The protocol describes how to engineer a perfusable vascular network in a spheroid. The spheroid's surrounding microenvironment is devised to induce angiogenesis and connect the spheroid to the microchannels in a microfluidic device. The method allows the perfusion of the spheroid, which is a long-awaited technique in three-dimensional cultures.

Spin–Spin Coupling: Two-Bond Coupling (Geminal Coupling)
0 Views •
2024
Two NMR-active nuclei bonded to a central atom can be involved in geminal or two-bond coupling. Geminal coupling is commonly seen between diastereotopic protons in chiral molecules and unsymmetrical alkenes, among others. The central atom need not be NMR-active because its electrons are affected by the electron polarization of the spin-active atoms. However, spin information is transmitted less effectively than in one-bond coupling, and 2J values are usually weaker than 1J values. The energy of...

Spin–Spin Coupling: Three-Bond Coupling (Vicinal Coupling)

2024
Vicinal or three-bond coupling is commonly observed between protons attached to adjacent carbons. Here, nuclear spin information is primarily transferred via electron spin interactions between adjacent C‑H bond orbitals. This generally favors the antiparallel arrangement of spins, so 3J values are usually positive. The extent of coupling depends on the C‑C bond length, the two H‑C‑C angles, any electron-withdrawing substituents, and the dihedral angle between the involved orbitals. The...

Source: Vy M. Dong and Faben Cruz, Department of Chemistry, University of California, Irvine, CA This experiment will demonstrate the concept of a palladium-catalyzed cross coupling. The set-up of a typical Pd-catalyzed cross coupling reaction will be illustrated. Pd-catalyzed cross coupling reactions have had a profound effect on how synthetic chemists create molecules. These reactions have enabled chemists to construct bonds in new and more efficient ways. Such reactions have found widespread...
FAQs
The pins provide fixed points for positioning the vessel ends. Surgeons place each end over the pins, evert the vessel walls, and bring the rings together. This sequence aligns the exposed vessel edges around the circumference, allowing them to form an anastomosis rather than relying on individually placed sutures. The standardized geometry supports consistent connection and blood-flow continuity.
Eversion turns the vessel edges outward before the rings are joined. This places the aligned edges in direct apposition, meaning they meet evenly at the connection site. Proper positioning helps the two vessel ends form a continuous pathway for blood flow and allows the coupling rings to maintain the standardized alignment required for the anastomosis.
The device can create the vessel connection without conventional suturing by using pins, eversion, and paired rings to align and secure the vessel ends. This replaces the need to construct the anastomosis through individually placed stitches. Its standardized approach may support more efficient surgery and consistent vascular patency, particularly when a dependable venous connection is needed.
The provided clinical context identifies venous anastomoses as the primary use, especially in reconstructive and plastic surgery. In free-flap procedures, the connected vessels must provide a reliable pathway that supports tissue survival. Coupling rings offer standardized alignment for this connection, making the device relevant where consistent venous patency is an important surgical outcome.
The surgeon first positions the vessel ends over the small pins on separate coupling rings. Each vessel wall is then everted over its ring so the edges are exposed and aligned. Finally, the rings are brought together, placing the vessel edges into apposition and completing the anastomosis. This workflow establishes the restored pathway for blood flow.
They are used primarily during venous anastomoses in reconstructive and plastic surgery, including free-flap procedures. In these operations, successful vessel connection is essential for maintaining the blood-flow pathway that supports transplanted tissue. The device’s standardized alignment can contribute to efficient microsurgery and consistent patency, making it useful when reliable vascular connection is required for tissue survival.
