Specialized pro-resolving lipid mediators including maresin 1 mediate resolution but the levels of these are reduced in Alzheimer's disease brain, suggesting that they constitute a novel target for the treatment of Alzheimer's disease to prevent/stop inflammation and combat disease pathology. Therefore, it is important to clarify whether they counteract the expression of genes and proteins induced by amyloid-β. With this objective, we analyzed the relevance of human monocyte–derived microglia for in vitro modeling of neuroinflammation and its resolution in the context of Alzheimer's disease and investigated the pro-resolving bioactivity of maresin 1 on amyloid-β42–induced Alzheimer's disease–like inflammation. Analysis of RNA-sequencing data and secreted proteins in supernatants from the monocyte-derived microglia showed that the monocyte-derived microglia resembled Alzheimer's disease–like neuroinflammation in human brain microglia after incubation with amyloid-β42. Maresin 1 restored homeostasis by down-regulating inflammatory pathway related gene expression induced by amyloid-β42 in monocyte-derived microglia, protection of maresin 1 against the effects of amyloid-β42 is mediated by a re-balancing of inflammatory transcriptional networks in which modulation of gene transcription in the nuclear factor-kappa B pathway plays a major part. We pinpointed molecular targets that are associated with both neuroinflammation in Alzheimer's disease and therapeutic targets by maresin 1. In conclusion, monocyte-derived microglia represent a relevant in vitro microglial model for studies on Alzheimer's disease-like inflammation and drug response for individual patients. Maresin 1 ameliorates amyloid-β42–induced changes in several genes of importance in Alzheimer's disease, highlighting its potential as a therapeutic target for Alzheimer's disease.

AIM: To document the concerns and expectations of parents of children with inflammatory bowel disease (IBD)within the context of a multidisciplinary IBD clinic, and to highlight the importance of a holistic approach to the care of these ***: The parents of 60 children with IBD were surveyed by mailed questionnaire. Parents were asked to provide details of their concerns regarding their child's condition and to express their expectations of medical care. In addition, enquiry was made in respect to the respondents' learning about ***: Forty-six questionnaires (77%) returned. Fiftytwo percent of the patients were male. Patients were aged a mean of 10.9 (±4.1) years and diagnosed at an average age of 2.1 (±1.8) years previously. The most common concerns expressed by the parents related to the side- effects of medications and the future prospects for their child. Overall, parents were satisfied with aspects of care within the IBD clinic but many suggested additional personnel such as counselors or educators should be available. Parents also reported the need for continuing education and easy access to up-to-date ***: Parents of children and adolescents with IBD have many common concerns regarding their child's condition. On-going attention to holistic care, including psychosocial and educational elements for patients and families, is appropriate in the context of the chronic and unpredictable nature of IBD.

Effects of tomato juice on the pharmacokinetics of CYP3A4-substrate drugs

引用

Asian Journal of Pharmaceutical Sciences 2017年第5期12卷 464-469页

作者： Atsuko Ohkubo Tomomi Chida Hidetomo Kikuchi Tadashi Tsuda Katsuyoshi Sunaga Laboratory of Pharmacotherapy Department of Clinical Dietetics and Human Nutrition Faculty of Pharmaceutical Sciences Josai University

We previously demonstrated that tomato juice(TJ) contains potent mechanism-based inhibitor(s) of CYP3A4. In this study, we investigated the effects of TJ and grapefruit juice(GFJ)on the pharmacokinetics of the CYP3A4-substrate drugs, nifedipine(NFP) and midazolam(MDZ), in male Wistar rats. Oral administration of GFJ 90 min before the intraduodenal administration of NFP or MDZ increased the area under the concentration–time curves(AUCs)of NFP and MDZ by 32.4% and 89.4%, respectively. TJ increased MDZ blood concentrations and AUC after intraduodenal MDZ administration;however, it had no effect on NFP. When MDZ and NFP were intravenously administered, GFJ significantly increased the AUC of MDZ,but only slightly increased that of NFP. In contrast, TJ only slightly increased the AUC of *** results suggest that, similar to GFJ, TJ influences the pharmacokinetics of CYP3A4-substrate drugs;however, it may be a drug-dependent partial effect.

The effect of caloric restriction on genetical pathways

引用

Food Science and Human Wellness 2023年第5期12卷 1450-1457页

作者： Mustafa Fevzi Karagöz A.Gülçin Sağdıçoğlu Celep Faculty of Health Sciences Department of Nutrition and DieteticsGazi UniversityÇankaya 06490Turkey

Energy restriction is defined as reducing nutrient intake without dragging the organism into malnutrition. Energy restriction is preferred because it is a non-genetic intervention that increases life expectancy. Nicotinamide adenine dinucleotide(NAD~+)and adenosine monophosphate(AMP)levels, which are the indicators of intracellular energy deficiency, increase with energy restriction. The increase in NAD~+ level stimulates sirtuin(SIRT)enzymes, and the increase in AMP level stimulates AMP-activated protein kinase(AMPK). Various mechanisms are regulated by stimulating these enzymes. By Forkhead box O(FoxO)transcription factors, the ability of resistance to oxidative stress increases, and antioxidant genes, DNA repair, and autophagy genes are stimulated. Apoptosis is induced by stimulation of the p53 protein, and tumor growth is suppressed by the disruption of aging cells. The suppression of phosphoinositide 3-kinase(PI3K)-/-Akt, and therefore mTOR signal stimulates autophagy and mitophagia, and cleanses damaged cells and organelles. Mitochondrial biogenesis is stimulated, antioxidant capacity increases, and inflammatory response decreases. Adipose tissue and lipid metabolism are regulated by the regulation of fatty acid synthesis and oxidation. As a consequence, the effects of caloric restriction on cellular metabolism are regulated through the genetic pathways.

AIM:To examine if dietary and socio-economic factors contribute to Helicobacter pylori(H pylori)re-infection. METHODS:The population of patients consisted of subjects in whom H pylori infection had been successfully treated in the *** were divided into two groups:Ⅰ-examined group(111 persons with H pylori re-infection)andⅡ-control group(175 persons who had not been re-infected).The respondents were interviewed retrospectively on their dietary habits and socio-economic factors. RESULTS:A statistically significant lower frequency of fermented dairy products(P<0.0001),vegetables (P=0.02),and fruit(P=0.008)consumption was noted among patients with H pylori re-infection as compared to those who had not been re-infected. CONCLUSION:High dietary intake of probiotic bacteria,mainly Lactobacillus,and antioxidants,mainly vitamin C(contained in fruit and vegetables),might decrease the risk of H pylori re-infection.
