Infection control in the brain and the eye

Acta 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 ...

Collapse resistance assessment of bucklingrestrained braced steel frames using combined deterministic and probability analysis approach [PDF]

, 2019
The load bearing capacity, global ductility and overall stability of steel frame can be improved significantly through the use of buckling-restrained braces (BRBs). Based on the open resource platform OpenSees, finite element models of two types of steel

Proteolytic remodelling of the extracellular matrix by pericytes

The FEBS Journal, EarlyView.
Pericytes are specialised perivascular cells intimately connected with endothelial cells and essential for the maintenance of vascular beds. They contribute to the formation and remodelling of the extracellular matrix by actively secreting proteases and protease inhibitors.

Effect of pre-tensioning force on behavior of Buckling Restrained Brace (BRB) supported by double pre-tensioning system

Fracture and Structural Integrity
The study explores the feasibility of a new all-steel buckling restrained brace (BRB) with the double pre-tensioning system as an alternative to conventional concentrically braced frames by using finite element method (ABAQUS program), And to verify ...

Low‐Cost Friction‐Based Force‐Limiting Connection With Reduced Sensitivity to Machining Tolerances and Accelerated Repairability

Earthquake Engineering &Structural Dynamics, Volume 55, Issue 6, Page 1270-1291, May 2026.
ABSTRACT This paper presents a novel yet practical friction‐based structural component design for low‐damage earthquake‐resistant structures. The proposed connection design is based on a conventional slotted‐bolted configuration with the novelty being the use of loose steel washer plates to establish the friction‐sliding interface.

A Comparison of Ground Motion Intensity Measures for Estimating Collapse

Earthquake Spectra, Volume 42, Issue 2, May 2026.
This study examines the use of 15 different intensity measures (IMs) for estimating structural collapse using results from incremental dynamic analysis (IDA). IDA results from 54 numerical models were considered, including (i) 12 reinforced concrete (RC) frame structures, (ii) 16 RC wall–frame structures and (iii) 26 steel buckling‐restrained braced ...

Numerical comparison on the efficiency of conventional and hybrid buckling-restrained braces for seismic protection of short-to-mid-rise steel buildings [PDF]

, 2019
Buckling-restrained brace (BRB) is a specific kind of bracing system which has an acceptable energy dissipation behavior in a way that would not be buckled in compression forces.

A Cationic Block Co‐Polymer for Gene Delivery in the Posterior Segment of the Eye

Journal of Biomedical Materials Research Part A, Volume 114, Issue 5, May 2026.
ABSTRACT Diseases of the back of the eye such as neovascular age‐related macular degeneration (nAMD) are vision threatening and treatment is burdensome for patients, often requiring ocular injections every other month. Injection risks and logistics lower patient compliance; however, even patients receiving optimal treatment can deteriorate.
