Robotically adjustable kinematics in a wrist-driven orthosis eases grasping across tasks [PDF]

Without finger function, people with C5-7 spinal cord injury (SCI) regularly utilize wrist extension to passively close the fingers and thumb together for grasping. Wearable assistive grasping devices often focus on this familiar wrist-driven technique to provide additional support and amplify grasp force.

Multifunctional Hydroxyapatite Coated with Gallium Liquid Metal‐Based Silver Nanoparticles for Infection Prevention and Bone Regeneration

Advanced Functional Materials, EarlyView.
A multifunctional hydroxyapatite (HAp) coating integrated with silver‐gallium liquid metal nanoparticles (HAp‐Ag‐GaNPs) exhibits dual antibacterial and osteogenic properties. It effectively inhibits Gram‐positive and Gram‐negative bacteria, including resistant strains, while enhancing bone regeneration.

Reconstruction of finger composite defects with perforator free flap from the superficial palmar branch of radial artery

Turkish Journal of Plastic Surgery, 2018
Background: Relatively rare scarce number of flaps are used to repair composite defects occurring as a consequence of finger injuries. The main objective in this study is reconstruction of the composite defects of the fingers to share in our study; we ...

The use of external fixators for finger injuries: pin placement and tethering of the extensor hood.

Journal of Bone and Joint Surgery-british Volume, 1998
External fixation is useful for the treatment of selected injuries to the hand. Some authors have suggested that external fixation of a phalanx may tether the extensor hood, thereby hindering active movements and predisposing to permanent adhesions ...

Intraoral Drug Delivery: Bridging the Gap Between Academic Research and Industrial Innovations

Advanced Functional Materials, EarlyView.
Intraoral drug delivery offers a promising route for systemic and localized therapies, yet challenges such as enzymatic degradation, limited permeability, and microbial interactions hinder efficacy. This figure highlights innovative strategies—mucoadhesive materials, enzyme inhibitors, and permeation enhancers—to overcome these barriers.

Biomimetic Nanomedicines Deliver Naringin for Enhanced Acute Liver Failure Therapy via Balanced Regulation of Hepatocyte Oxidative Stress and Kupffer Cell Inflammation

Advanced Functional Materials, EarlyView.
A biomimetic nanomedicine (RBLN) constructed by loading natural antioxidants to clinically used layered double hydroxide nanoparticles is surface coated with fresh or senescent red blood cell membrane for balanced drug delivery to hepatocytes and KCs, thereby simultaneously alleviating liver oxidant stress and inflammation for effective drug‐induced ...

Nail bed defect reconstruction using a thenar fascial flap and subsequent nail bed grafting

Archives of Plastic Surgery, 2019
Background Full-thickness nail bed defects with significant exposure of the distal phalanx are typically challenging to reconstruct. We describe a novel method of nail bed defect reconstruction using a thenar fascial flap combined with nail bed grafting.

Voice-controlled Debugging of Spreadsheets [PDF]

Proc. European Spreadsheet Risks Int. Grp. (EuSpRIG) 2007 155-164 ISBN 978-905617-58-6, 2008
Developments in Mobile Computing are putting pressure on the software industry to research new modes of interaction that do not rely on the traditional keyboard and mouse combination. Computer users suffering from Repetitive Strain Injury also seek an alternative to keyboard and mouse devices to reduce suffering in wrist and finger joints.

Radially Interrupted Viscous Fingers in a Lifting Hele-Shaw Cell [PDF]

, 2003
Viscous fingers have been produced in the lifting Hele-Shaw cell, with concentric circular grooves etched onto the lower plate. The invading fluid (air) enters the defending newtonian fluid - olive oil as fingers proceeding radially inwards towards the centre. The fingers are interrupted at the circular groove, and reform as secondary fingers.

Versatile Green Transfer of Magnetoelectronics with Loss‐Free Performance and High Adhesion for Interactive Electronics

Advanced Functional Materials, EarlyView.
An environmentally friendly transfer printing method of nm‐thick giant magnetoresistive (GMR) sensors is demonstrated. This method, relying on water and biocompatible polyvinyl alcohol (PVA) polymer without the need of complex treatments, allows transferring thin films to a wide range of biological, organic, and inorganic substrates.
