Quantitative Analysis of Nursing Observation Employing a Portable Eye-Tracker

Open Journal of Nursing 2016年第1期6卷 53-61页

作者： Norie Suetsugu Masafumi Ohki tsunehisa kaku Department of Nursing Faculty of Medicine Saga University Saga Japan Department of Health Sciences Graduate School of Medical Sciences Kyushu University Fukuoka Japan

Background: Observation is an important skill for making appropriate nursing decisions and engaging in good practice. However, experts’ observation behavior and cognitive processes cannot be easily verbalized or documented in an objective and accurate manner. Quantitative analysis of the observation behavior of nurses with rich clinical experience will yield effective educational data for fostering and improving nursing students’ observation skills. Objectives: To improve nursing assessment education, the differences in the information gathering processes between clinical nurses and nursing students were analyzed by using a portable eye-tracker. Design: An experimental study. Settings: The experiment was performed at a university in Japan. Participants: The participants were 11 clinical nurses with at least 5 years of clinical experience for postoperative patients, and 10 fourth-year nursing students. Methods: In a mock hospital room, wherein we recreated a situation where a patient in postoperative day 1 was confined to a bed, participants wore an eye-tracking camera and engaged in nursing observation to make an early postoperative ambulation assessment of the patient. Participants’ gaze points and gaze fixation durations were extracted from the gaze measurement data and compared. Results: Clinical nurses had shorter observation times and gaze durations than did nursing students, and focused more on the patient chart, intravenous drip, and indwelling drain. Students gazed for longest at the measuring devices for vital signs. Conclusions: We quantitatively analyzed differences in nursing observation according to clinical experience. Although no significant difference was found in gaze points, nursing students had a greater tendency to focus on information that was numerically displayed. Nurses with clinical experience conducted observations by gazing at information that they needed to focus on the most according to the patients’ postoperative course.

Newfound physiological function of FAIM protein offers hope of novel disease-modifying therapy for Alzheimer's disease

Neural Regeneration Research 2023年第12期18卷 2677-2679页

作者： Allison RBalaj Hiroaki kaku Department of Investigative Medicine Western Michigan University Homer Stryker M.D.School of MedicineKalamazooMIUSA

Introduction of Fas apoptosis inhibitory molecule(FAIM): FAIM was originally discovered in FASresistant mouse primary B lymphocytes in 1999, and was thought of as a FAS-apoptosis inhibitor based on overexpression studies(Schneider et al., 1999). FAIM is an approximately 20 k Da intracellular protein, but a subsequent study identified an alternatively spliced form.

Distribution and relative activity of matrix metalloproteinase-2 in human coronal dentin

International Journal of Oral Science 2011年第4期3卷 192-199页

Boushell Masaru kaku Yoshiyuki Mochida Mitsuo Yamauchi Department of Operative Dentistry School of Dentistry University of North Carolina Department of Bio-Prosthodontics Medical and Dental Science Niigata University Graduate School Chuo-ku Department of Periodontology and Oral Biology Division of Oral Biology Boston University Henry M. Goldman School of Dental Medicine Center for Advanced Biomedical Research Dental Research Center School of Dentistry University of North Carolina

The presence of matrix metalloproteinase-2 （MMP-2） in dentin has been reported, but its distribution and activity level in mature human coronal dentin are not well understood. The purpose of this study was to determine the MMP-2 distribution and relative activity in demineralized dentin. Crowns of twenty eight human molars were sectioned into inner （ID）, middle （MD）, and outer dentin （OD） regions and demineralized. MMP-2 was extracted with 0.33 mol·L-1 EDTA/2 mol·L-1 guanidine-HCl, pH 7.4, and MMP-2 concentration was estimated with enzyme-linked immunoabsorbant assay （ELISA）. Further characterization was accomplished by Western blotting analysis and gelatin zymography. The mean concentrations of MMP-2 per mg dentin protein in the dentin regions were significantly different （P=0.043）： 0.9 ng （ID）, 0.4 ng （MD）, and 2.2 ng （OD）, respectively. The pattern of MMP-2 concentration was OD〉ID〉MD. Western blotting analysis detected -66 and -72 kDa immunopositive proteins corresponding to pro- and mature MMP-2, respectively, in the ID and MD, and a -66 kDa protein in the OD. Gelatinolytic activity consistent with MMP-2 was detected in all regions. Interestingly, the pattern of levels of Western blot immunodetection and gelatinolytic activity was MD〉ID〉OD. The eoneentration of MMP-2 in human coronal dentin was highest in the region of dentin that contains the dentinoenamel junction and least in the middle region of dentin. However, levels of Western blot immunodetection and gelatinolytic activity did not correlate with the estimated regional concentrations of MMP-2, potentially indicating region specific protein interactions.
