Development and performance analysis of Si-CaP/fine particulate bone powder combined grafts for bone regeneration
Source, May 22, 2015
Background: Although autogenous bone grafts as well as several bone graft substitute material have been used for some time, there is high demand for more efficient and less costly bone-substitute materials. Silicon-substituted calcium phosphates (Si-CaP) and fine particulate bone powder (FPBP) prepa...
Simulation of the mechanical interlocking capacity of a rough bone implant surface during healing
Source, May 21, 2015
Background: When an implant is inserted in the bone the healing process starts to osseointegrate the implant by creating new bone that interlocks with the implant. Biomechanical interlocking capacity is commonly evaluated in in vivo experiments. It would be beneficial to find a numerical method to e...
A comparative study of mechanical strain, icariin and combination stimulations on improving osteoinductive potential via NF-kappaB activation in osteoblast-like...
Source, May 21, 2015
Background: The combination of drugs and exercise was the effective treatment in bone injure and rebuilding in clinic. As mechanical strain has potential in inducing the differentiation of osteoblasts in our previous study, the further research to investigate the combination of mechanical strain and...
Kinematic relationship between rotation of lumbar spine and hip joints during golf swing in professional golfers
Source, May 20, 2015
Background: Understanding the kinematics of the lumbar spine and hip joints during a golf swing is a basic step for identifying swing-specific factors associated with low back pain. The objective of this study was to examine the kinematic relationship between rotational movement of the lumbar spine ...
Investigating the possible effect of electrode support structure on motion artifact in wearable bioelectric signal monitoring
Source, May 15, 2015
Background: With advances in technology and increasing demand, wearable biosignal monitoring is developing and new applications are emerging. One of the main challenges facing the widespread use of wearable monitoring systems is the motion artifact. The sources of the motion artifact lie in the skin...
Anatomy packing with hierarchical segments: an algorithm for segmentation of pulmonary nodules in CT images
Source, May 14, 2015
Background: This paper proposes a semantic segmentation algorithm that provides the spatial distribution patterns of pulmonary ground-glass nodules with solid portions in computed tomography (CT) images. Methods: The proposed segmentation algorithm, anatomy packing with hierarchical segments (APHS),...
Reference point detection for camera-based fingerprint image based on wavelet transformation
Source, April 30, 2015
Background: Fingerprint recognition systems essentially require core-point detection prior to fingerprint matching. The core-point is used as a reference point to align the fingerprint with a template database. When processing a larger fingerprint database, it is necessary to consider the core-point...
Evaluation of an open access software for calculating glucose variability parameters of a continuous glucose monitoring system applied at pediatric intensive ca...
Source, April 24, 2015
Background: Continuous Glucose Monitoring (CGM) has become an increasingly investigated tool, especially with regards to monitoring of diabetic and critical care patients. The continuous glucose data allows the calculation of several glucose variability parameters, however, without specific applicat...
Model demonstrates functional purpose of the nasal cycle
Source, April 24, 2015
Background: Despite the occurrence of the nasal cycle being well documented, the functional purpose of this phenomenon is not well understood. This investigation seeks to better understand the physiological objective of the nasal cycle in terms of airway health through the use of a computational nas...
Wound perimeter, area, and volume measurement based on laser 3D and color acquisition
Source, April 24, 2015
Background: Wound measuring serves medical personnel as a tool to assess the effectiveness of a therapy and predict its outcome. Clinically used methods vary from measuring using rules and calipers to sophisticated methods, based on 3D measuring. Our method combines the added value of 3D measuring a...
