Fish drug analysis—Phish-pharm: A searchable database of pharmacokinetics data in fish

Information about drug residues and pharmacokinetic parameters in aquatic species is relatively sparse. In addition, it is difficult to rapidly compare data between studies due to differences in experimental conditions, such as water temperatures and salinity. To facilitate the study of aquatic species drug metabolism, we constructed a Fish Drug/Chemical Analysis Phish-Pharm (FDA-PP) database. This database consists of more than 400 articles that include data from 90 species (64 genera) of fish. Data fields include genus, species, water temperatures, the average animal weight, sample types analyzed, drug (or chemical) name, dosage, route of administration, metabolites identified, method of analysis, protein binding, clearance, volume of distribution in a central compartment (Vc) or volume of distribution at steady-state (Vd), and drug half-lives (t((1/2))). Additional fields list the citation, authors, title, and Internet links. The document will be periodically updated, and users are invited to submit additional data. Updates will be announced in future issues of The AAPS Journal. This database will be a valuable resource to investigators of drug metabolism in aquatic species as well as government and private organizations involved in the drug approval process for aquatic species.

Analysis of medical students' use of web-based resources for a gross anatomy and embryology course

An extensive Web site supporting our gross anatomy and embryology course, which includes various course management pages as well as online lectures, has been in use for the past 2 years. To determine how this Web site is being used by students, we examined server log files to track access to each of the Web pages on the site. Using this data, along with student responses on a course evaluation, we have been able to quantitatively characterize Web site use and gain some insight into students' perception of the site. This analysis showed that all of the resources available online, including course management information, exam reviews, online lectures, and dissection guides were heavily used and deemed useful by students. Despite universal computer ownership and Internet access from home, most use of the Web site was from on-campus computer labs, especially for lectures with audio streams. This was probably due to the limited bandwidth of off-campus connections. Data on the day of the week and time of the day of access showed peak activity at expected times, but also significant activity at all hours, as students took full advantage of 'access on demand.' This on-demand nature of the Web was also evident in students' viewing of lectures in short sessions rather than in one sitting. Online lectures were used regularly by a majority of students both before and after corresponding class sessions, however, this was not the preferred venue for all students. Although the flexibility of Web-based resources accommodates students' varying study habits, the alternative of traditional print material and live lectures should not be abandoned lightly.     

Performance of Web-based image distribution: client-oriented measurements

The aim of this study was to define a clinically suitable personal computer (PC) configuration for Web-based image distribution and to assess the influence of different hard- and software configurations on the performance. Through specially developed software the time-to-display (TTD) for various PC configurations was measured. Different processor speeds, random access memory (RAM), screen resolutions, graphic adapters, network speeds, operating systems and examination types (computed radiography, CT, MRI) were evaluated, providing more than half a million measurements. Processor speed was the most relevant factor for the TTD; doubling the speed halved the TTD. Under processor speeds of 350 MHz, TTD mostly remained above 5 s for 1 CR or 16 CT images. Here Windows NT with lossy compression were superior. Processor speeds of 350 MHz and over delivered TTD <5 s. In this case Windows 2000 and lossless compression were preferable. Screen resolutions above 1280×1024 pixels increased the TTD mainly for CR images. The RAM amount, network speed and graphic adapter did not have a significant influence. The minimum threshold for clinical routine is any standard off-the-shelf PC better than Pentium II 350 MHz, 128 MB RAM; hence, high-end PC hardware is not required.
