Dermatoscopy image characteristics and differences among commonly used standard dermatoscopes

Investigating Differences among the Commonly Used Video Lecture Styles

Many educational organizations are motivated to create and share instructional videos, but there are no guidelines about the presentation styles. In practice, the presentation style of video lectures ranges from simple video capturing of classroom teaching, up to highly elaborate authoring of video presentations that include close-ups and video-cuts of instructors, slides, animations, and inter...

Mechanical characteristics of three staples commonly used in foot surgery

BACKGROUND Bone staples are an accepted method of fixation in foot surgery. They reduce operating time and trauma in surgical procedures. A variety of memory staples are available but their properties compared to standard staples are not known. We carried out a study comparing two popular types of memory staples and a standard stainless steel staple. METHODS Standardized bone models of metata...

Location- and sex-specific differences in weight and motor coordination in two commonly used mouse strains

Several studies have shown that environmental factors can affect the outcome of behavioral experiments, shedding doubts on the inter-laboratory reproducibility of behavioral test results. When our laboratory moved from the University of Rochester, Rochester, NY, to Sanford Research in Sioux Falls, SD, our mouse colony was also transferred and the new environment caused strain-dependent changes ...

Electrophilicity and nucleophilicity of commonly used aldehydes.

The present approach for determining the electrophilicity (E) and nucleophilicity (N) of aldehydes includes a kinetic study of KMNO4 oxidation and NaBH4 reduction of aldehydes. A transition state analysis of the KMNO4 promoted aldehyde oxidation reaction has been performed, which shows a very good correlation with experimental results. The validity of the experimental method has been tested usi...
