All animal procedures described here must be conducted in accordance with institutional animal ethics guidelines and approved by IACUC. All procedures must follow the principles of the 3Rs—Replacement, Reduction, and Refinement—and must be performed by trained personnel. Monitoring Animals for Signs of Pain and Distress Recognizing early signs of pain is essential for ethical animal research. Animals are routinely monitored using behavioral, physical, and physiological parameters that reflect...

Nursing Interventions I: Taxonomy of Nursing Interventions
0 Views •
2025
Nursing interventions are chosen as part of the planning process to achieve patient outcomes. Once nursing diagnoses are determined, the goals and outcomes are specified, then the nursing interventions are selected and individualized according to the patient's situation. A nursing intervention is a treatment or action based on scientific concepts and knowledge from the nursing, behavioral, and physical sciences. Identifying and prioritizing nursing interventions based on the desired outcome is...

Genetic Crosses

2023
To dissect genetic processes or create organisms with novel suites of traits, scientists can perform genetic crosses, or the purposeful mating of two organisms. The recombination of parental genetic material in the offspring allows researchers to deduce the functions, interactions, and locations of genes. This video will examine how genetic crosses were influential in developing Mendel's three laws of inheritance, which form the basis of our understanding of genetics. One genetic crossing...

Genetic Screens

Genetic screens are critical tools for defining gene function and understanding gene interactions. Screens typically involve mutating genes and then assessing the affected organisms for phenotypes of interest. The process can be “forward”, where mutations are generated randomly to identify unknown genes responsible for the phenotypes, or it can be “reverse”, where specific genes are targeted for mutation to observe what phenotypes are produced.Here, JoVE reviews various types of genetic...

Nursing Interventions II: Selecting and Classifying the Nursing Interventions

2023
Creating and executing a nursing diagnosis helps nurses plan care and guide patient, family, and community interventions. They are developed based on a patient's physical evaluation and support measuring the outcomes. It is not recommended to select random interventions throughout the planning process. Instead, consider the following six essential factors when choosing interventions: Characteristics of the nursing diagnosis Goals and expected outcomes Evidence basis (e.g., research or...
FAQs
These approaches change cell behavior in different ways. Gene editing directly alters genetic material, whereas gene transfer introduces genetic material into a cell. Gene silencing reduces the activity of a gene, and controlled expression changes when or how strongly a gene functions. Comparing these strategies helps researchers match the intervention to a biological question or therapeutic goal.
Engineered molecular tools provide the means to modify DNA or RNA, while delivery systems help bring those tools or genetic materials to the relevant cells. Their performance influences whether the intended cellular change occurs and how specifically it is produced. Consequently, both components are central to designing interventions for research, disease models, and cell-based applications.
Specificity matters because an intervention should produce the intended genetic or cellular change rather than unpredictable effects. Safety is equally important when researchers consider disease-associated mutations, inherited disorders, or cell-based therapies. Evaluating these concerns helps distinguish a useful intervention from one that changes cell function in ways that could compromise experimental interpretation or therapeutic development.
Researchers can alter, remove, replace, silence, or regulate genetic material and then examine how the cell or organism changes. Differences in development, physiology, or disease-related characteristics provide evidence about the gene’s contribution to those processes. This cause-and-effect strategy makes genetic intervention a valuable tool for connecting specific genes with biological functions.
Planning begins by identifying the genetic material or gene function relevant to the biological question. Researchers then select an approach, such as editing, transfer, silencing, or expression control, and choose suitable molecular tools and delivery systems. The resulting cellular or organismal changes are assessed to determine whether the intervention produced the intended functional outcome.
It is used when researchers need an organism with a specific genetic change or altered gene activity to study development, physiology, or disease. Such models can connect a genetic alteration with observable biological characteristics and help investigate disease-associated mutations. They therefore provide a research context for testing how genetic changes influence complex biological processes.
For inherited-disorder research, interventions can help investigate or potentially correct disease-associated mutations and clarify how they affect cell function. In cell-based therapies, changing genetic material or gene activity may help produce cells with desired characteristics. These applications remain closely linked to questions of specificity, safety, and ethical use before broader therapeutic adoption.
