Tiny medicine refers to the development of small easy use devices that can help in early diagnosis and treatment disease. Early is key successfully treating many diseases. Nanomaterial-based biosensors utilize unique properties biological physical nanomaterials recognize a target molecule effect transduction an electronic signal. In general, advantages nanomaterial-based are fast response, size, high sensitivity, portability compared existing large electrodes sensors. Systems integration...
The purpose of this study was to compare the biomechanical properties bicortical with unicortical screws in a proximal tibial fracture cadaveric model.Biomechanics laboratory at Level 1 trauma center.Eight pairs (4 male and 4 female) elderly (average age, 79 years; range, 63 104 years) tibiae.Osteotomies were performed tibia reproduce 41-C2 bicondylar pattern. 4.5-mm periarticular locking plates (Smith-Nephew, Memphis, TN) applied tibiae or 3 distal site. fixed tested by using materials...
Purpose: To investigate if a dental implant system with midsection covered by 3-dimensionally porous tantalum material would exhibit stability comparable traditional threaded titanium alloy and whether bone grow into the section. Methods: Three experimental 3 control implants were placed in individual mandibles of 8 dogs. Resonance frequency analysis assessed at 0, 2, 4, 8, 12 weeks healing. Histomorphometric backscattered scanning electron microscopic analyses examined presence ingrowth...
Engineering bone tissue is particularly challenging because of the distinctive structural features within a complex biochemical environment. In present study, we fabricated poly(l-lactic acid) (PLLA) electrospun nanofibers with random and aligned morphology immobilized morphogenic protein-2 (BMP-2) investigated how these signals modulate (1) in vitro osteogenic differentiation human mesenchymal stem cells (hMSCs) (2) vivo growth rate, mechanical properties, collagen assembly newly formed...
The spectral dimension has been widely used to understand transport properties on regular and fractal lattices. Nevertheless, it little studied for complex networks such as scale-free small world networks. Here we study the return-to-origin probability of random walks hierarchical networks, which can be either fractals or non-fractals depending weight shortcuts. Applying renormalization group (RG) approach Gaussian model, obtain exactly. While varies between $1$ $2$ case, remains at $2$,...
To investigate and compare outcomes following alveolar ridge preservation (ARP) in posterior maxilla mandible.Twenty-four patients (54 ± 3 years) with single tooth extraction were included. ARP was performed freeze-dried bone allograft collagen membrane. Clinical parameters recorded at re-entry. Harvested cores analysed by microcomputed tomography (micro-CT), histomorphometry immunohistochemistry.In both jaws, prevented height loss, but width significantly reduced approximately 2.5 mm....
This study investigates the fate of nitrogen species during nitrate reduction by nanoscale zero valent iron (NZVI) as well related kinetics. The NZVI used for experiments was prepared chemical without a stabilizing agent. pseudo first order kinetic constant at 30°C with an NZVI/nitrate ratio 1.25:1, which were reference conditions this study, 4.08 h−1 (R2 = 0.955). A mass balance established quantitative analysis aqueous-phase and gas-phase species. results confirm that converted to ammonium...
Bone regeneration through distraction osteogenesis (DO) is promising but remarkably slow. To accelerate it, autologous mesenchymal stem cells have been directly injected to the site in a few recent studies. Compared direct injection, scaffold-based method can provide earlier cell delivery with potentially better controlled distribution and retention. This pilot project investigated cell-delivery approach porcine mandibular DO model.Eleven adolescent domestic pigs were used for two major sets...
Abstract Calcium transfer into the mitochondrial matrix during sarcoplasmic reticulum (SR) Ca 2+ release is essential to boost energy production in ventricular cardiomyocytes (VCMs) and match increased metabolic demand. Mitochondria from female hearts exhibit lower mito-[Ca ] produce less reactive oxygen species (ROS) compared males, without change respiration capacity. We hypothesized that VCMs, more efficient electron transport chain (ETC) organization supercomplexes offsets deficit...
Abstract This paper deals with the order-batching problem in low-level picker-to-part warehousing system. In order batching, orders are combined as much possible so that picker can pick a set of at same time. For each three routing policies, traversal, return, and midpoint policy, we develop an efficient algorithm based on cluster analysis. To show validity algorithms, they compared existing terms total travel time number batches grouped. Keywords: WarehouseOrder-batchingCluster analysis...
The level of structural detail that can be acquired and incorporated in a finite element (FE) analysis might greatly influence the results microcomputed tomography (μCT)-based FE simulations, especially when relatively large bones, such as whole vertebrae, are concern. We evaluated effect scanning reconstruction voxel size on μCT-based analyses human cancellous tissue samples for fixed- free-end boundary conditions using different combinations scan/reconstruction size. found bone volume...
Despite a general understanding that bone quality contributes to skeletal fragility, very little information exits on the age-dependent fatigue behavior of human bone. In this study four-point bending tests were conducted aging in conjunction with analysis stiffness loss and preliminary investigation nanoindentation based measurements local tissue histological evaluation resultant tensile compressive damage identify mechanism responsible for increase age-related fragility. The results...
