In traditional Brazilian medicine, tubers extracts from are widely used in the treatment of skin pigmentation disorder. However, studies that evaluate its benefits in the treatment of this disorder are non-existent. Thus, this work aims to investigate the bioactivity of extracts in cell culture and murine model of Vitiligo and correlating with its phenolic profile. The metabolic profiling from the bioactive extracts was obtained by LC-DAD-MS, FTIR, NMR, and CE-UV. The murine model of Vitiligo was induced with 5% hydroquinone in C57BL/6 male mice, which were treated or not with 100 mg/kg of roasted tuber aqueous extract. In Vitiligo model assay was observed hair follicle repigmentation and reduction of the epidermal layer thickness at the histopathological level, in the animals treated with aqueous extract of roasted tubers. The present study provides new molecular insight and scientific evidence on the potential utility of the extract of against Vitiligo.

Omics data provide a plethora of quantifiable information that can potentially be used to identify biomarkers targeting the physiological processes and ecological phenomena of organisms. However, omics data have not been fully utilized because current prediction methods in biomarker construction are susceptible to data multidimensionality and noise. We developed OmicSense, a quantitative prediction method that uses a mixture of Gaussian distributions as the probability distribution, yielding the most likely objective variable predicted for each biomarker.

Introduction: Gut microbiota alterations have been implicated in Autism Spectrum Disorder (ASD), yet the mechanisms linking these changes to ASD pathophysiology remain unclear.
Objectives: This study utilized a multi-omics approach to uncover mechanisms linking gut microbiota to ASD by examining microbial diversity, bacterial metaproteins, associated metabolic pathways and host proteome.
Methods: The gut microbiota of 30 children with severe ASD and 30 healthy controls was analyzed.

Follicular ovarian cysts (FOCs) are prevalent reproductive disorders in both humans and animals, especially in livestock, where they cause economic losses by reducing fertility and productivity. FOCs are marked by a dominant follicle that fails to ovulate, disrupting the estrous cycle and reproductive efficiency. Previous studies indicate that the follicular fluid (FF) in cystic ovaries shows oxidative imbalance, affecting oocyte quality by altering glutathione peroxidase (GPX1) and selenium pathways.

An approach combining enzymatic inhibition and untargeted metabolomics through molecular networking was employed to search for human recombinant full-length protein tyrosine phosphatase 1B (PTP1 B) inhibitors from a collection of 66 mangrove-associated fungal taxa. This strategy prioritized two strains (IQ-1612, section , and IQ-1620, section ) for further studies. Chemical investigation of strain IQ-1612 resulted in the isolation of a new nonanolide derivative, roseoglobuloside A (1: ), along with two known metabolites (2: and 3: ), whereas strain IQ-1620 led to the isolation of four known naphtho-γ-pyrones and one known diketopiperazine (4: -8: ).
