    Abstract Aim: This study aimed to identify senior nurses' expectations and support of new graduate nurses' adjustment to their work environment.
    Background: New graduate nurses have difficulties in adjusting to their work environment because they are not well prepared for clinical nursing practice upon graduation. Hospitals support their adjustment to their work environment through residency/transition programs. Although such support exists, new graduate nurses are expected to learn the expected behavior and attitude themselves. Thus, identifying senior nurses' expectations and support of new graduate nurses' adjustment may facilitate smooth adjustment to the work environment.
    Design: This was a qualitative descriptive study.
    Methods: Fourteen nurses who teach new graduate nurses in Japanese hospitals were interviewed face-to-face individually. The data were analyzed using qualitative inductive content analysis, which was coded and sorted to identify categories.
    Results: Regarding senior nurses' expectations of new graduate nurses' adjustment, six categories emerged: trying to fit in with people in their ward, behaving by following the unspoken rules of their ward, having attitudes compatible with learning, addressing their situations using their initiative, showing a willingness to learn, and obtaining necessary information by themselves. Senior nurses' support of new graduate nurses' adjustment consisted of four categories: watching over and speaking to them, trying to create a good working environment, encouraging them to have attitudes compatible with learning, and teaching them how to learn.
    Conclusions: Senior nurses need to understand and express what they expect from new graduate nurses at the stage of hospital adjustment. If senior nurses understand their expectations for adjustment, they can help new graduate nurses effectively. Furthermore, understanding the expectations of senior nurses may facilitate new graduate nurses' adjustment. These findings may contribute to good working relationships between senior and new graduate nurses.

    Abstract We examined the causes of decreased fingertip dexterity in elderly individuals with an aim to improve their quality of life by improving their activities of daily living. We calculated nerve conduction velocity, absolute error during force adjustment tasks, and fingertip dexterity test scores for 30 young (21-34 years old) and 30 elderly (60-74 years old) participants to identify age-related changes. We also assessed subjective complaints of pain, motor function, and numbness. Motor nerve (young: 55.8 ± 3.7 m/s; elderly: 52.2 ± 5.0 m/s) and sensory nerve (young: 59.4 ± 3.4 m/s; elderly: 55.5 ± 5.3 m/s) conduction velocities decreased in an age-dependent manner. Moreover, the decrease of motor nerve conduction velocity was associated with decreased fingertip dexterity (objective index), while the decrease of sensory nerve conduction velocity was associated with subjective complaints of pain and motor function (subjective index).

    Abstract We succeeded in controlling the crystal structure of osmium (Os) nanoparticles (NPs). Although Os adopts only a hexagonal close-packed (hcp) structure in the bulk state, a face-centred cubic (fcc) Os was synthesized by a chemical reduction method using an Os acetylacetonate complex as a precursor.

    Abstract Green tea polyphenols, particularly catechins, decrease fasting and postprandial glucose. However, no studies have compared the timing of green tea ingestion on glucose metabolism and changes in catechin concentrations. Here, we examined the effects of timing of acute catechin-rich green tea ingestion on postprandial glucose metabolism in young men. Seventeen healthy young men completed four trials involving blood collection in a fasting state and at 30, 60, 120, and 180 min after meal consumption in a random order: 1) morning placebo trial (09:00 h; MP trial), 2) evening placebo trial (17:00 h; EP trial), 3) morning catechin-rich green tea trial (09:00 h; MGT trial), and 4) evening catechin-rich green tea trial (17:00 h; EGT trial). The concentrations of glucose at 120 min (P=.031) and 180 min (P=.013) after meal intake were significantly higher in the MGT trials than in the MP trials. Additionally, the concentration of glucose was significantly lower in EGT trials than in the EP trials at 60 min (P=.014). Moreover, the concentrations of glucose-dependent insulinotropic polypeptide were significantly lower in the green tea trials than in the placebo trials at 30 min (morning: P=.010, evening: P=.006) and 60 min (morning: P=.001, evening: P=.006) after meal intake in both the morning and evening trials. Our study demonstrated that acute ingestion of catechin-rich green tea in the evening reduced postprandial plasma glucose concentrations.

    Abstract Aim: The purpose of this study was to explore the strategies used by nurse managers in Japan to facilitate the integration of newly graduate nurses (NGNs) into their clinical units.
    Background: The integration of NGNs into clinical units is an important issue for both NGNs and nurse managers because the first year of practice plays a vital role in a NGN's career.
    Method: Data were generated through semi-structured interviews with 9 nurse managers in 9 acute care hospitals. Data analysis was conducted using a qualitative content analysis method.
    Results: Nurse managers used a total of 6 strategies: understanding the circumstances of NGNs, providing opportunities for experience and learning, supporting nurses who teach NGNs, facilitating self-learning, promoting awareness of being a nurse in the clinical unit, and strengthening the sense of comradeship in clinical units. Three of these strategies were particularly important for NGNs' integration into clinical units: facilitating self-learning, promoting awareness of being a nurse in the clinical unit, and strengthening the sense of comradeship in clinical units. These strategies were described in this study.
    Conclusions: The strategies adopted by nurse managers should be aimed at all nurses, not just NGNs, in order to strengthen the sense of comradeship in clinical units. This approach would create a supportive environment for the integration of NGNs into clinical units. The strategies presented in this study can be utilized not just by nurse managers but all senior nurses in the unit. NGNs can use these strategies to help them understand what they need to do to become a full member of their unit.

    Abstract We have developed a laser Doppler velocimeter (LDV) for measuring velocity distributions in blood vessels. We converted a transmission-based LDV into a reflection-based LDV to make it suitable for clinical applications. The velocity distribution image of a serpentine flow channel obtained could be qualitatively explained by the numerical results. Finally, we evaluated the system by using it to measure injection of blood into a glass tube by a syringe pump. The results obtained demonstrate that erythrocytes can be used as seeding particles for the reflection-type micro multipoint LDV. The results obtained are useful as basic data for clinical applications.

    Abstract A 49-year-old woman with recurrent ovarian cancer clear cell carcinoma was treated by etoposide. The recurrence was found seven months after second operation. The etoposide (50 mg/day per os) was first given for 2 weeks and then etoposide (25 mg/day per os) for 4.5 months. After one month of treatment the target tumor mass was reduced in size, and the therapy was continued for 4 months in our Outpatient Department. A partial response was confirmed by B-Scope, and the tumor marker CA-125 was reduced to 15 U/ml from 210 U/ml before treatment. No side effects were observed in the patient. This case suggests that etoposide might be effective for recurrent ovarian cancer and the whole treatment course could be handled in the Outpatient Department.

    Abstract Elevated postprandial hyperglycaemia and oxidative stress increase the risks of type 2 diabetes and CVD. Green tea catechin possesses antidiabetic properties and antioxidant capacity. In the present study, we examined the acute and continuous effects of ingestion of catechin-rich green tea on postprandial hyperglycaemia and oxidative stress in healthy postmenopausal women. Participants were randomly assigned into the placebo (P, n 11) or green tea (GT, n 11) group. The GT group consumed a catechin-rich green tea (catechins 615 mg/350 ml) beverage per d for 4 weeks. The P group consumed a placebo (catechins 92 mg/350 ml) beverage per d for 4 weeks. At baseline and after 4 weeks, participants of each group consumed their designated beverages with breakfast and consumed lunch 3 h after breakfast. Venous blood samples were collected in the fasted state (0 h) and at 2, 4 and 6 h after breakfast. Postprandial glucose concentrations were 3 % lower in the GT group than in the P group (three-factor ANOVA, group × time interaction, P< 0·05). Serum concentrations of the derivatives of reactive oxygen metabolites increased after meals (P< 0·05), but no effect of catechin-rich green tea intake was observed. Conversely, serum postprandial thioredoxin concentrations were 5 % higher in the GT group than in the P group (three-factor ANOVA, group × time interaction, P< 0·05). These findings indicate that an acute ingestion of catechin-rich green tea has beneficial effects on postprandial glucose and redox homeostasis in postmenopausal women.
