This study evaluates the effectiveness of human anatomy software in face-to-face and online anatomy laboratory classes. Cognitive, affective, and psychomotor perceived learning was measured for students using Pearson Education's Practice Anatomy Laboratory 2.0 software. This study determined that student-perceived learning was significantly greater in the online class environment and was specifically related to psychomotor learning. The findings of this study have implications for future educational practice in the use of advanced digital software for learning in both traditional and online education courses as instructors seek to find better methods to assist their students in developing skills in learning human anatomy.

In the last 25 to 30 years, since the inception of personal computers, analysis of digital images has become a commonplace task in both the biological and industrial laboratory. Concurrent […]

Descriptive biochemical characteristics of aqueous extracts from young adult and aged male and female rat sublingual glands, have been examined. No change in gland protein or DNA content was observed with increased age. The concentrations of sialic acids and neutral sugars, in gland extracts, from aged rats of both sexes, were increased 25-50% compared to their young adult counterparts. No consistent difference in any individual protein species, resolved by 3.75% and 10% acrylamide gel/SDS electrophoresis, was found. [ABSTRACT FROM AUTHOR]

Submandibular glands from young adult and aged male and female rats have been examined and various descriptive parameters obtained. Several sex differences were observed with tissue from young and old animals. Sex differences were found in the gland contents of DNA, protein, and sialic acid and in some protein components resolved by gel electrophoresis. Significant age-related decreases in the gland contents of protein, sialic acid, and neutral sugar, but not DNA, were found with male rats. In female rats these values were constant across the animal's adult lifespan. [ABSTRACT FROM AUTHOR]
