Cardiocirculatory pathophysiological mechanisms in severe acute pancreatitis

World Journal of Gastrointestinal Pharmacology and Therapeutics 2010年第1期1卷 9-14页

作者： mónica garcía José Julián Calvo Department of Physiology and Pharmacology Campus miguel de Unamuno Universidad de Salamanca

Acute pancreatitis (AP) is a common and potentially lethal acute inflammatory process. Although the majority of patients have a mild episode of AP, 10%-20% develop a severe acute pancreatitis (SAP) and suffer systemic inflammatory response syndrome (SIRS) and/or pancreatic necrosis. The main aim of this article is to review the set of events, f irst localized in the pancreas, that lead to pancreatic inflammation and to the spread to other organs contributing to multiorganic shock. The early pathogenic mechanisms in SAP are not completely understood but both premature activation of enzymes inside the pancreas, related to an impaired cytosolic Ca2+ homeostasis, as well as release of pancreatic enzymes into the bloodstream are considered important events in the onset of pancreatitis disease. moreover, afferent f ibers within the pancreas release neurotransmitters in response to tissue damage. The vasodilator effects of these neurotransmitters and the activation of pro-inflammatory substances play a crucial role in amplifying the inflammatory response, which leads to systemic manifestation of AP. Damage extension to other organs leads to SIRS, which is usually associated with cardiocirculatoryphysiology impairment and a hypotensive state. Hypotension is a risk factor for death and is associated with a signif icant hyporesponsiveness to vasoconstrictors. This indicates that stabilization of the patient, once this pathological situation has been established, would be a very diff icult task. Therefore, it seems particularly necessary to understand the pathological mechanisms involved in the f irst phases of AP to avoid damage beyond the pancreas. moreover, efforts must also be directed to identify those patients who are at risk of developing SAP.

Background: Both competitive and recreational sports are considered a positive practice that is good for human health and quality of life, so it is difficult to understand how young, energetic and apparently healthy people can die while playing their usual sports. When these events occur in elite athletes during monitored events, they normally receive considerable media attention. Objective: To describe the case of sudden death in a young professional athlete who was successfully aided and resuscitated outside our hospital, and to review the literature about sudden death in sports. materials and method: We searched for Sudden Death (according to the International Classification of Diseases (ICD-9 and ICD-10)) in our hospital but found no other relevant cases. We performed a literature search on the state of the art in sudden death (Google Scholar, Pubmed, LILACS, Scielo and the Revista Española de Cardiología). Results: Although we observed that the prevalence of sudden death is not very high, it still represents a potentially avoidable event. An adequate medical examination prior to regular sporting practice can decrease the incidence of sudden death in athletes under the age of 35. Data available in the literature support medical check-ups that include history-taking, physical examination and electrocardiogram. The findings of this evaluation may also prompt further assessment (electrocardiograph, ergometry). Conclusions: We could not identify standard, obligatory guidelines for screening possible heart diseases causing cardiorespiratory failure and sudden death. As a measure for primary prevention, we propose a protocol for reducing the risk of sudden death in athletes.

Dendritic spine degeneration:a primary mechanism in the aging process

Recent reports suggest that aging is not solely a physiological process in living beings;instead, it should be considered a pathological process or disease(Amorim et al., 2022). Consequently, this process involves a wide range of factors, spanning from genetic to environmental factors, and even includes the gut microbiome(Gm)(mayer et al., 2022). All these processes coincide at some point in the inflammatory process, oxidative stress, and apoptosis, at different degrees in various organs and systems that constitute a living organism(mayer et al., 2022;AguilarHernández et al., 2023).

Proteomic dynamics revealed sex-biased responses to combined heat-drought stress in marchantia

引用

Journal of Integrative Plant Biology 2024年第10期66卷 2226-2241页

作者： Sara Guerrero Víctor Roces Lara garcía-Campa Luis Valledor mónica meijón Department of Organisms and Systems BiologyFaculty of Biology/BiotechnologyInstitute of AsturiasUniversity of OviedoOviedoAsturias 33071Spain

Recent studies have documented plant responses to climate change extensively, particularly to single-stress exposures. However, critical factors for stress survival, such as sexual differentiation,are not often considered. The dioicous marchantia polymorpha stands as an evolutionary milestone,potentially preserving ancestral traits from the early colonizers. In this study, we employed proteomic analyses complemented with physiological monitoring to investigate combined heat and drought responses in Tak-1(male) and Tak-2(female)accessions of this liverwort. Additionally, targeted transcriptomics was conducted using different natural populations from contrasting *** findings revealed sex-biased dynamics among natural accessions, particularly evident under control conditions and during early stress responses. Although Tak-2 exhibited greater diversity than Tak-1 under control conditions, male accession demonstrated distinct and more rapid stress sensing and signaling. These differences in stress response appeared to be strongly related to sex-specific plasticity influenced by geoclimatic origin. Furthermore, we established distinct protein gene ages and genomic distribution trends, underscoring the importance of protein diversification over time. This study provides an evolutionary perspective on sexual divergence and stress emergence employing a systems biology approach, which allowed for the establishment of global and sex-specific interaction networks in the stress response.
