Screening of tropical medicinal plants for antiinflammatory activity
1995
The antiinflammatory activity of different extracts from 16 tropical plant species belonging to 15 different families has been determined. They were administered topically on TPA-induced mouse ear oedema and orally on carrageenan-induced mouse paw oedema. In the latter, extracts from Diospyros leucomelas, Erythrospermum monticolumn, Ficus polita, Heteromorpha trifoliata, Hypericum lalandii, Kirkia acuminata, Pterocarpus angolensis and Zanha africana significantly reduced the oedema 3 h after carrageenan injection. All the extracts were considerably active when assayed topically with only three exceptions.
Moulting hormone content in prothoracic glands and oenocytes ofTenebrio molitor within a moulting cycle
1973
An isolierten und homogenisierten Prothorakaldrusen und Oenocyten vonTenebrio wurde der Gehalt an Hautungshormonen mit Hilfe des Calliphoratests bestimmt. Dabei stellte sich heraus, dass sowohl Prothorakaldrusen als auch Oenocyten wahrend des gesamten Hautungszyklus verpuppungsaktive Stoffe, wenn auch in unterschiedlicher Menge, enthalten. Die Ergebnisse werden mit jenen verglichen, bei denen der Hormontiter durch Extraktion ganzer Tiere bestimmt wurde. In Verbindung damit wurde das Zusammenspiel von Synthese und Abbau der Hormone diskutiert.
COOL, LCG Conditions Database for the LHC Experiments: Development and Deployment Status
2008
The Large Hadron Collider (LHC), the world’s largest and highest-energy particle accelerator, designed to collide opposing beams of protons or lead ions, started its operations in September 2008 at the European Organization for Nuclear Research (CERN) in Geneva, Switzerland. To process and analyze the huge amounts of data generated by the four experiments installed at different collision points along the LHC ring, a large distributed computing infrastructure has been set up, the LHC Computing Grid (LCG). The bulk of this data, referred to as ‘event data’, will record the signals left in the sub-detectors of the four LHC experiments by the passage of the particles generated in the collision …
Quantum Search with Multiple Walk Steps per Oracle Query
2015
We identify a key difference between quantum search by discrete- and continuous-time quantum walks: a discrete-time walk typically performs one walk step per oracle query, whereas a continuous-time walk can effectively perform multiple walk steps per query while only counting query time. As a result, we show that continuous-time quantum walks can outperform their discrete-time counterparts, even though both achieve quadratic speedups over their corresponding classical random walks. To provide greater equity, we allow the discrete-time quantum walk to also take multiple walk steps per oracle query while only counting queries. Then it matches the continuous-time algorithm's runtime, but such …

Triterpenoid saponins from the cultivar “Green Elf” of Pittosporum tenuifolium
2021
Four oleanane-type glycosides were isolated from a horticultural cultivar “Green Elf” of the endemic Pittosporum tenuifolium (Pittosporaceae) from New Zealand: three acylated barringtogenol C glycosides from the leaves, with two previously undescribed 3-O-β-d-glucopyranosyl-(1→2)-[α-l-arabinopyranosyl-(1→3)]-β-d-glucuronopyranosyl-21-O-angeloyl-28-O-acetylbarringtogenol C, 3-O-β-d-galactopyranosyl-(1→2)-[α-l-arabinopyranosyl-(1→3)]-β-d-glucuronopyranosyl-21-O-angeloyl-28-O-acetylbarringtogenol C, and the known 3-O-β-d-glucopyranosyl-(1→2)-[α-l-arabinopyranosyl-(1→3)]-β-d-glucuronopyranosyl-21-O-angeloyl-28-O-acetylbarringtogenol C (Eryngioside L). From the roots, the known 3-O-β-d-glucopyra…
Effects of the prolonged thoracic epidural analgesia on ventilation function and complication rate after the lung cancer surgery.
2006
Thoracic epidural analgesia has been considered to have a good anesthetic efficacy and to decrease the postoperative complication rate, while its effect upon the ventilation function is still the topic of many clinical studies. The aim of this study was to evaluate the course of early postoperative period using thoracic epidural analgesia. Material and methods. A total of 453 patients undergoing the operation due to the non–small cell carcinoma were selected and examined. Their postoperative complications and mortality rate were evaluated. In 79 patients, arterial oxygen saturation (SaO2), forced vital capacity, forced expiratory volume in the first second, and the efficacy of analgesia wer…
