This study investigates how recycled metal fibres from End-of-Life Tyres (ELTs) affect both microwave heating efficiency and crack healing properties in dense asphalt mixtures. The aim is to improve tyre recyclability by using their fibres in asphalt and exploring their self-healing potential with microwave heating. To achieve this, four dense asphalt mixture designs were studied in the laboratory.

Erythema nodosum (EN) is a reactive inflammatory panniculitis, which has been associated with medications, infections, autoimmune and autoinflammatory diseases. It has rarely been associated with neoplasms. We present the case of a 61-year old woman who was admitted because 3-week history of painful erythematous subcutaneous nodules on the lower limbs clinically consistent with EN, which was confirmed by skin biopsy.

Brain tumors in children and adults differ greatly in patient outcomes and responses to radiotherapy and chemotherapy. Moreover, the prevalence of recurrent mutations in histones and chromatin regulatory proteins in pediatric and young adult gliomas suggests that the chromatin landscape is rewired to support oncogenic programs. These early somatic mutations dysregulate widespread genomic loci by altering the distribution of histone post-translational modifications (PTMs) and, in consequence, causing changes in chromatin accessibility and in the histone code, leading to gene transcriptional changes.

The majority of primary brain tumors are gliomas, among which glioblastoma multiforme (GBM) is the most common malignant brain tumor in adults. GBM has a median survival of 18-24 months, and despite extensive research it remains incurable, thus novel therapies are urgently needed. The current standard of care is a combination of surgery, radiation, and chemotherapy, but still remains ineffective due to the invasive nature and high recurrence of gliomas.

Article Synopsis
  • - Amyotrophic lateral sclerosis (ALS) is a severe motor neuron disease with about a three-year average survival time, primarily characterized by TDP-43 protein issues that affect gene stability and autophagy processes.
  • - Research on ALS mice revealed that reducing ATG4B worsens survival and autophagy, while an increase in LC3ylation was observed in both ALS patients and mouse models, suggesting a link between these processes.
  • - Antisense oligonucleotides (ASOs) targeting TDP-43 genes have been developed, showing potential for non-invasive treatments that can effectively distribute in the brain after administration.
