However, the use of these materials has not achieved a correct fixation and reduction of all bone fragments. Therefore, an adhesive for bones would provide a simple and quick method to fix this kind of fractures. The aim of this work is to propose and to evaluate an adhesive based on chitosan hydrogels that could have a potential use as a bone adhesive underwater and will not develop cytotoxic effects. Ionically and covalently crosslinked hydrogels based on chitosan were used in this study. Mechanical studies revealed that only covalently crosslinked hydrogels maintain their TBS at physiological condition with respect to the dry environment. In addition, it was observed that the TBS, using only covalently crosslinked hydrogels adhesives, dramatically changes as a function of time and its behavior increases as calcium carbonate and hydroxyapatite is added. Finally, in vitro cell testing of covalently crosslinked hydrogel with calcium carbonate and hydroxyapatite exhibited excellent biocompatibility. Therefore, this formulation is proposed as a potential candidate for clinical use in orthopedic surgery.https://www.blackhillsdancecentre.com/wp-content/plugins/formcraft/file-upload/server/content/files/1626c7215852ef---carrier-fe4anb006-installation-manual.pdf Keywords: Chitosan, bone adhesive, cancellous bone, fibroblast, hydrogel, underwater adhesion Additional information Acknowledgments We thank Dr Pablo Arbelaez for his assistance in the bone surface reconstruction.

The wiring of the LVDT amplifiers was modified after consulting the manufacturer. After the re-wiring, the oscillatory noise has been under control to a certain extent. The evaluation on the effect of the noise is ongoing. 2) The calibration indicated that the reading of WinTest meters for RDP LVDTs didn't give a linear response to the input from calibration micrometer. The test showed that the output of RDP amplifiers (DR7AC) was responding linearly to the input. However, the both the readouts of PCI controller and the meters of Bose WinTest delivered a distorted signal (Figure 44). It is believed that there is something happening with the PCI connector and reserved PCI channels. The Bose has been requested to help us analyze the problem. A detailed examination showed that a 3-wire was used in the connection between DR7AC amplifier and the PCI controller. This connection is different from the 6-wire connection of Bose Disp 1 to the same controller. The wiring was modified according to the ElectroForce Dual LM2 TestBench Reference Manual (2012)5 as shown in Figure 45 and the linearity was obtained accordingly.

A tissue specimen was subjected to simple shear between two parallel, rigid acrylic plates, with a linear motor creating a translational sinusoidal displacement of the specimen via the upper plate, and the lower plate transmitting the harmonic shear force resulting from the viscoelastic response of the specimen. The displacement of the specimen was measured by a linear variable differential transformer whereas the shear force was detected by a piezoelectric transducer. The frequency response characteristics of these system components were assessed by vibration experiments with accelerometers.

This paper describes the design and validation of a custom-built, controlled-strain, linear, simple-shear rheometer system capable of direct empirical measurements of viscoelastic shear properties at phonatory frequencies. Preliminary results showed that the rheometer can provide valid and reliable rheometric data of vocal fold lamina propria specimens at frequencies of up to around 250 Hz, well into the phonatory range. INTRODUCTION Phonation is characterized by a flow-induced self-sustained oscillation of the vocal fold mucosa, involving primarily the vocal fold cover, or superficial layer of the lamina propria. Valid viscoelastic data were obtained at frequencies of up to 80 Hz, and when the gap size was decreased from 0.2 to 0.1 mm, the data could be valid for up to around 100 Hz.http://vibrosystem.ro/wp-content/plugins/formcraft/file-upload/server/content/files/1626c7228cf852---carrier-fe4anf002-manual.pdf Chan (2004) introduced the use of controlled-strain torsional rheometry, with a torsional shear strain applied to a tissue specimen and the shear stress response measured. Valid viscoelastic data of 17 canine vocal fold mucosa specimens were obtained at frequencies of up to around 50 Hz. Further measurements were made by Klemuk and Titze (2004) using the CVO-120 rheometer of Titze et al. (2004), but in controlled-strain mode. Phonosurgical biomaterials such as collagen (Zyderm), a thiolated hyaluronic acid (HA) hydrogel (HA-DTPH), and micronized alloderm (Cymetra) were tested at frequencies of up to around 80 Hz. The highest frequencies at which valid data were obtained were found to be around 40 Hz for HA-DTPH, and around 80 Hz for Zyderm and Cymetra ( Klemuk and Titze, 2004 ). Although the frequencies of viscoelastic measurement had improved in previous studies, they were nonetheless still at the low end of the phonatory range ( Chan, 2004; Klemuk and Titze, 2004; Titze et al., 2004 ). Viscoelastic characterization of vocal fold tissues should be done at phonatory frequencies in order that the rheometric data become directly applicable to phonation, without having to rely on extrapolations or theoretical predictions ( Chan, 2001, 2004; Chan and Titze, 2000 ). This paper reports the design and validation of a custom-built, controlled-strain, linear, simple-shear rheometer system capable of direct empirical measurements of viscoelastic properties at frequencies in the phonatory range. The resulting shear force F due to the viscoelastic response of the specimen is transmitted to the lower plate, and can then be detected by a transducer. A linear, simple-shear deformation is applied to a tissue or material specimen by the upper plate with a small-amplitude translational sinusoidal displacement x. A harmonic shear force F due to the viscoelastic response of the specimen is transmitted to the lower plate, separated from the upper plate by a gap size d.AUTOSKOLA-SCP.COM/files/conia-air-conditioners-manuals.pdf The contact area A between the specimen and the upper plate can be visualized from directly above through the transparent upper plate. The area of contact between the specimen and the plates ( A ) can be estimated by analysis of scaled images taken from directly above the upper plate. METHOD Design of the simple-shear rheometer The EnduraTEC ElectroForce (ELF) 3200 mechanical testing system (Bose Corporation, ElectroForce Systems Group, Eden Prairie, MN) was chosen as a base system to provide several key design criteria that are critical to the development of a controlled-strain rheometer for the measurements of tissue viscoelasticity at high frequencies. First, the system is capable of prescribing a precise oscillatory deformation through a linear motor. The linear motor design is modified from that of Bose subwoofers, involving a lightweight permanent magnet suspending in a controlled electromagnetic field, producing translational, oscillatory motion of the permanent magnet upon alternations of the electromagnetic field. The design does not include any mechanical seals or bearings, but the moving permanent magnet is attached directly to an actuator and a fixture through which a specimen is mounted and deformed. As a result, frictional energy loss in the driving mechanism of the motor is minimized, enabling the motor to maintain the same sinusoidal displacement at various amplitudes over a wide range of frequency. This is facilitated by displacement feedback control, which monitors the actual displacement of the actuator real time through a linear variable differential transformer (LVDT), such that the target prescribed displacement is closely approximated. Second, it is crucial that the shear force resulting from the viscoelastic response of the specimen upon deformation is detected by a force transducer capable of accurate and reliable measurements over a wide range of frequency. This is especially challenging as the magnitude of the force response depends on the elastic modulus of the specimen, and is typically in the millinewton range or smaller for soft tissue specimens. Piezoelectric force transducers designed with quartz crystals generating an electrical potential proportional to an applied force have the natural advantage of detecting dynamic forces at high frequencies. The output impedance of such transducers must be low ( Third, inertial effects due to the system and the specimen should be minimized, whereas the frequency of system resonance should be maximized, in order to minimize measurement errors and time-dependent artifacts caused by system inertia, sample inertia, and system resonance ( Chan, 2004; Titze et al., 2004 ). The moving parts of the ELF 3200 system (shaft of the linear motor, the actuator, and the fixtures or plates in contact with the specimen) can be fabricated with lightweight acrylic material, leading to minimal inertial time delays and contributing to increase the system resonant frequency. The linear motor design enabling minimal friction in the moving parts over a wide range of frequency will contribute to the minimization of the system inertial effects during oscillation. Also, a piezoelectric force transducer with significant stiffness against deformation will also facilitate a higher system resonant frequency. The shear force resulting from the viscoelastic response of the specimen to the applied strain is detected by a piezoelectric quartz force transducer (PCB Model 209C12; PCB Piezotronics, Depew, NY) rigidly attached to a stationary lower plate. Open in a separate window Figure 2 Schematic of the custom-built, controlled-strain, linear, simple-shear rheometer system. A LVDT displacement transducer (Schaevitz MHR 250) is attached to the shaft of the linear motor through an actuator, for estimation of shear strain of the specimen. The resulting shear force ( F ) at the lower plate is detected by a piezoelectric force transducer (PCB Model 209C12). A normal load transducer measures the compressive force between the specimen and the plates. A micrometer allows one to adjust the gap size ( d ) between the two plates to accommodate specimens of varying dimensions. Mechanical testing is performed in an environmental chamber at controlled temperature and humidity. The lower plate in contact with the tissue specimen is capable of displacement in the vertical (perpendicular) direction for adjustment of the gap size through a micrometer. One purpose of the normal load transducer is to facilitate establishing a zero gap reference, when the normal force changes from zero to nonzero upon contact between the two tissue plates. The monitoring of normal load is also helpful for testing specimens of vastly different dimensions and volumes. A digital camera is mounted directly above the chamber and photos of the specimen mounted between the tissue plates are taken. For the viscoelastic measurements to truly reach into the phonatory range, it is critical to validate the rheometer by establishing its frequency response characteristics, as well as the reliability and validity of the measurements. Two key system components, i.e., the LVDT displacement transducer and the piezoelectric force transducer, were validated by an assessment of their frequency response over a frequency range of up to 400 Hz, as detailed below. In order to assess the accuracy of displacement measurements of the LVDT as a function of frequency, an accelerometer (PCB Model 353B18; PCB Piezotronics, Depew, NY) was attached to the actuator of the ELF 3200 system. The target displacement was achieved by displacement feedback control, and was detected by the LVDT as the nominal displacement. The actual displacement of the actuator was derived from the acceleration measured by the accelerometer. A flat response with little deviation ( The nominal displacement amplitude given by the output of the LVDT was compared to the actual displacement amplitude of the actuator estimated from the accelerometer output. The ratio of the nominal displacement amplitude to the actual displacement amplitude from Eq. 24 is an indication of the frequency response of the LVDT. Two separate procedures were conducted to assess the accuracy of the force measurements at low frequency, as well as the transducer response at higher frequencies. Strain gauges are generally used for the accurate measurements of static and low-frequency forces due to the inherent stability of DC signals generated by semiconductors. For calibration, translational sinusoidal deformation at 1.0 Hz was applied and the gain of the PCB signal conditioning interface was adjusted to match the piezoelectric transducer force output to that of the strain gauge. The linearity is verified by varying the amplitude of deformation. The shaft of the piezoelectric force transducer is attached to the actuator through a tissue clamp. The shaft of a rigidly fixed, calibrated strain gauge (Sensotec Model 31) is attached to the body of the piezoelectric force transducer. Under sinusoidal oscillation at 1.0 Hz, the gain of the piezoelectric force transducer is adjusted to achieve identical dynamic output voltages from both the piezoelectric transducer and the strain gauge. Three different levels of mass were attached to the shaft of the piezoelectric transducer, in order to vary the effective mass subjected to oscillation. They included a titanium tissue plate, an acrylic tissue plate, and no tissue plate (with the adapter only). At each frequency, the dynamic force output was measured by the piezoelectric transducer while the acceleration of the system was measured by the accelerometer. Open in a separate window Figure 4 Schematic of the setup for establishing the frequency response of the piezoelectric force transducer. The body of the piezoelectric force transducer is attached to the actuator, and varying mass (acrylic tissue plate, titanium tissue plate, or no tissue plate) is attached to the shaft of the transducer through an adapter. An accelerometer (PCB Model 353B18) is also attached to the actuator simultaneously for the measurement of acceleration. Estimation of system noise level After establishing the accuracy and the frequency response of the LVDT displacement transducer and the piezoelectric force transducer, it was also important to determine the system signal-to-noise level, to reflect the functional frequency range within which measurements can be made with minimum errors. The system signal level was defined as the magnitude of the piezoelectric transducer force output resulting from the testing of specific specimens, whereas the system noise level was defined as the force output amplitude due to the electrical noise inherent in the system. The goal of this assessment was to compare the system noise level with the signal level, so as to determine the frequencies at which noise is or is not acceptable. For system noise, oscillatory shear deformation was conducted with no specimens mounted in the rheometer, under the exact same set of conditions as above. Validation with a standard polymer material The ANSI S2.21 standard material with known viscoelastic properties was used to validate the viscoelastic measurements of the rheometer system (American National Standards Institute, ANSI S2.21, 1998 ). This standard material was made for calibrating equipment that measures the dynamic mechanical properties of viscoelastic materials. Three samples of the standard material were fabricated according to the standard procedure of ANSI S2.21, with the molar concentrations of the prepolymer and the chain extender reduced such that the shear modulus of the material is 1000 times lower (on the order of kPa rather than MPa) to be a closer match of the human vocal fold. Laryngeal specimens were also obtained from two additional subjects who underwent total laryngectomy due to supraglottic or thyroid cancer that did not involve the true vocal folds. Most of the subjects were Caucasians, but race was not a factor in the tissue procurement procedure. All of the subjects were nonsmokers, with no history of laryngeal disease and pathology. Physical examination of the laryngeal specimens revealed that the true vocal folds of all subjects were normal. The tissue procurement protocol and the experimental protocol were approved by the Institutional Review Board of the University of Texas Southwestern Medical Center. The cadaveric larynges were acceptable since previous research showed that the viscoelastic shear properties of vocal fold tissues are not significantly altered after 24 h of postmortem storage in saline at room temperature ( Chan and Titze, 2003 ). Vocal fold specimens were dissected from the larynges with instruments for phonomicrosurgery, similar to the procedure of Chan and Titze (1999). Briefly, an incision was first made on the superior surface of the vocal fold epithelium with a surgical blade (No. 11), so that the vocal fold cover (epithelium and the superficial layer of the lamina propria) could be separated from the vocal ligament (middle layer and deep layer of the lamina propria) through blunt dissection with a spatula similar to the Bouchayer spatula. This separation was facilitated by the natural plane of dissection between the superficial layer and the middle layer of the lamina propria. The vocal fold cover was then isolated from the larynx and kept in phosphate-buffered saline solution at a p H of 7.4 at room temperature prior to rheometric measurements. Two testing protocols were conducted with the rheometer. This served to identify the linear viscoelastic region of the specimens, i.e.
