Abstract. The acute castrate ram (wether) was used as an experimental model to investigate the site(s) of feedback on luteinizing hormone (LH) by testosterone, dihydrotestosterone and oestradiol. At the time of castration, wethers were implanted subdermally with Silastic capsules containing either crystalline testosterone (three 30 cm capsules), dihydrotestosterone (five 30 cm capsules) or oestradiol (one 6.5 cm capsule). Blood samples were taken at 10 min intervals for 6 h 2 weeks after implantation to determine serum steroid concentrations and to characterize the patterns of LH secretion. Pituitary LH response to exogenous LRH (5 ng/kg body weight) were also determined at the same time. The steroid implants produced serum concentrations of the respective hormones which were either one-third (testosterone) or two-to-four times (dihydrotestosterone, oestradiol) the levels measured in rams at the time of castration. Non-implanted wethers showed rhythmic pulses of LH (pulse interval 40–60 min) and had elevated LH levels (16.1 ± 1.6 ng/ml; mean ± se) 2 weeks after castration. All three steroids suppressed pulsatile LH release and reduced mean LH levels (to below 3 ng/ml) and pituitary LH responses to LRH. Inhibition of pulsatile LH secretion by all three steroids indicated that testosterone as well as its androgenic and oestrogenic metabolites can inhibit the LRH pulse generator in the hypothalamus. Additional feedback on the pituitary was indicated by the dampened LH responses to exogenous LRH.

In this paper, we investigate the geometric phase of the field interacting with a moving four-level atom in the presence of Kerr medium. The results show that the atomic motion, the field-mode structure and Kerr medium play important roles in the evolution of the system dynamics. As illustration, we examine the behavior of the geometric phase and entanglement with experimentally accessible parameters. Some new aspects are observed and discussed.

Abstract Introduction An institutional Burn Intensive Care Unit (ICU) Rounding Tool was implemented for both quality improvement data collection and trainee education. Forms are completed by trainee team members daily for all critically ill patients prior to teaching rounds. Gathered data are structured to facilitate evaluation of patient volume status, sepsis risk and ventilator management. The forms are then used to guide discussion among students, residents, mid-level providers, fellows, attending surgeons and other members of the multi-disciplinary rounding team. We conducted a series of interviews with trainees regarding their user experience to assess the tool’s educational utility. Methods A convenience sample of residents who had recently completed their Burn Surgery rotation were interviewed in a structured format. Questions focused on the form’s ease of use and comprehensibility. Emphasis was placed on the extent to which it stimulates learning while rounding. Additional feedback was sought for the purpose of improving the tool for continued use. Results Participants were post-graduate year one or two resident physicians training in General Surgery, Urology, Emergency Medicine or Anesthesia. Prior experience and comfort with ICU level care ranged from very little to moderate. All interviewees found the tool helpful in their patient assessments, though the current layout of the form was a frustration for many. Overall, they unanimously found the forms beneficial for preparation of patient presentations and felt that utilization during rounds facilitated learning. Conclusions Interviews with trainees on their burn surgery rotation demonstrate that implementation of an ICU Rounding Tool has provided educational benefit, particularly for those less experienced in intensive care. Feedback from this cohort will be used to improve the tool’s usability. Our next steps will include a more formal survey of all trainees involved since the inception of this project.
