Optimization of ciliary body cyclophotocoagulation settings: a randomized and controlled pilot study.

Objective: To compare the efficacy of different settings in continuous-wave transscleral cyclophotocoagulation (CW-TSCPC).

Design: Prospective, randomized, triple-blind clinical trial in a single tertiary center.

Participants: Adult glaucoma patients who need continuous wave-transscleral cyclophotocoagulation to control intraocular pressure (IOP) or prevent or treat ocular pain/discomfort secondary to increased IOP.

The fruits of data shepherding: A collection of open FAIR datasets for titanium dioxide coated photocatalytic surfaces.

This paper presents a large-scale collaborative effort within a multi-partner consortium, to systematically structure, curate, and openly share data in alignment with the FAIR principles. The data result from a case study of titanium dioxide (TiO₂) nanomaterials (NMs) for photocatalytic depolluting surfaces, produced via various spray coating techniques under the Safe and Sustainable by Design (SSbD) approach. The data are publicly available through a dedicated Zenodo community (https://zenodo.

Application of in vitro pulmonary models for hazard screening of silica particles.

There is an increasing need for new approach methodologies (NAMs) for safety assessment of nanomaterials (NMs) in order to keep pace with innovation. In vitro assays are useful tools during pre-market hazard screening approaches of NMs to prioritize safe(r) candidate NMs and reduce the amount of regulatory testing required. For pre-regulatory hazard screening applications, it is crucial that in vitro assays have the capacity to distinguish between NMs based on their hazard potency and have the ability to provide accurate hazard rankings.

Hazard screening of colloidal silica nanomaterials with varying degrees of silane surface functionalization: a safe-by-design case study.

Background: The Safe and Sustainable by Design (SSbD) concept facilitates the design of safer and more sustainable chemicals and materials and is a crucial approach towards reaching the goals set out in the European Green Deal. It is critical that suitable guidance is provided on how to use new approach methodologies (NAMs) to fill hazard data gaps for nanomaterials (NMs) to facilitate SSbD decisions. Here, we showcase a nano-specific in vitro SSbD case study.

In vitro cell-transforming capacity of micro- and nanoplastics derived from 3D-printing waste.

The increasing use of plastic polymers in 3D printing applications may lead to human exposure to micro- and nanoplastics (MNPLs), raising concerns regarding adverse health consequences such as cancer induction. Little attention has been given to MNPLs originated at the end of the life cycle of 3D-printed objects because of the mechanical and environmental degradation of plastic waste. This study assessed the carcinogenic potential of secondary MNPLs generated through cryomilling of 3D objects using the validated in vitro Bhas 42 cell transformation assay (CTA).
