The topical anti-inflammatory activity of extracts from Cassia angustifolia, Rheum palmatum, Coptis chinensis, Phellodendron amurense and Scutellaria baicalensis, plants used in traditional East Asian medicine against different skin disorders, was studied. Though in different degree, all the extracts significantly inhibited the edema induced by(More)
The concept of system use has suffered from a "too simplistic definition" (DeLone and McLean [9], p. 16). This paper reviews various attempts at conceptualization and measurement of system use and then proposes a re-conceptualization of it as "the level of incorporation of an information system within a user's processes." We then go on to develop the(More)
This paper explores the applicability of the concepts of absorptive capacity and ‘‘ba’’ to ex ante project risk. We develop a hybrid framework to explain knowledge transfer based on these concepts—one that proposes a hybrid transference process. We then apply this framework to develop a methodology and metric for assessing ex ante software project risk, the(More)
The hydroalcoholic extract from P. cocos was examined for oral and topical anti-inflammatory activities. It proved to be active against carrageenan, arachidonic acid, tetradecanoyl phorbol acetate (TPA) acute edemas, TPA chronic inflammation and oxazolone delayed hypersensitivity in mice. Two lanostane-type triterpenes were isolated and identified by(More)

Following previous research findings, this paper argues that the current method of evaluating scholar performance, publication counts in “quality” journals is flawed by subjectivity in generating the list of approved journals and the definition of quality. Truex, Cuellar and Takeda (2009) sought to improve on this method by substituting the measurement of(More)
Three new saponins, zanhasaponins, A, B, and C, were isolated from the MeOH extract of the root bark of Zanha africana and were, respectively, identified by spectroscopic methods as 3-O-beta-D-glucuronopyranosyl-2 beta,16 alpha-dihydroxyolean-12-ene-23,28- dioic acid 28-O-alpha-L-rhamnopyranosyl(1-->2)-alpha-L-rhamnopyranoside (1);(More)
A MeOH extract from Z. africana was examined for topical antiinflammatory activity and proved to be active against arachidonic acid (AA) acute edema, 12-O-tetradecanoylphorbol 13-acetate (TPA)-induced chronic inflammation, and oxazolone delayed-type hypersensitivity in mice. The extract also showed significant inhibitory activity of Naja naja phospholipase(More)
