Optimization of fs-laser-induced voxels in nonlinear materials via over-correction of spherical aberration.

In this Letter, over-correction of spherical aberration is used to counteract nonlinear effects such as Kerr self-focusing and plasma effects, resulting in more spherical and small-sized femtosecond laser-inscribed voxels within nonlinear materials. By strategically redirecting marginal focusing rays toward the beginning of the laser modification zone, the induced plasma prevents any rays from causing a structural modification beyond this zone, irrespective of any focus elongation caused by nonlinear effects. The method has been effectively validated across a range of materials, including ZnS, ZnSe, BIG, GeS, and SiO.

Cross-cultural adaptation and validation of a French version of the perceived personal control questionnaire as an outcome measure instrument for genetic counseling.

The perceived personal control (PPC) questionnaire serves as an instrument to assess the concept of PPC, which refers to a person's perception of their ability to achieve positive outcomes while avoiding the negative effects of a given situation. Developed and used as a patient-reported outcome measure (PROM) in genetic counseling, the PPC questionnaire has been translated and validated in several languages, but not in French. The aim of this study was to cross-culturally adapt and validate a French version of the PPC questionnaire to evaluate genetic counseling services for hereditary breast and ovarian cancer (HBOC).

Preclinical Evaluation of AZD6422, an Armored Chimeric Antigen Receptor T Cell Targeting CLDN18.2 in Gastric, Pancreatic, and Esophageal Cancers.

Purpose: Claudin 18.2 (CLDN18.2) is a surface membrane protein that is crucial for maintaining tight junctions in gastric mucosal cells and is highly expressed in gastric, esophageal, and pancreatic cancers.

Femtosecond laser writing of robust waveguides in optical fibers with enhanced photosensitivity.

We report the femtosecond laser writing of meter-long optical waveguides inscribed through the coating of specifically designed optical fibers. In order to improve the material photosensitivity and to ensure non-guiding optical fibers for subsequent laser processing of the waveguiding core, a depressed refractive index core design is implemented by co-doping a large portion of the optical fiber with germanium oxide and fluorine. The enhanced photosensitivity provided by further deuterium loading these fibers allows laser-writing of large refractive index contrast waveguides over wide cross sections.
