In order to examine gene expression in the pupal wing tissue of Bicyclus anynana, we present an optimized protocol for in situ hybridizations using riboprobes. We also provide guidelines for the further optimization of this protocol for use in pupal wings of other Lepidopteran species.

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...

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, including vascular access, vasopressor and caustic medication delivery, central venous pressure monitoring, intravascular device delivery (pacing wires, Swann-Ganz catheters), volume resuscitation, total parental nutrition, hemodialysis, and frequent phlebotomy. Safe reliable placement of a central venous catheter (CVC) in...
FAQs
The wing-shaped grips provide a stable surface for holding and positioning the needle after it enters a vein. Flexible tubing separates the connection point from the insertion site, allowing a syringe, blood-collection tube, or infusion line to connect without directly handling the needle. Together, these features help limit movement during short-term procedures.
Its compact design supports venipuncture when the available vessel is small or access is challenging. The wings help maintain the needle’s position once venous entry is achieved, while the tubing permits collection or delivery away from the insertion site. This arrangement can make controlled sampling or administration more practical in these situations.
The tubing provides a flexible pathway between the needle and the external device used for the procedure. Depending on the task, it can connect with a syringe, blood-collection tube, or infusion line. This allows the same access point to support blood collection, medication administration, or fluid delivery while the needle remains positioned in the vein.
Use begins by placing the needle into a vein, then stabilizing the insertion site with the wing-shaped grips. The tubing is connected to the intended syringe, blood-collection tube, or infusion line, and the selected procedure is performed through that pathway. The approach is intended for short-term access rather than extended placement.
Researchers may choose this device when an experiment requires controlled blood collection or administration of a substance through a vein. It is especially relevant when veins are small, difficult to access, or susceptible to movement at the insertion site. The method can support repeatable handling of samples or administered materials during a defined short-term procedure.
In biomedical research, the device can provide controlled access for collecting blood or administering medications and fluids. Its stabilized insertion site may reduce movement during these actions, helping maintain the intended connection while material is collected or delivered. The resulting setup is useful when researchers need a practical link between a vessel and an external collection or infusion system.
