Sound generated in a ward can be classified into 1) generated by medical staff, 2) generated by patients and their visitors, and 3) others, such as from in-hospital broadcasting microphones and nurse calls. Among these sounds, the incidence from medical staff, in particular, is reportedly high. The study objective is to investigate whether sound awareness is effective in regulating the sound environment even in a busy situation, such as in a real clinical setting, and to examine the extent to which sound awareness affects sound level. Nursing students were asked to perform a series of nursing activities in a pseudo-ward, and the changes in the sound level generated during the nursing activities with or without time and sound awareness were examined. Under varying experimental conditions, the sound and time levels associated with the nursing activities were measured in the following order: condition 1, without sound or time awareness;condition 2, with time awareness but without sound awareness;and condition 3, with both sound and time awareness. The time to perform nursing activities was longer with sound awareness. However, when aware of time only, the sound level from nursing activities rose by 2.3 dB, whereas when aware of both time and sound, the sound level dropped by 3.0 dB. With both time and sound awareness, there is a distinct drop in the sound level from nursing activities, such as wagon handling, handling of items (trays, bowls), working at the sink, and opening and closing the microwave oven door. These results suggest that even in a pseudo-clinical setting it is possible to regulate the environmental sound through the environmental sound awareness of the medical staff, resulting in a drop in the sound level generated while performing nursing activities.

Camouflage Therapy for Post-Inflammatory Hyperpigmentation on the Face Caused by Fixed Drug Eruption

引用

Journal of Cosmetics, Dermatological Sciences and Applications 2013年第3期3卷 8-10页

作者： tomoko Kayama Hiroko Fujii Miki Tanioka Yoshiki Miyachi Department of Dermatology Kyoto University Graduate School of Medicine Kyoto Japan

Camouflage therapy has been used for permanent contour and pigmentary defects including telangiectasias, vitiligo, lentigines, nevi, atrophic scars and burn scars. The goal of the therapy is to provide new and innovative ways to normalize the appearance of patients with abnormalities. A variety of cosmetic techniques are used to assist these patients in making their irregularities as inconspicuous as possible. Post-inflammatory hyperpigmentation is a frustrating problem afflicting many dermatology patients, particularly on the face. Here we report a case of successful cosmetic camouflage using the theory of complementary colors of light in a patient with post-inflammatory hyperpigmentation of the face caused by fixed drug eruption. Our case report supports the idea that camouflage for patients with post-inflammatory hyperpigmentation on the face caused by fixed drug eruption improves their quality of life and also supports the idea that camouflage should be part of the after care for patients who have received patch testing.

Architectural distortion is an important ultrasonographic indicator of breast cancer. However, it is difficult for clinicians to determine whether a given lesion is malignant because such distortions can be subtle in ultrasonographic images. In this paper, we report on a study to develop a computerized scheme for the histological classification of masses with architectural distortions as a differential diagnosis aid. Our database consisted of 72 ultrasonographic images obtained from 47 patients whose masses had architectural distortions. This included 51 malignant (35 invasive and 16 non-invasive carcinomas) and 21 benign masses. In the proposed method, the location of the masses and the area occupied by them were first determined by an experienced clinician. Fourteen objective features concerning masses with architectural distortions were then extracted automatically by taking into account subjective features commonly used by experienced clinicians to describe such masses. The k-nearest neighbors (k-NN) rule was finally used to distinguish three histological classifications. The proposed method yielded classification accuracy values of 91.4% (32/35) for invasive carcinoma, 75.0% (12/16) for noninvasive carcinoma, and 85.7% (18/21) for benign mass, respectively. The sensitivity and specificity values were 92.2% (47/51) and 85.7% (18/21), respectively. The positive predictive values (PPV) were 88.9% (32/36) for invasive carcinoma and 85.7% (12/14) for noninvasive carcinoma whereas the negative predictive values (NPV) were 81.8% (18/22) for benign mass. Thus, the proposed method can help the differential diagnosis of masses with architectural distortions in ultrasonographic images.

Aged Garlic Extract Reduces ROS Production and Cell Death Induced by 6-Hydroxydopamine through Activation of the Nrf2-ARE Pathway in SH-SY5Y Cells

引用

Pharmacology & Pharmacy 2013年第1期4卷 31-40页

作者： Kohfuku Kohda Hitomi Goda Kei Itoh Keijiro Samejima tomoko Fukuuchi Graduate School of Pharmaceutical Sciences Musashino University Tokyo Japan

Many degenerative or pathological processes, such as aging, cancer and coronary heart disease, are related to reactive oxygen species (ROS) and radical-mediated reactions. We examined the effectiveness of aged garlic extract (AGE), a garlic preparation rich in water-soluble cysteinyl moieties, for protection of cells from ROS produced by 6-hydroxy-dopamine (6-OHDA) using human neuroblastoma SH-SY5Y cells. Concomitant treatment of cells with AGE (2 and 4 mg/ml) showed the dose-dependent protective effect on the cell death induced by 6-OHDA. In addition, the AGE treatment significantly suppressed the increase of ROS generation by 6-OHDA. Furthermore, the protective effect of AGE was accompanied by activation of the nuclear factor erythroid 2-related factor 2 (Nrf2)-antioxidant response element (ARE) pathway and the increase of mRNAs of heme oxygenase-1 and NAD(P)H quinone oxidoreductase 1. These two enzymes are important in the cellular antioxidant system. These results indicated that AGE protected cells from ROS damage by not only capturing ROS directly but also activating the cellular antioxidant system by stimulating antioxidant gene expression via the Nrf2-ARE pathway. The present study suggested that AGE may be useful for prevention and treatment of cell damage caused by ROS.

Variations in the mental health and sense of coherence (SOC) of new graduate nurses and the effects of SOC on variations in mental health

引用

Open Journal of Nursing 2013年第1期3卷 122-129页

作者： tomoko Takeuchi Taisuke Togari Makoto Oe Yukie Takemura Hiromi Sanada Faculty of Liberal Arts The Open University of Japan Chiba Japan Faculty of Nursing Tokyo Healthcare University Tokyo Japan Graduate School of Medicine The University of Tokyo Tokyo Japan Research Hospital The Institute of Medical Science The University of Tokyo Tokyo Japan

The current research conducted a longitudinal study of new graduate nurses at 3 times-prior to their employment as nurses and 3 months and 1 year afterward. This study yielded 3 findings. 1) The mental health of new graduate nurses significantly worsens 3 months after employment as a nurse and mental health 1 year after employment as a nurse was significantly worse than that before employment. 2) A sense of coherence (SOC) is the ability to cope with stressors, and the 3 components of SOC decreased significantly in the year after employment as a nurse. 3) The mental health of new graduate nurses was significantly affected by a low SOC and by previous diminishing of SOC. Findings suggested the importance of support to sustain and improve the mental health of new graduate nurses and the importance of approaches in the workplace to encourage the development of SOC.

Screening of the Growth-Inhibitory Effects of 168 Plant Species against Lettuce Seedlings

引用

American Journal of Plant Sciences 2013年第5期4卷 1095-1104页

作者： tomoko Takemura Emi Sakuno Tsunashi Kamo Syuntaro Hiradate Yoshiharu Fujii Biodiversity Division National Institute for Agro-Environmental Sciences Tsukuba Japan.

The methanol extracts of 168 plant species from 68 families were evaluated for their inhibitory activity against lettuce seedling elongation. Among the plant species tested, 12 species had EC50 values for radicle growth inhibition ranging from 0.01 to 5.00 mg fresh weight equivalent mL-1. Enterolobium contortisiliquum, a traditionally used herbal medicine, exhibited the strongest inhibitory activity (estimated EC50: 0.28 fresh weight equivalent mL-1). Among the 12 species, Pachysandra terminalis, Tamarindus indica, and Albizia guachapele required investigation, because only little has been reported about their chemical constituents to date. The data in the present study would be useful in finding new lead compounds for natural herbicides.

The Wheat Plastochron Mutant, fushi-darake, Shows Transformation of Reproductive Spikelet Meristem into Vegetative Shoot Meristem

引用

American Journal of Plant Sciences 2013年第12期4卷 28-36页

作者： Chikako Tahira Naoki Shitsukawa Yusuke Kazama tomoko Abe Koji Murai Department of Bioscience Fukui Prefectural University Eiheiji-cho Japan RIKEN Innovation Center Woko Japan RIKEN Nishina Center Woko Japan

In wheat plants at the vegetative growth stage, the shoot apical meristem (SAM) produces leaf primordia. When reproductive growth is initiated, the SAM forms an inflorescence meristem (IM) that differentiates a series of spikelet meristem (SM) as the branch. The SM then produces a series of floret meristem (FM) as the branch. To identify the mechanisms that regulate formation of the reproductive meristems in wheat, we have investigated a leaf initiation mutant, fushi-darake (fdk) which was developed by ion beam mutagenesis. The morphological traits were compared in wild type (WT) and fdk mutant plants grown in the experimental field. WT plants initiated leaves from SAM at regular intervals in spiral phyllotaxy, while fdk plants had 1/2 alternate phyllotaxy with rapid leaf emergence. The fdk plants have increased numbers of nodes and leaves compared with WT plants. The time interval between successive leaf initiation events (plastochron) was measured in plants grown in a growth chamber. The fdk plants clearly show the rapid leaf emergence, indicating a shortened plastochron. Each tiller in fdk plants branches at the upper part of the culm. The fine structure of organ formation in meristems of fdk plants was examined by scanning electron microscopy (SEM). The SEM analysis indicated that fdk plants show transformation of spikelet meristems into vegetative shoot meristems. In conclusion, the fdk mutant has a heterochronic nature, i.e., both reproductive and vegetative programs were simultaneously in operation during the reproductive phase, resulting in a shortened plastochron and transformation of reproductive spikelets into vegetative shoots.

Background: To what extent uric acid (UA) levels and/or metabolic syndrome (Mets) contribute to the onset of chronic kidney disease (CKD) is largely unknown. The present study explores how these two factors have an association with the new incidence of CKD. Methods: Study design is a cohort study. A total of 14,485 participants were eligible for the cross-sectional analysis on UA levels and the prevalence of Mets. Among those individuals, 8,223 participants without CKD and 4,839 without Mets were eligible for the longitudinal analysis of the new incidence of CKD. Parameters monitored were body mass index, systolic and diastolic blood pressure, serum creatinine concentration, estimated glolerular filtration rate, lipid profiles, plasma glucose, HbA1c. The primary predictor was the level of UA and Mets to explain the newly-developed CKD. The observation period was 4 years. Results: In a cross-sectional analysis, higher UA levels were associated with the greater prevalence of Mets. In addition, UA levels were associated with the numbers of the Mets constituents in both genders. In a longitudinal analysis, higher UA levels were associated with the greater rate of CKD and the greater incidence of Mets. In addition, the incidence of CKD at year 4 was influenced by the presence of hyperuricemia, but not by that of the Mets. The odd ratio (OR) to predict the CKD incidence was 1.42 (95% confidence intervals (CI), 0.52 to 3.78) in the presence of Mets alone, 2.10 (95% CI, 1.36 to 3.23) in the presence of hyperuricemia alone, and 3.56 (95% CI, 1.55 to 8.21) in the presence of both. Conclusion: Hyperuricemia has a greater association with the incidence of CKD than Mets does. Hyperuricemia complicated by Mets is additionally detrimental.

＜正＞Effects of ultra violet light （UV） irradiation on the skin physiology have been studied well. However, other effects than the skin physiology have not been investigated so much. On the other hand, visible light is reported to be most important as a zeitgeber to entrain circadian rhythms in animals. However, effects of UV on the circadian rhythms such as locomotor activity and body temperature rhythms have not been investigated well. Therefore, in this study, we examined the effects of UV irradiation on the circadian rhythms of locomotor activity and body temperature in hairless mice.
