A Mycobacterium strain (RP1) was isolated from a contaminated activated sludge collected in a wastewater treatment unit of a chemical plant. It was capable of utilizing morpholine and other heterocyclic compounds, such as pyrrolidine and piperidine, as the sole source of carbon, nitrogen, and energy. The use of in situ1H nuclear magnetic resonance (1H NMR) spectroscopy allowed the determination of two intermediates in the biodegradative pathway, 2-(2-aminoethoxy)acetate and glycolate. The inhibitory effects of metyrapone on the degradative abilities of strain RP1 indicated the involvement of a cytochrome P-450 in the biodegradation of morpholine. This observation was confirmed by spectrophotometric analysis and1H NMR. Reduced cell extracts from morpholine-grown cultures, but not succinate-grown cultures, gave rise to a carbon monoxide difference spectrum with a peak near 450 nm, which indicated the presence of a soluble cytochrome P-450. 1H NMR allowed the direct analysis of the incubation medium containing metyrapone, a specific inhibitor of cytochrome P-450. The inhibition of morpholine degradation was dependent on the morpholine/metyrapone ratio. The heme-containing monooxygenase was also detected in pyrrolidine- and piperidine-grown cultures. The abilities of different compounds to support strain growth or the induction of a soluble cytochrome P-450 were assayed. The results suggest that this enzyme catalyzes the cleavage of the C—N bond of the morpholine ring.

Ein 81-jähriger Läufer mit Status nach aortokoronarem Bypass bei bekannter koronarer Herzkrankheit hat einen 100-km-Lauf in 19 h und 45 min erfolgreich beendet. Vor und unmittelbar nach dem Lauf wurden Fett- und Muskelmasse nicht-invasiv sowohl mit der bioelektrischen Impedanzanalyse als auch mit der klassischen Hautfaltenmethode bestimmt. Zusätzlich wurden Blut- und Urinproben zur Beurteilung des Flüssigkeitshaushaltes genommen und eine ¹H-NMR-Spektroskopie des Urins zum Nachweis eines erhöhten Kohlenhydrat-, Fett- oder Eiweissstoffwechsels durchgeführt. Das Körpergewicht nahm um 1.9 kg ab. Während die errechnete Muskelmasse um 0.1 kg zunahm, nahm die errechnete Fettmasse um 0.2 kg (anthropometrische Methode) resp. 3.1 kg (BIA) ab. Das errechnete Körperwasser nahm um 1.2 l zu. Während Hämatokrit, Harnstoff und spezifisches Gewicht des Urins zunahmen, sank das Natrium im Blut ab. Das Plasmavolumen nahm um 19% ab. Die ¹H-NMR-Spektroskopie des Urins zeigte nach der Belastung einen Anstieg der Ketonkörper. Um einen Abbau der Muskelmasse objektivieren zu können, muss der Ausgangswert des Körperwassers abgewartet werden, um keine Fehlinterpretation aufgrund der Methoden zu machen. Unklar bleibt, wieso es zu einer Einlagerung von Wasser kam. In weiteren Untersuchungen könnten zusätzliche Methoden wie DEXA, Muskelbiopsien und Bestimmung von weiteren Blut- und Urinparametern Auskunft geben, ob effektiv und wie viel Muskelmasse abgebaut wird und ob Abbauprodukte der Muskulatur die Nierenfunktion einschränken und somit zu einer Wasserretention führen.

Traditional medicine in Indonesia has been known by the public before formal health services using modern medicine. Indonesia has many type of herbal plants which have medicinal properties including dadap (Erythrina orientalis). This study aims to utilized dadap herbal liniment by modifying heating in Vigin Cocanut Oil. The study conducted in the laboratory of Agricultural Product Processing using a Factorial Completely Randomized Design (CRD). The first factor is the addition of 250 ml (M1), 375 ml (m2), and 400 ml (M3) Virgin Cocanut Oil treatment. The second factor is the heating tim of 5 minutes (L1), 10 minutes (L2), and 15 minutes (L3). Observation variable consisted of yield, Specific gravity, and organoleptic test of aroma and colored. The result showed an average yield of 87.70-91.88%. The highest yield was found in the treatment of adding 400 ml Virgin Cocanut Oil and 15 minutes of heating time. The highest type of weight was found in the treatment of addition of 325 ml Virgin Cocanut Oil and 5 minutes heating time. Based on the organoleptic scent test, the everage penalist gives a like answer. Organoleptic colors of reudeuep herbal products is according to SNI number 06-23-2006.

Abstract: More than 90% of herbal products and herbal medicines have been derived from higher plants recently, but due to independent circumstances, several photosynthetic microalgal species are in focus in this point of view. In the last 50 years, many carbohydrate-, peptide-, terpenoid-, alkaloid- and phenol-type components were described from algae because of the developing structural determination and analytical methods, algae mass production and also artificial algae technologies. At the same time, based partly on traditional causes and partly on the clinical and preclinical data of today, some dried products of algae are directly used as food supplements. Hereinafter, the historical background, economic significance and metabolic background of the mostly used microalgal species will be reviewed. The diverse metabolite production of these organisms will be demonstrated by some molecules with special bioactivity. Several preclinical and clinical studies will be described relating to the microalgal species Spirulina sp., Chlorella sp., Haematococcus sp. and Dunaliella sp. Orv Hetil. 2018; 159(18): 703–708.
