Effects and mechanisms of lifespan extension and healthspan promotion induced by Limosilactobacillus reuteri (Lactobacillus reuteri) A21041 [PDF]

Frontiers in Nutrition
BackgroundNowadays probiotics have been widely used in the fields of food, medicine and agriculture. In this study, we investigated the anti-aging effects of the probiotic strain of Limosilactobacillus reuteri A21041 using Caenorhabditis elegans ...

An unsupervised learning approach to identify novel signatures of health and disease from multimodal data

Genome Medicine, 2020
Background Modern medicine is rapidly moving towards a data-driven paradigm based on comprehensive multimodal health assessments. Integrated analysis of data from different modalities has the potential of uncovering novel biomarkers and disease ...

A set of common buccal CpGs that predict epigenetic age and associate with lifespan-regulating genes

iScience, 2022
Summary: Epigenetic aging clocks are computational models that use DNA methylation sites to predict age. Since cheek swabs are non-invasive and painless, collecting DNA from buccal tissue is highly desirable.

Changes in insulin, adiponectin and lipid concentrations with age are associated with frailty and reduced quality of life in dogs

Scientific Reports
Declining metabolic function with aging is a conserved phenotype across many species. While aging-associated changes in metabolic status have been investigated rigorously in humans, less is known about metabolic aging in dogs.

Translational immune and metabolic markers of aging in dogs

Scientific Reports
Dogs serve as a promising aging model due to their genetic diversity, condensed lifespan, and shared living environment with humans. Alterations in the immune and metabolic parameters are hallmarks of aging in humans, but few studies have investigated ...

A novel benchmark for COVID-19 pandemic testing effectiveness enables the accurate prediction of new Intensive Care Unit admissions

Scientific Reports, 2021
The positivity rate of testing is currently used both as a benchmark of testing adequacy and for assessing the evolution of the COVID-19 pandemic. However, since the former is a prerequisite for the latter, its interpretation is often conflicting.

Saturated fatty acid concentrations are predictive of insulin sensitivity and beta cell compensation in dogs

Scientific Reports
Chronic feeding of a high fat diet (HFD) in preclinical species induces broad metabolic dysfunction characterized by body weight gain, hyperinsulinemia, dyslipidemia and impaired insulin sensitivity.

Pain-centered symptom-language co-occurrence networks differ between interstitial cystitis/bladder pain syndrome and fibromyalgia in Reddit patient discourse

Scientific Reports
Interstitial cystitis/bladder pain syndrome (IC/BPS) and fibromyalgia (FM) are chronic pain conditions frequently discussed within shared conceptual frameworks such as central sensitization.

Mitochondrial TrxR2 regulates metabolism and protects from metabolic disease through enhanced TCA and ETC function

Communications Biology, 2022
TrxR2 overexpression in mice enhances metabolism and prevents high-fat diet induced metabolic deficits in mice through alteration in function of several enzymes in the tricarboxylic acid cycle and complexes of the electron transport chain.

Utilization of defined microbial communities enables effective evaluation of meta-genomic assemblies

BMC Genomics, 2017
Background Metagenomics is the study of the microbial genomes isolated from communities found on our bodies or in our environment. By correctly determining the relation between human health and the human associated microbial communities, novel mechanisms
