The microstructure change in thin NiFe/Cu/NiFe films during the magnetization process was observed by the Lorentz electronmicroscopy. TWo types of films were prepared: (1) one NiFe layer with anisotropy and the other layer without, and (2) both NiFe layershave anisotropy normal each other. The domain wall migration and magnetization rotation processes in each of NiFe layers could be observed separately. The presence of magnetic anisotropy in the magnetic layer effectively controls the behavior of magnetic domains. Theinteraction between the two NiFe layers of the film could be observed not so strong in the present experiment.

Objectives: The objective of this paper is to report students' perceptions of factors that demotivated their learning in lectures and laboratory-based skills practice ***: A total of 23 students were recruited from the Bachelor of Nursing courses at three Japanese universities,using purposive sampling.A semi-structured interview was conducted with each participant between November 2017 and January 2018 to elicit their perceptions about which aspects of the teaching context demotivated their engagement in *** results were analyzed using thematic ***: Three themes were generated: a restrictive environment,discouraging attitudes and discouraging teaching ***: To prevent students from experiencing demotivation,teachers in the nursing faculty need to manage learning resources more effectively,create a quiet and focused atmosphere to allow students to concentrate,and be enthusiastic about *** also need to add value to their classes,help students to follow lectures,and ensure that the workload they give their students is appropriate.

AIM： To investigate the efficacy of angiotensin Ⅱ receptor antagonist on hepatic stellate cells （HSCs） activation in the patients with non-alcoholic steatohepatitis （NASH）. METHODS： Seven patients with NASH were prescribed Iosartan, a selective angiotensin Ⅱ type 1 receptor antagonist （50 mg/d） for 48 wk. Liver biopsies were performed both at the entry and end of the study in all patients. Quiescent and activated HSCs were identified by double immunostaining using anti-p75 and α-smooth muscle actin antibodies, and the number of each phenotype was counted. Similarly, the liver specimens obtained from the eight patients with non-alcoholic fatty liver （NAFL） were also examined as controls. RESULTS： In NASH hepatic tissues, activated HSCs were dominantly distributed as compared with those in NAFL. The 48-wk Iosartan treatment induced a remarkable decrease in activated HSCs and a mild increase in quiescent phenotypes. CONCLUSION： Our data suggest the crucial involvement of HSCs in anti-fibrotic effect of angiotensin Ⅱ receptor antagonist on patients with NASH.

Disease suppression of Fusarium crown rot and the changes in free amino acid contents in mycorrhizal asparagus (Asparagus officinalis L., cv. “Welcome”) plants were investigated. Sixteen weeks after arbuscular mycorrhizal fungus (AMF;Glomus intraradices) inoculation, mycorrhizal plants showed higher dry weight of shoots than non-mycorrhizal plants, and AMF colonization level in a root system reached up to 73.3%. Ten weeks after Fusarium proliferatum (Fp;N1-31, SUF1207) inoculation, control plants showed 100% incidence and high severity in the 2 Fp isolates. However, AMF plants showed lower severity than non-AMF plants in the 2 Fp isolates. Ten weeks after Fp (N1-31) inoculation, the increase in 7 constituents of amino acids (glutamine, arginine, aspartic acid, alanine, citrulline, GABA, glycine) in shoots, and 9 in roots (asparagine, arginine, threonine, serine, glutamine, citrulline, valine, GABA, histidine) occurred in AMF plants. From these findings, plant growth promotion and suppression of Fusarium crown rot occurred in mycorrhizal asparagus plants, and the disease tolerance was supposed to be associated with the symbiosis-specific increase in free amino acids.

The present study was performed to clarify the influence of having a firm purpose in life (PIL) on psychological and physical stresses. Participants were 59 subjects (19 males and 40 fe- males) with a mean age of 30.9 years (standard deviation, 12.1;range, 18 - 68 years). We used a mental arithmetic (MA) test as a goaloriented stressor;the test was supposed to be finished before a time limit expired without using pencil and paper. We used a PIL test to assess the intensity of personal meaning in one’s life, an interest in mental arithmetic test (IMAT) to assess the intensity of interest in the MA test, and an anxiety inventory (AI) to assess the anxiety level of before and during the MA test. Heart rate (HR), systolic blood pressure (SBP), diastolic blood pressure (DBP) and nose tip temperature (NTT) were recorded before and after MA. We used logistic regression modeling to estimate the odds ratio (OR) of independent variables of age, sex, PIL test score, AI score, HR, SBP, DBP, and NTT before the MA test. Multivariate-adjusted models showed that PIL test scores prior to the MA test significantly predicted the observed changes in AI score and HR. Other variables were not significant predictors. In conclusion, we found that a firm PIL decreased anxiety under psychological stress as measured with the MA test, even with objective evaluation by others. Having a firm PIL also lowered the response of the sympathetic nervous system to psych0logical stress.

Sir,We have reported two patients with hepatocellular carcinoma(HCC)and type 2 diabetes mellitus(T2DM),who showed abundant glycogen in their liver parenchyma but a marked reduction of glycogen content in HCC.[1]It was suggested that the latter was associated with appearance of a Warburg type glycolysis[1]and discussed in some detail.[2]
