Abstract
Obesity and diabetes are major risk factors for cardiovascular diseases. Zucker fatty diabetes mellitus (ZFDM) rats are novel animal model of obesity and type 2 diabetes. We have recently reported that blood pressure in ZFDM-Leprfa/fa (Homo) rats was normal, while blood adrenaline level and heart rate were lower than those in control ZFDM-Leprfa/+ (Hetero) rats. Here, we compared the reactivity in isolated mesenteric artery between Hetero and Homo rats. Contraction induced by phenylephrine was increased, while relaxation induced by isoprenaline was decreased in Homo rats at 21-23 weeks old compared with those in Hetero rats. The mRNA expression for α1A but not β2 adrenoreceptor in Homo rats was increased. Nitric oxide (NO)-mediated relaxation induced by acetylcholine was decreased, while the mRNA expression for endothelial NO synthase (eNOS) was rather increased in mesenteric artery from Homo rats. These findings for the first time revealed that in Homo rats with reduced plasma adrenaline, blood pressure could be maintained by enhancing vascular contractility induced by adrenaline through the increased α1 adrenoceptor expression and the attenuated β2 adrenoceptor signaling. Additionally, NO-mediated endothelium-dependent relaxation is impaired perhaps due to eNOS dysfunction, which might also contribute to maintain the blood pressure in Homo rats.

Yang J, He J, Jia L, Gu H. Integrating metagenomics and metabolomics to study the response of microbiota in black soil degradation. THE SCIENCE OF THE TOTAL ENVIRONMENT 2023; 899:165486. [PMID: 37442461 DOI: 10.1016/j.scitotenv.2023.165486] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/10/2023] [Revised: 07/10/2023] [Accepted: 07/10/2023] [Indexed: 07/15/2023]
Abstract
As the largest commercial food production base and ecological security barrier, land degradation in black soil areas seriously threatens the global food supply and natural ecosystems. Therefore, determining the response of soil microbiota is crucial to restoring degraded soils. This study combined metagenomics and metabolomics to investigate the effect of different degrees of soil degradation on microbial community composition and metabolic function in black soils. It was found that alpha diversity in degraded soils (Shannon: 22.3) was higher than in nondegraded soil (ND) (Shannon: 21.8), and the degree of degradation significantly altered the structure and composition of soil microbial communities. The results of LEfSe analysis obtained 9 (ND), 7 (lightly degraded, LD), 10 (moderately degraded, MD), and 1 (severely degraded, SD) biomarkers in four samples. Bradyrhizobium, Sphingomonas, and Ramlibacter were significantly affected by soil degradation and can be considered biomarkers of ND, MD, and SD, respectively. Soil nutrient and enzyme activities decreased significantly with increasing black soil degradation, soil organic matter (SOM) content decreased from 11.12 % to 1.97 %, and Sucrase decreased from 23.53 to 6.59 mg/g/d. In addition, C was the critical driver affecting microbial community structure, contributing 61.2 % to differences in microbial community distribution, and microbial altering relative abundance which participle in the carbon cycle to respond to soil degradation. Metabolomic analyses indicated that soil degradation significantly modified the soil metabolite spectrum, and the metabolic functions of most microorganisms responding to soil degradation were adversely affected. The combined multi-omics analysis further indicated that biomarkers dominate in accumulating metabolites. These findings confirmed that due to their role in the composition and functioning of these degraded soils, these biomarkers could be employed in strategies for managing and restoring degraded black soils.

Abstract
The effects of binary probiotics (Lacticaseibacillus casei CGMCC1.5956 and Lactiplantibacillus plantarum subsp. plantarum CGMCC 1.5953) in conjunction with wolfberry dietary fiber (WDF) on yogurt quality were investigated in this study. d-fructose, β-d-glucose, 6-acetyl-d-glucose, and 1-ketose in WDF significantly improved syneresis, apparent viscosity, and elastic behavior of yogurt. Binary probiotics were more suitable for fermenting WDF yogurt than single probiotics, resulting in a higher viable count (9.39 lg (CFU/mL)) and unique flavor. Binary probiotics can promote the production of tyrosol by L. casei 56 through the tyrosine metabolic pathway, thereby enhancing the resistance of L. casei 56 and L. plantarum 53 to their environment and promoting growth. Pyridine, 2,3,4,5-tetrahydro- and prenol might be responsible for the high odor scores in the sensory evaluation of WDF yogurt prepared using binary probiotics. In summary, combining binary probiotics and WDF can significantly improve yogurt quality and add value to the final product.

Abstract
BACKGROUND Ulcerative colitis involves an excessive immune response to intestinal bacteria. Whether administering prebiotic 1-kestose is effective for active ulcerative colitis remains controversial. AIMS This randomised, double-blind, placebo-controlled pilot trial investigated the efficacy of 1-kestose against active ulcerative colitis. METHODS Forty patients with mild to moderate active ulcerative colitis were randomly treated with 1-kestose (N = 20) or placebo (maltose, N = 20) orally for 8 weeks in addition to the standard treatment. The Lichtiger clinical activity index and Ulcerative Colitis Endoscopic Index of Severity were determined. Faecal samples were analysed to evaluate the gut microbiome and metabolites. RESULTS The clinical activity index at week 8 was significantly lower in the 1-kestose group than in the placebo group (3.8 ± 2.7 vs. 5.6 ± 2.1, p = 0.026). Clinical remission and response rates were higher in the 1-kestose group than in the placebo group (remission: 55% vs. 20%, p = 0.048; response: 60% vs. 25%, p = 0.054). The Ulcerative Colitis Endoscopic Index of Severity at week 8 was not significantly different (2.8 ± 1.6 vs. 3.5 ± 1.6, p = 0.145). Faecal analysis showed significantly reduced alpha-diversity in the 1-kestose group, with a decreased relative abundance of several bacteria, including Ruminococcus gnavus group. The short-chain fatty acid levels were not significantly different between the groups. The incidence of adverse events was comparable between the groups. DISCUSSION Oral 1-kestose is well tolerated and provides clinical improvement for patients with mild to moderate ulcerative colitis through modulation of the gut microbiome.

Supplementation of 1-Kestose Modulates the Gut Microbiota Composition to Ameliorate Glucose Metabolism in Obesity-Prone Hosts. Nutrients 2021; 13:nu13092983.

Abstract
Insulin resistance leads to the onset of medical conditions such as type 2 diabetes, and its development is associated with the alteration in the gut microbiota. Although it has been demonstrated that supplementation with prebiotics modulates the gut microbiota, limited evidence is available for effects of prebiotics on insulin resistance, especially for humans. We investigated the prebiotic effect of 1-kestose supplementation on fasting insulin concentration in obesity-prone humans and rats. In the preliminary study using rats, the hyperinsulinemia induced by high-fat diet was suppressed by intake of water with 2% (w/v) 1-kestose. In the clinical study using obese-prone volunteers, the fasting serum insulin level was significantly reduced from 6.5 µU/mL (95% CI, 5.5–7.6) to 5.3 (4.6–6.0) by the 12-week intervention with supplementation of 10 g 1-kestose/day, whereas it was not changed by the intervention with placebo (6.2 µU/mL (5.4–7.1) and 6.5 (5.5–7.6) before and after intervention, respectively). The relative abundance of fecal Bifidobacterium was significantly increased to 0.3244 (SD, 0.1526) in 1-kestose-supplemented participants compared to that in control participants (0.1971 (0.1158)). These results suggest that prebiotic intervention using 1–kestose may potentially ameliorate insulin resistance in overweight humans via the modulation of the gut microbiota. UMIN 000028824.

Abstract
Diabetes is characterized as an integrated condition of dysregulated metabolism across multiple tissues, with well-established consequences on the cardiovascular system. Recent advances in precision phenotyping in biofluids and tissues in large human observational and interventional studies have afforded a unique opportunity to translate seminal findings in models and cellular systems to patients at risk for diabetes and its complications. Specifically, techniques to assay metabolites, proteins, and transcripts, alongside more recent assessment of the gut microbiome, underscore the complexity of diabetes in patients, suggesting avenues for precision phenotyping of risk, response to intervention, and potentially novel therapies. In addition, the influence of external factors and inputs (eg, activity, diet, medical therapies) on each domain of molecular characterization has gained prominence toward better understanding their role in prevention. Here, the authors provide a broad overview of the role of several of these molecular domains in human translational investigation in diabetes.

Abstract
Sarcopenia causes functional disorders and decreases the quality of life. Thus, it has
attracted substantial attention in the aging modern world. Dysbiosis of the intestinal
microbiota is associated with sarcopenia; however, it remains unclear whether prebiotics
change the microbiota composition and result in the subsequent recovery of muscle atrophy
in elderly patients with sarcopenia. This study aimed to assess the effects of prebiotics
in super-elderly patients with sarcopenia. We analyzed the effects of 1-kestose on the
changes in the intestinal microbiota and body composition using a next-generation
sequencer and a multi-frequency bioimpedance analysis device. The Bifidobacterium
longum population was significantly increased in the intestine after 1-kestose
administration. In addition, in all six patients after 12 weeks of 1-kestose
administration, the skeletal muscle mass index was greater, and the body fat percentage
was lower. This is the first study to show that administration of a prebiotic increased
the population of B. longum in the intestinal microbiota and caused
recovery of muscle atrophy in super-elderly patients with sarcopenia.
