Mindfulness is an increasingly popular practice among elite athletes to improve performance and well-being, but its application for coaches is still very limited. Therefore, a new program (M×E; Mindfulness para Entrenadores) was designed and implemented online for 6 weeks for coaches, support staff, and technical directors. Participants were 58 (57 men), aged between 23 and 58 (M = 31.

Article Synopsis
  • - The research presents a 3-step enzymatic method to convert waste chitin, found in food industry byproducts, into valuable chitooligomers with a degree of polymerization (DP) between 6 to 11.
  • - The process begins with hydrolyzing chitin using engineered fungal chitinase, followed by an extension step using a β--acetylhexosaminidase variant to enhance yields up to 57%.
  • - Finally, chitooligomers with DP 6 and 7 undergo enzymatic deacetylation, resulting in bioactive chitooligomers that could be used as natural pesticides for sustainable agriculture.

Histone deacetylase SIRT1 represses gene expression through the deacetylation of histones and transcription factors and is involved in the protective cell response to stress and aging. However, upon endoplasmic reticulum (ER) stress, SIRT1 impairs the IRE1α branch of the unfolded protein response (UPR) through the inhibition of the transcriptional activity of XBP-1 and SIRT1 deficiency is beneficial under these conditions. We hypothesized that SIRT1 deficiency may unlock the blockade of transcription factors unrelated to the UPR promoting the synthesis of chaperones and improving the stability of immature proteins or triggering the clearance of unfolded proteins.

Through GWAS studies we identified PATJ associated with functional outcome after ischemic stroke (IS). The aim of this study was to determine PATJ role in brain endothelial cells (ECs) in the context of stroke outcome. PATJ expression analyses in patient's blood revealed that: (i) the risk allele of rs76221407 induces higher expression of PATJ, (ii) PATJ is downregulated 24 h after IS, and (iii) its expression is significantly lower in those patients with functional independence, measured at 3 months with the modified Rankin scale ((mRS) ≤2), compared to those patients with marked disability (mRS = 4-5).

Diseases of the central nervous system (CNS) are often associated with vascular disturbances or inflammation and frequently both. Consequently, endothelial cells and macrophages are key cellular players that mediate pathology in many CNS diseases. Macrophages in the brain consist of the CNS-associated macrophages (CAMs) [also referred to as border-associated macrophages (BAMs)] and microglia, both of which are close neighbours or even form direct contacts with endothelial cells in microvessels.
