Robotic‐arm assisted total knee arthroplasty has a learning curve of 16 cases and increased operative time of 12 min

Mei Lin Tay, Matthew Carter, Nina Zeng, Matthew L. Walker, more

ANZ Journal of Surgery > 92 > 11 > 2974 - 2979

Background Robotic‐arm assisted systems are increasingly used for knee arthroplasty, however introduction of new systems can involve a learning curve. We aimed to define the learning curve in terms of operative time and component placement/sizing of a robotic system for total knee arthroplasty (TKA) in a team of experienced surgeons, and to investigate mid‐term patient outcomes. Methods A total...

Safety of non‐ablative fractional laser for acne scars within 1 month after treatment with oral isotretinoin: A randomized split‐face controlled trial

Sandeep S. Saluja, Matthew L. Walker, Erika M. Summers, Payam Tristani‐Firouzi, more

Lasers in Surgery and Medicine > 49 > 10 > 886 - 890

Background and Objective Based on reports of poor wound healing and scarring, it is currently recommended that patients wait 6 months after completion of oral isotretinoin therapy before the safe initiation of laser treatment. Our aim was to evaluate the safety of non‐ablative fractional laser (NAFL) treatment for acne scars within 1 month after isotretinoin therapy. Study Design/Methods This was...

Background Neutral mechanical alignment (MA) in total knee arthroplasty (TKA) aims to position femoral and tibial components perpendicular to the mechanical axis of the limb. In contrast, kinematic alignment (KA) attempts to match implant position to the prearthritic anatomy of the individual patient with the aim of improving functional outcome. However, comparative data between the two techniques...

Three‐dimensional electron microscopy reconstruction and cysteine‐mediated crosslinking provide a model of the type III secretion system needle tip complex

Martin Cheung, Da‐Kang Shen, Fumiaki Makino, Takayuki Kato, more

Molecular Microbiology > 95 > 1 > 31 - 50

Type III secretion systems are found in many Gram‐negative bacteria. They are activated by contact with eukaryotic cells and inject virulence proteins inside them. Host cell detection requires a protein complex located at the tip of the device's external injection needle. The Shigella tip complex (TC) is composed of IpaD, a hydrophilic protein, and IpaB, a hydrophobic protein, which later forms part...

Cell morphology classification and clutter mitigation in phase-contrast microscopy images using machine learning

Diane H. Theriault, Matthew L. Walker, Joyce Y. Wong, Margrit Betke

Machine Vision and Applications > 2012 > 23 > 4 > 659-673

We propose using machine learning techniques to analyze the shape of living cells in phase-contrast microscopy images. Large scale studies of cell shape are needed to understand the response of cells to their environment. Manual analysis of thousands of microscopy images, however, is time-consuming and error-prone and necessitates automated tools. We show how a combination of shape-based and appearance-based...
