Repurposing diacerein for the treatment of chronic wounds in recessive-dystrophic epidermolysis bullosa patients by modulating matrix metalloproteinase-9 expression.

Recessive dystrophic epidermolysis bullosa (RDEB) is caused by mutations in COL7A1, leading to loss or dysfunction of type-VII collagen (C7), a protein essential for skin stability. Clinically, patients suffer from severe skin blistering, chronic or recurrent wounds, and scarring, which predispose to early onset of aggressive squamous cell carcinoma. Previous studies showed that RDEB-keratinocytes (RDEB-KC) express high levels of matrix-metalloproteinase 9 (MMP-9), a molecule known to play a crucial role in wound chronification if dysregulated.

On-Surface Synthesis and Characterization of Pentadecacene and Its Gold Complexes.

Acenes are an important class of polycyclic aromatic hydrocarbons that have gained considerable attention from chemists, physicists, and material scientists, due to their exceptional potential for organic electronics. They serve as an ideal platform for studying the physical and chemical properties of sp carbon frameworks in the one-dimensional limit and also provide a fertile playground to explore magnetism in graphenic nanostructures due to their zigzag edge topology. While higher acenes up to tridecacene have been successfully generated by means of on-surface synthesis, it is imperative to extend their synthesis toward even longer homologues to comprehensively understand the evolution of their electronic ground state.

Beating Cardiac Cell Cultures From Different Developmental Stages of Rainbow Trout as a Novel Approach for Replication of Cardiac Fish Viruses.

Piscine orthoreovirus-1 and 3 (PRV-1, PRV-3) cause highly prevalent infection in cultured salmonids and can induce heart and skeletal muscle inflammation (HSMI) resulting in economic losses in aquaculture. However, to date, PRV-1 and PRV-3 have withstood replication in continuous cell lines. In this study, we used beating heart cell cultures obtained from different developmental stages of rainbow trout (Oncorhynchus mykiss) (RTC-L and RTC-A) and tested their ability to sustain replication of PRV-1 and PRV-3.

Exploring the Nutrition Care Journey of People Living With Obesity in Acute Care.

Background: Recent studies show a high prevalence in hospital populations and best practice evidence indicates that people living with obesity should receive dietetic advice. However, patients often do not receive this care in acute settings. Understanding the experiences of people living with obesity is crucial to designing successful strategies for management.

Impact of sex hormones on pheochromocytomas, paragangliomas, and gastroenteropancreatic neuroendocrine tumors.

Objective: The effects of sex hormones remain largely unexplored in pheochromocytomas and paragangliomas (PPGLs) and gastroenteropancreatic neuroendocrine tumors (GEP-NETs).

Methods: We evaluated the effects of estradiol, progesterone, Dehydroepiandrosterone sulfate (DHEAS), and testosterone on human patient-derived PPGL/GEP-NET primary culture cell viability (n = 38/n = 12), performed next-generation sequencing and immunohistochemical hormone receptor analysis in patient-derived PPGL tumor tissues (n = 36).

Results: In PPGLs, estradiol and progesterone (1 µm) demonstrated overall significant antitumor effects with the strongest efficacy in PPGLs with NF1 (cluster 2) pathogenic variants.
