Summary
Preclinical frailty models, including mouse, rat, and canine, are crucial for understanding aging and developing treatments. These models help investigate frailty mechanisms and test interventions to improve health span.
Area of Science:
- Geriatric Research
- Aging Biology
- Preclinical Models
Background:
- Frailty, a state of increased vulnerability, impacts health span and lifespan.
- Understanding frailty mechanisms is critical, yet remains unclear.
- Preclinical models are essential for advancing geriatric research.
Purpose of the Study:
- To review the concept of frailty.
- To discuss newly developed preclinical frailty models.
- To compare human and animal frailty models.
Main Methods:
- Review of existing literature on frailty.
- Description of frailty phenotype- and frailty index-based models.
- Inclusion of mouse, rat, and canine models.
Main Results:
- Preclinical frailty models have been developed in the last decade.
- Mouse, rat, and canine models are utilized for frailty assessment.
- These models facilitate testing of frailty treatments and interventions.
Conclusions:
- Animal models are invaluable for studying frailty mechanisms and aging.
- Sex differences in frailty are considered in animal models.
- Availability of these models advances the study of frailty and age-related disorders.

00:59Tonicity in Animals
123.3K
The tonicity of a solution determines if a cell gains or loses water in that solution. The tonicity depends on the permeability of the cell membrane for different solutes and the concentration of nonpenetrating solutes in the solution within and outside of the cell. If a semipermeable membrane hinders the passage of some solutes but allows water to follow its concentration gradient, water moves from the side with low osmolarity (i.e., less solute) to the side with higher osmolarity (i.e.,...

Tonicity describes the amount of solute in a solution. The measure of the tonicity of a solution, or the total amount of solutes dissolved in a specific amount of solution, is called its osmolarity. Three terms—hypotonic, isotonic, and hypertonic—are used to relate the osmolarity of a cell to the osmolarity of the extracellular fluid that contains the cells. In a hypotonic solution, such as tap water, the extracellular fluid has a lower concentration of solutes than the fluid inside...

9.0K
Among all the organelles in an animal cell, only mitochondria have their own independent genomes. Animal mitochondrial DNA is a double-stranded, closed-circular molecule with around 20,000 base pairs. Mitochondrial DNA is unique in that one of its two strands, the heavy, or H, -strand is guanine rich, whereas the complementary strand is cytosine rich and called the light, or L, -strand. Compared to nuclear DNA, mitochondrial DNA has a very low percentage of non-coding regions and is marked by...

Animal and plant cells not only differ in their structure, function, and mode of nutrition but also in how they reproduce, specialize, and organize into complex structures.
Cell Division
Though both plant and animal cells divide by mitosis (for non-gametic cells) and meiosis (for gametic cells), they differ in the specifics of this process. Unlike animal cells, plant cells lack centrosomes — an organelle responsible for organizing the spindle fibers and segregating the chromosomes during...

01:26Assessment of the Mouth
1.1K
A thorough mouth assessment, including inspection and palpation of the lips, gums, tongue, tonsils, uvula, and pharynx, is crucial in detecting potential health issues. Diseases ranging from oral cancer to systemic conditions like diabetes could be identified early through careful oral examination. This article provides a detailed guide on conducting a comprehensive mouth assessment.
Mouth Inspection
The inspection begins with visually examining the mouth for symmetry, color, and size.

The two sources for collecting information are primary and secondary. After gathering information, interpretation and validation help to complete the data. The purpose of assessment is to establish data with the initial information, to interpret data about the patient's perceived needs and health problems, and to respond to these problems identified.
The nurse collects all aspects of the patient's health in the initial assessment, establishing priorities for ongoing focused assessments...
