The prebiotic properties of Hibiscus sabdariffa extract contribute to the beneficial effects in diet-induced obesity in mice

This study evaluates the effects of a chemically characterized polyphenolic extract of H. sabdariffa (HSE) in an experimental model of diet-induced obesity (DIO) in mice. HSE was administered daily by oral gave for 42 days. HSE reduced weight increase in high fat diet (HFD)-fed mice, and improved glucose tolerance, insulin sensitivity and normalized LDL/HDL cholesterol ratio. It also enhanced the inflammatory state in the liver, reducing the expression of different adipokines and proinflammatory mediators, and reinforced gut integrity by increasing the expression of mucins and proteins involved in the maintenance of mucosal barrier. Moreover, HSE had a prebiotic effect, ameliorating the changes in the gut microbiota induced by the HFD. Thus, HSE improved the Firmicutes/Bacteroidetes ratio, which may contribute to the beneficial effects. Consequently, HSE could be considered for the development of a complementary treatment for the metabolic syndrome due to its beneficial properties.Graphical abstract

Discussion/conclusion: A wild-type mouse model of metabolic syndrome fed a "fast food" diet developed changes to the retina similar to some of the pathologic features seen in AMD. Further investigations into this and similar animal models as well as further epidemiological studies are needed to more clearly define the association between metabolic syndrome and AMD.

CONCLUSION: In conclusion, increased IL-1β levels correlate to dyslipidemic factors and may further support low-grade inflammation. IL-1β may further predict the early onset of cardiovascular disease within this population, taking into consideration its important regulatory role. PMID: 31738140 [PubMed - as supplied by publisher]

ÁCC Abstract We determined the prevalence of Metabolic Syndrome (MetS) and associated factors in 419 women (aged 40 to 65 years) in Northeast Brazil in a cross-sectional study conducted from April to November 2013. We defined MetS using the National Cholesterol Education Program Adult Treatment Panel III (NCEP-ATP III) criteria. Socio-demographic variables, reproductive factors, lifestyle factors, anthropometrics, body composition, quality of life, and physical performance were assessed for their associations. We constructed multivariate Poisson regression models to estimate prevalence rate ratios (PRR) and...

We examined the relationship between baseline MetS and renal dysfunction after a 3-year evaluation based on estimated glomerul ar filtration rate (eGFRCKDEPI) using the CKD-EPI equations modified by the Japan coefficient. CKD was defined as dipstick-positive proteinuria (>  or = 1 +) or a low eGFRCKDEPI (

Contributors : Charles A Harris ; Daniel FergusonSeries Type : Expression profiling by high throughput sequencingOrganism : Mus musculusIncreased visceral adiposity and hyperglycemia, two characteristics of metabolic syndrome, are also present in conditions of excess glucocorticoids (GCs). GCs are hormones thought to act primarily via the glucocorticoid receptor (GR). GCs are commonly prescribed for inflammatory disorders, yet their use is limited due to many adverse metabolic side effects. In addition to GR, GCs also bind the mineralocorticoid receptor (MR), but there are many conflicting studies as to the exact role of M...

In this study, we attempted to observe the detailed three-dimensional structure of paramylon by focused ion beam/scanning electron microscopy (FIB/SEM). Paramylon samples were fixed and three-dimensional image reconstruction and segmentation of the image stack were created using computer software (Amira v6.0.1, FEI). The results indicated that the inside of paramylon particles (diameter: 5μm, thickness: 3μm) was comprised of a dense structure with no evidence of the presence of large pores and gaps, although a small 100 nm crack was observed. The specific surface area of paramylon particles measured by the BET method...

ConclusionDietary application of nanoceria combined with probiotic strainsL. casei IMV B-7280,B. animalis VKB, andB. animals VKL has significantly reduced both free and bound cholesterol levels in serum. Simultaneous administration of probiotics and cerium nanoparticles as a prebiotic, in various combinations, significantly enhanced positive individual effects of them on the gut microbiota spectrum. The presented results provide novel insights into mechanisms behind nutritional supplements and open new perspectives for application of probiotics combined with substances demonstrating prebiotic qualities benefiting, therefor...

Metabolic syndrome is characterised by a clustering of metabolic risk factors including abdominal obesity, raised triglycerides, lowered HDL cholesterol, hypertension and impaired glucose tolerance. Multifaceted lifestyle interventions including diet and exercise are recommended as the first-line treatment for the metabolic syndrome.

Cibiček N, Karásek D Abstract Coronary risk evaluation by conventional factors (age, gender, smoking, blood pressure and cholesterol) may further be specified by facets of the metabolic syndrome, namely insulin resistance, hypertriglyceridemia and obesity. Although obesity is usually defined as elevated body mass index (BMI), recent data indicate a superior role of waist circumference or hypertriglyceridemic waist (HTGW) over BMI in the assessment of cardiometabolic risk. In dyslipidemic patients, the specific contributions of risky waist, HTGW or BMI have not been evaluated as yet. 686 dyslipidemic subje...
