Alcohol dehydrogenase activity and electron transport in living yeast.

1. The excretion of H(+) ions, with practically equivalent uptake of K(+) ions (from 0.1m-potassium chloride), occurs during the aerobic oxidation of ethanol. 2. Acetaldehyde and acetic acid formed at the same time are quantitatively equal to the amount of ethanol oxidized. 3. A slow uptake of K(+) ions occurs during the oxidation of acetaldehyde and a more rapid uptake during the oxidation of d-glyceraldehyde 3-phosphate. 4. The anaerobic reduction of methylene blue is studied, and the inhibitory effect of K(+) and other inorganic cations on the system demonstrated. 5. The cation requirement for equal inhibitory effect is parallel with the reciprocals of the transport affinities for the ;physiological K-carrier' (as taken from Conway & Duggan, 1958). 6. The cation inhibition of methylene blue reduction is reversed by treatment of the yeast with Teepol or by freezing-and-thawing. 7. Azide is shown to inhibit the reduction of methylene blue with intact cells. The inhibition is partially reversed by Teepol treatment and completely by freezing-and-thawing.

Framing the work: development of a renal nursing professional practice model.

In 1997, a nursing care model task group was formed to develop a framework to guide the development of the nursing care delivery system in a newly merged hospital corporation. A collective group of experienced and motivated nurses in the renal program met to develop an integrated renal nursing professional practice model. In addition it was recognized that a city-wide model involving the two acute care renal centres would be advantageous. The challenge was to clearly articulate the professional roles and relationships of nurses and nurse practitioner/clinical nurse specialists in a constantly changing environment. This process provided the opportunity to identify key trends influencing renal care and possibilities for changing practice. Networking across the corporations was enhanced, partnerships were formed, and a sense of value for the work that was being undertaken developed. The group's endeavours resulted in an integrated nursing professional practice model that emphasizes accountability and continuity and places value on therapeutic relationships. Another strength of the model is the acknowledgement of the collaborative nature of the multidisciplinary team. After two years of development, the model was implemented. A city-wide Renal Nursing Professional Practice Council has been established in order to provide leadership in evaluating the model. This will include assessing the success of implementation, impact on patient/family care, and collaborative rewards experienced by staff. Future planning will address the potential need for a multidisciplinary focus within the practice council.
