Damage due to ice crystallization.

The freezing of water is one of the major causes of mechanical damage in materials during wintertime; surprisingly this happens even in situations where water only partially saturates the material so that the ice has room to grow. Here we perform freezing experiments in cylindrical glass vials of various sizes and wettability properties, using a dye that exclusively colors the liquid phase; this allows precise observation of the freezing front. The visualization reveals that damage occurs in partially water-saturated media when a closed liquid inclusion forms within the ice due to the freezing of the air/water meniscus.

Cross-species comparison reveals that Hmga1 reduces H3K27me3 levels to promote cardiomyocyte proliferation and cardiac regeneration.

In contrast to adult mammalian hearts, the adult zebrafish heart efficiently replaces cardiomyocytes lost after injury. Here we reveal shared and species-specific injury response pathways and a correlation between Hmga1, an architectural non-histone protein, and regenerative capacity, as Hmga1 is required and sufficient to induce cardiomyocyte proliferation and required for heart regeneration. In addition, Hmga1 was shown to reactivate developmentally silenced genes, likely through modulation of H3K27me3 levels, poising them for a pro-regenerative gene program.

Tralokinumab Treatment in Adult Atopic Dermatitis Patients: 28-Week Evaluation of Clinical Effectiveness, Safety, Serum Proteins and Total IgE Levels.

Introduction And Objectives: Tralokinumab-a biological that specifically targets interleukin-13-is one of the newer advanced systemic treatments for patients with moderate-to-severe atopic dermatitis (AD). Although safety and efficacy have been shown in phase-III clinical trials, daily practice data are needed. Therefore, the aim of this study was to evaluate 28-week safety and effectiveness, serum proteins and total IgE levels in adult AD patients treated with tralokinumab in daily practice.
