To conclude, the addition of polymers to GPCs resulted in little change to the Tw and Ts, however the compressive strength was found to decrease slightly. ASAP tests revealed that the cements may undergo some structural changes as a result of these additions. In the future perhaps the addition of organic polymers suspended in the liquid phase as part of the cement may yield improved results in this...
This work determines the effect of adding Titanium (Ti) to novel GPCs as Ti is used in the fabrication of many implantable materials due to some of its beneficial properties and excellent biocompatibility.
Welcome to the 37th Annual Northeast Bioengineering Conference (NEBEC) held at Rensselaer Polytechnic Institute (RPI) in Troy, NY. RPI is home to one of the first biomedical engineering departments in the country and hosting NEBC, in midst of our historic buildings and ongoing bio-renaissance at Rensselaer, is an opportune moment for us. We are particularly excited to have one of our graduates from...
Ultrasound has shown a great potential for serving as an outcome measure for localized scleroderma. High spatial resolution of ultrasound will aid to evaluate Echogenicity, Vascularity index and tissue thickness of localized scleroderma. Echogenicity is higher when the ultrasound waves reflected are lesser in value from any particular body organ. Vascularity index can be defined as the differences...
Due to the lack of regeneration capacity of Articular cartilage and very limited therapies available, it is necessary to design a construct which can mimic hydrogel behavior in articular cartilage. Gelatin and sulphated polysaccharide blends are used for that purpose of this study. Swelling behavior of these hydrogel is observed in both deionized water and phosphate buffer salin (PBS). For mechanical...
In this work, we will report on the design and validation of a Laminar Optical Tomography systems developed at RPI to image tissue-engineered constructs. The systems characteristics and image reconstruction methods will be presented and discussed. In silico and in vitro validation of the imaging platform based on phantom studies mimicking the optical properties of various bio-tissues will demonstrate...
The majority of the population will have low back pain in their lifetime. Low back pain correlates to degenerative pain disease (DDD) which has been linked to exposure to mechanical loads. Certain occupations involving heavy lifting also correlate with DDD. Analytical models of the spine provide estimates of loading in the spine. However, data is lacking explicitly measuring mechanical forces in the...
Shape memory polymer (SMP) substrates compatible with cell culture are presented that undergo programmed changes in surface topography on command to direct cell behavior. SMPs are a class of active materials that can be programmed to transition from a stable temporary shape to a permanent shape by a triggering mechanism, such as heat. Here, an SMP surface topography was programmed to transition from...
We hypothesized that nanoparticles designed to mimic the molecular interactions occurring between inflamed leukocytes and endothelium may possess specificity toward diverse host inflammatory responses. Here, superparamagnetic iron oxide (SPIO) nanoparticles were conjugated with integrin lymphocyte function-associated antigen (LFA)-1 Inserted (I) domain, engineered to mimic activated LFA-1 in leukocytes...
Ordered wrinkles have been used for a variety of applications and have found much interest in the field of mechanobiology, as topography has been shown to influence cell behavior. In this study we aimed to synthesize a biocompatible material that could be triggered to form wrinkles under physiological conditions. To achieve this aim, we used a shape memory polymer (SMP) substrate to induce surface...
Current lack of data for equine metacarpal bone mechanical properties hinders the design of plating systems for horses. Due to the difficulties of obtaining equine bones, as well as physical similarities found in deer bones, the goals of this study are to determine if deer (Odocoileus virginianus borealis) metacarpal bones are comparable to equine (Equus ferus caballus) third metacarpal bones and...
Medulloblastoma (MB) is the most common brain tumor in children. There are four distinct subtypes of MB, but patients with anaplastic/large cell have the worst prognosis. Since the morbidity is highly correlated with treatment for MB, the ability to distinguish aggressive (such as anaplastic/large cell) MB is crucial. We present a scheme that leverages quantitative image texture features (Haar, Haralick,...
The inverse problem in photoacoustic tomography (PAT) seeks to obtain the absorbed energy map from the boundary pressure measurements for which computationally intensive iterative algorithms exist. The computational challenge is heightened when the reconstruction is done using boundary data split into its frequency spectrum to improve source localization and conditioning of the inverse problem. The...
Intramuscular injections are a common medical procedure performed countless times on a daily basis; however the actual procedure of giving an injection is rather complicated and can be intimidating to nursing students new to the medical profession. The instrumented syringe discussed in this paper was conceived as a tool to help train individuals in proper injection procedure and technique. Utilizing...
Musculoskeletal disorders of the upper extremities, in particular the wrist and the shoulder, have become the largest class of injury in workers' compensation claims in the United States. Monitoring the development, progression, and treatment of degenerative orthopedic diseases, such as carpal tunnel and shoulder impingement syndrome, may be more effective when joint motions are assessed over long...
The transmissibility and the phase shift of the foot and ankle system (FAS) under the vertical sinusoidal vibration were studied as a function of the applied load. It was found that the increase of the applied load leads to the increase of the observed resonant frequency and stiffness of the system case.
