Abstract
INTRODUCTION Award schemes and self-evaluation systems have been developed to implement the 'Health-Promoting School (HPS)' concept in European and Asian countries. While there have been many successes in these regions, the implementation of HPS in African countries has been minimal. This study evaluated the impact of a self-evaluation system on school health in Niger. METHODS A school health activity guide was developed and distributed to 1999 primary schools in the Niger Tahoua region to raise awareness and solve problems related to school health and hygiene. The number of schools that planned or implemented health-related activities, and the budget and implementation status of their activities was compared over 3 years (before, soon after, and 1 year after distribution). Focus group discussions (FGDs) were also conducted targeting Conseillers Pédagogiques (CPs), who supervise primary schools and teachers, primary school principals and members of Comité de Gestion des Etablissement Scolaire (COGES), which is a type of school steering committee. RESULTS The number of schools planning at least one health-related activity increased from 47% to 79% soon after distribution of the guide (p <0.001).The number of schools implementing activities increased from 44% to 65% one year after distribution (p <0.001). Health-related budget per school also increased after distribution (p <0.0001) and increases were maintained 1 year after the intervention (p=0.8414). Fulfilment or partial fulfilment rates for health-related activities were lower compared with other (non-health) activities in all three years (80%, 77% & 84% in health-related activities vs 88%, 90% & 91% in others; p <0.001, p <0.001, & p=0.004, respectively). Most FGD participants expressed a positive impression of the program and noted the usefulness of the guide. However, some respondents reported difficulties, especially in relation to budget. CONCLUSION The introduction of a health activity guide for self-assessment was effective in increasing health-related activities in primary schools in Niger, where a simple monitoring system should be introduced to establish the HPS concept.

Abstract
Cerebral event is the 2nd leading cause of mortality and morbidity after cardiac surgery. Therefore, management of cerebrovascular disease is essential to improve the outcome. We reviewed the literatures and cases in our institute to present the current strategy for these patients. Firstly, for the patients in high risk of stroke, if patients undergo coronary artery bypass grafting (CABG), off-pump CABG (OPCAB) with aorta non-touch technique is recommended. We experienced no intraoperative stroke in our recent consecutive 1,000 cases. If patients require cardiopulmonary bypass, keeping blood pressure high during bypass may prevent local hypoperfusion in brain. Second, for the patients having carotid artery disease, the team approach with neurologists is essential to determine to precede either of cardiac surgery or carotid endoarterectomy. Because preceding carotid endoarterectomy gives the best result to prevent stroke, these patients had better have carotid endoarterectomy first, unless there is indication of urgent cardiac surgery. Third, for the patients with active endocarditis, early indication of surgery is recently recommended, unless patients have intracranial hemorrhage. Recent magnetic resonance imaging (MRI) examination revealed more than 60% of patients have stroke regardless of size, therefore, team approach with neurologists is important to decide the timing of the surgery. Team approach and correct selection of procedural technique are important to prevent cerebrovascular events during cardiac surgery.

Abstract
Photosynthetic bacteria produce hydrogen from lactate and acetate that are products of hydrogen producing bacteria in the dark. Thus, their coculture is a promising method for hydrogen production. However, the hydrogen production yield from acetate of Rhodobacter sphaeroides RV, which has been shown to possess the highest yield and hydrogen production rate, is low as compared to that from lactate. Photosynthetic bacteria that produce hydrogen from acetate as well as lactate were screened from lakes and swamps in the Tokyo and Chiba areas in Japan. Seventy-six strains of photosynthetic bacteria were obtained and the analysis of their 16S rRNA gene sequences revealed that they belong to R. sphaeroides. Among the isolated bacteria, R. sphaeroides HJ produced the highest amount of hydrogen from acetate and lactate. The HJ strain produced a 2300±93ml/L-broth of hydrogen from 75mM acetate consumed during for 120h of fermentation. The amount of hydrogen and the yield from acetate were 1.9 and 2.1 times higher, respectively, than those of R. sphaeroides RV. The amount and yield of hydrogen, produced by R. sphaeroides HJ from lactate were similar to those produced by R. sphaeroides RV. Since the amount and yield of produced hydrogen by the HJ strain were similar regardless of the substrate (acetate or lactate), its metabolic pathway could have a key to increasing hydrogen production from acetate.

Abstract
We describe a tunable two-color CW light source sufficient for realizing a coherent Raman transfer between two molecular states that are more than 0.5 eV (120 THz) apart. The simultaneous frequency stabilization of 901 nm and 655 nm light was achieved by locking diode lasers to a single ultralow expansion cavity with dual wavelengths coating. By utilizing offset-locking and optical phase-locked loop (OPLL), we ensured a large mode-hop free tuning range (> 2 GHz). The obtained short term linewidth (<10 Hz) and the linear drift of frequency (65 mHz/s) were both sufficient to eliminate the influence of laser linewidths on the efficiency of coherent Raman transition.

Abstract
We report on the direct conversion of laser-cooled 41K and 87Rb atoms into ultracold 41K87Rb molecules in the rovibrational ground state via photoassociation followed by stimulated Raman adiabatic passage. High-resolution spectroscopy based on the coherent transfer revealed the hyperfine structure of weakly bound molecules in an unexplored region. Our results show that a rovibrationally pure sample of ultracold ground-state molecules is achieved via the all-optical association of laser-cooled atoms, opening possibilities to coherently manipulate a wide variety of molecules.

Abstract
Background The relationship between plasma angiopoietin-like protein 3 (ANGPTL3), and lipoprotein lipase (LPL) activity and hepatic triglyceride lipase (HTGL) activity has not been investigated in the metabolism of remnant lipoproteins (RLPs) and high-density lipoprotein (HDL) in human plasma. Methods ANGPTL3, LPL activity, HTGL activity, RLP-C and RLP-TG and small, dense LDL-cholesterol (sd LDL-C) were measured in 20 overweight and obese subjects in the fasting and postprandial states. Results Plasma TG, RLP-C, RLP-TG and sd LDL-C were inversely correlated with LPL activity both in the fasting and postprandial states, but not correlated with HTGL activity and ANGPTL3. However, plasma HDL-C was positively correlated with LPL activity both in the fasting and postprandial states, while inversely correlated with HTGL activity. ANGPTL3 was inversely correlated with HTGL activity both in the fasting and postprandial states, but not correlated with LPL activity. Conclusion HTGL plays a major role in HDL metabolism, but not RLP metabolism. These findings suggest that ANGPTL3 is strongly associated with the inhibition of HTGL activity and regulates HDL metabolism, but not associated with the inhibition of LPL activity for the metabolism of RLPs in human plasma.

Abstract
Recurrence is frequently associated with the acquisition of radioresistance by tumors and resulting failures in radiotherapy. We report, in this study, that long-term fractionated radiation (FR) exposures conferred radioresistance to the human tumor cells, HepG2 and HeLa with cyclin D1 overexpression. A positive feedback loop was responsible for the cyclin D1 overexpression in which constitutively active AKT was involved. AKT is known to inactivate glycogen synthase kinase-3beta (GSK3beta), which is essential for the proteasomal degradation of cyclin D1. The resulting cyclin D1 overexpression led to the forced progression of S-phase with the induction of DNA double strand breaks. Cyclin D1-dependent DNA damage activated DNA-dependent protein kinase (DNA-PK), which in turn activated AKT and inactivated GSK3beta, thus completing a positive feedback loop of cyclin D1 overproduction. Cyclin D1 overexpression led to the activation of DNA damage response (DDR) consisted of ataxia telangiectasia mutated (ATM)- and Chk1-dependent DNA damage checkpoint and homologous recombination repair (HRR). Long-term FR cells repaired radiation-induced DNA damage faster than non-FR cells. Thus, acquired radioresistance of long-term FR cells was the result of alterations in DDR mediated by cyclin D1 overexpression. Inhibition of the AKT/GSK3beta/cyclin D1/Cdk4 pathway by the AKT inhibitor, Cdk4 inhibitor or cyclin D1 targeting small interfering RNA (siRNA) suppressed the radioresistance. Present observations give a mechanistic insight for acquired radioresistance of tumor cells by cyclin D1 overexpression, and provide novel therapeutic targets for recurrent radioresistant tumors.

Abstract
The lipid modifications which occur on Bombyx mori Ras proteins BmRas1, BmRas2 and BmRas3 were studied by metabolic labelling in an insect cell-free protein synthesis system and in a baculovirus expression system, using specific inhibitors of protein prenylation and protein palmitoylation. In addition, the subcellular localization of BmRas proteins was examined using EGFP fusion proteins of constitutively active forms of BmRas proteins transiently expressed in Sf9 cells. As a result, it was revealed that the three B. mori Ras proteins BmRas1, BmRas2 and BmRas3 are neither farnesylated nor palmitoylated but are geranylgeranylated for localization to the plasma membrane of insect cells. Thus, the mechanism of membrane binding of insect Ras proteins is quite different from that reported for mammalian Ras proteins.
