and understanding, in order to develop teaching strategies that recognize the importance of the end of life and caring for patients appropriately. The written narrative, however, should not stand alone: the spoken, or shared narrative-the story as it is told by patients, friends, and family members-is equally important.

Voices from the Newspaper Club: Patient Life at a State Psychiatric Hospital (1988-1992).

The authors conducted a qualitative analysis of thirty-seven issues of The DDU Review, a newsletter produced by residents of the Dual Diagnosis Unit, a residential unit for people who had diagnoses of developmental disability and serious mental illness in the Central State Hospital (Indiana, USA). The analysis of the newsletters produced between September 1988 and June 1992 revealed three major themes: 1) the mundane; 2) good behavior; and 3) advocacy. Contrary to the authors' expectations, the discourse of medicalization-such as relations with physicians, diagnoses, and medications-receive little attention.

An investigation of the mechanisms underlying the effects of viewing distance and stimulus length on attentional asymmetries during line bisection.

Clinical neglect patients overattend to stimuli on their right, whereas the general population overattend to the left (pseudoneglect). Both phenomena are affected by viewing distance, whereby the attentional biases are attenuated as the stimulus moves from near to far space. Both are also affected by stimulus length and reduce in strength, or even reverse (the crossover effect), as length decreases.

The content of hope in ambulatory patients with colon cancer.

Although hope is a pervasive concept in cancer treatment, we know little about how ambulatory patients with cancer define or experience hope. We explored hope through semistructured interviews with ten patients with advanced (some curable, some incurable) colon cancer at one Midwestern, university-based cancer center. We conducted a thematic analysis to identify key concepts related to patient perceptions of hope.
