    Notes:
    Volatile compounds in the aroma of five varieties of roasted and unroasted (raw) cocoa beans have been identified by mass spectral analysis and gas chromatography. The five common varieties selected for this study all contain the following compounds usually in this order of abundance: isovaleraldehyde, isobutyraldehyde, propionaldehyde, methyl alcohol, acetaldehyde, methyl acetate, n-butyraldehyde, and diacetyl. An additional eight compounds appear in smaller amounts. As evidenced by gas chromatographic analysis, the raw bean aroma contains the same components but in lower concentrations. The principal differences between varieties are shown to be due to the ratios of these compounds rather than new compounds. The effect of roasting period on the concentration of four aldehydes in the aroma of the ground bean is shown.

    [Auszug] The concept of an electrical current encircling the Earth at high altitudes was first proposed in 1917 to explain the depression of the horizontal component of the Earth’s magnetic field during geomagnetic storms. In situ measurements of the extent and composition of this current were ...

    [Auszug] Strong discrete aurorae on Earth are excited by electrons, which are accelerated along magnetic field lines towards the planet. Surprisingly, electrons accelerated in the opposite direction have been recently observed. The mechanisms and significance of this anti-earthward acceleration are ...

    [Auszug] The space environments—or magnetospheres—of magnetized planets emit copious quantities of energetic neutral atoms (ENAs) at energies between tens of electron volts to hundreds of kiloelectron volts (keV). These energetic atoms result from charge exchange between magnetically trapped ...

    [Auszug] The interaction of the solar wind with Earth's magnetosphere gives rise to the bright polar aurorae and to geomagnetic storms, but the relation between the solar wind and the dynamics of the outer planets' magnetospheres is poorly understood. Jupiter's magnetospheric dynamics ...

    Abstract Different imaging appearances of giant hyperplastic change of the caudate lobe of the liver are presented in a patient with liver cirrhosis. The mass like caudate lobe was isoechoic on ultrasound, hypodense on postcontrast computed tomography (CT), hyperintense on T1-weighted magnetic resonance, images and isointense on T2-weighted images. These imaging findings are similar to those of dysplastic nodule in cirrhotic liver. The caudate lobe received normal portal flow on CT during arterial portography, but superior mesenteric arteriography showed precocious or early division of the caudate portal branch. We suspect that caudate hyperplastic change may be correlated to anomalous caudate portal vein branch.

    Notes:
    Abstract Dynamic contrast-enhanced whole-abdomen axial images were obtained by using a fat-suppressed, three-dimensional, breath-hold enhanced fast spoiled gradient-echo technique, configured for optimal evaluation for detection and characterization of liver lesions. We then evaluated the feasibility of using these images to reconstruct “free” abdominal magnetic resonance angiography, without additional cost or acquisition time, in 32 randomly chosen patients. The aorta, celiac trunk, superior mesenteric, hepatic, splenic, and renal arteries were clearly depicted.

    Notes:
    Abstract We describe two cases of Budd-Chiari syndrome detected by magnetic resonance imaging that resulted from compression of the inferior vena cava by an elevated right hemidiaphragm. Magnetic resonance images demonstrated elevation of the right hemidiaphragm and medial deviation of the inferior vena cava with short segmental narrowing. The hepatic veins and inferior vena cava were patent but discontinuous. Hepatic venous drainage was assisted by multiple large intrahepatic collaterals.

    Abstract Background: To describe the characteristic magnetic resonance imaging (MRI) findings of gallbladder adenomyomatosis in two cases. Methods: Two patients had abdominal MRI findings of gallbladder adenomyomatosis confirmed at cholecystectomy. Results: The surgical specimen showed findings typical of adenomyomatosis, including marked thickening of both epithelial and muscular elements with multiple Rokitansky-Aschoff sinuses. On gadolinium-enhanced spoiled gradient-echo images and single-shot fast spin-echo images, mild gallbladder wall thickening with multiple intramural cystic components from Rokitansky-Aschoff sinuses were readily visualized. Conclusion: Adenomyomatosis of the gallbladder can be detected and diagnosed from MRI findings.

    Notes:
    Abstract. A “quadraphasic” imaging technique is described for imaging malignancies of the abdomen (liver, kidneys and pancreas). With this technique images are aquired during four different phases relative to the administration of contrast agent: pre-contrast (baseline), during the capillary (arterial, pre-sinusoidal) phase, during the portal (sinusoidal) phase, and during the extracellular (delayed) phase. A brief summary of the kinds of malignancy that are best imaged during each of these phases is presented. Finally, comments are presented on the use of gadolinium-based contrast media for imaging tissues of the pelvis.
