Summary
Biomedical abstracts contain less information than full-text articles. Citances (sentences with citations) capture more concepts than abstracts, revealing differences in author versus peer perspectives on key findings.
Area of Science:
- Biomedical informatics
- Scientific communication
- Molecular biology
Background:
- Increasing accessibility of full-text biomedical publications enables new text analysis methods.
- The information content of abstracts versus full-text articles requires investigation.
- Understanding author versus peer perspectives on research is crucial.
Purpose of the Study:
- To compare the information content of abstracts with citances (sentences containing citations).
- To identify information present in full-text but absent in abstracts.
- To contrast author-judged importance with peer-perceived significance of article content.
Main Methods:
- Manual and automatic text analysis of biomedical publications.
- Comparison of information entities, functions, experimental methods, and biological concepts.
- Analysis focused on the area of molecular interactions.
Main Results:
- Citances cover most information found in abstracts and contain 20% more concepts.
- Significant differences exist in information types between abstracts and citances.
- The study details how other citations and time influence citance content.
Conclusions:
- Biomedical abstracts may not fully represent the information in full-text articles.
- Citances offer a richer source of information compared to abstracts.
- Peer perception of article content, as reflected in citances, differs from author emphasis.

01:33Pleiotropy
Pleiotropy is the phenomenon in which a single gene impacts multiple, seemingly unrelated phenotypic traits. For example, defects in the SOX10 gene cause Waardenburg Syndrome Type 4, or WS4, which can cause defects in pigmentation, hearing impairments, and an absence of intestinal contractions necessary for elimination. This diversity of phenotypes results from the expression pattern of SOX10 in early embryonic and fetal development. SOX10 is found in neural crest cells that form melanocytes,...

Overview
01:10Nature and Nurture
Many human characteristics, like height, are shaped by both nature—in other words, by our genes—and by nurture, or our environment. For example, chronic stress during childhood inhibits the production of growth hormones and consequently reduces bone growth and height. Scientists estimate that 70-90% of variation in height is due to genetic differences among individuals, and 10-30% of variation in height is due to differences in the environments that individuals experience, such as differences...
01:23Influence of Parents and Peers on Identity
Adolescence is a pivotal period of identity formation, during which individuals begin to answer questions central to their sense of self, such as "Who am I?" and "Who do I hope to become?" Both parents and peers play critical roles in guiding adolescents through this complex developmental phase.
Parental Influence on Identity Development
Parents serve as primary guides and managers in an adolescent's life, offering support instrumental in decision-making and personal growth. This guiding role...

01:03Altruism
Altruistic behaviors are “unselfish” behaviors—those that help another individual at the expense of the individual carrying out the behavior. Despite the negative consequences for the altruistic animal, these behaviors are thought to have evolved for several reasons.
03:00Self-Evaluation: Self-Enhancement and Self-Verification
Social psychologists have documented that feeling good about ourselves and maintaining positive self-esteem is a powerful motivator of human behavior (Tavris & Aronson, 2008). In the United States, members of the predominant culture typically think very highly of themselves and view themselves as good people who are above average on many desirable traits (Ehrlinger, Gilovich, & Ross, 2005). Often, our behavior, attitudes, and beliefs are affected when we experience a threat to our...
