Multifunctional polymersomes loaded with maghemite nanoparticles and grafted an antibody, directed against human endothelial receptor 2, are developed as novel MRI contrast agents for bone metastasis imaging. Upon administration in mice bearing tumor grown from breast cancer cells, MR images show targeting enhanced retention of antibody-labeled at the site.
Glucocorticoids are released after hypothalamus-pituitary-adrenal axis stimulation by stress and act both in the periphery brain to bring about adaptive responses that essential for life. Dysregulation of response can precipitate psychiatric diseases, particular depression. Recent genetic studies have suggested glucocorticoid carrier transcortin, also called corticosteroid-binding globulin (CBG), may an important role response. We investigated effect partial or total transcortin deficiency...
Background Polyphenols are naturally occurring organic compounds found in plants. Research suggests that their intake reduces the risk of cognitive decline and related dementias. Grapes blueberries polyphenol-rich foods have attracted attention for potential cognitive-enhancing effects.

Depressive disorders represent a major public health concern and display continuously rising prevalence. Importantly, large proportion of patients develops aversive side effects and/or does not respond properly to conventional antidepressants. These issues highlight the need identify further therapeutic strategies, including nutritional approaches using natural plant extracts with known beneficial impacts on health. In that context, growing evidence suggests saffron could be particularly...
Increases in oxidative stress have been reported to play a central role the vulnerability depression, and antidepressant drugs may reduce increased patients. Among plants exerting anti-inflammatory anti-oxidant properties, saffron, spice derived from flower of Crocus sativus, is also known for its positive effects on potentially through SSRI-like properties. However, molecular mechanisms underlying these their health benefits humans are currently unclear. Using an original ex vivo clinical...
Treatment of anxiety and depression predominantly centres around pharmacological interventions, which have faced criticism for their associated side effects, lack efficacy low tolerability. Saffron, is reportedly well tolerated in humans, has been recognised its antidepressant anti-anxiety properties. Indeed, we previously reported upon the saffron extract supplementation healthy adults with subclinical anxiety. However, molecular aetiology remains unclear. In a rodent model low-grade...
The Mediterranean diet (MD) and its bioactive constituents have been advocated for their neuroprotective properties along with capacity to affect gut microbiota speciation metabolism. Mediated through the brain axis, this modulation of may partly contribute MD. To explore potential interaction, we evaluated a novel blend (Neurosyn240) resembling in rodent model chronic low-grade inflammation. Behavioral tests cognition, proteomic analysis, 16S rRNA sequencing, 1H NMR metabolomic analyses...
Belight3TM, a nutricosmetic formulation containing polyphenol-rich extracts, has previously been demonstrated to be safe and effective in brightening skin color dark spots clinical study involving Asian volunteers. The aim of this was investigate the efficacy lightening Caucasian population, which is characterized by lighter pigmentation greater visibility hyperpigmentation, as well determine whether supplementation increased sensitivity UV exposure. A randomized, double-blind,...
Sleep disorders may increase neurodegenerative diseases risks and alter gut microbiota composition. Saffron (Crocus sativus) supplementation has been linked to sleep improvements microbiome changes, but its effect on quality through microbiota-brain axis modulation remains unexplored. A randomised, placebo-controlled pilot study of saffron (30mg/day for 4-weeks) was conducted with 52 older adults (55-85 years) experiencing complaints. Subjective objective were measured using validated...
<sec> <title>BACKGROUND</title> Sleep disturbances are highly prevalent and associated with an increased risk of mental physical health disorders. Given the limitations pharmacological treatments, natural interventions such as saffron extract have attracted growing interest for their potential to improve sleep stress-related outcomes. </sec> <title>OBJECTIVE</title> To examine effect a standardized (Safr’Inside™) on quality, insomnia symptoms, stress, psychological well-being in adults...
Aim: Natural interventions for sleep disturbances, such as saffron extract, are gaining scientific and clinical interest. This 3-arm, randomized, double-blind, placebo-controlled trial examined the effect of a standardized extract (Safr'InsideTM) on sleep, stress, other associated psychological outcomes in 165 men women reporting moderate insomnia. Methods: Participants received daily capsule containing 30 mg 20 or placebo (maltodextrin) 4 weeks. The primary endpoint was change insomnia...
Overhauser‐enhanced MRI (OMRI) offers the potentiality of detecting low‐concentrated species generated by specific biological processes. However molecular imaging applications OMRI need significant improvement in spatial localization. Here it is shown that 3D‐OMRI a free radical injected tumor‐bearing mice can be performed at high anatomical resolution constant field. A 30 mm cavity operating 5.43 GHz was inserted C‐shaped magnet for proton 0.194 T. Nude with or without brain‐implanted C6...
A knowledge of the spatial localization cell vehicles used in gene therapy against glioma is necessary before launching therapy. For this purpose, MRI tracking performed by labeling with contrast agents. In context, goal study was to follow noninvasively chemoattraction therapeutic microglial cells a human model triggering Silica nanoparticles grafted gadolinium were label microglia. These vehicles, expressing constitutively thymidine kinase suicide fused green fluorescent protein gene,...
