    Iron participates in myriad processes necessary to sustain life. During the past decades, great efforts have been made to understand iron regulation and function in health and disease. Indeed, iron is associated with both physiological (e.g., immune cell biology and function and hematopoiesis) and pathological (e.g., inflammatory and infectious diseases, ferroptosis and ferritinophagy) processes, yet few studies have addressed the potential functional link between iron, the aforementioned processes and extramedullary hematopoiesis, despite the obvious benefits that this could bring to clinical practice. Further investigation in this direction will shape the future development of individualized treatments for iron-linked diseases and chronic inflammatory disorders, including extramedullary hematopoiesis, metabolic syndrome, cardiovascular diseases and cancer.Work in the authors laboratory is supported by: Ministerio de Economía, Industria y Competitividad/Agencia Estatal de Investigacion ´ 10.13039/501100011033 (PID2019-108977RB-I00 and PID2020- 113238RB-I00), Centro de Investigacion Biomédica en Red en Enfermedades Cardiovasculares (CB16/11/00222), Consorcio de Investigacion en Red de la Comunidad de Madrid, S2017/BMD-3686 and Fondo Europeo de Desarrollo Regiona

    Costs of breeding are rapidly buffered and do not affect migratory behaviour in a long-lived bird species

    Life history theory states that individual fitness in one stage of life is conditioned by what occurred in previous stages. In migratory species, reproductive effort during breeding has often been found to influence body condition, molt schedule, self‐provisioning and migration of individuals in subsequent seasons (i.e., carryover effects of breeding). However, there is a current uncertainty in understanding how long‐distance migrants trade off among such energy‐demanding activities (i.e., breeding, molting and migrating). To provide evidence to the field, we experimentally reduced the parental effort of a long‐lived Procellariform, the Cory's shearwater (Calonectris borealis), by inducing failure at the incubation stage. Treatment and control birds were tracked during their subsequent migration by means of light‐level and immersion loggers and sampled for six specific feathers (molted at different periods along the migratory cycle) upon the recovery of the loggers 1 yr later. Feathers were used to perform stable isotope analysis (SIA) and determine corticosterone levels (CORT). By these means, we evaluated the effect of breeding effort on migratory strategy, at‐sea activity patterns, molt patterns, and levels of stress experienced by birds along the non‐breeding period. We did not detect any difference between birds in the induced failure group and successful breeders in terms of spatio‐temporal distribution: all birds shared common foraging areas throughout the study period and the timing of major phenological events did not differ. Failed birds significantly advanced their molt, as revealed by SIA and flying activity patterns. The stress levels of failed birds, inferred through CORT concentrations in feathers, were found to be consistently lower than in successful breeders, through the end of the breeding to the non‐breeding period. Thus, we provide robust evidence that the costs of reproduction can be physiologically mediated from the breeding to the non‐breeding period through molting schedules and CORT levels. However, we failed to detect clear effects on migratory behavior or subsequent breeding success, suggesting that costs of breeding in long‐lived species may be rapidly buffered during the post‐breeding period, as would be expected from life history theory

    Some contributions to the study of oenological lactic acid bacteria through their interaction with polyphenols

    Probiotic features and the ability of two oenological lactic acid bacteria strains (Pediococcus pentosaceus CIAL‐86 and Lactobacillus plantarum CIAL‐121) and a reference probiotic strain (Lactobacillus plantarum CLC 17) to metabolize wine polyphenols are examined. After summarizing previous results regarding their resistance to lysozyme, gastric juice and bile salts, the three strains were assessed for their ability to release phenolic metabolites after their incubation with a wine phenolic extract. Neither of the two bacteria were able to metabolize wine polyphenols, at least in the conditions used in this study, although a certain stimulatory effect on bacterial growth was observed in the presence of a wine‐derived phenolic metabolite (i.e., 3,4‐dihydroxyphenylacetic acid) and a wine phenolic compound (i.e., (+) ‐catechin). Bacteria cell‐free supernatants from the three strains delayed and inhibited almost completely the growth of the pathogen E. coli CIAL‐153, probably due to the presence of organic acids derived from the bacterial metabolism of carbohydrates. Lastly, the three strains showed a high percentage of adhesion to intestinal cells, and pre‐incubation of Caco‐2 cells with bacteria strains prior to the addition of E. coli CIAL‐153 produced a notable inhibition of the adhesion of E. coli to the intestinal cells.The study was supported by the projects AGL2012-40172-C02-01 and AGL2015-64522-C2-1-R of the Spanish Ministry of Economy and Competitiveness (MINECO) and ALIBIRD S2013/ABI-2728 of the Comunidad de Madrid, as well as COST Action POSITIVe FA1403.

    Creación y desarrollo de la marca Casa Casera

    Get PDF
    Esta empresa surge en el 2022, cuando durante un viaje familiar cerca de Michoacán, descubrí a una señora ya mayor de edad vendiendo papas cocidas preparadas consalsa de aceite, la cual resultó ser la mejor salsa que había probado en la vida y con un sabor perfecto para acompañar otras comidas. Por lo cual me surgió la idea de intentar obtener ese sabor en una salsa propia. Hice prueba tras prueba hasta que se logró la receta que hoy en día se utiliza para la salsa. El principal problema detectado en la empresa es que la salsa solo es conocida por un pequeño segmento del mercado, entre ellos familia y amigos. Por el momento Casa Casera ha decidido salir al mercado y ampliar su segmento y distribución. Por lo que la creación de sus redes sociales y relaciones estratégicas ayudará a la marca a pasar de ser esta salsa completamente desconocida para el mercado de Guadalajara, a una salsa conocida por un segmento más amplio.ITESO, A.C
