Online presentations as a source of scientific impact? An analysis of PowerPoint files citing academic journals
Authors: Thelwall Mike , Kousha Kayvan 
Published: January 2008

AbstractOpen‐access online publication has made available an increasingly wide range of document types for scientometric analysis. In this article, we focus on citations in online presentations, seeking evidence of their value as nontraditional indicators of research impact. For this purpose, we searched for online PowerPoint files mentioning any one of 1,807 ISI‐indexed journals in ten science and ten social science disciplines. We also manually classified 1,378 online PowerPoint citations to journals in eight additional science and social science disciplines. The results showed that very few journals were cited frequently enough in online PowerPoint files to make impact assessment worthwhile, with the main exceptions being popular magazines likeScientific AmericanandHarvard Business Review. Surprisingly, however, there was little difference overall in the number of PowerPoint citations to science and to the social sciences, and also in the proportion representing traditional impact (about 60%) and wider impact (about 15%). It seems that the main scientometric value for online presentations may be in tracking the popularization of research, or for comparing the impact of whole journals rather than individual articles.
Are there better indices for evaluation purposes than the h index? A comparison of nine different variants of the h index using data from biomedicine
Authors: Bornmann Lutz , Mutz Rüdiger , Daniel Hans‐Dieter 
Published: February 2008

AbstractIn this study, we examined empirical results on the h index and its most important variants in order to determine whether the variants developed are associated with an incremental contribution for evaluation purposes. The results of a factor analysis using bibliographic data on postdoctoral researchers in biomedicine indicate that regarding the h index and its variants, we are dealing with two types of indices that load on one factor each. One type describes the most productive core of a scientist's output and gives the number of papers in that core. The other type of indices describes the impact of the papers in the core. Because an index for evaluative purposes is a useful yardstick for comparison among scientists if the index corresponds strongly with peer assessments, we calculated a logistic regression analysis with the two factors resulting from the factor analysis as independent variables and peer assessment of the postdoctoral researchers as the dependent variable. The results of the regression analysis show that peer assessments can be predicted better using the factor ‘impact of the productive core’ than using the factor ‘quantity of the productive core.’

Published: January 2008

AbstractAntofloxacin hydrochloride is a newly developed fluoroquinolone antibacterial in China, which has comparable in vitro and animal pharmacological and toxicological properties to levofloxacin and is worthy of further clinical trial. Human tolerance of single escalating doses from 50 to 500 mg was shown to be safe. The purpose of the present study was to evaluate the pharmacokinetic characteristics of a single oral dose of antofloxacin hydrochloride in Chinese healthy male volunteers. Twelve subjects were randomized for administration of a single dose of 300, 400 and 500 mg antofloxacin hydrochloride in a 3‐way crossover design. High pressure liquid chromatography (HPLC) was used to assay the serum and urine concentrations of antofloxacin in samples collected over a period of 72 h following drug administration. All three dosages were well tolerated. Antofloxacin hydrochloride demonstrated linear pharmacokinetic characteristics with mean pharmacokinetic values varying from 0.09 to 0.10 l/h/kg for CL/F and from 2.75–3.00 l/kg for V/F. The t1/2β was around 20 h and the mean fraction of dose excreted in urine varied from 0.40 to 0.46. Based on these data, 300 mg of antofloxacin hydrochloride administered once daily was selected for further investigation in a multiple dose administration study.

Fetal alcohol syndrome (FAS) in C57BL/6 mice detected through proteomics screening of the amniotic fluid
Authors: Datta Susmita , Turner Delano , Singh Reetu , Ruest L. Bruno , Pierce William M. , Knudsen Thomas B. 
Published: January 2008

AbstractBACKGROUND:Fetal Alcohol Syndrome (FAS), a severe consequence of the Fetal Alcohol Spectrum Disorders, is associated with craniofacial defects, mental retardation, and stunted growth. Previous studies in C57BL/6J and C57BL/6N mice provide evidence that alcohol‐induced pathogenesis follows early changes in gene expression within specific molecular pathways in the embryonic headfold. Whereas the former (B6J) pregnancies carry a high‐risk for dysmorphogenesis following maternal exposure to 2.9 g/kg alcohol (two injections spaced 4.0 h apart on gestation day 8), the latter (B6N) pregnancies carry a low‐risk for malformations. The present study used this murine model to screen amniotic fluid for biomarkers that could potentially discriminate between FAS‐positive and FAS‐negative pregnancies.METHODS:B6J and B6N litters were treated with alcohol (exposed) or saline (control) on day 8 of gestation. Amniotic fluid aspirated on day 17 (n = 6 replicate litters per group) was subjected to trypsin digestion for analysis by matrix‐assisted laser desorption–time of flight mass spectrometry with the aid of denoising algorithms, statistical testing, and classification methods.RESULTS:We identified several peaks in the proteomics screen that were reduced consistently and specifically in exposed B6J litters. Preliminary characterization by liquid chromatography tandem mass spectrometry and multidimensional protein identification mapped the reduced peaks to alpha fetoprotein (AFP). The predictive strength of AFP deficiency as a biomarker for FAS‐positive litters was confirmed by area under the receiver operating characteristic curve.CONCLUSIONS:These findings in genetically susceptible mice support clinical observations in maternal serum that implicate a decrease in AFP levels following prenatal alcohol damage.

No effect of mobile phone‐like RF exposure on patients with atopic dermatitis

Published: January 2008

AbstractThis study investigates the effect of exposure to a mobile phone‐like radiofrequency (RF) electromagnetic field on people with atopic dermatitis (AD). Fifteen subjects with AD were recruited and matched with 15 controls without AD. The subjects were exposed for 30 min to an RF field at 1 W/kg via an indoor base station antenna attached to a 900 MHz GSM mobile phone. Blood samples for ELISA analysis of the concentration of substance P (SP), tumor necrosis factor receptor 1 (TNF R1), and brain derived neurotrophic factor (BDNF) in serum were drawn before and after the provocation (exposure/sham). Baseline heart rate and heart rate variability, local blood flow, and electrodermal activity were also recorded. No significant differences between the subject groups were found for baseline neurophysiological data. The cases displayed a serum concentration of TNF R1 significantly higher than the control subjects and a significantly lower serum concentration of BDNF in the baseline condition. For SP there was no difference between groups. However, no effects related to RF exposure condition were encountered for any of the measured substances. As to symptoms, a possible correlation with exposure could not be evaluated, due to too few symptom reports. The result of the study does not support the hypothesis of an effect of mobile phone‐like RF exposure on serum levels of SP, TNF R1, and BDNF in persons with AD.

New Redesigned Zinc‐Finger Proteins: Design Strategy and Its Application
Authors: Negi Shigeru , Imanishi Miki , Matsumoto Makoto , Sugiura Yukio 
Published: January 2008

AbstractThe design of DNA‐binding proteins for the specific control of the gene expression is one of the big challenges for several research laboratories in the post‐genomic era. An artificial transcription factor with the desired DNA binding specificity could work as a powerful tool and drug to regulate the target gene. The zinc‐finger proteins, which typically contain many fingers linked in a tandem fashion, are some of the most intensively studied DNA‐binding proteins. In particular, the Cys2His2‐type zinc finger is one of the most common DNA‐binding motifs in eukaryotes. A simple mode of DNA recognition by the Cys2His2‐type zinc‐finger domain provides an ideal framework for designing proteins with new functions. Our laboratory has utilized several design strategies to create new zinc‐finger peptides/proteins by redesigning the Cys2His2‐type zinc‐finger motif. This review focuses on the aspects of design strategies, mainly from our recent results, for the creation of artificial zinc‐finger proteins, and discusses the possible application of zinc‐finger technology for gene regulation and gene therapy.
Total Synthesis of (+)‐Alexine by Utilizing a Highly Stereoselective [3+2] Annulation Reaction of an N‐Tosyl‐α‐Amino Aldehyde and a 1,3‐Bis(silyl)propene
Authors: Dressel Martina , Restorp Per , Somfai Peter 
Published: January 2008

AbstractA novel route towards the polyhydroxylated pyrrolizidine alkaloid (+)‐alexine has been developed. A key step in this synthesis is a highly stereoselective [3+2] annulation reaction of N‐Ts‐α‐amino aldehyde 7 a (Ts=tosyl) and 1,3‐bis(silyl)propene 8 a for the construction of the polyhydroxylated pyrrolidine subunit of the target molecule. Previous synthetic strategies rely on carbohydrates that require several protecting‐group manipulations, thereby making the total number of steps relatively high. The [3+2] annulation strategy compares favorably with carbohydrate‐based syntheses and constitutes a highly efficient entry to polyhydroxylated alkaloids.
