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.

This video demonstrates the procedure for in vivo intracellular recording of photoreceptor cells in the eye of a butterfly and determining the spectral sensitivity of individual cell types. This technique enables the study of sensitivities of individual photoreceptor cells to different light stimuli.

Source: Julianna Jung, MD, FACEP, Associate Professor of Emergency Medicine, The Johns Hopkins University School of Medicine, Maryland, USA For unstable patients requiring urgent administration of medications, fluids, or blood products, establishing vascular access quickly is essential. However, there are many factors that can complicate placement of a peripheral intravenous cannula (PIV), and it is extremely common for PIV attempts to fail. PIV placement may be technically challenging in small...

Source: Rachel Liu, BAO, MBBCh, Emergency Medicine, Yale School of Medicine, New Haven, Connecticut, USA A tension pneumothorax is a life-threatening situation in which excess air is introduced into the pleural space surrounding the lung, either through trauma to the chest cavity or as a spontaneous leak of air from the lung itself. Air trapped within the pleural space causes separation of the lung from the chest wall, disrupting normal breathing mechanisms. Pneumothorax may be small without...

We describe here a protocol for microinjection in the rodent brain that uses quartz needles. These needles do not produce detectable tissue damage and ensure reliable delivery even in deep regions. Moreover, they can be adapted to research needs by personalized designs and can be re-used.
FAQs
The two plastic wings provide a stable point for holding and positioning the needle during venipuncture. This support helps the clinician control the device while the needle enters a vein and while the tubing remains connected to another component. Stabilization is especially relevant when precise positioning matters, such as with small, superficial, fragile, or difficult-to-access veins.
Orienting the bevel upward establishes the described insertion position for entering the vein. Combined with holding the wings, this orientation helps the clinician maintain controlled needle placement rather than relying on the tubing for manipulation. The arrangement supports deliberate venipuncture and may contribute to the improved positioning and patient comfort associated with the device.
Flexible tubing allows the inserted needle to connect with a syringe, collection tube, or infusion line without requiring that connection to be held directly at the needle. This separates the access point from the connected equipment and supports controlled blood collection or fluid delivery. The tubing therefore helps adapt the same device to several brief venous-access tasks.
A clinician positions the needle with the bevel facing upward, inserts it into the selected vein, and holds the wings to stabilize the device. The tubing is then connected to a syringe, collection tube, or infusion line, depending on the task. Because the device is intended for brief procedures, careful securement remains important throughout use.
The tubing can connect to a syringe for controlled access, a collection tube for obtaining blood, or an infusion line for delivering fluids. The appropriate connection depends on whether the immediate goal is collection or a short intravenous treatment. This flexibility allows one winged infusion set design to support different forms of venous access in medicine.
Clinicians may select this device when a vein is small, fragile, superficial, or difficult to access, or when the planned intervention is brief. Its wings can improve positioning and patient comfort, but the needle requires careful securement and is generally intended for short procedures. These characteristics make it more suited to limited access than prolonged use.
