Background Nursery pigs undergo stressors in the post-weaning period that result in production and welfare *** challenges disproportionately impact the offspring of primiparous sows compared to those of mul-tiparous *** is known regarding potential interactions between parity and feed additives in the post-weaning period and their effects on nursery pig ***,the objective of this study was to investigate the effects of maternal parity on sow and offspring microbiomes and the influence of sow parity on pig fecal microbi-ome and performance in response to a prebiotic *** weaning,piglets were allotted into three treat-ment groups:a standard nursery diet including pharmacological doses of Zn and Cu(Con),a group fed a commercial prebiotic only(Preb)based on an Aspergillus oryzae fermentation extract,and a group fed the same prebiotic plus Zn and Cu(Preb+ZnCu).Results Although there were no differences in vaginal microbiome composition between primiparous and mul-tiparous sows,fecal microbiome composition was different(R^(2)=0.02,P=0.03).The fecal microbiomes of primiparous offspring displayed significantly higher bacterial diversity compared to multiparous offspring at d 0 and d 21 post-weaning(Perences in community composition observed at d 21(R^(2)=0.03,P=0.04).When analyzing the effects of maternal parity within each treatment,only the Preb diet triggered significant microbiome distinc-tions between primiparous and multiparous offspring(d 21:R^(2)=0.13,P=0.01;d 42:R^(2)=0.19,P=0.001).Composi-tional differences in pig fecal microbiomes between treatments were observed only at d 21(R^(2)=0.12,P=0.001).Pigs in the Con group gained significantly more weight throughout the nursery period when compared to those in the Preb+ZnCu *** Nursery pig gut microbiome composition was influenced by supplementation with an Aspergillus oryzae fermentation extract,with varying effects on performance

The thermoluminescence(TL)emission of synthetic and natural Ce-monazites was characterized here to determine the potential application in the identification of microscopic defects from a qualitative point of view trying to link each TL peak to a chemical-physical *** kinetic parameters that lead the luminescence processes were calculated by means of variable heating rate and computing glow curve deconvolution methods and allow identifying three groups of components at~90,130 and 290℃(for the mineral sample)and~90,170,220,270 and 320℃(for the synthetic CePO_(4):Nd_(0.20),La_(0.25)).The main differences appreciated in these complex TL curves are mainly due to(i)the content of impurities(natural sample contains lanthanides as well as U 0.60%and Th 5.22%)and(ii)the degree of crystallinity of the samples which is directly related to the type of impurities(synthetic monazite relies only on Nd and La).The behavior of the dose response in the range of 1-8 Gy is similar for both samples;the TL intensity increases linearly as the dose increases without changes in the position of the maxima,denoting first-order kinetic luminescence *** peak could be mostly associated with structural defects(i.e.,phase transitions),chemical reactions(i.e.,Ce3+?Ce4+redox reaction,dehydration or dehydroxylation processes)or intrinsic defects(i.e.,Frenkel defects,ODCs or NBOHCs).

Fungi Associated with Sand and Plants from Marine Coastlines: Potential Relevance for Human Health

引用

Advances in Microbiology 2024年第6期14卷 303-316页

作者： Marina Carrasco-Acosta Pilar garcia-Jimenez Department of Biology Universidad de Las Palmas de Gran Canaria Campus de Tafira Las Palmas Spain

The fungal community associated with beach sand and plants located along marine coasts are an under-studied area of research despite its potential relevance to human health. In this study, we isolated and identified the cultivable mycobiota associated with sand and plants collected along the coast of Gran Canaria (Spain) using culture-dependent and -independent methods. Clinically relevant species belonging to Cryptococcus spp. and related genera such as Naganishia and Papilotrema were isolated and identified from shoreline plants. Moreover, Candida tropicalis was isolated from beach sand, and Aspergillus fumigatus and Aspergillus terreus strains were associated with both types of samples (i.e., plants and beach sand). We conclude that beach sand and shoreline plants are potential reservoirs of fungi of high clinical interest. We recommend including beach sand and plants from the environment when assessing the quality of marine coastal systems. Our results open a framework for studying the natural marine environment and its role in the epidemiology of infectious diseases in order to more accurately manage public health.

Background: Myocardial ischemia in addition to other several cardiac syndromes represent a pathological proinflammatory state alongside a complex cellular microenvironment that can be modified by using cannabinoids. Cannabidiol (CBD), a non-psychoactive compound of cannabis has been recently proposed as an immudomodulatory and cardioprotective drug. Objectives: In this systematic review we sought to clarify and summarize the clinical and preclinical evidence of potential benefit of the use of CBD in coronary syndromes. Methods: We conducted a systematic search and review according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) and Review of Animal Data from experimental Studies (CAMARADeS) guidelines, in the electronic database from PubMed, Web of Science and Scopus up to April 2022 using predefined search terms. Pre-specified exclusion and inclusion criteria were considered, finally 11 articles were chosen to be included for this peer review. Results: Currently there are no good-quality clinical trials with the use of CBD in acute or chronic coronary syndromes. A total of 11 preclinical studies where prescreened and 5 demonstrated reproducible positive cardiovascular outcomes on in-vivo models treated with CBD. Mechanisms of CBD cardioprotection observed: 1) reduction in oxidative stress and inflammation, 2) activation of adenosine receptors and 3) increased expression of angiotensin type 2-receptor. experimental models included ischemia/reperfusion injury, myocardial infarction, arrhythmias, and metabolic syndrome-like conditions. Conclusion: No clinical recommendation can be issued with the current evidence, on the use of CBD in acute and chronic coronary syndromes. Based on preclinical evidence, we considered there is enough evidence to propose the development of well-designed clinical trials that include CBD in the management of coronary syndromes.

Intestinal anti-inflammatory effect of a plant sterol food supplement in experimental murine colitis and cell co-culture models

引用

Food Science and Human Wellness 2024年

作者： Mussa Makran Antonio Cilla Rosa María Giner María Carmen Recio Luisa Tesoriere Alessandro Attanzio Guadalupe garcia-Llatas Nutrition and Food Science Area， Faculty of Pharmacy and Food Sciences， University of Valencia.Av.Vicente Andrés estellés s/n Department of Pharmacology， Faculty of Pharmacy and Food Sciences， University of Valencia.Av.Vicente Andrés estellés s/n Department of Biological， Chemical and Pharmaceutical Sciences and Technologies， University of Palermo

The potential of a plant sterol food supplement （PS-FS） in addressing intestinal inflammation in vivo and in vitro was evaluated. As in vivo model， C57BL/6J mice were exposed to 1.5% dextran sulfate sodium in three 5-day periods， with 10-day rest intervals in between， daily reciving PS-FS （35 mg PS/kg）. The in vitro approach involved a bi-cameral system with 8-day-differentiated Caco-2 （apical） and RAW264.7 cells （basolateral）. The bioaccessible fraction of PS-FS， obtained after INFOGeST 2.0 simulated gastrointestinal digestion， was added to the apical part （90 min）， followed by stimulation with lipopolysaccharide （1 μg/mL， 24 h）. PS-FS alleviated rectal bleeding and rebalanced pro- (tumor necrosis factor α， interleukin （IL）-6， and IL-8) and anti-inflammatory cytokines （IL-10）. Additionally， PS-FS ameliorated histopathological damage and enhancing occludin expression. A reduction in oxidative stress was evidenced by decreased myeloperoxidase activity and reactive oxygen species production. The anti-inflammatory mechanism included suppressing cyclooxygenase 2 expression， reducing prostaglandin e2production， and inhibiting the phosphorylation and nuclear translocation of the nuclear factor κB p65 subunit. This study reveals the potential of PS-FS as a therapeutic intervention for colitis. The alignment between in vivo and in vitro outcomes substantiates the appropriateness of the co-culture model to evaluate the anti-inflammatory activity of foods.
