Summary
Frailty research has evolved over 40 years, shifting from impact to determinants and measurement. Recent trends highlight dementia and frailty prevention through nutrition and activities of daily living.
Area of Science:
- Gerontology and Public Health
- Bibliometrics and Scientometrics
- Social Network Analysis
Background:
- This study analyzes the evolution of frailty research over four decades using bibliometric and social network analysis techniques.
- Keywords from 6,424 articles published between 1981 and April 2016 were analyzed to map research trends and networking features.
Observation:
- Frailty research keywords have shifted from 'impact' in the 1980s to 'malnutrition' and 'chronic disease' in the 1990s and 2000s.
- In the 2010s, research focus expanded to include 'dementia,' 'malnutrition,' and 'measurement' of frailty.
- Early research emphasized individual behavior modification, while later research integrated disease-specific aspects like sarcopenia and disability.
Findings:
- 'Dementia' emerged as a highly central keyword in the 2010s, indicating a strong focus on cognitive function in frailty studies.
- The network analysis revealed a shift towards understanding frailty as a multifactorial condition, incorporating elements of disease and aging.
- Key themes in the 2010s included obesity, nutrition, prevention, evaluation, and activities of daily living (ADL) in frailty research.
Implications:
- This systematic overview of frailty knowledge development provides insights into research trajectories and emerging areas of focus.
- The findings underscore the increasing complexity of frailty research, integrating biological, social, and functional aspects.
- Understanding these trends can inform future research agendas and public health strategies for addressing frailty.

01:23Journal Bearings
1.2K
Journal bearings are mechanical components that support and provide lateral stability to rotating shafts and axles. They are crucial in reducing friction, wear, and vibration in machinery such as engines, turbines, and pumps. The principle behind journal bearings is forming a thin lubricant film between the bearing surface and the rotating shaft, which minimizes direct contact and reduces frictional forces.

02:26Protein Networks
4.6K
An organism can have thousands of different proteins, and these proteins must cooperate to ensure the health of an organism. Proteins bind to other proteins and form complexes to carry out their functions. Many proteins interact with multiple other proteins creating a complex network of protein interactions.
These interactions can be represented through maps depicting protein-protein interaction networks, represented as nodes and edges. Nodes are circles that are representative of a protein,...

Network covalent solids contain a three-dimensional network of covalently bonded atoms as found in the crystal structures of nonmetals like diamond, graphite, silicon, and some covalent compounds, such as silicon dioxide (sand) and silicon carbide (carborundum, the abrasive on sandpaper). Many minerals have networks of covalent bonds.
To break or to melt a covalent network solid, covalent bonds must be broken. Because covalent bonds are relatively strong, covalent network solids are typically...

01:42Microtubule Associated Proteins (MAPs)
6.0K
Microtubule function and architecture are regulated by an array of specialized proteins called microtubule-associated proteins or MAPs. These proteins are widespread across different organisms and have conserved protein motifs, like the multi-TOG domain for tubulin binding found in the CLASP family of MAPs. Some MAPs are lineage-specific based on their conserved domains. Their functions depend upon the cytoskeletal architecture and cell type they are located within. In-plant cells, a specific...

02:22Structures of Solids
18.2K
Solids in which the atoms, ions, or molecules are arranged in a definite repeating pattern are known as crystalline solids. Metals and ionic compounds typically form ordered, crystalline solids. A crystalline solid has a precise melting temperature because each atom or molecule of the same type is held in place with the same forces or energy. Amorphous solids or non-crystalline solids (or, sometimes, glasses) which lack an ordered internal structure and are randomly arranged. Substances that...
