It is essential in combat sports such as boxing for athletes to perceive the relevant visual information that enables them to anticipate and respond to their opponent's attacking and defensive moves. Here, we used virtual reality (VR), which enables standardization and reproducibility while maintaining perception-action coupling, to assess the influence of a gaze-contingent blur on the visual processes that underpin these boxing behaviours. Eleven elite French boxers were placed in an immersive and adaptive first-person VR environment where they had to avoid by dodging one or two punches, and then counterattack to strike their opponent.

High quality research is critical for evidence-based decision making in public health and fundamental to maintain progress and trust in immunization programs in Europe. In 2024 the European Centre for Disease Prevention and Control (ECDC) conducted an update of the 2020 systematic review to capture more recent evidence on of the efficacy, effectiveness of influenza vaccines in individuals aged 18 years and older in the prevention of laboratory-confirmed influenza. While this report was highly anticipated due to the strength of the protocol and processes put in place, during our assessment, we expressed two chief concerns.

In the binuclear title complex, [La(CHO)(CHN)(HO)](NO)·0.5HO, the two lanthanum ions are nine coordinate in a distorted trigonal-prismatic geometry. Each La ion is bonded to three N atoms of the Schiff base, 1-(pyridin-2-yl)-2-(pyridin-2-yl-methyl-ene)hydrazine and is coordinated by one acetate group, which acts in -bidentate mode and two acetate groups that act in -mode between the two La ions.

A new hydrated crystalline form of -[()-(4-hy-droxy-phen-yl)methyl-idene]-1-1,2,4-triazol-3-amine and its anti-fungal activity.

Acta Crystallogr E Crystallogr Commun

January 2025

Synchrotron SOLEIL, L'Orme des Merisiers, BP48, Saint Aubin, 91192, Gif-sur-Yvette, France.

The synthesis, crystal structure, Hirshfeld analysis, and anti-fungal assessment of a new monohydrated Schiff base with a triazole moiety are reported. The structural study revealed the presence of three significant hydrogen bonds (N-H⋯N, O-H⋯N, and O-H⋯O), which contribute to the cohesion of the crystal. These bonds generate two-dimensional layers parallel to the plane, built on the basis of rings with the graph-set motifs (8) and (24).

We develop a novel method for image segmentation of 3D confocal microscopy images of emerging hematopoietic stem cells. The method is based on the theory of persistent homology and uses an optimal threshold to select the most persistent cycles in the persistence diagram. This enables the segmentation of the image's most contrasted and representative shapes.

Self-supervised representation learning (SSRL) in computer vision relies heavily on simple image transformations such as random rotation, crops, or illumination to learn meaningful and invariant features. Despite acknowledged importance, there is a lack of comprehensive exploration of the impact of transformation choice in the literature. Our study delves into this relationship, specifically focusing on microscopy imaging with subtle cell phenotype differences.

Deep-blur: Blind identification and deblurring with convolutional neural networks.

Biol Imaging

November 2024

Institut de Recherche en Informatique de Toulouse (IRIT), CNRS & Université de Toulouse, Toulouse, France.

We propose a neural network architecture and a training procedure to estimate blurring operators and deblur images from a single degraded image. Our key assumption is that the forward operators can be parameterized by a low-dimensional vector. The models we consider include a description of the point spread function with Zernike polynomials in the pupil plane or product-convolution expansions, which incorporate space-varying operators.

The clinical efficacy of isocitrate dehydrogenase (IDH) inhibitors in the treatment of patients with grade 2 IDH-mutant (mIDH) gliomas is a significant therapeutic advancement in neuro-oncology. It expands treatment options beyond traditional radiation therapy and cytotoxic chemotherapy, which may lead to significant long-term neurotoxic effects while extending patient survival. The INDIGO study demonstrated that vorasidenib, a pan-mIDH inhibitor, improved progression-free survival for patients with grade 2 mIDH gliomas following surgical resection or biopsy compared to placebo and was well tolerated.

The isocitrate dehydrogenase (IDH) inhibitor, vorasidenib, may offer a promising new treatment option for patients with IDH-mutant gliomas. However, the indefinite nature of this targeted therapy raises significant financial concerns. High costs of targeted cancer therapies, often exceeding $150 000 annually, contribute to financial toxicity, characterized by medical debt, income loss, and psychological stress, and place stress on health systems.

Selection can favor a recombination landscape that limits polygenic adaptation.

Mol Biol Evol

January 2025

Institut de Biologie, École Normale Supérieure, CNRS UMR 8197, Inserm U1024, PSL Research University, Paris, F-75005, France.

Modifiers of recombination rates have been described but the selective pressures acting on them and their effect on adaptation to novel environments remain unclear. We performed experimental evolution in the nematode Caenorhabditis elegans using alternative rec-1 alleles modifying the position of meiotic crossovers along chromosomes without detectable direct fitness effects. We show that adaptation to a novel environment is impaired by the allele that decreases recombination rates in the genomic regions containing fitness variation.
