Ionic liquids from cationic palladium(II) chelate complexes: preparation, thermal properties, and crystal structures

A non-fatal accident with a CGR-Sagittaire accelerator in the Dr Daniel den Hoed Cancer Center (DDHCC) in Rotterdam in 1988 is described. In a period with frequently occurring technical problems, a patient, undergoing fractionated treatment at this accelerator for prostatic cancer, developed severe skin reactions on the right half ventr

The effect of somatostatin analogue on glucose homeostasis in conscious dogs

Our aim was to clarify the effect of a somatostatin analogue (octreotide) on glucose flux in conscious dogs. We monitored the effects with catheters in the portal vein, hepatic vein and femoral artery and Doppler flow probes on the portal vein and hepatic artery before and after oral glucose administration. A significant increase of portal vein plasma flow after oral glucose was completely suppressed by both 4 and 1 &#956;g/kg octreotide. All doses of octreotide (4, 1 and 0.1 &#956;g/kg) suppressed the glucose-induced increment of arterial glucose by dose response. Only 4 &#956;g/kg of octreotide slightly but significantly suppressed hepatic glucose output. Marked suppression and delayed glucose absorption by the intestine was observed after 4 &#956;g/kg of octreotide. One and 0.1 &#956;g/kg octreotide also suppressed glucose absorption without delayed absorption. Total amounts of absorbed glucose during 3h after oral glucose were 24 ± 11% with 4 &#956;g/kg of octreotide, 37 ± 16% with 1 &#956;g/kg of octreotide, and 48 ± 8% with 0.1 &#956;g/ kg of octreotide, all of which were significantly less than that of the control (73 ± 8%). Using 4 &#956;g/kg of octreotide treatment, the liver took up only 5 ± 4% of the absorbed glucose, while the liver took up 35 ± 6% and 43 ± 9% of the absorbed glucose with 1 and 0.1 &#956;g/kg of octreotide. These latter values were similar to that of the control value of 34 ± 4%. In conclusion, we found that octreotide administered before oral glucose had a remarkable stabilizing effect on postprandial glycemic surges. Both the direct inhibitory effect of octreotide on portal vein plasma flow and impaired glucose absorption would contribute to this decreased postprandial hyperglycemia, while its suppressive effect on other hormones, such as insulin and glucagon, did not seem to influence the reduction of hyperglycemia.</p

Bystander CPR means that people who find cardiopulmonary arrest perform cardiopulmonary resuscitation on the spot. Quick CPR contributes to increase in the rate of returning to the society as well as one-month survival rate and neurological prognosis. We report our experience with two high school students who underwent quick Bystander CPR, avoided sudden death, and returned to the society. ［Case 1］ Eighteen-year-old man : He collapsed suddenly in his home. Bystander CPR was performed by his family until emergency crews arrived there. Automated external defibrillator （AED） worked twice and his heartbeat started again. In electrocardiogram, coved type ST elevation in lead V1 was observed, and he was diagnosed as Brugada syndrome. We implanted an implantable cardioverter-defibrillator. Since his condition was stable, he was discharged on the 19th day. ［Case 2］ Seventeen-year-old woman : She collapsed suddenly walking with her family. Her father confirmed that she had no response, and started Bystander CPR. Her father got AED quickly and AED worked once, and she started to breathe again. She was admitted to our hospital for a work-up. Torsades de pointes （TdP） was observed in monitor electrocardiogram, and her QTc time was 513 msec in 12‐lead electrocardiogram. She was diagnosed as congenital long QT syndrome because genetic test showed that she had LQT2. Her QTc time was improved （approximately 350 msec） by medication, and she was discharged on the 25th day. Utstein-style statistics in Japan shows that the rate of returning to the society can be doubled by performing Bystander CPR on patients with cardiopulmonary arrest. However, performing rate of Bystander CPR is less than 50％ in Japan. In order to increase survival rate of patients with cardiopulmonary arrest for the future, it is important to inform people about CPR and to promote CPR, and in fact, we have been promoting CPR

Fabrication of high-concentration Cu-doped deuterated targets for fast ignition experiments

In high-energy-density physics, including inertial fusion energy using high-power lasers, doping tracer atoms and deuteration of target materials play an important role in diagnosis. For example, a low-concentration Cu dopant acts as an x-ray source for electron temperature detection while a deuterium dopant acts as a neutron source for fusion reaction detection. However, the simultaneous achievement of Cu doping, a deuterated polymer, mechanical toughness and chemical robustness during the fabrication process is not so simple. In this study, we report the successful fabrication of a Cu-doped deuterated target. The obtained samples were characterized by inductively coupled plasma optical emission spectrometry, differential scanning calorimetry and Fourier transform infrared spectroscopy. Simultaneous measurements of Cu K-shell x-ray emission and beam fusion neutrons were demonstrated using a petawatt laser at Osaka University.Ikeda T., Kaneyasu Y., Hosokawa H., et al.

The Japanese space gravitational wave antenna; DECIGO

DECi-hertz Interferometer Gravitational wave Observatory (DECIGO) is the future Japanese space gravitational wave antenna. DECIGO is expected to open a new window of observation for gravitational wave astronomy especially between 0.1 Hz and 10 Hz, revealing various mysteries of the universe such as dark energy, formation mechanism of supermassive black holes, and inflation of the universe. The pre-conceptual design of DECIGO consists of three drag-free spacecraft, whose relative displacements are measured by a differential Fabry– Perot Michelson interferometer. We plan to launch two missions, DECIGO pathfinder and pre- DECIGO first and finally DECIGO in 2024

DECIGO pathfinder

DECIGO pathfinder (DPF) is a milestone satellite mission for DECIGO (DECi-hertz Interferometer Gravitational wave Observatory) which is a future space gravitational wave antenna. DECIGO is expected to provide us fruitful insights into the universe, in particular about dark energy, a formation mechanism of supermassive black holes, and the inflation of the universe. Since DECIGO will be an extremely large mission which will formed by three drag-free spacecraft with 1000m separation, it is significant to gain the technical feasibility of DECIGO before its planned launch in 2024. Thus, we are planning to launch two milestone missions: DPF and pre-DECIGO. The conceptual design and current status of the first milestone mission, DPF, are reviewed in this article

Human PSF concentrates DNA and stimulates duplex capture in DMC1-mediated homologous pairing

PSF is considered to have multiple functions in RNA processing, transcription and DNA repair by mitotic recombination. In the present study, we found that PSF is produced in spermatogonia, spermatocytes and spermatids, suggesting that PSF may also function in meiotic recombination. We tested the effect of PSF on homologous pairing by the meiosis-specific recombinase DMC1, and found that human PSF robustly stimulated it. PSF synergistically enhanced the formation of a synaptic complex containing DMC1, ssDNA and dsDNA during homologous pairing. The PSF-mediated DMC1 stimulation may be promoted by its DNA aggregation activity, which increases the local concentrations of ssDNA and dsDNA for homologous pairing by DMC1. These results suggested that PSF may function as an activator for the meiosis-specific recombinase DMC1 in higher eukaryotes

Feasibility pilot study of a Japanese teaching kitchen program

BackgroundThis pilot study examined the feasibility of a new lifestyle modification program involving a “Teaching Kitchen” in Japan. Our goal was to explore (1) feasibility of the program; (2) acceptability for class frequency (weekly vs. bi-weekly); and (3) changes in biometrics, dietary intakes, and lifestyle factors.MethodsA total of 24 employees with obesity in a Japanese company were recruited. Participants were randomly divided into two groups (weekly or bi-weekly group), each attending the program consisting of four two-hour classes (lectures on nutrition, exercise, mindfulness, and culinary instructions). Participants were observed for changes in dietary intakes, biometrics, and health related quality of life over the subsequent 3 months. We tested the between-group differences in changes using linear mixed-effect models.ResultsThe program completion rates were 83.3% in total (91.7% for weekly group and 75.0% for bi-weekly group). From baseline to post-intervention, significant decreases were observed in weight (p &lt; 0.001), body mass index (p &lt; 0.001), diastolic blood pressure (p = 0.03), body fat mass (p &lt; 0.001), and dietary intakes in total fat (p = 0.03) and sodium (p = 0.008) among 17 participants who were available for measurements. Improvements in biometrics remained significant 1 month after the intervention (all p ≤ 0.03 in 14 participants). Participants' health related quality of life was significantly improved in bodily pain, general health, vitality, and mental component score (all p ≤ 0.047).ConclusionsThe new Japanese Teaching Kitchen program is feasible with high program completion rates in Japanese office workers with obesity. While this was a small feasibility study, significant multiple improvements in dietary intakes, biometrics, and health related quality of life suggest that this line of inquiry warrants further exploration to address obesity and obesity-related diseases in Japan
