Effect of strain rate on the yielding mechanism of amorphous metal foam [PDF]

open access: yes, 2010
Stochastic amorphous Pd_(43)Ni_(10)Cu_(27)P_(20) foams were tested in quasistatic and dynamic loading. The strength/porosity relations show distinct slopes for the two loading conditions, suggesting a strain-rate-induced change in the foam yielding ...

Mesna in Otologic Surgery: Efficacy and Safety—A Scoping Review

open access: yesThe Laryngoscope, EarlyView.
PRISMA flow diagram indicating the process of systematic inclusion and exclusion of articles. ABSTRACT Objective Mesna (Sodium 2‐mercaptoethanesulfonate) is widely used as a mucolytic agent and uroprotective agent. Recently, its disulfide bond‐breaking property has been applied in otologic surgery to facilitate safer dissection of cholesteatoma and ...

No increased risk of spinal cerebrospinal fluid leak after spinal manipulative therapy: A retrospective cohort study

open access: yesPM&R, EarlyView.
Abstract Background Spinal cerebrospinal fluid (CSF) leaks, a rare but debilitating condition, have been described following spinal manipulative therapy (SMT) in case reports. However, the nature of the potential association between SMT and CSF leak is uncertain, and symptoms such as neck pain or headache may reflect preexisting leaks rather than ...

Spatiotemporal Co‐Delivery of Hydrogen and Magnesium via Microneedle Patches for Neuroinflammation Modulation After Spinal Cord Injury: A Multi‐Modal In Vivo Study

open access: yesSmall, EarlyView.
A spatiotemporal co‐delivery microneedle system (MN‐Mg) is developed for spinal cord injury repair. By generating hydrogen gas and magnesium ions in situ, this dual‐engine platform effectively scavenges ROS and modulates microglial polarization via the MAPK/AP‐1 signaling axis.

Infection control in the brain and the eye

open access: yesActa Ophthalmologica, EarlyView.
Abstract The Central Nervous System (CNS), comprising the brain and the eye, is considered to have a ‘privileged’ mechanism for dealing with immunological challenge (immune privilege, IP). CNS IP has been revealed through experiments using foreign protein antigens and cell and tissue alloantigens (grafts), but evidence for a role for IP in modulating ...

Dynamic Active Constraints for Surgical Robots using Vector Field Inequalities

open access: yes, 2019
Robotic assistance allows surgeons to perform dexterous and tremor-free procedures, but robotic aid is still underrepresented in procedures with constrained workspaces, such as deep brain neurosurgery and endonasal surgery.

A computer-based simulation of vacuum extraction during childbirth [PDF]

open access: yes, 2014
Vacuum extraction is an instrumental method used in obstetrics when childbirth labour fails to progress. The instrument used during vacuum extraction is the ventouse. It comprises of a suction cup attached to the fetal scalp through a vacuum, and a chord

Activation of peripheral NOP receptors reduces periorbital mechanical allodynia evoked by CGRP in mice

open access: yesBritish Journal of Pharmacology, EarlyView.
Background and Purpose Migraine is a neurovascular disorder largely mediated by calcitonin gene‐related peptide (CGRP). This study explores the role of the nociceptin/orphanin FQ (N/OFQ)–N/OFQ receptor (NOP) system in CGRP‐induced periorbital mechanical allodynia (PMA) in mice.
