Liver and kidney transplantation for polycystic disease

We conducted a double-blind, randomized, placebo-controlled study to investigate the effectiveness of P6 acupuncture on postoperative vomiting in children undergoing strabismus surgery. Acupuncture was performed by laser stimulation with a low-level laser. Laser stimulation of P6 was administered 15 min before induction of anaesthesia and 15 min after arriving in the recovery room. In the laser stimulation group, the incidence of vomiting was significantly lower (25%) than that in the placebo group (85%).     

Evolution and horizontal transfer of an entire biosynthetic pathway for cytochrome c biogenesis: Helicobacter, Deinococcus, Archae and more

A 61-year-old women receiving warfarin after mitral valve replacement experienced extensive ecchymoses after starting tramadol therapy. Laboratory values revealed critical elevations of prothrombin time and international normalized ratio. The patient's coagulation values returned to acceptable levels after discontinuing tramadol and temporarily stopping warfarin. The mechanism for this interaction is unknown. Practitioners should be aware of the possibility of such a interaction and exercise caution when tramadol is prescribed for a patient receiving warfarin.     

Using cooperative learning to enhance the academic and social experiences of freshman student athletes

One hundred seven freshman student athletes in 17 different women's and men's intercollegiate sports were required to attend evening study sessions. The student athletes completed academic assignments and studied for tests primarily in cooperative learning groups. As gauges of the program's impact on the participants, 3 questionnaires were administered to a sample of 50 (25 women and 25 men). The respondents reported that (a) they worked cooperatively on academic assignments, (b) the program staff provided both academic and personal support while structuring and facilitating cooperative learning groups, and (c) they themselves were highly task oriented, confident of their academic ability, and involved in positive and supportive relationships with their fellow participants.     

Sudden flashover of nonceramic insulators in artificialcontamination tests

This paper presents experimental and theoretical results to explain the phenomenon of sudden flashover on artificially contaminated nonceramic insulators. A sudden flashover in this paper is defined as a flashover occurring on a partially contaminated insulator, and which is preceded by little or no surface discharge activity. Sudden flashovers could occur in the field on those insulators where the wet surface resistance varies over a wide range along the insulator length. The mechanism of sudden flashover is significantly different from conventional contamination flashover that occurs in standard contamination tests. The insulators evaluated had weathersheds made from silicone and ethylene propylene diene monomer (EPDM) rubbers. The impact of the present study from the point of view of weathershed material, insulator design, development of a comprehensive laboratory test and field monitoring for evaluating the performance of nonceramic insulators in service are discussed     

Introduction to the special section: research on the nature and treatment of alcoholism--does one inform the other?

Although the 2 topics of the nature and treatment of alcoholism have both been investigated for years, they are just recently beginning to interface with and complement one another. This special section addresses the interface from both perspectives and covers content areas that touch on current issues, research and treatment trends, and controversies in the alcohol field. The first 2 articles focus on the nature of alcoholism with commentary on implications for treatment, and the second 4 articles shift to examine research on treatment of alcohol problems, with implications for understanding the nature of alcoholism. This introductory article describes the special section, summarizes the articles in the section and integrates the information to discuss areas of increasing interface between research on the nature and treatment of heterogeneous substance abuse problems.
