Objective: To analyze compliance with the current European and Spanish nutritional objectives in a representative sample from Catalonia, a Spanish Mediterranean region; and to examine relationships between diet and plasma fatty acid composition.
Design: Cross-sectional nutritional survey.
Setting: Population based random sample derived from the Catalan Nutrition Survey.
Subjects: A total of 516 healthy adult men (n=203) and women (n=313).
Methods: Dietary habits were assessed by means of a quantitative food frequency questionnaire. A physical exam included height, weight, waist and hip circumferences, and a fasting blood draw.
Results: Gender differences were observed in nutrient and energy intakes. Women showed a better compliance with the nutritional recommendations for monounsaturated fatty acid (MUFA) and polyunsaturated fatty acid (PUFA) than did men. Men showed a better compliance for saturated fatty acid (SFA) and carbohydrate than did women. However, the SFA:MUFA:PUFA ratio was similar in both gender (1.6:2.3:1.0 for men; 1.7:2.5:1.0 for women). The highest compliance was observed for nutritional goals of sodium, calcium and fruit and vegetable intakes for both genders. In addition, the present study showed that levels of certain fatty acids in plasma are clearly associated with dietary intake of foods rich in these components. The highest correlations were found for n-3 long chain polyunsaturated fatty acids with blue fish intake in both men and women (r (men)=0.36 and r (women)=0.42; P<0.001).
Conclusions: The diet followed in Catalonia seems to ensure compliance with most of the intermediate nutritional objectives for the Spanish population. However, a reduction in the SFA intake and an increase in the carbohydrate intake could be recommended in order to reduce the current prevalence of overweight and obesity in this Mediterranean region.
Sponsorship: This study was supported by the Catalan Department of Health, the Nutrition Catalan Centre of the Institute of Catalan Studies, and Mercadona SA.

Increasing evidence implicates disruptions in testicular fatty acid metabolism as a contributing factor in non-obstructive azoospermia (NOA), a severe form of male infertility. However, the precise mechanisms linking fatty acid metabolism to NOA pathogenesis have not yet been fully elucidated. Multi-omics analyses, including microarray analysis, single-cell RNA sequencing (scRNA-seq), and metabolomics, were utilized to investigate disruptions in fatty acid metabolism associated with NOA using data from public databases.

The intestinal microbiota influences many host biological processes, including metabolism, intestinal barrier functions, and immune responses in the gut and distant organs. Alterations in its composition have been associated with the development of inflammatory disorders and cardiovascular diseases, including Kawasaki disease (KD). KD is an acute pediatric vasculitis of unknown etiology and the leading cause of acquired heart disease in children in the United States.

Introduction: Mycophenolate mofetil (MMF) is an immunosuppressive drug administered in the management of both autoimmune diseases and organ transplantation. The main aims of the study were: (a) to obtain information regarding the safety of using MMF in respect of its effect on normal T and B cells in lymphoid tissues; (b) to investigate whether the generation of inducible Foxp3-expressing regulatory T cells (Treg) might constitute additional mechanisms underlying the immunosuppressive properties of MMF.
Methods: The effect of MMF ( studies) and its active metabolite, mycophenolic acid, ( studies) on murine CD4 and CD8 T cells as well as B cells was determined, regarding: (a) absolute count, proliferation and apoptosis of these cells ( studies); (b) absolute count of these cells in the head and neck lymph nodes, mesenteric lymph nodes and the spleen ( studies).
Background: Short-chain fatty acids (SCFAs), derived from the fermentation of dietary fiber by intestinal commensal bacteria, have demonstrated protective effects against acute lung injury (ALI) in animal models. However, the findings have shown variability across different studies. It is necessary to conduct a comprehensive evaluation of the efficacy of these treatments and their consistency.

This study investigates the dynamics of oleate hydratase (OhyA), a bacterial flavoenzyme from , and its interactions with lipid membranes, focusing on the factors influencing membrane binding and oligomerization. OhyA catalyzes the hydration of unsaturated fatty acids, playing a key role in bacterial pathogenesis by neutralizing host antimicrobial fatty acids. OhyA binds the membrane bilayer to access membrane-embedded substrates for catalysis, and structural studies have revealed that OhyA forms oligomers on membrane surfaces, stabilized by both protein-protein and protein-lipid interactions.
