Process Development for Fabricating 3D-Printed Polycaprolactone-Infiltrated Hydroxyapatite Bone Graft Granules: Effects of Infiltrated Solution Concentration and Agitating Liquid.

Bone grafts are commonly used in orthopedic and dental surgeries to facilitate bone repair and regeneration. A new type of bone graft, polycaprolactone-infiltrated three dimensionally printed hydroxyapatite (3DP HA/PCL), was previously developed by infiltrating polycaprolactone (PCL) into preformed three-dimensional-printed hydroxyapatite (3DP HA) that was fabricated using binder jetting technology combined with a low-temperature phase transformation process. However, when producing small granules, which are often used for bone grafting, issues of granule agglomeration emerged, complicating the application of this method.

Prototype development of bilateral arm mirror-like-robotic rehabilitation device for acute stroke patients.

During the early six months after the onset of a stroke, patients usually remain disabled with limbs weakness and need intensive rehabilitation. An increased number of stroke patients is countered with a reduced number of physical therapists. The development of medical robots to substitute therapists' work should be helpful.

Development of a DIY rehabilitation device for lower limb weakness in acute to subacute ischemic stroke.

Many patients have significantly lower limb weakness after getting a stroke. Continuous regular physical therapy is essential to promote the improvement of the weakness and overall outcomes. Home rehabilitation provides motivation and enhances regular rehabilitation in stroke patients.

The effect of temperature of eye irrigation solution to reduce corneal endothelial cell loss during phacoemulsification: an in vitro model study.

Objective: To compare the efficiency of eye irrigation solution (balanced salt solution: BSS) stored in a refrigerator and air-conditioned room to reduce the number of corneal endothelial cell loss during the process of phacoemulsification.

Material And Method: Porcine corneal endothelial cells (PCEC) isolated from porcine eyes were used as a model. The porcine eyes were obtained from a local slaughterhouse within 6 h after death and PCEC were cultured as standard method.

Fluid temperature at the corneal endothelium during phacoemulsification: comparison of an ophthalmic viscosurgical device and balanced salt solution using the finite element method.

Purpose: The purpose of this study was to estimate and compare the temperatures of two different anterior chamber solutions at the corneal endothelial level during phacoemulsification. An ophthalmic viscosurgical device (OVD) and balanced salt solution (BSS) were compared using the finite element method (FEM).

Materials And Methods: The thermal properties of an OVD (IAL-F) and BSS were studied in an experimental setting.
