Q Suture Technique: A Suturing Technique to Reduce Gap Formation and Increase Tensile Strength in Tendon Repair

2025
In this video, we demonstrate suturing techniques — core suture and Q suture — to repair the foot flexor tendon in an ex vivo porcine model. Q sutures enhance the strength of the core suture in tendon repair and decrease gapping at the tendon repair site.

Source: Tamara M. Powers, Department of Chemistry, Texas A&M University The glovebox provides a straightforward means to handle air- and moisture-sensitive solids and liquids. The glovebox is what it sounds like: a box with gloves attached to one or more sides, which allows the user to perform manipulations within the glovebox under an inert atmosphere. For manipulations under inert atmospheres, chemists can choose between Schlenk or high-vacuum techniques and a glovebox. Schlenk and...

Sutures of the Skull

The human skull is composed of several bones that come together to protect the brain and support the structures of the face. The junctions where these bones meet are called sutures. Sutures are immobile joints between adjacent bones of the skull. The narrow gap between the bones is filled with dense, fibrous connective tissue that unites the bones. The long sutures located between the skull bones are not straight but instead follow irregular, tightly twisting paths. These twisting lines tightly...

We describe an electrochemical sensor assay method for rapid bacterial detection and identification. The assay involves a sensor array functionalized with DNA oligonucleotide capture probes for ribosomal RNA (rRNA) species-specific sequences. Sandwich hybridization of target rRNA with the capture probe and a horseradish peroxidase-linked DNA oligonucleotide detector probe produces a measurable amperometric current.

This article will demonstrate how to monitor glutamine dynamics in live cells using FRET. Genetically encoded sensors allow real-time monitoring of biological molecules at a subcellular resolution. Experimental design, technical details of the experimental settings, and considerations for post-experimental analyses will be discussed for genetically encoded glutamine sensors.
FAQs
When the attached tissue changes shape, the sensing element deforms with it rather than remaining mechanically isolated. That deformation alters a measurable property, such as electrical resistance or capacitance, creating a signal that can be recorded across time. The resulting time-dependent pattern can therefore represent changes in stretch, contraction, or pressure acting at the tissue interface.
Sutures contribute more than physical attachment: they help maintain close, stable contact while the biological tissue moves. This stability is important because shifting contact could make recorded changes reflect device movement rather than physiology. By remaining aligned with the tissue, a sutured sensor is suited to measurements that must follow mechanical events repeatedly over an extended monitoring period.
Different sensing readouts capture deformation through different electrical changes. A resistance-based element reports a change in electrical resistance, whereas a capacitance-based element reports a change in capacitance; other signal types may also be possible. This distinction matters because the recorded signal must be interpreted as a response to tissue mechanics, including stretching, contraction, or pressure.
Using a sutured sensor requires positioning the sensing element on the tissue of interest, securing it with surgical stitches, and recording its signal as the tissue changes. The measurement is then followed over time rather than treated as a single observation. In a biological experiment, this workflow links the device output to ongoing wound, organ, or tissue behavior.
Application depends on the mechanical event being studied. In wound-healing research, the device can track changing tissue behavior; on organs, it can follow motion; and in tissue studies, it can measure strain or mechanical forces. These use cases extend observation beyond occasional inspection by producing a continuous record of physiological changes while the sensor remains attached.
In biology, the main research value is the ability to connect tissue mechanics with physiological change over time. Measurements from these devices can help investigators study how wounds close, how organs move, or how forces act on tissue. The same design principle also supports development of implantable systems intended to monitor physiology and contribute to responsive medical technologies.
