Source: Madeline Lassche, MSNEd, RN and Katie Baraki, MSN, RN, College of Nursing, University of Utah, UT The purpose of peripheral intravenous catheter (PIV) insertion is to infuse medications, perform intravenous (IV) fluid therapy, or inject radioactive tracers for special examination procedures. Placing a PIV is an invasive procedure and requires the use of an aseptic, no-touch technique. Common IV venipuncture sites are the arms and hands in adults and the feet in children. According to...

The Giant Fiber System is a simple neuronal circuit of adult Drosophila melanogaster containing the largest neurons in the fly. We describe the protocol for monitoring synaptic transmission through this pathway by recording post synaptic potentials in dorsal longitudinal (DLM) and tergotrochanteral (TTM) muscles following direct stimulation of the Giant Fiber interneurons.

Construction of a fosmid library with environmental genomic DNA isolated from the vertical depth continuum of a seasonally hypoxic fjord is described. The resulting clone library is picked into 384-well plates and archived for downstream sequencing and functional screening by the application of an automated colony picking system.

Central Venous Catheter Insertion: Subclavian Vein

2023
Source: James W Bonz, MD, Emergency Medicine, Yale School of Medicine, New Haven, Connecticut, USA Central venous access is necessary in a multitude of clinical situations for hemodynamic monitoring, medication delivery, and blood sampling. There are three veins in the body that are accessed for central venous cannulation: the internal jugular, the subclavian, and the femoral vein. Central venous access via the subclavian vein has several advantages over other possible locations. The subclavian...
FAQs
Recognition of the DNA ends provides the starting point for accurate processing and strand transfer. The pathway must distinguish the relevant sequence termini before excision-related processing or insertion can proceed. This step helps determine which DNA fragment participates in the reaction and supports the formation of junctions that host repair systems can subsequently resolve.
Target-site selection determines where the mobilized or engineered DNA sequence will be placed, whereas strand transfer creates the initial connection between that sequence and the recipient DNA. Treating them as distinct steps clarifies how insertion location and molecular joining contribute separately to genome rearrangement and to the eventual stability of the inserted fragment.
Strand transfer can leave DNA junctions that are not yet fully restored to a continuous genome. Host enzymes repair these junctions, completing the molecular connection and helping preserve genome integrity. The outcome therefore depends not only on the insertion reaction itself but also on how cellular repair processes resolve the structures produced during re-insertion.
A useful analysis follows the sequence of recognition, DNA processing or excision, target-site selection, strand transfer, and junction repair. Examining these stages separately helps identify where a sequence is mobilized, how its destination is chosen, and how the host restores DNA continuity. This framework also connects molecular events with observed genome rearrangements.
Transposon movement provides a basis for transposon mutagenesis, in which insertion-related genome changes can be used to study genetic effects. The pathway connects the transposon’s movement with its placement in a new genomic context and the repair of the resulting junctions. Studying these events helps relate DNA mobility to variation within biological systems.
Engineered DNA fragments can be examined through the same broad sequence of end recognition, target selection, strand transfer, and junction repair. This makes the pathway relevant to genome engineering because successful placement requires both molecular joining and host processing of the resulting DNA ends. Its study helps explain how designed sequence changes become integrated into genomes.
