Discovery of two new supernovae and an AGN outburst by PS1
- 2010
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- We report the discovery of two spectroscopically-confirmed Supernovae PS1-1000302 and PS1-1000303, and an AGN outburst PS1-1000305 in the Pan-STARRS1 "3Pi Faint galaxy supernova survey". PS1-1000302 was detected on June 12.4 UT (g=18.5) at 16:33:43.094 +54:42:04.18 (J2000) located 1.1" from the center of the host galaxy SDSS J163343.08+544205.4. PS1-1000303 was detected on June 14.3 UT (g=19.2) at 17:11:52.827 +43:36:57.06 (J2000) located 0.4" from the center of the host galaxy SDSS J171152.82+433656.7.

- The effect of cycling on titanium nitride stability in a range of normalized steels containing additions of V, Al, and N has been investigated. Nitride dispersions and chemical analysis of individual particles are studied using transmission electron microscopy and a quantitative 200 kV STEM-EDX-EELS microanalysis system. Whereas normalized material contains nitrides of mixed compositions, only nitrides based on TiN survive high energy simulated weld cycles. Grain growth is dependent on stability, and this depends on the original composition of the nitrides. The presence of aluminum is particularly detrimental. The best gain growth control and highest toughness are found in steels based on optimum ratios of Ti/V/N and on low Al levels

- Scallops possess a visual system comprising up to 200 eyes, each containing a concave mirror rather than a lens to focus light. The hierarchical organization of the multilayered mirror is controlled for image formation, from the component guanine crystals at the nanoscale to the complex three-dimensional morphology at the millimeter level. The layered structure of the mirror is tuned to reflect the wavelengths of light penetrating the scallop’s habitat and is tiled with a mosaic of square guanine crystals, which reduces optical aberrations. The mirror forms images on a double-layered retina used for separately imaging the peripheral and central fields of view. The tiled, off-axis mirror of the scallop eye bears a striking resemblance to the segmented mirrors of reflecting telescopes.

- Nitration of barbituric acid at 40°C gave the previously unknown 5,5- dinitrobarbituric acid (3), which readily underwent hydrolysis to dinitroacetylurea (5), which in turn could be hydrolysed in basic media to the potassium salt of dinitromethane. Alloxane was prepared in a one step procedure by thermal decomposition of 5,5-dinitrobarbituric acid in hot acetic acid.

The impaired fibrinolytic capacity in hypertension is unaffected by acute blood pressure lowering

Tidskriftsartikel (refereegranskat)abstract
- The endogenous fibrinolytic system and the ability of the endothelium to release tissue-plasminogen activator (t-PA) play a pivotal role to protect humans from atherothrombotic events. We have recently reported that the decreased capacity for t-PA release in hypertension is restored with chronic blood pressure lowering. Thus, we explored if acute blood pressure lowering has the same effect. The capacity for acute t-PA release was investigated in the perfused-forearm model during stimulation by intra-arterial substance P 8 pmol/min in hypertensive subjects. The procedure was then repeated during acute blood pressure lowering (n = 9) induced by sodium nitroprusside (SNP) infusion or during placebo infusion (n = 3). SNP lowered mean arterial pressure from 108.6 (2.6) to 83.0 (2.6) (mean and SEM) mmHg (P < 0.001). Substance P induced significant increase in t-PA release during both high- and low-pressure conditions (P < 0.01, ANOVA). Peak t-PA release rate was 199 (77) and 167 (41) (mean and SEM) ng/min/l tissue, and accumulated t-PA release was 2,395 (750) and 2,394 (473) ng, during high- and low-pressure conditions, respectively. t-PA release and hemodynamic responses were almost identical during high- and low-pressure conditions (P = ns, for all). Acute blood pressure lowering does not restore stimulated t-PA release from the endothelium in hypertensive subjects. These findings are in contrast to previously described effects of chronic blood pressure treatment. Although data need to be confirmed in a larger study, they suggest that high blood pressure decreases the cellular t-PA pool rather than interferes with release mechanisms of the protein.
