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.

为了研究NH_(3)-CH_(4)掺混燃气的燃烧特性,设计了一个可视化的旋流湍流燃烧装置,通过实验对当量比(Ф)、氨气掺混比(X_(NH_(3)))和入口空气流量对燃烧特性的影响进行分析。结果表明:随着当量比增加,燃烧室出口NO排放先增加后减小,在Ф=0.9时达到峰值,对其反应速率和燃烧光谱进行分析,发现NO_(2)和HNO浓度协同影响了NO的反应速率,NO排放和OH基强度呈正相关,NH_(2α)基和H_(2)O蒸气产生的链式反应促进了NO的还原。随着X_(NH_(3))升高,火焰由蓝色逐渐转变为橙黄色,NO排放先增加后减少,在X_(NH_(3))=0.4附近出现峰值。另外,随着入口空气流量的增加,气流速度增大导致湍流强度增大,贫燃状态下NO排放增加,而在富燃状态下排放减少,文中对其中机理进行了分析。

Advances in Reproductive Sciences 2024年第2期12卷 83-97页

作者： Melida Aguilar Chamorro Sergio antonio Vargas Collado David Marquez Soriano Clinica Seniors Managua Nicaragua Scientific Department Catalysis S.L. Madrid Spain

Background: Infertility affects 8% - 12% of couples globally, with approximately half of the cases reported in males. Oxidative stress is a common factor increased in the varicocele condition and particularly affects spermatozoa, due to their sensitivity to oxidative signals and testicular hypotrophy. The objective of this clinical trial is to study the effectiveness of Spermotrend in the improvement of sperm parameters in male infertility. Methods: A total of 170 males aged > 18 years with a diagnosis of infertility and varicocele were consecutively enrolled in a Phase II, open-label clinical trial. Spermotrend was administered 1 capsule (450 mg) orally every 8 hours for 6 months and was evaluated through semen analysis at 4 and 6 months of follow-up. Results: The trial results show a significant improvement following the administration of Spermotrend over 6 months in sperm concentration (44.1% at baseline vs. 64.1% at 6 months), sperm survival (28.2% with sperm survival ≥ 2 hours vs.56.5%), normalization of sperm morphology (31.2% vs. 72.9%). Varicocele condition decreased in all patients and, by the end of the study, 55.3% of patients had normal venous flow and dilation. Only 5.9% of the patients showed grade 2 varicocele at the end of the study, while 38.8% showed grade 1 varicocele, with no patients showing grade 3 varicocele. Regarding testicular hypotrophy, 90.6% of the patients completed the study with normalized testicular volume by recovering normal venous flow. Conclusion: A short-term course of Spermotrend may significantly improve sperm parameters associated with male infertility. Clinical Trial Registration: The clinical trial protocol was registered in the international clinical trial registry, ***, with the code: NCT05222841 on 15/06/2021.
