Some physical parameters controlling cell size during the evolution of the procaryons.

Possible factors controlling cell size during the evolution of unicellular organisms have been examined. It has been shown that considerations of osmotic and membrane pressure eqilibria will predict minimal cell sizes which are in good agreement with those found in present day microorganisms. It has also been shown that the possibility of random proton 'noise' would not be a limiting factor for even the smallest organisms or structures. Maximum cell size would be governed by the requirements of diffusion and transport within the cell.

Symptom experiences of lung transplant recipients: comparisons across gender, pretransplantation diagnosis, and type of transplantation.

PURPOSES: To investigate symptom experiences of patients who have single and bilateral-sequential lung transplantation and to determine whether differences exist according to gender, pretransplantation diagnosis, and type of transplantation procedure. DESIGN AND METHODS: In the context of a descriptive, comparative survey design, surviving recipients of single and bilateral-sequential lung transplants (n = 56) were mailed a symptom frequency and distress questionnaire. The response rate was 85.7% (n = 48). The average time since the recipients' lung transplantations was 1.5 +/- 0.7 years. RESULTS: Recipients of lung transplants reported that several symptoms (eg, muscle weakness, shortness of breath with activity, and changed appearance) were both frequently occurring and quite distressing. Other symptoms were identified as being distressing, but not frequently occurring, or vice versa. Significant (P <.05) differences were found for symptom experiences among pretransplant diagnostic groups and between genders and types of transplant procedures. CONCLUSIONS: These findings elucidate the symptom experiences of recipients of lung transplants and suggest that subgroup differences exist. The data provide a basis for strengthening patient and family education and for developing symptom management strategies. Further investigation of the symptom experiences of the recipients of lung transplants is needed, especially in relation to subgroups.

Planimetry study of the percent of body surface represented by the hand and palm: sizing irregular burns is more accurately done with the palm.

Sizing irregular burns is commonly done with use of the patient's hand as a template representing 1% of the body surface. To verify that this is accurate over a broad range of ages or to see if the surface of the palm is a more consistent template, a planimetry study was done. This revealed that the surface area of the palm averaged 0.52% total body surface area (+/- 0.07) and the palmar surface of the hand 0.85% total body surface area (+/- 0.08). The surface of the palm was a more consistent template and represented 0.5% of the body surface over a broad range of ages.

Absence of antisperm antibodies in anejaculatory men.

Antisperm antibodies were assessed in the serum samples of 73 men unable to ejaculate naturally and on the sperm cells of 13 of these men. None of the serum samples were found to be positive by sperm agglutination or sperm immobilization methods and antibodies were detected by an immunobead assay on the sperm cells of one of the 13 men examined.

Intraosseous infusion.

Intraosseous infusion is recommended for children aged 6 years or less who have life-threatening conditions and require vascular access which cannot be achieved in a timely manner via another route. It is a reliable, safe procedure with a complication rate of less than 1%.
