Gene targeting in mice, first reported 25 years ago, has led to monumental advances in the understanding of basic biology and human disease. The ability to employ a similarly straightforward method for gene manipulation in other experimental organisms would make their already significant contributions all the more powerful. Here, we briefly outline the strengths and weaknesses of reverse genetics techniques in non-murine model organisms, ending with a more detailed description of two that promise to bring targeted gene modification to the masses: zinc finger nucleases (ZFNs) and transcription activator-like effector nucleases (TALENs).

A qualitative design based on the phenomenographic approach was chosen to describe the patients' conceptions of their life situation. Fourteen patients-eight men and six women, aged 21-84-were strategically selected to obtain as broad a variation as possible.

The aim of this study was to document the social class distribution of 12 common chronic conditions in middle-aged persons in Dublin. Data were collected on 3,111 individuals attending three large general practices over the course of a calendar year, and 1,024 individuals living in the same areas.

Visiting rates were substantially different between practices and between GMS and private patients. However, GMS patients were older and had 50% more chronic illnesses.

The prevalence of the following conditions were measured: coronary heart disease, hypertension, stroke, diabetes, asthma, chronic bronchitis, rheumatic disorders, dyspepsia, depression, anxiety disorders, psychoses, and cancer. In order to obtain a valid denominator for the study a second community based study was carried out in the same areas to determine what proportion of persons visit their general practitioner over the course of a year.
